Title: Developing device
Inventor: UMIZUMI YOSHIHIKO
IPC: G03G15/36
Filed: 1982-07-12
Abstract: PURPOSE:To extend the change period of a developer while holding constant print density, by providing a voltage applying means for voltage application and an applied voltage varying means between a latent image forming medium and a developing means. CONSTITUTION:A characteristic change of the developer depends upon the operation time of a developing device and development with constant print density is possible even with a developer having changed in characteristics by applying a developing voltage corresponding to the change. Therefore, once printing density and the operation time of the development device are inputted to a control part 6, the control part 6 calculates an adequate development voltage corresponding to those pieces of information and outputs a set value to a voltage controller 5. The voltage controller 5 applies the development voltage to a sleeve electrode 3 according to the set value from the control part 6. Consequently, easy maintenance and great cost reduction are expected.

Title: Brazing alloy for sintered alloy
Inventor: SEKIGUCHI NAOYOSHI
IPC: B23K35/30
Filed: 1978-10-02
Abstract: PURPOSE:To obtain a brazing alloy for sintered alloys, with which brazing is ensured and strength and corrosion resisting property of the brazed portion can be maintained excellently, by mixing a specified amount of Ni to Cu and a small quantity of Sn as occasion demands. CONSTITUTION:This alloy is composed of 60-90wt% of Cu, 10-40% of Ni and 1-5% of Sn. The Sn is mixed to the alloy when it is required. This brazing alloy is used after it is powdered for brazing of sintered alloys of iron based material, etc. When brazing is made in this manner, melting of Cu and Ni takes place at the same time and the melted Ni covers pores of the sintered alloy and impregnation of the Cu into pores is prevented. Thus a effective brazing can be executed between sintered alloys and between sintered alloys and steel. Moreover, by the addition of small amount of Sn, the melting point of the brazing alloy is lowered and almost all Ni can be melted and filling ratio of braze against the brazing surface can be increased. Thus brazing can be executed surely with this brazing alloy.

Title: R.p.m. reduction control method for driven shaft
Inventor: NISHIDA TAKAO
IPC: F16D48/02
Filed: 1980-09-01
Abstract: PURPOSE: To save motive power consumption when the speed is reduced from high to low by regenerating fluid pressure to maintain a desired low R.P.M. after once decompressing the fluid pressure in a hydraulic non-step transmission gear unit to zero in order to allow free deceleration thereof.  
     CONSTITUTION: Upon receiving a signal to reduce r.p.m. of a blower shaft 2, a control unit 12 commands a hydraulic pressure controller 11 to shut off the hydraulic pressure from a fluid pump 3 completely. Subsequently, a piston 10' is released through a return spring, and a motor shaft 1 and the blower shaft 2 are disconnected, which makes the blower r.p.m. liberally reduced gradually. When a desired low r.p.m. is detected at an r.p.m. counter 13, a signal to release the above command (hydraulic pressure shut off) is transmitted to the hydraulic pressure controller 11 from the control unit 12. Thus the load applied to the motor shaft 1 is diminished while the blower shaft 2 is in a low speed transition.

Title: Shift control method for automatic transmission for vehicle
Inventor: TEI UGEN
IPC: F16H61/02
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To make a proper shift by detecting the differential value of the input shaft revolving speed against the elapsed time during the 4-3 shift process, extending the shift time to a third speed shift stage when the differential value is negative, and implementing a 3-2 speed shift without extending the 4-3 speed shift time when the differential value is not negative. SOLUTION: Whether a 4-2 shift is necessary or not is judged (S 100). If it is necessary, a 4-3 speed shift command is generated (S110). Whether the differential value (dNt/dt) of the turbine revolving speed Nt against time (t) is larger than the prescribed value A or not is confirmed during the 4-3 speed shift process (S120). If the differential value is not larger than the prescribed value A, the completion of the 4-3 speed shift is confirmed (S121), then a 3-2 speed shift is implemented. If the differential value is larger than the prescribed value A, the 4-3 speed shift is delayed by the shift delay time (S130). After the elapse of the shift delay time is confirmed (S140), the completion of the 4-3 speed shift is confirmed (S150). After this completion is confirmed, the 3-2 speed shift is implemented (S160).
