摘要:
A communication device which efficiently dissipates locally generated heat, and at the same time is small in size and light in weight, is provided. A high-efficiency heat-dissipating fin section having fins disposed on an heat pipe which is bent into an S shape is mounted on a high-temperature heat-generating section that generates high-temperature heat. A heat-dissipating fin section having fins disposed on a heat-receiving plate thereof is mounted on a low-temperature heat-generating section that generates heat having a lower temperature than that of the high-temperature heat generated by the high-temperature heat-generating section. This makes it possible to efficiently dissipate heat and reduce the size and weight of the communication device.

A transmitting and amplifying unit for a wireless communication device. The transmitting and amplifying unit includes a C-shaped frame having an upper plate having a first cutout, a lower plate having a second cutout aligned with the first cutout, and a side plate connecting the upper plate and the lower plate; a main amplifier unit fixed to the lower plate and having a concentrated heating portion; and a subamplifier unit fixed to the upper plate. The transmitting and amplifying unit further includes a radiating fin unit mounted on the concentrated heating portion of the main amplifier unit and extending upward through the first cutout of the lower plate and the second cutout of the upper plate. The radiating fin unit has an upper end fixed to the subamplifier unit. The transmitting and amplifying unit further includes a cooling fan fixed to the C-shaped frame, and a printed wiring board mounted on the C-shaped frame so as to face the side plate, whereby a duct is formed between the C-shaped frame and the printed wiring board.

A voltage monitoring circuit includes a plurality of voltage input terminals which input a voltage across each of a plurality of series-coupled battery cells, a selection circuit which, by selecting two of the voltage input terminals, selects a voltage across one of the battery cells; an A/D converter which converts the voltage across the battery cell into a digital value, a control unit which sends the digital value to an external controller, a ground wiring which is coupled to a ground terminal for inputting a ground level voltage for the voltage monitoring circuit, the ground terminal being among the voltage input terminals, and through which the voltage monitoring circuit is supplied with the ground level voltage, a terminal which is supplied with a lowest fixed potential, and a switch circuit which is coupled between the first terminal and the ground wiring.
摘要:
An endoscope main body constituting an endoscope in a state in which an elongated detachable observation optical system is attached to the endoscope main body, and in a proximal end of an insertion section of the endoscope main body, a branch member is disposed. The branch member is provided so that a first extended section and a second extended section are branched from each other and thereby first and second operating sections are separately arranged. Furthermore, the branch member has an opening as an inlet which guides an imaging module in a distal end of the observation optical system to a hard portion of the insertion section.
摘要:
In a level conversion circuit mounted in an integrated circuit device using a plurality of high- and low-voltage power supplies, the input to the differential inputs are provided. In a level-down circuit, MOS transistors that are not supplied with 3.3 V between the gate and drain and between the gate and source use a thin oxide layer. In a level-up circuit, a logic operation function is provided.
