Title: Method and apparatus for testing polarity of current transformer
Inventor: YONEDA MASATO
IPC: G01R31/06
Filed: 1994-10-20
Abstract: PURPOSE: To perform the polarity test of an air core current transformer easily and reliably even after the current transformer is assembled without modifying the structure thereof by providing a polarity test winding, a step voltage generating means and a pulse voltage detecting means. CONSTITUTION: With regard to a formula e2 =M12 (di1 /dt), where d/dt is a differential operator, an air core current transformer 11 has low mutual inductance M12 between a secondary winding 3 and a polarity test winding 6 but since the rising rate (di1 /dt) of a current i1 is high, the voltage e2 induced in the secondary winding has a detectable peak value. Furthermore, the voltage e2 induced in the secondary winding 3 is the derivative of the current i1 flowing through the winding 6, which means a pulse voltage having very short pulse width. The pulse voltage is detected by means of a pulse voltage detector 14 comprising an electronic circuit for detecting even a pulse voltage having very short pulse width thus testing the polarity of the current transformer 11 easily and reliably.

Abstract: PURPOSE:To prevent inaccurate conveyance of sheets to constantly maintain a fixed feed amount of the sheets by detecting an actual feed amount of the sheet by detection of the position of a stepping motor, stopping conveyance of the sheet when feed of the sheet is inaccurate, and continuing to convey after the inaccurate conveyance of the sheets is corrected. CONSTITUTION:A control unit 1 outputs signals for commanding the feed operation of sheets to be done to a stepping motor actuating circuit 2 and a comparison circuit 5. The circuit 2 then drives the stepping motor 3 by an angle corresponding to a feed amount of sheets by a signal inputted from the control unit 1. A position detecting circuit 4 then detects the position of the stepping motor and outputs a signal to the comparison circuit 5. The comparison circuit 5 compares the signal from the control unit 1 with the signal from the position detecting circuit 5, and outputs a stop signal 6 when both the signals do not correspond to each other. The circuit 2 received the signal 6 stops the motor, and the control unit 1 stops control until the position of the sheets is corrected and the sheets return to a normal position. When the position of the sheets is corrected and the sheets return to the normal position, output of the signal 6 is stopped, and the control unit 1 and the circuit 2 continue to operate again.

Abstract: PURPOSE:To provide a micro-crystal vibrator of a tuning fork type which has a zero temperature coefficient and the small equivalent series resistance and can easily undergo a chemical etching treatment by forming the grooves in the lengthwise direction to the tuning forks of the crystal vibrator which vibrates in a tortion vibration mode. CONSTITUTION:The grooves 4-7 are formed to the tuning forks 2 and 3 by an etching treatment, and the grooves are also formed on the opposite side at the symmetrical positions to the thickness in the same way. The exciting electrodes 9 and 8 are provided in the different polarities to the grooves 4 and 5 of the fork 2. These electrodes 8 and 9 are connected to the exciting electrodes of the grooves 6 and 7 via a tuning fork base part 10 in the different polarities to the thickness. In such a constitution, the voltage is applied between both electrode 8 and 9. Thus the electric fields are generated between the surface of the electrode 9 of the groove 4 at a position closer to the groove 5 and the surface of the electrode 8 of the groove at a position closer to the groove 4. As a result, the electromechanical conversion efficiency is improved. Thus it is possible to obtain a compact tortion crystal vibrator that has the small equivalent series resistance and the high Q value and furthermore can operate in a low frequency range of 200-600kHz.

Title: Microcomputer system
Inventor: NAKAMURA KAZUHIRO
IPC: G06F12/06
Filed: 1990-09-28
Abstract: PURPOSE:To prevent malfunction due to the error of memory access on an ISA(industry standard architecture) bus in DRAM unpackaging by providing a circuit which prohibits the output of an access strobe signal to a second slave device based on the discrimination result of an address space discrimination circuit. CONSTITUTION:It is distinguished whether a CPU 1 and a DMA address are within 16MB or are in a range behind that of 16MB by the address space discrimination circuit 23a, and it is controlled whether or not the access strobe signal(signals MEMR, MEMW) should be outputted to a bus of industry standard architecture(ISA) by a signal representing the discrimination result. Therefore, no memory access on the ISA bus is performed at an address within the range behind 16MB. Thereby, it is possible to eliminate the malfunction of the memory access in the DRAM unpackaging by outputting the signals MEMR, MEMW to the ISA bus only when the address is within the range up to address space 16MB.

IPC: F04C18/02
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a fixed scroll and/or a movable scroll with sufficient mechanical strength which corresponds to severe operation conditions and reduce their wear due to friction greatly by constituting the fixed scroll and/or the movable scroll by an alloy material which has a specific composition and is made of Si, Cu, Mg, and Al. SOLUTION: A fixed scroll and a movable scroll are constituted by an alloy material which is made of Si having 8 to 10weight%, Cu having 2 to 5weight%, Mg having 0.5 to 0.8weight%, and a remaining part Al. Si is an essential component for increasing mechanical strength, in particular, strength against high temperature fatigue. Since machining property and surface treatment property are reduced when many amount of Si is used, its upper limit is limited to 10%. Furthermore, Cu is an essential component for increasing machining property and the strength against high temperature fatigue at the same time. Moreover, Mg is added to increase mechanical strength. However, if many amount of Mg is used, extensibility disappears and machining property is reduced. Therefore, its upper limit is limited to 0.8%.
