Abstract: A gas turbine includes a compressor configured to compress air; a combustor configured to mix and combust fuel and compressed air compressed by the compressor; a turbine configured to obtain rotational power using combustion gas generated by the combustor; an inlet guide vane disposed at an intake of the compressor to adjust a flow rate of air flowing into the compressor; a bleed line configured to return a part of the compressed air pressurized in the compressor to the intake of the compressor; and an on-off valve disposed in the bleed line. When the output of the gas turbine increases, a preset maximum value limit of the inlet guide vane is corrected based on a valve opening degree command value of the on-off valve and a compressor intake temperature such that the gas turbine achieves a predetermined performance.

Abstract: Provided is an air conditioner for performing heating operation through supply of a current to a heating portion including a plurality of positive temperature coefficient (PTC) heaters to be connected to a power supply section, the air conditioner including: a heater output control section for controlling an output of the heating portion; and a plurality of pulse signal generating sections provided correspondingly to the plurality of PTC heaters, each for generating a predetermined pulse signal when a corresponding one of the plurality of PTC heaters is supplied with the current, in which the plurality of PTC heaters are subjected to detection as to whether each of the PTC heaters is in a connected state or in a non-connected state based on presence/absence of the predetermined pulse signal, and the heater output control section subjects the heating portion to output control which is adjusted according to the number of the PTC heaters in the connected state.

Abstract: When cooling operation or dehumidifying operation is started, a blower fan for an evaporator and an exhaust fan for a condenser are driven at an initial rotational number. A compressor is driven at a fixed rotational number. Due to load variation, an operating current supplied from a power source is changed. When the operating current exceeds a reference value, the rotational number of the blower fan is gradually reduced. When an endothermic quantity by the evaporator decreases, a temperature of a gas refrigerant flowing through the evaporator is lowered. Since the load applied on the compressor is reduced, the operating current decreases. In this way, when the compressor is loaded, the operating current increased, however, by controlling operation of the fans as described above, it is possible to prevent that the power source is shut off due to overcurrent and operation is stopped.

Abstract: The present invention provide a substrate mounting method, a display device and a substrate for realizing sharing of the substrate without increasing the number of substrates. A substrate provided with through holes through which pins of a wire member connector are passed at an end for mounting the wire member connector and lands for mounting a board-to-board connector by soldering pins of the board-to-board connector to the vicinity of the through holes on a surface opposite to the surface on which the wire member connector is mounted, wherein the pins of the wire member connector are passed through the through holes and the pins of the wire member connector and the corresponding lands are electrically connected using conductive wires.

Abstract: Disclosed herein is a digital broadcast receiver capable of performing synthesis on a commercial that a user desires. If the commercial satisfies the Jth condition, a synthesis unit reads image data assigned to the Jth condition from a storage unit. Further, if a sync signal has been detected, the synthesis unit synthesizes an image represented by the image data read from the storage unit with video represented by a video signal outputted from a decoder, and outputs the synthesized data.

Abstract: A digital broadcasting reception device capable of accommodating a plurality of types of substrates having different mounting positions of parts in a common shielding case, having a higher degree of freedom and intended to reduce costs is provided. Inside a digital television is provided a metal shielding case wrapping around a substrate mounted with an electronic part and a detachable separation section in the shielding case. When accommodating a digital substrate having substantially the same size as that of this shielding case in the shielding case, the digital substrate is accommodated as is, and when a digital tuner mounted on the digital substrate which is smaller than this digital substrate exceeds the height of the shielding case, the digital tuner is placed at the position where the separation section is detached from the shielding case.

Abstract: To provide an electronic apparatus having a tuner circuit board that can prevent undesirable radiation, is laid out to allow a hybrid tuner designed both for digital broadcasting and analog broadcasting to be mounted. On a tuner circuit board 30 having a tuner section 130 on which a vertical-type tuner 41 and a horizontal-type tuner 42 can interchangeably mounted, an IF block 142 and an MPEG IC 140 are disposed at a distance from a power supply section 150, a grounding section 170 extending from the tuner section 130 is provided. In the case of the vertical-type tuner 41, the grounding section 170 is separated off by a tear-off line 173. In the case of the horizontal-type tuner 42, the grounding section 170 is not separated off so that the grounding section 170 reduces the effect of an undesirable radiation emitted by the mounted horizontal-type tuner 42.

A DVD recording and reproducing unit and a video cassette recording and reproducing unit are arranged in parallel with each other on a bottom face frame, wherein the DVD recording and reproducing unit is supported by supporting members so that a height of a DVD insertion portion of the DVD recording and reproducing unit becomes substantially the same as that of a video cassette insertion portion of the video cassette recording and reproducing unit.

Abstract: This invention enables setting an RF output channel to a desired channel with a simple operation. A number key on a remote controller is depressed for long time of three seconds or more as an operation other than an ordinary operation for the number key. If a control portion detects a setting signal generated by thus depressing the number key for the long time, the control portion determines whether a channel corresponding to the operated number key is vacant. If the channel is vacant, the control portion sets the channel as the RF output channel. If the channel corresponding to the depressed number key is not vacant, a vacant channel is searched. If there is a vacant channel, the vacant channel is set as the RF output channel.
