IPC: H01H50/02
Filed: 1999-12-07
Abstract: PURPOSE: An electromagnet fixing structure of an electromagnetic relay and a method of fixing the electromagnet are provided to increase an attraction force of an electromagnet exerting on the armature without an increase of cost, and to manage the thick dimensions when the yokes are manufactured. CONSTITUTION: An electromagnet fixing structure for the electromagnetic relay fixes a yoke(11) and an iron core(12), which form an electromagnet. In the fixing structure, a yoke(11), shaped like L, includes a bent surface portion(111). A rectangular through hole(112) is formed in the central portion of the bent surface portion(111). A rod-like iron core(12) is formed which has a cross section larger in the longitudinal direction than the rectangular through hole(112). A protruded portion(121) of which the end face(121a) is somewhat smaller than the through hole(112) is formed at the central portion of one end of the iron core(12). The yoke(11) and the iron core(12) are fixed by inserting the protruded portion(121) into the through hole(112). Circular holes(113,114) are formed in the yoke(11). A flange(122) is formed at the other end of the iron core(12), while being separated from and facing the bent surface portion(111). A length(L121) of the protruded portion(121) is selected to be longer than a length(L112) of the through hole(112). The yoke(11) and the iron core(82) in the electromagnet fixing structure are used together with a coil block(13) which includes a cylindrical bobbin(131) on which a coil(132) is wound and a pair of coil terminals(133) electrically connected to the coil(132), whereby an electromagnet is formed. Here, the yoke(11) and the iron core(12) are both fixed temporarily.

Abstract: PURPOSE: A compressor supporter is provided to minimize noise and vibration by restraining contacting of a damping unit and a stand where noise and vibration of a compressor are transmitted to the damping unit. CONSTITUTION: While a compressor is installed on a base plate(20), a retaining part(33) of an elastic damping unit(30) inserted to a stand(22) fixed on the base plate supports the compressor. Diameter(2R) of a through hole(31) of the damping unit corresponding to the retaining part is larger than diameter(2r) of the stand. Thus, the damping unit doesn't contact with the stand. Therefore, noise and vibration of the compressor transmitted to the retaining part are sufficiently damped by the damping unit without transmission to the stand. Therefore, vibration and noise of a product using the compressor are reduced.

Abstract: PURPOSE: Provided is a bean curd vending machine for conveniently supplying various kinds of bean curd to consumers at a near area of one's residence in order to meet various tastes of consumers. CONSTITUTION: When a consumer pushes a selection button, a withdrawing means(18) is rotated so that an operating plate(22) installed movably at the lower part of each separating plate for preventing the dropping of a cake of bean curd is opened. Right after dropping a cake of bean curd corresponding to cash input, a solenoid valve(21) regulates an interrupter plate(24) to exactly control the number of cakes of bean curd to be vented. In the case that the bottom of a casing(25) is closed with upwardly drawing the operating plate(22), the solenoid valve(21) operated by electric force draws the interrupter plate(24) so that another cake of bean curd is placed between the interrupter plate(24) and the operating plate(22) for the next vent.

Abstract: PURPOSE: A linear movement motor using electro-magnet is provided to reduce parts count and cost by eliminating the device for converting rotational movement of the motor into a linear movement, while preventing noise and vibration caused due to rotation of the motor. CONSTITUTION: A linear movement motor comprises an assembly of a permanent magnet or an electro-magnet(1) which moves in a linear fashion by using a repulsive force or attracting force between magnetic poles. When the electro-magnet moves in the left direction, the magnetic pole is changed through a switch or a sensor before the electro-magnet contacts the left N-pole. When the electro-magnet moves in the right direction, the magnetic pole is changed before the electro-magnet contacts the right N-pole. In this manner, a high speed reciprocating linear movement is obtained without causing noise or vibration.
