Title: Regenerative brake system for vehicle
Inventor: TASHIRO HIROSHI
IPC: B60L50/15
Filed: 1994-12-22
Abstract: PURPOSE: To avoid abnormal drop of battery capacity due to regenerative brake operation after finishing the charging operation of a battery. CONSTITUTION: Power generating operation of a generator/motor is interrupted (Step 313) during the pause interval, i.e., up to a moment of time when the amount C of discharged current accumulated by an accumulation means immediately after ending the regenerative brake operation (Step 306) is substantially equalized to the accumulated amount of charging being fed to the accumulation means during the regenerative brake operation (Step 310). Since the current can be discharged (consumed) accurately by an amount corresponding to the regenerated amount of current (capacity), abnormal drop of the capacity of accumulation means can be prevented even if a high current is discharged immediately after ending the regenerative brake operation although an overvoltage is generated temporarily.

Title: Video agc circuit
Inventor: KAKIZAKI HIDEHIRO
IPC: H03G3/20
Filed: 1988-12-20
Abstract: PURPOSE:To realize an accurate AGC operation by composing a video AGC circuit of a detecting means to detect the level of a horizontal synchronizing signal in a composite signal and an AGC amplifier in which gain is controlled based on a signal obtained in the detecting means. CONSTITUTION:In one sample-and-hold circuit 11, the pedestal level of a signal (a), from which a color burst is removed, is held by a pulse (d), and in the other sample-and-hold circuit 10, the peak level of the synchronizing signal of the signal (a) is held by a pulse (c). Further, since both the levels are difference-amplified in a differential amplifier 12, a signal to indicate the level of the horizontal synchronizing signal appears at the output side of the differential amplifier 12. The fluctuation amount of the signal is suppressed in an integration circuit 13, adjusted in a variable resistance 14, made into AGC voltage, and inputted to an AGC amplifier 3 as a gain adjusting signal. Thus, a video signal to appear at an output terminal 2 is changed only by the level of the horizontal synchronizing signal, and the level is never changed by the content of video.

Title: Producing method of activated carbon molding
Inventor: DEMURA KATSUNOBU
IPC: C01B31/08
Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a producing method of an activated carbon molding which is produced by combining activated carbon granules having shapes such as particles, small pieces with binder and solidifying the same without damaging a function of the activated carbon. SOLUTION: The activated carbon granules having shapes such as particles, small pieces are combined and solidified by using a re-emulsification type powdery resin and a foaming agent, and thereby the activated carbon molding is produced. That is, a powdery mixture is prepared by compounding the activated carbon granules and the re-emulsification type powdery resin, and air bubbles are generated by adding the foaming agent into water and kneading the mixture. Subsequently, an activated carbon composition, which is obtained by mixing the powdery mixture and the air bubbles, is molded, then the activated carbon molding is produced by evaporating moisture in the dry state.  As the moisture is included in an air bubble film generated by the foaming agent, the re-emulsification type powdery resin is brought into contact with the air bubbles, thereby, only the surface layer part of the resin granules comes to an emulsified state and is combined with the activated carbon. In such a manner, the re-emulsification type powdery resin is not emulsified up to the emulsion state, therefore, narrow pores of the activated carbon are not blocked, the activated carbon granules are combined and the molding can be produced in the state of keeping the function of the activated carbon.

Abstract: PURPOSE:To shorten the open-close cycle to increase the heat conveying capacity of a heat conveying device where a refrigerant is heated with the aim of heating, by arranging plates with perforations close to the interior wall of a liquid receiver at nearly equal intervals. CONSTITUTION:A gas-liquid separator 1 is situated above a refrigerant heater 2 and communicates with the refrigerant heater 2 via an inlet pipe 3 and an outlet pipe 4. A heat conveying device 18 has a liquid receiver 5 that is situated above the gas-liquid separator 1 and communicates with the gas-liquid separator 1 through an on-off valve 8 and a first check valve 6. A circulation path 19 connects the gas-liquid separator 1, a radiator 10 and the liquid receiver 5. A connecting pipe 20 connects a second check valve 12 and the liquid receiver 5 and is on the tilt against the center of the liquid receiver 5. An supercooled refrigerant is spirally sprayed into the liquid receiver 5 and mixes up with a high-temperature gas refrigerant quickly. Therefore, the refrigerant pressure inside the liquid receiver 5 drops sharply as the gas inside is condensed by the atomized supercooled refrigerant, so that the liquid refrigerant is sucked fast into the liquid receiver 5 at once when the on-off valve 8 is opened.
