Title: Data processor
Inventor: MATSUMOTO HIDEKAZU
IPC: G06F9/38
Filed: 1982-09-03
Abstract: PURPOSE:To execute instructions accessed before an exception occurs from a main memory during memory access and to reduce an overhead, by storing whether an exception in an instruction prefetched from the main memory is present or not. CONSTITUTION:An instruction and an operand stored in a main storage device MM are pre-fetched by an instruction fetch unit IFU through a main storage controller MCU and a high-speed buffer memory BM1. The IFU stores the pre- fetched instruction and information on whether an exception occurs or not and outputs them to a decoder DU, which performs exceptional processing once detecting the presence of the exception. An address is calculated AU from the output of the decoder DU to fetch OFU the execution address of the operand. The OFU sends the address to a high-speed buffer memory BM2 to fetch the operand in advance. An execution unit EU receives and executes the instruction from the OFU. The BM2 passes data in an address read out by accessing the MM to the OFU when no data is passed through the OFU.

Title: Iron core for three-phase transformer
Inventor: YAMAGUCHI SHIYOUYUU
IPC: H01F27/245
Filed: 1982-09-03
Abstract: PURPOSE:To improve the work efficiency in the upper yoke iron plate inserting operation while maintaining the rigidity of core joints, and to permit the reduction of an iron loss without using a nonmagnetic body for a core cover plate, by disposing the core cover plate in such a way that it will overlap only with the lower yoke of the core and by separating the upper end from core tightening metal fittings, thereby providing magnetic insulation thereto. CONSTITUTION:An iron core cover plate 3, together with core tightening metal fittings, are made of structual steel of ferromagnetic material. The lower end of the cover plate 3 is extended from the end surface of the core and overlapped on a lower yoke 12. The upper end of the cover plate 3 is brought up to the vicinity of the end surface of the core, and is so devised that it will not overlap with an upper yoke 11. In addition, the cover plate 3 and the upper core tightening metal fitting 5 are magnetically insulated by separating the upper end of the cover plate 3 from the upper core tightening metal fitting 5. As a result, when performing an iron plate insertion operation for the upper yoke 11 after inserting a coil 2 into an iron core, it is possible to easily locate iron plate inserting hole and the work efficiency can be improved. Furthermore, since the upper core tightening metal fitting 5 is magnetically insulated from the core cover plate 3, a magnetic circuit is not formed, with the result that an iron loss can be reduced without using a ferromagnetic material for the core cover plate 3.

IPC: G01R31/00
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To accurately measure a threshold value even when a signal level converting circuit is arranged in the front stage of a comparator by performing Fourier transform on the output signal by inputting a sine wave signal to the comparator. SOLUTION: When a sine wave generator 10 is driven in a state of not setting a threshold value in a comparator 5, a generated sine wave signal is inputted to the comparator 5, so that Fourier transform is performed on the output signal by a Fourier transformer 20. The processing part 35 of a threshold value detector 30 stores this Fourier transform result in the storage part 31 as a common phase term. Next, the sine wave signal is inputted to the comparator 5 in a state of setting plural threshold values to determine the phase term of the Fourier transform result of the output signal to the respective threshold values with every threshold value.  A phase by subtracting the phase term and the common phase term is also determined with every threshold value so that amplitude of the sine wave signal corresponding to these determined respective phases is outputted from the output part 40 as a threshold value set in the comparator 5.

Abstract: PURPOSE:To eliminate the necessity of a charging resistance from a capacitor type power supply device for welding so as to miniaturize the device by directly connecting capacitors to the output terminal of a rectifier circuit and, at the same time, providing a charging control circuit which charges the capacitors by supplying constant currents during most of a charging period. CONSTITUTION:When capacitors 112 and 114 are directly connected with the output terminal of a rectifier circuit 108 and no charging resistance is provided between the capacitors 112 and 114 and, at the same time, charging currents which are controlled to constant currents are supplied to the capacitors 112 and 114 under the control of a charging control circuit 10, no charging resistance is required for suppressing the flow of an excessive charging current at a charge circuit. Therefore, the problem of heat production by the charging resistance is solved, useless power consumption is eliminated, and installation of a cooling mechanism for heat radiation becomes unnecessary. In addition, replacement and switching of the charging resistance also become unnecessary. Moreover, the capacity and size of a transformer 104 can be reduced, since no voltage drop is produced by the charging resistance.
