A device for measuring tooth surface deviation includes a contact detector that measures the deviation at the tooth surface of a dresser with respect to a grinding tooth surface formed on a helical grinding tooth of a grinding tool when the grinding tool and a dresser toothed wheel are rotated synchronously in a state in which the grinding tooth surface and the dresser tooth surface of the dresser toothed wheel can be brought into contact, and detects contact between the grinding tooth surface and the dresser tooth surface; and a controller that changes the speed of rotation of the dresser toothed wheel in such a way that the detection result of the contact detector comes within the range of contact determination data, and also measures the amount by which the grinding tool and the dresser toothed wheel have been changed in one revolution of the dresser toothed wheel.

摘要:
Provided are a rotating electrical machine and a method for manufacturing the rotating electrical machine, wherein the tapered surface of a plate-side tapered section and the tapered surface of a shaft-side tapered section are bonded with pressure by having forces operate between a plurality of plate-side protruding sections and a plurality of shaft-side protruding sections n the directions wherein the plate-side protruding sections and the shaft-side protruding sections are separated from each other. Thus, a ring core is fixed to a shaft.

A process for producing a carbon structural body is provided, with which a carbon structural body having any of various nanostructures can be produced inexpensively and efficiently. The method includes forming a carbon-containing material into a pattern, coating the obtained pattern with a proto-shaped mold, and calcining and carbonizing the coated pattern.
摘要:
A device containing a far infrared radiation-emitting material over which fuel or other fluids such coolant fluid can flow such that far infrared radiation is emitted into the liquid fuel or coolant resulting in the reduction of toxic exhaust gas and the improvement of the combustion efficiency. The compositions includes a material that can emit far infrared radiation, such as magnetite or quartz-feldspar porphyry. Generally, the far infrared radiation emitting material is contained in a matrix that radiation being emitted to disperse out of the matrix and into the surrounding environment. The preferred matrix is a glass composition even though other materials such as plastics may be used. Preferably the glass composition is in the form of glass beads, which can be any shape but preferably pellets or balls. Also the far infrared radiation-emitting material can be embedded in other materials such as clear plastic, clear silicone or clear fiberglass beads.
