Filed: 1989-06-29
Abstract: PURPOSE:To obtain a compact damping device by supporting a weight with a prescribed distance on the surface of a structure to be damped, and arranging linear motors in the two squarely crossing directions between the bottom face of the weight and the surface of the structure. CONSTITUTION:A weight 1 is supported on the floor face of a structure 2, keeping a prescribed distance (d) between.

Title: Liquid crystal display device
Inventor: KAMAGAMI SHINICHI
IPC: G02F1/1365
Filed: 1992-06-24
Abstract: PURPOSE:To provide a liquid crystal display device of high displaying grade with which no residual image phenomenon is generated by covering a signal electrode with a conductor, and preventing impurities such as citric acids to cause residual image from eluding from the positive electrode oxide film of the signal electrode to a liquid crystal layer. CONSTITUTION:A signal electrode 2 consisting of Ta and a lower electrode 3 of a MIM(metal insulation-metal) element part are formed on a base board 1 made of glass. On the surfaces of the signal electrode 2 and lower electrode 3, an insulation 4 of MIM element part is formed by positive electrode oxidation, and then a conductor 5 of chrome and the upper electrode 6 of MIM element part are formed, and thus the resultant MIM element 7 is configured with the lower electrode 3, insulation 4, and upper electrode 6. That is, the positive electrode oxide film over the signal electrode 2 is covered with the conductor 5. Because the covering layer is of conductive substance and connected electrically with the signal electrode 2 through the positive electrode oxide film over a wide area, no electric field is impressed in the positive electrode oxide film to prevent acting of any force which might promote elusion of impurity ions.

Title: Channel equipment
Inventor: SATO SHINJI
IPC: G06F13/12
Filed: 1987-07-02
Abstract: PURPOSE:To decrease the frequency of occurrence of data overrun in data transfer by counting the residual quantity of data in the data transfer by counting residual amount of data in the data transfer and giving the next data transfer request from a channel in precedence over when the count represents a predetermined value and a next data transfer request from the channel is given. CONSTITUTION:When a channel 2-i applies data transfer in the data chain processing and the residual byte count of a transfer residual byte count holding register 22-i reaches a prescribed value (m) or below for the detection and the next processing request from the channel 2-i is given, the processing request from the channel 2-i has precedence over the processing request from other channel. Thus, the interval from the data processing in the data chain processing till the next data transfer is reduced, then the frequency of occurrence of data overrun in the data transfer is reduced.

Title: Trochoid oil pump
Inventor: ISHIMATSU AKIHIRO
IPC: F04C14/28
Filed: 1998-05-30
Abstract: PROBLEM TO BE SOLVED: To mitigate a difference of oil pressure on a suction side and oil pressure on a discharge side and avoid generation of cavitation by providing an elastic means allowing an axial moving of an inside pump case in a high revolution area so that the inside pump case may be away from the sides of an inner rotor and an outer rotor by oil pressure. SOLUTION: In a low revolution area, an inside pump case 6 is urged to the sides of an inner rotor 14 and an outer rotor 16 by urging force of a coil spring 48 and a side clearance C1 is formed small. As a result, excess gaps are eliminated and deficiency of oil discharge amount is prevented. Because oil pressure within an oil pump 4 becomes high and the inside pump case 6 is axially moved against energizing force of the coil spring 48 in a high revolution area, the side clearance C1 becomes large, a difference of oil pressure on a suction side and oil pressure on a discharge side is mitigated and generation of cavitation is avoided.

Title: Mode setting circuit
Inventor: ITO KUNIHARU
IPC: H03K19/00
Filed: 1989-06-27
Abstract: PURPOSE:To set a large number of modes using a reduced number of terminals by mounting a plurality of charge/discharge circuits with different time constants performing charge and discharge by an input signal, a sense circuit for detecting the output levels of said circuits and a trigger FF inputting the output of said sense circuit to a decoder. CONSTITUTION:Charge/discharge circuits 24, 25 having different time constants performing charge and discharge by a input signal 1a' inverters 7, 14 detecting the output potential levels of said circuits 24, 25 and trigger FFs 8, 15 inputting the outputs of the inverters to a decoder 16 are mounted. When the signal 1a is an 'L' level, transistors Tr3, 10 are brought to a continuity state and connection points 6, 13 become an 'H' level and, when condensers 5, 12 are charged and the signal 1a becomes an 'H' level, transistors Tr 2, 9 are brought to a continuity state and the condensers 5, 12 are discharged. During the time when the signal 1a is the 'H' level, the trigger inputs of the trigger FFs 8, 15 can be arbitrarily generated based on whether the potentials of the connection points 6, 13 are sufficient to perform discharge up to a threshold value reversing the inverters 7, 14 and arbitrary mode setting signals 17-20 can be generated from the decoder 16. By this method, a large number of modes can be set by an extremely reduced number of terminals.

IPC: C22C21/10
Filed: 1981-10-20
Abstract: PURPOSE: To obtain an Al alloy for a bearing with high mechanical strngth at ordinary temp. and high temp. and superior wear resistance by adding Zn, Si and Cu as essential components to Al and further adding one or more among Mn, Cr and Zr.  
     CONSTITUTION: This alloy consists of, by wt., 3W10% Zn, 2W6% Si, 0.5W1.0% Cu, one or more among 0.05W0.6% Mn, 0.05W0.3% Cr and 0.05W0.25% Zr, and the balance essentially Al. The lower limit or more of Zn is required to obtain necessary strength and wear resistance, yet more than the upper limit of Zn tends to cause stress corrosion. The lower limit or more of Si is required to enhance the wear resistance and strength, yet more than the upper limit of Si provides excess brittleness and hardness and deteriorates the workability. The lower limit or more of Cu is required to enhance the strength and wear resistance, yet more than the upper limit of Cu deteriorates the corrosion resistance remarkably. Each of Mn, Cr and Zr has an effect of preventing the recrystallization of the alloy, yet less than the lower limit of it does not produce the effect sufficiently, and more than the upper limit of it tends to form coarse proeutectic during ingot making and causes embrittlement.

Title: Socket for discharge lamp
Inventor: HIRAI HIROKI
IPC: F21S8/10
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To certainly prevent a short circuit caused by an arc discharge between socket terminals when a bulb is not connected, with a compact structure. SOLUTION: This socket connects a light emission part of a discharge lamp to a power supply with the socket connected to a bulb 210 of the discharge lamp. A high-voltage side socket terminal and a low-voltage side socket terminal 34 are installed in housings 20, 30 of the socket.
