Title: Reverse osmosis membrane type water generator
Inventor: KAWAGUCHI HIROSUKE
IPC: B01D61/08
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To operate a reverse osmosis membrane device demonstrating adequate performance from the start and to prevent troubles including the breakage of the device by keeping the opening of a needle valve at the opening stored in an opening storage means for a given time after the reopening of the operation of a pressure pump. SOLUTION: During the operation of a reverse osmosis membrane type water generator 10, a pressure detection means 54 detects the liquid pressure of a raw water channel 40, and an introduction side pressure control means 78 controls the opening of a needle valve 64, the passage opening of a concentrated water channel 58, based on the detected value of the pressure detection means 54 to feedback-control the pressure to be the liquid pressure of the raw water channel 40. Opening storage means 66, 84 store the opening of the needle valve 64 at the end of the operation of the water generator 10. An initial opening control means 82 keeps the opening of the needle valve 64 at the opening stored in the storage means 66, 84 for a given time after the reopening of the operation of a pressure pump 38.  In this way, adequate performance of a reverse osmosis membrane device 46 is demonstrated from the start of operation, preventing troubles such as the breakage of the device 46.

Title: Manufacture of mos semiconductor device
Inventor: TANAKA HIROYUKI
IPC: H01L21/265
Filed: 1987-10-16
Abstract: PURPOSE:To decrease the quantity of movable ions, to prevent the degradation of characteristics, and to enhance the reliability of a device by employing a specific process in which a high temperature annealing is performed before or after the introduction of P-type impurities into a polycrystalline silicon layer. CONSTITUTION:A polycrystalline silicon layer 14 is deposited on the surface of a gate oxide film 13 using a CVD method. Subsequently, boron or BF2 ions as P-type impurity ions are implanted into the polycrystalline silicon layer 14 to introduce P-type impurity ions into the polycrystalline silicon layer 14. Next, a high temperature annealing is performed in the atmosphere of N2 gas as an inactive gas at a temperature of 900-1000 deg.C in order to activate the polycrystalline silicon layer 14. As the result of the annealing process being performed, the grain size of the polycrystalline silicon layer is enlarged so that Na ions are prevented from diffusing and the Na ions do not reach the gate oxide film 13. Accordingly, both the variation of VT (AC inverse voltage) and the lowering of gm are effectively prevented.

Title: Camera with zoom device
Inventor: TANAKA YASUHIKO
IPC: G02B7/10
Filed: 1989-10-04
Abstract: PURPOSE:To eliminate confirmation when shifting a photographing lens to a telephoto edge and a wide-angle edge by directly shifting the photographing lens to the telephoto edge and the wide-angle edge for advancing and retreating the lens in an optical axis direction by not only zoom drive but without stopping the lens on the way. CONSTITUTION:When a TW direct operating part 12 is operated, the present position of the photographing lens is detected by an encoder 16 and the detected position is compared with the prescribed position. When the photographing lens is on the telephoto side than the prescribed position, the photographing lens is shifted to the wide-angle edge position without stopping on the way by the rotation of a motor 20, and when the lens is on the wide-angle side than the prescribed position, the photographing lens is shifted to the telephoto edge position without stopping on the way. When a TW zoom operating part 12 is operated, the photographing lens is zoom-driven by the rotation of the motor 20 and is stopped at the desired position. Thus, a photographer is prevented from being irritated and from missing a shutter chance.

IPC: C07C69/732
Filed: 1991-09-10
Abstract: PURPOSE:To obtain the subject compound in high purity and yield by treating a reaction product with a specific solvent, thereby removing impurities in high efficiency. CONSTITUTION:An alkyl acrylate is made to react with an aqueous solution of formaldehyde containing methanol in an organic solvent compatible with water in the presence of a tertiary amine, preferably 1,4- diazabicyclo[2,2,2]octane, pyrrocoline or quinolizine. The obtained 2-(1- hydroxymethyl)acrylic acid alkyl ester (RHMA) is extracted with an organic solvent incompatible with water (e.g. toluene, xylene or chloroform) and the solvent is distilled off from the extract. The obtained crude RHMA is dissolved in water and the impurities are extracted and removed with a solvent selected from petroleum ether and 5-8C hydrocarbons. A proper amount of an alkali metal or alkaline-earth metal salt is added to the aqueous layer obtained by the former process and the RHMA is separated by salting-out.

Abstract: PURPOSE:To prevent the intrusion of dust from an insertion hole easily at the time of using a circuit breaker without housing an accessory in a recessed part for housing an accessory of a breaking mechanism by attaching a seal to the bottom surface of the recessed part to seal an actuator insertion hole. CONSTITUTION:A breaking mechanism is built in a breaker case 1, which consists of a base 1a and a main cover 1b fixed to this base 1a. A recessed part 3 for housing an accessory of the breaking mechanism is formed in the surface 101 of the main cover 1b opposite to the base 1a, and an auxiliary cover 7 for sealing this recessed part 3 is fitted to the main cover 1b. An actuator insertion hole 4 for coupling an actuator of the accessory with the breaking mechanism is formed in the bottom surface of the recessed part 3 to form a circuit breaker. At this stage, a seal 9 is attached to the bottom surface of the recessed part 3 to seal the actuator insertion hole 4. Intrusion of dust into the breaker case 1 from the insertion hole 4 is thereby eliminated even in the case where the circuit breaker is used without fitting the accessory to the recessed part 3.

Title: Transistor circuit
Inventor: MIURA MASAMI
IPC: G05F3/22
Filed: 1989-10-06
Abstract: PURPOSE:To eliminate a different power source and to easily obtain a power source having high relative precision by forming a prescribed negative feedback circuit, and converting an input voltage into a voltage level generated with a voltage reference point to output it. CONSTITUTION:The collector current of a transistor TR Q1 is decided in correspondence with a voltage given to a terminal C. Then, the collector current of TR Q4 is set to a value almost equal to the collector current of TR Q1 by the negative feedback circuit which is connected after the collector of TR Q1 and is constituted of TR Q2, a resistor R2, a constant power source I0, TR Q3, a resistor R3, TR Q4 and a resistor R4. Namely, the input voltage VCA of the terminal C impressed by a ground potential reference is converted into the voltage VBD between a power source (terminal B) and a load terminal D and outputted. Consequently, the second power source of high relative precision with the first power source can easily be obtained by permitting the power voltage to pass through the transistor circuit when the first power source of the ground potential reference is present.

Abstract: PURPOSE:To enable measurement with high reliability by determining the concn. of a desired component which eliminates the influence of a chyle component and the absorbancy of the main absorption wavelength coincident with the concn. of the desired component by a two wavelength method using the main absorption wavelength and auxiliary absorption wavelength. CONSTITUTION:A specimen is housed in a reaction vessel and an analysis reagent is injected therein. The absorptivities ASPlambda1, ASPlambda2 at the main absorption wavelength lambda1 and the auxiliary absorption wavelength lambda2 are measured and the concn. of the component to be detected in the specimen, i.e., the concn. CSP in the state of contg. the chyle component is determined by the two-wavelength method. The absorptivity Ailambda1 at the main absorption wavelength lambda1 of the specimen in which only the desired component is included is determined in accordance with the result CSP of the measurement. Since this value indicates the absorptivity at the main absorption wavelength lambda1 of only the desired component without contg. the chyle component, the concn. of the chyle component in the specimen is determined from the difference between ASPlambda1 and ASPlambda2. The high-reliability measurement is thus enabled without requiring a specific reagent.
