Title: Visual field direction converting optical system for endoscope
Inventor: KANAMORI IWAO
IPC: A61B1/00
Filed: 1988-10-18
Abstract: PURPOSE:To prevent the generation of a shift and an astigmatism in the visual direction by providing a stabilizing optical element in which a shape and a size of the outside diameter are equal to those of a visual direction converting prism. CONSTITUTION:The title optical system consists of a visual direction converting prism 4 which is constituted so that light beams reflected by the reflecting surface 4b are reflected by the refracting surface 4a, and a stabilizing lens 8 which is a circular lens whose outside diameter is the same size as that of the visual field direction converting prism 4, and gives a refracting action to reflected lights from the refracting surface 4a and emits it to an objective lens. Also, the surface 4b of the visual field direction converting prism 4 and the surface 8a of the stabilizing leans 8 are joined by making an acute angle with the longitudinal axis directions L, L' of an endoscope. Accordingly, since both the visual field direction converting prism 4 and the stabilizing lens 8 are formed by splitting them sectionally, positioning at the time of joining both of them can be executed exactly by only dropping down in order into a slender cylinder. In such a way, the generation of a shift and an astigmatism in the visual field direction is decreased.

Title: Refrigerator
Inventor: NISHIMURA KOICHI
IPC: F25D11/00
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To remove dust and oil component adsorbing the dust while decomposing by providing a condenser having surface coated with an optical catalyst, and a light for irradiating the condenser with light. SOLUTION: A semiconductor other than titanium oxide may be employed as an optical catalyst but titanium oxide is most preferable in view point of non-water solubility, stability, or the like. When cooling air passes through a condenser 9, dust and oil component adsorbing the dust contained in the air adhere to the cooling air suction side of the condenser 9. The optical catalyst reacts on the light emitted from a light 10 to decompose dust adhering to the condenser 9 thus removing dust from the condenser 9. Since the oil component adsorbing the dust is decomposed, dust does not adhere easily to the condenser 9 and the dust which can not be decomposed through catalytic action can be removed easily, if any.

IPC: H04N1/40
Filed: 1992-09-04
Abstract: PURPOSE:To set the optimum binarized threshold value in a hardware structure of a small scale and in a short processing time. CONSTITUTION:A primary change point number histogram is produced by a primary change point number histogram production part 31, and a secondary change point number histogram is produced by a secondary change point number production part 32 based on the primary change point number histogram. Then a primary change point number lower limit value detecting part 33 detects the lower limit value of the reference primary change point number in a section where the longest secondary change point number of 4 exists in the secondary change point number histogram. A logical optimum value searching range detecting part 34 decides a searching range held between the center two values out of four threshold values corresponding to the lower limit value in the primary change point number histogram. Then a logical optimum value searching part 35 searches the threshold value that minimizes the primary change point number in the searching range and outputs the threshold value as the binarized threshold value TH. As a result, the binarized threshold value is set at a high speed and in a hardware constitution of a small scale.
