    • A high-frequency motor comprises a squirrel-cage rotor. The rotor comprises an iron core having a plurality of circular slots, a plurality of conductive rods inserted into the slots, and short-circuit rings disposed at both ends of the conductive rods. The conductive rods are made of copper. A ratio of a product of the number N2 of the conductive rods and a diameter d2 of each conductive rod to an outer diameter D of the rotor is in an optimized range of 1.1 to 1.5, namely, 1.1.ltoreq.N2.multidot.d2/D.ltoreq.1.5. With this optimization, it becomes possible to achieve a maximum rotational speed of more than 120,000 min.sup.-1 and obtain an excellent motor efficiency.
    • 高频电动机包括鼠笼式转子。 转子包括具有多个圆形槽的铁芯,插入槽中的多个导电棒和设置在导电棒两端的短路环。 导电棒由铜制成。 导电棒的数量N2与导电棒的直径d2与转子的外径D之比为1.1〜1.5的优化范围,即1.1×10 / = 1.5。 通过该优化,可以实现大于12万分钟-1的最大转速,并获得优异的电动机效率。

    • Copying apparatus is constituted by a photosensitive member having a photochromic characteristic when changes light transmitibility when projected with light reflected by a manuscript. A light source is provided for projecting a photo-image formed on the photosensitive member onto a photosensitive recording sheet through the photosensitive member. In a modified embodiment, the copying apparatus has a construction substantially the same as the conventional electrophotographic copying machine except that a photosensitive drum is made of transparent material and covered by a thin transparent photoconductor. Consequently a toner image corresponding to the photo-image of a manuscript is formed on the photosensitive drum. A light source is provided for projecting the toner image on a photosensitive recording sheet.
    • 复制装置由具有光致变色特性的感光构件构成,当通过原稿反射的光投射时,透光性变化。 提供光源,用于通过感光部件将形成在感光部件上的光图像投影到感光记录片材上。 在改进的实施例中,复印装置具有与常规电子照相复印机基本相同的结构,只是感光鼓由透明材料制成并被薄的透明感光体覆盖。 因此,在感光鼓上形成对应于原稿的照片的调色剂图像。 提供光源以将调色剂图像投影在感光记录片材上。

    • A centrifugal compressor of the type in which disassembly and assembly of the compressor is effected by taking out and inserting internal component parts including end walls for closing ends of a cylindrical rotor chamber wall from and into a cylindrical rotor chamber in the axial direction thereof, including intake chamber side communication holes communicating with an intake chamber formed within the cylindrical rotor chamber and a propelling force balance chamber side communication hole communicating with a propelling force balance chamber formed within the cylindrical rotor chamber. The intake chamber side communication holes are formed in the internal component part and in the cylindrical rotor chamber wall, respectively. The propelling force balance chamber side communication holes are respectively provided in an inner axial end surface of the cylindrical rotor chamber wall and an end wall removably fitted in the cylindrical rotor chamber wall with a portion of the end wall abutting the inner axial end surface of the cylindrical rotor chamber wall. The intake chamber side communication hole and the propelling force balance chamber communication hole provided in the cylindrical rotor chamber wall are communicated with each other through a balance pipe mounted on an outer surface of the cylindrical rotor chamber wall.
