Title: Manufacturing device for single-crystal thin film
Inventor: KANO YASUO
IPC: C30B13/00
Filed: 1985-06-18
Abstract: PURPOSE:To detect the fused state of a semiconductor layer by a method wherein, when the semiconductor layer is fused by projecting an energy beam, the radiant light to be emitted from the semiconductor layer is imaged. CONSTITUTION:The incident angles of two beams of an energy beam (melting beam) 21 and a preheating beam 22 are respectively changed and the two beams 21 and 22 are made to incide in a lens 6 and are projected on a sample 1. As the polycrystalline silicon film, which is made its temperature rise, emits radiant light, the radiant light is enlarged by a microscope 4, is imaged by a TV camera, which is the imaging means, and is displayed on a monitoring TV 5. At this time, as laser beam having a powerful intensity also incides in the imaging means 3 (TV camera) through the microscope 4, an Ar laser beam cutting filter 32 is set in before the imaging means 3 so that the radiant light only comes into the TV camera 3. Moreover, for viewing simultaneously the pattern configuration and the part heated with the beam 22, a high-speed shutter 31, which synchronizes with the imaging means 3, is set in before the microscope 4. By this constitution, the radiant light to be emitted from the part heated with the laser beam 22 is intensified along with the temperature of the heated part, but once the part fuses, the intensity of the radiant light drops and the boundary between the solid phase part and the liquid phase part is distinctly identified.

Title: Method and device for measuring electrostatic capacitance of cylindrical dielectric sample
Inventor: MASUDA KIYOSHI
IPC: G03G5/10
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To perform a measurement with satisfactory accuracy and reproducibility by rotating a sample at a high speed, carrying a current by corona discharge, converting it into a voltage signal via a resistor, and measuring it by an A/D converter which is capable of high-speed sampling. SOLUTION: When a DC voltage signal having a fluctuating component synchronous to the rotating period of a cylindrical sample is sampled at a high speed after passed through a signal processing circuit (LPF) 4, the level of the DC component is often no longer correct, according to the form of noise in a signal through LPF 4. Therefore, the right level of the original signal is measured in advance by an A/D converter of double integrating method inferior in responsiveness to calculate the ratio with the signal level of a measuring system, and the measured level is corrected by this value in a main measurement, whereby a precise voltage measurement can be performed. Furthermore, the electrostatic capacitance of a dielectric body can be precisely measured so that the current signal can be accurately measured.  The DC voltage signal, having fluctuating components can be precisely sampled and measured by utilizing the A/D converter of double integration system at a high speed.

Abstract: PURPOSE:To try not to disturb an air flow at the upper part of an aseismatic foundation structure by sucking indoor air into a chamber under the floor by means of a suction fan connected to the hollow part of the stage for an aseismatic foundation structure via through holes and hollow part. CONSTITUTION:Clean air is blown off into a chamber 20 via a high performance filter 16 of a ceiling chamber 12, and passes through a grating 32 on the floor surface in the form of a down flow and is sucked into a chamber 34 for the stage 54 for the aseismatic foundation. In this case, air at the upper part of the aseismatic foundation 50 passes through a hollow part 56 from a through hole 58 of the stage 54 for the aseismatic foundation, and is sucked into the chamber 34 under the floor. There is almost no possibility that clean air within the chamber 20 in the form of a laminar flow might be disturbed at the upper part and around the periphery of the aseismatic foundation, and a substantially constant down flow is obtained. Thus, there is almost no possibility that an air stagnation zone might be produced. Further, the operator can easily approach a device 52 by riding on the stage 24, and further can operate without affording any vibration to the aseismatic foundation.
