Filed: 1979-10-31
Abstract: An endoscope comprises an internal space (17,18) extending through the substantially whole length of the endoscope, at least one cylindrical end portion (2,10) which is connected to the endoscope and provided with an air port (16, 50, 51) open to the outside of the endoscope, only through which the internal space (17,18) communicates with the open air, and a fluid-proof cap (19) one end (19a) of which is open for insertion of the cylindrical end portion (2,10)and the other end (19b) of which is closed, whose inner peripheral wall (20) is shaped complementary to the outer peripheral wall of the cylindrical end portion (2, 10), and which is provided with an 0-ring (22) disposed in the inner peripheral wall (20) to seal in a fluid-tight state between the outer peripheral wall of the cylindrical end portion (2, 10) and the inner peripheral wall (20) of the cap (19), and also provided with a fitting mechanism (23, 24; 29, 30, 32, 33; 101;102;55, 59) for detachably connecting the cap (19) to the cylindrical end portion (2, 10). Where the cylindrical end portion (2, 10) of the endoscope is pushed into the cap (19), the cylindrical end portion (2, 10) is sealed in a fluid-tight state. At this time, air held in the internal space (17, 18) of the endoscope is more compressed. When, therefore, fine holes or cracks are produced in the endoscope, the compressed air prevents a washing or disinfecting liquid from being carried into the internal space (17, 18) of the endoscope. Further where the endoscope is dipped in the water, generation of air bubbles in the water informs the operator of the presence of such defective parts as well as the locations thereof.

IPC: H01J65/04
Filed: 1993-06-14
Abstract: PURPOSE:To light many discharge lamps by means of a small number of high frequency generating device by transmitting high frequency electromagnetic wave from a high frequency generating means to a discharge lamp provided with an antenna by means of a waveguide so as to generate surface wave discharge. CONSTITUTION:When a high frequency electromagnetic wave of 600MHz is oscillated from a high frequency oscillator 3, it is transmitted inside a waveguide 2 and transmitted to each antenna 15 of each discharge lamp 1. The antenna 15 supplies the transmitted high frequency to the inner space of a discharge container 10 so as to generate surface wave discharge on the inner surface of the container. That is, as the frequency of the electromagnetic wave supplied to the lamp 1 is very high, surface wave discharge is generated along the tube wall of the container 10. This glow discharge is spread throughout the inner wall surface of the container 10 so as to generate light emission from the whole surface. simultaneous lighting becomes possible by attaching a plurality of lamps 1 to the waveguide 2 for transmitting high frequency and number of the oscillators in use can be saved.
