20080236155 | HYDROSTATIC CONTINUOUSLY VARIABLE TRANSMISSION - A hydrostatic continuously variable transmission includes a swash plate type plunger hydraulic pump and a swash plate type plunger hydraulic motor connected via a hydraulic closed circuit, an inclined angle of a swash plate of the hydraulic motor is variably controlled for continuous shift control. A lock-up mechanism closes the hydraulic closed circuit to make lockup executed when the quantity of oil that flows from the hydraulic pump into the hydraulic motor decreases according to variable control over the inclined angle of the swash plate. The input rotation of the hydraulic pump and the output rotation of the hydraulic motor are substantially synchronous. The lock-up mechanism is operated when lockup control oil pressure is applied and closes the hydraulic closed circuit. A lockup control oil passage that supplies the lockup control oil pressure is provided with an opening opened and closed according to the inclination of the swash plate | 10-02-2008 |

20100229824 | LUBRICATION STRUCTURE FOR HYBRID TYPE VEHICLE POWER UNIT - In a hybrid type vehicle power unit including a first oil pump interlockingly connected to a crankshaft so as to supply at least a lubricating oil to an engine and a transmission, and a second oil pump for supplying the lubricating oil to the transmission, it is not necessary for an electric motor to be exclusively used for the second oil pump. Thus, a reduction in the number of component parts and a reduction in the cost of manufacturing are achieved. The second oil pump is interlockingly connected to an electric motor capable of transmitting a driving torque to an output shaft through the transmission. | 09-16-2010 |
20110061492 | LUBRICATING OIL FEEDING STRUCTURE - A lubricating oil feeding structure that permits an adequate amount of lubricating oil to be fed to those parts around the transmission while avoiding an excess supply of lubricating oil to the lubricating oil passage in the shaft of the transmission. The transmission has a space (as a recess to hold the shaft therein) in which is arranged the oil guide part. The oil guide part has the bottomed cylinder, with its one end opened, the flange that flares outward at the open end of the bottomed cylinder, and the oil holes that communicate between the inside and the outside of the bottomed cylinder. The oil guide part is arranged in the space in such a way that the flange comes into contact with the outer race of the bearing. | 03-17-2011 |

20090147035 | INSPECTIVE EJECTION METHOD FOR FLUID EJECTION APPARATUS AND FLUID EJECTION APPARATUS IMPLEMENTING THE METHOD - An inspective ejection method using inspective injection data, including unit ejection data and non-ejection data, for causing fluid to be ejected from nozzle orifices of a fluid ejection apparatus. The unit ejection data is used for individually inspecting each of a group of continuous nozzle orifices of a predetermined number M, less than total number Q. The non-ejection data having a length of at least Q−M is continuously added to a leading or trailing side in a unit ejection data reading direction. A transfer start address is selected in the area of the inspective ejection data at an interval of M, while avoiding duplication of the transfer start address. The inspective ejection data is transferred to an ejection driving unit, starting from the selected transfer start address. The selecting transferring steps are repeated a whole number of times that is Q/M or greater, while changing the transfer start address. | 06-11-2009 |
20090189933 | Nozzle missing determining device for liquid ejecting apparatus , liquid ejecting apparatus, and method of determining nozzle missing - A nozzle missing determining device that determines a nozzle missing state of a liquid ejecting apparatus, the nozzle missing determining device determines whether all the nozzles having predetermined positional relationship are non-ejection nozzles based on a test result data, the predetermined positional relationship includes positional relationship of nozzles of which dots that are formed by a same type of liquid are next to each other in accordance with the determined record mode. | 07-30-2009 |

20120250335 | ILLUMINATION APPARATUS AND FAN UNIT FOR ILLUMINATION APPARATUS - An illumination apparatus including an LED, a heat sink that dissipates heat of the LED, a fan apparatus provided with a blade and a motor, and a case provided with an opening on the heat sink side, wherein the fan apparatus is provided between the case and the heat sink so that the blade is arranged closer to the heat sink side than the motor. The above configuration allows the fan to be arranged in a large diameter portion of a sphere, and therefore when the illumination apparatus is applied to a bulb type LED lamp whose illumination side on which the LED is arranged is thick and whose socket side is thin, the cooling fan need not be reduced in size. Therefore, it is possible to realize an illumination apparatus having high cooling efficiency and a long useful life. | 10-04-2012 |

20150259030 | CHAIN GUIDE STRUCTURE FOR CHAIN DRIVE TYPE TRANSMISSION MECHANISM - A chain guide structure for a chain drive type transmission mechanism which ensures that even when a solid matter, such as a small stone, gets nipped and a strong impact is exerted on a chain guide, the chain guide deforms so as to absorb the impact and permit the small stone or the like to be swiftly eliminated. The chain guide fastened to the engine case is provided so as to cover a drive chain wound around a drive sprocket, at a part of the periphery of the drive sprocket and in an arcuate form. The chain guide is formed with a brittle portion lower in strength than other portions thereof. The brittle portion is located above and in the vicinity of a front end portion at which the chain guide is situated closest to the drive chain. Thus, an engine case can be protected from damage. | 09-17-2015 |
