Title: Superconducting electromagnet device
Inventor: IWAHANA TAKEHIKO
IPC: H01F6/00
Filed: 1981-12-24
Abstract: PURPOSE:To shorten the time required for excitation and demagnetization, by detecting the magnetic field of a superconducting coil, and controlling the output current of a power unit so that the intensity of the magnetic field changes  at a predetermined rate of change. CONSTITUTION:A magnetic field detecting element 21 for detecting the magnetic field generated in a superconducting coil 2 is provided in a cryostatic container 1. The output of the element 21 is supplied as a control signal Z for a DC power unit 23 through  an amplifier 22 provided outside the container 1. When a signal P representative of the starting of excitation is introduced, the output current of the unit 23 is increased so that increase rate of the signal Z equals to the current increase rate determined by the characteristics of the coil 2. On the other hand, when a signal Q representative of the starting of demagnetization, is introduced, the output current is decreased so that the decrease rate of the signal Z equals to the current decrease rate determined by the characteristics of the coil 2.

Title: Recording and reproducing device
Inventor: EIKI YUJI
IPC: G11B20/02
Filed: 1991-08-27
Abstract: PURPOSE:To improve an operability by automatically recovering the switch connection condition prior to an erasing operation after executing the erasing operation so as to perform a recording immediately after the erasing operation. CONSTITUTION:When the track, to which a recording were to be performed, is already recorded, an erase standby.switch is pushed to erase the track.

IPC: H03B5/02
Filed: 1984-10-15
Abstract: PURPOSE:To generate many signals of different frequency at optional interval of time with reduced circuit scale by providing a variable capacity element and a voltage generating circuit which generates a voltage varying stepwise at specific time intervals and applies the voltage to the variable capacity element. CONSTITUTION:An LC oscillation circuit 1 is provided with a varicap 2 instead of a capacitance element C. This varicap 2 varies in electrostatic capacity C with an input voltage. Further, a voltage generating circuit 3 which generates a voltage V varying stepwise at specific time intervals is provided as the input voltage source of the varicap 3. When a time interval is t1, the circuit 3 generates a voltage V1 and then the circuit 1 outputs a signal of frequency f1. Then, when the time interval is t2 and a voltage V2 is 2V1, a frequency f2 is 2<1/2>f1. Similarly, when the voltage varies so that V3=3V1-Vn=nV1, the output frequency varies so that f3=3<1/2>f1-fn=n<1/2>f1. Consequently, a signal of optional frequency is generated for an optional time by constituting the circuit 3 properly.
