Title: Mercury contact switching device
Inventor: SENBA SHUNZO
IPC: H01H1/08
Filed: 1988-05-20
Abstract: PURPOSE:To make it possible to obtain a mercury contact switching device of a long service life by giving a specific size of difference in the intervals between plural movable contacts and a fixed lead. CONSTITUTION:Since the tip of a movable lead 2 is forked into two branches, and they have a difference in level to a fixed lead 4, two movable contacts 3 fixed to the respective parts have a size G of difference in level. The operation of the movable contacts 3 is driven by an electromagnet or an exciting coil provided outside. In the former period of the service life, the contact 3A closer to the fixed lead 4 of the two movable contacts is contacted to the fixed lead 4, and in the latter period of the service life when the mercury is scattered out by the friction, the movable contact 3B farther from the fixed lead 4 is contacted mostly to carry out the switching operation. In this case, the difference G in level between the movable contacts 3A and 3B is smaller than the height of the movable contact 3A. As a result, the shift from the movable contact 3A to the movable contact 3B to be contacted to the fixed lead 4 is performed while the abrasion and the scattering of the mercury of the contact 3 is not finished, and a long service life as the switching device can be realized.

Abstract: PURPOSE: To make it possible to use a load circuit for both DC and AC, by symmetrically connecting the load circuits which have used power insulating gate type field effect transistors, and controlling the gate in accordance with a current passing through the interface of the load circuits.  
     CONSTITUTION: A control signal corresponding to a reference signal is output to the gate terminal of the load circuits 1 and 2 in the operation amplifying circuit 12.

When the current flows into the resistor 4, the potential difference across it is output from the differential amplifying circuit 7, and it is input to the inverted input terminal of the operation amplifying circuit 12 through the absolute value circuit 8. When a current corresponding to the reference signal flows into the load unit, the signal applied to the inverted input terminal of the operation amplifying circuit 12 becomes equal to the reference signal applied to the noninverted input terminal, and a current flows into the load circuit 11 so that both of said signals can be balanced.

Title: Rotary drive controller of recorded disk
Inventor: HIRANO HIROYUKI
IPC: G11B19/24
Filed: 1980-09-08
Abstract: PURPOSE: To drive a recorded disk in a constant linear speed, by controlling both the period and inclination of a slanting signal in accordance with the number of revolutions of the recorded disk and the radius position of an information track and then controlling the number of revolutions of the disk based on the slanting signal.  
     CONSTITUTION: A frequency signal generator 2 produces a frequency signal (a) proportional to the number of revolutions of a disk 1. At the same time, a current source circuit 3 produces a current inversely proportional to the change of the radius (r) of the disk 1 by making use of a potentiometer and supplies the current to a trapezoidal wave generating circuit 4. The circuit 4 produces a trapezoidal wave, i.e., a slanting signal by a pulse train signal of the generator 2. This trapezoidal wave receives sample holding by the signal (a) and through a sample holding circuit 5. A differential amplifier 6 obtains the difference between the output V x  of the circuit 5 and supplies it to a driving circuit 7. The circuit 7 amplifies the output of the amplifier 6 to drive a DC motor 10. Thus the disk 1 can be turned in a constant linear speed and regardless of the radius (r) of the disk.
