    • An optical disk substrate formed of an aromatic polycarbonate resin obtained by a reaction between an aromatic dihydroxy compound and a carbonate diester and in which the content of undissolved substances that emit light by irradiation with light having a wavelength of 380 nm and have a size of 30 &mgr;m or greater is 100 pieces or less per kg of said resin, and a molding material therefor. According to the present invention, there can be provided an optical disk substrate in which the number of white spots that occur in the passage of a long period of time is very small and the reliability of writing and reading of information is highly stable.

    • This invention relates to the field of electrical connectors, and particularly concerns electrical connectors with multiple contacts requiring keying of the mating connector parts. With prior art devices, when more than one connector pair is used in a system, different connector parts must be chosen which have a different keying configuration for the key and groove. With another prior art device, which uses a single type connector part, it is necessary to sacrifice one contact position in the connectors. The present invention overcomes the deficiencies of the prior art noted above by providing a keying device which permits manufacture and production of a single type of male or female connector part and yet does not require the sacrifice of contact positions within the connector parts to effectuate the keying. The invention therefore provides an improved connector keying device for keying mating first and second connector parts to assure proper connection between the parts and to prevent connection to other connector parts of unlike keying. In accordance with the invention, there is provided a key mount affixed to the first connector part and adapted to receive a key member mounted thereto. An appropriate key member is removably attached to the key mount. A key member receiver is mounted on the second connector part and has a key member-receiving slot therein aligned with and slidingly receiving the key member when the first and second connector parts are mated.
    • 电连接器领域本发明涉及电连接器的领域,特别涉及具有多个触点的电连接器,需要键合配合的连接器部件。 对于现有技术的装置,当在系统中使用多于一个连接器对时,必须选择不同的连接器部件,其具有用于键和槽的不同的键控构造。 对于使用单一型连接器部件的另一现有技术装置,必须牺牲连接器中的一个接触位置。 本发明通过提供一种能够制造和生产单一类型的公或母连接器部件并且不需要牺牲连接器部件内的接触位置来实现键控来克服上述现有技术的不足之处, 。 因此,本发明提供了一种改进的连接器键控装置,用于将第一和第二连接器部件配合在一起,以确保部件之间的正确连接并防止与不同键合件的其它连接器部件的连接。 根据本发明,提供了一种固定在第一连接器部件上并适于容纳安装在其上的键构件的键座。 一个适当的键构件可拆卸地连接到钥匙座上。 钥匙构件接收器安装在第二连接器部分上,并且当第一和第二连接器部件配合时,其中具有与其成对准并滑动地接收钥匙构件的键构件接收槽。

    • An electrical connector for removable connection with a plurality of spaced conductors in a flat strip, such as a length of ribbon wire. The connector includes a housing containing a plurality of contacts and a conductor supporting member movable relative to the housing between an insertion position and a clamping position. The contacts and the conductors supporting the member define a plurality of conductor-receiving passages, the passages becoming smaller in size when the supporting member is moved from the insertion position to the clamping position. The conductors of a flat strip may be easily inserted into the passageways when the supporting member is in the insertion position, and the conductors are securely clamped between the contacts and the supporting member when the supporting member is in the clamping position.
    • 一种电连接器,用于与扁平条中的多个间隔的导体(例如一段带状导线)可移除连接。 连接器包括容纳多个触点的壳体和可在插入位置和夹紧位置之间相对于壳体移动的导体支撑构件。 支撑构件的触点和导体限定多个导体接收通道,当支撑构件从插入位置移动到夹紧位置时,通道的尺寸变小。 当支撑构件处于插入位置时,扁平条的导体可以容易地插入到通道中,并且当支撑构件处于夹紧位置时,导体牢固地夹在触点和支撑构件之间。
