    摘要: An optical data bus fixing board suitable for using an optical data bus as a signal transmission medium and an optical back plane board. A recess for inserting an optical data bus, which is made of a rectangular light transmissive resin substrate and comprises a step-wise side along the longitudinal direction and signal light incoming/outgoing areas formed by sloping the longitudinal end of each step at 45 degrees in relation to the substrate surface, is formed in the surface of a flat plate in order to easily and efficiently use the optical data bus as a signal transmission medium for interconnecting various signal processing circuits. The optical data bus is inserted and fixed within the recess by being pressed and biased from the back end by a first holding member including a reflective diffusion plate and from the side by a second holding member including a flat spring.

A stationary slit plate 4 includes a slit row R2 in which a plurality of light transmissive slits S3 each having a slit width of 180° in terms of electrical angle and a plurality of light non-transmissive slits S4 each having a slit width of (360Xk-180)° in terms of electrical angle are alternately formed. k is a value that satisfies k=1±(⅓n) where n denotes the number of the light transmissive slits S3.

    摘要: A magnetic absolute encoder with enhanced resolution is provided. A first cycle determining section 27 utilizes data stored in a fourth angle data storing section 23 to determine in which cycle of m cycles of the fourth angle data, fifth angle data, which has been newly computed in response to rotation of a rotary shaft 1, occurs. A second cycle determining section 29 determines in which cycle of n cycles of first angle data that occur in first determined cycle, the newly computed fifth angle data occurs. A third cycle determining section 31 determines in which cycle of N1 cycles of the first angle data, the current first angle data occurs, based on the first determined cycle and second determined cycle. An absolute position determining section 33 determines the absolute position based on third determined cycle and the digital value of the current first angle data.

    摘要: A wheel velocity signal for each wheel detected by a wheel velocity sensor is input to a bandpass filter. Signals from frequency bands unrelated to the unsprung resonance are then removed from the wheel velocity signal and only signals from frequency bands related to the unsprung resonance are output. A road surface &mgr; gradient estimation device uses an online identification method to identify an damping ratio of a second order resonance model similar to a suspension—tire resonance model from the signal output from the bandpass filter. The road surface &mgr; gradient is then estimated from the identified damping ratio. The damping ratio of the second order resonance model corresponds to the road surface &mgr; gradient in the following manner: when the damping ratio is identified as being small, the road surface &mgr; gradient is estimated as being large; and when the road surface &mgr; gradient is identified as being large, the damping ratio is estimated as being small.
