Title: Semiconductor memory
Inventor: KANETANI KAZUO
IPC: G11C11/418
Filed: 1990-11-30
Abstract: PURPOSE:To increase the degree of integration and reduce the power consumption of a semiconductor memory by controlling the source potentials of memory cell driving MOS transistors to low levels when a bit line is selected and to high levels when the bit line is not selected. CONSTITUTION:The source potentials of memory cell driving MOS transistors M1 and M2 are not connected to current and voltage supply terminals, but respectively connected to column lines D1-Dn provided at every bit line. The potentials VE1-VEn of the column lines D1-Dn are controlled to low and high potentials by means of VE potential control circuits CC1-CCn which input Y- system address selecting signals VY1-VYn. A cell current IC starts to flow when the potential difference DELTAV becomes larger than the threshold voltages Vth of the MOS transistors and, as the voltage difference DELTAV becomes larger, a cell current IC also becomes larger. Therefore, the futile power consumption of this semiconductor memory can be prevented, since the potential difference between the potential at a word line and the VE potential becomes smaller and the cell current IC does not flow.

IPC: B05C11/08
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To form uniform film on the whole surface of a face panel by rotating a substrate and also generating, on the paint coated surface of the substrate, an air current going outward from the central part thereof. SOLUTION: This device consists of a cylindrical wall 8, a rotary supporting base 9 for supporting and rotating a cathode ray tube 1, and a paint feeding part 10. And, the bottom part of the device is provided with an exhaust opening 11 which is connected to an exhauster such as a fan. When the cathode ray tube 1 is fitted to the rotary supporting base 9 and the exhauster is operated, an air current 12 going downward from above is generated within the cylindrical wall 8. Since the air current 12 is prevented from going straight on by the cathode ray tube 1, it is turned into an air current of the direction along the cathode ray tube 1 around it. Therefore, on the surface (paint coated surface) of a face panel 2, the air current 12 going outward from the center thereof is generated. In such a state, paint is fed to the surface of the face panel 2 from the paint feeding port 10.

Abstract: PURPOSE:To prevent scattering loss of Cr raw ore and to enable reduction treatment at high speed by blowing gas from bottom blowing tuyere and side blowing tuyeres, blowing O2 from a top blowing lance and controlling charging speed of pure Cr. CONSTITUTION:Stirring gas of inert gas, such as CO or N2, is supplied from the bottom blowing tuyere 1 in a smelting reduction furnace to form rising part A on molten metal surface. At the same time, CO or inert gas is supplied from the side blowing tuyere 2 so that at least a part of gas flow collides to the molten metal rising part A, to scatter the molten metal rising part A. This scattered molten metal is diffused in range below the slag, which the Cr ore exists, and C in the diffused molten metal reduces Cr2O3. Further, the O2 for decarbonization is blown into the molten metal from the top blowing lance 3 and also the O2 for secondary combustion is blown into the slag. Then, the charging speed of the pure Cr is held to >=4kg/min ton of molten metal. By this method, the reduction speed of the Cr ore is risen and smelting reduction treatment is executed for short time.

IPC: G03G15/02
Filed: 1992-12-11
Abstract: PURPOSE:To enhance the glossiness in a short time without lowering the copying efficiency when a photographing mode is selected. CONSTITUTION:When a photographing mode 53 is selected in an image forming device, a press roller position control part 45 delivers an operating signal to a press roller position shift motor 40 which rotates an eccentric cam 26.

Title: Misfire detecting apparatus of engine
Inventor: MURATA MASARU
IPC: G01M15/00
Filed: 1987-12-28
Abstract: PURPOSE:To issue a misfire alarm at first when the misfiring states occur specified number of times, by judging the misfiring state based on the pressure difference between the maximum value of the internal pressure in a cylinder after a compression top dead center and the value of pressure at the compression top dead center. CONSTITUTION:A signal from a compression sensor 13 is imparted to an top-dead-center- pressure detecting means 20. A signal from a crack angle sensor 16 is supplied to a top-dead- center detecting means 21. The top-dead-center detecting means 21 imparts the detected signal of the position of the top dead center to the top-dead-center-pressure detecting means 20. Then, the top-dead-center-pressure detecting means 20 sets the pressure at the pressure top dead center. Then, a maximum-pressure detecting means 22 detects the maximum pressure value during the time a counter 23 counts the crack angles. Thereafter, a pressure-difference operating means 24 computes the pressure difference between the detected 20 pressure value at the compression top dead center and the detected 22 maximum pressure value. A pressure- difference judging means 25 compares the pressure difference with a specified value. When the result is less than the specified value, misfire or abnormal burning is judged. When that is repeated specified number of times, the misfire is judged with a misfire judging means 26, and the misfire is warned through a warning means (display lamp) 15.
