Title: Conveying control system in electrophotographic recorder
Inventor: KONDOU OSAMU
IPC: G03G15/00
Filed: 1979-11-15
Abstract: PURPOSE:To provide a system of preventing reoccurrence of a jam state which is caused at the returning-on of an electric power source by setting the conveying system together with the control system to an initial state at the turning-on of the  power source. CONSTITUTION:When an electric power source 38 is turned on, an automatic clearing circuit 39 outputs a signal AC to a CPU32, and the CPU32 is initially set. At the same time, a timer circuit 40 is driven by the signal AC, which is turn outputs a timer signal. This causes conveying rollers 13, 17, 18 and discharge roller 20 to be operated for a given time, so that the recording paper P which has left on the conveying paths 11, 16 on account of a jam state or service interruption is discharged onto a tray 21. Next, when the signal START is inputted to a select circuit 31, the CPU32 outputs a command signal to a conveying system drive unit 34 and a drive unit 36 for a feed roller 10, by which the recording paper P is successively conveyed. Since the recording paper P which had left on the conveying paths 11, 16 owing to the jam etc. has already been discharged onto the tray 21, hence the reoccurrence of the jam etc. may be prevented.

Title: Uniform joint
Inventor: KOMEICHI SHIGEKI
IPC: F16D3/2245
Filed: 1980-10-23
Abstract: PURPOSE:To improve efficiency of assembling, processing and working by tapering a ball retaining window of a bar field type uniform joint in such a manner as to be spread out inward of a cage. CONSTITUTION:The upper and lower edges of a cage 2' are tapered such a manner as to be spread out inwards. The upper and lower edges of a window portion have an angle alpha of about 10 deg. with a horizontal direction, whereby as the cage is inclined, an initial pressing rate is increased on the side of pushing up the cage, while the ball pressing rate is decreased on the opposite side. This results in preventing a lock phenomenon due to a load difference for sliding a ball. A window width working can be accomplished only by inclining a tool shaft at a certain set amount. It is not necessary to apply grease to a ball at time of assembly. Thus, efficiency of assembling, processing and working can be improved.

Title: Self-holding array type switch device, switch switching method, and its production
Inventor: TANAKA HIDENAO
IPC: H04Q3/52
Filed: 1993-06-21
Abstract: PURPOSE:To miniaturize switches to make the device in a large scale by using vertical and horizontal wirings like a lattice to arrange switches and using a magnetic circuit having the self-holding function to control the switching of switches by the change of magnetization due to heating. CONSTITUTION:When a mobile part front end 11b is brought into contact with a fixed electrode 12, a laser beam LB is focused on the electrode 12, and it is heated to the vicinity of the Curie point to reduce the magnetization. Then, the attraction of the mobile part front end 11b to the electrode 12 is weakened, and the front end 11b is attracted by the magnetic field from a fixed electrode 13 and is switched to the electrode 13. Even after heating of the electrode 12 is stopped, the front end 11b is stably self-held. When the electrode 13 is heated furthermore, magnetization of the electrode 13 is lost, and the front end 11b is attracted to the electrode 12 and is switched. When all of electrodes 12 and 13 are individually heated by the control of right and left actuators 9 and 10 of a voice coil motor, switching is performed in all matrix intersections. Consequently, switching from vertical wirings Y1 and Y2 to horizontal wirings X1 to X4 is possible.
