IPC: B01J19/30
Filed: 1982-12-17
Abstract: PURPOSE:To save the amount of energy by lessening the amount of circulating water by a method in which steam is directly atomized into heated air by a steam atomizer, circulating water flowing down along a wetted wall is contacted with the heated air to damp the air, and the temperature of the damped air is controlled by a plate finned coil. CONSTITUTION:Steam deprived of dust from a filter 3 is heated to a given temperature at which no supersaturation state occurs at a humidifying process by a plate finned coil 4a and then directly atomized by a steam atomizer 5. The atomized steam is once partly absorbed by circulating water flowing down on a wetted wall 11 to humidify air passing through the wet walls 11, and the other part of the steam humidifies air directly. The humidified air passes with the droplets of circulating water scatterd into air from the wetted wall device 6 through an eliminator 7, where the water droplets in the air are separated and the air is again controlled in temperature by the plate finned coil 4b and sent to a painting booth.

Abstract: PROBLEM TO BE SOLVED: To complete coverage of coating onto a wafer, by arranging supporting posts at an interval in accordance with a pattern that can have a spacing from the surface of a suscepter plate when a wafer is set on the supporting posts. SOLUTION: A suscepter 32 is a circular plate having a relatively flat upper surface 34, and a shaft is fixed at the center of the bottom surface thereof. A plurality of supporting posts 36 projecting upward from the upper surface 34 are arranged at an interval on the circumference of the circle.

Abstract: PROBLEM TO BE SOLVED: To provide a method for coating the whole surface of a bulky base material or the surface and rear surface of a base material of a plane figure with a film of the oxides and nitrides of various metals at high speed, and sputtering equipment for attaining the method. SOLUTION: Two sputtering cathodes 1A, 1B make one pair of cathodes for coating. One or more pairs of cathodes for coating are disposed in a film formation chamber where reduced-pressure atmosphere can be regulated. Voltage is applied while alternately inverting the polarity in such a way that when one of the cathodes for coating in each pair is used as a cathode the other in the pair is used as an anode and that when the other in each pair is used as a cathode the one in the pair is used as an anode. Targets which are set to the cathodes for coating can be sputtered by the resultant glow discharge. By this method, a base material, disposed practically in front of the targets stuck on the cathodes for coating in respective pairs, respectively, can be coated with a film containing the target materials as components.

Title: Production of urethane resin
Inventor: TAKAHASHI MASAHIKO
IPC: C09J175/00
Filed: 1989-08-31
Abstract: PURPOSE:To obtain a urethane resin which, when used as a hot melt adhesive, excels in initial tack and can provide high heat resistance and bonding strength by reacting an excessive polymethylene diisocyanate with a linear aliphatic polyester diol. CONSTITUTION:A urethane resin is produced by reacting a linear aliphatic saturated polyester diol (e.g. one prepared by reacting a diol derived by directly bonding OH groups to both ends of a polymethylene skeleton with a dicarboxylic acid derived by directly bonding COOH groups to both ends of a polymethylene skeleton) with a polymethylene diisocyanate (e.g. one derived by directly bonding NCO groups to both ends of a polymethylene skeleton) under conditions in which an excess of the diisocyanate is present. This resin is advantageous in that when it is used as a hot melt adhesive, the setting time is short and the initial tack is excellent as compared with a conventional urethane resin, and it has heat resistance and high bonding strength almost equivalent to those of a crosslinking-type adhesive, and especially a high adhesiveness to a plastic such as vinyl chloride resin.

Title: Clock apparatus with automatically stretchable switch
Inventor: KONO YASUSHI
IPC: G04G15/00
Filed: 1988-09-06
Abstract: PURPOSE:To obtain a clock which permits automatic fluctuation in set time by combining a micro timer and a counting operation of a sequencer. CONSTITUTION:Plants and animals sense four seasons with duration of sunshine, temperature, etc. and grow in response to them. In livestock industry, especially for poultry farmers taking eggs it is ideal to lengthen or shorten lighting time by several seconds to several minutes a day in a state as close to natural sunshine as possible. The minimum contact interval of a conventional time switch is as long as 15 minutes and setting once made is merely repeated. Therefore if it is desirable to lengthen set time by 10 minutes a day, it is necessary to set the time every three days. To eliminate this problem, lighting time is lengthened or shortened by seconds to hours a day automatically in a form nearest to the natural sunshine. This can largely improve egg productivity.
