    摘要： An object of the present invention is to provide a rotary encoder that has a code member which rotates so as to draw an accurate circle as a shaft rotates. Such rotary encoder includes a casing; a detection element attached to the casing; and a rotatable rotor having a mounting aperture for inserting a shaft at the center thereof and being provided with a code member opposing to the detection element, in which an inner peripheral surface of the mounting aperture is provided with a spring member having a base and a plurality of tongues for energizing the shaft toward the center of the mounting aperture so as to set a position of the shaft at the center of the mounting aperture.

    摘要： A rotational angle detecting device includes a rotation detecting section for outputting sinusoidal first and second detection signals as a result of the rotation of a rotor connected to a rotary member, a storage section for updating and storing the first and second detection signals, and a controlling section. The first and second detection signals have constant amplitudes, have the same periods, and have wavelengths which are output of phase. The controlling section compares the amplitude values of most recent first and second detection signals output from the rotation detecting section, and determines whether or not the amplitude values fall within proper ranges. When the controlling section determines that they fall within the proper ranges, a piece of detection information which is created based on the most recent first and second detection signals is supplied to a controller. On the other hand, when the controlling section determines that they do not fall within the proper ranges, the controlling section destroys the most recent first and second detection signals, and does not supply detection information to the controller. The invention provides a rotational angle detecting device for performing required controlling operations using detection signals output from the rotational detecting section which have been determined as being proper detection signals.

    摘要： There is provided a variable resistor comprised of a resistor formed at a movable member arranged to be reciprocatable, and a slider element attached to a fixing member fixed in opposition to the movable member, slidingly contacted with the resistor. The resistor has the first resistor, the second resistor and the third resistor extending in a reciprocating direction of the movable member and electrically independent from each other, a first resistor pattern having one end of each of the first resistor and the second resistor connected to each other, a second resistor pattern having the other ends of the second resistor and the third resistor. The slider element is comprised of the first slider element, the second slider element and the third slider element slidingly contacted with the first resistor, the second resistor and the third resistor. When the movable member is moved in the direction of arrow A, a resistance value between the first and second slider elements is increased and a resistance value between the second slider element and the third slider element is decreased, and in turn when the movable member is moved in a direction of an arrow B, a resistance value between the first slider element and the second slider element is decreased and a resistance value between the second slider element and the third slider element is increased.

    摘要： The present invention relates to an asynchronous access system for accessing a shared storage in a multiprocessor system in which a plurality of processor modules and shared storage modules are connected through a system bus. The present invention accesses the shared storage at a high speed and reduces the overhead of the system bus. The present invention recognizes in write and read instructions serial access addresses of the shared storage, requests a block access in which a predetermined number of words are grouped as one block, and performs a recovery process when a write instruction is executed abnormally in the block access.
