Title: Heating apparatus
Inventor: YAMAUCHI MASATO
IPC: F24C7/02
Filed: 1992-08-28
Abstract: PURPOSE:To prevent a glass part of an incandescent electric lamp from being destroyed owing to stress caused by a difference between the glass part and a socket part of the incandescent electric lamp in a heating apparatus even when the incandescent electric lamp for illumination of the inside of a heating camber is mounted on the upper surface of the heating chamber. CONSTITUTION:An incandescent electric lamp 1 is provided on the upper surface for illuminating the inside of a heating chamber 1. The incandescent electric lamp 1 comprises a glass part 1-a and a socket part 1-b, and is adapted to be mounted on a heat transfer plate 2 through a mounting plate 3 attached to the socket part 1-b. With the construction, after completion of the heating heat is transmitted from the heat transfer plate to the socket part 1-b and an abrupt temperature change of the socket part 1-b is prevented. Hereby, any stress caused by a difference between thermal expansion coefficients of the glass part 1-a and the socket part 1-b is moderated, and hence the glass part 1-b is prevented from being destroyed.

Title: Range finder
Inventor: OGAWA KENJI
IPC: G01C3/06
Filed: 1992-08-28
Abstract: PURPOSE:To make highly accurate measurement irrespective of shift of optical axis, contrast, or differential lightness possible, by calculating the distance upto an object to be measured based on relative positions of symmetrical right and left axes calculated on the basis of images imaged through a pair of image sensors. CONSTITUTION:Image sensors 3, 4 convert images of an object 5 to be measured, imaged through lenses 1, 2, into electric signals which are then subjected to A/D conversion 6, 7 and stored, as image data, in memories 8, 9. A microcomputer 10 accesses the memories 8, 9 to fetch image information and calculates distance upto the object 5. In other words, the computer 10 detects the positions X1, X2 of the symmetrical axes of the object 5 for left and right images imaged through the sensors 3, 4 and then calculates the difference (a) therebetween. The difference (a) corresponds to the parallax of the object 5 imaged through two lenses 1, 2 arranged on the left and right. This constitution allows calculation of distance R upto the object 5 based on the principle of triangulation.

Title: Color filter consisting of inorganic material and its production
Inventor: NAKAMURA RYUICHI
IPC: G02B5/20
Filed: 1994-09-26
Abstract: PURPOSE: To obtain an inorg. color filter in which a color layer is uniformly colored and high smoothness of the layer is maintained by using a material prepared by mixing an org. metal compd. and a transparent low melting point glass. CONSTITUTION: This color filter comprising an inorg. material is obtd. by depositing pixels produced by calcining a material of a mixture of an org. metal compd. and a transparent low melting point glass on a glass substrate. In the process of calcining, the org. compd. uniformly precipitates to cover the low melting point glass. The org. compd. thus precipitating is thermally decomposed into metal oxide, namely an inorg. pigment. By this method, the solid content as the material to form a filter which deposits on the glass substrate is only the low melting point glass powder. This means that it is unnecessary to consider the uniformity of dispersion of the pigment and the low melting glass powder during depositing on the glass substrate.  In the calcining process, the org. metal compd. is thermally decomposed to uniformly precipitate as an inorg. pigment having an extremely small particles size. Thereby, a color filter having color layers uniformly colored and high smoothness maintained is obtd.
