IPC: B01D53/04
Filed: 1988-09-06
Abstract: PURPOSE: To enable the reaction of the max. output by determining the average output change of the reaction at a heat-carrying fluid temp. and the equil. temp. from a Clapeyron diagram, determining the optimum zone of the reaction by the change and effecting the reaction by setting a reference temp. at the heat-carrying fluid. CONSTITUTION: The heat-carrying fluid flows in a heat exchanger 4 in a first reactor 1 and the gas 3 produced by evaporation of the liquid in a reactor 6 enters the first reactor 1 through piping 5 and comes into contact with a solid 2 to effect the absorption reaction. When the absorption reaction ends, the inside of the reactor 1 is heated up to the equil. temp. and the desorption reaction is effected. At this time, the average output change of the reaction is determined as a function of the difference between the heat-carrying fluid temp. and the equil. temp. from the Clapeyron diagram with respect to the pressure prevailing in the reactor 1 and the optimum region of the reaction is determined. The reference temp. of the heat-carrying fluid is so set that the reaction is effected in the optimum zone.

Title: Character mixing preventive device
Inventor: BUN RIYOUCHIN
IPC: H04N5/445
Filed: 1992-08-24
Abstract: PURPOSE: To prevent the simultaneously display of the characters of a TTX data generating section and an OSD data generating section by controlling a switch section provided between the data generating sections. CONSTITUTION: When TTX information is impressed upon a TTX data generating section 10, the section 10 outputs at least one or more chrominance signals so that an F/B signal can be outputted in a high state through an output terminal O4 . Consequently, switch elements SW1 -SW4 are turned on and switch elements SW5 -SW8 are tuned off, because low voltages are impressed upon the elements SW5 -SW8 through an inverter INV. When a user impresses any kind of select signal upon an OSD generating section 20 under such a condition, OSD image signals from the section 20 are interrupted, because the switch elements SW5 -SW8 are turned off. Therefore, TTX image signals are impressed upon a matrix section 30 and R-, G-, and B-chrominance components and F/B signal are displayed on a screen in a combined state preferentially to the OSD image signals.
