IPC: G05B13/04
Filed: 1989-05-12
Abstract: PURPOSE:To obtain desired speed controllability, speediness, response, etc., by varying the transfer function of a driving device equivalently into a given transfer function. CONSTITUTION:A desired transfer function G(S)0 and its reciprocal 1/G(S)0 are prepared for the control part CNT of the driving device which has a trans fer function G(S). Then the sum of a control command signal U and the output of the transfer function 1/G(S)0 is used as an input (u) to the function G(S) and this input (u) is supplied even to the function G(S)0. Then the difference y-Y between the output Y of the function G(S) and the output (y) of the func tion G(S)0 is inputted to the function 1/G(S)0. Thus, the given transfer function is given desired characteristics to obtain desired output characteristics of the driving device.

Title: Method for stabilizing n-vinylamide
Inventor: SATO SHINICHI
IPC: C07C233/09
Filed: 1995-05-18
Abstract: PURPOSE:To reduce a loss due to polymerization, decomposition, etc., and enhance the stability of N-vinylamide by adding quinones or alkali-modified substances thereof to the N-vinylamide and distilling the resultant mixture. CONSTITUTION:This method for stabilizing N-vinylamide (e.g. N-vinylformamide) is to add quinones (e.g. p-benzoquinone) or alkali-modified substances thereof in an amount of 50-10000ppm expressed in terms of the quinones thereto and distill the resultant mixture. The alkali-modified substances of the quinones are produced by dissolving the quinones in a solvent such as methanol and adding a small amount of caustic soda or caustic potash thereto. Since the alkali-modified substances are nonvolatile and can readily be removed from the N-vinylamide by the distillation, they are suitably used for the stabilization. Thereby, the stability in storage and transportation is enhanced.

IPC: B03C3/38
Filed: 1989-05-16
Abstract: PURPOSE:To allow measurement with high accuracy even if the sizes of particles are fine and to allow the execution of sepn., classification or surface reforming and control with high efficiency by charging the fine particles after previously growing the fine particles to large grain sizes. CONSTITUTION:The fine particles in gas 1 are charged by the photoelectrons generated when a photoelectron releasing material 3 (e.g. Fe, Cu, Al) is irradiated with the UV rays from a UV lamp 2 and/or radiations in the electric field formed between the photoelectron releasing material 3 and electrodes 4. A condensable material (e.g. alcohol) is condensed on the fine particles to largely grow the grains sizes of the fine particles in a grain size growing section 6 and thereafter, the fine particles are charged at this time. As a result, the measurement with the high accuracy is executed even when the sizes of particles are fine. The sepn., classification or surface reforming and control are thus executed with the high efficiency.
