Title: Surface deffct inspecting device
Inventor: TSUJI NOBUHIKO
IPC: G01N21/892
Filed: 1978-03-08
Abstract: PURPOSE:To detect surface defect at high precision without using expensive optical device, by  disposing plural photoelectric elements across the reflected diffracted light of coherent light such  as laser beam. CONSTITUTION:Photoelectric transducers 31, 32 of array form are disposed opposedly across  the principal relfected light of reflected light 10 of laser beam 8 entering the object being inspected 4. The length of transducers 31, 32 should be more than the width of object being inspected  4, and the transducers are located at equal distance from the point of reflection, being parallel  to a scanning locus 9. The laser beam 8 emitted from a laser beam source 1 is reflected by a rotating mirror 2 and a stationary mirror 3 to enter the surface 4a of the object being inspected,  and draws a scanning locus 9 due to the rotation of the rotating mirror 2. The laser beam thus  entering the surface is scattered and diffracted variously depending on the surface conditions,  and its reflected light 10 contains the surface information. Since the transducers 31, 32 are disposed on both sides of the principal reflected light of the principal reflected light 10, only the  light corresponding to the diffraction pattern 23 caused by flow or defect may be detected by  the transducers 31, 32. The outputs of transducers 31, 32 are processed in a signal processing part 33, and flaw signal is outputted.

Title: Apparatus and method for measuring double refraction
Inventor: MIURA AKIHISA
IPC: G11B11/10
Filed: 1989-02-03
Abstract: PURPOSE:To make it possible to measure a double refraction value in a short time highly accurately by inserting a double refraction member between a first polarizing plate and a second polarizing plate which are provided in such a way that the polarizing directions of the plates are orthogonally intersected, and measuring the amount of light after the transmission through the second polarizing plate. CONSTITUTION:In a double refraction measuring apparatus 10, a double refraction member 4 can be inserted between a first polarizing plate 1 and a second polarizing plate 2 which are set at a pattern wherein the polarizing directions are orthogonally intersected. Collimated light rays which are emitted from a laser diode train 11 are vertically inputted into the second polarizing plate 2 from the first polarizing plate 1. The amount of the light rays after the light rays have been transmitted through the second polarizing plate 2 can be measured with photoelectric transducer element train 12. The correlation between the measured value of the amount of light and the double refraction value in the optical system that is composed of the polarizing plates 1 and 2, the diode train 11 and the element line 12 is determined by using a double refraction member whose double refraction value is known beforehand. When the double refraction member 4 as an object to be measured is inserted and the amount of leaking light which has been transmitted through the polarizing plate 2 is measured, the double refraction value can be obtained.

Title: Metallic vapor discharge lamp
Inventor: OYAMA MASAMITSU
IPC: H01J61/18
Filed: 1987-02-09
Abstract: PURPOSE:To enable much enlargement of output of luminous spectra in the wavelength range of 220 nm to 330 nm which is effective for hardening of a resist by making a specific pressure of xenon gas be sealed as buffer gas in a luminous tube which contains no mercury. CONSTITUTION:In a mercury vapor discharge lamp formed by making halogen, buffer gas, and at least one or more species of tin and bismuth as luminous substance be sealed in a luminous tube which contains no mercury, xenon gas of 5 Torr to 300 Torr are sealed as buffer gas. Because mercury is not used and at least one or more species of tin and bismuth, whose main bright line spectra exist in the range of 330 nm or less, are sealed in the lamp, ultraviolet rays in the effective wavelength range of 220 nm to 330 nm can be emitted effectively. Further, since xenon gas is used as sealed-in gas, the output in the effective wavelength range of 220 nm to 330 nm can be much enlarged compared with the case in which argon gas is sealed in the lamp.
