Title: Controller for copying machine
Inventor: ISHIZAWA HIROAKI
IPC: G03G21/00
Filed: 1981-09-17
Abstract: PURPOSE:To set a sheet of copying and to stop a copying machine quickly by stopping the copying machine under working according to the simultaneous operations of addition and subtraction keys for setting the number of sheets of copying. CONSTITUTION:During the copying operation when a copying start key 4a is turned on, the output of a control circuit 6 inverts to a high level and is applied via an inversion circuit; therefore, AND gates 7, 9 are closed, and the number of sheets of copying is not set despite operation of addition, subtraction keys 2a, 3a. On the other hand, when the keys 2a, 3a are turned on simultaneously during copying operation, the output of an AND gate 11 inverts to a high level via an OR gate 10 and is applied as a stop signal to a control circuit 8, by which the copying machine can be stopped quickly without providing any stop key. If the switches 2a, 3a are operated simultaneously when the copying machine is stopped by opening of the switch 4a, the high level output through the gates 7, 9 and an AND gate 12 is made into a reset signal, by which the number of sheets of copying is set quickly at one.

Title: Control device for transport facility
Inventor: HAYANO SHIROU
IPC: G05D1/02
Filed: 1979-11-09
Abstract: PURPOSE: To simplify the constitution of the control device, by transmitting both the call code and the control data to each cart using a frequency band.  
     CONSTITUTION: The bits a'We' are allotted of call time T 1  are allotted to the carts aWe, and both the call code and the control data to each cart are stored in each bit. Then the call bit is transmitted from the control device 22 of the ground side using a frequency band to be received by each cart and at one time. However only the cart corresponding to the call code gives an answer using another frequency band for the state data including the present address at that time point. At the same time, the control data transmitted is read to carry out its control. And the cart that decided that the call code is not for its own transmits no answer bit. In such way, the frequency bands to be used can be decreased, thus simplifying the structure of the control device.
