Title: Semiconductor device and its manufacture
Inventor: FUJIMOTO HIROMASA
IPC: H01L29/41
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method capable of forming a high- performance power GaAs MESFET with a high yield at a low cost. SOLUTION: In a gate electrode forming process of an MESFET, a photoresist film 20 with an opening for a gate forming region is formed on an insulating film 21 deposited over an active layer 2. An opening is provided in the insulating film 21 with the photoresist film 20 as a mask, and a small recess region 31 is formed by performing a first recess etching for the active layer 2 with the insulating film 21 as a mask. Thereafter, the opening width of the insulating film 21 is widened leaving the photoresist film 20 as it is, a second recess etching is performed for the active layer 2, and a large recess region 30 is formed. Since a multistage region of more than 2 steps is formed by using one photomask, the production cost can be reduced. Also, each recess region and gate electrode 33 are formed in a self-matching form, both the yield and performance can be improved.

IPC: H05K13/04
Filed: 1989-09-05
Abstract: PURPOSE:To simplify the mounting of parts by using a printed-circuit board having the same pattern on both sides. CONSTITUTION:A multiple board has a first surface on which front and rear wiring patterns 1a and 1b are symmetrically formed corresponding to individual printed-circuit board 2', and a second surface on which wiring patterns 1b and 1a are symmetrically formed corresponding to individual printed-circuit board 1. The first surface of the board 2 is printed with soldering paste in selected locations. Electronic parts are positioned and soldered on the bored. The board is then flipped to mount parts on the second surface. Since the two surfaces of the board have the same structure and shape, the same printing masks can be used. Further, the same program is used for mounting electronic parts.

Title: Image data processor
Inventor: SATO TAKASHI
IPC: H04N1/04
Filed: 1986-09-30
Abstract: PURPOSE:To easily know whether a manual scanning speed is within a correct range or not and to prevent a read failure or a printing failure of image information by detecting the manual scanning speed, executing a notice by a buzzer, etc., at a time interval corresponding to the scanning speed. CONSTITUTION:When a handy copying machine body is moved in the read direction, an encoder pulse (f) whose period is varied in accordance with a moving speed is outputted in a speed detecting circuit 53. A multivibrator of a buzzer driving circuit 53a outputs a sound generating pulse signal (p) of a time width which is set in advance and an alarm sound buzzer 7a executes and alarm sound operation by a buzzer driving signal (q). When a reading and moving speed of the copying machine body is increased, the generation period of the encoder pulse (f) is shortened and an alarm sound operation interval of the buzzer 7a is shortened naturally. For instance, when the reading and moving speed of the copying machine body exceeds the maximum readable moving speed, the buzzer 7a becomes a continuous alarm sound state. In this way, an operator can easily know whether the speed is within a correct range or not by listening to the buzzer sound.

Title: Anti-skid control device
Inventor: TAKANO YOSHIYA
IPC: B60T8/48
Filed: 1991-09-12
Abstract: PURPOSE:To reduce and restrain low frequency pushing back kick-back force to a brake pedal accompanied by pressure reduction by repeating pressure boost and pressure reduction to each brake cylinder after the specified period of time has elapsed when reducing fluid pressure within each cylinder is kept on beyond the specified period of time. CONSTITUTION:When a condition of pressure reduction is continued beyond the specified period of time while an ABS is in operation, both pressure boost and pressure reduction are repeatedly controlled in a range beyond the specified period of time. In this control, control on information from wheel speed sensors 3a, 3b, 3c and 3d is executed by a controller 6 as a specified control process. If the specified quantity of brake fluid is released out of brake cylinders 2a, 2b, 2c and 2d, the pressure of the brake cylinders is lowered. Under a condition where pressure reduction control is continued, brake fluid lowered in pressure flows into a master cylinder 4 as rotary flow after the time for pressure reduction equivalent to the specified quantity, has elapsed. When there exists much rotary flow, it is turned out to be kick-back. In this case, the quantity of rotary flow is however controlled to be circulated within hydraulic units.
