    Abstract: A resolver use angle detection IC subjected to a phase lock operation so as to follow not an angle θ(t) for detection, but a phase angle ωot±θ(t) having an offset of a frequency ωot in the phase lock units. For this reason, when the excitation frequency ωot is set sufficiently high with respect to the frequency of the angle θ(t), the phase angle ωot±θ to be followed in the phase lock units will not become zero. For this reason, an angle having a high precision can be found in real time regardless of the configuration not including the conventional apparatus in which the configuration is complex and the power consumption is large like a bipolar VCO and an up/down type counter.

    Abstract: A disk brake wherein the engagement portions of a return spring are prevented from coming out of respective retaining holes formed in the backing plates of friction pads, and at the same time the spring function portion of the return spring is prevented from interfering with the disk. After the caliper has been mounted on the carrier, the return spring is supported at three portions at each end thereof. The spring function portion is contacted by the protuberance, while the proximal end of each engagement portion is contacted by the entrance portion of the associated retaining hole. Further, the distal end of the engagement portion is contacted by the innermost portion of the retaining hole. In addition, the spring function portion of the return spring is bent radially outward of the disk along a recess formed on the inner side of the caliper.

    Abstract: A modulation circuit capable of high resolution pulse width modulation while keeping down the bit length and an image display provided with the modulation circuit. By the A/D converter 4, the video signal Sv converted into a binary code having a preset bit length is divided into a plurality of binary codes by the controller 3 from the most significant bit to the least significant bit. Corresponding to the thus obtained plurality of divided binary codes, serial data is generated for producing a pulse current of a pulse width and current value according to the value of the binary code and is output to pulse width modulation circuits 1 cascade connected to the controller 3. The pulse width modulation circuits supply LEDs 3 of the pixels pulse currents of pulse widths and current values corresponding to the serial data.
