20090014915 | METHOD FOR FEEDING MOLTEN RESIN MASS AND APPARATUS THEREFOR - A method of feeding a molten resin mass, which is capable of causing a molten resin mass to fall down into a female mold for compression molding without delay in the timing from a cylindrical transfer guide that cuts a portion of a molten resin extruded from a die head of an extruder and transfers it to a female mold for compression forming, and an apparatus therefor. The apparatus for feeding the molten resin mass has a cylindrical transfer guide which transfers a molten resin mass obtained by cutting a predetermined amount of a molten resin extruded from a die head of an extruder to a female mold for compression molding, wherein the transfer guide is provided with vibration-generating means for imparting vibration to the transfer guide. In the method of feeding the molten resin mass, the pressure in the cylindrical transfer guide is set to be higher than the pressure in the female mold for compression molding. | 01-15-2009 |
20090096129 | METHOD OF FEEDING COMPOSITE MOLTEN RESIN AND APPARATUS FOR FEEDING THE SAME - A method of feeding a composite molten resin capable of easily forming a multi-kind-multi-layer preform. An apparatus for feeding the composite molten resin has a nozzle portion which includes an outer discharge port in which an outermost annular flow path through which a main layer-forming molten resin flows, meets an outer annular flow path through which a sub-layer-forming molten resin flows inside of the outermost annular flow path; and an inner discharge port in which a shell layer-forming molten resin annularly flowing inside of the outer conflux path, meets the core layer-forming molten resin flowing inside the shell layer; the outer discharge port and the inner discharge port being arranged in this order from the downstream toward the upstream in a direction in which the molten resins flow; wherein provision is made of a shaft-like opening/closing valve for opening and closing the inner discharge port, and a gear pump for intermittently discharging the sub-layer-forming molten resin. | 04-16-2009 |
20100201032 | COMPRESSION-MOLDING APPARATUS AND COMPRESSION-MOLDING METHOD - [Problem] To suppress the deviation of a synthetic resin to be fed to a metal mold and to enable the to-be-compression-molded synthetic resin to be easily molded into a shape of a pre-molded article that is to be molded. | 08-12-2010 |
20130334728 | SYSTEM FOR FEEDING MOLTEN RESIN AND METHOD OF FEEDING MOLTEN RESIN - To efficiently feed a molten resin to the resin holders. An intermittently feeding device works to intermittently feed a transfer unit equipped with resin holders, and has a cam supported by a motor via a support. The cam is rotated by the motor. A cam follower of a moving block meshes with the screw of the cam, and the moving block moves along a support rail accompanying the turn of the cam. The motor rotates at a constant speed, and the transfer unit | 12-19-2013 |
20150289691 | CUP-TYPE CONTAINER AND METHOD OF FORMING THE SAME - A container obtained by compression-forming a thermoplastic resin includes a flange portion, a body portion and a bottom portion. A ratio (L/D) of the height of the container to the diameter of the opening is not less than 1.0, and if the direction of height of a test piece cut out from the body portion of the container is denoted by x and the circumferential direction thereof by y, a half-value width P at a half peak of a Miller index at a diffraction angle 2θ=14.5° that represents the diffraction by the crystal plane ( | 10-15-2015 |

20090160252 | METHOD OF CONTROLLING HYBRID DC POWER SUPPLY SYSTEM - A fuel cell vehicle has a motor driven by an inverter and hybrid DC power supplies including a battery and a fuel cell for supplying electric power to the motor. For preventing a fuse connected to the battery from being blown out, when a motor current Im increases, a first source current flowing from the battery is limited to a range for not blowing out the fuse, and a generated current is increased as much as the first source current is limited. | 06-25-2009 |
20090179623 | METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS - If a lower arm device connection period is non-zero in a previous switching cycle, a first dead time is prohibited from decreasing, and if the lower arm device connection period is zero, the first dead time is allowed to decrease, wherein the first dead time is the dead time provided after the lower arm device connection period in the previous switching cycle but before an upper arm device connection period in the current switching cycle. | 07-16-2009 |
20090212634 | METHOD OF CONTROLLING DC/DC CONVERTER, METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS, AND METHOD OF CONTROLLING DRIVING OPERATION OF ELECTRIC VEHICLE - When a DC/DC converter switches between a primary voltage control mode, a secondary voltage control mode, and a current limiting mode as operation modes, an I-term resetting processor outputs an I term depending on the duty ratio in the operation mode before being switched to a PID processor. The PID processor performs a PID control process based on the input I term. A drive duty ratio setter outputs a drive duty ratio immediately after the control mode switching, which is substantially equal to the duty ratio in the operation mode before being switched. As a result, the duty ratios in the operation mode before being switched and the operation mode after being switched are made continuous with respect to each other. | 08-27-2009 |
20090230917 | METHOD OF PROTECTING ELECTRICITY STORAGE DEVICE IN HYBRID DC POWER SUPPLY SYSTEM - A method protects a battery in a fuel cell vehicle, in which an inverter-driven motor is supplied with electric power from the battery and a fuel cell. If a battery voltage of the battery falls outside of a prescribed range, a primary current and a secondary current that flow through the DC/DC converter, or currents in branch paths that correspond to the primary current and the secondary current, are reduced in order to limit a charging current flowing into the battery or a discharging current flowing from the battery. | 09-17-2009 |
20090243386 | METHOD OF CONTROLLING FUEL CELL VEHICLE AND METHOD OF CONTROLLING DC/DC CONVERTER APPARATUS - A controller is capable of executing direct couple control that directly couples a first power device and a second power device without causing a DC/DC converter to convert voltage. During the direct couple control, a drive signal that causes no voltage conversion is intermittently output to at least one of a plurality of switching devices. | 10-01-2009 |
