An apparatus for continuously granulating powder material has a feeder for continuously supplying powder material, and a granulation vessel. The granulation vessel includes a granulation zone and a drying zone. The apparatus also has a spray nozzle disposed so as to be declined above the granulation zone for adding binder to the powder material, a perforated plate disposed below the granulation zone and the trying zone, an intermediate weir disposed between the granulation zone and the drying zone so as to provide a space between the intermediate weir and the perforated plate, an outlet weir disposed at an outlet side of the drying zone, and a heated air supplying device for supplying from below heated air to the granulation zone and the drying zone so as to form a fluidized bed of the material.

A data transmission apparatus is disclosed which is of the type in which data generated therein by two data generating blocks are transmitted through a bus common to these blocks. One data generating block generates a data validating signal which indicates that the data to be transmitted thereby is valid and delivers the data to a bus, while the other data generating block is inhibited from outputting its data when the data validating signal exists.

A refrigeration apparatus has a refrigerant circuit which is constituted by a compressor, a condenser, a first pressure reducer, a gas-liquid separator, a second pressure reducer and an evaporator connected to one another in series. The refrigeration apparatus also has a gas injection line connected between a gaseous phase portion of the gas-liquid separator and a compression chamber of the compressor. The improvement comprises a liquid refrigerant extracting passage providing a communication between a portion of the gas-liquid separator at a predetermined level and a portion of the low-pressure side of the refrigerant circuit. With this arrangement, it is possible to stabilize the level of the liquid refrigerant in the gas-liquid separator.

An illuminance sensor detects an illuminance value for an environment in which a display device is placed and provides the illuminance value to a controller. The controller determines whether to cause the display device to make a transition to a power saving mode or not in accordance with the illuminance value inputted thereto. For the transition to the power saving mode, the controller stops the operation of a backlight drive signal generator to turn off a backlight unit, and stops the supply of power and a display signal to a liquid crystal panel.

An image display apparatus is provided that enables the chromaticity of a display screen of a display apparatus to be adjusted to the chromaticity desired by a user. The image display apparatus is formed by a backlight unit that is provided with a plurality of light sources and by an image display panel that is placed at a front surface of the backlight unit. The image display apparatus performs a monochrome display. In the image display apparatus, the light sources have at least three different types of luminescent colors that surround a target color on a chromaticity diagram.

Discriminator receiving a DDC transmission request from an external computer through a DDC control, judges whether a video signal inputted from the computer is a signal of analog specification or digital specification from an analog channel input detection signal from an analog synchronizing signal detector. On the basis of the judgment result, the discriminator controls the DDC control, input channel switch and OSD switch to switch EDID data, an input channel and OSD into ones supporting the specification of the video signal, respectively. In a display monitor having a DDC function which includes a DVI-I connector, with the above constitution, a correct setting of the input channel, EDID data and the like is automatically made in accordance with the specification of the input signal.

A liquid crystal display device for image display realizing clear and optimum image display by comprising a brightness detector for detecting brightness of image signal after digital conversion and a voltage dividing circuit for outputting the reference voltage in the level depending on the detected value in view of adjusting contrast of display screen by judging brightness of image signal and controlling the reference voltage.
摘要:
A refrigeration system suitable for use in an air conditioner has a main refrigerant circuit including a compressor, a condenser, a first pressure reducer, a gas-liquid separator, a second pressure reducer and an evaporator connected in series to form a closed loop, and a gas injection passage providing a communication between the gaseous phase part of the gas-liquid separator and a compression chamber of the compressor. A stop valve is disposed in the inlet and outlet pipes of the gas-liquid separator, and a bypass passage is provided for connecting directly the outlet pipe of the condenser to the inlet pipe of the evaporator to bypass the gas-liquid separator. The stop valve is adapted to be controlled such that, when the gas injection to the compressor through the gas injection passage is not conducted, the refrigerant flows through the bypass passage bypassing the gas-liquid separator, while the gas-liquid separator functions as a receiver for adjusting the amount of refrigerant circulated in the main refrigerant circuit.
摘要:
In an air conditioner separated into an indoor unit and an outdoor unit, a control circuit comprises a three-phase power source connected in common to the indoor and outdoor units, and a signal line led out from two phases of the power source. A contact of an electromagnetic relay energizing a compressor of the air conditioner is connected on the portion of the signal line in the indoor unit in series with a current sensor sensing the current flowing through the signal line, and a contact of a protective relay protecting the compressor is connected on the portion of the signal line in the outdoor unit in series with the electromagnetic relay. A first controller is disposed in the indoor unit for controlling on-off of the relay contact of the electromagnetic relay, and a second controller is disposed in the outdoor unit for energizing the protective relay contact thereby controlling on-off of the compressor.
