IPC: H03F1/34
Filed: 1989-06-20
Abstract: PURPOSE:To omit an electrolytic capacitor for coupling for cutting a DC voltage required for an input terminal and to prevent malfunction due to a defective electrolytic capacitor occurring by changing the input terminal to the one of GND reference input type. CONSTITUTION:In circuit configuration for an amplifier circuit A1, the input terminal A is changed to the one of GND reference input type, and the electrolytic capacitor for coupling for cutting the DC voltage required for the terminal A in a conventional circuit can be omitted. Therefore, an input circuit formed with of a seventh transistor Q7, a diode D1, and a constant current I4 performs the shiftup of the DC voltage for a normal sound signal inputted to the terminal A with a diode D7 via the emitter-follower operation of the Q7, and transmits a signal to the Q1 of the transistors Q1 and Q2 comprising a differential pair, and also, the base bias voltages of the Q1 and Q2 can be decided with the Q7 and the D1. In such a way, it is possible to prevent the malfunction due to the defect of the electrolytic capacitor.

Title: Semiconductor light-emitting element and manufacture thereof
Inventor: YAMAMOTO TAKAYUKI
IPC: H01S5/20
Filed: 1995-06-26
Abstract: PURPOSE: To integrate a spot size converter without etching an active layer by a method wherein the active layer, which becomes a resonator, is provided in a groove pinched by two current constriction structures, the layer of the same structure as the active layer is present on the current constriction layers, and the layer thickness of the active layer is gradually decreased from the middle part of the resonator towards the light-emitting end. CONSTITUTION: Before formation of an active layer, a current constriction structure 2 is formed on both sides of the part where the active layer is formed on the board 1, and a current flowing part is formed in groove shape. Then, film thickness can be distributed in the direction of a resonator on the current constriction structure 2. A mask 32, with which window width is changed, is selectively grown. By the growth of an active layer 3 and an upper clad layer on the mask 3, an active layer 3, which is recessedly bent, is formed and its thickness gradually becomes thin as going to the light emitting end in resonance direction. As a waveguide becomes thinner toward the light emitting end, spot size becomes large by the principle of diffraction, and the coupling with fiber is facilitated.

IPC: H04N5/66
Filed: 1994-06-17
Abstract: PURPOSE:To obtain the correction circuit for horizontal cross distortion in which sure clamping action is obtained with small power without increasing the capacitance of a charge/discharge capacitor. CONSTITUTION:As a charging current Ich is obtained at a portion where a pattern tends to be shifted to the right while a discharging current Ids is obtained at a portion where a pattern tends to be shifted to the left, one terminal of a capacitor 13 is grounded through a clamp diode 14 or a clamp transistor(TR) 15 without failure at the point of time of each of tips of parabolic waves. Thus, a clamp action is always produced for each horizontal blanking time and a parabolic voltage Vs2 across the clamp diode 14 is not floated positively, resulting that a horizontal deflection coil current Iy is made stable thereby suppressing horizontal cross distortion of an image.
