Title: Method of controlling drying temperature of photographic film
Inventor: KAMEOKA KIMITAKA
IPC: G03D15/02
Filed: 1988-03-18
Abstract: PURPOSE:To maintain the size of a photographic film after drying at the size at the time of exposing by controlling the inside of a drying chamber to the optimum drying state temp. or below at which the moisture content of the photographic film does not change when the photographic film right after emission from the drying chamber is rested in working environment. CONSTITUTION:The photographic film has the moisture content in nearly equal. with the humidity in the working environment in case of subjecting the photographic film to the exposing. The photographic film elongates by absorbing moisture when this photographic film is subjected to development processing, etc. The emulsion layers and backing layer attain the elongated state at the time of the drying when the film is dried at the temp. above the optimum drying temp. but the emulsion layers and backing layer are not elongated in the drying chamber and, therefore, the elastic force of both the layers is not lost when the film is dried at the optimum drying temp. The photographic film is thus restored to the size at the time of the exposing by the elastic force and the generation of a dimensional error in the film at the time of the exposing and at the time of the drying is obviated. The optimum dry state is thereby obtd.

Title: Nonionic surfactant and its production
Inventor: NAKAMURA YOSHINOBU
IPC: C09K23/38
Filed: 1994-03-11
Abstract: PURPOSE:To obtain an ethylene oxide non-addition type nonionic surfactant low in toxicity and skin irritancy having a usage of washing or emulsification by reacting a primary or a secondary alkylamine with ascorbic acid. CONSTITUTION:Primary amine such as octylamine or decylamine or secondary amine such as laurylmonomethylamine or mirystylmonomethylamine are reacted with ascorbic acid to perform ring opening amidation reaction. This reaction is advanced while reactants are mixed and stirred under heating, and pref., under pressure of inert gas. By this method, a nonionic surfactant represented by the formula (wherein R1 is a 8-22C alkyl group and R2 is hydrogen atom or methyl group) is obtained. Since this nonionic surfactant is low in toxity nd skin irritancy, it has a wide usage as a emulsifier or a detergent.

Title: Casting mold, production thereof and cast molding method
Inventor: FUJIYOSHI HAJIME
IPC: B28B1/26
Filed: 1993-03-25
Abstract: PURPOSE:To prevent the formation of voids or stripes in a molded product. CONSTITUTION:A pair of upper and lower molds 51, 52 are formed from a water permeable material and a casting port forming part 56 formed from a water impermeable material (fluoroplastic) having good releasability is upwardly embedded in the lower mold 52 to be fixed thereto. A casting port 54 and the seal part 55 provided to the periphery of the casting port 54 are integrally formed to the casting port forming part 56. The seal part 55 has the function suppressing the dehydration action (the accumulation action of a raw material) in the peripheral part of the casting port 54 at the time of cast molding and preventing the closure of the casting port 54 up to the time just before the completion of cast molding. However, since the seal part 55 is integrally formed to the casting port forming part 56 embedded in and fixed to the lower mold 52, the seal part 55 becomes hard to release (in other words, releasability is improved) and the life of the seal part 55 is drastically extended.

Title: Production of metallic powder
Inventor: OGAWA KATSUMI
IPC: B22F9/08
Filed: 1986-03-25
Abstract: PURPOSE:To efficiently utilize injection energy and to prevent the generation of blockage by forming the odd-numbered pieces of atomizing jets as equal intervals or varying the injection angle of depression on the opposite sides of the atomizing jets formed at equal intervals. CONSTITUTION:The odd-numbered pieces of the atomizing jets are formed at equal intervals so that the injection positions do not exist in the positions opposite 180 deg. from each other with the axial center of the falling column M of a molten metal as a center. The even numbered pieces of the atomizing jets are otherwise formed at equal intervals and the injection angle of depression from the opposite sides is varied. For example, the device is so arranged that the jet (a) is made incident on the circle B and the jet (e) in the opposite position is made incident on the circle A to vary incident angles of both the jets with the falling column M of the molten metal. The offsetting of the injection energy and the generation of the blockage are averted and the metallic powder is stably produced by the above-mentioned method.

Abstract: PURPOSE:To suppress the spreading angle of an exit beam to a lower angle by parting the light exit end face of an optical waveguide from a substrate end face, then forming the part of the optical waveguide adjacent to the light exit end face thicker than the other part of the optical waveguide. CONSTITUTION:The light exit end face 11b of the optical waveguide 11 formed on the transparent substrate 16 is positioned apart from the end face 16a of the substrate 16 toward the inner side and the part adjacent to this light exit end face 11b is formed thicker than the other part 11 of the optical waveguide. The laser beam 13 emitted from the light incident end face of the optical waveguide 11 into the optical waveguide progresses in the optical waveguide 11, is emitted once from the light exit end face 11b to the part of the substrate 16 and is emitted from the substrate end face 16a to the outside of the substrate 16. The spreading angle phi3 the light beam 13B to be emitted at this time decreases as the spreading is suppressed and, therefore, the use of an inexpensive cylindrical lens 25 having a smaller aperture diameter is possible. The light intensity distribution in the spreading angle phi3 can be the distribution approximate to a Gauss distribution.

Title: Character information transmission system
Inventor: HIRASAWA KAZUO
IPC: H04L23/00
Filed: 1985-03-30
Abstract: PURPOSE:To attain accurate and efficient character transmission by displaying a recovered text which is obtained by reading an external character of picture pattern corresponding to a location where external character display information of a received text is inserted from a memory and inserting the result. CONSTITUTION:When the reception of a text is finished, a control section 9 reads character information stored in a character storage section 71 in the order of reception so as to discriminate whether or not the information is an external character display symbol. When the information is not the external character display symbol, the information is outputted and displayed on a display section 8 as it is, and when the information is the external character display symbol, a corresponding external character pattern is read from a pattern storage section 72 in response to a number added to the external character display symbol, outputted to the display section 8, where the pattern is displayed. Since a received text is reproduced by replacing the external character picture pattern into a location where the external character display symbol in the text is inserted at the reception terminal device R, the terminal device R displays the external character as the font. Thus, the transmission efficiency of text is improved and an accurate reception text is obtained.

Abstract: PURPOSE:To attain optimum transmission by storing an optimum transmission parameter at each opposite terminal equipment into a memory section in the transmission with an opposite terminal equipment and sending the data based thereupon. CONSTITUTION:When abbreviated dial data is inputted in the transmission operation routine, a controller section 3 decodes it to read a transmission parameter stored in the address of a corresponding memory section 2.

Then the controller section 3 reads a full dial data from the address of the memory section 2 corresponding to the abbreviated dial data to control a line control section 5 based thereupon thereby sending the dial signal and the routine is restored to the transmission operation routine. As a result, the facsimile transmission with the opposite terminal equipment by the optimum transmission parameter is executed.
