Title: End cock welding method for covering tube of atomic fuel
Inventor: NAKATSUKA MASAFUMI
IPC: B23K9/00
Filed: 1979-09-19
Abstract: PURPOSE: To prevent the mixing of the components of the barrier layer into the welded metal part and thus increase both the strength and the anticorrosive property, by performing the welding after eliminating the barrier layer of the covering tube of the atomic fuel.  
     CONSTITUTION: The nuclear fuel pellet is stored within the covering tube made of the zirconium alloy, and then the end cock is welded to both end openings of the covering tube. In such case, the barrier layer formed on the surface of the covering tube is removed mechanically via the carborundum paper or the like or by washing with an acid. After this, the covering tube is washed sufficiently in the fresh water and then dried. And then the end cock is put to the tube through the TIG welding. In this method, the intensity at the welded metal zone can be increased up to a level nearly equal to that of the covering tube with no barrier.

Filed: 1990-05-09
Abstract: PURPOSE:To shorten the connection time with a host computer and to prevent mis-dialing of a telephone number by bringing a host device and the portable terminal into the on-line state in response to bar code information of a bar code part read by a bar code reader. CONSTITUTION:Bar code information resulting from bar-coding a telephone number of a host device is displayed on a bar code section 2, bar code information read by a bar code reader 3 from the bar code section 2 is converted into a dial pulse and the result is sent to a telephone set to bring the state with the host device into the on-line state. Thus, the portable terminal and the host device are brought into the on-line state without dialing of the telephone number of the host computer by the operator. Thus, the connection time with the host computer is shortened and mis-dialing of the telephone number is prevented.

Title: Repeater monitor system
Inventor: TOGOSHI TOSHIROU
IPC: H04B17/40
Filed: 1977-10-04
Abstract: PURPOSE:To ensure a quick and accurate detection for the faulty repeater even in  case the repeating transmission is in overload, by memorizing the information when  the level variation of the fault search monitor signal is received. CONSTITUTION:Repeaters 5-8 which receive AGC via the pilot signal transmitted from transmission end office 1 are connected vertically, and the fault search monitor signal is inserted to the input of each repeater. Now if repeater 5 had some fault, receiving end office 9 receives accurately fault search monitor signal 2 for a few seconds before the repeater becomes overload, and the signal 2 is memorized in repeater monitor circuits 13-15. Thus, no effect is given to the information of the repeater fault which was detected before even though the repeating trasmission line becomes overload and relay 18 has malfunction. As a result, a quick and accurate detection is possible for the faulty repeater even in case the repeating transmission line is in overload.

Filed: 1983-06-29
Abstract: PURPOSE:To suppress the variation in a DC bus voltage to the minimum limit when an operating mode is shifted by generating an operating mode conversion acceleration signal when the operating mode is shifted, and shifting the operating mode of a converter. CONSTITUTION:When the part of induction motors which are operated at the aligned speed are shifted to a regenerator operation, a DC bus voltage Vd starts rising, a power drive generative conversion detector 11 outputs to close a switch 12. Accordingly, an operating mode conversion acceleration signal P is applied in the same polarity as the output of a DC voltage detector 7 to a butting point. Since the signal P has considerably large level, the input of a voltage controller 9 becomes a large regeneration command input, a converter 2 is shifted rapidly to the regenerative operation, and the rise of the voltage Vdc is accordingly suppressed, and the variation in the speeds of induction motor IM group which are not operated at the aligned speed.

Title: Electronic controller
Inventor: KUROKAWA KAZUNORI
IPC: H02P8/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To prevent wrong control of an object of control at the occurrence of a communication error in an electronic controller, where a control circuit serially transmits control data to a drive circuit and the drive circuit converts the control data into parallel data so as to generate a drive signal for the control object. SOLUTION: In this electronic controller, a CPU serially transmits control data for driving a step motor to a drive circuit (120, 130), and a drive circuit converts the control data into parallel data and provides an output of a drive signal. The drive circuit is configured so as to echo back the received control data, the CPU discriminates the normality/abnormality of communication, depending on whether the echo-backed data are coincident with the transmitted control data (output data) (150) and transmits the control data again at the occurrence of a communication error. Furthermore, until the normality of communication is confirmed, a signal CS is set to a low level (110), to inhibit the drive circuit from outputting a drive signal corresponding to the received data.  When the normality of communication is confirmed, the signal CS is set to a high level (160) to permit an output of the drive signal from the drive circuit.

IPC: H02M7/537
Filed: 1992-05-13
Abstract: PURPOSE:To prevent distortion of the output voltage of a PWM inverter due to short circuit preventing time even near a voltage saturation region, in the PWM inverter used for variable-speed drive of an AC motor. CONSTITUTION:In each phase of a PWM inverter 3, by an output voltage compensating circuit 10, the signal sensed a current polarity sensor 8, which depends on the polarity of the output current of the inverter, is added to the output voltage command issued from an output voltage command circuit 4 of the inverter. When the result thereof exceeds the amplitude of a carrier wave, which is sensed by a carrier wave amplitude sensor 9, the difference between the amplitude of the carrier wave and the original output voltage command is accumulated. Then, the signal corresponding thereto is added to the output voltage command, and the result thereof is outputted to a comparator 7. Thereby, the actual output voltage of the inverter coincides on an average with the original output voltage command, and distortion of the output voltage of the inverter can be compensated even near a voltage saturation region of the inverter.
