IPC: G11C29/00
Filed: 1988-11-28
Abstract: PURPOSE:To confirm the held voltage of all the memory cells and to obtain a high quality semiconductor memory by variably controlling read out control potential from the external terminal of the semiconductor memory applied prescribed connection with the respective cells. CONSTITUTION:A memory cell composed of transistors QR1 and QR2 of the semiconductor memory composed of a memory cell array and a read/write circuit as partially shown in a figure is selected, and write data are inverted, and signal terminals WDT and WDF are respectively set to high potential and low potential when this cell is under a holding state in which the cell never outputs information to a bit line. Further, when the potential of an external terminal VHC is gradually lowered, and the potential of a terminal RC, for which potential change corresponds to that of the VHC in the ratio of 1:1, is lowered accompanying the lowering of the potential of the VHC, the potential of the RC becomes lower than that of the WDT, QRT1 and the QWT1 are respectively switched to an ON state, and the holding state never changes. When the potential is further lowered, the cell is inverted at a point where the potential of the RC becomes lower than the base potential of a QH1. Here, the potential variation of the VHC is expressed as the held voltage in the cell. A data inverted state can be also grasped from the output waveform of a sense amplifier. The same processing is also executed for the other cells.

Title: Laser marking method for ceramic
Inventor: KONUMA YOSHIO
IPC: B41M5/24
Filed: 1987-11-27
Abstract: PURPOSE:To enable clear reading of marks through irradiation of an outer surface of a ceramic package with laser, by laser-marking the ceramic package after etching with chemicals being corrosive to the ceramic. CONSTITUTION:Nickel plating is applied to a metallizing layer constituting a wiring pattern on a surface of a ceramic package using an alumina ceramic colored black by the addition of chromium oxide or the like. A pin grid array(PGA) type ceramic package with external lead pins brazed thereto is subjected to etching. An etching liquid used here is, for example, a 10% aqueous solution of hydrofluoric acid, in which the package is immersed. Next, the package is neutralized with a 2% potassium cyanide solution, is rinsed, and is dried. An outer surface of the package thus etched is provided with a predetermined mark by irradiation with a laser beam using a YAG laser. The marking part thus formed has a high contrast against the black ground color of the ceramic constituting the package, ensuring clear reading.

Filed: 1987-11-27
Abstract: PURPOSE:To achieve electrical isolation between elements easily by a method wherein plateau-shape structures which have required faces are exposed on the surface of a group IV crystal substrate and then a III-V compound semiconductor layer is formed by an atomic layer epitaxial growth method. CONSTITUTION:GaCl and AsH3 are employed as group III raw gas and group V raw gas respectively and atomic layer epitaxial growth is repeated 2000 times on a wafer at 450 deg.C. The film thickness of a GaAs growth layer 19 obtained by slant polishing is, for instance, 7000Angstrom  on a face (211) and 4000Angstrom  on a face (110). AuGe ohmic contacts 20 are formed on four corners of the upper surface of each plateau-shape structure of the wafer. Electric conduction is recognized between the ohmic contacts formed on the same face (211) and, by a Hall measurement, the conductivity type is n-type and the carrier concentration is 1X10<16>cm<-3>. On the other hand, the electric conduction is not recognized between adjoining plateau-type growth layers so that the electrical isolation between elements can be achieved completely. Thus, the electrical isolation between the elements can be achieved easily without making a process complicated.

IPC: A47L19/00
Filed: 1988-11-29
Abstract: PURPOSE:To allow the drying degree of dishes to be uniform, to shorten a drying time and to improve operation convenience by providing a hot air blowing-out port in an upper direction rather than a water receiving board and providing a lot of bell-shaped hot air blowing-out holes over the whole surface of a heating plate, which partitions the water receiving board and a dish basket, for a hot air generating device. CONSTITUTION:When dishes 13 are dried, air sent from a fan 6 flows along the lower surface of a water receiving board 2 and is heated by a heat generating body 8. Then, the air goes hot air and is exhausted from a hot air blowing-out port 3 provided on the water receiving board 2 along the upper surface of the water receiving board 2. This hot air is temporarily closed in a space, which is sandwiched by the water receiving board 2 and a heat board 12 and spread over the whole space. After that, the hot air is uniformly discharged from a hot air discharging port 17 in a narrowed shape provided on the heating board 12 toward upper direction. When the discharged hot air passes through a dish basket 14, the dishes 13 are heated and stuck moisture is evaporated. Then, the hot air is discharged from the discharging port 16 of a cover body 15 to the outside of a dishwasher. The heating board 12 is heated by the hot air as well and by radiated heat from the heated heating board 12, the dishes 13 are further heated. Then, the evaporation of the moisture is promoted.

Filed: 1991-10-22
Abstract: PURPOSE:To minimize geomagnetic trapping and to obtain a large weak magnetic field space in a comparatively small case by a method wherein the cases formed of oxide superconductor which is turned superconductive at a point higher than a temperature of liquid nitrogen are made to overlap each other so as to form their walls of multilayer structure. CONSTITUTION:Paste is formed of Bi1.9Pb0.3Sr2Ca2Cu3OX superconductor powder previously put in a superconductive state. The paste concerned is applied onto the outer face of a silver cylinder whose one end is open, the silver cylinders are thermally treated for the formation of magnetic shielding cylindrical cases (11, 12, and 13). Non-magnetic materials are interposed between the formed magnetic shielding cylindrical cases (11, 12, and 13) to prevent the cases (11, 12, and 13) from coming into contact with each other, the cases (11, 12, and 13) are arranged at a regular interval in both a radial direction and an axial direction and installed in a cryostat formed of non-magnetic material, and liquid nitrogen is filled into the cryostat to cool. By this setup, the geomagnetic trapping can be reduced to a minimum, and a magnetic field noise source can be made very weak at the measurement of a very weak magnetic field.

Title: Input signal processor
Inventor: HASHIKAWA KENZO
IPC: G06F3/00
Filed: 1989-11-20
Abstract: PURPOSE:To eliminate the need for preparing a timer means and to make it possible to decide plural information by deciding the information of an input signal with the combination of output levels read out plural times from an input signal converting means. CONSTITUTION:One or plural kinds of 1st duty signals are generated by a duty signal generating means 3 synchronously with a clock signal generated from a clock signal generating means 2 and applied to the input signal converting means 4. The means 4 converts the inputted input signal into any one of one or plural kinds of 2nd duty signals based upon a high level, a low level or the 1st duty signal in accordance with the level of the input signal and outputs the converted signal. A reading means 5 for which a clock signal is applied reads out outputs from the means 4 plural times in accordance with the level of the 2nd duty signal and a discriminating means 6 discriminates the level of the input signal. Consequently, the timer means can be made unnecessary and plural pieces of information can be discriminated.

Filed: 1988-11-29
Abstract: PURPOSE:To read accurately a picture face of paper with various thickness by pressing a paper guide freely elevated and descended in a paper guide direction opposite to the guide by a spring force elastically. CONSTITUTION:A lower paper guide 8 made of a white shading plate supported freely elevated and descended is in elastic contact to the lower face of an upper paper guide 2 with a pressing spring 10 fitted to a device side while being kept in parallel with the upper paper guide 2. Moreover, the focus of an image sensor 4 is set onto the face of the paper guide of the upper paper guide 2. When the paper 28 is loaded between the upper and lower paper guides 2,8, the paper is fed in a prescribed direction while being in close contact onto the paper guide face, the distance with the image sensor 4 is kept constant and the picture face is located to the focus of the image sensor 4 and the picture face is read. Thus, the picture is read accurately in response to the thickness and width of the paper.
