Title: External contact detecting circuit
Inventor: SAKAI SHIGEO
IPC: H01H9/54
Filed: 1983-12-05
Abstract: PURPOSE:To reduce the number of parts of an external contact detecting circuit which uses a photocoupler and to reduce the cost of by connecting the base and emitter of a phototransistor through a capacitor. CONSTITUTION:When an external contact 1 is broken, no current flows through a light emitting diode LED21, which does not turn on, so the phototransistor PTR22 is off and a voltage V3 is as high as the voltage of a power source 4, and amplified and outputted through an amplifier 11. When the contact 1 is made, the LED21 emits light, which is made incident to the base of the PTR22 to apply a forward bias voltage to the base. The capacitor C10 connected between the base and emitter of the PTR22 is charged with said bias voltage and then the current flows to the base of the PTR22, so the on operation of the PTR22 is delayed. The capacity of the C10 is so determined that the charging time of the C10 becomes longer than the chattering generation time of the contact 1, and the threshold voltage V4 of the amplifier 11 is set properly to compose the contact detecting circuit which is not influenced by the chattering at the contact 1 by using small number of parts.

Filed: 1990-08-31
Abstract: PURPOSE:To reduce the synchronization lock time by providing a phase comparison characteristic to a phase history discrimination circuit in which its output phase control voltage is a prescribed positive or negative voltage with respect to a synchronization stabilizing point.

Title: Focus control parts for optical recording
Inventor: KUNIDA SHINOBU
IPC: G11B7/085
Filed: 1983-12-06
Abstract: PURPOSE:To simplify the parts needed for focus control and at the same time to decrease the time delay of the focus control, by providing a lens function to a slider which can float up with shift or revolution of a recording medium. CONSTITUTION:A floating slider 8 incorporates a beam focusing lens 3' and the reflected beam given from an optical recording medium 7 arrives at a photodetecting element after passing through the lens 3'. The slider 8 can keep automatically a constant floating distance E from the optical recording medium. This distance E can be changed by controlling the form of the slider 8, the rigidity of a support part 9 of the slider 8 and the relative speed between the medium 7 and the slider 8. Thus it is possible to control the focus of the record signal with extremely small parts. Furthermore, the distance E can be controlled to the constant value by the slider 8 itself with no use of a complicated control circuit or a lens drive part. Therefore, it is possible to control a focal point assuredly despite the increase of the relative speed between the slider 8 and the medium 7.

Abstract: PURPOSE: To enable a stable supply of hypoxia mixing gas of a specific value of oxygen concentration. CONSTITUTION: A compressor 1 compresses normal pressure air in the air and supplies it for an oxygen separation part 3. The oxygen separation part 3 has a hollow string shaped membrane element 5 composed of polymethyl-4-penten.
