Title: Master plate for planographic printing
Inventor: KATO EIICHI
IPC: G03G5/08
Filed: 1989-01-31
Abstract: PURPOSE:To improve an electrostatic characteristic and to improve desensitization characteristic by incorporating hydrophilic resin particles specified in average grain size into the above plate and specifying a binder resin. CONSTITUTION:The hydrophilic resin is dispersed as particles in a photo conductive layer. The important requirement thereof is that the average particle size of the resin is the same as the largest particle of photoconductive zinc oxide particles or small than the same. The specific surface area is small with such hydrophilic resin particles and the interaction with the zinc oxide surface is eliminated as compared to the resin which exists in the form of particles in the photoconductive layer. The binder resin is, for example, a resin A and the weight average mol. wt. thereof is 3X10<3> to 1X10<4>. The existence ratio of the copolymer component contg. the assigned polar group is 0.5 to 20wt.%. The polar group contained in the binder resin A adsorbs to the stoichiometrical defect of the photoconductive zinc oxide and since this resin is a low mol. wt. material, the resin improves the property to cover the surface of the photoconductive zinc oxide. The excellent printing characteristic is developed in this way and the desensitization of the non-image part is maintained optimum.

Title: Differential gear with differential limiting mechanism
Inventor: TANAKA TOSHIFUMI
IPC: F16H48/22
Filed: 1989-01-30
Abstract: PURPOSE:To improve running performance upon normal operation with slip escape driving torque transmitted to the other wheel, when the one side wheel is in slipping, by setting a cam angle in each cam part of a pressure plate and cam bolt to the angle amplifying elastic force of an elastic member. CONSTITUTION:In this differential gear with a differential limiting mechanism, in the case of initially set torque increasing to a large value (m) and in the case of a coefficient of friction received to a low speed side wheel decreasing to a value (s) in a slip state, large differential limiting force is generated for driving torque generated exceeding driving torque (p) necessary for a wheel to escape from a slip condition. Further in normal running, in case of the differential limiting force not necessary with a coefficient of friction in a large value (t) with a road surface, thrust force by meshing a side gear is in a small value for preload force and the initially set torque with almost no influence to the differential limiting force. Consequently, a proportion of the differential limiting force is decreased to the driving torque approaching the driving torque in an ordinary differential gear.
