Patent JP-H0651084-A (JP)
Title: Preventive maintenance method and device for welded part of through pipe
Inventor: ENOMOTO KUNIO
IPC: G21C13/00
Filed: 1992-03-31
Abstract: PURPOSE:To enhance the resistance against corrosive cracking due to stresses in a welded part by heating the areas in the neighborhood of the welded part to allow it to attain the high temp. generated in the stress exceeding the yield point, rapidly cooling the inner and outer surfaces with a reactor water, and converting the high tensile residual stresses into compressive stresses. CONSTITUTION:Areas around a welded part 3 including the heat affected zones 6c, 6s of a control rod guide pipe 4 and a stab tube 2 are high temp. heated locally from inside of the guide pipe 4. At the same time as attainment of the high temp., cooling waters 8a, 8s are spouted which use the reactor water from a cooling piece 7s on the outer side and a cooling coil of a heating/cooling piece 5 on the inner surface so that these surfaces are rapidly cooled simultaneously. Accordingly these areas undergo averaging due to redistribution of initial residual stresses and drop of the yield point of the material owing to the high temp. heating, and the residual stresses are dropped. At a stage on the way of this simultaneous rapid cooling of the inner and outer surfaces, compressive stresses are generated in the central part across the plate thickness while tensile stresses are generated at the inner and outer surfaces, and thus yielding is generated. Owing to this tensile yielding at the inner and outer surfaces, compressive stresses remain by contrast after complete cooling. That is, the tensile residual stresses are converted into compressive stresses, which enhances the resistance against corrosive cracking owing to stresses.

Title: Heat exchanger with immersed coil
Inventor: INOUCHI KEIJI
IPC: F28D1/06
Filed: 1978-06-22
Abstract: PURPOSE: To raise the heat exchange efficiency, by changing the radius of curvature of a coil so that some portions of the coil are located near an inner shell and the other portions adjacent to the formers are located near an outer shell.  
     CONSTITUTION: The vertical coil 1 is curved at different radii alternately so that its portions of major radius  of curvature are located near the outer shell and the portions of minor radius of curvature are located near the inner shell. As a result, a fluid rapidly flows on the outside surface of the coil without staying in the opening between the coil and the inner shell. Therefore, the effective heat transfer surface area of the coil is increased, namely, the heat exchange efficiency is raised.

Title: Analog and digital hybrid electronic timepiece
Inventor: AYUSAWA HITOMI
IPC: G04G5/00
Filed: 1981-05-21
Abstract: PURPOSE:To synchronzie an analog and a digital timepiece with each other by correcting the second digits of the digital timepiece part by the output of the correcting circuit of the analog timepiece part. CONSTITUTION:The output frequency of an oscillating circuit 1 is divided by a part 2 into a signal having a one-second period, and this signal is inputted to a second counter 3, a minute counter 4, and an hour counter 5 for measuring digital time. An electromechanical transducing driving circuit 6 for measuring and displaying analog time inputs the one-second period signal as well to drive an analog timepiece. Correcting signals for said counters 4 and 5 are generated by the operation of a switch 9 to correct the digital time. When a crown is pulled out, a switch 10 turns on to constrain the operation of the circuit 6 and at the same time the frequency dividing circuit 2 is reset. Simultaneously, the second counter 3 for measuring the digital time is reset.

IPC: G03F7/20
Filed: 1995-04-03
Abstract: PURPOSE: To make it possible to form large-area multidot diffraction grating patterns at a high speed and low cost while lessening manpower by imposing the same grating patterns on a base, forming mask patterns with another stage and controlling opening areas. CONSTITUTION: The diffraction grating elements 9 of dot units are exposed and imposed on a photosensitive base material 5 by irradiating an original plate 2 with illumination light 8 from a light source 7. This photosensitive material 5 is moved in X-, Y directions, by which the photosensitive base material 5 is made into an imposed blank 10 arranged with plural pieces of the diffraction grating elements 9 of the same shape in a matrix form. On the other hand, the blank 10 subjected to the imposition is placed on a scanning means and a mask plate is arranged in the position facing the blank and a lens 6 is interposed between both. The mask plate is irradiated with the illumination light 8 from the light source 7.  As a result, the mask patterns are transferred onto the surface of the base material and the opening areas of the diffraction grating elements 9 on the blank 10 subjected to the imposition are controlled to a desired size by the mask patterns of the mask plate.

Filed: 1989-03-29
Abstract: PURPOSE:To easily discriminate the present position by sending a control signal including a different zone data from a base station at a level receptible by a mobile station in each zone and allowing each mobile station to identify a received zone data. CONSTITUTION:A variable attenuator 15 of a base station 10 controls an output of a level transmission section 13 to a level received by mobile stations 20A-20C in plural zones through a control section 14 and the station 10 sends the output to a zone data specific to each zone. Reception sections 22A-22C of the mobile stations 20A-20C detect the zone data to inform it to annunciators 25A-25C through control sections 24A-24C. Discriminating zone belonging to its own station, the mobile stations 20A-20C communicate with the base station 10. Thus, the interruption of the communication due to a mobile station stepping out of the service area of the base station 10 is prevented.

Title: Interruption control method of electronic instrument with printer
Inventor: TSUJI SHIYUUJI
IPC: G06F3/12
Filed: 1983-05-02
Abstract: PURPOSE:To synchronize the print coil operation control processing of a CPU and the print operation of a printer by inputting a print synchronizing pulse generated at each print by the printer to the CPU as an interruption signal. CONSTITUTION:The CPU 2 receives a timing pulse from a programmable timer PTM 5 as an interruption signal at a non-print mode and executes a normal interruption processing such as display control thereby. Further, in a print mode, the CPU makes the timing pulse from the PTM5 ineffective, receives a print synchronizing from an I/O interface adaptor PIA6 as the interruption signal and executes the print coil operation control processing of the printer together with the normal interruption processing including the display control by means of the interruption processing.

Abstract: PURPOSE:To effectively eliminate drum assembly interchangeability noise by letting a signal pass a filter circuit having comb-line characteristic which is a ravine part corresponding to frequencies integer times of a changeover frequency for revolving head. CONSTITUTION:The output from a processing circuit 18 is supplied to an adder 19a through a connection switch 36. And a switching pulse SSW for head- changeover is supplied to a control signal generating circuit 37. The generating circuit 37 generates a signal SC which turns to high level '1' at a time in the vicinity of a head changeover time. When this signal becomes of high level, the switch 36 turns on and the filter circuit 17 shows the comb-line characteristic which is the ravine part corresponding to the frequencies integer times of the head-changeover frequency fs. On the contrary, because the signal SC is of low level '0', the switch 36 turns off and the circuit 17 shows a flat-line charac teristic.
