Title: Laser guiding device
Inventor: MASUBUCHI RYOJI
IPC: A61B18/20
Filed: 1988-10-03
Abstract: PURPOSE:To facilitate the positioning of guide light to processing laser light by attaching the outlet side of a fiber to an attaching part for attaching the fiber in alignment with the axis of the emitting light, and by providing a light axis adjusting mechanism for adjusting the axial of the emitting light. CONSTITUTION:The emitting end 30 of a fiber 26 for guide light is located in the rear of a half-mirror 24, being opposed thereto, laser light emitting from the emitting end 30 emits in alignment with a laser guide 14 in a hand piece 16. Further, the light axis adjustment is made in such a way that the front end part of the guide light fiber 26 is slid back and forth, relative to an insertion hole 28 in a support frame 25 so as to select the position of the emitting end 30 after loosensing a fastening nut 29, and accordingly, the focusing position of the guide light varies so as to adjust it to the focussing point (f) of processing laser. With this arrangement, the common part between the processing laser guide 14 and the guide light optical path is very short within the hand piece 16, thereby affection upon shift of the focusing point is extremely small.

Title: Carbon-containing refractory composition compounded with xylene-modified phenolic resin binder
Inventor: IDE ISAMU
IPC: B22D11/10
Filed: 1992-09-18
Abstract: PURPOSE:To provide carbon-containing refractory composition excellent in strength and spalling resistance. CONSTITUTION:The carbon-containing refractory composition comprising carbon powder, one or more kinds of metals selected from Al, Mg, Ca, and Si or their alloy, and a refractory aggregate. The composition is compounded with a xylene-modified phenolic resin as a binder. The polycondensation reactions of hydroxyl groups and methylol groups existing in the phenolic resin enhance the three-dimensional crosslinking density of the refractory composition, and the formation of the carbon-bonded product having the high three-dimensional density in the structure of the carbon-containing refractory provides a high strength for the refractory. Since the methyl groups contained in the xylene hardly contribute to the polycondensation reaction caused by the receiving of heat, the irregular crosslinking densities are generated in the three- dimensional carbon-bonded product, thereby permitting to soften the structure of the refractory.
