IPC: H02M1/00
Filed: 1991-05-16
Abstract: PURPOSE:To detect a failure in a semiconductor device automatically while the semiconductor devices are assembled in a converter by a method wherein gate signals are transmitted to the semiconductor devices and overcurrents of respective phases corresponding to the semiconductor devices are detected. CONSTITUTION:A device failure judging circuit 22 supplies gate pulses to semiconductor devices 5, 11, and 14 simultaneously through a gate pulse generating circuit 23. With this operation, a rated voltage is applied to semiconductor devices 9 and 10. If the semiconductor device 9 or 10 has a short-circuit failure, overcurrent detecting circuits 19 and 20 detect overcurrents. This procedure is successively repeated for the semiconductor devices 5-10 and the outputs of the overcurrent detecting circuits 19, 20 and 21 are checked to detect short- circuit failures in the semiconductor devices 5-10. With this constitution, the existence of short-circuit failures in the respective semiconductor devices can be judged while the semiconductor devices are assembled in a converter.

Title: Airborne speed measuring instrument for space navigation body
Inventor: KAWAHARA TETSUO
IPC: G01P3/36
Filed: 1989-04-28
Abstract: PURPOSE:To enable accurate navigation without any cumulative error by measuring the angle between the optical paths of two fixed stars by using a light direction measuring means and measuring the speed to an inertia system according to the optical path difference. CONSTITUTION:This instrument consists of a measurement part for the optical path angle between two fixed stars and a numeric calculation part. Then position data on images of the fixed stars 1, 2 on a photodetecting element 20 are obtained through the lens 10 of a photodetecting device. Then a digital computer finds the optical path angle from those position data and solves a specific equation to find the speed to the inertia system of the space navigation body. Consequently, the accurate navigation is possible without any cumulative error. Namely, speed vectors are found previously as to >=4 fixed stars and the angle between the light speed vectors of the two fixed stars observed on the navigation body is found; and the angles (optical path angle) of the respective light speed vectors are found as to four kinds of combinations and four simultaneous equations are solved to find an unknown vector V.

IPC: H03K5/00
Filed: 1989-04-28
Abstract: PURPOSE:To adjust the timing so as to surely receiver a serial data by comparing a latched data with an internally stored data equal to a serial data prepared in advance and controlling the delay time based on the result of comparison. CONSTITUTION:A host circuit sends the same data pattern as an 8-bit data stored in the internal register of a microcomputer 5 in advance as a serial data (a). The microcomputer 5 sets the delay time of the serial data by using a delay selection signal (d) to release a reset signal (f), a parallel data (k) is read by awaiting the time when a parallel data (j) is latched and the data is compared with an internal data pattern. The operation above is repeated for several number of times, and the delay time of a delay selection circuit 1 is fixed by using a delay selection signal (d) to the delay time in which the internal data pattern and the fetched parallel data pattern are completely coincident with each other. After the selection signal is fixed, a phase adjustment end signal (i) is sent to the host circuit to complete the phase adjustment of the serial data (a).

Abstract: PURPOSE:To reduce the arrangement work of symbols and connecting work with lines or the like by retrieving a graphic arranged near an arrangement point at the time of arranging a symbol on the graphic, and automatically connecting a line or the like extracted as an object to be connected with the symbol. CONSTITUTION:Linear graphic information is inputted from a linear graphic storing device 15 to a symbol arrangement processing part 112 and displayed on a graphic display 12. While observing the displayed linear graphic, an operator specifies a symbol name and its arrangement position. The processing part 112 reads out symbol defining information corresponding to the specified symbol name from a storage device 14 and arranges a symbol shape on the specified position on the linear graphic. The sort of a connection line is extracted from the symbol defining information and a line close to the arranged symbol is retrieved. When a new near-by line is detected, the sort is compared with the connection line sort of the defining information and whether the line is to be connected or not is decided. When the line is decided to be connected, the line is extended, cut off or moved so that the coordinates of the end point of the line coincide with a symbol connection reference point.

Abstract: PURPOSE:To enable simple automation of centering of panels of various shapes by moving upward the multiple needles of which the ends have been adjusted of height to the three-dimensional shapes of the panels having been press-formed and picking up the panels by the these ends. CONSTITUTION:When a panel 10 having undergone primary forming comes over a centering device, an elevator 5 works. Then, the ends of the forming needles 1 having beforehand been formed to a fixed shape ascend and the panel 10 is picked up by these ends, whereby it is accurately positioned. The panel 10 is then placed onto a press die by an automatic machine. The needles 1 are held slidably by a support 2 by means of leaf springs 4 and are fixed to spiral grooves 1a by being engaged with the projections 3a of clampers 3. At the time of die exchanging, the needles are unclamped and the bottom ends of the needles are brought into contact with the plates 9 by the descending action of the device 5 and are thereby made flat. A new sample panel is then pressed onto the needles to form the needles, after which they are fixed.

Title: Pump unit
Inventor: NAKAMURA KIYOUICHI
IPC: F04C2/344
Filed: 1981-07-20
Abstract: PURPOSE:To reduce pressure surge by coupling two pumps to a revolving shaft and by enabling discharged pressure medium from one pump to press a side plate in the other pump through a plunger, and vice versa, so that a gap between a side plate and a rotor may be automatically adjusted. CONSTITUTION:A fluid is sucked into two sets of suction ports 18 from a suction opening 26 due to the drive of a revolving shaft 2, and a pressure medium is discharged with pressure from a discharge port 19 due to the volumetric change of a pump chamber partitioned by a vane 10. Further, an excess amount of discharged flow which is increased, accompanied with an increase in the revolving speed of the shaft 2, is bypassed to a bypass passage 15 by a flow regulator valve 16, and is again sucked into the suction ports 18 through the suction opening 26. The operation of the first pump 3 causes the second pump 4 to be driven. The fluid pressure generated in the pump 4 is low when the number of revolutions of the pump 3 is slow, and therefore, the pressing force of a plunger 24 against the side plate 6 is small so that a gap between the side plate 6 and a rotor 9 becomes small. When the number of rotations of the pump 3 is high, the above-mentioned gap is largely changed due to the pressing force of the plunger 24.

Then, the output signal of the heat detecting element group 5 corresponding to the change is processed with the control and processing part 10, and converted to temperature in a temperature calculation part 11.
