Title: Method and apparatus for dissipating volatile chemical
Inventor: SAITO HACHIRO
IPC: A61L9/12
Filed: 1989-03-28
Abstract: PURPOSE:To enable a composition of dissipating gas from volatile chemicals to be controlled almost constant by fractionating volatile chemicals composed of multicomponent liquid or solid into two ro more component groups of different volatility and by making these component groups dissipate from respective small chambers so as to dissipate a gas having almost the same composition as those volatile chemicals as a whole. CONSTITUTION:A container 1A is made of a suitable chemical-impermeable material such as plastics, metal, glass or ceramics and its shape is not specified. The container 1A has small chambers 4, 4', which are separated with each other by a partition wall 2. Two or more chemical, component groups A and B, which are fractionated based on a difference in volatility, are stored in the small chambers 4 and 4' respectively. Rates of dissipation of the chemical components from the small chambers 4 and 4' are regulated by arranging membranes 3 and 3', which have different permeabilities for the chemicals, on the tops of respective chambers. Among the chemical components, a highly volatile component or component group is made to dissipate through a low permeable film and a low volatile component or component groups through a highly permeable film. It is possible, by using this method, to keep a composition of gas dissipating from the volatile chemicals almost constant for a long time.

Title: Bezier curve drawing system
Inventor: KASAHARA TATSUO
IPC: G06T11/20
Filed: 1990-03-26
Abstract: PURPOSE:To draw a satisfactorily smooth Bezier curve with the small arithmetic value and at a high speed by using a modified formula where the fixed value part of the Bezier curve is increased. CONSTITUTION:A modified formula B(t) = ((alpha1t + alpha2) t + alpha3) t + alpha4 is used as an arithmetic formula for the coordinates of a point of a Bezier curve. Where, Z12 = 3(Z1 - Z2), Z1a = 3(Z1 - A), alpha1 = E - A + Z12, alpha2 = -(Z1a + Z12), alpha3 = Z1a, and alpha4 = A. When the Bezier curve is drawn, alpha1 - alpha4 are previously calculated and stored. Based on this calculated value (fixed value), a calculation point (t) is computed for each DELTAt in a Bezier section 0<=t<=1. Thus the coordinates B(t) of a point of the curve is obtained. In such a way, the fixed value part of an operation is increased with use of a modified formula. Thus it is possible to reduce the arithmetic quantity and to draw a satisfactorily smooth Bezier curve at a high speed.
