Title: Method for growing compound semiconductor
Inventor: ONOZAWA SACHIKO
IPC: H01L21/205
Filed: 1987-03-25
Abstract: PURPOSE:To reduce the occurrences of the warpage of a water and of cracks when increasing the film thickness of the grown layer by using a plastically deformed Si substrate when growing on a Si substrate a compound semiconductor layer such as GaAs, thereby reducing the stress due to the difference in the thermal expansion coefficients of the Si substrate and the compound semiconductor. CONSTITUTION:On the rear of a Si substrate 1, a SiN film 2 is grown at a low temperature of the order of 300 deg.C by a method such as plasma CVD, thermal CVD or sputtering. Then, when this substrate is heated to a high temperature equal to or higher than about 800 deg.C, the SiN film is densified, whereby the Si substrate is plastically deformed convexly on the substrate side. Then, when the SiN film 2 on the rear of the Si substrate 1 is removed by HF or the like, the plastically deformed Si substrate 1 is not restored to the original flat state, but remains convex on the substrate side. On this plastically deformed Si substrate, a compound semiconductor layer 3 such as GaAs is grown using a MOCVD method while keeping the substrate temperature at 600 deg.C-750 deg.C, and the substrate is cooled to around the room temperature (25 deg.C), whereby a flat grown substrate can be obtained. With this, the warpage of the substrate doe to the growth of GaAs can be reduced.

Title: Differential amplifier circuit
Inventor: HONDA TAKASHI
IPC: H03K5/02
Filed: 1986-03-27
Abstract: PURPOSE:To reduce the current consumption and wiring capacitance and to prevent adverse effect attended with the fluctuation of a power voltage by adopting a depletion MOS transistor (TR) having a gate held at a ground potential for the lst MOS TR and outputting an output signal to an input signal with respect to a threshold voltage of the said TR. CONSTITUTION:In the depletion MOS 32, a drain current flows with a gate voltage zero and the gate voltage is connected to ground, then the current supply capability I depends on the control of a threshold voltage Vtd or the dimension W/L of the depletion MOS 32 as shown in the following equation: I=(W/L X 1/2)Vtd<2>. Through the constitution above, when an input address signal Ain is at an H level, the current supply capacity of the MOS 32 is lower than that of a MOS 31, aud when at an L level, it is kept higher than that of the MOS31. Thus, the absolute value of a threshold voltage Vtd of the MOS 32 is selected between the H and L level of the input address signal Ain. That is, the threshold voltage Vtd of the MOS 32 is used as the reference voltage to eliminate a conventional reference voltage generating circuit 13.

Abstract: PURPOSE:To make possible improving the quality of a picture including lots of information quantity by allocating a data quantity to a picture corresponding to information quantity which the picture has. CONSTITUTION:A prescribed video signal is inputted from a terminal 1 and first encoding is conducted in an encoding circuit 2. In result, generated data quantity D1 is stored in a storage circuit 3 at every short section. Then, the same video signal is inputted from the terminal 1 so as to conduct encoding. At this time, a target data setting circuit 4 successively transmits previously calculated target data quantity to the encoding circuit 2. The data quantity of the result in encoding at a second path is adopted as D3 so that total data quantity SIGMAD3 generated by the encoding result is detected by a total data quantity detecting circuit 5. The total sum SIGMAD2 of target data quantity D2 calculated at first is detected by a total data quantity detecting circuit 6. In a target data quantity correcting circuit 8, correction is conducted so as to increase generated data quantity at the time of SIGMAD2>SIGMAD3 and to decrease generated data quantity at the time of SIGMAD2<SIGMAD3.

Abstract: PURPOSE:To prevent assuredly the double insertion, by attaching a cover body at the place near the inserting port of a recording disk in a free rocking way, closing the cover body after detecting the state of insertion of the recording disk and opening the cover body only by inserting an empty jacket. CONSTITUTION:A lever 40 of a detector 38 turns counterclockwise with a spring 41 when a reproducer stores no jecket 6 nor holding matter 7. As a result, a slide bar 43 is pulled toward the detector 38. Thus a slide cam 44 of the bar 43 turns a lock frame 34 counterclockwise against a spring 37. Then both a cover body 3l and a cam device 32 turn counterclockwise to open a jacket inserting port. Under such constitution, the jacket 6 is stored into the reproducer to press the lever 40 clockwise. As a result, the bar 43 moves to the left and the frame 34 is released from the cam 44 to be turned clockwise with the force of the spring 37. At the same time, the body 31 covers the jacket inserting port.

Abstract: PURPOSE: To prevent the air-fuel ratio of the internal combustion engine from becoming overconcenterated by a method wherein the air from an air cleaner is introduced into a passage for discharging the fuel vapor component removed from an adsorbent through scavenging.  
     CONSTITUTION: An air feed pipe line 4 for introducing air into an element 23 of the air claner 22 is connected at the midway to a fuel vapor discharge pipe line 34 for discharging the fuel vapor into an air intake passage 28 of the engine from a canister 10.
