Title: Formation of electrode wiring of semiconductor device
Inventor: FUJIMOTO TAKUMI
IPC: H01L21/28
Filed: 1986-06-04
Abstract: PURPOSE:To decrease contact resistance and to secure current capacity sufficiently, by performing anisotropic etching at the contact part of electrode wiring on the surface of a semiconductor substrate, and thereafter depositing wiring metal. CONSTITUTION:Anisotropic etching is performed at the contact surface of an N-type silicon substrate 1 and wiring metal before a metallic thin film is deposited. As anisotropic etching liquid, liquid, in which hydrazine hydrate (NH2NH2.H2O), isopropyl alcohol and pure water are mixed at a ratio of 60:6:22, is used. The silicon substrate 1 is etched for 10 seconds at a liquid temperature of 10 deg.C. Then not only a natural oxide film at a surface 10 (111) on the surface of the substrate is removed, but also regular-tetrahedron shaped etch pits 8 shown in the Figure are evenly formed. In this way, an electrode wiring having low contact resistance can be formed, by forming the etch pits in the contact part of the electrode wiring on the surface of the semiconductor substrate by the anisotropic etching and by increasing the contact area of the substrate and the wiring metal.

Title: Computer system and data expandor used in same
Inventor: MURAOKA KAZUHIKO
IPC: G06F12/04
Filed: 1995-05-29
Abstract: PURPOSE: To reduce the frequencies of readout from a main memory device and to increase processing speed by providing a data expandor which expands an intruction and data read out of the main memory device and returns them to original instruction and data. CONSTITUTION: An instruction group of instructions 1'-3' is obtained by data- compressing an instruction group of uncompressed instructions 1-3, and it is stored in the main memory device 6. When a processor 5 executes the instruction, a compressed instruction is transferred (data transfer 1) from the main memory device 6 to a code conversion control part 7, then, the expansion conversion of the compressed instruction is performed in the part 7. For example, the compressed instruction 1' is expanded to the original instruction 1. Moreover, an expanded instruction is transferred (data transfer 2) from the code conversion control part 7 to the processor 5. The processor 5 executes by receiving an uncompressed original instruction.  The data transfer 1 is performed at speed slower than that in the data transfer 2, and read-in is performed in the midst of the instruction 2' simultaneously, and the whole instruction 2 is read in by performing the read-in again.

Title: Control method of a/d converter
Inventor: MATSUOKA HIROKI
IPC: F02D41/24
Filed: 1983-07-15
Abstract: PURPOSE:To perform a proper A/D conversion in response to an operating state by deciding a signal system which performs an A/D conversion with preference and carrying out an interrupting A/D conversion for analog quantity delivered from said signal system when this system is suddenly changed. CONSTITUTION:The channel which performs the next conversion is decided in accordance with a schedule set previously within an ROM72, and a main routine is processed. Then A/D conversions are successively carried out in the order of the throttle opening, the throttle opening, the water temperature, the throttle opening, the intake-air temperature, the throttle opening and so on. Thus the A/D conversion is given again to the throttle opening when the throttle opening has first a sudden change. Then an A/D conversion is given to the water temperature in accordance with a prescribed schedule. Then the A/D conversion is carried out successively for the throttle opening in response to a sudden change of the throttle opening. Thus, the correspondence performance to control is improved.

Filed: 1986-06-06
Abstract: PURPOSE:To provide the improvement of the joint strength between porcelain and metal, etc., by investing a pattern preliminarily mounted with a porcelain molding by a molding material, then pouring a molten metal into the cavity formed by removing the casting pattern from the investing body. CONSTITUTION:The porcelain is preliminarily worked and molded by an atmospheric pressure sintering method, etc., to form the porcelain molding. The investing body of the porcelain-mounted casting pattern is fashioned by using the molding material. The casting pattern member for a metallic member is removed from the investing body to form the cavity. The cavity can be easily formed only by the heating of wax using a lost wax method, etc., in this stage. The desired molten metal is poured into the cavity and is cooled to solidify, by which the porcelain and the metal is joined. The molding material is removed. Since the influence of a heat cycle is eliminated by such method, the joint strength of the porcelain and the metal is improved and since the need for an intricate calcination stage is eliminated, the production cost is reduced.

Abstract: PURPOSE:To obtain information matching driving feeling, by sequentially lighting display segments which are provided continuously in correspondence with the speed of a vehicle, indicating the speed, and lighting the display segments before and after said segment in correspondence with the acceleration of the vehicle. CONSTITUTION:A vehicle speed sensor 1 outputs the pulse signal of a frequency which is proportional to the speed of a vehicle into a microcomputer 2, where the vehicle speed and the acceleration of the vehicle are computed. The vehicle speed and the vehicle acceleration are displayed on a bar-graph type fluorescent display tube 4. A display segment 41 at a specified position corresponding the present vehicle speed Vn is lit at high luminance, and the speed is indicated. When the vehicle speed is increased at a relatively small acceleration, the position of the high-luminance lighting of the display segment 41 is moved rightward in correspondence with the vehicle speed. Thereafter, the neighboring segments 41 on the left side of the display segment 41 are lit at gradually decreasing luminances. When the vehicle speed is increased at the relatively large acceleration, the lighting segments on the right side are increased. When the speed is decreased, the segments 41 on the right side of the high- luminance lighting position are lit at the gradually decreasing luminances by the number corresponding to the magnitude of the speed reduction.
