Title: External resonator type semiconductor laser
Inventor: KAMETANI MASAAKI
IPC: H01S5/0687
Filed: 1986-08-19
Abstract: PURPOSE:To keep the phase of returning light at the end surface of a laser in an optimum state, by providing a negative feedback means, wherein a part of a light output is converted into an electric signal, the signal is fed back to a laser oscillating means, and the oscillating state of said oscillating means is controlled. CONSTITUTION:Light, which is generated in a semiconductor laser 1, passes ring resonators 7-10. A resonance curve is formed in a photodetector 11. The peak value of the resonance curve is converted into a DC voltage in a peak holding circuit 13. When this voltage is deviated from a reference voltage 15, the difference is converted into a current. The current is injected into the semiconductor laser 1. The oscillating state of the semiconductor laser is changed by the injection of the current. The phase of the returning light at an end surface mirror 2 is changed. The series of operations offsets the phase change at the end surface mirror due to disturbance of an outer reflecting mirror 2. Thus the optimum state of the phase is maintained. In this way, the width of spectral line is fixed to a constant value corresponding to the reference voltage 15.

Title: Automatic heating apparatus provided with sensor
Inventor: UEDA SHIGEKI
IPC: F24C7/02
Filed: 1981-11-30
Abstract: PURPOSE:To ensure a stable automatic heating regardless of the amount of the object to be heated by a method wherein the time lapsed until the value detected by a gas sensor becomes a set value is counted and the set value is made variable in accordance with the counted time. CONSTITUTION:When the kind of the object to be heated is selected by operating the key on a keyboard 4, a control unit 9 sets an initial threshold value alpha0 corresponding to the depressed key. With commencement of heating, the control unit 9 renews the threshold value alpha0 with an output from an up-counter (not shown) and compares it with the level detected by a gas sensor 10. When the renewed threshold value alphan is exceeded, the control unit 9 outputs a HDT signal, interrupts the counting of lock of the up-counter and sets an additional heating time using the counted time. When said time period has lapsed, heating  is completed. This construction enables a stable automatic heating to be made regardless of the amount of the object to be heated.

Title: Protective circuit for field effect transistor
Inventor: NAKAMURA HIROSHI
IPC: H03F1/52
Filed: 1994-08-17
Abstract: PURPOSE: To prevent destruction by heating by arranging a resistor having a positive temperature coefficient at a part to be affected by heat generation and constituting the high potential side of the resistor voltage division circuit of a gate bias circuit by using the resistor. CONSTITUTION: When impedance on an output side is suddenly changed and the heat generation of an FETQ2 is rapidly increased accompanying it, the resistor R21 arranged inside the same chip as the FETQ2 which is a heat generation part is heated as well. Then, the resistor R21 becomes a high resistor by the heating. In this case, the temperature coefficient of the resistor R21 is positive and the resistor becomes the higher resistor as the temperature becomes higher. In the meantime, since the resistor R22 is arranged at the part outside or where temperature rise is less, the change of a resistance value is small. As the result, since the gate bias voltage of the FETQ2 determined by the voltage division ratio of the resistors R21 and R22 is shifted to a negative side and functions in a direction for lowering the current of the FETQ2, the heating in the FETQ2 is suppressed.  Thus, the destruction by the heating is prevented.
