Title: Operational amplifier circuit
Inventor: IIDA TETSUYA
IPC: H03F3/347
Filed: 1978-02-13
Abstract: PURPOSE:To make it possible to obtain a stabilized output which does not cause any problem such as an oscillation by enabling a differential amplification state to DC-couple with a linear amplification stage stably. CONSTITUTION:The operational amplifier circuit consists broadly of constant- current supply bias circuit 1, differential amplifier circuit 2, offset compensator circuit 3, threshold-level matching circuit 4, and linear amplifier circuit 5. When both DC voltage levels of inputs in 1 and in 2 become high, those of outputs O1 and O2 of the differential amplification stage decrease, but circuit 3 functions at this time to prevent the variations in output DC voltage level of the differential amplification stage by the offset voltage of the kind. On the other hand, since circuit 4 prevents a difference between input-output characteristics of circuit 5 and the output voltage of the differential amplification stage regardless od DC levels of outputs O1 and O2, the DC voltage of output (out) of the operationsl amplifier is stabilized invariably. In addition, the amplifier parts cinsists of two stages, the differential amplification stage and linear amplification stage, so that oscillations due to phase lagging can be prevented.

Title: Reproducing device of rotary disk-shaped recording medium
Inventor: MIKI YUUJI
IPC: G11B21/04
Filed: 1983-01-31
Abstract: PURPOSE:To avoid a so-called locked loop phenomenon that produces repetitively the information of a rotary disk-shaped recording medium at the same position, by applying the bias voltage to a tracking coil and obtaining apparently a state where a housing precedes a stylus. CONSTITUTION:It is supposed that the signal fed from a phase compensating circuit 2 has voltage VA while a housing 8 is moving toward a reference mark 10. In such a case, the signal supplied from a processing circuit 12 consisting of a microcomputer, etc. applies the bias voltage VB to a feed motor driving circuit 5a through a control circuit 13. The voltage VB is larger than the output voltage VA of the circuit 12 (VB>VA). Therefore, the circuit 5a drives a feed motor 6 with the electric power equivalent to the voltage (VA+VB). As a result, the housing 8 moves toward the mark 10 and apparently ahead of a stylus 9.

Filed: 1978-02-14
Abstract: PURPOSE: To obtain an oil for roasting on hot plates having completely suppressed sputtering phenomenon, wherein oil drops fly away violently, without oil discoloration, by adding a specific amount of egg yolk lecithin to a liquid vegetable oil.  
     CONSTITUTION: A liquid vegetable oil is incorporated with 0.5W5 wt.% based on the oil of egg yolk licithin and, if necessary, an oleophilic food surfactant.

Title: Speed control circuit for motor
Inventor: SAWABE UICHIROU
IPC: H02P29/00
Filed: 1981-02-02
Abstract: PURPOSE:To inexpensively provide a control circuit by detecting the rotating speed of a motor with a magnet and a reed switch, thereby eliminating a tachometer generator. CONSTITUTION:When a motor 2 is rotated, a pulley 28 rotates at the speed proportional to the rotating speed, and a reed switch 32 is switched ON or OFF by a magnet 1. When the switch 32 is OFF, a current flows in the sequence of a diode 42, a capacitor 47 and a resistor 52, thereby charging a capacitor 47. Then, when the switch 32 is ON, a transistor 35 is conducted, and the voltage of the capacitor 47 becomes the emitter potential of the transistor 35. Thus, the cathode voltage of the diode 41 is varied in response to the rotating speed of the motor 2. When the rotating speed, for example, gets high, the cathode voltage is raised, and when it becomes higher than the potential of the divided voltage of the resistors 55, 56, the gate potential of a PUT 34 is raised, thereby reducing the voltage applied to the motor 2, and the speed is restored to the constant value.
