Title: Manufacture of semiconductor device
Inventor: TAKEDA SHIROU
IPC: H01L21/768
Filed: 1979-07-26
Abstract: PURPOSE:To enhance the moisture resistance of the semiconductor device and prevent oxidation of aluminum wires undesired by interpposing an alumina, chromina or titania layer to form a multilayer wire using polyimide group resin for an interlayer insulator. CONSTITUTION:The first aluminum layer 3 is formed on SiO2 film 2 on an Si substrate 1 formed with a semiconductor element. After alumina, chromina, or titania layer 4 is evaporated in approx. 0.01-1.0mu thereon, polyimide resin 5 is rotatably coated thereon, and is preliminarily cured in N2. Then it is perforated to each the alumina, chromina or titania layer of the opening, to completely cure the polyimide resin 5, to form the second aluminum wire layer 6 thereon, to then form an insulating layer thereon, perforate it, repeat the formation of aluminum wire layer, and finally age it at approx. 500 deg.C in N2. This configuraion can improve the adhesion of the polyimide layer to improve the water resistance of the water resistance of the device, to harden the polyimide resin, and to age the entire device. Accordingly, the aluminum wire layer may not be disadvantageously oxidized to form safely the semiconductor device.

Title: Semiconductor integrated circuit
Inventor: SUZUKI YUKIO
IPC: G11C16/22
Filed: 1993-04-21
Abstract: PURPOSE:To prevent the erroneous writing of unaimed data by making a program control circuit which outputs a write start instruction to execute a program only when the circuit detects a prescribed number of clocks required for issuing a program instruction. CONSTITUTION:A program control circuit 1 outputs a write start signal PGCY upon detecting the falling trigger of a chip select signal CS in an enable state. A clock number detection circuit 2 sets a signal KCOUNT to 'H' and the control circuit 1 to an enable state only when 16 pieces of clock signals which are required for a program are inputted. When the signal CS falls while the control circuit 1 is set to the enable state, the signal PGCY of the circuit 1 rises and the circuit 1 starts writing. However, when the number of inputted clock signals is not 16, but 17 or 15, the signal KCOUNT is 'L' and the signal PGCY does not rise. As a result, the circuit 1 is set to a write inhibit state. Therefore, the erroneous writing of unaimed data is inhibited.

Title: Double vacuum pressure forming machine
Inventor: ABE MASAHIRO
IPC: B29C43/02
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To manufacture a high quality formed product which is free from defects such as a bubble or the like at a low cost by a method wherein a pressure is reduced inside airtight space, the formed product is stuck fast to a forming support tool, air is supplied to an inside of the airtight space thereafter, and a semiformed product is pneumatically pressed. SOLUTION: A reinforcing material 41 such as a glass mesh sheet or the like is arranged as occasion demands to a forming support tool 10 formed so that, for example, a required design is obtained on a surface of an architectural design plate, and then a forming material 40 wherein an inorganic ordinary temperature hardening material is mixed with silica (an aggregate) is charged to impregnate a reinforcing material 41 therewith. After reducing a pressure of an inside of airtight space formed by closing a top cover 14 to a degree of 60-70 Torr, pneumatical pressing is executed at about 1.5-2 atm. Thereby, the highly reliable architectural design plate can be easily obtained at a high speed without any bubble.  Therefore a highly priced large size press machine and a mold are made unnecessary, and a large formed product such as a wall material or the like can be effectively manufactured at a low cost. Especially this method is suitable for manufacture of the architectural design plate of a concrete shuttering.

IPC: B23H7/06
Filed: 1992-03-21
Abstract: PURPOSE: To reduce the danger of wire electrode disconnection at an initial cutting stage by constantly varying at least some of reduced cutting parameter values until they reach cutting parameter values for actual shape cutting. CONSTITUTION: An introduction path 5 is provided in contact with a cutting start point 4. A wire electrode is advanced through the introduction path 5 along a cut groove by reduced power. Accordingly, specific cutting parameter values for cutting a workpiece 3 are increased continuously. After the wire electrode has advanced over a distance of desirably eight millimeters although the distance becomes rather short or long depending on the thickness of the workpiece 3 and other limiting conditions, the wire electrode is actuated by means of a cutting parameter value that generally corresponds to the parameter value for cutting the workpiece 3 at full power. The wire electrode reaches the start point of an actual cut shape 7 at the end point 6 of the introduction path 5.

Abstract: PURPOSE:To minimize a storage area by registering retrieved information including desired working information, reading the retrieved information from a data storing device, processing picture data and displaying, and thereby registering picture data to be magnified and reduced together with the original picture data. CONSTITUTION:Dot width in (x) direction of a window magnified and displayed is made x1, and dot width in (y) direction is made y1. Page control record 41 to be displayed is read from a retrieval information file and the extent of display in a CRT is determined for each magnification ratio 41b. For instance, in the case of magnification of two times, 2x1X, 2y1 dots are reduced respectively to 1/2 through a thinning circuit 14 to display picture data on an image memory 11 of 2x1, 2y1 dot width in the width of (x1, y1). At the time when magnification ratio is one time, for instance, the picture data of 16 dots/mm are displayed in the CRT 3 of 4 dots/mm based on the size 41a of the record. Accordingly, the result of reduction thinned once every 4 dots is transferred to a video memory 12. Thereby, the storage area can be minimized.

CONSTITUTION:A paste material is squeegeed using a squeegee 7, and the position of the squeegee 7 is detected by an encoder 9 and the detected data is output when a printing screen 3 is extended in a squeegee 7 movement direction by friction power. Then this output position detection signal enables a control device 10 to control the derive amount of a drive device 10. In turn, the intermediate part of a flexible rod 4 is driven in an opposite direction to the movement direction of the squeegee 7 in accordance with the position of the squeegee 7. Subsequently, the flexible rod 4 curves in a drive direction, and the printing screen 3 is pulled toward the drive device 8 along the flexible rod 4 together with a formed pattern. Next, the correction value of the printing screen 3 is set at a few points within the movement range of the squeegee 7 and the setting data is entered in the control device 10. As a result, a deformed pattern formed on the mesh of the printing screen due to position misalignment can be corrected during pattern squeegeeing process.
