Title: Analyser
Inventor: YAMADA YOSHIAKI
IPC: G01N30/88
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To easily perform the trace of sample preparation requiring a technique and to eliminate the calculation mistake on the way to obtain a highly reliable analytical value by performing the control of sample preparing procedure in an analyser together with an analytical result and reflecting the data inputted at the time of preparation at the time of the output of the analytical result. SOLUTION: At first, an eluent 1 is sent toward an injection valve 3 in a constant amt. under pressure by a pump 2. A prepared sample is injected into a passage from the injection valve 3 and sent to a column 4 to be separated at every single component. The change of the eluent is continuously measured by a detector 5 and the data thereof is sent to a data processor 6. If time is set to an axis in the data processor 6 and a signal value is plotted thereon, each component is observed as one peak. The component is quatitatively analyzed from this peak holding time. Herein, there is proportional relation between the content of each component in the injected sample and a peak area.  Therefore, by analyzing an unknown material unknown in concn. and a standard material clear in its concn., from the ratio of the peak areas of both analytical results and the preliminarily cleared concn. with the standard sample, the concn. in the unknown sample can be calculated.

IPC: G06T15/00
Filed: 1988-09-19
Abstract: PURPOSE:To describe a curve having no breaks by determining a difference step width for successive application of a recurrence formula of the forward difference method based on maximum value information of the differentiated function of a parametric cubic curve. CONSTITUTION:An optimum difference step width setting means 1 sets a difference step width most suitable for repeated operation of the recurrence formula of the forward difference method from inputted coefficients and gives the set difference step width to a recurrence formula initial value calculating means 2. This means 2 calculates the initial value of the recurrence formula of the forward difference method in accordance with the coefficients given from a parametric cubic curve generation source and the set optimum difference step width. This initial value is given to a recurrence formula executing means 3, and parameters are changed at intervals of the optimum difference step width to repeatedly execute the recurrence formula in the forward difference method. Thus, vicinity continuity between picture elements is secured with respect to an expanding picture element string, and the output free from breaks is executed.

Title: Particle board with less amount of formalin released
Inventor: MASAFUDA HAJIME
IPC: B27N3/02
Filed: 1995-08-19
Abstract: PROBLEM TO BE SOLVED: To decrease the amt. of formalin released by a method wherein chips for the surface layer are coated with a phenol resin adhesive with a pH in a specified range and chips for the core layer are coated with a methylene diphenyldiisocyanate(MDI) resin adhesive and after forming, they are molded into a sheet by heat pressing. SOLUTION: At first, wooden waste materials are ground and sifted by an ordinary means to obtain fine particle chips for the surface layer and wood piece chips for the core layer. A phenol resin with a pH of 4-9 as an adhesive for the surface layer and an MDI resin for an adhesive for the core resin are respectively applied. Thereafter, the chips for the surface layer on the bottom part, the chips for the core layer and finally, the chips for the surface layer again are formed into three layers. Then, they are heat-pressed into a sheet from both sides. As the amt. of formalin released as the adhesive is small, there exists no possibility to feel pains in eyes and throat and to feel ill caused by odor. As there exists no decrease in productivity, it is possible to manufacture it by the same method as the ordinary method for manufacturing the particle board.
