Title: Scroll type compressor
Inventor: KIKUCHI TOSHIYUKI
IPC: F04C18/02
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To restrict any drop of the volumetric efficiency of a scroll type compressor during its high speed rotation by forming a through hole which penetrates a spiral body in its radial direction near the end terminal of a spiral of at least either one spiral body of a movable scroll and a fixed scroll and installing, in this through hole, a check valve which opens only during a suction stroke. SOLUTION: In a scroll type compressor, a pair of pockets are partitioned between the spiral body of a movable scroll and the spiral body 16b of a fixed scroll 16 and these pockets move from the terminal end part to the starting end part of a spiral so as to compress fluid inside of pockets, in response to the revolution of the movable scroll around the fixed scroll 16. In this case, a through hole 40 for penetrating the spiral body 16b in the radial direction is formed near the spiral terminal end of the spiral body 16b and a check valve 50 which is opened only during a suction stroke is installed in this through hole 40. Accordingly, the sectional area of a communication passage for communicating the suction chamber with pockets is increased so as to suppress any increase in pressure loss during high speed rotation is suppressed.

Title: Rotor position detector for brushless motor
Inventor: NAKAYAMA TOMOHARU
IPC: H02P6/08
Filed: 1991-11-12
Abstract: PURPOSE:To suppress a transition phenomenon after end of detecting a rotor position to end of a 3-layer AC excitation and to reduce a variation in a rotor position by gradually decreasing a voltage or a current command until it becomes zero when an amplitude of a rotating angle of a rotor is sufficiently decreased. CONSTITUTION:The rotor position detector for a brushless motor comprises a setter 467 for setting a variation amount per unit time for gradually enhancing a frequency command, a switch 468 to be closed immediately after the rotor position is completely detected, and an integrator 469 for integrating the output from the setter 467. A 3-phase AC-excitation frequency command is gradually raised as a time is elapsed after the end of detection of the rotor position, and when the amplitude of the rotating angle of the rotor is sufficiently decreased, the 3-phase AC excitation is finished (voltage or current command is set to zero). Thus, transition phenomenon after the end of detecting the rotor position to the end of the 3-phase AC excitation is suppressed, thereby reducing a variation in the rotor position, and hence a detecting accuracy of the rotor position can be improved.
