Abstract: PURPOSE: To reduce the power consumption of a brushless motor by minimizing a 90 deg. phase-lead current to the amount required for driving the motor by monitoring the following-up state of the armature current corresponding to a target current calculated on a torque command value and successively increasing or decreasing the current. CONSTITUTION: A torque calculating section 24 calculates a torque current id sinθ to be made to flow synchronously to the electrical angle θ of a motor 2 on the basis of a torque command value calculated from a speed command and the detecting value of the electrical angle θ. On the other hand, an iq calculating section 30 and phase current converting section 28 calculate the 90 deg. phase- lead current iq sin(θ+90) to be supplied against the electrical angle θ. A current control circuit 40 controls the armature current of the motor 2 depending on the target current io obtained by synthesizing the d-axis current component and q-axis current component of the currents.  The iq calculating section 30 sets the 90 deg. phase-lead current iq by successively increasing or decreasing the current iq in accordance with the following-up state of the armature current to the target current io by using the maximum required torque which is set on the torque command Tcom as the upper limit value.

Title: Compressor valve structure
Inventor: SATOU MICHIO
IPC: F16K15/14
Filed: 1980-09-22
Abstract: PURPOSE: To prevent the cavitation erosion on the valve contacting face due to the refrigerant gas dissolved in the oil drip, by performing the surface hardening work through the laser on the surface where the suction valve and the delivery valve will touch the valve seat and the valve stopper.  
     CONSTITUTION: A suction valve 15 will collide with a valve seat 20 and a groove 16 during the suction and the compression strokes while a delivery valve 17 will collide with a valve seat 20 and a valve stopper 19 during the exhaust and the suction strokes. When an oil drip dissolving the refrigerant gas is stored in the pit produced on the surface of the valve seat 20, groove 16 and the valve stopper 19, the shock energy produced when compressing and destroying it is transmitted to the suction valve 15 and the delivery valve 17. But since the surface at the touching section of the valve is hardened by the laser, the production of the pit is suppressed to prevent the cavitation errosion of the valve.

Here the state in which PMV=0 means the state of thermal balance in human body and more than 95% of people feel pleasant. Further, a display judgement section 13 compares the output of the PMV calculation section 12 with a specified threshold value. Furthermore, a PMV display section 15 outputs display according to the output of the display judgement section 13. With this arrangement the proper and neutral state in which neither coldness nor hotness is felt is exactly recognized.
