Abstract: PURPOSE:To prevent a leakage current from flowing to a patient and a physician via a sheath connection section and a guide tube and avoid a danger such as burning and an electric shock by forming at least part of the sheath connection section connecting an operation section and a sheath or the guide tube with an electric insulating member. CONSTITUTION:A diseased portion is placed between a loop 28 and the front end of a sheath 2 while it is observed with an optical viewing tube 4. A high-frequency current is fed to the loop 28, and a pinched diseased section is burnt. When a liquid infiltrates into an electrode inserting hole 22 or a water droplet is formed between the electrode 5 and a guide tube 11, the liquid forms a conductive path and a current leakage occurs from an electrode receiver 21 to the guide tube 11 if the guide tube 11 is made of a conducting material such as a metal. However, the guide tube 11 is made of an electric insulating material, this current has no place to flow, as a result, no current leakage occurs. The current leakage through the electrode inserting hole 22 is prevented, and the burning and electric shock of a patient and a physician due to the current leakage can be prevented.

Filed: 1985-10-21
Abstract: PURPOSE:To prevent an ignition phenomenon at the time of marking to a combustible article, by controlling irradiation energy to an objective marking surface to a definite value or less. CONSTITUTION:Position orders of an x-direction order 11 and a theta-direction order 21 and the laser irradiation energy order 31 corresponding to each position are successively outputted from the order device of a control apparatus 8 and a reflective mirror is moved to the position corresponding to an order value to integrate the intensity of laser beam and, at the point of time when the quantity of energy at that position reached the order 31, laser beam is moved to the next position and the above mentioned procedure is repeated to control the irradiation quantity of laser beam at each position. For example, in the marking of an English character A, the acute angle (an a-range in a drawing) of the upper part of A is removed and the moving speed of laser beam 3 in the a-range is moved so as to be made faster than that at a straight line part to make the irradiation time of laser beam at each position of the character constant and the ignition of a wood box 9 is prevented. In the b-range and the c-range shown by the drawing, the overlapping of irradiation of laser beam 3 is avoided and the light emission of the wood box 9 is prevented.

Title: Luminaire
Inventor: MATSUSHITA NOBUO
IPC: G02B5/08
Filed: 1988-09-17
Abstract: PURPOSE:To make the spectral reflectance of a reflector on the bottom side thereof substantially identical with that near an irradiating opening end so as to reduce nonuniformity in color of reflecting light by forming an optical thin film on a reflecting surface of the reflector in such a manner as to become thicker gradually from the bottom toward the opening end. CONSTITUTION:An irradiating opening 13 is formed on one side of a revolution paraboloid reflector 11 provided with a light source 12 therein. An optical thin film 14 is formed on a reflecting surface inside the reflector 11 in such a manner as to become thicker gradually from the bottom of the reflector 11 toward the opening 13. Light radiated from the light source 12 has a tendency that the reflection zone of the reflected light is shifted in a short wavelength by the thin film 14 in such a manner that an incident angle alpha at a point (a) on the bottom side of the reflector 11 is small while the angle alpha at a point (b) near the opening 13 is large. Accordingly, a reflected wavelength zone is shifted in a long wavelength because the thin film 14 is thicker toward the opening 13. Therefore, in the reflector 11, a spectral reflectance on the bottom side is substantially identical with that near the opening 13, and as a result, nonuniformity in color can be prevented.
