摘要:
A contact-breaker device that can be miniaturized, realize low power consumption and low cost, and generate an irregular pulse current by causing irregular electrical conduction and insulation of a circuit. The contact-breaker device comprises: fixed terminals 12A and 12B secured at positions spaced apart from each other; and a movable member 11 capable of moving relative to the fixed terminals 12A and 12B and coming into or avoiding contact with the fixed terminals 12A and 12B based on its movement, thereby causing electrical conduction or insulation between the fixed terminals 12A and 12B; wherein the movable member 11 irregularly moves in accordance with externally applied vibration, thereby causing irregular electrical conduction or insulation between the fixed terminals 12A and 12B.

An electronic toothbrush including a head portion at one end which is studded with bristles, a grip portion in the middle which contains a battery, and a voltage tester at the other end which is separable from the grip portion and has a tester body with coupling means associated with the grip portion for separably coupling the tester body with the grip portion. The grip portion has a first electrically conductive member which is adapted to be touched by a user and is electrically connected to one pole of the battery, and a second electrically conductive member which is adapted to be electrically connected to the bristles and is electrically connected to the other pole. The tester has a light emitting member mounted inside the tester body and visible from outside the tester body, and a pair of electrical conductors extending from the light emitting member and being exposed at least partially from the tester body. When the pair of electrical conductors of the tester separated from the grip portion contact the first and second conductive members of the grip portion, the emission of light by the light emitting member is determined by the condition of the battery.

An ion toothbrush which can be tested on the supply voltage by turning on a switch, and concerning which assembling steps are simplified. This ion toothbrush comprises: a head (50) with brush bristles (51) implanted therein; a handle (10); and a battery (14) received in the handle (10). One electrode of the battery (14) is conductively connected with the external surface of the handle (10), and the other electrode is conductively connected with the vicinity of the implanted area of the brush bristles (51) at the head (50). This ion toothbrush further comprises: an LED (18) with its one terminal (18B) connected to one electrode of the battery (14), and with the other terminal (18A) connected to the other electrode of the battery; a spindle capable-of conductively connecting the other electrode of the battery. (14) with the vicinity of the implanted area and also capable of conductively connecting with the terminal (18A); and a switch (22) for opening or closing an electric circuit containing the LED (18), the spindle (26), and the battery (14).
摘要:
A cleaning tool which uses a disposable adhesive sheet, where the adhesive sheet which is the surface layer of an adhering roller may be peeled and torn in a simple and easy manner without causing the user annoyance or discomfort. The cleaning tool has an adhering roller with an adhesive sheet wound in layers thereon and supported rotatably about an axis. The adhesive sheet forming the surface layer of the adhering roller is peelable from the portion of the adhesive sheet forming the layer thereunder and torn at least in the direction of the width thereof. A stopper means for stopping rotation of the adhering roller is provided.
