IPC: B24D3/00
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a cup-shaped grinding tool capable of improving the service life of the tool in achieving the groove machining or dressing using a tip face. SOLUTION: In the cup-shaped grinding tool 10, a cylindrical grinding part 14 is excellent in cutting quality since a grinding structure in which super-fine abrasive grains 26 are bonded by a metal bonding agent 28 is lined by a thin metal lining layer 40 and formed thin, and the relatively sufficient rigidity necessary for the grinding machining of a groove bottom or the dressing machining can be obtained by its cylindrical shape. In addition, even when the super- fine abrasive grains 26 on a forward end face 16 of the cylindrical grinding part 14 are consumed or fallen out, the super-fine abrasive grains 26 therebelow appear on the tip face 16 to contribute to the grinding action, and thus, the service life of the tool is more excellent than that of a conventional tool.

Filed: 1995-06-15
Abstract: PURPOSE: To provide a disconnector for an electric vehicle which can simultaneously or separately open and close plural disconnectors by forming step differences in an operating member, and boring mutually opposing communicating holes on respective surfaces. CONSTITUTION: When a hooking bar 21 of a disconnecting bar 20 is inserted into a hooking hole 42a arranged on an operating surface 42 of an edge tip installing tool 40, since an under head dimension L of the hooking bar 21 and a thickness L of the operating surface 42 are the same with each other, it does not reach the hooking hole 42a of another knife switch-shaped disconnector arranged in the symmetry in parallel to each other, and only one disconnector can perform opening-closing operation. On the other hand, when the hooking bar 21 is inserted into a hooking hole 41a arranged on a stepped operating surface 41, since a dimension between stepped operating surfaces 41 of the two disconnectors is not more than the under head dimension L of the hooking bar 21, opening-closing operations of both disconnectors are simultaneously performed.  Therefore, the prevention of an electric shock and an increase in the working efficiency can be attained.

Title: Method and apparatus for producing glass granular material
Inventor: TAKAHASHI TAKAHIRO
IPC: C03C12/00
Filed: 1985-08-07
Abstract: PURPOSE:To efficiently produce the titled granular material having even size even from devitrifiable glass by cutting plural grooves in one direction on the glass and cutting plural second grooves crossing the first grooves and cutting the glass along the grooves. CONSTITUTION:The molten glass 12 in a melter 10 is discharged from the melter 10 at a temp. higher than the devitrification temp. of the glass and bitten by the first couple of rolls 14. The glass is rolled in the form of a sheet and simultaneously the first grooves 28 extending in the traveling direction of the sheet are formed. The sheet material 22 is bitten by the second couple of rolls 16 while being cooled by a cooling plate 26 and the second grooves 30 are cut in the direction orthogonal to the first groove 28 at specified intervals. The sheet material 22 cut with the grooves 28 and 30 is sent to a cutter and cut along the grooves 28 and 30 to form a granular material. Since the glass is cut in two steps, the effect of the deformation of glass is reduced. Since the viscosity of the glass is increased by cooling when the glass is bitten by the second couple of rolls 16, the cut grooves are hardly deformed and the glass granular material having even size can be obtained even from low-viscosity glass.
