Patent JP-S5832902-A (JP)
Title: Steam turbine
Inventor: KITAZAWA MORIKAZU
IPC: F01D9/02
Filed: 1981-08-20
Abstract: PURPOSE:To withstand the increased temperature and increased pressure of main steam requirements by forming a high pressure outside casing in a barrel-type structure divided in two in the axial direction and with no horizontal flange in the high pressure section of a high powered steam turbine. CONSTITUTION:Double discharge type nozzle boxes 4c, 4d are arranged at both ends of a high pressure stage group. High pressure outside casing 2a, 2b have no flange and are formed in a barrel-type structure divided in two in the axial direction. The steam passing a nozzle 4b and blade 5b flows between the outside casings 2b, 2a and an inside casing 3, and mixing with the steam flown out of the first high pressure blade 5a, then flows into the second high pressure nozzle. Therefore, the high pressure inside casing 3 is invariably kept at a higher pressure at its outside, thus its strength design is made very easy. Accordingly, the steam turbine can withstand an increase of main steam requirements, and the operability can be improved.

Title: Crosslinked-polyethylene-insulated aerial cable
Inventor: IJIRI YASUO
IPC: H01B7/28
Filed: 1987-05-26
Abstract: PURPOSE:To prevent forming a recessed part on a stranded wire copper conductor by providing the first layer containing triazole copper rust preventives and the second layer containing a proton capture agent, and making the second layer to be in the conductor side. CONSTITUTION:A layer of a separator tape 2 composed of the first layer 21 containing triazole copper rust preventives and the second layer 22 containing a proton capture agent is provided on the immediate upper part of a stranded wire copper conductor 1 with the layer 22 made to be in the conductor 1 side, furthermore, a crosslinked-polyethylene-insulated layer is provided on the tape 2 layer. Consequently, even if a non-crosslinked-polyethylene component substance layer is heated at a high temperature in order to crosslink and thereby a triazole compound in the layer 21 vaporizes heavily, a sudden reaction between a triazole compound vapor and copper on the conductor 1 surface is temporarily hindered as a proton capture agent in the layer 22 captures proton which is to be catalyzer. This prevents forming a recessed part on the conductor 1.

Title: Consumable electrode type pulse arc welding machine
Inventor: HIRASAWA KAZUNARI
IPC: B23K9/09
Filed: 1980-09-17
Abstract: PURPOSE: To decrease the frequencies of occurrence of short-circuiting, and maintain arc voltage always correctly by increasing welding voltage immediately upon occurrence of short-circuiting, decreasing the same when there is no more short- circuiting thereby automatically controlling the welding voltage in a narrow range at all times.  
     CONSTITUTION: A welding arc current waveform Va is applied from a short-circuit detecting circuit 1 via a Schmitt circuit 2 and an inverter 3 to an up-down counter 4, and is applied via a D/A converter 8 to a control circuit 9. At this time, the output of the counter 4 increases every time when short-circuiting occurs, and this signal forces a control circuit 9 to widen the conduction angle of a thyristor, thereby increasing welding output voltage. When the welding arc is released from the short- circuiting, the voltage outputted from the circuit 2 to a timer circuit 5 rises to a high level and a transistor Tr 1  conducts so that a capacitor C 1  is charged. If the next short-circuiting does not occur, the pulse generated in the timer circuit is applied to the down terminal of the counter 4, and the output of the circuit 9 drops, whereby the welding output voltage is decreased.

Title: Production of ceramic sintered product having function for activating water
Inventor: DOYAMA MASAO
IPC: C04B35/64
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a sintered product having a function for activating water by carrying out the sintering treatment of a process for producing the ceramic having the function for activating the water, capable of preventing the fusion of the ceramic molded product and the generation of defective products and clearly improving effects for inhibiting the generation of rust and microorganisms. SOLUTION: This method for producing a ceramic sintered product having a function for activating water comprises crushing natural rocks containing silica, alumina, sodium oxide, potassium oxide, magnesium oxide, calcium oxide and iron oxide as components, filling an alumina vessel, etc., with the obtained spherical crushed products, sintering the filled spherical products under vacuum in a vacuum oven or in a hydrogen atmosphere and subsequently naturally cooling the sintered product. Since the removal of oxygen atoms from the surfaces of the sintered products is thereby accelerated, a treating temperature can be lowered, and the obtained ceramic can be kept away from its melting. Double effects that the effect is increased at the same sintering temperature can be expected, since the local release of oxygen atoms is increased.

Filed: 1981-08-20
Abstract: PURPOSE:To easily operate a camera, by automatically switching a photometric mode of a camera to partial photometry (spot photometry) from a photometric mode for regular photographing, by being interlocked with an EE locking opration, so that photometry of luminance of a main object to be photographed being under back light can be executed in a state that the camera is placed at the ready at a photographing position, at the time of EE lock photographing. CONSTITUTION:When an EE lock operating member is operated, a switch SW9 is turned on, an analog switch AS1 conducts, AS2 is inhibited, and to an OP amplifier OP2, instead of an output of a mean photometric circuit, an output of a partial photometric circuit, that is to say, an output of a photodetector SPC1 is inputted. As a result, the output of the OP amplifier OP2 becomes voltage corresponding to a shutter second time value based on the output of the partial photometric circuit. On the other hand, when the switch SW9 is turned on, an output of an inverter I2 becomes an H level, a specific circuit consisting of a resistance R10 and a capacitor C1 is operated, and after a prescribed time has passed, an output of an invertor I3 becomes an L level, an AND gate A3 is inhibited, and counting operation by a counter CN1 is inhibited. Accordingly, a digital value corresponding to a shutter second time based on partial photometry is stored in the counter CN1, irrespective of a release operation.

IPC: G11B20/10
Filed: 1983-07-19
Abstract: PURPOSE:To minimize the reduction of effective memory capacity for a rotary data memory having a fixed length type format by providing a sector having different length from other sectors at a place immediately after an index point and using this sector as a sector exclusive for read/wire diagnosis. CONSTITUTION:The sector layout of a data track is shown like (e) by an index signal (a), the 1st sector pulse (b) and a sector pulse (c). The count set value of the 1st sector pulse generating circuit 100 is set smaller than that of the 2nd sector pulse generating circuit 200. As a result, the width of the sector 0 is smaller than sectors 1-N. For example, the number of record bytes of a track, the number of normal data record sectors, the length of the sector 0 and sectors 1-32 are set at 20,000, 32, 96 bytes and 622 bytes respectively. As a result, the length of the sector 0 equals just to 96/20,000(=0.0048) length of a track. Therefore the total reduction of memory capacity of a medium equal just to 0.48%. Thus it is possible to secure a record area exclusive for write/read diagnosis for all tracks.
