Abstract: Disclosed are a silicon carbide sintered body and a sliding component using the same, and a protective body which, even when fine cracks are generated due to thermal shock or mechanical impact over prolonged use, are capable of inhibiting development of the cracks. The silicon carbide sintered body contains silicon carbide grains as a major component and has a relative density of 95% or more. On an observation surface of the silicon carbide sintered body, coarse silicon carbide grains 1b having a surface area of 170 ?m2 or more occupy 6 area % or more and 15 area % or less. The silicon carbide sintered body has excellent mechanical properties such as strength and rigidity. Even when fine cracks are generated due to thermal shock or mechanical impact, coarse silicon carbide grains 1b are capable of inhibiting development of the cracks.

Abstract: In a data processing apparatus, data stored in a storage section are retrieved according to a desired retrieval condition so as to be displayed on a display section. When the retrieved data are displayed on the display section, not only the retrieved data but also the retrieval condition are displayed. As a result, both the retrieved results and the retrieval condition can be exactly recognized on the display screen at a glance.

Abstract: An object of the invention is to easily and firmly read an image and to reduce power consumption. An image reading and displaying apparatus comprises a scanner for reading an image of a document arranged on the side of a read face where photocells are arranged in a matrix form, to output image information, a RAM for storing the image information from the scanner and a display device of a light transmitting type such including a display face for displaying the image information stored in RAM, the display device being such arranged that a back face of the display face contacts with a back face of the read face. Since the back face of the display face is arranged so as to contact the back face of the read face, an operator can confirm the image to be read, whereby the image can be read with certainty.
