To provide a junk mail rejection system which can effectively reject junk mail in electronic mail. When junk mail transmitted from many and unspecified persons is sent to a first electronic mail address registered in a first mail distribution service center, sources of the junk mail are not acceptable electronic mail addresses, and a reception enable unit rejects receiving the junk mail, thereby avoiding transmission of the junk mail to subscribers. On the other hand, the electronic mail transmitted from many and unspecified persons and not to be rejected by the reception enable unit is transmitted to a second electronic mail address. The electronic mail to the second electronic mail address received by a second mail distribution service center is forwarded to a third mail distribution service center, and a replacement unit replaces a source with an acceptable electronic mail address registered in the first mail distribution service center, and the electronic mail is transmitted to the first mail distribution service center. Since the source is set to an acceptable electronic mail address, the reception enable unit in the first mail distribution service center enables reception, and a subscriber can receive the electronic mail.

An anti-theft apparatus for use in a vehicle-mounted electronic component includes a removable control panel. Protrusions on a first side of the control panel engage holes in a first side of an equipment body of the electronic component and function as hinges as the control panel is rotated to a mounted position. A first electrical connector on the equipment body engages a second electrical connector on a rear surface of the control panel and a biasing member exerts a force against the rear surface of the control panel. The control panel includes a recess in a second side into which a locking protrusion of a locking mechanism in the equipment body extends. A button actuates the locking mechanism retracting the locking protrusion and allowing the biasing member to eject the control panel from the equipment body. The locking protrusion is retracted by a sliding cam or directly by depression of the button. Another embodiment includes a concavity in the control panel which engages a deflectable protrusion on the equipment body after the release button is depressed so as to retain the control panel in an ejected position for removal by the user. Elastic members engage the protrusions of the control panel providing a click feel during removal and retain the control panel in the ejected position. Another embodiment includes an elastic protrusion in the equipment body which engages a corresponding concavity in the front panel to retain the front panel in an ejection position.

Vehicle-mounted equipment anti-theft mechanism

When an operating unit (10) of a vehicle-mounted electronic equipment is attached to its equipment body (20), a first engaging portion (18) and a second engaging portion (24) of engaging means are engaged and the operating unit is turned around the engaging means in a direction in which the operating unit contacts the equipment body substantially completely. In this case, a releasing member (11) moves a locking member (4) to a releasing position. Under such situation, a locking portion (7) of the operating unit and a locking portion (6) of the equipment body are aligned in position. The locking member (4) is then turned to a locking position where the locking means is locked to thereby complete the attachment of the operating unit to the equipment body. When the operating unit is to be removed from the equipment body, the releasing member (11) is operated to release the restriction of the locking member (4) by a restricting member (3), and the locking member is turned in a releasing direction to thereby release the locking means and hence remove the operating unit from the equipment body.

A method of producing a superconducting cable or a coil including an A-B-C-D system superconductor where the A includes an element of group IIIa of the Periodic Table, the B an element of group IIa of the Periodic Table, C copper, D oxygen. A plurality of filaments are selected from a copper alloy filament including: a copper alloy filament including the A element; copper alloy filament including the B element; a copper alloy filament including both the elements the A and the B; a first metallic filament having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a second metallic filament coated with an oxide layer; a copper filament containing the A element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a copper filament containing the B element and having particles of a copper oxide, copper halide or copper sulfide dispersed therein; a third metallic filament containing the A element and coated with an oxide layer; a fourth metallic filament containing the B element and coated with an oxide layer; the first to fourth metallic filaments being substantially free of any component which provides an adverse effect on the production of the superconductor. The selected filaments are arranged to form element filaments bundle so that the superconductor is produced in a subsequent heat treatment. The bundle is drawn and then heated under an oxidizing atmosphere for producing the superconductor.

A laminated insulation paper of the type having two cellulose layers separated by a plastic layer is formed with through holes in the plastic layer such that the respective cellulose layers may contact one another through the through holes. The insulation paper is formed by pressing heated, rounded pins into one of the cellulose layers while backing the other layer until the two cellulose layers are contacted through the hole thus formed in the plastic layer.

Apparatus for continuously vulcanizing a covered material on a conductor comprises a feed device for feeding the conductor in one direction at a constant speed and an extruder for applying the covered material to the conductor fed from the feed means. A vulcanizing tube extends from the extruder, the cable passing through the vulcanizing tube. The vulcanizing tube has a curing section extending from its inlet to a location intermediate its inlet and outlet. A take-off device is disposed forwardly of the vulcanizing tube for hauling the cable. A load applying device is disposed between the extruder and the take-off device for applying a load to the traveling cable at a location forwardly of the curing section of the vulcanizing tube, so that a tension exerted on the cable in a direction opposite to the direction of travel of the cable is applied to the traveling cable.
