Filed: 1981-01-09
Abstract: PURPOSE:To eliminate self-discharge and restrictions on battery composition materials in a metal-bromine secondary battery of an electrolyte circulating type by adding tertiary alkylamine and acid to a positive electrolyte composed of a  metal bromide aqueous solution. CONSTITUTION:Tertiary alkylamine and acid are added to a positive electrolyte composed of a metal bromide aqueous solustion so that the tertiary alkylamine is dissolved in the electrolyte. The electrolyte in a negative electrolyte storage tank 6 is circurated into a negative chamber 2 by a pump 9, and the electrolyte in a positive electrolyte storage tank 7 is circulated into a positive chamber for charging a battery. During this time, bromine deposited in the negative chamber 2 is either dissolved in the electrolyte, or is reacted with the tertiary alkylamine to generate bromine complex and is settled at the bottom of the tank 7, thus eliminating problems of self-discharge or corrosion. During discharging, the bromine complex and the electrolyte from a bypass 11 which does not include it are sent into the negative chamber 2 for discharge.

Title: Mixing device for hot water and cold water
Inventor: YONEKUBO HIROAKI
IPC: G05D23/13
Filed: 1991-01-11
Abstract: PURPOSE:To dispense wih the throttle hole of a mixing valve and to always perform hot water supply with stable temperature by performing such control that a flow rate is reduced within a range capable of securing a prescribed minimum flow rate by a control valve when no hot water temperature set by a temperature setter is obtained at the mixing valve. CONSTITUTION:When an instruction to supply large quantity of hot water is issued from a setter 36, the control valve 34 is opened widely once, and water quantity passing the heat exchanger 21 of a hot water supply heat source machine 20 is increased. When the water quantity exceeding the heating capacity of the heat source machine 20 flows, the temperature of supplied hot water is decreased, and the hot water side valve of the mixing valve 24 opens a hot water side passage 23, and a water side valve is driven to close a water side valve 25. Thereby, when no preset mixed hot water temperature is obtained in a state where the water quantity is throttled and a micro switch is operated and the supply quantity of cold water goes to zero, the control valve 34 throttles the mixed hot water quantity after the lapse of prescribed time. The minimum quantity to be throttled is decided by detecting the mixed hot water quantity by a flow rate sensor 35, and regulating the mixed hot water quantity by the control valve 34 up to the flow rate set in advance within a range where no oscillation of the mixing valve 24 occurs.

Title: Manufacture of semiconductor element
Inventor: TANETANI MOTOTAKA
IPC: H01L21/3065
Filed: 1989-01-10
Abstract: PURPOSE:To obtain a fully rapid etching rate without inducing damage to a semiconductor wafer by irradiating charged particles into the semiconductor wafer which is introduced into vacuum from air and then allowing a reaction gaseous substance to contact this irradiation region. CONSTITUTION:There are a large amount of oxygen or carbon atoms or an absorbate 102 due to molecule on the surface of a semiconductor substrate 101 introduced from air. If an electron beam is irradiated within a high vacuum such as an etching chamber, a semiconductor molecule on the surface of the semiconductor substrate is excited, thus enabling the absorbate and a bond 103 to be cut easily. Then, when a chlorine gas 120 is irradiated to the semiconductor substrate 101, normal reaction between the chlorine gas and GaAs advances on the surface of the semiconductor substrate at a region 150 where electron beam is irradiated. That is, the surface absorbate 102 functions as a mask with the thickness equal to that of an atom layer and etching advances only at the region 150 where an electron beam 110 is irradiated. Thus, there is no damage to the semiconductor substrate and a sufficient etching rate can be obtained.

Title: Vector control device of induction motor
Inventor: MORI MASATO
IPC: H02P21/22
Filed: 1994-01-14
Abstract: PURPOSE:To enhance a torque output in a constant-output control operation by a method wherein, when a rated torque current is made to flow, the limit value of an exciting shaft voltage is decided on the basis of a rotation angular frequency and a torque-shaft-current command value. CONSTITUTION:The following points are different form conventional cases. When an exciting-shaft-voltage limit value V1aLIMB is operated by a voltage- limit-value and exciting-current-command-value operation part 14, it is found from Formula I in such a way that only the voltage of an exciting shaft is not applied to a limiter when a torque-shaft-current command value is at a rated value (I1b*=Iibn) and the rotation angular frequency wr of a motor has become large up to a constant output range. In addition, a torque-shaft-voltage limit value V1bLIMB is found from Formula II. At this time, as an exciting-shaft- current command value, a lower value is used because a current which is at a value or higher in Formula III cannot be made to flow due to the value of the torque-shaft-voltage limit value. In Formulas, Lsigma represents an equivalent leakage inductance, V1LIM represents primary voltage maximum value for PWM control, V1aLIM represents an exciting-shaft-current limit value, and L1 represents a primary inductance.
