Title: Starter
Inventor: KAJINO SADAYOSHI
IPC: F02N15/02
Filed: 2002-04-26
Abstract: <P>PROBLEM TO BE SOLVED: To improve engine startability without changing center pitch Cp between a pinion gear 3 and a ring gear.  <P>SOLUTION: The pinion gear 3 is formed by the same gear cutting material as that of a first gear having the number of teeth of 11 sheets, has the same diametral pitch as that of the first gear by performing gear cutting as a minus transfer for the gear cutting material and is provided to have the number of teeth (12 sheets) more than that of the first gear by one sheet. The center pitch Cp between the pinion gear 3 and the ring gear therefore is the same as the center pitch Cp when the first gear is used as the pinion gear 3. A gear ratio (the number of sheets of ring gears/the number of sheets of pinion gears) with the ring gear becomes small by increasing the number of teeth of the pinion gear 3 from 11 sheets to 12 sheets in this way, and thereby engine speed is raised at the time of cranking to improve engine startability.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a flat plate vaporizer. SOLUTION: The flat plate vaporizer has such a structure as the common chamber of a substrate having specified diameter and depth for containing refrigerant is sectioned into a vaporization cavity region, a capillary tube region surrounding the vaporization cavity region, and a manifold region surrounding the capillary tube region, a wick structure is formed in the capillary tube region, and an exhaust means including a section for exhausting vapor phase refrigerant produced in the vaporization cavity region to the outside is provided on an upper plate. A small and thin cooler which can be cooled without requiring any external power can be obtained using that evaporator.  Since liquid state refrigerant can be isolated from evaporated gas phase refrigerant by the capillary tube region, lowering in the fluidity of fluid due to mixture of gas and liquid can be suppressed efficiently and heat exchanging characteristics can be enhanced significantly.
