Title: Dispersion strengthened hypereutectic aluminum silicon alloy
Inventor: TOKUI MASAAKI
IPC: C22C1/10
Filed: 1983-05-13
Abstract: PURPOSE:To obtain an alloy having high wear resistance and strength by dispersing fine particles for strengthening to be dispersed in Al matrix into primary crystal Si as well and specifying the size of the primary crystal Si as well as the grain size, intergranular distance and volume ratio of said fine particles. CONSTITUTION:The size of primary crystal Si is more preferable as said size is smaller and is made <=20mu. Fine particles for strengthening are the oxide, carbide, nitride, etc. of Si, etc. which exist stably in Al matrix at a high temp. without growing to or forming coarse grains and the grain size thereof is made <=0.5mu in order to obtain substantial dispersion strengthening. The intergranular distance of the fine particles is more preferable as said distance is smaller and is made about <=30mu. The larger the amt. of the fine particles, the better, but if the amt. exceeds 20% by volume, substantial dispersion strengthening cannot be expected and mixed dispersion is difficult and therefore 20% is the upper limit. The fine particles for strengthening are uniformly dispersed in a molten hypereutectic Al-Si alloy in order to satisfy the above-mentioned conditions and thereafter the molten alloy is quickly cooled and is pressurized, by which the intended alloy is obtd.

Title: Protecting system for parallel operation of inverter
Inventor: NOZAKI TOSHINOBU
IPC: H02J3/38
Filed: 1979-07-03
Abstract: PURPOSE:To protect the inveter by separating it from parallel operation when a detector sensing an inverter's abnormal operation and a sensor which works simultaneously with the indication of output current's unbalanced volume beyond the prescribed value, concurrently work. CONSTITUTION:The inverters 1, 2 converts AC current 3 to DC current by means of a power rectifier 11 and supplies AC current to a load 4 through a inverter 12. The output of an unbalance detector 5 provided between the inverters 1, 2 is applied to a level detector 18. At the same time, the inverter 12's abnormality is sensed by means of a pulse-width abnormality detector 17. These outputs are input to an AND circuit 19 and then to an interrupter 14 which separates the inveters 1, 2 from parallel-operation. Consequently, it is possible to separate the faulty inverter from parallel-operation when the detectors and 17 concurrently work, thus eliminating erroneous operation and continuing steady power supply to the load.

Abstract: PROBLEM TO BE SOLVED: To effectively reduce a noise radiated ahead of a vehicle from an engine room while ensuring ventilation of the engine room. SOLUTION: A sound insulating front grille panel 1 is provided with two sheets of plate material parts 11, 12 having many through-holes 10, cylinder member 13 directly connecting a half number of the through-holes 10, and an air chamber 14 connecting the rest of half number of the through-holes 10. A resonance frequency of the air chamber 14 is lower than 1 kHz, a component exceeding the resonance frequency of noises permeating the air chamber 14 generates a reverse phase, to offset a component of approx. 1 kHz of noise passing through the cylinder member 13. Consequently, a main component of noise with the central frequency of approx. 1 kHz leaking out to the forward from an engine room which is sound-proved by a sound absorbing material or the like, can be reduced while holding ventilation to the engine room.  A resonator opened to the engine room is arranged in a recessed part in a reverse side of a bumper, and similarly noise of approx. 1 kHz can be reduced.

Title: Metal recovery method from plating solution residue
Inventor: FUJITA SHIGERU
IPC: C22B7/00
Filed: 1978-07-14
Abstract: PURPOSE: To effectively recover copper by adding a flocculant to the copper pyrophosphate plating solution residues containing a large amount of active carbon and filtering and separating the flocculated active carbon from the plating solution residues then electrolyzing the same.  
     CONSTITUTION: Active carbon is charged into a copper pyrophosphate plating solution to let the impurities contained in this plating solution be adsorbed on the active carbon, whereby the copper pyrophosphate plating solution is refined. A flocculant is added to the plating solution residues containing a large amount of the adsorbent remained after recovery of this refined plating solution to let the adsorbent flocculate. Next, the flocculated adsorbent is filtered away from the plating solution residues, after which copper is recovered through electrolysis. This method provides an extremely high recovery efficiency of copper and saves labor for sludge treatment because of less sludge amount.

IPC: B65H31/34
Filed: 1989-04-04
Abstract: PURPOSE:To certainly perform matching treatment without damaging a sheet by a method wherein staple part is matched in the longitudinal and lateral directions by reciprocally moving a matching member by a stepping motor and imparting such a characteristic that torque is lowered as drive frequency becomes high to the stepping motor. CONSTITUTION:Sheets are sent in a staple tray 201 by drive rollers 68, 69 to fall freely therein and received in such a state that the lower ends of the sheets are brought to the contact state with a stopper 202. Herein, the matching part 205b of a matching plate 205 advances into the upper part of the tray 201 and falls in the direction shown by an arrow (b) to arrange a sheet bundle P in an up-and-down direction by said matching part 205b and the stopper 202. Further, a matching plate 204 moves in the direction shown by an arrow (a) and the sheet bundle P is arranged in a lateral direction by the matching part 204b of said plate 204 and a reference plate 203. The matching plates 204, 205 are respectively driven by a stepping motor. In this case, the stepping motor is driven with high torque until the matching parts 204b, 205b reach matching reference positions Pa, Pb and driven with low torque thereafter. By this method, out-of-phase is easily generated in the stepping motor to prevent the damage of a sheet.

Title: Regeneration of ion-exchange resin
Inventor: FURUNO NOBUO
IPC: B01J49/00
Filed: 1983-05-16
Abstract: PURPOSE:To regenerate ion-exchange resin while remarkably reducing the amounts of a chemical agent for regeneration and washing water to be used and the number of steps, by treating cation- and anion-exchange resins each under a separate condition with a conc. acid or base, and then washing them under the separate condition with water in a DC electric field. CONSTITUTION:Heavy cation-exchange resin K and light anion-exchange resin A are separated from each other by the difference in specific gravity at first and separately charged in cylindrical vessels 5. For the regeneration of the resin K, the resin K together with the vessel 5 is immersed in 2N-NaOH water at first and then placed inside a reaction tank 2' to which city water is supplied 14. Then, an underwater pump 10 is driven to circulate the city water between the tanks 2' and 2. Thereafter, new city water is injected 14 to perform the same treatment. After this operation is repeated several times, DC voltage is impressed between power sources 8-1 and 8-2 to bring out regenerating reaction. Hence, said reaction reaches equilibrium in a very short time. Since most of the resin K has been already regenerated, the resin K can be extremely preferably washed with water without deactivating it regardless of the presence of NaCl as a contaminant by removing remaining NaOH as a regenerating chemical agent therefrom.
