    摘要： The vibration and noise excited by the electromagnetic exciting force in the radial direction of an electric motor are suppressed.In an electric motor 100, a rotor 1 is divided into four rotor pieces 3, 4, 5, and 6 for an axial length of 2L of one group of the rotor core, and for example, the four rotor pieces 3, 4, 5, and 6 are ideally 0.29L, 0.71L, 0.71L, and 0.29L in axial length in the axial direction, and permanent magnets 2 of the rotor pieces 3, 4, 5, and 6 are arranged in the circumferential direction so that the phase differences of the electrical angle are 0, π, 0, and π. Further, when an effect is obtained even if the ideal axial length is changed, the tolerance of the aforementioned axial length is ±0.1L.

    摘要： A memory device has a variable storage capacity depending on the object of use by a user, thereby improving convenience in use of the device. The memory device has a casing which may be loaded into host equipment. The casing has a plural number of loading sections in each of which a memory chip can be mounted. The casing carrying the memory chips has a terminal unit at the end insertable in the host equipment. Data readout from or writing into the memory chip is controlled by a semiconductor unit forming a control circuit disposed in the casing. The memory device may be of a recording capacity as desired by a user by changing the number of the memory chips mounted in the loading sections or by mounting memory chips of variable recording capacities in the loading sections.

    摘要： An internal combustion engine with dry sump lubricating system includes a feed pump which supplies lubricating oil from a lubricating oil tank disposed outside an engine body to all moving parts in the engine. After circulating through the engine, the lubricating oil drops down into a crank chamber and is immediately picked up from the crank chamber and sent back into the lubricating oil tank by a recovery pump. Since the lubricating oil tank is attached to an end of the engine body from which a crankshaft project, it does not increase the overall width (dimension in the direction perpendicular to the axis of the crankshaft) and height of the engine. Even when the engine has inclined cylinders, the lubricating oil tank can avail a high degree of design freedom because the end face is not influenced by inclination of the cylinders as greatly as side surfaces of the engine body. The engine also includes a breather system so designed as to prevent an operation failure of the engine which would otherwise be caused due to inflow of the lubricating oil into an intake system of the engine.

    摘要翻译： 具有干式油底壳润滑系统的内燃机包括供给泵，其将设置在发动机外部的润滑油箱的润滑油供给到发动机中的所有运动部件。 在通过发动机循环后，润滑油下降到曲柄室中，并立即从曲柄室拾起并通过回收泵送回润滑油箱。 由于润滑油箱安装在发动机主体的从曲轴突出的端部，所以不增加总体宽度（与曲轴的轴线垂直的方向的尺寸）和发动机的高度。 即使发动机具有倾斜气缸，润滑油箱也可以具有高度的设计自由度，因为端面不受发动机主体侧表面极大的气缸倾斜的影响。 发动机还包括通气系统，其被设计成防止由于润滑油流入发动机的进气系统而引起的发动机的操作故障。
