Abstract: PROBLEM TO BE SOLVED: To eliminate the need for the recirculation of a reactional mother liquor by bringing a crystal stream of a salt of a strong acid produced in a reactor evaporator-crystallizer into countercurrent contact with a saturated saline solution of a salt in a leg part of a water column and washing the crystal stream of the salt of the strong acid. SOLUTION: An NaCl/NaClO3 brine prepared in a tank 1 at -5 to +90 deg.C is metered, fed to the head 2a of a container 9a, lowered in a container 9a and then raised in the interior of a leg part of a water column 3 at 10<-3> to 10<-4> m/sec speed. On the other hand, hydrochloric acid and hydrogen peroxide are fed from feed pipes 14 and 15 into a reactor evaporator-crystallizer 4 kept at 25-90 deg.C under 20-400mmHg pressure and reacted. The produced NaCl is then lowered from the bottom of the reactor evaporator-crystallizer 4 into the interior of the leg part 3 of the water column and brought into countercurrent contact with the rising NaCl/NaClO3 brine and washed. The resultant NaCl suspension is settled in the container 9a, subsequently transferred to a container 9b, intermittently fed to a filter 11b with a pump 10b and filtered to recirculate the filtrate to the container 9b or tank 1.

Title: Fluoroscopic imaging table
Inventor: HARA AKIO
IPC: A61B6/04
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To reduce space for setting up a fluoroscopic imaging table including its depth in order to load the stand sideways with an X-ray car or lengthwise so that other units can be loaded on the sides of the stand. SOLUTION: Rack 9 is provided with slide base 8 of the fluoroscopic imaging. Necessary space for setting up the stand can be smaller and the depth can be shorten by moving the stand on the rack 9 connected with setup movement with small gear wheel 14 in the longitudinal direction. Moving the stand in the longitudinal direction can reduce space for setup of the stand. By loading the stand with an X-ray car sideways, the body of the car can be shortened and other checkup appliances can be loaded. When the stand is loaded lengthwise, space efficiency is high by loading chest-photographing devices on the sides of the stand. Economic efficiency in hospitals is high because a medical checkup in a much smaller hospital room is possible, for space for setup of the stand is much smaller than that of current models.

Title: Method for gas pressure injection molding
Inventor: MATSUMOTO YUICHI
IPC: B29C45/26
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To simple conduct a gas pressure injection molding with an easily cleaning mold by press-fitting a pressurized gas between a molten resin in a cavity having an ejector pin and a back side cavity except a gap capable of passing a gas without introducing the resin between both the cavity surfaces of the front and back sides of a molding and a mold. SOLUTION: After a molten resin is filled in a cavity of a mold 1, a pressurized gas of inert gas such as a nitrogen or the like is press-fitted from a pressurized gas inlet 12 in a space 7, fed into a cavity via a gap retained between a movable mold 1b and an ejector pin 9 to press the resin in the cavity to a front side cavity surface 2. Since a heat insulator 3 is provided on the surface 2, the molten resin is not quickly cooled to maintain its fluidity near the surface 2 to press it to the insulator 3, thereby improving a mold reproducibility on the overall front side of a molding. Number of press-fitting holes of the pressurized gas is minimized to simplify the mold. Further, removal of the pin 9 is possible to facilitate its cleaning.

Title: Energy storage system and its using method
Inventor: MASUBUCHI HIDEO
IPC: H02J15/00
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To convert pneumatic pressure into electricity or to use the pneumatic pressure as power as is, or to use it as a cooler, making the best use of the characteristics of adiabatic expansion in the daytime by storing power as pneumatic pressure in place of electric power. SOLUTION: Using high-pressure steam or midnight electric power generated in a thermoelectric power plant at midnight, 100-1,000 atm of compressed air is produced, led with pipes to the inside of the sea where its pressure is the same with that of the compressed air to prevent a container from being broken due to pressure, and is stored in a comparatively simple container. The compressed air is extracted in daytime for power generation. Additionally, it is distributed as is with a thin pipe network to each place, without being converted into electricity, and used as power or as a cooler. Incidentally, a storage container is pressed with a weight which resists its buoyancy in a shallow sea.

Title: Electrical connector
Inventor: ODA KENZOU
IPC: H01R13/64
Filed: 1990-12-06
Abstract: PURPOSE:To obtain a small-sized and high performance connector by preventing a guide member from being disconnected from a female connector at the time of disconnecting a male connector, and ensuring the return of the guide member to an initial position after disconnecting the male connector. CONSTITUTION:When a male connector 10 is disconnected in the coupled state of male and female connectors 10 and 20, only the connector 10 first moves, and the rear slope 12b of the third projection 12 comes in contact with the end 40 of an elastic arm 36, thereby causing a member 30 to start a slide motion. When the connector 10 is further moved, the end 40 of the elastic arm 36 comes in contact with a projection 28. In this case, the end 40 of the elastic arm 36 is strongly coupled to the rear slope 12b of the projection 12 and, therefore, the elastic arm 36 slides, while being warped inward, and goes over the projection 28, thereby causing the member 30 to reach a temporary fixing position. Subsequently, when the connector 10 is pulled out, the end 40 of the elastic arm 36 comes in contact with a projection 26 and, therefore, the projection 12 goes over the aforesaid end 40. As a result, only the connector 10 is released from the connector 20.
