Title: Output buffer with voltage withstanding characteristic
Inventor: MORRIS BERNARD LEE
IPC: H01L27/04
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide an output buffer with a voltage withstanding characteristic. SOLUTION: An output buffer, consisting of an integrated circuit has an improved voltage-withstanding characteristic with respect to a voltage level higher than a power supplying voltage level designed for the operation of the integrated circuit. AP-channel transistor(TR) is typically adopted for a 1st transmission gate TR110, which is connected between a resistor 108 connecting to a node 114 and an output conductor 101. The node 114 is connected also to the gate of a 2nd transmission gate TR105 that is typically a P-channel TR. Since a resistor 108 boosts the level (e.g. ground level) of the node 114 to the power supply voltage level, the 2nd transmission gate TR is energized in the normal operation. In order to prevent the node from reaching the ground potential, voltage drop devices 201, 202 consisting of at least one diode are connected in series with the resistor.

IPC: H01M4/26
Filed: 1990-01-12
Abstract: PURPOSE:To make the thickness of a nickel plating layer uniform by impregnating an active material with water which active material comprises mainly a cadmium compound of a hoop shape applied on an electricity conductive core member, and subjecting the active material to electrolytic plating under the condition of the active material containing water. CONSTITUTION:Ethylene glycol solution of polyvinyl alcohol is added to powder of cadmium oxide and mixed and kneaded to make paste. The paste is applied on a hoop shaped core steel plate plated with nickel having an opening and dried to obtain an electrode plate. The electrode plate is immersed in a solution of phenoxy ascetic acid in the solvent of water and ethylene glycol, dried, impregnated with water, and subjected to electrolytic plating in a plating liquid containing nickel sulfate and boric acid to form a nickel plating layer on the surface. After the plating the product is immersed in a solution of magnesium sulfate, formed in potassium hydroxide, water rinsed, and dried to obtain a negative electrode plate. In this way the cadmium negative electrode of a paste type is provided with improved absorption on the negative electrode of oxygen generated at the time of charging.

IPC: H02G3/16
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To provide the bolt structure of a low production cost and light electric connection box. SOLUTION: An electric connection box 1 comprises a cover 2 made of resin; and a wiring board 3 on which a given circuit is formed through arrangement of a bus bar 4. A bolt part 5 is integrally formed on a base cover 2 made of resin through molding. Further, an insertion hole 6 through which the bolt part 5 is inserted is formed in the wiring board 3 and a connection part 8 is formed by exposing a part of the bus bar from the peripheral edge of the insertion hole 6 on the terminal mounting surface side of the wiring board 3.

Title: Filter circuit
Inventor: MURATA IKUO
IPC: H03H7/01
Filed: 1982-01-18
Abstract: PURPOSE:To prevent distortion through variation in resonance frequency by connecting a series resonance circuit including a varactor diode between a signal path in the wide-ban BPF of a converter tuner for cable television and an earth point and applying a channel selection voltage to the diode. CONSTITUTION:A trap circuit 4 is connected between the earth point and signal path between the wide-band BPF2 formed in the input circuit of the converter tuner for cable television and a nonlinear circuit 3 such as a frequency converter.

Title: Logical circuit simulation system
Inventor: MINAGAWA TATSUYA
IPC: G06F17/50
Filed: 1989-01-11
Abstract: PURPOSE:To make unnecessary the definition of all pieces of delay information and to easily prepare a delay defining file by attaining simulation and the detection of a glitch noise in the worst case. CONSTITUTION:An output register 5 supervises a response output 106 of an LSI 4, and when its output changes, the register 5 outputs time information after the activation of the simulation and a changed output 107. After access 108 is inputted, a delay defining file 6 outputs delay information 109. When the LSI 4 executes an operation which is not defined in the delay defining file 6, a value included in a changed output 102 is used instead of the delay information 109. An input state value storage memory 7 controls the input state value of each input pin of the LSI 4, inputs memory access 110, and outputs an input history 111 of the input pin concerned. Thus, the delay information defining file can be easily prepared.

Title: Rotary gear pump
Inventor: SAKAKIBARA AKIHIRO
IPC: F04C2/14
Filed: 1986-01-14
Abstract: PURPOSE:To prevent a gear from being worn and seizing, by providing a pressure introduction means for introducing the pressure of working fluid from an operating chamber into pressure grooves formed in both end faces of gears. CONSTITUTION:Working fluid is introduced into an operating chamber 20 in association with the rotation of both gears 1, 14, and a part of the fluid enters into pressure grooves 12a, 12b through pressure introducing passage 13. Pressure chambers 12a, 12b are communicated with each other through a pressure communicating passage 13, and therefore, the pressure thereof are equal to each other. Urging forces which are applied respectively to both gears 1, 14 by the pressure in the pressure grooves 12a, 12b, are also equal to each other, and therefore, both gears 1, 14 are held in a neutral condition while they continuously rotate without being biased toward either a front side plate 4 or a rear side plate 5. Thereby, it is possible to prevent the gears from being worn and seizing.

Title: Semiconductor storage device
Inventor: TANAKA HIRONORI
IPC: G11C11/418
Filed: 1982-01-20
Abstract: PURPOSE:To obtain a highly integrated semiconductor storage device which operates stably at a high speed by arraying a clamping diode at each boundary part between a column line driving circuit and a memory cell which uses a normally off type and a normally on type Schottky FET. CONSTITUTION:When the level at a terminal 708 of the column line driving circuit 705 rises, the normally on type Schottky FET709 is turned on and the FET710 is turned off through an inverter to select a corresponding column line 701 of a memory cell array 700. Then, a static memory cell using a normally off type Schottky FET which uses the column line 701 in common is selected. In this case, the clamping diode is arrayed at the boundary part between the driving circuit and memory cell and the potential at the column line 701 having started rising in level is clamped to a prescribed low level in a short time, so that a constant current flows to the ground through the FET709 and diode 706, but does not flow to the column line 701. Consequently, the rising is speeded up and potentials at respective parts of the column line 701 are made constant to obtain the semiconductor storage device which is integrated to a high degree and operates stably at a high speed.
