Title: Production for heat exchanger
Inventor: YOKOYAMA SHOICHI
IPC: C09D183/08
Filed: 1995-01-13
Abstract: PURPOSE: To suppress a frosting phenomenon on the surface of a heat exchanger by forming a chemical adsorption monomolecular film composed of a chlorosilane surface active agent on the entire surface of the air side heat transfer face of the heat exchanger. CONSTITUTION: A fin tube type heat exchanger used for a heat pump type air conditioner is prepared, cleaned in an organic solvent, then, a material including carbon fluoride group and chlorosilane group is sprayed and applied onto the heat exchanger in a dry nitrogen atmosphere. Then, when the heat exchanger is left alone, for examle, about 30 minutes, a dehydrochloride group is produced on the surface of the heat transfer fin 1 of the fin tube type heat exchanger, since a natural oxide film is originally formed on the surface of the heat transfer fin 1 and many hydroxide groups are included in the surface of the oxide film.  Then, when the fin tube type heat exchanger is cleaned in a nonaqueous solvent and it is taken out in air, a dehydrochloric reaction with water in the air is generated so that a bridging reaction proceeds and a fluorocarbon monomolecular film 5, is formed, which is chemically bonded (covalent bond) to the surface of the heat transfer fin 1 of the fin tube type heat exchanger.

Title: Tritium recovery apparatus
Inventor: OBARA ATSUSHI
IPC: G21B1/00
Filed: 1987-01-14
Abstract: PURPOSE:To increase a transmitting amount per unit area by making a palladium membrane thin, by purging the region on the side to be transmitted of tritium, partitioned by a membrane made of palladium and a palladium alloy with gas. CONSTITUTION:The tritium gas transmitted into a Pd pipe is always purged with helium gas. Therefore, the tritium partial pressure in the Pd pipe is kept low and the same effect as the evacuation of the Pd pipe by a vacuum pump is obtained and tritium is always transmitted. Since the hydrogen occluding metal in a metal head has the absorbing activity of impurity or hydrogen but is inert to rare gas, a gaseous mixture of helium and tritium passes through the metal head and tritium is recovered in the metal head.

Abstract: PURPOSE:To make a semiconductor laser low in specified threshold current density and to enable it to output a high power by a method wherein the relation between the refractive indexes of an active layer, a first clad layer, a second clad layer, and a third clad layer is specified. CONSTITUTION:Provided that the refractive indexes of an active layer 100, first clad layers 110 and 115, second clad layers 120 and 125, and third clad layers 130 and 135 are represented by n1, n2, n3, and n4 respectively, n1, n2, n3, and n4 are so set as to satisfy formulas, n1>n3>n2, and n3>n4. When the refractive indexes are distributed as above, a photoelectrical field distribution is expanded much wider by the second clad layers 120 and 125 of high refractive index, and even if an active layer is large in thickness, a photoelectrical field distribution can be expanded to such an extent that is determined by the thickness of the second clad layers. By this setup, a photoelectrical field can be expanded to enable a semiconductor laser to output a high power keeping an active layer large in thickness and forbidden band width difference between the active layer and an adjacent clad layer large, so that carries overflow a little and a specified threshold current becomes small in density.
