Abstract: PURPOSE:To efficiently treat waste water with the small amounts of hydrogen peroxide and a ferrous salt to be added, by oxidatively treating said waste water containing organic substance, adjusting its pH to precipitate flocks, and circulatively mixing a part of treated water after being subjected to solid-liquid separation in the waste water. CONSTITUTION:Treated water 3 circulated from a solid-liquid separation tank 2 is mixed in waste water 1 containing organic substance, and the resulting liquid mixture is supplied to a reaction tank 4. Hydrogen peroxide 5, a ferrous salt 6 such as ferrous sulfate and optionally a pH adjusting agent 7 are charged in the reaction tank 4 to adjust a pH to about 2-4, and the liquid mixture is agitated therein for a predetermined time to oxidatively decompose dissolved organic substance. After the oxidative reaction is finished, the oxidatively treated water 8 is sent to a coagulation tank 9, wherein pH is adjusted to about 5-8 by the addition of an alkali agent 10 to precipitately coagulate flocks based on ferric hydroxide. Thereafter, the liquid mixture is separated into treated water 3 and sludge 11 in the precipitation tank 2, and a part of said treated water 3 is circulated to raw waste water.

Title: Device for metal hydrogenation reaction
Inventor: SHICHIRI MASATAKA
IPC: C01B6/00
Filed: 1982-03-09
Abstract: PURPOSE:To carry out quickly a metal hydrogenation reaction and to improve heat conduction, by closing each container with a porous filter cover, equipping the titled device with fins of a substance having high thermal conductivity, providing hydrogen flow channels divided by the fins. CONSTITUTION:When a hydrogen gas is fed to the hydrogen flow pipe 2, part of it is passed through the major flow channels 13a-13d in the main body 11 of a container and combined with alloy powder (e.g., LaNi5, etc.). Another part of it is passed through the by-pass channel 13e, made to flow to the downstream side, partially penetrated to the interior of the major flow channels in the main body of a container and partially passed through the by-pass flow channel to the downstream side further. When the alloy powder is combined with the hydrogen gas, heat is generated, and this reaction heat is quickly transferred from the outside of the hydrogen flow pipe 2 to a heating medium. When the temperature of the heating medium from the outer periphery of the hydrogen flow pipe 2 is raised to >= the reaction equilibrium temperature of both the substances, decomposition is started, hydrogen is released and heat is abosorbed. Since each container is closed with the porous filter cover 12, the reaction powder substance is not placed under a hermetic compressed condition, and the furnishing of the by-pass channel 13e improves hydrogen flow and promotes the reaction.

Title: Ink ribbon cassette
Inventor: KANEKO AKINARI
IPC: B41J32/00
Filed: 1985-02-27
Abstract: PURPOSE:To enable to release a tension having been exerted and to exert a tension on a core with a roll diameter made to be smaller than that on the other core, by providing a leaf spring so deformed as to change the pressure- applying direction thereof in accordance with the roll diameter of an ink ribbon being taken up. CONSTITUTION:With the progress of printing, the ink ribbon 20 is gradually transferred from a payout core 22 to a take-up core 23, and the roller diameter on the take-up core 23 is gradually increased, resulting in that an intermediate part 33 of the spring 33 is pushed and deformed to the payout core 22 side. When an 'excess quantity' beyond a balance point exceeds a preset quantity, the intermediate part 33 of the spring 30 is deformed in an arch shape to the side of the payout core 22. Thus, the spring 30 exertes a fixed tension on the core with a smaller roll diameter, and when the roll diameter is increased to or beyond a certain extent, the spring releases the tension having been exerted and exerts the tension on the core with a roll diameter made to be smaller than that on the other core.

Abstract: PURPOSE:To hear voice from a living body expressly even when a top plate with the living body placed thereon is moved within a photographing mouth, by selecting electric signal sent to a speaker from a microphone in accordance with the position of top plate, and thereby preventing voices from a plurality of microphones from interfering one another. CONSTITUTION:A living body P is placed on a top plate 13 of this medical diagnostic device 10 and is located within a photographing mouth 12b, and the top plate 13 is moved to perform photographing of different parts of the living body P. Meantime, eventually generated voice from the living body P is given through microphones M10, M20, M30, converted into electric signal, and fed to a selection means 21. When the top plate 13 moves to specified motion positions T10, T20, a photo-sensing means 20 senses the position, and a select signal generating means 11 sends a select signal S5 to the selection means 21 on the basis of location information of the top plate 13. The selection means 21 sends to a speaker S10 the electric signal selected on the basis of select signal S5, and the electric signal is converted into sounds and reproduced. Thus, voices from living body P can be heard expressly even though the top plate 13 with the living body P placed thereon is moved within the photographing mouth 12b.

Filed: 1987-02-20
Abstract: PURPOSE:To make a duty ratio at most double and to make it unnecessary to use a photoelectric converter of wide band by forming one frame of start bits with binary logic and inverse binary logic every bit unit in an information part. CONSTITUTION:A titled device has a circuit 10 which generates the binary logic signal and the inverse binary logic signal obtained by logically inverting the binary logic signal in pulse wave shape for the respective bits of a start mark signal and the information which should be transmitted, a circuit 4 which generates more than one bit of completion mark signal(stop bit) and an error detection circuit 12 which decides the error of transmission when the inverse binary logic signal is not added to the respective bits, in case of discriminating from the pulse shape waveform of a received signal every bit unit. Thus, positive logic signals and negative logic signals line each other in one frame of signals except a stop bit, so that the transmission band becomes at most a half frequency. Therefore, the reception circuit of wide band is not needed and at the same time the error check of transmission can be possible.

Title: Manufacture of lead frame
Inventor: TOGAMI TOKUMI
IPC: H01L23/50
Filed: 1990-02-20
Abstract: PURPOSE:To avoid defective bonding by a method wherein, after the tip parts of inner leads are plated, the tip parts are subjected to a coining process by a punch whose surface is roughed. CONSTITUTION:The tip parts 2a of the inner leads 2 of a lead frame 7 are subjected to a coining process by the punch 9 of a press. The surface 9a of the punch 9 which faces the lead frame 7 is processed so as to have a rough surface. Therefore, if the punch 9 is made to descend while the lead frame 7 is placed on a punching die 8, the lead frame 7 is subjected to a coining process. At that time, even if a coining process is applied after plating, the rough surface of the punch 9 prevents the tip parts 2a of the inner leads 2 from having mirror surfaces. With this constitution, defective bonding can be avoided.
