Title: Shortening method for purge action time and image output device using the method
Inventor: OTAKE TAKAO
IPC: G03G15/00
Filed: 1994-01-28
Abstract: PURPOSE:To complete a purge action in a short time in response to the number and position of copying sheets by providing long and short timer means, and repeatedly operating the short timer means when a change occurs on either output of a detecting means in a short time. CONSTITUTION:When a start key 13 is pushed, a longest timer, a 5-sec timer, and all motors are turned on by the signal from a ROM 11, and a purge action is started. No change occurs on the outputs of all sensors regardless of the rotation of all motors because no copying sheet exists. When they are turned off after the 5-sec timer is turned on, an IOT CPU 5 judges that no copying sheet to be discharged exists and the purge action is completed. The longest timer and all motors are turned off without turning the 5-sec timer on. When the 5-sec timer is used in addition to the longest timer, the purge action can be completed in five sec.

And the values of the start address register 11 and the capacity register 10 are added by the adder 12. Next, the value added on the bus 7 for memory constitution is outputted, and simultaneously, indication to start constitution is issued to the memory card 3 by using the constitution start information line 8 for outputting. Such operation is performed on the memory cards 2, 3, 4, and 5 sequentially. Finally, a central processing unit 6 holds the output of the memory card 5 in a system memory capacity register 13. By reading the value, it is possible to recognize the memory capacity of the whole of a usable system.

Title: Perforation work device
Inventor: UMEZAWA MAKOTO
IPC: B21D28/04
Filed: 1981-01-26
Abstract: PURPOSE:To form holes in different shapes automatically at the circumferential wall parts of nearly cylindrical works, by treating the works on a bolster which is equipped with pierce punches and rotates intermittently. CONSTITUTION:Press working machines 12 for perforation are installed in stages S1-S6 at intervals of a constant angle alpha centering on a rotary shaft 15a. Nearly cylindrical works W to be perforated are moved successively from a carry-in stage S0 to the S1-S6 in a direction B. The stages S1-S6 are provided with button dice and pierce punches differing in shape to punch part of the circumferential wall of each work W. The work W rotates by the angle alpha and moves forward in the direction B to make a hole in a different shape in its contiguous circumferential wall surface. Thus, each work rotates by the angle alpha and moves forth to move the stage S1-S6, thereby making six holes over the entire circumferential surface. The completely perforated work is taken out of the stage S7.

Title: Readhering method of electric rolling stock
Inventor: KOO HIDEO
IPC: B60L9/18
Filed: 1983-01-20
Abstract: PURPOSE:To largely improve the rated controllability of an induction motor IM and a vehicle performance by reducing the input current control target value of the IM to the magnitude corresponding to an exciting current when the IM slips and returning it to the original control target value by the readhesion of a drive shaft. CONSTITUTION:A rotor current pattern IR of an IM is calculated and outputted by a rotor current pattern circuit 17 from a torque command T, and a slip or slide is detected by a switch 18, which is thus conducted. In other words, by detecting the slip or slide, a pattern IR is subtracted from the current pattern IP of the IM to follow up the reduction in the input current of the IM. Thus, the output of a comparison amplifier 12' does not vary. Accordingly, the increased of the output frequency of the inverter can be prevented. In this manner, the constant speed controllability of the IM can be provided, thereby largely improving the vehicle performance.

Filed: 1984-01-24
Abstract: PURPOSE:To obviate driving control at overspeediness and abnormal speediness in an engine, by comparing a detected engine speed with at least one of setting reference speeds and, when it satisfies the required specified speed condition, releasing the driving control. CONSTITUTION:An engine speed detecting device 11 for an engine speed and a control release device 13 which compares the engine speed with at least one of the setting reference engine speeds and outputs a control stop signal when it satisfies the required specific speed condition both are installed. And, when a car speed control device 7 controls a self-car speed by driving and controlling a throttle valve opening control device 9 on the basis of a car-to-car distance and the self-car speed detected by a car-to-car distance detecting device 1 and a car speed detecting device 3, if the said control stop signal is inputted into a controller, this self-car speed control is stopped. With this constitution, engine's overspeediness due to trouble in a clutch switch and/or slippage in a clutch plate as well as such driving control as being in a state of engine's abnormal speed based on wrong speed control due to trouble in a car speed sensor are all preventable.
