    • In a linear pulse motor which includes: a movable body having an iron core provided with a coil or coils and side plates for supporting the iron core; a stationary body having magnetic circuit forming means for forming a magnetic circuit with the iron core across an air gap between the iron core and the magnetic circuit forming means; an axle fixed to the movable body, and wheels supported rotatably on end portions of the axle, respectively, and rollable on and along the stationary body; wherein the coil or coils are energized by pulses of a predetermined drive frequency to impart a stepwise magnetic drive force to the movable body, the length of the axle between the wheels is so determined that a noise level peak frequency or resonant frequency of the movable body is sufficiently far from the predetermined drive frequency.

    • A cooling structure for a multi-cylinder piston-engine cylinder block includes a side coolant gallery distributing coolant into a water jacket surrounding a group of cylinders arranged from upstream to downstream. The flow cross-section of the coolant gallery decreases toward its downstream end. The water jacket has a water jacket wall which constitutes part of the coolant gallery. The water jacket wall includes a group of coolant inlets, each of which directs coolant towards the upper part of each of the cylinders. At least one coolant inlet is offset from the center of the corresponding cylinder toward a clearance between adjoining cylinders. This cooling structure can cool all of the cylinders uniformly and the entire surface of each cylinder evenly.
    • 用于多缸活塞 - 发动机气缸体的冷却结构包括侧冷却剂箱,其将冷却剂分配到围绕从上游到下游布置的一组气缸的水套中。 冷却剂流道的流动横截面朝向其下游端减小。 水套有一个水套壁,构成冷却液库的一部分。 水套壁包括一组冷却剂入口,每个冷却剂入口将冷却剂引导到每个气缸的上部。 至少一个冷却剂入口从相应气缸的中心偏移到相邻气缸之间的间隙。 这种冷却结构可以均匀地冷却所有气缸,并且每个气缸的整个表面均匀。
