Title: Production of high purity potassium hydroxide
Inventor: SUZUKI KOJI
IPC: C25B1/46
Filed: 1987-03-10
Abstract: PURPOSE:To stably produce high purity KOH contg. a small amt. of KCl as an impurity when KOH is produced, by electrolyzing an aq. KCl soln., by using an electrolytic cell provided with a specified cation exchange membrane and keeping the concn. of chlorate in the electrolytic soln. low during the electrolysis. CONSTITUTION:When an aq. KCl soln. is electrolyzed in an electrolytic cell provided with a diaphragm to produce KOH, a cation exchange membrane contg. fluorine is used as the diaphragm and the electrolytic cell is divided into cathode and anode chambers with the membrane. The membrane is a two-layered membrane consisting of a main layer of a perfluorocarbon polymer having sulfonic acid groups as a base layer and a sublayer of a perfluorocarbon polymer having carboxylic acid groups. The membrane is stretched in the electrolytic cell so that the latter layer faces the cathode chamber. Water permeates the cation exchange membrane by electroosmosis at 2.5-4.0mol. H2O/Faraday rate. The cation exchange capacity of the layer having carboxylic acid groups is 0.9-1.6 milliequiv. per 1g dry resin and the thickness is 80-300mum. The cation exchange capacity of the layer having sulfonic acid groups is 0.8-1.3 milliequiv. per 1g dry resin and the thickness is 10-40mum.

Title: Controller for speed of revolution of motor
Inventor: MAEHARA SHIGEJI
IPC: G03B27/50
Filed: 1988-03-07
Abstract: PURPOSE:To remove selection with respect to the turn off characteristics of a transistor and to prevent cost from being increased by increasing/decreasing the raising duty ratio of a motor with the aid of setting input from an outside, so that the individual difference of the transistor is removed. CONSTITUTION:When a simulation mode is set by turning on a dip switch SW 1, the value of the raising duty ratio D stored in the memory area MA 1 of a RAM 13 is changed to an inputted value by the key operation of a console panel 9. In this manner, after finishing the assembling operation of a copying machine main body 21 or at the time of maintenance, the simulation mode is carried out, and a voltage duty ratio impressed to a driving circuit is changed by the key operation in such a manner that the pulse of the driving voltage impressed to the motor M1 becomes a prescribed duty ratio. Thus, a work to select the characteristic of electric parts such as the transistor, etc., constituting the driving circuit is omitted; so that the increase of the cost is prevented and also a stabilized producing state is maintained.

Title: Automatic electric pump
Inventor: HATSUTORI AKIYOSHI
IPC: F04B49/06
Filed: 1981-04-08
Abstract: PURPOSE:To eliminate the foreign feeling to the human body due to the temperature change of the shower, by determining the relay selection to the pressure switch by means of a relay to be functioned through the opening/closing of a flow sensor thereby limiting the pressure range. CONSTITUTION:The first and second pressure switches 7, 8 are connected in parallel and the relay selection to the pressure switches 7, 8 are determined by a relay 9 in a dashed line circle to be operated through the opening/closing of a flow detector 5. The incorrect temperature change of the shower hot water has been caused by the fact that the cool water will vary by DELTAQ1 due to the ON, OFF pressures of the pressure switch and the pressure variation of P1, P3. Assuming the cool water variation which causes no foreign feeling to the human body is DELTAQ2, the open pressure and the close pressure of the second pressure switch 8 are made P1, P2 respectively to bring the cool water variation into Q2 thus to eliminate the foreign feeling.

Title: Writing circuit for junction destructive p-rom
Inventor: KAWAKAMI KENJI
IPC: G11C17/18
Filed: 1979-05-02
Abstract: PURPOSE:To make programming in a package state possible by suppressing the operation of a PNPN element with an extremely small current by grounding the base of the NPN transistor of the PNPN element via the element. CONSTITUTION:The base of NPN transistor TrQ2 constituting the PNPN element is grounded via resistance R3. As a result, an extremely small current such as a leakage current, when appearing at the collector of PNPTrQ1, flows to the ground via resistance R3 without flowing to the base of NPNTrQ2 to turn the PNPN element ON. Therefore, not less than two P-ROM ICs whose outputs are connected mutually can be programmed in the package state.

Title: Disk library device
Inventor: OTA SHUICHI
IPC: G11B17/22
Filed: 1990-03-07
Abstract: PURPOSE:To greatly lighten the processing burden of a host device by storing a cartridge allocation table, and converting automatically a logical address into a physical address. CONSTITUTION:A system control part 31 refers to the cartridge allocation table, and reads out the physical address corresponding to the designated logical address, and takes out an optical disk cartridge CR stored in that physical address, and loads it in an optical disk driving device 5, 6. Then, after the movement is finished, it changes the contents of the physical address corresponding to the logical address at that time to the physical address after the movement. Accordingly, since the host device can designate an objective optical disk (cartridge CR) by only designating the physical address, the processing burden of a part to access the optical disk can be lightened.

Filed: 1985-03-18
Abstract: PURPOSE:To simplify a processing by performing the comparison of a largeness and a smallness and a matrix arithmetic and judging whether a point is included in a polygon, or not. CONSTITUTION:After an initialization is carried out, respective coordinate values of summits Pi and Pitl of a polygon are loaded in an M register and an N register so as to have Y coordinate value Ny being above My. It is examined whether a test point's Y coordinate value Py has the relation of Ny>=Py>=My. When the result is yes, an outer product PMXPN of vectors PM and PN connecting to both ends respectively of a side selecting the test point P is obtained. Thereafter, whether the code of a Z coordinate of the obtained outer product is positive or not is judged. In the case of a positive, a counting value C is increased by 1. In the case of the judging result being no, it is examined whether i=E or not, on all the sides of the polygon, it is judged whether the above-mentioned processings are carried out or not. In the case of yes, it is judged whether the counting value is an odd number or not. In the case of the odd number, it is judged that the test point P is present in the polygon, and in the case of an even number, it is judged that P is outside and the inclusion judging of the test point is completed.

Title: Light emitting semiconductor device
Inventor: MORI MITSUHIRO
IPC: H01S5/042
Filed: 1984-03-23
Abstract: PURPOSE:To suppress the current extension of a light emission and to reduce the thermal resistance of an element by providing a low resistance layer which is larger in area of the portion opposed to an active layer than the semiconductor portion which is contacted with a substrate side electrode. CONSTITUTION:An N type active layer (N or P type), P type and N type crystalline layers 22, 23, 24, 25 are continuously formed on the crystal layer (N type conductive layer) 21 having a light transmitting wide fobidden band width. A P<+> type layer 26 is formed by diffusing Zn or Cd, and a P<+> type 261 is formed by a lateral abnormal diffusion. P type of substrate side and N type ohmic electrodes 271, 272 of light emitting side, internal light emitting window 28 are formed, and an optical fiber is mounted at this portion. A current is flowed through 26 to the layer 23, and the 231 becomes the light emitting region. Since the electrode 271 has a large contact region, the contacting resistance can be reduced. When the light emitting diode is energized forwardly, the P-N junction is biased reversely, and the extension of the current can be prevented without using an insulating film.
