Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a uniform heater of which observation at site can be made with an X-ray beam. SOLUTION: A specimen sample 1 is supported by a thermal insulating material 4. A ceramic heater 2 for use in heating operation is arranged outside the specimen 1, a reflector 3 for use in reducing thermal leakage caused by radiation is arranged so as to constitute a heating furnace. An X-ray generating device 5 and an X-ray detector 6 for performing an observation when the specimen sample is melted are arranged at a right side and a left side of the heating furnace. The ceramic heater 2 is constituted by two kinds of ceramics formed by a chemical vapor phase deposition method (CVD), one being an electrical conductive PG and the other being formed by PBN or the like.

Title: Mold for molding resin
Inventor: TAJIMA HIDEKI
IPC: B29C45/26
Filed: 1989-11-20
Abstract: PURPOSE:To regulate thermal conductivity automatically by constructing the connection between the part to be heated and the part to be cooled into a specified structure in the mold of a hot runner type. CONSTITUTION:A hot chip 1 has the resin-flowing path 5 in which resin is kept in molten state, and the sprue bush 2 has the resin-flowing path 6 solidifying also the resin therein, when the resin in a molded object is cooled and solidified. The tip of the hot chip 1 is formed into a protrusion with the member 11 having the relatively small coefficient of linear thermal expansion. On one hand, the sprue bush 2 has the substantially large coefficient of linear thermal expansion relatively to the material of the hot chip, and the tip of the sprue bush is formed into a depression. These both members are fitted to each other, and the seal for resin is formed. When the temperature of the sprue is raised due to the thermal conductivity from the hot chip, the sprue is expanded larger, whereby a gap 8 is generated on the periphery of their fitted part and the thermal conductivity is reduced. Reversely, when the sprue is too cooled due to the effect of the low temperature of a molded body, the sprue is shrunk and the gap becomes small, thereby increasing the thermal conductivity from the hot chip. Thus, the temperature of the sprue is automatically regulated.

Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To correct red-eye by varying a data correction amount with respect to original image data in a red-eye area depending on a place in the red-eye area (e.g. middle or surrounding of the red-eye area) so as to generate a more natural face image. SOLUTION: In a distribution state of a saturation (a) and a lightness (b) of an original image along a line of a red-eye area, the red-eye is corrected by reducing the saturation and the lightness of the original image. A degree of this reduction changes depending on a place in the red-eye area. The reduction rate of saturation (e) and lightness (d) with respect to the original image is expressed in percentage. Then the reduction rate is changed larger toward the center of the red area to obtain a distribution of the saturation (c) and lightness (d) after the correction. Then an arithmetic operation of restoring the color space expressed by the hue of the original image and the saturation and the lightness after the correction to a color space of the original image data is conducted and generation of an image whose red-eye is corrected is made complete.  Or stepwise reduction in the saturation (g) and lightness (h) is effective.
