Abstract: In a holder and a structure for organizing excess length by winding cables and the like, an excess length organizing holder comprises a baseboard which has a rotation axis vertical to a fixed plane, and a spool which has a flange whose edge is provided with two incisions and a winding portion. The spool is rotated around the rotation axis in a state where a cable is folded by way of the winding portion and the two incisions, thereby winding the cable twofold around the winding portion. Also, an excess length organizing structure comprises a door detachable from a box-shaped rack, a mounting hardware connecting the door to the rack and pivoting on one side so as to make the door openable and closable, and at least one excess length organizing holder mentioned above whose baseboard is attached on a surface of the door when the door is attached to the mounting hardware.

Abstract: An outdoor installation type cabinet which accommodates electronic equipment has a number of thin tubes which form an outside air passage and outside air is allowed to flow in the outside air passage by operating an external fan. A heat exchanger which is spaced from each wall of the cabinet is provided at a midway portion of the outside air passage to perform heat exchange between the outside air flowing in the outside air passage and inside air present in the equipment accommodating portion. A circulating fan is installed in the equipment accommodating portion to circulate the inside air. A bimetal is mounted on each side wall of the cabinet to detect a temperature of each side wall and control operations of the external fan, the circulating fan, and an internal fan according to the temperature detected.

Abstract: A device for providing an earth connection in a metal core printed circuit board (2) which is assembled in a shield casing (1) and which has an earth pattern (23) and a metal core (21), includes conductive connecting members (3) having one end soldered to the earth pattern (23) and another end in surface contact with the metal core (21) and the shield casing (1).
