Inventor: KODAMA SATOSHI
IPC: B08B3/02
Filed: 1987-01-23
Abstract: PURPOSE:To efficiently perform washing by minimizing the use amount of a washing solution, by a method wherein the contamination state of the washing solution of a washing solution spray apparatus is always measured and, when said contamination state reaches a predetermined one, the discharge of the contaminated solution and the supply of a new washing solution are performed. CONSTITUTION:A contamination degree measuring apparatus 20 is provided to a washing solution spray apparatus 1 and the mixing amount of the contaminant mixed in a washing solution, that is, the substance such as the release agent or low-molecular unreacted resin removed from a plastic molded product 8 mixed in the washing solution is always measured. When the control apparatus 21 connected to the contamination degree measuring apparatus 20 detects that the mixing quantity of the contaminant reaches required one by continuous washing treatment, a liquid discharge pump 17 is operated by the signal from the control apparatus 21 to discharge a preset amount of the washing solution to the outside from the spray apparatus 1. In the same way, a fresh washing solution supply pump 23 is operated and a new washing solution is supplied to the apparatus 1 from a tank 22 in the same quantity as the discharged quantity.

Title: Rotary disc type shutter grid device
Inventor: KASHIHARA HIDECHIYO
IPC: G21F3/00
Filed: 1978-02-09
Abstract: PURPOSE: To obtain a clear picture image, by providing a slip part and a shielding part on a rotary disc, and using the shielding part as the shutter.  
     CONSTITUTION: A rotary disc type shutter grid 7 is constituted with a shielding part 8 and a radial slit part 9, and is disposed between the film 1 and the object being inspected 4 in a manner that the rotary shaft thereof may be directed to the X-ray focal direction of an X-ray generation apparatus 5. In this state, the film 1 is shielded by the shielding part 8. By rotating the shutter grid 7 and operating the X-ray generation apparatus 5, the X-ray transmitted from the slit 10 and the object being inspected 4 is radiated on the film 1 to take an exposure. After radiographing, the film 1 is again shielded by the shielding part 8. Thus, the shutter grid 7 may be reduced in thickness and the distance between the object being inspected 4 and the film 1 may be shortened. Hence the intended purpose may be achieved.

Title: Dehydration and defatting from food
Inventor: KOUDOU KEIUN
IPC: A23L5/20
Filed: 1983-01-31
Abstract: PURPOSE:A food product containing water and lipid is heated together with a solvent under reduced pressure and the solvent is separated from the distillate and refluxed to remove the solvent containing lipid, thus the lipid in the food product is kept low to give a food product storable for a long period of time without taste deterioration. CONSTITUTION:A food product to be treated such as fish is placed in a cage of stainless steel 2 and put into the dehydration and defatting tank 1, then tightly sealed. As the tank 1, lipid concentration tank 4, condenser 6 and fractionation column 9 are evacuated, a solvent such as ethyl acetate is fed from the tank 11 into the defatting tank 1. When the solvent overflows from the tank 1 through the valve 32 and reaches a certain amount in the tank 4, the valve 31 is closed and the tanks 1 and 4 are heated  to effect extraction of lipid in the food product as well as azeotropic distillation at a specific ratio with the water in the food, thus a part of the solvent containing lipid is transferred through the valve 32 to the tank 4. In the meantime, the condensed distillate  6 is separated into water and solvent in the separator 9 and only the solvent is recovered, sent through the valve 36 to the tank 1 for refluxing. When dehydration and defatting are completed to keep the lipid concentration low in the tank 1, the whole solvent in the tank 1 is made to flow down to the tank 4, then the distillation is effected under reduced pressure to remove the solvent.

Title: Automatic voltage adjuster
Inventor: KUROKI AYANORI
IPC: H02M3/335
Filed: 1981-02-05
Abstract: PURPOSE:To obtain an automatic voltage adjuster having small capacitance with high efficiency, by driving a switching circuit according to the fluctuation of the output voltage to rectify the input voltage and superposing the compensating voltage according to the degree of fluctuation on the input voltage of a control transformer. CONSTITUTION:The input supplied through a bus 1 is supplied to a load 5 via a control transformer 11 and a filter 2. With the fluctuation of the output voltage of the filter 2, a control circuit 6 drives a switching circuit 13 and converts the input given from a power supply transformer 10 through a rectifier 14 to produce the compensating voltage proportional to the degree of fluctuation of the output voltage. In case the output voltage drops less than a prescribed level, the compensating voltage is superposed with in-phase on the bus input voltage of the transformer 11. When the output voltage increases higher than the prescribed voltage, the compensating voltage is superposed in adverse phase on the transformer 11 to keep the output voltage at a prescribed level. In case the degree of voltage fluctuation exceeds the prescribed level, the reactive electric power produced at the transformer 11 is fed back to a transformer 10 via a feedback circuit 15. As a result, the electric power is saved to reduce the power capacitance of each mechanism related to the control function.
