Title: Crank mechanism for increasing torque and reducing necessary torque in rotating reciprocating motion converting device
Inventor: ISHIKAWA YOSHIHIRO
IPC: F02B75/04
Filed: 2001-10-17
Abstract: PROBLEM TO BE SOLVED: To increase torque and reduce necessary torque as compared to a conventional rotating reciprocating motion converting device. SOLUTION: A crankshaft 12 is rotated while an eccentric movement shaft 6 is loaded inside of a connecting rod 4 under a condition that a steel ball 7 is attached on a semispherical dent part of a round side of the eccentric movement shaft 6 on a ball groove 11 cut on an outer circumference of a crank pin 10. The crankshaft 12 shifts in left and right by a displacement corresponding to inclination angles of the ball groove 11 in respect to the crank pin 10 and gets eccentric by the shift.

Title: Photoelectric conversion element and its manufacturing method
Inventor: OKAZAKI SHINYA
IPC: H01L31/04
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To compensate the increase in series resistance in the case of shallow joint without reducing the light receiving area. SOLUTION: An insulation layer 3 is formed on an n-type semiconductor layer 2 where a high-concentration impurity doped layer on the surface is removed by etching. Thus, the surface rejoint of minority carriers due to dangling bond or impurity level or the like on the surface of the n-type semiconductor layer 2 is significantly reduced than that in a conventional violet cell. In addition, an opening 3a for contact is formed in the insulation film 3, and a transparent conductive film 4 is entirely formed on the insulation film 3 and opening 3a for contact. Thus, series resistance increasing accompanied with the reduction of film thickness of the n-type semiconductor layer 2 can be compensated without reducing the light receiving area.
