摘要:
A half toroidal CVT disk having an inner surface portion, an outer surface portion and a toroidal surface having a given machining allowance is centered with said inner surface portion worked prior to the heat treatment of said half toroidal CVT disk as the standard thereof, and then is chucked by a chuck mechanism. The toroidal surface of the chucked half toroidal CVT disk is ground by a grinding mechanism with the grinding wheel for grinding the half toroidal CVT disk in a state that one of said half toroidal CVT disk and said tool is inclined at a given angle with respect to the other.

A grinding apparatus for grinding a spline ball groove on a workpiece comprises a rod-shaped grindstone, having a distal end portion with a curved surface corresponding to the groove to be ground, and a spindle mechanism for rotating the grindstone. The spindle mechanism and the grindstone are supported by means of a supporter in a manner such that they are inclined at a given angle to an axis of the workpiece. A rotary dresser, which has a dress groove corresponding to the curved surface of the distal end portion of the grindstone, is disposed near the grinding apparatus. The grindstone can be reciprocated along the axis of the workpiece by a drive mechanism between the workpiece and the dresser without changing its angle of inclination.

A graft with a stent, includes: a stent composed of a resilient wire having a supporting frame comprising a wire having a zigzag shape forming top and bottom portions; and tubes being made of plain woven of polyester resin fibers and having a thickness of 20 &mgr;m to 100 &mgr;m. The tubes are disposed between inner surface and outer surface of the stent, and the inner tube surface and the outer tube surface are partially adhered to each other by a polyester resin. The graft is free from hindrance of blood from flowing by kink and/or arctation in a corner such as an arched portion, a curved portion, and meandering portion, is resistant to expansion and contraction and bending, and is fit to a shape of a blood vessel of a human body. The graft is usable for a total percutaneous intravascular surgery because it can be inserted into a sheath having a small diameter because of a thin artificial blood vessel, and is prone not to have leakage from a connection with a blood vessel. The stent does not directly contact an organism and is capable of being indwelt in an organism.

A surface preparation method and semiconductor device constituted so as to enable the prevention of carrier accumulation resulting from Si acting as a donor, without making the constitution of a semiconductor manufacturing apparatus complex. When forming an epitaxial layer either on the surface of a substrate, or on the surface of a base layer, Si or an Si compound that exists on the surface of a substrate, or on the surface of a base layer, is removed in accordance with a thermal cleaning process that uses an As hydride gas as the cleaning gas.

A intruder detecting apparatus for detecting a intruder invading an detection area defined in, for example, a window, entrance or apron region in front of one or more wall-mounted paintings includes a first sensor 2X having an detection area 7A defined in the front side of the objects 5 and 6 to be watched and the region upwardly of those objects 5 and 6 to be watched, and a second sensor 2Y having an detection area 7B defined in the front side of the objects 5 and 6 to be watched and the region downwardly of those objects 5 and 6 to be watched. A timer-equipped logic circuit 13 is provided in at least one of the first and second sensors 2X and 2Y. The other of the first and second sensors 2X and 2Y has an output path 17 provided therein for outputting a detection signal a from a detector 10 within such sensor to an external circuit. The timer-equipped logic circuit 13 generates an warning signal b when the timer-equipped logic circuit 13 receives the detection signal a from one of the sensors 2X and 2Y, which is provided with the timer-equipped logic circuit 13, and the detection signal a, outputted through the output path 17, within a predetermined time.
