Title: Fillet welding method
Inventor: KOYAMA KOUICHI
IPC: B23K9/02
Filed: 1977-10-19
Abstract: PURPOSE: To enable the accurate inspection for internal defects, by welding so that the section of weld zone may form a rectangle or a square.  
     CONSTITUTION: In the case where the end face of the material 2 is jointed to the material 1 by the fillet welding, the welding is performed so that the section of the weld zone 4 may form a rectangle or a square. With this method, it becomes possible to carry out the inspecting method with the radiation transmission or the inspecting method with the ultrasonic flaw detection by using the faces 5 and 6 of the weld zone 4 as the inspection face and, further, because the virtual image or pseudo- echodoes not occur, the internal defects can be inspected easily and accurately, and  the quality of the fillet weld zone can be improved sharply

Title: Picture processing system
Inventor: MASUDA YUKIO
IPC: H04N1/40
Filed: 1984-06-19
Abstract: PURPOSE:To obtain pictures of high quality and reduce influences of erroneous discrimination by making a sharp distinction between character areas and half- tone areas with respect to picture blocks and applying OR data between binarized picture data and picture data subjected to dither processing to blocks of character areas. CONSTITUTION:Picture information in a block memory 11 is binarized with a certain threshold of a fixed threshold memory 12 by a fixed threshold binarizing circuit 13 and is stored in a binary picture memory 16, and meanwhile, picture information in the block memory 11 is subjected to dither processing by an organic dither processing circuit 15 and is stored in a binary picture memory 17. A picture quality discriminating circuit 20 refers to picture information in the memory 11 to discriminate a noticed block as a half-tone area or a character area and transmits the discrimination signal to a selecting circuit 19. If the discrimination signal indicates a half-tone area, the circuit 19 outputs the binary picture in the memory 17; but if this signal indicates a character area, the circuit 19 obtains the signal of OR between binary pictures stored in memories 16 and 17 by an OR circuit 18 and uses this signal as the output signal.

Abstract: PURPOSE:To re-edit an input signal and to display an individual signal which is easy to discriminate on the screen of an oscilloscope tube by providing a means which detects the generation period of a 2nd signal from an instrument to be measured. CONSTITUTION:A trigger circuit 40 detects a pulse from the input signal 15 automatically and outputs its detection signal to the external input terminal of an oscilloscope 10 through a data processor 60 and a gate 59. A trigger circuit 50, on the other hand, outputs a signal from a trigger probe 21 which is provided newly to the data processor 60. The data processing circuit 60 processes input data from the trigger circuits 40 and 50 and outputs their results to an adding circuit 30. The adding circuit 30 adds the signal 15 from the instrument to be measured and the output of the data processing circuit 60 and sends the sum to the signal input terminal of the oscilloscope 10. Consequently, the oscilloscope operation assisting device is obtained which can displays the easy-to- discriminate individual signal on the tube screen of the oscilloscope 10.

Title: Modulation type dc amplifier
Inventor: NAKAZOE ATSUSHI
IPC: H03F3/38
Filed: 1983-07-09
Abstract: PURPOSE:To reduce the voltage drift due to the spike voltage by giving the inversion of polarity to one of two wave detection outputs for every half cycle of the chopper switching cycle and then adding both wave detection outputs together. CONSTITUTION:A compensating impedance Zc which is equal to the impedance of a signal source is set in series to a parallel switch Q2 of a chopper circuit 2. Then a detecting circuit detects the output signal given from an AC amplifier A2 for every half cycle of the chopper switching cycle. The inversion of polarity is given to one of two detection outputs of each half cycle, and both detection outputs are added together. Therefore the spike voltage generated from a chopper circuit has the same waveform for every half cycle and then divided for every half cycle by the detecting circuit to be added together with opposite polarities. Thus these spike voltages are eliminated to each other. Thus, the voltage drift due to the spike voltage is reduced remarkably.

Subsequently, by a bus access type signal 12 received together with the CPU address 2, the number of pre-fetch blocks is varied. In such a way, by setting the corresponding optimal pre-fetch blocks at every bus access type, a high hit rate can be obtained.

Abstract: PURPOSE:To increase the processing speed for registration by keeping each queue control means wait for read processing request until a processing request is registered by the queue control means for said request. CONSTITUTION:Each processor of a multi-processor system has a queue control part 21. A processor confirms that a processing request information is given to itself from a processing requester 1 via a data bus 3-1 and then controls a registration processing circuit 213 to select a registration pointer register 214 via a pointer switch 217. Then the processing request information is written to a processing request stack memory 211 for registration. Then the contents of the register 214 are renewed and the end of registration is transmitted to a processor part 22. The parts 22 accepts the end of registration and informs this to a control part through a line 2200. However this information is not sent to the control part if a registration processing request is detected on a data bus 3-1 and the read processing is not carried out.

Filed: 1994-05-16
Abstract: PURPOSE:To record signals by means of composite shot while keeping the continuity with simple configuration by storing 1st and 2nd field identification numbers A, B recorded at last and revising numbers when numbers A, B to be recorded next are not coincident with the stored number. CONSTITUTION:First and second field numbers (VID and AUID) of a video signal S1 and an audio signal S10 recorded finally are stored in a prescribed memory. When the VID in the VID and AUID to be recorded next is coincident with the VID stored in the prescribed memory, the recording is started from a succeeding field. Thus, when the VID is not coincident and the AUID is not coincident with that stored in the memory, a recording control section 10 allows an ID offset circuit 7 to revise the AUID. Thus, the VID and AUID are consecutive at composite shots and the composite shot recording is conducted while keeping the continuity of the recording sequence of the signals S1, S10 with simple configuration.
