Abstract: PURPOSE:To contrive the stabilization of the quality of the film formed on a wafer by gas-phase growth by arranging a non-oxidizing gas blower for blowing a non-oxidizing gas downward into the second duct surrounding at a distance to form a non-oxidizing atmosphere region. CONSTITUTION:The first duct 1 and the second duct 2 which surrounds at a distance are provided and a non-oxidizing gas blower 3 is arranged in the periphery of the first duct 1. That blower blows a non-oxidizing gas such as nitrogen gas downward to form a non-oxidizing atmosphere region 3a in the part of a wafer 100. The non-oxidizing gas which was blown is partly adsorbed by the inside first duct 1 and the rest of it is adsorbed by the outside second duct 2 which adsorbs the external atmosphere in addition to the non-oxidizing gas. Accordingly, the insulating film can be formed with the stable film quality and the leakage to the outside can be prevented perfectly, thereby reducing the risk remarkably.

A font determining means 3 counts the number of unreadable characters at every page of an input document with respect to each font of dictionaries 11, 12... and determines the font, where the number of unreadable characters is minimum, as the font of this page. A font selecting means 4 selects respective fonts at every page of the input document in the first stage and selects the font, which is determined by the font determining means 3, in the second stage. A threshold selecting means 5 selects a decision threshold level different between the first stage and the second stage. Thus, characters are efficiently read with high precision.

Abstract: PURPOSE:To permit a work to be worked into the state having no dimension error at room-temperature by controlling the temperature of lubricating-oil so that the temperature difference between the temperature of the lubricating-oil and that of grinding liquid is not varied, independently from the temperature variation. CONSTITUTION:Into an arithmetic circuit 40, each value of the temperature tc of grinding-liquid, temperature th of lubricating-oil, and the room temperature tr are inputted from temperature detectors 30, 38, and 44. When the room temperature tr rises, said arithmetic circuit 40 operates a cooler 36 so that the temperature difference between the temperature tc of grinding liquid and the temperature th of lubricating-oil decreases, and then the temperature th of lubricating-oil lowers. While, if the room-temperature tr lowers, the temperature th of lubricating-oil is increased by the operation of a heater 35. Thus, a work can be worked into the state having not dimension error at room-temperature tr.
