Abstract: PURPOSE:To enable the test of a logic circuit wherein a test standard is specified by a relative voltage value between two signals by converting the relative voltage of the two signals to a voltage waveform that changes up and down while centering a reference point and comparing the voltage waveform with a comparison voltage. CONSTITUTION:An instrument wherein input signals are compared with a comparison voltage value in analog comparing circuits 6 and 7 to be converted to binary signals and the binary signals are compared with reference data in a digital comparing circuit 8 whereby a logic circuit is tested, is provided with a converting circuit 5 for converting a relative voltage value between two inputted signals to a voltage waveform that changes up and down while centering a reference point. The circuit 5 leads the relative voltage value between the two signals inputted through terminals A and B to the voltage waveform that changes up and down while centering the reference point and supplies the voltage waveform to the circuits 6 and 7. The circuits 6 and 7 obtain the binary signals from the voltage waveform and feed the binary signals to the circuit 8, which compares the binary signals with reference data supplied from a computer. Thus, the logic circuit defined by the relative voltage value between the two signals can be tested.

Title: Production of stainless steel-made thin parts
Inventor: UEHARA HIDEHIKO
IPC: B63H1/14
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To improve the productivity by reducing processes and manhours, to lighten a product by thinning, to improve a cast surface and to prevent the development of cast defect. SOLUTION: A stainless steel-made thin parts 4 containing a prescribed quantity of Si and having 1400-1700 deg.C melting temp. is formed with a shell casting method. Since the shell casting method having remarkably less process than a conventional lost wax method is used, the processes and man-hours are remarkably reduced, and the productivity is improved. Further, the generation of gas is reduced because the melting temp. of the stainless steel material is lower than that of the conventional material, and further, since the generated gas is exhausted by passing through the shell mold 1, the cast defect of blow hole, etc., in the product 4 is not developed, and the machinability of the product 4 is improved.  Then, the roughening of the cast surface due to the sand of the shell mold 1 melting onto the surface of the product 4 is not developed, because the temp. of the molten metal 2 is low, and the extremely good cast surface is obtd.

Abstract: PURPOSE:To prevent the hunting by detecting the hunting of reactive power compensating device (SVC) and switching the output reactive power of an SVC from the feedback control to the control to fix the output value of the SVC or the control from other control circuit. CONSTITUTION:When an output Q of a PI circuit 12 becomes Qmax or above, a switching device 13 communicates the output Q of the PI circuit 12 to a PHS 13 and an SVC is feed-back-controlled. Next, when the output Q becomes Qmin or below shown by a setting device 17-2, the output of a comparator 18-2 is changed from 0 to 1 and the output of an FF19 is changed from 1 to 0. The output of a counter 20 and a pulse generator 25-1 is not changed even when the FF 19 is changed from 1 to 0. On the other hand, since the output of the pulse generator is 1, the output of an AND circuit 23-2 is changed from 0 to 1. The output of a hunting detecting circuit 14 is changed from 0 to 1 and it is decided to be the hunting. Therefore, a switching device 16 is switched, the selection is changed from the output Q of the circuit 12 to a set value Qman shown by a manual control setting device 15 and communicated to the circuit 13. The control of the SVC is changed to a fixed value control.
