Title: Method for detecting crystal defect by use of confocal optical system
Inventor: OGAWA TOMOYA
IPC: G01N21/956
Filed: 1993-10-29
Abstract: PURPOSE:To provide a method for detecting a crystal defect by use of a confocal optical system in which the crystal defect can be easily detected for the whole surface of a crystal only by performing unidimensional scanning, and the noise light can be reduced to enhance resolution. CONSTITUTION:An infrared laser beam B is horizontally incident from the side surface of a crystal, the scattered lights from crystal defects d1-d3 present along the passing route of the laser beam are converged by an objective lens 4 arranged above the crystal, and transmitted to an imaging lens 7, and a detecting aperture 5 having a slit 6 consisting of a groove width W of the same degree as the wavelength of the infrared ray is situated in the focus position of the objective lens between the objective lens and the imaging lens, and arranged so that the longitudinal direction of the slit is parallel to the laser beam. For each diffraction figure of each crystal defect imaged on a sensor through the slit, the light intensity is integrated to the diffracted light of a prescribed degree, and each crystal defect is detected from the resulting light intensity.

Abstract: PURPOSE:To prevent burning by mounting an insulating transformer on the side of an AC output from a DC-AC converter converting a DC out put into the AC output. CONSTITUTION:An inverter device 2 also functioning as the prevention of burning is connected to a commercial AC system 1 through a pole transformer 3. The inverter device 2 has a DC AC converter 4 and a base drive circuit 5 controlling the converter 4, and a solar cell 8 as a DC power supply is connected on the DC input side 4b of the DC-AC converter 4. In this case, the primary winding side 7a of an insulating transformer 7 is connected to the AC output side 4a of said converter 4 through a breaker 6, and a secondary winding 7b for the insulating transformer 7 is connected to a distribution line 3b. The number of turns of the insulating transformer 7 is brought to 1:1. Consequently, even when a ground fault is generated on the series circuit 9 side, the inverter device 2 is separated from the ground system of the AC system 1 because the AC system 1 is connected through the insulating transformer 7. Accordingly, flow through the series circuit 9 side through the converter 4 of overcurrents from the AC system 1 is prevented.
