Title: Inner rotor motor
Inventor: NISHIYAMA HIROSHI
IPC: H02K21/16
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce the cogging torque largely without reducing magnetic flux amount which contributes to torque, by involving a stator substrate with a shaft fixed, and forming a salient pole front end part shape at a stator core inner periphery into a straight shape. SOLUTION: At the inner periphery of a stator core 1, a driving magnet 6 retained at the outer periphery of a rotor frame 5 with a housing 4 fixed in the center, is disposed so as to face each other. A ball bearing 7 is retained in the center of a housing 4, and a rotor is supported so as to be rotated freely by inserting a shaft 9 fixed to a stator substrate 8 in the ball bearing 7. The shape of a stator core inner periphery surface shape 11 at a salient pole front end 10 of the stator core 1 is formed into a straight shape which can attain easy processing. By forming a gap between the stator core 1 and the driving magnet 6 so as to spread gradually from its center past to its end, energy change in the gap at the time of rotating the rotor is made moderate, thus enabling to reduce cogging torque largely.

Title: Fixing device for electrophotographic copying device
Inventor: NISHIMURA HIDEYUKI
IPC: G03G15/01
Filed: 1990-09-20
Abstract: PURPOSE:To maintain the prescribed thickness of a fluororesin layer on the surface of a fixing roller by giving the fluororesin on the surface of a fluororesin roller to the fluororesin layer on the surface of the fixing roller. CONSTITUTION:When a power source switch is turned on and temperature detected by a temperature sensor 32 is <=100 deg.C, the upper and the lower heat rollers 17 and 18 of a fixing device 10 are rotated and a solenoid 23 is turned on. At this time, the roller 18 is rotated in a direction B and the roller 17 is rotated in a direction C. Then, the rotation of the roller 18 is transmitted to the fluororesin roller 21 through a belt 24, a fulcrum shaft 22 and a belt 25 and the roller 21 is rotated in the direction B which is reverse to the roller 17. Besides, a roller supporting member 20 is pressed by the solenoid 23 and turned in the direction B. Then, the roller 21 is brought into contact with the roller 17. At this time, the fluororesin is given to the roller 17 from the roller 21 by the friction of the fluororesin layer on the surface of the roller 21 and the fluororesin layer on the roller 17. As the result, the fluororesin layer of the roller 17 is maintained at a prescribed thickness.

Title: Radiation-resistant resin composition
Inventor: TANAKA TAKAO
IPC: C08K5/13
Filed: 1991-10-01
Abstract: PURPOSE:To prepare the title compsn. excellent in radiation resistance and processibility at a low cost by compounding a chlorosulfonated polyethylene with a benzophenone compd. CONSTITUTION:The title compsn. is prep. by compounding 100 pts.wt. chlorosulfonated polyethylene with 2-70 pts.wt. benzophenone compd. of the formula (wherein R is 1-8C alkyl). An amt. compounded of the compd. lower than 2 pts.wt. leads to hardening of the compsn. due to decrease in elongation when exposed to a radiation; an amt. higher than 70 pts.wt. causes blooming to give an inferior appearance. The compsn. is free from blooming, thus preventing degradation in finish, and has an improved radiation resistance.

Filed: 1986-10-27
Abstract: PURPOSE:To accurately drive a pickup and to facilitate assemblage and repairs by linking a drive part with the pickup in the feed direction without clearance and executing a part screw fitting of a nut and a screw rod. CONSTITUTION:A pin 6 of a transmitting member 5 is inserted into a long hole 4 of a pickup 1 to make a linkage with a certain extent of clearance.
