Title: Generator
Inventor: HOSHI MASAKAZU
IPC: H02P9/08
Filed: 1994-07-05
Abstract: PURPOSE:To provide a generator which can be easily started by reducing the rotational torque of a rotor required at the time of starting the generator. CONSTITUTION:A drive shaft 6 is constituted in such a way that, when the shaft is rotated in one direction, the external thread 6a of the shaft 6 is engaged with the internal thread 7a of a supporting plate 7 and, when the shaft 6 is rotated in the other direction, the external thread 6a is disengaged from the internal thread 7a. Since the magnetic attraction between a rotor 2 and stator 1 drops when the rotor 2 is maintained at a position where the rotor 2 is separated from the stator 1 by turning a handle 9 so that the shaft 6 can rotate in the direction in which the external thread 6a is engaged with the internal thread 7a, the rotational torque of the rotor 2 required at the time of starting a generator can be reduced when the generator is started by turning the handle 9 so that the shaft 6 can be rotated in the direction in which the external thread is disengaged from the internal thread 7a in the above-mentioned state.

IPC: G01N30/00
Filed: 1978-12-12
Abstract: PURPOSE: To discriminate spoiled kerosene simply by passing the kerosene through a substance containing one or more kinds of specified material such as aluminum oxide and silicon oxide.  
     CONSTITUTION: Kerosene is passed through a substance containing at least one or more kinds of aluminum oxide, silicon oxide, magnesium oxide, calcium oxide and calcium chloride. As a result, spoiled components in the kerosene is absorbed away by the substance, which is colored according to the degree of the spoilage. This indicates the degree of the spoilage in the kerosene. For example, a glass tube 2 given a scale is filled with a filler 3 composed of an activated alumina of 60W80 mesh and then, the kerosene is poured through the opening 6 of the column. With the passage thereof, several colored layers are yielded.
