Title: Manufacture of semiconductor device
Inventor: MIMURA TAKASHI
IPC: H01L21/306
Filed: 1979-09-07
Abstract: PURPOSE:To prevent the breakage of a wiring conductor by a method wherein the element forming region on a substrate having the principal ingredient of GaAs is masked and plasma-oxidized and by performing a heat treatment the height of the oxide film is decreased as far as it is almost in level with the bare surface of the element forming region. CONSTITUTION:An Mo mask is formed on a GaAs substrate 11 and an oxide film 13 is formed by oxidizing the exposed surface of the substrate in high frequency oxygenating plasma. Then the Mo mask is removed by employing plasma etching method to be used for etching CF4, an As2O3 in the oxide film is evaporated and the principal ingredient of the oxide film is changed to betaGa2O3, the height of the oxide film is decreased and the surface of the substrate 11 and the oxide film are almost in level with each other by performing a heat treatment at the temperature of 450 deg.C or above. Accordingly, an unlevelled section is not formed even when the oxide film is thickened and this produces no breakage of the wiring conductor and the semiconductor device with less parasitic capacity can be obtained.

Title: Load timer of electronic controlled distributing type fuel injection pump
Inventor: KOBAYASHI MASAYOSHI
IPC: F02D41/40
Filed: 1979-09-10
Abstract: PURPOSE: To improve output and exhaust characteristics by controlling injection time according to rotating speed and load change by operating a plunger type switching valve which is fitted between the high pressure side and the low pressure side of a fuel pump on the basis of the movement of a control sleeve which is slide- controlled by an electronic governor.  
     CONSTITUTION: When load of an engine is increased, a control sleeve 15 is pushed upward by controlling an electronic governor to increase fuel injection rate, and when the load is decreased, the control sleeve 15 is pushed down to reduce fuel injection rate. When the control sleeve 15 goes up or down, a switching valve 26 also goes up or down to open or close a passage 24. By designing the switching valve 26 so that it opens the passage 24 when the load of the engine is reduced and the control sleeve 15 comes to the lower end, fuel on a high pressure side of a fuel injection pump 10 is escaped to a low pressure side, and pressures in a pump housing 2 and a timer piston 7 go down, to reduce the timing rate at the injection time.

Abstract: PURPOSE:To apply high separability in a broad band to a stereo modulator by multiplying the differential voltage of signals at right and left input terminals with a carrier signal from a prescribed frequency signal generator, adding its output to the both right and left wave signals and the output of the signal oscillator at one half of the prescribed frequencies, and demodulating and outputting them. CONSTITUTION:The differential voltage of right and left signal input terminals 1 and 2 is multiplied by the carrier signal from a 38-KHz-signal generator 5 by means of a multiplier 3. The multiplier consists of a double balance type differential amplifier, and its inputs XA and XB can be directly connected to respective left signal input terminal 1 and a right signal input terminal 2. Further, since the output of the double balance type differential amplifier can be expressed in the form of the product of the differential voltage of the XA and XB inputs and the Y input signal, by using a sine wave from the 38-KHz- signal generator 5 for the carrier signal applied to the Y input, a carrier suppressed amplitude modulated wave excluding a higher harmonic can be obtained. Thus, a BPF can be omitted, and the high separability can be possessed in the broad band.
