摘要:
A photosensor system includes a photosensor array which is constituted by two-dimensionally arraying a plurality of photosensors and has a light-receiving surface, and a front light source which is arranged to face the light-receiving surface at an interval, and illuminates a rear surface of an object whose front surface is set on the light-receiving surface. An image reading assembly reads an object image by receiving light that is emitted by the front light source and passes through the object.

This invention reads image data of a subject by performing pre-reading operation while changing the image reading sensitivity at a plurality of stages immediately before the start of normal reading operation of a subject image, calculates the absolute difference value between adjacent pixels of lightness data of the read image data, and sets as an optimal reading sensitivity an image reading sensitivity having a maximum absolute difference value among calculated absolute difference values in a photosensor system having a photosensor array constituted by two-dimensionally arraying a plurality of photosensors, a driver circuit for supplying a drive signal to the photosensors, and a controller for controlling reading operation of a subject image and sensitivity setting. Even when ambient light changes or the characteristics of the photosensor change, an optimal image reading sensitivity can be set in accordance with the changes. Further, even when a position where the subject is placed in the detection area of the photosensor array offsets from a normal position in performing pre-reading operation, and the read image data contains a background pattern together with the subject image, a proper image reading sensitivity can be extracted and set without any influence of the background pattern. An image reading sensitivity setting method having high reliability can be provided.

摘要:
A vapor growth apparatus comprising a reaction chamber including a gas inlet, a diffuser section, the cross section of which gradually increases in a direction of the flow of gas supplied from the gas inlet, and a reaction chamber, which is coupled to the diffuser section and in which a substrate on which a thin film is to be formed is arranged, and a flow regulating member arranged, within the diffuser section, to make the flow speed of gas passing over the substrate uniform in a direction perpendicular to the direction of the flow of the gas. The flow speed of gas flowing over the substrate is made uniform in a direction perpendicualr to the direction of the flow of the gas, so that a thin film can be uniformly formed on the substrate in a direction perpendicular to the direction of the flow of the gas.

摘要:
Disclosed is a method for estimating, within a short time, the life of a cable insulating coating material containing an antioxidant in a suitable concentration based on the rate of decrease of the antioxidant and on the critical concentration of the antioxidant at which oxidative degradation rapidly proceeds. The method tests the coating material to examine its life, the coating material including a base polymer, and an antioxidant having a functional group suppressing an oxidative deteriorative reaction of the base polymer. The method includes performing a thermal degradation test on the coating material; determining the degradation levels and degradation rates of the coating material at two or more time points in the thermal degradation test, based on the ratio of the absorbance of the functional group of the antioxidant to the absorbance of the base polymer; and thereby evaluating the life of the coating material.
