Title: Evaluating method of optical characteristics of exposure process
Inventor: HARASAKI KATSUHIKO
IPC: G03F7/26
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an evaluating method for optical characteristics of an exposure process by which the intensity distribution of light of a projected optical image can be evaluated based on a same standard without depending on the pattern shape of a photomask. SOLUTION: Projected optical images of a photomask having a pattern of fine lines and spaces and of a photomask having a pattern of fine rectangular apertures are simulated to obtain the respective distribution of the relative intensity of light. From the simulated distribution, the max. relative intensity of light and the min. relative intensity of light are obtd., from which the contrast is derived. The position coordinates differential coefft. of the relative intensity of light in the projected image of the pattern edge is calculated, which is used as a correction coefft. and multiplied with the contrast to obtain a corrected contrast CP. The defocus dependence of the corrected contrast CP is determined. From the relation thus obtd., the focus depth corresponding to the resolvable focus allowance of the photoresist in a practical photolithographic process is determined.

IPC: H04B10/2525
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To divide an optical amplifier into modules, to execute maintenance and inspection and to search trouble easily, by modularizing the optical amplifier into optical amplifiers at a pre-stage and a post-stage, and connecting the modules by optical connectors, etc. SOLUTION: A light signal transmitted to an isolator 1 is inputted to a pre-stage optical amplifier as it is and amplified. Energy for amplifying the light signal is fed from laser diodes LD1, LD2, LD3. The light signal inputted to a compensation fiber to dispersion is compensated, and inputted to a post- stage optical amplifier again from a connector 2. The light signal is branched by a BS4, and received by a PD 4. Since gains are equalized respectively on both sides of pre- and post-stages, the pre- and post-stages are manufactured separately and can be combined afterwards. Since the uniform light signal can be delivered, an interface between the preand post-stages can be conducted easily. Since the constitution of an optical amplifier for wave-length multiplexing is complicated, a modularized optical amplification section and a DCM are configured detachably of an optical connector.

Abstract: PURPOSE:To manufacture a hot-rolled steel plate stably excellent in workability even if rolling and cooling temps. fluctuate, by adding specific amounts of B, Nb, and Ti to steel and by carrying out hot rolling by regulating finishing temp. CONSTITUTION:A steel having a composition which consists of, by weight, <=0.08% C, 0.1-0.4% Mn, <0.01% Si, 0.02-0.08% acid-soluble Al, 0.005-0.020%, in total, of Nb and/or Ti, 0.0015-0.0060% B, <=0.010% N, and the balance Fe with inevitable impurities and in which B/8>N/14 is satisfied is refined. This steel is cast into a slab, which is hot-rolled at >=850 deg.C finishing temp. Since the steel of this composition has low Ar3 transformation point, finishing temp. can be lowered and rolling temp. region can be enlarged. As a result, the hot-rolled steel plate excellent in workability even if rolling conditions fluctuate can be stably manufactured in high efficiency without elevating slab- heating temp.

Filed: 1991-03-14
Abstract: PURPOSE:To detect an input signal exceeding an allowable frequency range by detecting the phase difference between the input signal of a phase comparator and the output signal from a voltage control oscillator. CONSTITUTION:A phase comparator 1 outputs the phase difference between an input signal A and the output signal from a voltage control oscillator 5, and the output signal of this comparator 1 is amplified by an amplifier 3. A loop filter 2 interrupts the frequency component of the amplified signal and outputs frequency signals according to the output signal from an oscillator 5. Here, the phase difference between the input signal of the comparator 1 and the output signal from the oscillator 5 is judged. Based on this result, a phase difference decision means 6 detects whether or not the frequency of the input signal A of the comparator 1 is within the allowable range. At this time, within the allowable range, H is outputted from a D-type flip-flop II and the input signal can accurately be judged on the output.
