Title: Method and device for controlling charge of battery
Inventor: HONMA TOKUNORI
IPC: H02J7/10
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To charge a storage battery at high precision, so as to prevent overcharge, by controlling charging through a process of detecting that the change amount of the inner impedance per unit time in the charging last stage of the storage battery exceeds a specified value. SOLUTION: The inner impedance of a storage battery, the battery voltage, the battery temperature are changed around 140 minutes after charge is started, in particular, the inner impedance is suddenly changed. The change amount of the inner impedance per unit time is approximately half as large as the inner impedance in 140 minutes and larger than that of the battery voltage and the battery temperature. Therefore, control of charge by the detection of the change amount of the inner impedance per unit time is more reliable than that by the detection of the charge of the battery voltage and the battery temperature, the risk of overcharge is low, and charge can be controlled at high precision.  When the change amount of the inner impedance exceeds 2.0MΩ/min., that is detected, charging is stopped, and the charging electric amount is 95% of the discharging amount, and overcharge can be prevented.

IPC: C02F1/46
Filed: 1993-09-30
Abstract: PURPOSE:To prevent alkaline water and acidic water from being mixed mutually at the time of switching the polarity of electrodes by electrolyzing water remaining in an electrolytic bath by polarity switching voltage and restarting water supply either after the remaining acidic water in the electrolytic tank is converted into alkaline water or neutral water, or after the remaining alkaline water is converted into acidic water or neutral water. CONSTITUTION:Before polarity of electrodes is switched or simultaneously with polarity switching, an opening and closing valve 11-is closed for a prescribed period and in the condition that the water supply to the electrolytic tank 7 is stopped, the water remaining in the electrolytic tank 7 is electrolyzed by the electrolytic voltage after the polarity switching. Consequently, the remaining alkaline water of the electrolytic tank 7 produced before the polarity change is electrolyzed in a positive pole chamber after the polarity change and the water gradually changes to acidic side. In the same way, the remaining acidic water in the electrolytic tank 7 produced before the polarity change changes gradually to alkaline side. As a result, after the remaining acidic water changes to alkaline water or neutral water or after the remaining alkaline water changes to acidic water or neutral water, the opening or closing valve 11 is opened and while water being supplied to the electrolytic tank 7, electrolysis of polarity switching is continued.

Title: Production of single crystal
Inventor: KURAMOCHI KAORU
IPC: H01L21/208
Filed: 1988-10-25
Abstract: PURPOSE:To precisely control the amt. of Sb to be vaporized when a single crystal is pulled up and to uniformize the Sb concn. in the axial direction of the single crystal by adjusting the flow velocity of an inert gas to be blown against the melt surface and the melt area on which the inert gas is directly blown. CONSTITUTION:In the production of an Sb doped single crystal by the CZ method, a shielding member 9 is set above a crucible 2, and a control ring 10 is suspended below the member 9. When a single crystal 7 is grown, an inert gas such as Ar is supplied from the upper part to the region A surrounded with the control ring 10 on the melt surface in the crucible 2 at a specified flow velocity. The inert gas is mostly circulated along the melt surface in the region surrounded with the control ring 10, hence the amt. of the gas current is increased, the partial pressure of Sb is lowered, and the vaporization of Sb is accelerated. The area of the region A on which the inert gas is directly blown at a high flow velocity is changed by changing the diameter of the control ring 10, and the amt. of Sb to be vaporized is precisely controlled in combination with the flow velocity of the inert gas.

Patent JP-H0221161-A (JP)
Title: Heating apparatus
Inventor: OKUNO MASAHARU
IPC: F24H7/04
Filed: 1988-10-27
Abstract: PURPOSE:To reduce thermal shock on a rotary part and pressure loss in a heat exchanger, and also to make a heating apparatus compact by cooling a heat exchange drum by air from an air fan, and by supplying air to a room after high temperature air from a combustion part and air heat-exchanged with the rotary part are diluted. CONSTITUTION:As a rotary part 30 revolves continuously, a heated position of the rotary part 30 on the combustion part 10 side moves towards the air blowing part 40. A heated portion of the rotary part 30 that moves to the air blowing part 40 side is heat-exchanged with air that is forcibly sent to the air blowing part 40, so that air is heated and the rotary part is cooled down. Air heat-exchanged with the rotary part 30 reaches an outlet 41 and is diluted with air from an air fan 52 to cool down suitable for supplying to a room. Therefore, even if air discharged from the outlet 41 is rather high temperature, air blowing into the room can be kept at an adequate temperature so that air flow required for heat exchanging can be reduced and pressure loss is low. As the air from air fan 52 is firstly blown to the heat exchange part, the combustion part 10 can be cooled and abnormal heating can be prevented.

Abstract: PURPOSE:To provide a stable combustion by a method wherein each of a thin flame burner and a thick flame burner is provided with an opening hole, a passage is arranged between a case and a burner end and thick gas is leaked. CONSTITUTION:Lean mixture gas generated at a thin mixture gas chamber 6 at a central part during combustion is flowed from an opening hole of a thin flame burner 3 so as to form a thin flame on a thin flame side flame hole. Thick mixture gas generated at thick mixture chambers 7 at both ends flows from the opening hole of the thick flame burner 4 so as to form the thick flame on the thick flame so as to hold alternative adjoining thin flames from each other. In addition, the thick mixture gas within the thick mixture gas chamber 7 is flowed into a passage 17 between the ends of the burners 3, 4 and a case 2 so as to form the thick flame on the upper part of the passage 17 with the leaked thick gas. With such an arrangement as above, since flame is formed in such a way that the thick flame encloses the thin flame, a thin flame holding becomes superior and then the combustion can be stabilized.
