Abstract: PURPOSE:To permit high-quality printing without any deviation of printing with a low cost by a method wherein the change of end positions is detected by end position sensors, provided at left-and-right ends, while the printing is started after a predetermined period of time from the point of variation. CONSTITUTION:Left-and-right end positions are detected by two sets of end position detecting means 24, 26, detecting the end positions when a printing head 21 is moved into left-and-right, while printing is started after predetermined periods of times T, T' counted by a timer means 44 from the point of variations of end position signals 36, outputted upon detecting the end positions.

Title: Negative pressure-force converter for automatic transmission
Inventor: SHIMIZU SHIGEHISA
IPC: F16H61/04
Filed: 1990-07-30
Abstract: PURPOSE:To suppress speed change shock and prevent the change of the speed change line by varying spring force acting on a diaphragm according to the operation of a driving deice operated by the electric signal supplied from outside. CONSTITUTION:When an electromagnet 40 is in OFF state, a plunger 42 is pressed to a diaphragm 14 by the pressing force of the second spring 44. When the electromagnet 40 is turned ON, a rightward force acts on the plunger 42, and the plunger 42 is shifted to the rightward direction against the force of the second spring 44. The surface on the atmospheric pressure chamber 18 side of the diaphragm 14 is connected with the spool 28 of a throttle valve 12 through a rod 26, and the diaphragm 14 operates a pressing force on the spool 28 through the rod 26. Accordingly, the throttle valve 12 installed in a valve body 13 adjusts the hydraulic pressure in an oil passage 32, i.e., throttle pressure to the pressure corresponding to the pressing force of a rod 20, having the line pressure supplied from an oil passage 30 as hydraulic pressure source.

Title: Clutch disc
Inventor: NOZAWA KOUJI
IPC: F16D13/64
Filed: 1982-11-19
Abstract: PURPOSE:In a clutch disc in friction type clutch for rolling stock, to prevent gear backlash noise by varying the outer diameter of first step spring such that the spring characteristic will reduce along a curve as the load increases. CONSTITUTION:The outer diameter of a coil spring 11 will vary gradually in axial direction and set to be lower than the spring constant of second step spring 9. With such structure, relative rotation between the flange of spline hub 1, clutch plate 4 and retaining plate 5 due to variation of torque through the clutch disc during power transmission will first compress the coil spring 11. Because of conical shape, the coil spring 11 will deform parabolically as the load increases to allow large relative rotary angle thus to enable smooth transmission of torque. Consequently gear backlash noise of speed change gear can be prevented.

Title: Inverter
Inventor: HAMAOKA KOJI
IPC: H02M7/48
Filed: 1985-09-13
Abstract: PURPOSE:To prevent a switching element from deteriorating by providing a protecting circuit for stopping a power supply of a drive circuit and outputting a signal when a power voltage supplied to the drive circuit decreases and when a heat detection switch operates. CONSTITUTION:Rectifiers 13a-13e are provided at the secondary side of a switching transformer 12. When a power source voltage V7 decreases due to certain cause, a voltage between the emitter and the base of a transistor 15a falls to cause the transistor 15a to become OFF, and a voltage V4 becomes 0. Since the voltage of a drive circuit becomes 0 in this manner, even if a controller outputs a signal, the semiconductor switching element of an inverter does not operates. Since a photocoupler 15e generates at its emitter a protection signal of L level, it can output a protected signal. When a heat detection switch 7 is opened, the transistor 15a is also turned OFF.
