    摘要: Provided is an optical characteristic measuring probe which can detect the position and the direction of the leading end of the probe without affecting a monitoring image. The bendable optical characteristic measuring probe is provided with a light guide body (71), which transmits light emitted from a light source and irradiates a subject to be measured with light, and a guide tube (70), which holds the light guide body (71) such that the light guide body freely rotates about the axis and is freely displaced in the axis direction. The light guide body (71) guides at least two types of light, i.e., measuring light for measuring the optical characteristics of the subject to be measured, and position determining light for measuring the position of the light guide body. On the side surface of the guide tube (70), a mark (M) having the characteristics of transmitting the measuring light and returning only the position determining light to the light guide body is provided.

    摘要: A manufacturing apparatus of the present invention has a pair of dies that form each cylindrical surface, and a plane member that forms side surfaces of an element. The upper die and the lower die has a cylindrical surface which is worked so as to have generatrix which connects intersection points between a non-arc axis and a cylindrical section and between an arc center axis and the cylindrical section. The plane member is pressed against reference surfaces of the upper die and the lower die. In this state, a glass material is put between the upper die and the lower die, and a distance between the upper die and the lower die is decreased. As a result, the cylindrical surfaces of the upper die and the lower die and the plane of the plane member are transferred onto the glass material.

    摘要: To convert a pixel value obtained from a non-reference photoelectric conversion characteristic into a pixel value obtained from a reference photoelectric conversion characteristic without variation, and to prevent generation of fixed pattern noise in an image. An image sensor 3 is constituted of pixels having photoelectric conversion characteristics, in which a linear characteristic is on the low luminance side with respect to an inflection point, and a logarithmic characteristic is on the high luminance side with respect to the inflection point. A conversion information storage 68 stores, as conversion information, coefficients “c”, “d”, “e”, and “f” of two kinds of linear functions (y=c·log(x)+d, and y=e·log(x)+f), which are approximation equations expressing the logarithmic characteristic of each of the pixels, where y designates a pixel value, and x designates a luminance value of incident light. A linear converter 64 converts a pixel value obtained from the logarithmic characteristic into a pixel value obtained from the linear characteristic by using the approximation equations specified by the coefficients.

    摘要: An injection mold composed of a movable mold and a fixed mold. The movable mold has bases, a heat insulating layer and a surface processed layer, and the fixed mold has a base. A heat insulator is provided on the inner circumferential surface of the base of the movable mold at a part forming a wall of a cavity. The heat insulating layer is in the rear of the surface processed layer, and therefore, the transfer accuracy of a fine configuration of the surface processed layer is improved. Additionally, since the heat insulator is provided adjacent to the fine configuration, heat radiation from resin is inhibited, and the transfer accuracy of the fine configuration is further improved.
