Title: Antimutagenic agent
Inventor: SUWA YOSHIHIDE
IPC: A61P43/00
Filed: 1983-05-30
Abstract: PURPOSE:An antimutagenic agent containing lipoic acid as an active constituent, and capable of inactivating the mutagenicity caused by reaction of vitamin C with table luxuries. CONSTITUTION:An antimutagenic agent containing lipoic acid as an active constituent. A therapy taking in a large amount of vitamin C has been increased, but the vitamin C has strong reducing property due to the enediol groups in the molecule thereof and further useful physiological activity and possibility of causing toxic reaction depending on the kind of coexisting substances. In fact, if the vitamin C is dissolved with coffee, mutagenicity of about 6 times that of the coffee is produced. Lipoic acid has been used as a remedy for hepatocirrhosis or hepatic lethargy, etc. but is capable of reducing the mutagenicity of food increasing to 6-10 times by reaction of the vitamin C with table luxuries or copper ions. Thus, the above-mentioned agent is expected to be used effectively also in medical fields for preventing carcinogenicity.

Title: Production of trifluoroacetic acid
Inventor: GOTOU ISAO
IPC: C07C51/00
Filed: 1984-05-15
Abstract: PURPOSE:Trifluoroacetyl chloride is brought into contact with water-containing trifluoroacetic acid to consume the water for hydrolysis of the chloride whereby trifluoroacetic acid substantially free from water is obtained. CONSTITUTION:In the production of trifluoroacetic acid substantially free from water by effective hydrolysis of trifluoroacetyl chloride, the hydrolysis is carried out in the following A and B stages: A, by bringing trifluoroacetic chloride into contact with water-containing trifluoroacetic acid to form substantially water- free trifluoroacetic acid and B: by allowing trifluoroacetyl chloride to react with an excessive amount of water into trifluoroacetic acid, which is used in the A stage. Since the hydrolysis of trifluoroacetyl chloride is more delayed, as the amount of water is more reduced, these processes are preferably operated as a continuous circulation.

IPC: A47J27/00
Filed: 1991-04-25
Abstract: PURPOSE:To suppress a dewing generated on the inside surface of a cover body at the time of rice cooking by a simple circuit configuration. CONSTITUTION:At the time of rice cooking, a rice cooking heater 36 is energized and deenergized by opening and closing a relay 74, and also, a barrel heater 37 and a cover heater 38 are energized by turning on a triode AC switch 75. At the time of warming, the rice cooking heater 36 is always deenergized by opening the relay 74, and also, the barrel heater 37 and the cover heater 38 is energized and deenergized by turning on and off the triode AC switch 75. In the course of rice cooling, the cover heater 38 heats the cover body, and dewing on its inside surface is prevented. Since the rice cooking heater 36 is not energized at the time of warming, it is unnecessary to add one triode AC switch for the circuit configuration, and the circuit configuration becomes simple.

Title: Plate-shaped electrostatic recording medium
Inventor: TAMURA SAKAE
IPC: G03G5/02
Filed: 1979-07-30
Abstract: PURPOSE: To facilitate record write, erasure and recording by using a plate-shaped electrostatic recording medium equipped with a plane-shaped conductive base body, a dielectric coating provided to the surface of said base body and a contact-preventive projection part on said surface.  
     CONSTITUTION: The plate-shaped electrostatic recording medium consists of dielectric coating 1, plate-shaped conductive base body 2 and contact-preventing projection part 3 formed in the same body with the conductive base body. Such a constitution is effective when the plate-shaped electrostatic recording media are held being stacked.

Title: Nonlinear optical material
IPC: G02F1/361
Filed: 1992-03-24
Abstract: PURPOSE:To enhance three-dimensional nonlinearity, to prevent occurrence of thermal and optical damage due to laser beams and to improve solubility in the material to be used by incorporating a specified compound prepared by conbining a pi electron-conjugated type dyestuff with helicene (Z) having a vinylene group in it. CONSTITUTION:This nonlinear optical material contains the compound prepared by combining the pi electron-conjugated type dye stuff with the helicene (Z) having the vinylene group in it represented by the formula Z-CH=CH-D. It is preferred that the helicene Z is optically active in order to apply various signal processing methods especially for reading out the change of the refractive index. The compound of this formula is enhanced in nonlinearity by nonloclized pielectrons enlarged by the vinylene group (-CH=CH-) and the pi electron- conjugated dye D. On the other hand, since the spiral electron system of the helicene combines with the straight chain pi electron system, intermolecular interaction does not become too great and its solubility in solvents is not lowered, and accordingly, its synthesis and manufacture of a device by using it is made easy.
