    • A main circuit switching unit and an isolator are accommodated in a vacuum container. A first conductor and a main circuit conductor are arranged to extend in and out of the vacuum container. A movable electrode of the main circuit switching unit is connected to the first conductor through a first flexible conductor, and a movable electrode of the isolator is connected to the main circuit conductor through a second flexible conductor. A shield is arranged around the first conductor and the main circuit conductor. Another shield is arranged around a connecting portion between the first flexible conductor and the movable electrode of the main circuit switching unit. A still another shield is arranged around the isolator. A further another shield is arranged around the second flexible conductor. These shields are secured to the vacuum container through insulating spacers. This arrangement instantly eliminates a dielectric breakdown phenomenon that occurs at electric field concentrated regions by the shields to prevent a dielectric breakdown caused by particulate foreign matters and thereby improve an insulation reliability of the devices.

    • A developing device of an electrophotographic copier is structured separably into two mutually attachable and internally connected sections. One of these sections is disposed adjacent to the copier's photoreceptor and contains a developing roller and the other section distal from the photoreceptor is made of a relatively inexpensive synthetic resin material, including a stirrer roller. When the developing agent is spent, the two sections are separated and only the second part with the stirring roller is discarded for replacement. In order that the spent developing agent can be effectively collected, a bar magnet may be inserted into a chamber formed inside the shaft of the stirrer roller to make use of its magnetic force or a scrapper may be provided to scrape off the developing agent remaining attached to the developing roller. In the case of a clam shell type copier with a top part of the main body made openable rotatingly with respect to its base part, the developing device becomes tilted when the copier is opened for its replacement. A device for shaking the tank can effectively cause the developing agent remaining inside to move into the lower section of the device for easy collection.
    • 电子照相复印机的显影装置可分离地构成两个相互连接和内部连接的部分。 这些部分中的一个设置在复印机的感光体附近并且包含显影辊,并且远离感光体的另一部分由相对便宜的合成树脂材料制成,包括搅拌辊。 当消耗显影剂时,两个部分被分离,并且只有第二部分与搅拌辊被丢弃以便更换。 为了有效地收集用过的显影剂,可以将棒状磁体插入到形成在搅拌辊的轴内部的室中以利用其磁力,或者可以提供刮刀以刮除剩余的显影剂 到显影辊。 在蛤壳式复印机的主体的顶部相对于其基部旋转地打开的情况下,当打印复印机进行更换时,显影装置变得倾斜。 用于摇动罐的装置可以有效地使剩余的显影剂移动到装置的下部以便于收集。

    • An oil pressure warning system for an outboard motor for detecting and alarming an abnormal oil pressure of an internal combustion engine, the system including a first oil pressure switch which generates an ON signal when the oil pressure is less than or equal to a first predetermined oil pressure, and a second oil pressure switch which generates an ON signal the oil pressure is less than or equal to a second predetermined oil pressure set higher than the first predetermined oil pressure. The abnormality of oil pressure is detected and alarmed based on the ON signal of the switches. The first and second predetermined oil pressures are determined based on an oil pressure characteristic of a (possible) maximum oil temperature (under which the engine has been warmed up) set relative to the engine speed, thereby ensuring to detect and alarm the abnormality of oil pressure under any engine speed and any oil temperature.
