Abstract: PURPOSE:To utilize effectively energy by producing differential pressure between gas components through a gas selecting permeable material and converting this differential pressure to energy easy to utilize. CONSTITUTION:An upper portion of a container 1 is constituted from a gas selecting permeable material 2 like polyimide resin film reinforced with a perforated glass for example. This container 1 is disposed in the atmosphere which makes the gas selecting permeable material 2 less permeable, and gas component GA such as permeable carbon dioxide, herium, neon, is enclosed in the container 1. this gas component GA permeates through said material 2 to produce differential pressure between the atmosphere and the interior of the container 1 to pump up water into the container 1 through a pipe with this differential pressure.

Abstract: PURPOSE: To provide a method for a controlling reproducible nonlinear optical effect with high accuracy by introducing halogen into a compd. exhibiting a cubic nonlinear optical characteristic. CONSTITUTION: Electrons are non-localized in a nonlinear optical material by the interaction of adjacent molecules and the non-local electrons contribute to the development of the nonlinear optical characteristics. The halogen molecules advance easily into the compd. and the advanced halogen intrudes into the compd. and weakens or cuts off the intermolecular interaction possessed by the material when the compd. is exposed to the vapor of the halogen. The electrons non-localized among the molecules are, therefore, localized into the single molecule and the nonlinear optical characteristic is deactivated. The advanced halogen may be removed from the inside of the compd. by heating or irradiation with laser beams, etc., insofar as the halogen is not powerfully restrained by the compd. The compd. is capable of restoring the state exhibiting the original intermolecular interaction when the advanced halogen is removed and, therefore, the nonlinear optical characteristics is restored to the original magnitude.

Abstract: PURPOSE:To obtain an information recording material free from particles, having high resolution and excellent in film forming property and workability such as smoothenability by introducing halogen molecules into a metallic complex, weakening or breaking the interaction between molecules of the complex and varying the optical characteristics of the complex. CONSTITUTION:Dimethylglyoximatoplatinum is synthesized by heating in an aq. soln. of alcohol contg. potassium chloroplatinate and dimethylglyoxime, that is, a quartz plate is fixed on a boat for vacuum deposition and a blue thin film is formed by vacuum deposition after evacuation. The light transmittance of this film is measured. The thin film of dimethylglyoximatoplatinum is then put in a laborotory dish, 0.1g iodine is further put and the dish is allowed to stand at room temp. after covering with a lid. By this operation, iodine molecules are introduced into the thin film. A solid line in the diagram shows the transmission spectrum of the thin film of dimethylglyoximatoplatinum and a dotted line shows that of the resultant thin film with introduced iodine. The transmittance is increased by introducing iodine.

Abstract: PURPOSE:To obtain such a nonlinear optical material that the nonlinear optical const. is increased, a uniform thin film can be easily obtd., thermal property of the material is stabilized in air, and the material can be easily handled, by using a plane-type complex obtd. by producing a chelate from two ligands having two C=N double bonds with the nitrogen atoms bonded to metal. CONSTITUTION:The material consists of a plane-type complex obtd. by producing a chelate from two ligands having two C=N double bonds with the nitrogen atoms bonded to metal. This plane-type org. metal complex and the production method of a thin film are not specified but any method can be used. As a typical method of the complex which is generally and preferably adopted, reaction of a compd. which acts as the ligand and a metal chloride is effected in an alcohol soln. By this method, the object plane-type org. metal complex can be obtd. The thin film is produced by vacuum vapor deposition or solvent coating method. In this case, if necessary, other material such as halogen except the ligand comp. may be added.

Abstract: PURPOSE:To obtain a useful nonlinear optical material having a high nonlinear optical effect and having no absorption in the visible region by using an org. nonlinear optical material consisting of a specified alpha-alkyl-2-furylacrylic anhydride. CONSTITUTION:This nonlinear optical material consists of an alpha-alkyl-2- furylacrylic anhydride shown by the formula and its compd. In the formula, R is lower alkyls. A strong second harmonic (green light of 1064nm) is generated when the alpha-alkyl-2-furylacrylic anhydride is irradiated with an Nd-YAG laser beam (1064nm), for example. The symmetry of crystal is lost and a nonlinear optical effect is produced from the anhydried because an alkyl substituent is present around the carbonyl group. Consequently, the anhydride is used as a useful nonlinear optical material such as the optical wavelength changing element and optical switching element.
