Abstract: PURPOSE:To obtain a cooling plate having high durability by applying an Ni metallic layer and further Cr or Cr carbide layer on the outside surface of the cooling plate which is disposed on the inside surface of a shell and is designed to be passed internally with cooling water. CONSTITUTION:A layer 2 of Ni, Ni-Fe, Ni-P, Ni-W, Ni-Al, etc. is mounted on the top surface of a body 1 of a cooling plate made of copper or a copper alloy by means such as plating, melt spraying or the like.

Title: Output circuit with characteristic check function
Inventor: TAKEMASA HITOSHI
IPC: H03M1/10
Filed: 1991-06-26
Abstract: PURPOSE:To facilitate the confirmation of soundness of the circuit by adding a test signal to an input signal inputted to a D/A converter and changing the signal in an operating range of the D/A converter to measure an output data and to collect an input output characteristic data. CONSTITUTION:In the case of confirming an output when a D/A converter 4 receives a 0% signal, an arithmetic operation circuit 180 outputs a 0% simulation command signal S2 to a signal simulation circuit 11. The circuit 11 sets forcibly an input signal S3 of the D/A converter to 0% independently of the input signal S1. Since the signal S3 is set to 0%, the circuit 18 compares an output signal S4 of the D/A converter with a count with respect to the signal S2 to calculate the count error. Thus, the signal S4 is compared with the counter accuracy stored in advance to discriminate the acceptability of the operation of the converter 4. function the arithmetic operation circuit 18 stores the test data and outputs the result as a data output signal S7.

Title: Data highway device
Inventor: YAMAGUCHI HITOSHI
IPC: H04L12/437
Filed: 1983-08-24
Abstract: PURPOSE:To search double failures on a data highway rapidly by outputting a loop back command from a master station to a local station adjacent to the master station and sending transmission data to be sent to a signal line also to a loop back line. CONSTITUTION:When the signal line connected to the master station is disconnected, a loop back control part 5 regards a signal received from the local station through the loop back line as the received signal of the station concerned. A data receiving part in a data highway control part 8 detects that the received data are not transmitted from the master station, but are transmitted from the local station and writes control data indicating the existence of a fault in the control part 8. On the other hand, no signal is sent to the master station from the local station concerned and the control part 5 controls the local station so as to send the transmission data to the master station through the loop back line. A loop synchronization control part 7 in the master station outputs a loop back signal through command on the basis of the control data indicating the fault in the transmission data to form a loop by the loop back line.

Title: Semiconductor storage device
Inventor: OGUCHI AKIRA
IPC: G11C29/00
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To write a checker board pattern by writing at a time by providing a switch means for disconnecting a row decoder and a word line from each other by a test signal at the time of a test and a word line starting means for activating the word line by the test signal. SOLUTION: At the usual operating time, the test signal 10 is set to a low level. Therefore, since a switch circuit 20 is conducted, an output of the row decoder 3 is transmitted via the word lines 11 and the switch circuit 20 to each individual word line couple WLa 5 and WLb 6. Consequently, only one word line 11 is selected in accordance with an address signal 4, becoming an H-level. Therefore, a data is written in and read out of only a selected memory cell. At the time of the test, the test signal is set to a high level. Therefore, the switch circuit 20 becomes inactive, so that the work lines 11 and the WLa 5 and the word lines 11 and WLb 6 are electrically separated from each other. Then, a word line starting circuit 21 works to start up plural word line couples WLa's 5 and WLb's 6.

Abstract: PURPOSE: To prevent the reduction of the efficiency of energy consumption (EER) by communicating the intake chamber of a fixed scroll and a lubricating oil chamber with a pipe and providing a shape memory alloy spring controlling its switching valve.  
     CONSTITUTION: The intake chamber 12 of a fixed scroll 1 and a lubricating oil chamber 22 are communicated with a pipe 23, and its opening or closing is controlled with a shape memory alloy spring 24. The shape memory allow spring 24 is shrunk at the time of cold start, thus a gap is generated between the pipe 23 and a sealing valve 26, and lubricating oil 21 is guided to the intake chamber 12 by the pressure difference. The spring 24 is extended as the operation time elapses and the pipe 23 is sealed, but the viscosity of the lubricating oil 21 is low, and the lubricating oil flows into the intake chamber 12 through fine holes 2b, 2c and fed to a scroll sliding section. At the time of hot start, the pipe 23 is sealed, and oil is guided to the intake chamber 13 through the fine holes 2b, 2c. The oil feed to the scroll sliding section can be quickly performed, thus this is effective to prevent the reduction of the EER due to the mechanical loss such as abrasion.

CONSTITUTION:The power quantity is measured by a power quantity measure section 2 based on the voltage and current from a measure input terminal 1, and the meter signal corresponding to the power quantity is fed to a meter section 3. The meter section 3 divides the meter signal into time zones switched by the switching signals from a time zone switching signal generation section 6 for metering. The meter value of the meter section 3 is displayed on a display section 4. The switching signals for dividing the meter signal into the time zones are generated by the time signal of a clock section 5, the switching time set in the time zone switching signal generation section 6, and the time set in a time zone switching signal correction time set section 7. The set section 7 uses the shift time expected from the accuracy of the clock section 5 as the correction value, and the switching time of the switching signal is corrected so that the switching is invariably made in the time zone charging a lower fare.

Abstract: PURPOSE:To effectively prevent the internal reflected light generated on the inner surface of a panel by providing a protrusion consisting of glass fiber powder and thermosetting high polymer material on the inner surface of the panel. CONSTITUTION:High polymer material is dissolved in a solvent and is mixed with glass fiber powder. For example, the dissolved and mixed material is injected from a nozzle and the inner surface of a panel is coated with it by the spraying method. Then after the inner surface is naturally dried under clean atmosphere, it is heated and treated. The high polymer material containing the glass fiber powder is cured. As a result, the inner surface of the panel 1 becomes recessed and protruded by cured high polymer material 10 and glass fiber powder 11. These recesses and protrusions randomly reflect and diffuse the light that externally passes through the panel 1 and is incident on the inner surface.

IPC: H03K19/00
Filed: 1984-07-25
Abstract: PURPOSE:To obtain a memory circuit containing a tristate output circuit consisting of a small number of transistors by combining an inverter and a transfer gate. CONSTITUTION:An inverter 4 consists of FETQ11 and Q12; while a transfer gate 6 consists of FETQ13 and Q14 respectively. When a data output control signal D0E is kept at 1, both FETQ13 and Q14 are turned on. Thus the FETQ11 and Q12 are turned on and off or vice versa in accordance with the inverse phase data bus signal DB. Therefore a data output terminal DOUT is set at 1 or 0. When the signal D0E is set at 0, both FETQ13 and Q14 are turned off. Thus the terminal DOUT is put under a floating state regardless of the stage of the signal DB. As a result, a tristate output circuit of a memory circuit can be constituted with six transistors.
