Title: Circle plotting device using electron or ion beam
Inventor: HAYASHI KUNIHITO
IPC: G21K5/04
Filed: 1995-03-30
Abstract: PURPOSE: To facilitate fine adjustment of the angular velocity for plotting a circle at high speed, without adjusting clock cycle, by providing an angle voltage generator with a variable window limit type up-and-down counter, a D/A converter, a variable amplifier, and a control circuit. CONSTITUTION: In a variable window limit type up-and-down counter 11, the upper and lower limits of a window are variably set by means of a control circuit 14. For example, a square wave 51 output with normal eight clocks 50 is output as a square wave 61 with four clocks 60 that are half the eight clocks 50. The square wave 61 is converted into an analog angle voltage 62 by a D/A converter 21 and then amplified by a variable amplifier 13 into linear form of the same magnitude as an output angle voltage 53 which is predetermined according to the size of a circumference. The amplification factor of the amplifier 13 is varied by the circuit 14 in synchronism with the variation rate of the window limits of the counter 11, and even in the same period of scanning clocks the same output angle voltage 63 can be obtained in the half time.  Such a voltage is input to generators for cosine and sine waves, and a circle of desired size is plotted.

Title: Manufacture of water-containing arginic acid film
Inventor: YONETO KUNIO
IPC: A61K9/70
Filed: 1989-04-14
Abstract: PURPOSE:To enable easy continuous manufacture having no dispersion of effective components by forming a film of a soluble arginic salt aqueous solution, spraying a soluble calcium salt aqueous solution to this film, and gelling the film of said aqueous solution, and forming a gelled film. CONSTITUTION:An arginic acid salt is dissolved in water to form an aqueous solution. This solution is adjusted to have a viscosity within the range of several hundreds to several ten thousands cps so that a film can be formed by general coating method. Separately to this, an aqueous solution of soluble calcium salt is prepared. This is adjusted in such a manner that the quantity of the contained calcium ion is preferably 0.2 to 0.35 moles per mole of Na ion contained in the sodium arginate aqueous solution. The concentration of the soluble calcium salt aqueous solution is preferably 1 to 20wt.%. Then the soluble arginate aqueous solution is spread on a base film to form a film, to which the soluble calcium salt aqueous solution is sprayed. Gelling occurs simultaneously with spraying, so that the water-containing arginic film can be continuously produced at high efficiency.
