Title: Preparation of carbon fiber-based porous hollow fiber membrane
Inventor: YONEYAMA HIROAKI
IPC: D01F9/22
Filed: 1989-09-12
Abstract: PURPOSE:To make hollow fiber membrane porous, improve permeation speed, and elevate heat resistance and chemical stability of the membrane by processing an acrylic hollow fiber for carbonization treatment in an inert gas and treatment in an acidic gas after carrying out flame resistant treatment in an oxidative gas. CONSTITUTION:A hollow fiber to be used is comprised of an acrylic copolymer containing at least 90% of acrylonitrile and it is drawn to at least 3 time-length and subjected to flame resistant treatment in an oxidative gas containing O2, S, etc., at 200-300 deg.C. Then carbonization is carried out in an inert gas such as N2, Ar, He, etc., at 300-1000 deg.C. Further, treatment in atmosphere containing an acidic gas, e.g. steam, air, CO2, etc., at 600-1200 deg.C is carried out to make the membrane porous. As another method, after flame resistant treatment, treatment in atmosphere containing an acidic gas and an inert gas at 400-800 deg.C is carried out for carbonizing the membrane and making it porous simultaneously. In this way, a membrane having high gas permeation speed and high heat resistance and chemical stability is obtained.

Title: Semiconductor integrated circuit
Inventor: KATO KOJI
IPC: H03K19/003
Filed: 1990-09-05
Abstract: PURPOSE:To prevent a threshold level of an input interface circuit even when an internal power supply voltage is fluctuated by providing a threshold level compensation circuit compensating the fluctuation of the threshold level in response to the fluctuation of the internal power supply voltage of the input interface circuit to the integrated circuit. CONSTITUTION:When an output interface circuit 3 is driven and a large current flows, a voltage of an internal power supply VDD is decreased tentatively. A threshold level Vth of a circuit 1 is going to decrease similarly based on the fluctuation of the power supply voltage VDD. However, a voltage fluctuation detection circuit 6 of a threshold level compensation circuit 4 predicts the fluctuation based on an output signal from an internal circuit 2. Then the circuit 6 turns on a transistor(TR) 5. Then a voltage drop at the pull-up side in the circuit 1 is decreased by the turning-on of the TR 5 and the threshold level Vth of the circuit 1 is shifted increasingly. Thus, the shift of the threshold level Vth in the increasing direction cancels the threshold level Vth of the circuit 1 based on the fluctuation of the power supply voltage VDD to keep the threshold level Vth constant.

Title: Astigmatism correction and focusing method for charged particle optical tube
Inventor: OGASAWARA MUNEHIRO
IPC: H01J37/28
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To make a highly accurate correction for astigmatism by obtaining Fourier transformation images via the focal distances of a lens at different set values, and making the correction on the basis of the cross sectional forms of beams identified through the different focal distances. SOLUTION: Secondary particle signals are extracted through an objective lens at two different focal distances and, thereafter, two-dimensional Fourier transformation values I (kx, ky) and I' (kx, ky) are obtained for each focal distance. Thereafter, the value of R (kx, ky) determined by a relationship of differences of the magnitude of each of absolute values |I (kx, ky)|, and |I' (kx, ky)| is obtained. The direction of astigmatism is, then, obtained from the value of α, provided that the component of the value of R (kx, ky) proportional to an exponent (i2θ) or (-i2θ) for the angle θ of (kx-ky) space is expressed as Aexp (I (2θ+α) or Aexp (-i(2θ+α)) for a positive real number A and a real number α. Then, stigmata are adjusted so as to minimize the real number A.  As a result, a correction can be made, regardless of the surface shape of a sample.
