A gas treatment apparatus for treating a gas by bringing the gas into contact with a treatment liquid. The gas treatment apparatus includes a gas-liquid contact chamber for a gas-liquid contact of the gas with the treatment liquid, a storage chamber, located over the gas-liquid contact chamber, for storing the treatment liquid, and a treatment liquid supplying unit for supplying the treatment liquid stored in the storage chamber to an inside of the gas-liquid contact chamber with a gravity-drop.

Polyisocyanate production system and gas treatment apparatus

A polyisocyanate production method that can allow effective use of hydrogen chloride produced secondarily in a polyisocyanate production process, while allowing reduction of environmental burdens, and a polyisocyanate production system for performing the polyisocyanate production method. After chlorine is allowed to react with carbon monoxide to produce carbonyl chloride in a carbonyl chloride producing reactor, the carbonyl chloride produced in the carbonyl chloride producing reactor is allowed to react with polyamine in an isocyanate producing reactor to produce polyisocyanate. Then, after hydrochloric gas produced secondarily in the isocyanate producing reactor is purified in a hydrogen chloride purifying column, the purified hydrochloric gas is oxidized in a hydrogen chloride oxidizing reactor to produce chlorine. Thereafter, the chlorine thus produced is supplied to the carbonyl chloride producing reactor from a chlorine resupply line, so that it is allowed to react with carbon monoxide to produce carbonyl chloride.

Polyisocyanate production method and polyisocyanate production system

A polyisocyanate production system is provided that can stably produce chlorine from hydrogen chloride produced secondarily while reacting stably between carbonyl chloride and polyamine and can perform an effective treatment of the hydrochloric gas produced secondarily. A hydrochloric gas control unitcontrols a flow-rate control valveto keep constant an amount of hydrogen chloride supplied from a hydrogen chloride purifying tankto a hydrogen chloride oxidation reactorvia a second hydrochloric-gas connection lineto be constant, and also controls a pressure control valvebased on an inner pressure of the hydrogen chloride purifying tankinput from a pressure sensorto discharge the hydrochloric gas from the hydrogen chloride purifying tankto the hydrogen chloride absorbing columnvia a first hydrochloric-gas connection line, so as to keep an inner pressure of the hydrogen chloride purifying tankto be constant.

A base unit accommodates a radio terminal for making radio communications. This base unit has a recess for accommodating part of the radio terminal formed at least in two mutually orthogonal planes of the base unit body. An opening is formed at the inner side of the recess. Inside the base unit, a connector electrically connects and fixes the radio terminal. A rear part of the radio terminal is inserted through the opening. The base unit includes a lid for shielding the entire recess. The base unit body may include an external antenna connected to a cable having a terminal for connecting with an external antenna terminal provided in the radio terminal. This terminal may be disposed at a position corresponding to the external antenna terminal of the radio terminal of the lid. The base unit design is improved, invasion of foreign matter is prevented, and the radio reaching distance and directivity of the base unit are enhanced.

A receiver to receive a mixture of progressive and interlace video broadcast signals without being conscious of switching between the broadcasting systems. The receiver receives the mixed video broadcast signals having different formats, converts received video signals to video signals having a different signal format from the signal format of the received video signals. The receiver simultaneously outputs the received video signals and the converted video signals. This allows the user to be unaware of any switching when the video input changes between the different broadcasting systems, by connecting a television set to either the interlace scanning system output or the progressive scanning system output of the receiver.

Receiver

A portable terminal device having: a circuit board having electronic component mounted thereon; a frame for receiving said circuit board therein; a reinforcement member in contact with the frame and for reinforcing the frame; and a cover fitted to the frame. For the device, improvement in the rigidity of the frame can prevent its breakage and resulting kinks or bends of the circuit board, and thus improve reliability of the microconnection between the electronic component and circuit board.

A video signal processing apparatus which can process video signals with different formats simply by switching between programs for processing video signals. Different system clock signals are sent to the input and output processes by employing a programmable signal processor , input synchronizing signal processor , programmable signal processor and output synchronizing pulse processor . A method for processing the video signal can be flexibly changed simply by switching between signal processing programs for programmable signal processors. In addition, the use of a memory enables the signal, which is processed using the system clock signal in the input process, to be processed using the system clock signal in the output process. The present invention thus allows the processing of video signals with many different signal formats. The design of efficient circuitry will greatly reduce costs and production processes.
