摘要： A control apparatus and a semiconductor apparatus of AC motors capable of reducing torque ripple with a comparatively simple circuit corresponding to a high withstand voltage and capable of driving a motor at high efficiency even when the rotational speed or load has changed. The control apparatus detects first phase signals fixed in relative phase to induced voltages of the motor and current polarity signals, recognizes phase differences between them, generates second phase signals so as to make the phase differences approach zero to drive the motor at high efficiency, generates modulation wave signals having quasi-sinusoidal waveforms or trapezoidal waveforms on the basis of the second phase signals, compares the modulation wave signals with a carrier wave signal, and conducts PWM control on an inverter.

摘要： A surface light source device includes a light guide plate having a light outgoing plane in one principal plane thereof; and a light source facing one end face of the light guide plate. A plurality of deflection patterns are formed in a surface facing the light outgoing plane of the light guide plate, the deflection pattern including an inclined plane located on a light source side and a re-incident plane substantially perpendicular to the light outgoing plane. Light emitted by the light source into the light guide plate is reflected by the inclined plane and then the light is outputted from the light outgoing plane. A tilt angle (α) of the inclined plane satisfies: 45°−[arc sin(sin θ/n)]/2≦α≦45°+[arc sin(sin θ/n)]/2, wherein θ is an angle formed between a direction of the peak brightness of the light outputted from the light outgoing plane and a direction perpendicular to the light outgoing plane, and n is a refractive index of the light guide plate, and wherein θ is within the range 6-15 degrees.

摘要： A detachable-type vehicle sun shade apparatus is disclosed for use in vehicles having glass sun roofs installed between a center roof material and an exterior panel, both of which define an opening. The opening has a flange mounted trim strip therearound and a holder is mounted along a first edge of the opening. A sun shade has a first edge receivable between the holder and the trim strip. A stopper is rotatably mounted on the sun shade adjacent the second edge of the sun shade, with the stopper including edge engaging structure for engaging the trim strip along a second edge of the opening which is adjacent the second edge of the sun shade. A knob is provided for rotating the stopper and bringing the edge engaging structure into engagement with the trim strip along the second edge of the opening. The second edge of the sun shade is pressed against the trim strip along the second edge of the opening when the stopper is rotated to a position where the edge engaging structure engages the trim strip along the second edge of the opening.
