Title: Method and apparatus for driving motor
Inventor: IKEDA HIROYUKI
IPC: H02P6/06
Filed: 1993-03-29
Abstract: PURPOSE:To make it possible to prevent the short circuit of a PWM inverter by reading the correcting value of a conducting timing conforming to the current detected with a current sensor, and correcting a rotor angle. CONSTITUTION:In a switching control device 3, a driving command value at this time and a driving command value at the previous time with respect to upper and lower switches Q1 and Q2 are multiplied. When the polarity of the result of the multiplication is negative, the output of the driving command value at this time is made zero. The device 3 has this function. When the driving command value at this time and the driving command value at the previous time are multiplied in the state, wherein the driving command value is imparted into the upper switch Q1, the polarity becomes positive. When the driving command waveform of the sine wave is changed from the positive value to the negative value during the switching period from the upper switch Q1 to the lower switch Q2, the polarity of the multiplied value of the driving command value at this time and the driving command value at the previous time becomes negative. At this time, in the switching control device 3, it is judged that there is the possibility of the simultaneous turning-ON of the upper and lower switches Q1 and Q2. The output of the driving command to the lower switch Q2 is made zero. As a result, the short circuit of a DC power supply can be readily prevented.

Title: Synchronization clock distribution system for synchronization transmission system
Inventor: TAKAMI MASAYUKI
IPC: H04L7/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To warrant phase synchronization among plural synchronization transmitters even on the occurrence of a fault in any of synchronization clock distribution lines with redundant configuration. SOLUTION: Ring distribution lines R0, R1 for 0 system/1 system synchronizing clocks CK0, CK1 are formed by interconnecting a distributed clock system(DCS) 1 and synchronization transmitters 21-2n by distribution lines L00-L0n and L10-L1n respectively as rings. Each of the synchronization transmitters 21-2n relays respectively the 0 system/1 system synchronizing clocks CK0, CK1 but stops a synchronizing clock to be outputted to a succeeding transmitter upon the detection of a fault in the synchronizing clock being received. Thus, on the occurrence of a fault anywhere in the distribution lines L00-L0n and L10-L1n, the synchronizing clock to be returned to the DCS 1 is missing. The DCS 1 receives/monitors the synchronizing clocks CK0, CK1 outputted by itself and in the case of detecting clock missing, the DCS 1 stops output of the missing synchronizing clock.

Abstract: PURPOSE:To improve the translation capability of a machine translation system by additionally registering an example of original-translation in an original-translation data base. CONSTITUTION:First and second language character strings are preliminarily generated as a translation example (original-translation). The first language character string is inputted to a first language character string input means 3, and the second language character string obtained by translating the first language character string to the second language is inputted to a second language character string input means 4. Inputted first and second language character strings are displayed on a display means 5. A correspondence means 6 makes first and second language character strings displayed on the display means 5 correspond to each other. A register means 7 registers first and second language character strings, which are made correspond to each other, in an original-translation data base 1. At the time of translation, a translating means 2 retrieves the first language character string, which is a similar or exact equivalent expression for an original character string, from the original-translation data base and translates the original character string to the second language based on the second language character string corresponding to the retrieved first language character string.

Abstract: PURPOSE:To dissolve the unevenness of temperature in the width direction of a strip and to uniformize the distribution of temperature in the width direction. CONSTITUTION:In a method for cooling a hot line of a hot-rolled strip 2, distribution of the temperature in the width direction is measured continuously by width direction temperature detectors 4, 5 installed on the outlet side of a finish rolling mill 1 on a hot rolling line and on the inlet side of a coiler 3 respectively and plural side spray nozzles 12 which face each other on both sides in the width direction of the strip 2 and can freely control spraying angle, spraying rate of water are arranged independently of a group of hot run spray headers 8. The rate of cooling water necessary to make the difference between the maximum and minimum temperatures null and the spraying angle of the side spray nozzle 12 to spray the cooling water to a position at the maximum temperature in the width direction is calculated based on the measured result of the temperature distribution in the width direction of the strip 2 to control the spraying angle and spraying rate of water of the side spray nozzle 12 based on the arithmetic result. Consequently, unevenness of the quality caused by the temperature difference between both edge parts and the central part can be prevented.

Title: Redialing system
Inventor: HANAWA KAZUHIKO
IPC: H04Q3/58
Filed: 1981-05-13
Abstract: PURPOSE:To prevent an erroneous connection, by providing a memory for storing the number of digits, dialing number and dialing inter-digit timing, by which outgoing dialing has been executed, and sending out dialing by the inter-digit timing in this memory. CONSTITUTION:When a terminal TO calls continuously, a calling signal is sent out to a central controller CC. The CC detects this call and stores the number of dialing digits, dialing number and dialing inter-digit timing for executing redialing a data related to dialing to a stored memory. Subsequently, when the TO calls and executes a redialing request, dialing is read out from the stored memory, and the operation is executed as if the dialing has been received from the TO. In this way, since the operation is executed by dialing timing dialed by a calling party previously. the erroneous connection is reduced. In this case, the dialing sending-out timing can be shortened by storing in advance the number of digits in an automatic pause designating memory and automatically changing the dialing inter-digit timing to the minimum inter-digit timing.

Filed: 1978-06-13
Abstract: PURPOSE:To prevent the evolution of gas in secondary battery and prevent the danger of explosion by appropriating the output of solar batteries to driving of circuits and charging of the secondary voltage when it is above a certain level and appropriating the same only to charging of the secondary battery when it is below said level. CONSTITUTION:Beforehand, the maximum value of photoelectric current of the extent of not evolving gas that can be supplied to a secondary batter 5 is set. On the primary battery 1 side, the output current thereof is converted to voltage through a stable resistance which is difficult to receive the effect of the outside and the output voltage thereof is administered in a battery voltage detector 2. If the output current is larger than the foregoining charging current, said output is sent to the load 4 side by a changeover device 3 and is at the same time supplied to the secondary battery 5 side. Next, if the output current is smaller than the foregoing charging current, it is directly charged to the battery 5 side by the device 3 and the output of the battery 5 is appropriated to the load 4 side. As a result, the evolution of gas in the secondary battery may be prevented and the danger of explosion prevented.
