Filed: 1991-04-26
Abstract: PURPOSE:To develop intial strength and to improve the compressive strength, flexual strength and watertigheness by regulating the pH of a specified soln. with aq. NaOH soln. and then passing the soln. through the bed of an acidic cation-exchange resin to remove alkali ion. CONSTITUTION:An alkali silicate is diluted with water to obtain a soln. contg. 1000-10000mg/l of Si. About 0.5N NaOH is added to the soln. to regulate the pH to 12-13, the soln. is then passed through the bed of an acidic cation- exchange resin (e.g. 'Amberlite IRC-50(R)') to adsorb Na<+> ion on the resin to produce a dissolved silica-contg. liq. concrete admixture with the solute consisting essetially of Si. The soln. passed through the resin bed, as required, vaporizes the contained water, or the soln. is concentrated by reverse osmosis to control the Si content to 10000-50000mg/l, hydrochloric acid, acetic acid, etc., are added to the soln. to adjust the soln. to <=pH2.0, and a dissolved silica- contg. concrete admixture is produced.

Title: Bi-polar type transistor
Inventor: AMAMIYA YOSHIHITO
IPC: H01L21/331
Filed: 1981-11-25
Abstract: PURPOSE:To suppress the positive feedback effect resulting in the prevention of the generation of the secondary breakdown, by so providing a metallic electrode as a base electrode on a base region so as to form a Schottky junction. CONSTITUTION:The P type base region 2 is formed on an N<+> type semiconductor region 1 as a collector region, and an emitter region 3 is formed in the region 2. On the region 2, the metallic electrode 6 as the base electrode is so provided as to form a Schottky junction 10. In this constitution, when the base current passing through an electrode 6, the junction 10, the region 2, a P-N junction 8, a region 3 and a metallic electrode 7 flows from a bias source, based thereon, the collector current flows between metallic electrodes 5 and 7. However, the junction 10 functions so as to allow the voltage-current characteristic thereof to possess sufficient saturation characteristic, and therefore the base current is restricted. Therefore, the positive feedback effect wherein the base current increases locally is suppressed, and accordingly the extremely large collector current does not flow. Thereby, P-N junctions 8 and 9 are prevented from breakdown.

Abstract: PURPOSE: To have a high efficiency conversion of fluid energy into the rotation energy by allowing an internal gear and a planet gear to revolve at the same speed in the opposite directions and by rotating thereby the pinion shaft at a speed increase rate of twice approximately.  
     CONSTITUTION: Fluid energy turns a propeller shaft 7 and 10 counterclockwise and clockwise, respectively, and the rotations are transmitted to the pinion 5 through an internal gear 6 and a planet gear 8 to cause the shaft 3 turning clockwise. The shaft 3 revolvs at a speed determined from the sum of the number of revolutions of the propeller shaft 7 and that of the propeller shaft 10, multiplied by the number of cogs of said internal gear 6, divided by the number of cogs of the pinion 5 and added by the number of revolutions of the propeller shaft 10, i.e. approximately twice as quickly, and thus the fluid energy can be converted into rotational energy at a high efficiency.

Abstract: PURPOSE:To prevent the positional deviation of a ceramic tip and to facilitate the removal of flashes on small projecting parts by arranging plural small projecting parts at the side wall of ceramic tip incorporating part and pouring basin parts around the incorporating part in a casting metallic mold so as to produce flashes on the projecting parts. CONSTITUTION:As the movement of the ceramic tip 10 is regulated by the small projecting parts 19, 20, 21, 22 arranged at the side wall of a ceramic tip incorporating part 11 in the casting metallic mold 2, at the time of pouring molten into the cavity 5 of a locker arm, the bounce of the ceramic tip 10 is not developed. Therefore, the positional deviation such as fall-down or inclination of the ceramic tip 10 to the locker arm is not developed and the development of remaining surface as cast in grinding the slipper surface or the development of defect chamfering, are prevented. Further, at the time of mechanically separating the projecting parts formed of the pouring basin parts 12, 13, 14, 15, as the flashes are produced on the projecting parts, the flashes are easily removed.

Filed: 1989-07-20
Abstract: PURPOSE:To shorten the time from input to display by quickly performing the processing of recognition of the state input from a sensor switch and display of state data in each input/output control part. CONSTITUTION:The state signal from the sensor switch is recognized by keeping the input state effective for a certain time in an input circuit of an input/output control part 5, and the result is stored in an input/output control circuit 7 to perform the state management and is reported to not only an input control circuit 6 but also an output circuit 9 to display the state on a display part 10. Consequently, the processing of input and display is performed in the input/ output control part 5. A central processing part 4 scans the state with each input/output control part as the unit, and the instruction of scan indication is decoded by an output control circuit 8 of each input/output control part 5, and the input control circuit 6 receives this instruction to transmit state data to the central processing part 4 through a bus. Thus, the time from input to display is shortened to reduce the load of the central processing part.

SOLUTION: A silicon steel slab, containing, by weight, 0.010-0.020% Al and also containing preferably 0.015-0.065% C, is heated to <=1260 deg.C and hot- rolled. Then, hot rolled plate annealing, consisting of short-time annealing at <=1000 deg.C for <=60sec, is applied to the resultant hot rolled plate. This hot rolled plate is cold-rolled once or is cold-rolled two or more times, while process- annealed between cold rolling stages, to final sheet thickness. It is preferable to perform this cold rolling by using a tandem mill at >=100 deg.C. The resultant cold rolled sheet is subjected to decarburizing annealing, and then, after the application of a separation agent at annealing, composed of MgO, etc., final finish annealing is carried out.

Title: Semiconductor substrate and manufacture thereof
Inventor: KUSAKA TERUO
IPC: H01L21/76
Filed: 1984-09-11
Abstract: PURPOSE:To prevent a substrate from warping by a method wherein the polycrystalline semiconductor layer, which is the body supporting the substrate, is caused to be exposed to the primary surface of the substrate, grooves are provided in the polycrystalline semiconductor layer, the polycrystalline semiconductor inside the grooves are oxidized and the oxide thus formed fills up the grooves. CONSTITUTION:The principal surface of a polycrystalline semiconductor sub strate 1 is locally covered by a mask 7 and then a groove 8 is formed therein. Next, after the removal of the mask 7, a polycrystalline semiconductor thin film 9 with a thickness (t) is provided. Next, the thin film 9 is subjected to oxidation for the formation of a polycrystalline semiconductor oxide film 10. The volume of the resultant oxide film 10 is quantitatively larger than the film 9 before oxidation. The enlargement results in the filling-up of the groove 8. The increase cannot be accomplished with ease because it takes inside the groove 8, which causes some stress to mount inside the groove 8. The stress becomes a pull stress, while counterbalancing the pull stress present in the rear side. As the result, a substrate does not suffer from warpage during a heat treatment process.
