Title: Magnetic tape storage device
Inventor: KAMISAKA ITARU
IPC: G06F15/02
Filed: 1982-05-28
Abstract: PURPOSE:To simplify the operation of a magnetic storage device for microcomputer, by providing a circuit flowing a minute current of a degree not operating a cassette tape recorder, and a comparator. CONSTITUTION:Although a switch 80 is opened normally with a command of a microcomputer 10, a minute current flows to an audio cassette tape recorder 40 via a resistor 90. Further, when all buttons of the recorder 40 are turned off and a button, e.g. a rewinding button is depressed, a consumption current flows to the recorder 40 and a potential of a power supply line l5 is decreased. As a result, a voltage comparator 100 discriminates that the potential is lower than a reference voltage, the microcomputer 10 recognizes which button is depressed, the switch 80 is closed and the power supply is applied to the recorder 40. Thus, the operation of the magnetic storage device for microcomputer is simplified.

Title: Nonvolatile semiconductor memory device
Inventor: HASUNUMA SUSUMU
IPC: H01L29/788
Filed: 1983-05-25
Abstract: PURPOSE:To enhance the rate of non-defectives by a method wherein a region through which a tunnel current flows in made narrow by providing a thinner insulation film in the periphery of a thin gate insulation film region. CONSTITUTION:A field oxide film 12 and a thin oxide film 13 are formed on the surface of a P type semiconductor substrate 11. An N type buried layer 14 is formed by ion implantation through this oxide film 13. Next, the oxide film 13 is removed, and the edge of the field oxide film of the buried layer 14 is removed at the same time. Then, on thermal oxidation, an insulation film 15 is formed on the buried layer 14, and a thinner insulation film 16 is formed at the part adjacent to the field oxide film. A floating gate 17, gate oxide film 18, and control gate 19 are formed. The tunnel current is strongly dependent on the field intensity, and so the current flows through the insulation film having a stronger field and thinner film thickness, in the presence of the insulation films 15 and 16 of different film thicknesses as gate oxide films in such a manner. Thereby, since the area of the thin gate oxide film region for the tunnel current can be controlled on the basis of the etching time of the oxide film, it becomes possible to form a narrow region into a thin film, thus enabling to enhance the reliability and the rate of non-defectives.

Title: Intercompliter data transmission system
Inventor: KAWAMURA SHIGERU
IPC: G06F15/16
Filed: 1986-04-23
Abstract: PURPOSE:To eliminate manual environment recognition and to prevent the loss of data transmission at the time of fault by permitting a computer on a receiving side to recognize its own environment at the time of data transmission and deciding the operation of a computer on a transmitting side in accordance with the condition. CONSTITUTION:At the time of data transmission, the computer A on the transmission side starts a program 5 controlling the transmission. The environment inquiry about the computer B is issued from the program 5 to a program 6 controlling the reception of the computer B on the receiving side. Thus, the program 6 starts a program 2 which recognizes its own environment, recognizes the environment of the computer B (the presence or absence of hardware fault, idle space quantity of a transmission data storage area) and transfers the result to a measure program 4. The program 4 issues a command to start transmission when the environment is adjusted, that to temporarily hold the transmission when there is a hardware fault, and that to stop transmission when data storage area is not enough to the computer A on the transmission side. It executes the issued instructions.

Title: Photomask
Inventor: TANIGUCHI HIDEAKI
IPC: G03F1/68
Filed: 1990-04-09
Abstract: PURPOSE:To prevent the generation of pattern defects of a substrate to be treated by the concentration of tensile stresses to pinholes and angle parts by forming effective patterns provided with roundness in the angle parts on both surfaces of a mask body. CONSTITUTION:A chromium film 2 is patterned and formed on the surface of the mask body 1 consisting of quartz or low expansion glass and the upper part is oxidized to form a chromium oxide film 3, by which the effective patterns 4 and alignment marks 5 are formed. A negative resist is applied on the rear surface of the body 1 and is exposed from the front surface side. This resist is subjected to development processing, etc. The roundness in the angle parts of this time effectively prevents the cracking of the resist. A chromium film is in succession formed and the regative resist is peeled to form the effective patterns 6. The probability that the pinhole positions of the respective patterns register each other is, therefore, extremely low even if the pinholes are generated in the patterns. The generation of the defects in the patterns of the substrate to be treated is thus prevented.

IPC: F24F5/00
Filed: 1988-04-14
Abstract: PURPOSE:To enable a healthy cooling without over-cooling with a less-expensive facility cost and a maintenance fee by a method wherein a roof and walls are thermally insulated with thermal insulation material, a radiator is arranged in each of spaces of a building in which an enclosing space and a garret space are communicated to each other so as to send a cold heat by an outdoor cooling machine. CONSTITUTION:An entire building is enclosed by a thermal insulation material 3. An under-floor space 6, an enclosing space 5 between a first floor and a second floor and a garret space 7 are communicated to each other with an inner wall space 4. A radiator 1 is connected with an outdoor cooling machine 2. In case that the radiator 1 is mounted at an enclosing space 5 between the first floor and the second floor as well as the garret space 7, a cold air from the radiator 1 descends in the inner wall space 4 so as to cool a room 8 from its ceiling or circumferences of walls. When the radiator 1 is installed in the space 6 or 5, the air within the space 4 may generate an ascending air flow vertically under an effect of chimney, a removal caused by a negative pressure at the garret ventilation port 10 or a forced pressure caused by a positive pressure at an under-floor ventilation port 9 and the like. Further, since a temperature of the under-floor space 6 is low, a more cooling with the radiator 1 causes the room 8 to be cooled from a circumference of the room.

Title: Welding method of ferrite system stainless steel strip
Inventor: SASAKI HIROAKI
IPC: B23K26/00
Filed: 1979-07-23
Abstract: PURPOSE:To prevent the degradation in the ductility and rolled characteristcs of the weld heat affected zone by limiting the quantity of welding heat input at less than the specific value by the use of a heat source of high energy density at the time of butt welding high chrominum content ferrite system stainless steel strips. CONSTITUTION:In butt welding the high chromium content ferrite system stainless steel strips containing chromium at >=16wt%, a heat source of high energy density such as laser or electron beam is used and the welding heat input allowing for the depth of welding is limited at <=15,000J/cm<2>. This makes it possible to effectively suppress the growth of the crystal grains in the heat affected zone. In order to control the components of the weld metal structure to austenite structure, a melt- sprayed film is beforehand formed on one or both of groove surface prior to welding. This is effective in terms of the close contact characteristic of butted surfaces and the uniformalization of the components of weld metal.
