Title: Electric discharge machine
Inventor: FUTAMURA SHIYOUJI
IPC: B23H7/02
Filed: 1984-06-22
Abstract: PURPOSE:To work a slit having a uniform slit width and a slit depth at the desired positions by using a band electrode and installing an auxiliary guide nipping the band electrode in slidable ways and regulating the traveling position of the band electrode. CONSTITUTION:When a parallel and rectilinear slit 2 is worked onto the side surface of a workpiece 1, a band electrode 3 in width (w) X thickness (t) is traveled in the direction of arrow (z) by a taking-up roller 6, guided by main guide rollers 4 and 4'. The band electrode 3 is applied with a tension in the direction of arrow (z) by a brake roller 7. It is necessary to increase this tension as large as possible. When the allowable max. tension for the band electrode 3 is compared with that in case of a wire electrode, the larger tension can be applied in comparison with that in case of the wire electrode. Further, the generation of the transverse swing phenomenon with respect to the direction of traveling of the band electrode 3 between the main guides 4 and 4' can be exceedingly reduced by installing an auxiliary guide 5 in comparison with the case of the wire electrode.

Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of cracks of a stock during the pressing by pressing a designed part to be pressed which is locally set on the stock to perform the work hardening of the designed part so that a plurality of dimples are formed through the plastic deformation on its surface before the stock is pressed. SOLUTION: A steel plate to be pressed is first shear-cut to have appropriate size to obtain a stock 10. The dimple pressing is applied to a designed part 22 to be pressed of the cut stock 10. A plurality of dimples as a plurality of dent parts are formed by the plastic deformation on a surface of the designed part 22 to be pressed. The designed part 22 to be pressed is set to a part 24 for possible breakage easy to generate cracks in the stock 10 during the pressing. The designed part 22 to be pressed is subjected to the dimple pressing to form a dimple pressed part 26 with work hardening. The pressing is performed by a pressing die after the dimple pressing.

Title: Spreader position controlling method for transfer crane and controller thereof
Inventor: SHIMAMURA SHINTARO
IPC: B66C19/00
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To surely load a container efficiently without causing any collision of a spreader or the container hung by the spreader with stacked containers. SOLUTION: By means of a distance measurement sensor 20, the height of each side of the level of stacked containers 11, and the number of stacked layers of containers 8 is determined. If the height of the both sides on this layer are equal to each other, position control is carried out so that a spreader 7 is moved to the loading position from the next higher layer or to the unloading position from the next lower layer. In this way, in loading/unloading of the container 8, the container 8 can be automatically lifted/lowered through the shortest distance while being prevented from a collision against the stacked containers 11 without depending on the decision of an operator.

Title: Thermal transfer type printer head
Inventor: MORIKAWA SAICHI
IPC: B41J2/335
Filed: 1989-05-22
Abstract: PURPOSE:To enable control of electric current of a heating element to be simplified and to enable contact pressure to be increased by a method wherein heating elements arranged in an anay on a base layer and a protective film layer covering the heating element are established, and a groove is formed to the protective film layer between respective adjacent thermal resistors. CONSTITUTION:A printer head 1 is composed of a heating element anay 2 formed on a base layer and electrodes 3 connected to this heating element anay 2. By making electric current flow to a heating element 6 enclosed by a protective film layer 5 on the base layer 4, heat is generated, and ink of an ink film is transferred to paper by melting the ink of the ink film by said heat. A groove 7 is formed to the protective film layer 5 between the heating elements 6. Therefore, for heat to be generated to the heating element 6, since thermal conductivity of air being the groove 4 is low by comparing with glass or the like composing the protective film layer 5, mutual influence of heat of the heating elements 6 becomes small. That is, necessity for control of electric current according to whether electric current is made to flow to adjacent heating elements 6 or not, disappears. Supposing force pressing the whole of the head is the same, since an area coming in contact with a ribbon is decreased by comparing with a no groove 7 state, pressure per unit area between the ribbon and the head is increased.

Title: Firing preventer for ash deposited in boiler
Inventor: TOMII TAKASHI
IPC: F22B37/54
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To lower the temperature of a boiler quickly after extinguishment by disposing a temperature detecting means and a nozzle means for ejecting cooling fluid in a layer of ash deposited at a part in a boiler where the ash is deposited easily thereby preventing the ash deposited on the bottom part in the sub-chamber of the boiler from firing. SOLUTION: Ash ascending from the combustion chamber 1 of a boiler flows, by a small quantity at a time, into the sub-chamber 2 of the boiler through a gap 9 at the water-cooled wall penetrating part of the heat transfer tube 4 of a superheater and ash deposits 3 on the bottom. Since boiler water for adjusting temperature does not circulate through the heat transfer tube 4 and the header 5 of a superheater after the boiler is extinguished, temperature in the sub-chamber immediately after extinguishments of the boiler is about 450-550 deg.C which is substantially equal to the steam temperature. Temperature measuring nozzles 12 and cooling spray nozzles 10 are provided side by side in the sub-chamber 2 of the boiler and when the internal temperature of ash deposited 3 on the bottom exceeds 200 deg.C, inactive gas, e.g. nitrogen gas, or extinguishing water is sprayed from the cooling spray nozzles 10.

Abstract: PURPOSE:To obtain an image pickup picture without misregistration by emitting a stroboscope with a detecting signal obtained by a sensor, identifying whether the odd number or even number field of the image pickup signal is obtained with a light emitting timing and fetching the image pickup signal. CONSTITUTION:Since a subject 11 enters an image pickup visual field, a detecting signal obtained from a sensor 12 gives immediately the light emitting command to a stroboscope illumination light emitting means 14, light-emits the stroboscope and with light emitting timing of the stroboscope, it is identified whether the image pickup signal sent from a television camera 13 is an odd number or an even number and in accordance with the identification result, the image pickup signal is fetched. As this result, even when the stroboscope light emitting timing identifies any of the odd number or the even number, the image pickup signal can be fetched by synchronizing to the field immediately after the light emitting timing, and the correct image pickup picture with hardly the misregistration of the subject in the image pickup visual field can be obtained.

Therefore, the heating medium heated by the solar heat collector unit 1 can be collected only for the heat-accmulative device 2 for airconditioner. In this way, the heat-accmulative device 2 for airconditioner is rapidly collected a thermal energy, a temperature of the heating medium is increased to enable an operation of airconditioning. Thereafter, a heat collection for the heat-accmulative device 4 for hot water feeding is performed. In this way, it is possible to improve an efficiency of operation of the air- conditioner.
