Title: Induction motor controller for vehicle
Inventor: ASABA SADAO
IPC: B60L9/16
Filed: 1990-03-27
Abstract: PURPOSE:To achieve smooth transition to slip frequency control by controlling an inverter such that the quotient obtained by dividing the terminal voltage of an induction motor, which is subjected to slip frequency control based on the output from the inverter, by the product of current and frequency will be constant. CONSTITUTION:When the vehicle speed is lower than a predetermined level, normal close contacts 32b1, 32b2 close to provide an output from a control amplifier 6 and a value, obtained by converting 13 a DC voltage ECF, to a divider 12 and the modulation factor gamma of an inverter 2 is set thus performing terminal voltage control. Upon detection of a vehicle speed higher than a predetermined value, contacts 32a1-32b2 are inverted and the output from the amplifier 6 controls the slip frequency FS which has been kept constant. A ratio between a command current IP and a set current Io is then generated 31 and multiplied by an output from a V/F setter 17, an inverter frequency F and a corrected 23 frequency to produce a required voltage ERQ which is then fed to the divider 12 in order to perform slip frequency control. Consequently, transition takes place smoothly from voltage control to slip frequency control. The invention is suitably employed in an electric rolling stock.

Filed: 1981-05-21
Abstract: PURPOSE:To manufacture an impeller, light, economical and having a high performance, by forming a blade having a required shape by way of bulging by expanding a prefabricated bag-like plate from the inside thereof by use of a pressurizing medium. CONSTITUTION:The inner space of a prefabricated bag-like plate 7 is pressurized beforehand (for instance, to 4-5atm) by injecting nitrogen gas into the inner space of the plate 7 from a gas injection port 10, so that the bag-like plate 7 can be protected against buckling when it is fixed between an upper and a lower molds 5 and 6. When the upper mold 5 is lowered to a required position by means of a press head (not shown) while heating the bag-like plate 7 by supplying current to embedded heaters 11, the upper mold 5 is lowered together with an upper and a lower retainers 8, 9 to a position where it is held in abutment with the lower mold 6. In this state, a bulging pressure (for instance, 40atm) is imparted to the inner space of the bag-like plate 7 by raising the pressure of nitrogen gas so as to shape the surfaces of the bag-like plate 7 into the configuration of molding surfaces 5a, 6a of the upper and the lower molds 5, 6. By thus completing the bulging operation, it is enabled to manufacture an impeller, light, economical and having a high performance.

Abstract: PURPOSE:To achieve efficient defrosting of an outdoor heat exchanger by passing through an auxiliary heating channel the engine-cooling water when it has reached a prescribed temperature. CONSTITUTION:When a air-conditioner is in cooling operation, the CPU 31 determines whether or not the outside air temperature Ta exceeds 15 deg.C by means of an outside air temperature sensor 32; when the temperature is determined at Ta>15 deg.C, the CPU 31 turns off a solenoid valve for cooling water 5 and turns on a solenoid valve for cooling water 4; when the temperature is found to be Ta<=15 deg.C, the solenoid valve 5 is turned on and the solenoid valve 4 is turned off. On the other hand, when the defroster is on, the cooling water for the engine 7 is circulated through a bypass 26 while the cooling water temperature Te is below a prescribed value (95 deg.C) and passed through an auxiliary heating channel 23 when the temperature Te has exceeded the prescribed value. Thus the defrosting takes place when the cooling water is under heated condition, so that the outdoor heat exchanger 2 can be defrosted completely.
