20100062146 | METHOD FOR PRODUCING BATTERY ELECTRODE AND APPARATUS FOR PRODUCING BATTERY ELECTRODE - The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale. | 03-11-2010 |

20090090749 | Method for preventing leaking of molten metal in injection molding of metal material - This is provided a method for preventing leaking of molten metal from a nozzle in an injection apparatus provided with a plunger within a cylinder body, a supply opening formed in an upper portion of the cylinder body, and a furnace for melting and holding the metal material provided on a top portion of the injection cylinder and having an outlet at the bottom end of the furnace communicated with the supply opening. The method comprises the following steps: metering the molten metal by travel of the plunger head backward from the most forward position to the backward position at the rear of the supply opening while maintaining nozzle touching after completion of an injection step and supplying the molten metal from the furnace into the cylinder body through the supply opening, after completion of the metering, closing the supply opening by travel of the plunger head forward at low speed from the backward position to a stand-by position ahead of the supply opening for cutting off the communication between the molten metal in the cylinder body and the molten metal in the furnace. | 04-09-2009 |
20090165984 | INJECTION CYLINDER IN INJECTION APPARATUS FOR MOLDING METAL MATERIAL - Leakage of molten metal material from between a cylinder body having a tight-fitting liner and a nozzle member of an injection apparatus is prevented through the interaction of the nozzle member and a coupling ring with the liner. | 07-02-2009 |
20090188644 | CONTROL METHOD FOR SUPPLYING INERT GAS DURING METAL MOLDING - A control method for supplying an inert gas from an inert gas source to a storage container for a molten metal through a gas feed path provided with a flow sensor for monitoring the gas flow rate and a solenoid valve for opening and closing the gas feed path for use with metal molding. The control method comprises; turning off the solenoid valve at a temperature of the storage container is equal to or lower than a preset temperature, and turning off the flow sensor; turning on the solenoid valve at the temperature of the storage container has reached the preset temperature, and turning on the flow sensor; and stopping the output of the heater of the storage container when a flow rate of the inert gas is equal to or lower than the preset amount; these steps are controlled in accordance with a command signal from a controller. | 07-30-2009 |
20150014878 | HOT RUNNER NOZZLE AND MOLD FOR FORMING MULTI-LAYER MOLDED ARTICLE USING THE SAME - At a filling termination stage when performing multi-layer molding by means of a hot runner nozzle, an intermediate layer in a multi-layer molded article is prevented from being formed in a shape causing the intermediate layer to enter into a sprue in a portion of a mold cavity in a mold corresponding to the sprue. The multi-layer molded article with no intermediate layer being exposed in a sprue cut portion can be therefore obtained. In this manner, a diameter of a discharge port opening and closing mechanism part for opening and closing the resin discharge ports in the shut pin is made different from a diameter of a nozzle gate opening and closing mechanism part configured of the projection for pushing out the molten resin in the nozzle gate. | 01-15-2015 |

20090178776 | DEVICE FOR MELTING, STORING, AND FEEDING METAL MATERIAL FROM BAR-SHAPED METAL MATERIAL INTENDED FOR INJECTION APPARATUS FOR MOLDING METAL PRODUCT - A device for melting, storing, and feeding a metal material is provided which can store a large amount of molten metal material corresponding to molding cycles with a compact configuration, using barrels to melt bar-shaped metal materials and a tank-and-barrel storage unit to store the molten metal material. The storage unit for the molten metal material is composed of an upper storage tank and a lower material temperature control barrel having a smaller diameter, the barrel being perpendicularly arranged under and in communication with the bottom center of the tank. The melting barrels for bar-shaped metal materials are made of barrel bodies having an inside diameter and a length appropriate to accommodate the bar-shaped metal materials. A more than one melting barrel is vertically arranged in parallel on a lid member of the storage tank, with their bottom openings facing the inside of the storage tank. | 07-16-2009 |
20150079321 | HOT RUNNER NOZZLE, METAL MOLD EQUIPPED WITH HOT RUNNER NOZZLE, AND MOLDING METHOD AND MOLDED PRODUCT PROVIDED BY METAL MOLD - When a plurality of striped molded products are molded at a time, the molded products having a striped pattern and an outstanding design property are obtained by preventing part of molten resins from being unevenly distributed in an inappropriate manner when being fed into a cavity of a metal mold. A hot runner nozzle is provided with a first resin flow path and a plurality of second resin flow paths. The first flow path has a funnel section which continues with a nozzle gate at a centripetal position and which allows a first molten resin to be gathered at the centripetal position of the funnel section so as to feed the resin into the nozzle gate. The second resin flow paths have a plurality of corresponding discharge ports facing and communicating with the funnel section of the first resin flow path, each of the discharge ports being disposed around the centripetal position, so that the second molten resin different from the first molten resin is fed into the funnel section. | 03-19-2015 |

20130026431 | PIPE LAYER AND WARM-UP METHOD FOR PIPE LAYER - A warm-up pilot pressure control unit adjusts pilot pressure inputted to a first flow channel open/close unit so that the flow channel open/close unit is switched to an open state when a warm-up start state is entered under the necessary condition that a first winch operation member is in a neutral position. When the first flow channel open/close unit is in the open state, a first pump displacement adjustment unit adjusts the displacement of a first hydraulic pump so that the differential pressure between a first pump hydraulic circuit and a first warm-up hydraulic circuit becomes constant at a predetermined set pressure. | 01-31-2013 |
20140338317 | PIPELAYER - A pipelayer includes a pilot pressure control unit. The pilot pressure control unit supplies hydraulic fluid to a pilot port of a warm-up control valve so that the warm-up control valve enters an open state when a winch control valve is in the closed state. The pilot pressure control unit drains hydraulic fluid from the pilot port of the warm-up control valve so that the warm-up control valve enters the closed state when the winch control valve is in the open state. The stroke amount from the stroke end of the closed side of the spool of the warm-up control valve when the meter-out opening of the warm-up control valve is fully closed is larger than the stroke amount from the stroke end of the closed side of the spool of the winch control valve when the meter-in opening of the winch control valve is fully closed. | 11-20-2014 |
