Title: Semiconductor device and its manufacture
Inventor: MATSUDA HAJIME
IPC: H01L29/812
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of the gate resistance of a semiconductor device even when the gate width is reduced, by forming a low-resistance layer and a stress relieving layer in eave-like shapes against a Schottky electrode. SOLUTION: After an n-type layer 9 is formed on an semi-insulating GaAs substrate 8 by Si ion implantation, etc., a Schottky junction layer 10 is formed on the layer 9. Then an n<-> area 12 is formed by performing ion implantation by using the junction layer 11 as a mask and side-wall oxide films 11 are formed on the side walls of the junction layer 10. After the oxide films 11 are formed, N<+> areas 13 are formed by performing ion implantation by using the junction layer 10 and oxide films 11 as a mask. Then, after a film stress relieving layer 14 and a low-resistance layer 15 are successively formed on the whole surface, heat treatment is performed for activating the areas 12 and 13, and the layers 14 and 15 are patterned on a gate electrode so that the widths of the layers 14 and 15 may become broader than that of the gate electrode and narrower than those of the oxide films 11.  At the time of patterning, the layers 15 and 14 are etched by using the oxide films 11 as etching stop layers. Finally, an ohmic electrode 16 is formed on the area 13 by vacuum evaporation.

Title: Seat vibration device
Inventor: FUKUOKA MASAHIRO
IPC: B60N2/02
Filed: 1991-06-08
Abstract: PURPOSE:To effectively prevent sleeping drive by providing a plurality of connection pieces downwardly extending from under a base and connected to a drive coil via communication holes. CONSTITUTION:A connection piece 22 downwardly extends, under a base 5, from a position corresponding to a communication hole 21, and this connection piece 22 is connected to an annular drive coil 23 by passing through the communication hole 21. When a switch on a control panel is turned on, a direct current is caused to flow into exciting coils 13, 14 to form a d.c. magnetic flux. As a result, an alternating current flows into the drive coil 23 in such a manner as to intersect this d.c. magnetic flux at a right angle thereto. For this reason, a vibrating force acts with the result that a seat 1 vibrates in the vertical direction. Accordingly, when a driver becomes somewhat sleepy, he can vibrate the seat 1 by turning the switch on and therefore becomes free from sleepy condition, thus enabling completely zeroing an accident attributable to sleeping drive.

Abstract: PURPOSE: To improve the processing performance and economy of a microprogram controller by performing switching by comparing the contents of a microinstruction address register with those of a trap register and by trapping the device when the comparison result shows identity.  
     CONSTITUTION: When the execution state of instruction A is to be investigated by setting a trap at address S 1  where instruction A is executed five times and its subroutine is executed ten times, the output signal of microinstruction address register 11 is compared with that of selector 17 in terms of address A 0  and when the frequency in coincidence agrees with value "5" in coincidence frequency assignment register 20, selectors 17 and 22 are changed over, so that address S 1  in the 2nd trap register 16 and frequency "10" in the 2nd coincidence frequency assignment register 21 is newly set values. Similarly, as a coincidence check is made ten times, a trap signal is sent via line 62 to stop the device. Thus, the instruction execution state of every step can be checked.
