Abstract: An image reading system constructed as in the following in order to shorten a time from a turn-on of an original illuminating lamp to a substantial image reading operation and perform a high speed scanning. A position and size of an original which do not require a stable light amount of the original illumination lamp are read during a forwards pre-scanning operation period (tps) during which the light amount is unstable after the start of the pre-scanning. During the period (tacs1) after a timing (t1) when the light amount becomes stable during the forwards pre-scanning operation, an original color information is read from an area of the original from which the color information cannot be read during the backwards pre-scanning operation. Accordingly, the total time required for the pre-scanning operation can be made shorter than that required by a conventional pre-scanning operation which reads the original information and color information only during the forwards pre-scanning operation.

Abstract: There is disclosed an electrostatic holding apparatus in which a voltage is applied to an conductive electrode covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The main component of the insulating dielectric layer is ceramic containing 0.1-30 wt. % of an atomic metal, and the volume resistivity of the metal-containing ceramic at 20° C. is 108-1013 &OHgr;·cm. The metallic element is Mo or W. In the electrostatic holding apparatus, since the volume resistivity of an insulating dielectric layer of an electrostatic attraction portion is decreased, a strong electrostatic force can be generated. Also, there can be maintained the capability of allowing removal of an object at the time of stopping application of voltage. Further, since neither fine cracks nor pores remain in the insulating dielectric layer after sintering, the withstand voltage is high.

Abstract: There is disclosed an electrostatic holding apparatus in which a voltage is applied to an electrode formed of a conductive layer disposed on an insulator layer and covered with an insulating dielectric layer in order to cause the insulating dielectric layer to electrostatically attract an object. The electrostatic holding apparatus is formed of a sintered body in which a thermal expansion mitigating layer is disposed between the insulating dielectric layer and the conductive layer and/or between the conductive layer and the insulator layer. The insulating dielectric layer, the conductive layer, the insulator layer, and the thermal expansion mitigating layer are superposed and press-formed in an unfired state to obtain a green body, which is then sintered to obtain the sintered body.

Abstract: A heating device is formed by a heating plate formed of silica and having a heating surface for heating an object to be heated, a heating element having a predetermined pattern and fixed to a surface opposing the heating surface of the heating plate, and a reflecting plate formed of silica and brought into tight contact with the surface of the heating plate on which the heating element is formed. This heating device is arranged in a processing vessel in a CVD apparatus, and a semiconductor wafer is placed on the heating device. A process gas is supplied into the processing vessel while the semiconductor wafer is heated, thereby forming a predetermined film on the semiconductor wafer.

Abstract: An improvement is proposed in a ceramic heater which is an integral body comprising a flat substrate plate made from an electrically insulating ceramic material, e.g., fused silica glass, and a layer of an electroconductive material formed on one surface of the substrate plate in a pattern of an electric heater element. One of the surfaces of the insulating substrate plate, on which the heater layer is formed, is subjected to a surface roughening treatment, e.g., by sand blasting, prior to the formation of the heater layer so as to be imparted with a specified surface roughness so that the heat generated in the heater layer and transmitted to the other surface as infrared rays is irregularly scattered .
