摘要： PURPOSE:To set the direction of the screen easily in an optional direction with simple structure by coupling a stationary base and a television support with a ball joint. CONSTITUTION:A screw 9b of a ball joint 9 is fixed to a screw hole 11a of a support plate 11. The ball joint 9 is fixed to the joint 7a of a base 7 by screwing a ball joint fix screw 10 to the joint 7a of the base 7. A base fix screw 8 is loosened to widen the inner diameter of a stay throughhole 7b of the base 7 and the base 7 moves the perpendicular part 4b of the stay 4 vertically. Simultaneously, the base 7 is turned around the perpendicular part 4b of the stay 4. The ball joint fixed screw 10 is loosened to allow a television set 13 to be directed in any direction around the center of the ball of the ball joint 9.

摘要： PURPOSE:To provide a portable generator which has a small size but high reliability, by moving the fuel in a lower chamber to an upper chamber by means of a pump operting an in resonance with vibration generated by an internal combustion engine, and feeding the fuel from the upper chamber to the internal combustion engine. CONSTITUTION:A fuel tank 36 is provided with a pipe 38 serving as a fuel feed port at its side slightly above the center in the direction of height. The pipe 38 is communicated with the fuel flow-in port of a carburetter 34 through a fuel feed pipe 32. Through action of a vibrator 80 vertically moving in resonance with vibration generated by an internal combustion engine 16, the fuel in a lower chamber 52 gradually flows in an upper chamber 50, and is fed through the pipe 38 to the internal combustion chamber 16. Thus, a fuel feed port can be provided in relatively high position of the fuel tank 36, allowing the fuel tank 36 to be located in low position, resulting in reduction of the total size of a portable generator.
摘要翻译：目的：提供一种便携式发电机，它具有体积小但可靠性高的特点，可以通过一个与内燃机产生的振动共振的泵将下腔室的燃料移动到上腔室，并将燃料从上腔室到内燃机。构成：燃料箱36在其高度方向稍微高于中心的一侧设置有用作燃料供给口的管38。管38通过燃料供给管32与化油器34的燃料流入口连通。通过与内燃机16产生的振动共振垂直移动的振动器80的作用，下室52中的燃料在上部室50中逐渐流动，并且通过管38被供给到内部燃烧室16.因此，可以在燃料箱36的较高位置设置燃料供给口，从而允许燃料箱36位于低位置，导致便携式发电机的总体尺寸减少。

摘要： PURPOSE:To reduce the cost of a brushless AC generator and to sufficiently increase the strength of the generator by providing an armature and a field at a stator side and composing a rotor only of a laminated core. CONSTITUTION:A nonmagnetic piece 2 is fixed to a rotor shaft 1, and semicircular rotor cores 3A, 3B are fixed to be disposed at both sides of the piece 2. A stationary core 4 is disposed on the outer periphery of the rotor. Two field poles P and armature tooth part T are alternately arranged on the inner periphery of the core 4. A field coil 5 is wound on the field pole P, and an armature coil 6 is mounted on the armature toothed part. With this structure, the rotor does not use coil nor permanent magnet but is constructed simply to interpose the piece 2 between the cores 3A and 3B. Accordingly, its cost can be reduced.

摘要： PURPOSE:To prevent unnecessary thermogenesis in magnetic field coil by making easier the establishment of voltage by strengthening the excitation force of magnetic field coil only at the time of voltage establishment. CONSTITUTION:At the time of voltage establishment, the closed contact 10 and the movable contact 9 of the relay 7 are in contact with each other, so that voltage whose full-wave is rectified by the full-wave rectifying bridge 5 is supplied to the magnetic field coil 4. When the terminal voltge of the armature 1 reaches a predetermined value by establishment, the closed contact 10 of the relay 7 is separated from the movable contact 9, and thus full-wave rectified voltage through the rectifier 3a and the full-wave rectifying bridge 5 is supplied to the magnetic field coil 4.
