Title: Resistive terminator
Inventor: KONISHI TOSHIKATSU
IPC: H01P1/26
Filed: 1984-11-05
Abstract: PURPOSE:To use the titled terminator for a large power and also to improve heat dissipation effect by providing a metallic body processed in taper in the inside of a waveguide for terminator and adhering closely a plate shape radio wave absorbing body on a slope of the metallic body. CONSTITUTION:A tapered metallic body (metallic body having triangle cross section) 4 is provided on the plane E of a waveguide 1 and a thin radio wave absorbing body 5 is fitted along the slope. Since even the thin radio wave absorbing body 5 attenuates sufficiently a microwave, the same effect as the case that a tapered radio wave absorbing body is fitted to the plane E of the waveguide is obtained equivalently thereby improving the heat dissipation effect without giving effect on the reflecting characteristic. Thus, thermal deformation exerted to the radio wave absorbing body 5 is reduced and the body is used with much power. Further, it is not required to shape the radio absorbing body to a taper form and a thin plate is used, then the production cost of the radio wave absorbing body is less.

Title: Housing for extra-high voltage mercury lamp
Inventor: IGARASHI TADANAO
IPC: F21V29/00
Filed: 1986-09-30
Abstract: PURPOSE:To enable stable exposure by removing the destruction of a lamp due to the accumulation of heat or unstable intensity of illumination due to supercooling by adjusting the ventilation in a housing according to the detected voltage or the detected current of the lamp. CONSTITUTION:When high-frequency high voltage is applied to the extra-high voltage mercury lamp 2 in a housing 1 from a power source 7, a discharge is generated in the lamp 2, the vapor pressure of mercury is gradually made higher and the lamp is lit. The ultraviolet light generated from the lamp 2 is converged on a cold mirror 5 by a reflector 3 and is guided to an exposed object. The voltage of the lamp is gradually raised and the current of the lamp is gradually reduced. The voltage of the lamp cannot be raised sufficiently under a supercooling condition and the current of the lamp is not reduced sufficiently so the lamp is not supplied with rated power and the intensity of illumination is not increased. For this reason, the voltage of the lamp under the rated voltage is detected by a detector 11, e.g., the voltage of a fan 4 which ventilates the housing 1 is reduced by a fan controller 6 and if the number of revolution is reduced, the ventilation in the housing 1 is made weaker, the temperature of the lamp 2 is raised and the vapor pressure of the mercury is increased, the voltage of the lamp is increased and the intensity of illumination is maintained appropriately under the rated power.
