Title: Submarine check valve
Inventor: ENDOU HIROSHI
IPC: F16K15/04
Filed: 1982-01-20
Abstract: PURPOSE:To save machining and reduce working cost by using a rubber ball for a valve body and a casted hole provided in a casing for a valve seat. CONSTITUTION:During running of a pump, a valve body 1 comprising a rubber ball is pushed up by water flow and stopped against a stopper 2a provided in a valve casing 2. When the pump is stopped, the valve body 1 descends by its own weight to close a casted hole 3a provided in an upper casing 3. The ratio of the diameter of the casted hole 3a to that of the valve body is less than 0.7 so that the valve body 1 is prevented from being included in the casted hole 3a.

Title: Preparation of ester by modification lipase
Inventor: INADA YUUJI
IPC: C12N11/08
Filed: 1984-01-17
Abstract: PURPOSE:To make an enzymatic reaction in an organic solvent possible and to prepare a carboxylic acid ester by a modification lipase, by reacting a carboxylic acid with an alcohol in the presence of a specific modification lipase in an organic solvent to esterify it. CONSTITUTION:In the presence of a modification lipase obtained by reacting a lipase with an active derivative of a polyalkylene glycol containing a hydrophobic group at the end, a carboxylic acid is reacted with an alcohol in an organic solvent, it is esterified, or a carboxylic acid ester is reacted with another carboxylic acid or alcohol, so that it is subjected to ester exchange to give an ester. Since the modification lipase is modified with a straight chain comprising a substituted polyalkylene glycol having both properties of hydrophobic nature and hydrophilic nature, it is soluble in both water and an organic solvent, a high-order structure of lipase of its own is protected with the straight chain, and prevents deactivation caused by contact with the organic solvent.

Title: Sheet feeding device
Inventor: OKAWA KATSUHISA
IPC: B65H5/10
Filed: 1989-01-12
Abstract: PURPOSE:To prevent the trouble due to static electricity by judging the piled sheet height before and after taking out sheets and calculating the taken-out sheet quantity and changing the receiving/delivery position in each case where the sheet quantity is one or in superposed state. CONSTITUTION:Each measurement before and after taking out sheet from a tray is carried out by a height measurement device 2 for measuring the height of a plurality of sheets 11 placed on a sheet tray 5. The quantity of the taken- out sheets is calculated from the difference of the measurement values. When a judging device 3 judges that the quantity is one, operation is performed so that the sheet is transported to a receiving/delivery tray 6, while if the judging device 3 judges the superposed taking-out, operation is performed so that the sheets are transported to a discharge tray 7. Thus, even if the sheets are taken out in superposed state, the device is prevented from being stopped, and the taking-out work for the sheet which tends to he attached because of static electricity can be carried out in unmanned work form.

Abstract: PURPOSE:To eliminate the need for equipment such as high pressure pump and reduce consumption energy by installing a reverse osmotic membrane module in the deep sea bottom and making use of the difference between the water pressure in the deep sea and atmospheric pressure in the desalination apparatus of sea water. CONSTITUTION:In the case of desalinating sea water by a reverse osmosis method, a permeable membrane module 1 is installed in the deep sea bottom and one end of a vent pipe 2 of high pressure resistance is mounted to the water permeation side thereof. The other end of the pipe is protruded on the sea surface and sea water pressure and atmospheric pressure are applied to the permeable membrane module. Owing to the differential pressures thereof, fresh water is produced as permeated water form sea water and this fresh water is once stored in a storage tank 3, after which it is stored into the water storage tank 6 on the sea surface by a lift pump 4. When the deep sea of several hundred meters cannot be used, microbes and suspensions are filtered out by passing the sea water through a filter and the sea water is sent to the permeable membrane module after controlling its pH. For pressure insufficient portion, the energy of wind force or wave force is utilized.

Filed: 1993-01-20
Abstract: PURPOSE:To obtain a method of manufacturing a semiconductor device, wherein a semiconductor substrate is protected against warpage caused by a film stress, the device can be easily transferred, and a junction leakage can be restrained from occurring in the device. CONSTITUTION:A first metal film 13 is deposited on a semiconductor substrate 11 (b), and a second metal film 14 which warps the substrate 11 the same in direction and size as the first metal film 13 is deposited on the rear side of the substrate 11 (c). Thereafter, the metal film 13 is patterned (d), and lastly the second metal film 14 is removed (e, f). By this setup, stress imposed on a semiconductor substrate totals to zero, so that the substrate is hardly warped. Therefore, troubles that a semiconductor device is hard to transfer by a transfer device where a vacuum chuck is utilized and is increased in junction leakage can be eliminated.

Title: Automatic gain control circuit
Inventor: SANO YOSHIAKI
IPC: H03G1/00
Filed: 1978-01-27
Abstract: PURPOSE:To make it possible to amplify large-amplitude input signals with a small distortion by connecting a controlled stage, which lowers the gain by AGC operation when the amplitude of input signals is large, and an element, which amplifies signals with a small distortion only when the amplitude of input signals is large, to a load commonly. CONSTITUTION:Transistor T5 is provided in conventional intermediate frequency amplifying stage IF, and resistance R4 of T5 is made common to resistance R4 of T3 and T4. When the amplitude of input signals is increased and the AGC voltage in terminal  TA becomes large, T7 becomes conductive and the current flows to T5. Then, the current of T3 and T4 is reduced, and consequently, the gain of differential amplifying stages T3 and T4 is reduced. Meanwhile, since T5 is so connected that the gain may be prevented from changing due to the change of the AGC  voltage and the value of the element is so set that a strong negative feedback may  be caused by resistance R3, the gain is given as R3/R4 approximately.As a result,  large-amplitude input signals can be amplified with a small distortion only by T5.

Abstract: PURPOSE: To reduce the volume of a low pressure pump by returning the fuel spilled into an accumulator volume to a port before the closure of a valve member at the start of next repletion to the port of a distributor member. CONSTITUTION: Fuel from a low pressure pump 24 is supplied to a pump chamber 17 through an inlet 23, a groove 22 and a passage 21 in response to the setting of a throttle 25 by the rotation of a distributor member 10. When the groove 22 is separated from a port 23 and a passage 19 is aligned with an outlet 20, a plunger 16 is actuated by a cam ring 28 and fuel is delivered to an injection nozzle. When a sleeve 37 is actuated by the inward movement of a shoe 26 and a valve seat 36 is separated, fuel flows into an accumulator chamber 41 and the internal pressure of a pump chamber 17 drops rapidly. When the distributor member is further rotated, the passage 19 and the outlet 20 are moved apart, the groove 22 is aligned with another inlet 23. A roller 27 passes a top of the cam ring 28, and the plunger 16 is moved outwardly.  Fuel in the accumulator chamber 41 is returned to the bore 15 of the pump chamber 17 via a bore 43. In this way, it is possible to reduce the volume of the low pressure pump.
