Abstract:
An air conditioner has a heat exchanger, an absorbing agent, and a controller. The absorbing agent performs an absorbing operation for absorbing moisture in passing air flowing through the heat exchanger functioning as an evaporator and a regenerating operation for desorbing moisture from passing air heated by the heat exchanger functioning as a condenser. The controller performs control such that the absorbing operation and the regenerating operation are switched at a predetermined switching time interval. The controller also performs control of a capacity of a compressor and control for changing the predetermined switching time interval such that a predetermined load out of a total heat load, which is the sum of the latent heat load and the sensible heat load, is preferentially processed.
Abstract:
A transporter is adapted to transport a sheet in a first direction. At least three detectors are disposed at a downstream side of the transporter in the first direction. Each of the detectors is operable to detect passing time of a leading end edge of the sheet. A processor is operable to calculate: a first angle of the sheet with respect to the first direction based on a first difference of the passing time detected by first two of the detectors and a first distance between the first two of the detectors; and a second angle of the sheet with respect to the first direction based on a second difference of the passing time detected by second two of the detectors and a second distance between the second two of the detectors, and operable to detect a jam in case that a value of an angular difference between the first angle and the second angle is larger than a prescribed value.

Abstract:
A hydraulic brake device for a vehicle includes an auxiliary piston having an effective cross-sectional area larger than that of a master piston, and a pressure transmitting chamber provided between the large diameter portion and the master piston. The auxiliary piston is operatively associated with the assisting operation of an assisting device. A valve mechanism hydraulically closes the pressure transmitting chamber when the actuation of the master piston is assisted by the assisting device through the auxiliary piston and establishes hydraulic communication between the pressure transmitting chamber and a reservoir of the master cylinder when the master piston is not actuated by the assisting device.
Abstract:
A hydraulic brake apparatus for a vehicle includes a hydraulic pressure generator which generates and outputs a power pressure irrespective of brake pedal operation, a regulation valve which regulates the power pressure to a predetermined pressure corresponding to the brake pedal operation force and outputs the predetermined pressure, and a master cylinder having a master cylinder pressure chamber and an auxiliary pressure chamber connectable to an output side of the regulation valve. The master cylinder is operated by auxiliary pressure in the auxiliary pressure chamber to generate a master cylinder pressure corresponding to the auxiliary pressure. A wheel brake cylinder is operated by the master cylinder pressure to apply braking force to a wheel. A pressure modulation device is disposed in a pressure passage connecting the output side of the regulation valve to the auxiliary pressure chamber to modulate the auxiliary pressure to a pressure less than the predetermined.
Abstract:
A hydraulic brake apparatus is provided for increasing a braking force with a brake feeling similar to that during a normal brake operation, even if a brake pedal is operated during an automatic brake operation. A valve device having a spool is placed in a power piston and is transferred between first and second positions depending on the operation of the brake pedal. At the first position, a power chamber is at atmospheric pressure level, while at the second position a fluid communication is established between the power chamber and an auxiliary hydraulic pressure source. The spool is driven independent of the operation of the brake pedal. When a hydraulic pressure is applied to the spool, the valve device is switched to the second position, urging the power piston to advance, without transmitting the resultant force to the brake operation member. The driving device, when applied with no hydraulic pressure, retains the valve device at the first position.
Abstract:
A hydraulic pressure assisting device includes a power piston slidably accommodated in a housing, an input member movable relative to the power piston in response to operation of a brake member, and an auxiliary hydraulic pressure source that increases brake fluid in a reservoir to a predetermined pressure and outputs power hydraulic pressure. A pressure modulator connected to the auxiliary hydraulic pressure source and the reservoir modulates power hydraulic pressure outputted from the auxiliary hydraulic pressure source to a predetermined pressure corresponding to movement of the input member relative to the power piston and supplies modulated power hydraulic pressure to a power chamber in the power piston. A cylindrical elastic member has one end portion connected to the input member or power piston and another end portion connected to the housing, with a space being defined in the elastic member connected to the pressure modulator and the reservoir.

A vehicle hydraulic brake apparatus includes a brake member, a master cylinder generating a brake hydraulic pressure by increasing the pressure of brake fluid in a reservoir, a master piston moved forward in response to operation of the brake member, a closed chamber defined behind the master piston, a power piston disposed behind the master piston, and a power chamber defined behind the power piston. An auxiliary hydraulic pressure source generates power hydraulic pressure and a pressure regulating device connects the auxiliary hydraulic pressure source with the reservoir. The power hydraulic pressure is regulated to a predetermined hydraulic pressure and is fed to the power chamber. A normally-open type valve connects the closed chamber and the power chamber, and is closable upon operation of the brake member. The closed chamber is connected to the reservoir via the normally-open type valve, the power chamber and the pressure regulating device.

A thin film transistor (TFT) which may be used as a pixel drive element in an active matrix LCD display includes a pair of side wall spacers adjacent to the opposing side walls of its gate electrode. The side wall spacers provide the gate electrode with a substantially rectangular cross section, such that the gate electrode has a substantially constant thermal conductivity over its area. The TFT has a uniform device characteristic.
