Abstract: PROBLEM TO BE SOLVED: To provide a resin degree-of-curing measuring apparatus for accurately measuring the degree of curing in resin. SOLUTION: When reflection light is divided into two and a wavelength constituent where the change in intensity is smaller to the degree of curing in resin is used as a reference, an external factor simultaneously affects the intensity of both wavelength constituents even if the intensity of a larger wavelength constituent is changed by the external factor such as the temperature change in a target or the like, thus preventing the correlation values from being affected by the external factor other than the degree of curing in resin. An arithmetic unit 10r obtains an output signal according to the intensity of the wavelength constituents after resin coating and before the drive period of a curing-accelerating means, and after resin coating and during a drive period in the curing-accelerating means. Although the correlation values are greatly affected by the degree of curing in resin, it is not affected by other factors easily. As a result, the correlation values accurately change before resin curing and after curing, thus accurately detecting the degree of resin curing.

Abstract: PROBLEM TO BE SOLVED: To provide a spot light source device equipped with a structure in which leakage light in the device is shielded, and elevation of inside temperature can be suppressed effectively. SOLUTION: Between an intake port (54) and a variable aperture (112), a control plate (55) is installed. This control plate (55) functions as a shield member for preventing that illumination light (L) is directly irradiated to parts , and on the other hand, it functions as an exhaust device since it is arranged on a circulation path of the outside air which has been taken in from a fan (15) and which has proceeded to a space between a shield plate (50) and a control device (100) via the intake port (54) after having detoured the light source (2). As for the outside air taken in by a fan (15), temperature elevation of the device inside is effectively suppressed since it is positively exhausted by existence of the control plate (55).

Abstract: PURPOSE: To improve the stability of the operation of a gas discharge tube and prolong its life by bringing spacers into contact with the back face of a focusing electrode support member and the front face of an anode section, pressing the anode section to the front face of an anode support member, and keeping the interval between a focusing electrode section and the anode section. CONSTITUTION: Spacers 50 are arranged between the back face 21b of a focusing electrode support member 21 and an anode fixing plate 24b on both sides in an anode storage recess 25. The back face 24aA of an anode fixing plate 24a is pressed and fixed to the surface 25a of the anode storage recess 25 by the pressing force of the spacers 50. The interval between a focusing electrode section 29 and an anode section 24 can be invariably kept constant by the spacers 50. The trigger voltage of 350-500V, for example, is applied between a hot cathode 31 and the anode section 24. The thermoelectrons emitted from the hot cathode 31 discharge ultraviolet rays from an opening window 30 via an arc discharge. Since the anode section 24 is firmly held by an anode support member 22 and a focusing electrode section 29 is held by the focusing electrode support member 21, they are not deformed at the high temperature caused by continuous luminescence over a long period.

Abstract: PURPOSE: To make deformation hardly cause even under high temperature due to the long-hour continuous emission by sandwiching a positive electrode part by spacers, and holding the positive electrode part between a back face of a convergent electrode support member and a front face of a positive electrode support member. CONSTITUTION: Trigger voltage is impressed between a hot cathode 31 and a positive electrode 24b. A thermoelectron emitted from the hot cathode 31 then passes through a slit 32a of a discharge rectifying plate 32, and reaches the positive electrode 24b while converging by a convergent opening 29a of a convergent electrode part 29. Arc discharge is generated in front of the convergent opening 29a, and an ultraviolet ray taken out of an arc ball by this arc discharge is emitted outside by passing through a peripheral surface of a vessel after passing through an opening window 30. Since a positive electrode part 24 and the convergent electrode part 29 become high temperature, this heat is radiated outside at proper time. Since the positive electrode part 24 is held in a positive electrode support member 22 by spacers 50, deformation is hardly caused even under high temperature due to the long-hour continuous emission, and positional accuracy between the positive electrode part 24 and the convergent electrode part 29 is excellently kept.
