An object of the present invention is to make a housing for a ceiling-mounted type air conditioner small-sized without decreasing the performance and capacity of the air conditioner, and particularly to decrease the length of the housing in the depth direction, thereby facilitating the installation of the air conditioner and improving the room appearance. To achieve the above object, a heat exchanger is bent into a doglegged shape, the bent portion thereof is convex to the air inlet side, and the heat exchanger is inclined so as to be raised on the air inlet side. A cross flow fan rotating around a horizontal axis is disposed on the downstream side of the heat exchanger.

A work vehicle is constructed such that engine-cooling fresh ambient air is introduced from a driver's deck and then the used air after cooling is discharged forwardly of the vehicle body. The work vehicle includes an engine hood vertically pivotable about a pivot axis provided at a front portion of a vehicle body, the hood including an air outlet opening for discharging the used air after cooling, a control panel forming a rear wall of an engine room, the control panel including an air intake opening for introducing the ambient air and an instrument panel. This instrument panel is formed integrally with an upper and rear end portion of the engine hood, so that the instrument panel may be pivotably opened upwards together with the control panel.

A control device for an air conditioner operable in the heating and cooling operation mode is disclosed, which device comprises a "too hot" and a "too cold" switch which is operated by the user when he feels that it is too hot or too cold in the room conditioned by the air conditioner. When a first operation of one of these switches by the user takes place, a mode selector automatically selects the operation mode of the air conditioner, and the control of the air conditioner is started immediately. The setting or target temperature is automatically renewed every time a further operation of one of the switches is made, so that the target temperature may be adjusted to the individual preference of the user. The fan speed of the air conditioner may also be modified according to the frequency of inputs through the switches.

The invention provides a reactor to be built in a power converter. In the reactor, an induction component composed of a coil being a winding of a conductor wire, a core in which interior a magnetic path is formed and an insulation bobbin positioning and engaging a wire wound part of the coil is housed in a case to be soaked with a mold resin. Inner bottom face of the case has a plurality of surfaces having not less than two different heights letting the outside bottom of the case a reference surface, and the lower end face of the core is in contact with any of the case inner bottom surfaces excluding the lowest inner bottom surface. As a result, the reactor is suitable for on-vehicle applications to achieve reduced article variation as well as a longer service life, a shorter operation time and decreased cost.

A developing cartridge detachably mountable to an image forming apparatus main body having main body side guide portions and a cartridge mounting portion, including: a developer containing portion; a developing roller for developing a latent image formed on a photosensitive member with developer; first cartridge side guide portions provided at one end and the other end in a longitudinal direction of the roller, for engaging with the main body side guide portions to regulate a movement locus of the cartridge when the cartridge is mounted to the main body; and protruding portions provided at one end and the other end in the longitudinal direction, wherein the cartridge is mounted to the main body in a mounting direction orthogonal to the longitudinal direction with the roller being a leading edge, and the protruding portions protrude on a downstream side further than the roller in the mounting direction.
摘要:
When an ECU applies to an igniter a plurality of pulse signals, the duty ratio of which is lower than a predetermined duty ratio, as a lock release signal, a latch circuit of a lock inhibition circuit stops applying a shut-off signal to a shut-off circuit thereby to release a lock condition of an IGBT. A drive main circuit thus restarts current supply to the IGBT. A condition detection circuit outputs to the ECU a condition signal corresponding to the current supplied while the IGBT is turned on.

An electronic ballast is capable of realizing high frequency lighting of a discharge lamp and switching between at least two lighting modes with different light outputs. The ballast includes a preheating circuit having a winding component connected in parallel with a main resonant circuit with a lamp current flowing therein for the discharge lamp. A constant preheating current for the lamp filaments is supplied from a secondary winding of the winding component during lighting of the discharge lamp and a path of a current flowing on a primary winding side of the winding component is switched by a switch according to the lighting mode.
