Abstract: The present invention reduces chattering of a sensor flag at a home position and alleviates a collision noise of the sensor flag with a simple configuration. A sheet detecting apparatus includes a turning portion, a sensor outputting a detection signal in response to turning of the turning portion to the detecting position, a first sliding contact portion sliding in contact with the protruded portion so as to move relatively to the protruded portion in an axial direction of the turning portion when the turning portion returns from the detecting position to the home position, and a second sliding contact portion sliding in contact with the protruded portion so as to move relatively to the protruded portion in the axial direction of the turning portion when the turning portion turns from the home position to the detecting position.

Abstract: The image fixing apparatus forms a cleaning nip portion by pressing a web roll-up portion on a fixing rotation member with a feeding roller, a used portion for cleaning of the web is fed from a cleaning nip portion formation area, and during non-cleaning, a roller is at a waiting position at which the roller is farther from the fixing rotation member than its position during cleaning so as to separate the web roll-up portion from the fixing rotation member. Accordingly, it is possible to reduce degradation of a cleaning ability due to a toner component held by the used portion of the cleaning web.

Abstract: In a system in which current is detected in an inexpensive manner or in a system in which a position detector is omitted, the present invention provides a high-efficiency vector controller for a permanent magnet motor that can minimize current at the same torque even when there is setting error (R−R*) in resistance. Even when a current value commanded for the d-axis is set to zero, a virtual inductance value calculated from a detected q-axis current value is used for output voltage value calculation and phase error estimation calculation; so even if there is setting error (R−R*) in resistance, current can be minimized at the same torque and thereby the present invention can provide a high-efficiency vector controller for a permanent magnet motor.
