Title: Transporting method for used ion exchange resin
Inventor: NATSUI KAZUJI
IPC: C02F1/42
Filed: 1988-07-22
Abstract: PURPOSE:To reduce an amt. of radioactive liquid waste product by discharging both of used ion exchange resin and transporting water for the ion exchange resin from an ion exchange tower into a tank, separating the used ion exchange resin from the water in the tank, and injecting the separated transporting water into the ion exchange tower again. CONSTITUTION:An ion exchange resin tower is drained by opening a vent valve 4 and a drain valve 5 after closing an inlet valve 2a and an outlet valve 3a of treating water for the ion exchange tower 1. The drain is stored in a tank 12 after passing through a temporary pipe 19. After closing valve 4, 5, a discharge value for waste resin 7a is opened. Then, a backwashing water valve 8 and an inlet valve 9a for compressed air are opened. Thus, the ion exchange resin on an ion exchange resin bed 6 held on a screen 10 is loosened by the backwashing water pressurized by a pump 13 and fluidized. The whole part of the ion exchange resin bed 6 is pushed from above by the pressurized air supplied from a valve 9a and the resin is collected in a vessel 11 in the form of a slurry through a valve 7a. On one hand, transporting water for the resin is stored in a tank 12 through a mesh 16 and reused by a pump 13.

Title: Modulation system for information signal
Inventor: SHIBATA ISAMU
IPC: G06K15/12
Filed: 1986-08-01
Abstract: PURPOSE:To correct the distortion of a recording image by correcting variation in the diameter of a laser beam in response to main scanning position using a correcting means and varying the duty ratio of an information signal to vary its exposure time. CONSTITUTION:A trapezoid wave (triangular wave) shaping circuit 18 shapes the information signal from a shift register 16 into a trapezoid wave signal, which is compared by a comparator 19 with the output signal of a D/A converter 15 and converted into a binary signal. The information signal form the comparator 19 varies in duty ratio according to the scanning position and a modulating means modulates the output beam 1 of a laser with the signal. The high level of the information signal is black and a photosensitive body 4 is irradiated by the laser beam 1. Then when the diameter of the laser beam 1 is large, the radiation time of the beam 1, i.e. exposure time of the photosensitive body 4 becomes short and when the diameter of the beam 1 is small, the radiation time of the beam 1 becomes long. Consequently, the distortion of the recording image depending upon the diameter of the beam 1 is corrected.

Title: Production of light guide sheet
Inventor: SHIOZAWA ETSUO
IPC: B32B17/04
Filed: 1980-12-22
Abstract: PURPOSE:To produce a light guide sheet in a short time and with cheap labor, by setting down an optical fiber into a space formed between two sheets of wall members to arrange in parallel a number of optical fibers into the space and then injecting an adhesive from above the optical fibers. CONSTITUTION:A pile-up device 1 is formed with two sheets of wall member 2 set in parallel to each other with a 640mum space secured between the inner surfaces 5 plus two sheets of side plate 3. A number of optical fibers 15 of 400mum outer diameter are put en bloc on an oblique surface 4 of the member 2. Thereafter, the air within a space 6 is absorbed by a vacuum pump 14, and thus the optical fibers 15 are put down into the space 6. After all fibers 15 are set into the space 6, an adhesive made of resin having a low refractive index is injected into the space 6 from above. Thus the fibers 15 are stuck to each other.

IPC: G10H1/18
Filed: 1993-06-28
Abstract: PURPOSE:To provide a sound source capable of directly and precisely judging the time releasing a channel regardless of a kind of a storage waveform read out from a waveform memory. CONSTITUTION:The storage waveform consisting of only an attack part is read out from the waveform memory, and when an address of a loop part is read out, since no loop part exists at the time, an end signal ENDS becomes a high level by an end detection circuit 35, and on the other hand, the output becomes the high level also by a loop '0' code detection circuit 43. The AND of the two outputs are taken by an AND circuit 42, and the signal NLEND with the high level is outputted from the AND circuit 42. When the high level signal NLEND is detected by an envelope generator, by the envelope generator, the envelope of the channel where the end signal ENDS is detected is dumped, and the channel is released, and next musical sound information is allocated.

Title: Failure diagnostic apparatus for evaporated fuel purging system
Inventor: ITOU TOKIJI
IPC: F02M25/08
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To diagnose quickly and accurately the existence or nonexistence of abnormality of closed sticking in a purge control valve. SOLUTION: This failure diagnostic apparatus for an evaporated fuel purging system is constituted of an electronic control unit(ECU). A purge control valve is disposed in an evaporation passage including a fuel tank. Depending on engine operating states, the ECU calculates an accumulated value ΣPR of purge flow rates when purging evaporated fuel generated in a fuel tank into a intake passage based on opening of the purge control valve.  The existence or nonexistence of abnormality of closed sticking in the purge control valve is determined by timing, which is defined by AND of a base where the calculated ccumulative value ΣPR of purge flow rates reaches a predetermined value α, and a case where a time for introducing intake negative pressure Pth in the evaporation passage reaches a predetermined time β when introduction of a predetermined intake negative pressure Pth is estimated to be completed. A predetermined time β is set as a time corresponding to a time where an ccumulative value of mean values of the purge flow rates reaches a predetermined value α.

Abstract: PROBLEM TO BE SOLVED: To prevent the bedewing in a blower and the corrosion of blade in the blower by cooling the outer air at the exhaust side of the blower to a suitable temp. with a cooling tower and dehumidifying moisture contained in the outer air. SOLUTION: A heat radiating device 3 is connected with the exhaust side of a blower 1 and a cooling tower 2 for cooling the outer air is connected with the upper side of this heat radiating device 3.

Abstract: PURPOSE: To form a high-quality transparent plastic product for the production of optical materials, by lowering a volume shrinkage during curing by carrying out preliminary crosslinking by using an α-methylstyrene dimer as a chain transfer agent and, then, casting and curing the produced prepolymer.  
     CONSTITUTION: Up to 2wt% α-methylstyrene dimer (2,4,-diphenyl-4-methyl-1- pentene) is added to a multi-component monomer mixture consisting of a monomer which, when polymerized, alone, forms a linear polymer, e.g., methyl methacrylate and a crosslinkable polyfunctional monomer, e.g., diallyl terephthalate. The resulting mixture is prepolymerized (during this, the volume shrinkage of the system is substantially complete). The produced precrosslinked polymer is poured into a desired mold, in which the polymer is completely polymerized and cured to form a transparent plastic having a visible light transmissivity of at least 70%.
