Title: Phase shift circuit
Inventor: SHIBUYA KENICHI
IPC: H03H11/16
Filed: 1987-07-30
Abstract: PURPOSE:To prepare only one external fitting terminal for a capacitor and to fit a circuit for the making of it into an IC, by obtaining a phase shift output signal from a division circuit or the connection point of first and second resistors by selecting the current ratio of first and second current sources and the resistance values of a first resistor and the resistor division circuit or a second resister. CONSTITUTION:The phase shift output signal whose gain is not changed by a frequency but whose phase changes can be obtained from the resistor division circuit R2 or the connection point of the first and second resistors R1 and R3 by selecting the current ratio of the first and second current sources 1 and 2 and the resistance values of the first resistor R1 and the resistor division circuit R2 or the second resistor R3. In other words, the addition of a constant voltage source can be realized because input is performed by current input, and the DC level of an output signal can be set arbitrarily. Since it is enough to connect one end of the capacitor to a common side, connection to a phase shift circuit can be performed by another end. Thus, in a case of performing the external fitting of the capacitor C, it can be performed only by one terminal, therefore. it is possible to fit the base shift circuit for the making of the circuit into the IC.

Title: Variable wavelength semiconductor laser
Inventor: INOUE NAOHISA
IPC: H01S5/06
Filed: 1981-11-27
Abstract: PURPOSE:To make the oscillating efficiency high, by forming comb shaped electrode ultrasonic wave oscillator on a light confining layer in an arc shape, and varying an oscillating frequency. CONSTITUTION:When an electric field of a frequency (f) is applied to the comb shaped electrode ultrasonic wave oscillator (IDT), a surface acoustic wave (SAW) is generated and propagated into the light emitting direction along the surface of a p type GaAs layer 3. Single vertical mode oscillation can be generated by said SAW. The laser light having the wavelength lambda is obtained by an expressionI, where the wavelength of the SAW is LAMBDA. When the frequency (f) of the applied electric field is varied, the DELTAlambda is obtained by an expression II, where V is the proparating speed of the SAW. When the oscillating frequency of the IDT10 is varied by DELTAf, the oscillating wavelength can be varied by DELTAlambda. Since the IDT10 is formed in the arc shape, the SAW is propagated in the converging direction. Even though the expansion in an angle THETA is considered, the SAW is propagated in approximately parallel, and the expansion of the laser light A is suppressed, and the oscillating mode is stabilized.
