Title: Manufacture of compound semiconductor crystal substrate
Inventor: NONAKA TOSHIO
IPC: H01L21/20
Filed: 1984-04-04
Abstract: PURPOSE:To enable the uniform formation of good compound semiconductor elements on an Si substrate by using a manufacturing method of absorbing the distorsion stress generating in a substrate by providing a section polycrystalline regions selectively. CONSTITUTION:A Ge layer 2 is evaporated as the intermediated layer over the Si substrate 1. At this time, the layer 2 turns into single crystal spontaneously by vapor-phase growth. Next, insulation film 3 are selectively formed in the part other than the region scheduled for compound semiconductor element formation on the layer 2. Then, a GaAs layer 4 is formed over the upper side of the films 3 and the layer 2 by the molecular ray epitaxial method, thereby changing the GaAs layer 4 on the layer 2 into a single crystal GaAs layer and the GaAs layer 5 on the film 3 into a polycrystalline GaAs layer. Distorsion stress generates in the crystal interface at every heat treatment during the above-mentioned manufacturing process; however, such a distorsion stress is properly absorbed by the layer 5 in the inactive region. Thereby, a compound active element 6 can be formed on the layer 4.

Title: Frame synchronizing pattern correlation detection circuit
Inventor: KOBAYASHI HIROKAZU
IPC: H04J3/06
Filed: 1986-03-26
Abstract: PURPOSE:To decrease the circuit constitution scale by using a frame synchronizing pattern generated at the reception side and a frame synchronizing pattern obtained from a received word to apply bit coincident numeral discrimination. CONSTITUTION:The frame synchronizing pattern SYCD is generated from a frame synchronizing pattern generating circuit 9 by using a start signal RPNS from a timing circuit 8 receiving a frame synchronizing signal FSYNC. The frame synchronizing pattern and the received word are fed to an exclusive OR circuit 10, where bits are compared. The output of the circuit 10 is fed to a frame synchronization bit coincidence counter 11 as an enable signal, a 4-bit coincidence signal A is outputted from the counter 11, which is compared with a preset 4-bit set number REF at a comparator 12. When set number < coincident signal A, an output from the comparator 12 is latched by latch circuits 13, 14 while matching the timing and a frame synchronizing pattern correlation detection signal CORR is generated from the latch circuit 14.

Title: Cleaning device of electrophotographic copying machine
Inventor: MORI IKUO
IPC: G03G21/00
Filed: 1984-04-03
Abstract: PURPOSE:To remove toner from a housing without leaving any toner in an air passage by making the flow rate of air fast through the operation of a slit passage and increasing the flow rate in the direction of the passage axis through the operation of a bar material. CONSTITUTION:The cylindrical air passage 8 which extends in parallel to a brush 3 is provided in the housing 2; one terminal of a thin slit 9 which extends to its overall length is open where the brush 3 is stored and the other terminal is open to the passage in a tangential direction. The round bar material 18 with a small diameter is arranged concentrically in the passage 8 and air flows in the passage 8 through the slit 9. The slit 9 is open to the passage 8 in the tangential direction, so an air flow which turns at a high speed along the peripheral wall 8a is generated and toner in the air is not deposited on the peripheral wall 8a. The air flows in the annular space because of the installation of the bar material 18 and the flow rate increases greatly near the peripheral wall 8a and also increases by the decrement in passage area because of the bar material 18. The outer peripheral part 3a of the brush 3 contacts the 1st and the 2nd flickers 10 and 11 to beat down toner sticking on the brush 3, and the toner is removed suctionally by the air.

Abstract: PURPOSE:To simultaneously remove an unnecessary part and to set a correct black reference level when an expanding reading is executed by providing a means to partially make the simultaneous scanning possible and a selecting/ prohibiting means to partially prohibit the simultaneous scanning. CONSTITUTION:At the time of an expanding reading, a transistor QZC to constitute a prohibiting means is turned off. In this condition, a shift register 105 is driven at a frequency fS by pulses phi1 and phi2 during the horizontal blanking period and a shading part ob1 is read. Then, 10 picture elements are not removed from the head of an unnecessary part (c) to an output line 103 because the transistor QZC is off. The shading part ob1 only is inputted to a processing circuit 104 and a black reference level is set by a clamping pulse CP. Continuously, at the next period, unnecessary parts (a) and (b) are removed at a frequency 2fS at a high speed. When a horizontal blanking period is completed and an effective period arrives, an expanding part (b) is transferred at a frequency fS/2 at a low speed.

Title: Processor
Inventor: IMORI HIROMITSU
IPC: G06F9/38
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To obtain a processor effectively improved in processing performance, by correctly estimating a branch solution direction from a branch history table. SOLUTION: In this processor provided with at least a branch history table, an instruction bit (H bit) is provided in a branch instruction. The H bit is set by a compiler when branch formation and its failure are estimated with high probability through the analysis, etc., of an instruction string to be executed. When a branch solution circuit 14 reports that the solution result of a branch instruction is erroneously estimated by the branch history table, information that is created by a BHT(branch history table) updating circuit 21 for H bit is registered in the branch history table without the H bit depending on the output result of the branch history table. With this, the branch history table correctly estimate a branch solution direction after that, and the processing performance of the processor is improved.

Abstract: PROBLEM TO BE SOLVED: To enable a disk name or a track name of a mini disk to be easily recorded in dubbing from a compact disk to a mini-disk and also in timer recording from a tuner to a mini disk. SOLUTION: With synchronous dubbing from a compact disk to a mini disk, if the mini disk is a blank one, the contents of the disk memo of the compact disk are copied, as they are, into the disk name of the mini disk. In addition, in recording the receiving signal from a tuner to a mini disk by timer recording, a recording start time is copied exactly in the track name of the mini disk, as are a recording completion time and a receiving station name all set by a timer. As a result, no inputting is necessary for a disk name or a track name.
