Title: Production of cyclic polyacrylonitrile structure
Inventor: YAMAGUCHI YUTAKA
IPC: D06M101/16
Filed: 1985-11-13
Abstract: PURPOSE:To obtain a cyclic polyacrylonitrile structure useful in the production of carbon fiber inexpensively, by treating an acrylonitrile polymer with an aqueous solution containing cuprous ions. CONSTITUTION:A cyclic polyacrylonitrile structure is produced by treating an acrylonitrile polymer with an aqueous solution containing cuprous ions. According to this process, polyacrylonitrile as a starting material can be converted into a cyclic polyacrylonitrile structure without being blackened by the catalytic action of cuprous ions. It is necessary that the cuprous chloride concentration in a catalyst bath is 0.2% or above, but it is not necessary that it is 2% or above. When the concentration in the catalyst bath is below 0.2%, the aim can not be achieved because of an extremely low catalytic action of cuprous ions on polyacrylonitrile. When it is above 2%, the effect can no longer be increased, so that a further increase in the amount of addition is meaningless.

Furthermore, when the control section 4 detects a one-line coded end signal, a coded scanning line counter 8 is counted up and the coded line number is counted. Then the count of the counter 9 and the block generation code data bit number specified in advance by taking a memory capacity at a receiver side into account are compared and when they are equal to each other or the count exceeds the specified bit number, data generation by one block is finished. When the receiver side detects the full white level line, the motor is driven at a speed by a multiple of (m) of the usual speed.

Title: Patterning of concrete columnar member
Inventor: TOMIUCHI SHINICHI
IPC: C04B40/00
Filed: 1994-10-24
Abstract: PURPOSE: To pattern the whole of a concrete columnar member inclusive of the thick-walled interior thereof by kneading concrete having fibers different in length compounded therewith in different amts. and imperfectly mixing this concrete to cast the same into a centrifugal molding machine to perform molding. CONSTITUTION: A concrete product such as a Hume concrete pipe, a utility pole or a columnar gatepost is produced by kneading concrete having fibers different in length compounded therewith in different amts. and imperfectly mixing this concrete to cast the same into a centrifugal molding machine to perform molding. Since concrete is set to an imperfectly mixed state, a state such that partially different various fibers are dispersed is obtained and, by performing centrifugal molding in this state, various fibers are continuously mixed to impart patterns to a concrete columnar member. These patterns are adjusted by controlling the mixed state such as the mixing ratio or mixing time of concrete.

Title: Core type transformer core
Inventor: HAMADATE YOSHIO
IPC: H01F27/245
Filed: 1984-12-07
Abstract: PURPOSE:To obtain a transformer core which has an excellent magnetic characteristic and can be made small-sized and lightweight, by providing a construction in which one side of the V-shape is longer than the other so that the apexes of the T-joint portion of the leg cores opposed to the side leg cores are biased to the sides opposite to the side leg cores. CONSTITUTION:A three-phase, five-leg core is provided with a construction in which only the central leg core 10 around which a winding is wound has plates 10a, 10b combined so that the sides of the V-shape are substantially equal in length, and the other leg cores 20, 30 have iron plates having widths l1-l4 combined so that the apexes of the V-shapes are biased to the central leg core 10 side. With this structure, magnetic flux sharing rate can be uniformized in the respective portions in the yoke, so that a core having an excellent magnetic characteristic can be obtained, and an outstanding effect can also be expected for making it small-sized and lightweight. Since the central leg core 10 and leg cores 20, 30 are all constructed with two pairs of iron plates which wire cut slantwise, scrap is completely prevented from being produced by cutting them out from a steel tape which was previously slit at a predetermined width.

Title: Injection foam molding method
Inventor: KONDO HIROAKI
IPC: B29L31/50
Filed: 1993-09-20
Abstract: PURPOSE:To obtain a foam cell having a desired size in proper magnification by controlling the mold opening speed while the space between molds is expanded so as to change the same stepwise from a high speed after the start of mold opening to a low speed before the completion of mold opening. CONSTITUTION:Molds A, B are respectively fixed to a fixed plate 1 and a movable plate 2 to form a space D. When a resin containing a foaming agent is injected into the space D, the distance between the molds A, B is increased by a stroke l and the space D is expanded so as to permit foaming. The expanding speed of the space D is set by the control of a mold opening speed controller 13 to a hydraulic unit 11 with respect to a cylinder device 3. The expanding speed is controlled so as to be high at the time of mold opening and made low before the completion of mold opening. By this constitution, foaming magnification is increased at the time of the start of mold opening and the close contact degree of a skin layer to the surfaces of the molds due to foaming force is enhanced in such a state foaming force before the completion of molding opening is low to improve the surface state of a molded product. Therefore, the molded product having a soft surface feeling is obtained.
