IPC: H01M2/12
Filed: 1983-06-24
Abstract: PURPOSE:To prevent any leakage of electrolyte outside a sealed alkaline storage battery by placing an insulator having a network in the space formed between the gas inlet of a safety valve and a plate group. CONSTITUTION:A polypropylene insulator 7 of 1mm. thickness having a mesh of 2X2mm. is placed in the space formed between a plate group 2 and a safety valve body which has an elastic valve 6, a gas exhaust hole 5 and a gas inlet 1.

Title: Control method for alternating current motor
Inventor: SAKAI KEIJIRO
IPC: H02P27/08
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure primary resistance with accuracy and exercise accurate vector control by performing direct current excitation from the vicinity of a stopping frequency for a time with the inertial moment of a load and the secondary time constant of a motor taken into account each time the motor is decelerated or stopped. SOLUTION: When an alternating current induction motor 5 is decelerated or stopped, voltage is applied by means of an inverter 4 from a point of time at which a speed command or inverter frequency reaches the vicinity of a stopping frequency so that a constant direct current is passed through the motor winding for a desired time. By this direct current process, breaking torque is produced in the alternating current induction motor 5. Further, based on the ratio of the voltage applied to the alternating current induction motor 5 to the current passed, the primary resistance of the alternating current induction motor 5 is measured and vector control is exercised based on motor constants including the measured primary resistance.  Since as the result of this, the most suitable time can be measured according to applications involving a wide variety of loads, versatility is attained and further accurate vector control is accomplished even if motor temperature varies.
