In order to efficiently cool highly heat generating components mounted on an electronic device, it is necessary to provide a large heat sink, which is the heat dissipation member, and this entails the problem of an enlarged device size and accordingly an increased installation space. A heat receiving member is attached to a heat generating component installed in a housing, a fan for discharging air within the housing out of the housing is attached on a part of a wall of the housing, a heat sink having a base and fins arranged on the base is attached opposite the fan on an outer face of the wall of the housing or protruding out of the wall with the fins facing the housing, and the heat sink and the heat receiving member are connected by heat transport means.

An electronic equipment is provided, which comprises a liquid-cooling system and a cooling fan as a cooling system, efficiently cools the liquid-cooling system, and reduces fan noise. The electronic equipment is provided with a liquid-cooling system, in which heat generated in a heat generating portion is transmitted to a heat radiating portion with a liquid as a medium to achieve cooling, and an air-cooling system, in which heat transmitted to the heat radiating portion is forcedly cooled, and comprises a pump that circulates the liquid between the heat generating portion and the heat radiating portion, a fan that forcedly discharges heat of the heat radiating portion to an outside, a temperature sensor that detects temperature of the heat generating portion, and storage information that beforehand prescribes the relationship between temperature of the heat generating portion and voltages of the pump and the fan, the electronic equipment being constructed such that a pump voltage is raised without changing a fan voltage when the detected temperature exceeds a first temperature, and a fan voltage is raised when temperature detected by the temperature sensor exceeds a second temperature higher than the first temperature, thus further increasing a cooling capacity.

An operation device of a tape recorder adapted to bring mechanisms such as a pinch roller, magnetic heads and so on into constant-speed tape feeding condition, making use of a part of torque of a member such as a capstan which is driven by a motor. The device has a manual operation system and an automatic actuating system. The manual operation system includes a manually operable constant-speed tape feed operation member and first locking means adapted to lock the manual operation member at an operation position to which the same has been displaced. The automatic actuating system includes a first rotary body adapted to be rotated in relation with the rotation of the shaft of the motor, a second rotary body having an engageable portion capable of performing a torque-transmitting engagement with the first rotary body and a non-engageable portion which cannot engage the first rotary body, an actuating plate adapted to be displaced by the rotation of the second rotary body and to control the position of the mechanisms, and second locking means to lock the mechanisms at a position to which they have been displaced. As the operation member is operated, it is locked at the operation position by the first locking means. A part of power for displacing the operation member to the operation position is transmitted to the second rotary body, which has confronted the first rotary body at its non-engageable portion, is slightly rotated to bring its engageable portion into engagement with the first rotary body, so as to be continuously driven by the latter. As the second rotary body is driven, it displaces the mechanisms through the actuating plate, and the mechanisms are held at the position to which they have been moved.

摘要:
Since a plurality of electric CAD systems (CAD) 1 generate circuit diagram data with different data structures, input interface (IF) software (SOFT) implements processing for extracting predetermined item data used in parts selection SOFT from each CAD, and processing for adding data obtained by the parts selection SOFT to each CAD. The parts selection SOFT implements selection of parts, output of slips, and the like on the basis of the predetermined item data. Output IF-SOFT converts information associated with the selected parts output from the parts selection SOFT into a different data format used in the subsequent process, and outputs the converted information.
