    摘要: A position detecting device for a motor includes a resolver, amplifiers and a microcomputer. The microcomputer corrects an amplified sine wave signal to have the same amplitude in both positive and negative polarities, and corrects an amplified cosine wave signal to have the same amplitude in both positive and negative polarities. The microcomputer further corrects the corrected sine wave signal or the corrected cosine wave signal to have the same amplitude therebetween. The rotation position is determined accurately based on the sine wave signal and the cosine wave signal of the same amplitude, even if the amplifiers have different operation characteristics.

    摘要: In addition to a knock detection filter, a plurality of optimal knock frequency detection filters (digital filters: BPFs) are provided which filter the signals output from a knock sensor and has mutually different filtering frequency bands. A presently optimal frequency is selected based on the signals extracted by the optimal frequency detection filters, and set as the center frequency of the filtering frequency band of the knock detection filter.

    摘要: A frame transmission device which does not require a separate supervisory line and enables supervisory frames to efficiently enter subscriber traffic for transmission without securing a fixed bandwidth. A supervisory token computing section gives supervisory frames supervisory tokens as permission to transmit within a minimum bandwidth. Subscriber token computing sections give subscriber frames subscriber tokens as permission to transmit within respective set transmission bandwidths. A best-effort token computing section gives the frames best-effort tokens as permission to transmit by using an extra bandwidth. The supervisory or subscriber tokens are given to read frames from a supervisory queue or subscriber queues, and if a frame queue length is smaller than or equal to the best-effort tokens remains in the queue, a queue read control section reads and outputs the remaining frames from the queue by using the extra bandwidth of best-effort tokens.
