摘要： A linear actuator unit has a slide plate which is allowed to freely move along the outer rail while causing a cover to retreat. The linear actuator unit includes: an outer rail, which is formed into a cylindrical shape, and includes the slit-opening portion formed along an axial direction thereof; the slide plate (3), which is coupled to an inner block in the hollow portion through the slit-opening portion; a cover belt, which is tensioned between both ends in a longitudinal direction of the outer rail so as to cover the slit-opening portion; a belt-guiding member, which separates the cover belt from the outer rail correspondingly to movement of the slide plate; and a seal member, which seals between the belt-guiding member and the cover belt and between the belt-guiding member and the outer rail.

摘要： A track rail is composed of a pair of rail members in which rolling contact surfaces for rolling bodies are formed, respectively, and a rail housing equipped with a pair of rail mounting grooves in which those rail members are fitted, respectively. Each of the rail members is fixed within a corresponding one of the rail mounting grooves via an adhesive layer. A reference projection, formed on a bottom of one of the pair of the rail mounting grooves, is in contact with a corresponding one of the rail members without the intermediary of the adhesive layer. The rail member fitted in the one of the rail mounting grooves is adhesively fixed in a state of being abutted against the reference projection. The rail member fitted in the other rail mounting groove is adhesively fixed at a predetermined distance from the reference projection.

摘要： A PWM control circuit, microcomputer and electronic equipment which can generate high-resolution PWM signals through a small-sized scale of circuit. The PWM control circuit includes a PWM period value setting register, a counter, an edge-point value setting register, a PWM output circuit for varying the level of the PWM signal at a first edge-point, and a delay value setting register provided on low order side of the edge-point value setting register, for specifying a delay time of the first edge-point. The PWM output circuit delays the first edge-point by a period smaller than one clock period of CLK, in accordance with the value in the delay value setting register. This can improve the resolution of the PWM signal. One-bit or two-bit value is stored in the delay value setting register. Based on the stored value, the first edge-point can be delayed by ½, ¼, 2/4 or ¾ clock period.

摘要： A return pipe is constituted by combining a pair of return pipe halves split along a non-load passage. A pipe hold down member is fixed to a nut member so as to be astride the return pipe, fixing the return pipe to the nut member. A flange portion is formed on each of the return pipe halves, while a pair of fixing leg portions covering the flange portion of each return pipe half is formed on the pipe hold down member. Fastening members pass through the fixing leg portions of the pipe hold down member and the flange portion of the return pipe halves and are fastened to the nut member. When the fixing leg portions of the pipe hold down member are fixed to the nut member by the fastening members, an engagement portion of the pipe hold down member is configured to tighten the pair of the return pipe halves in the direction where split faces of the return pipe halves abut against each other.
