Title: Magnetic erasing device
Inventor: SOGA TAKASHI
IPC: G11B5/024
Filed: 1986-01-14
Abstract: PURPOSE:To simplify the circuit constitution of a magnetic erasing device for miniaturization together with high reliability, by using a magnetic head for recording, reproduction and erasing properly with switching through the ON/OFF operations of a semiconductor switch and the control of a DC constant current source carried out by a current mirror. CONSTITUTION:The reference current I0, i.e., a DC current which is reduced gradually is produced by a current/voltage conversion circuit II with input of an erasion command 10 of a terminal A. Then the current I0 flows to a reference transistor Tr3 of a switch over circuit III. Here both Tr6 and Tr7 are turned on and off alternately for each switch of polarity by a switch control circuit V. Then the collector currents I1 and I2 equal to the current I0 flow alternately owing to the current mirror effect. Thus an erasion current flows to a coil 4 of a magnetic head 3 for execution of erasion. While no current I0, I1 nor I2 are produced with input of a recording/reproducing command 11 of the terminal A and both Tr6 and Tr7 are turned on by a switch control command. Then the recording and reproducing signals are transferred via a recording/reproducing amplifier 13 and a transformer 12. Thus the recording and reproducing actions are carried out.

Abstract: PURPOSE: To hydroformylate an olefin industrially and advantageously, in a specific catalyst solution, by taking out part of the catalyst solution in the reaction zone, crystallizing the catalyst, and recycling the crystallized triarylphosphine to the above-mentioned reaction zone.  
     CONSTITUTION: An olefin is hydroformylated in a catalyst solution containing a complex catalyst of a noble metal selected from Group VIII triarylphosphine, an excess  of a triarylphosphine and a reaction solvent. The resultant aldehyde is separated  and obtained by evaporation out of the reaction zone, and simultaneously the  catalyst solution is partially taken out of the reaction zone, preferably in the triarylphosphine concentration of 1W60wt%, as a waste catalyst solution, which is crystallized, preferably at -78°W80°C. The triarylphosphine thus crystallized is advantageously and selectively separated and recovered, without using a substance poisoning the catalyst or corroding the reactor. The resultant triarylphosphine is then  preferably purified, and recycled to the reaction zone mentioned above.

Title: Crushing and pressurized feed device for excrement
Inventor: NAMIMATSU MINORU
IPC: E03D5/00
Filed: 1994-01-20
Abstract: PURPOSE:To prevent an air pocket from being formed in a soil pipe by keeping the soil pipe and a soil reservoir continuous to each other via a communication tube. CONSTITUTION:A communication pipe 10b for keeping a soil pipe 3 continuous to a soil reservoir 6 is positioned higher than the maximum level of flushing water running in the pipe 3. Excrement flushed and discharged with water fed from a flushing water tank 4 is carried to a crusher 5 via the pipe 3 and pulverized. In this case, the air in the pipe 3 is released to the atmosphere from the vent 10a of the reservoir 6 via the communication pipe 10b. Also, when water containing pulverized excrement is pumped up with a submerged pump 7 and discharged from a discharge pipe 8, the fresh air flows into the reservoir 6 via the vent 10a and as well into the soil pipe 3 via communication pipe 10b. As a result, the occurrence of differential pressure between the reservoir 6 and the soil pipe 3 can be prevented and a trap in a toilet 1 can be maintained.

Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To stably form a shadow mask with high quality without relating uniform or un-uniform friction resistance between a raw material of the shadow mask, an outer punch and a die. SOLUTION: An inner punch 54 and an outer punch 55 are advanced at the same time to the inside of a die 33 through a shadow mask raw material 12 and pressed to a knock-out 34.

Title: Arithmetic circuit
Inventor: DOI KOJI
IPC: G06F7/76
Filed: 1990-01-12
Abstract: PURPOSE:To obtain an arithmetic circuit which can maintain the interchangeability with the conventional device types with no increase of the processing value despite the increase of the data bit width by adding the hardware to the arithmetic circuit to mask the input signal of an ALU. CONSTITUTION:The output of a multiplier 1 passes through a mask circuit 2 before input to an ALU 3. The circuit 2 masks a specific bit of an input signal with the control signal received from a mask circuit control register 4. In such a case, the register 4 is designated so that the lower 16 bits are masked into '0'. Therefore the lower 16 bits are masked into '0' out of the 32-bit data for the output signal of the circuit 2. Thus the data are totalized by a totalizing register 5 and therefore this totalizing result is similar to that of a digital signal processor DSP. As a result, the other necessary processing operations can be limited down to just a single one where a mask is designated to the register 4.

Abstract: PURPOSE:To prevent a die life from being shorten and improve the accuracy of metal flow control by irradiating locally the circumferential part of a forming gap of an extrusion die with heating laser beam for controlling metal flow from the front part of an extruder. CONSTITUTION:A trial extrusion is performed by a die 7 having a forming gap 7a corresponding to the cross sectional shape of a die material E so as to prepare data on an oscillating starting point of heating laser beam, an irradiation position and an irradiation area of heating laser beam, etc., in accordance with the shape and size, etc., of the die material E to be worked. The irradiation position of laser beam is decided with a neighboring part of a forming gap slow in metal flow speed as a reference. The regular working is performed according to the data, a heating laser beam oscillator 15 is actuated at a prescribed time point and extrusion is carried out while a prescribed area on the circumference of a forming gap on the rear of the die 7 is locally heated. Consequently, a deformed die material excellent in shape accuracy can be extruded. Further, local heating can be performed concentrically within a very narrow range at need and metal flow control can be improved in accuracy, too.

Title: Optical switch array
Inventor: IGUCHI TOSHIYUKI
IPC: G02F1/03
Filed: 1982-01-18
Abstract: PURPOSE:To obtain an inexpensive optical switch which is easy to produce, by utilizing the change of the refractive index due to the variance of temperature in a transparent material to form an optical switch array. CONSTITUTION:When a parallel luminous flux LP is made incident from the side of a mask 30, a part of the light is incident from a small window of the mask 30. If power is not supplied to an upper part heating electrode 50U-i, the light incident from a small window 30U-i goes straight as it is and is intercepted by a photoconductor 20 because a transparent photoconductor 20 has a uniform refractive index distribution near the electrode. If power is supplied to the electrode 50U-i, the photoconductor 20 is heated by the Joule heat, and the optical path of the light is bent by the generated uneven distribution of the refractive index, and the light is emitted from a small window 40-2i of a mask 40. Similarly, when power is supplied to a lower part heating electrode 50L-i, the light incident from a small window 30L-i of the mask 30 is emitted from a small window 40-2i-1 of the mask 40. Respective arrangements of upper and lower part heating electrodes are set properly to improve the resolving power without generating the crosstalk.
