Abstract: PURPOSE:To obtain the titled sheet exhibiting an excellent adhesion to parts and a low connection resistance and capable of providing parts with high reliability, by alternately arranging in a sheet capable of thermal activation a first section comprising specific electrically conductive portions with a second section consisting of an adhesive only. CONSTITUTION:A thermal activation type of adhesive 41' having insulating properties which exhibits an excellent adhesion upon being heated and an electrically conductive portion 42' comprising an electrically conductive particle 12 of carbon, silver, solder, etc. densely incorporated therein and the adhesive in a minimum amount required are laminated and bonded on to of each other, to thereby form a raw material block 4' of which the thickness H is relatively large. The block 4' is passed through between a pair of pressure rolls 5, 5 having a predetermined space therebetween to obtain an electrically conductive adhesive sheet 4 having a desired thickness h and comprising a first section comprising electrically conductive portions 42 in which an electrically conductive particle 12 is incorporated in the form of a strip in the thickness direction of the adhesive and alternately arranged therewith a second section consisting of an adhesive only.

Title: Variable delay line circuit
Inventor: YAMAGUCHI YASUNOBU
IPC: H03H7/30
Filed: 1988-01-29
Abstract: PURPOSE:To decrease waveform distortion caused by the fluctuation of the capacity of a variable capacity diode by connecting one half of plural variable capacity diodes in a complementary direction, and controlling them with voltages having the same absolute value and reverse polarities in a variable delay line circuit having a voltage control means. CONSTITUTION:Since the reverse voltage impressed at the cathode edge of a variable capacity diode 4a is positive, the voltage impressed between the both edges of the variable capacity diode 4a is reduced at a part where at input signal is at a high level, and a delay quantity is increased because of the increase of the capacity. However, in a second stage, since the reverse voltage impressed at the anode edge of a variable capacity diode 4b is negative, it is reverse to that in a first stage. Consequently, in a second stage, the waveform is distorted in the reverse direction to the first stage. For this, the distortion of the signal waveform generated by the variable capacity diode 4a in the first stage is offset by the variable capacity diode 4b in the second stage. Since this is successively repeated, the waveform distortion due to the fluctuation of the reverse voltage can be decreased from the final output signal waveform.

IPC: G01D21/00
Filed: 1984-02-03
Abstract: PURPOSE:To reduce the consumption of a current by providing plural sensors which judges normalcy and abnormality from the flow of the current, a sensor loop current scanning circuit, and plural sensor loop current detecting circuits, and judging abnormality of plural loops by successive switching. CONSTITUTION:Output signal states on output signal lines 22a-22n of the sensor loop current scanning circuit 22 are varied according to a specific timing chart. Then only when logical levels on the output signal lines 22a-22n are 1, the 1st-the 4th sensor loop current detecting circuits 23-26 flow currents to corresponding loops. The currents flows to the respective sensors 31-34 successively for a specific time so that a current flow through only one selected sensor loop momentarily, and thus the currents flow while switched successively, so all the loops are monitored cyclically. Consequently, a long power failure guarantee time is secured even with a small-capacity battery.

Further, a solid solution having a composition consisting of 20-80wt.% Al2O3 and the balance Cr2O3 is thermally sprayed on the above layer to form an upper layer. When the ratio between components in the intermediate layer is beyond the above range, thermal shock resistance and insulating property become insufficient. Moreover, when the ratio between both components in the upper layer is beyond the above range, peeling and the adhesion of molten steel are brought about at the time of an immersion test into the molten steel.

Title: Changeover control system for master station/sub master station in cell multiplex packet loop
Inventor: KURANO TAKANORI
IPC: H04L12/40
Filed: 1989-01-26
Abstract: PURPOSE:To allow a sub master station to substitute a master station while discriminating it to be a faulty state of an opposite station with timeout by allowing a master station and the sub master station to send one packet to each other when a token passes through the stations and using a timer to monitor the reception of the packet. CONSTITUTION:In order to discriminate whether or not a master station 11 is normal, the master station 11 sends at least one packet to a sub master station 12 every time the token passes through the master station 11. Then the sub master station 12 uses a timer to monitor the packet 151 addressed to its own station from the master station 11 and discriminates it that the master station 11 is faulty at timeout. The sub master station 12 sends at least one packet to the master station 11 every time the token passes through its own station (sub master station transmission packets 161, 162). Then the master station 11 uses a timer to monitor the packets 161, 162 addressed to its own station from the sub master station 12 and discriminates the sub master station 12 to be faulty at timeout. The sub master station 12 acts like a master when the master station 11 is faulty.

Abstract: PURPOSE:To enable detection of an angle of crank rotation with a simple construction, by fixing a disc having marks at unequal intervals on a shaft to determine a cycle of mark passage from a sensor output while the passage of a specified mark is detected at a cycle ratio obtained. CONSTITUTION:A disc having marks at unequal intervals along the circumference thereof is fixed on a shaft rotating in synchronism with the rotation of an engine. A sensor for detecting the passage of the marks is set near the disc. The cycle of mark passage is determined by a cycle computing means from an output of the sensor. Then, a ratio between the cycle thus obtained and the preceding cycle is determined by a cycle ratio computing means. The resulting cycle ratio is compared with a reference value by a specified mark passage detection means to detect the passage of specified marks. Then, based on the frequency of passage of specified marks, a reference crank position is detected by a reference crank angle position detecting means. Then, based on the reference crank position and cycle thus obtained, an angle of rotation from the reference crank position is determined.
