摘要:
A unidirectionally-energized brushless DC motor includes a disk attached to a frame, a plurality of plate-like permanent magnets disposed on the disk at equal intervals around the disk, magnetic cores fixed to the frame according to the plurality of permanent magnets, windings each of which is wound around the magnetic core and to which DC power is supplied, a predetermined number of magnetic cores fixed to the frame, and windings each of which is wound around the magnetic core and connected to a power consumption device. The permanent magnets are located such that an angle formed by a straight line passing through the center of the disk and the center of the permanent magnet and a normal line in the center of a magnetic pole plane of the permanent magnet ranges from 0° to 60°.

The invention relates to a connector for use in electrically connecting a ROM or IC card, or the like card to a main printed circuit board of an apparatus. In the connector, a movable member is mounted which causes a contact of the card to be resiliently contacted by a contact of a contactor portion connected to the main printed circuit board when the card is inserted a specified degree, and which causes the contact of the contactor portion to move away from the card a distance greater than the thickness of the card when the card is withdrawn. This arrangement involves no troublesome operation in connection with the expansion and contraction control of the contactor portion and can effectively prevent possible wear and deterioration of the contacts.

A jack having a structure in which a movable contact is driven and separated from a fixed contact when a plug is inserted thereinto and the movable contact is brought into contact electrically with the plug. A free-end part of the movable contact is formed as the plug receptor which is in contact with the inserted plug and is driven by the plug, and both marginal sides of the plug receptor are extended and bent towards the fixed contact to form a pair of holding parts which are provided with flaps extending rearwardly to approach each other. These flaps resiliently hold therebetween the inserted plug. Contact parts are defined at the marginal portions of the holding parts on the side of the fixed contact so as to be in resilient contact therewith.

The present invention relates to an IC card connector in whcih an IC card is inserted into gaps between a contact arrangement surface formed in a housing of the connector, and a pushing plate vertically movable with respect to the housing. After the IC card has been inserted, the pushing plate is pushed toward the contact arrangement surface by pushing mechanisms, so that the IC card is contact-pressed to the contacts on the contact arrangement surface, through the pushing plate. The pushing mechanisms may be formed by, for example, levers rotatable between first positions where the levers cross the pushing plate immediately above the same and second positions where the levers do not cross the pushing plate.

A plug body has, on its front, a cylindrical portion integrally molded therewith and a ferrule is disposed in the cylindrical portion along its axis. The front end portion of the ferrule projects out of the cylindrical portion and the rear end portion is inserted in the plug body. An optical fiber exposed at the front end of an optical fiber cable is fitted in the front end portion of the ferrule and the rear end portion of the optical fiber cable is led out from the back of the plug body.
