Title: Output current detector of pwm inverter
Inventor: MURAI YOSHIHIRO
IPC: H02M7/48
Filed: 1994-06-30
Abstract: PURPOSE:To detect three-phase AC currents by detecting a current on a DC side with one current sensor. CONSTITUTION:A current on the DC side of the main circuit 11 of a PWM inverter is detected by a current sensor 12. The currents of the respective phase arms of the main circuit are successively sampled by sample holding circuits 13 and 14 immediately before and after the switching in accordance with a PWM waveform and stored. Subtraction between both sampled values are successively performed by a subtractor 16 to obtain the changed component of the DC current before and after switching. The changed component is varied while including information of the output currents of respective phases and are distributed to the respective phases by a distribution operator 17 to obtain the detected currents of the respective phases. A timing controller 15 obtains sampling timing signals and timing signals for the distribution to the respective phases from the PWM waveform.

Title: Spotting method for accident point of cable
Inventor: YAMAGATA TOKUZOU
IPC: G01R31/08
Filed: 1980-10-27
Abstract: PURPOSE:To stop an accident point accurately without reference to the state of the ground surface by connecting a DC power source between a cable and the mimic line of an open wire laid on the ground surface along the laying path of the cable. CONSTITUTION:The negative terminal of a DC power source flowing a direct current through a cable 1 is not grounded, but connected to the mimic earth line 5 of an open wire laid on the ground surface GL along the laying path of the cable 1. Then, a return-circuit current from an accident point 4 flows to the mimic earth line 5. For the purpose, the earth line 5 is disconnected and an ammeter 3 having a small resistance R detects the direction of the current. Since the direction of the current depends upon the position of the accident point 4 and the relative position of a detection point 5a, the disconnection of the earth line 5, measurement, recovery at the disconnection point, disconnection another point, measurement, etc., are performed repeatedly to spot the accident point as well as the conventional potential difference method. Thus, the accident point is spotted accurately without reference to the state of the ground surface.

Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide an electron beam lithography apparatus which is inexpensive and can perform a high-grade external magnetic field shielding. SOLUTION: Generally, a magnetic circuit part between magnetic field type electron lenses among magnetic circuit parts 7 of a focusing electron lens system is a part where transmitted magnetic fluxes are fewer. Hence, this portion is provided with a magnetic flux shunting nonmagnetic part 8, for example, composed of a cavity which opens to a magnetizing coil of a lower electron lens, and accordingly, a magnetic circuit part existing between electron lenses is formed as a shunting magnetic circuit part regarding the lower electron lens. With this configuration, regarding the lower electron lens, magnetic fluxes generated at the magnetizing coil are shunted so as to pass through a magnetic circuit part surrounding the magnetic flux shunting nonmagnetic part 8, that is a shunt magnetic circuit part, and therefore the magnetic flux density in the shunt magnetic circuit part increases compared with a case without the magnetic flux shunting nonmagnetic part 8, i.e., the magnetic permeability at the part is increased.

Title: Detecting device for card packing state
Inventor: TORIYAMA KAZUHIKO
IPC: G06F11/30
Filed: 1986-06-26
Abstract: PURPOSE:To detect the difference between the packing data put into a program and the card packing state by transmitting a signal onto an individual bus which selects the individual cards to detect the presence or absence of a card packed. CONSTITUTION:The address signal 5 outputted from a CPU to specify a card 1 is decoded by an address decoding circuit 4 to be turned into a card selector signal 6. This signal 6 is sent to the card 1 via an individual bus (b). When the card packing state is detected, a check signal 3 is set at an H level. Thus the signal set on the individual bus changes as follows. That is, the bus (b) is not affected easily by the circuit 4 in a card packing mode. Thus the signal on the bus is sent back to the bus (b) at an L level. In this example, the effect of the signal 3 is also eliminated and therefore the signal on the bus is kept at an H level by a pull-up resistance 8.

Abstract: PROBLEM TO BE SOLVED: To make it possible to generate a retrieval result set equivalent to a retrieval result set generated on the basis of a current table by issuing a request to generate the retrieval result set to obtain the latest information when the table is possibly updated after the retrieval result set is generated. SOLUTION: When the retrieval result set is included in the update line ID of a table update log 39, the update line ID is deleted from the retrieval result set unless an after-update image of the table update log 39 meets the retrieval conditions of retrieval result set management information 35.
