Title: Distribution reflecting type semiconductor laser having tuning and requency-modulating mechanism
Inventor: SUEMATSU YASUHARU
IPC: H01S5/0625
Filed: 1980-02-20
Abstract: PURPOSE:To make it possible to arbitrarily tune and frequency-modulate the frequency of a semiconductor laser which oscillates at a single frequency by applying a voltage across both sides of the waveguide layer for output in order to vary the refractive index thereof. CONSTITUTION:In the distribution reflecting type laser; of the light emitted from the gain medium portion 10, only the light having the specified frequency determined by the grid cycle of the distribution reflectors 20 on both sides thereof is reflected, and of said light, only the light having a specified frquency is socillated as an output light. Said frequency is determined by the equivalent reflective indexes of the gain medium portion 10 and the reflector portions 20. Therefore, the oscillation frequency can be arbitrarily varied within a certain range by applying an external voltage from an external signal voltage source 25 to the reflector portions 20 to form a depletion layer in the ouputting waveguide layer 14 and varying the reflective index of the layer 14 by the electric field produced at the time. In this case, the oscillation frequency can be tuned to a desired frequency by a DC voltage V0. Thereby, frequency modulation can be effected by superposing an AC voltage V1 thereon.

Title: Thermister thermometer
Inventor: HANAOKA TADASHI
IPC: G01K1/02
Filed: 1982-02-09
Abstract: PURPOSE:To enable easy switching of centrigrade temperature display and Fahrenheit temperature display, by constituting a thermometer into a system in which a change in a resistance  value of a thermister serving as a temperature sensor is converted into a change in the number of oscillating frequencies of a CR oscillating circuit. CONSTITUTION:If a control signal G is applied to an input terminal P1 of a CR oscillating circuit 6, a pulse signal F1 is outputted from an output terminal P2. A variable frequency-dividing  circuit 7 divides the signal F1 in a frequency-dividing ratio Kf determined by receiving a frequency-dividing ratio assigning signal x to output a pulse signal F2. A frequency-divider 11 for  switching sensitivity divides the signal F2 by means of either of 2 types of frequency dividing  ratios KC and KF determined by a unit selecting signal U to output a pulse signal F4. In case  a measuring unit is 0.1 deg.C and 0.1 deg.F, the frequency dividing ratios KC and KF are brought to 1/9 and 1/5, respectively, and in which case, it is brought to a simplest circuit constitution. In case a centrigrade temperature is measured, 4 signal switching circuits are closed to a contact PC  side by means of the signal U. This enables a temperature counter 12 to forward in a 1 deg.C unit, and an address counter 10 to forward in a 5 deg.C unit. In case a Fahrenheit temperature is measured, the 4 signal switching circuits are closed to a contact PF side by means of the signal U.  This allows the temperature counter to forward in a 1 deg.F unit, and the address counter 10 to  forward in a 9 deg.F unit or a 5 deg.C unit.

Title: Protective relay apparatus for transformer
Inventor: HATADA MINORU
IPC: H02H7/045
Filed: 1978-02-21
Abstract: PURPOSE: To eliminate mulfunctioning otherwise caused by inrush current while free from second harmonic wave when encountering internal trouble by actuating the second harmonic wave control circuit within a specified time requiring a countermeasure against inrush.  
     CONSTITUTION: This utilizes the nature of the transformer that inrush is generated only when the voltage of the transformer exceeds a certain value as does at the start thereof. The voltage is detected with a voltage detector 1. The output thereof is applied to drive a one shoot multi-vibrator 12 thereby allowing the output V 8  of a second harmonic wave detection circuit 8 to pass through a gate. The output 8 is inputted to an inhibit circuit 9 to lock the output V 6  of a ratio differential relay. In this manner, mulfunctioning of the transformer protective relay due to the inrush current can be prevented. On the other hand, since the power of the transformer lowers whenever any internal trouble occurs, the voltage detector 11 provides no output. Thus the output V 8  of the harmonic wave detection circuit 8 is refused to pass through the gate, so that the protective relay operates normally.
