Title: Controller for electric rolling stock
Inventor: KIKUCHI KIYOSHI
IPC: H02P3/14
Filed: 1982-11-10
Abstract: PURPOSE:To enable to control a smooth current by detecting the current at the altering point at the regenerative brake time to control the instructed current value. CONSTITUTION:A pattern generator PD outputs a current value at the altering point as a current command IP until the altering point is detected by a current detector CD. When the altering point is detected, the current command IP is set so as to reach a normal value in approx. 1sec. A chopper CH controls the voltage supplied to a motor M in response to the deviation between the current command IP and a motor current IM. In this manner, a smooth current can be controlled, thereby reducing the variation in the torque.

IPC: G11B20/10
Filed: 1984-09-19
Abstract: PURPOSE:To modulate and demodulated correctly recording media in either case of the forward direction or reverse direction traveling by controlling the flow of data supplied to a modulating circuit and demodulating the flow of data supplied to a modulating circuit and demodulating circuit and the data outputted to the circuit according to the traveling direction of recording media. CONSTITUTION:Binary data of an input select an input terminal R or L of a two-way 3-bit shift resistor 1 by a switch which is changed over in relation to a changeover operation in the traveling direction of recording media such as a magnetic tape, and are inputted by a clock pulse CP1. Namely, when recording media is traveling in the forward direction, binary data are inputted from a terminal R and the data are shifted to the right, and when the media are traveling in the reverse direction, the data are inputted from the terminal L and the data are shifted to the left. As the result, a time before and after relation of outputs D0, D1 and D2 of the register 1 is kept fixedly regardless of the traveling direction of recording media. The output of the register 1 is supplied to a 3PM modulating circuit 3. Thus, even when recording media are in the traveling condition in either case of the forward direction or reverse direction, the media can be correctly modulated and demodulated.

Title: Monitor camera
Inventor: ATSUMI JUSAKU
IPC: G08B13/196
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To connect a lot of monitor cameras without increasing the current capacity of a power unit when the monitor cameras are serially connected to one power line. SOLUTION: A current limiting part 13 supplies a power source current, which is supplied from the power unit through a power line 4, while limiting it into prescribed current value. A charging part 14 performs charging on the basis of the current supplied from the current limiting part 13. Actually, it is better to limit the current from 20 mA to 30 mA. Power is ordinarily supplied from the charging part 14 to a main control part 12 but no power is ordinarily supplied to an image pickup part 10. When sending a video signal, the main control part 12 instructs the supply of power to the image pickup part 10 to a power source control part 15. According to this instruction, the power source control part 15 supplies the power from the charging part 14 to the image pickup part 10.  Thus, image pickup operation is started by supplying the required voltage and current to the image pickup part 10.
