摘要： A linear scale attachment device for holding and securely attaching a linear scale on an object to be measured is disclosed. The device includes an aluminum base formed with a holding groove having a larger opening than the width of a linear scale that is fitted in this groove, and a retainer for preventing the linear scale fitted in the holding groove from falling off. The base is permanently attached to the object at one location in the lengthwise direction, and resiliently attached at one or more other locations such as to be pressed in the X and Y directions using a cantilever plate spring. While using an aluminum base, the attachment device allows easy attachment and maintenance of the scale and relieves the effect of thermal stress caused by a difference in the thermal expansion coefficient between the aluminum base and the object.

摘要： A turbo vacuum pump has a rotor and magnetic bearings. The magnetic bearings are held in a housing having a suction port and an exhaust port, and support the rotor rotatably. A peripheral flow pump stage and screw pump stage are formed in the rotor, so that the pressure at the exhaust port can be at or near atmospheric pressure level. Before starting the turbo vacuum pump, the magnetic bearings are operated to displace a rotor position and to scrape off the reaction products which have deposited inside the pump. In addition, before starting the turbo vacuum pump, a stator of the pump is heated up to decrease a binding force of the reaction products. Therefore, the pump can be restarted, even if the rotor has locked by the solidification of deposited reaction products formed during stopping of the pump.
摘要翻译：涡轮真空泵具有转子和磁性轴承。磁性轴承保持在具有吸入口和排气口的壳体中，并且可旋转地支撑转子。在转子中形成有外围流动泵级和螺杆泵级，使得排气口处的压力可处于或接近大气压力水平。在启动涡轮真空泵之前，操作磁性轴承以移动转子位置并刮掉沉积在泵内的反应产物。另外，在启动涡轮真空泵之前，泵的定子被加热以降低反应产物的结合力。因此，即使转子已经通过在泵的停止期间形成的沉积的反应产物的凝固而被锁定，泵也可以重新启动。

摘要： In an optical encoder using a collimated lighting system, an index scale is inclined toward a main scale by a predetermined value. With this arrangement, a component of variation in the detection signal due to variations in the grating gap can be offset or integrated to be removed from a geometric image of the first grating in the detection signal, whereby the dependence of an S/N ratio of the detection signal on the grating gap can be avoided.

摘要： There is disclosed a supercharger for an engine in which intake air is increased in pressure by the use of exhaust gas flowed into the supercharger from the engine, and is fed to the engine. An impeller 2, having a plurality of blades formed on an outer peripheral portion thereof, is received within a casing 1, and a ring-like fluid passage is formed around the plurality of blades, and a first partition 3 and a second partition 4 are provided in the fluid passage to divide this fluid passage into two fluid passages, that is, an exhaust gas passage 6 and an intake air passage 9. There is provided a fluid machine construction for causing the exhaust gas of the engine to flow into and out of the exhaust gas passage, and for causing the intake air to flow into and out of the intake air passage. With this construction, the pressure of the intake air can be satisfactorily increased over a wide range of the engine speed from a low speed to a relatively high speed, and therefore the supercharging of the engine can be effected with the inexpensive machine construction.
