A stock device 11 for storing cutter blades 21 for a cutting device 10, which includes a case body 40 provided with a receiving section 41 for the cutter blades 21. Within the case body 40, engagement surfaces 43A are provided so as, when the cutter blades 21 are stored in the receiving section 41, to ensure the orientation of the cutter blades 21 to a constant direction when a cutter blade 21 is mounted onto the cutting device 10. Also, the case body 40 stores organic solvent L therein for washing the cutter blades 21, and is arranged so as to be able to dissolve and remove adhesive and the like adhered to a blade 21B with the organic solvent L.

The present invention is a static pressure pad for supporting both sides of a raw wafer without contact by a static pressure of a fluid supplied to the both sides of the raw wafer in a double-disc grinding machine for a semiconductor wafer, wherein in patterns of lands to be banks of surrounding pockets formed on a surface side of supporting the raw wafer of the static pressure pad, an outer circumferential land pattern required to support the raw wafer is a concentric circle with respect to a rotation center of the raw wafer, and a land pattern inside the outer circumferential land pattern is a non-concentric circle with respect to the rotation center of the raw wafer and asymmetrical with respect to all the straight lines which bisect the static pressure pad. With this static pressure pad, there is provided the double-disc grinding machine and a double-disc grinding method for the semiconductor wafer, which can minimize a “middle ring” of average components obtained by averaging a nanotopography of the wafers after the double-disc grinding.

An optical receptacle according to the invention includes a columnar stub ferrule having an optical fiber inserted into a center line connecting both opposite end faces; a cylindrical sleeve into which a part of the stub ferrule is inserted; and a housing in which a through hole is formed, which houses the stub ferrule and the sleeve in the through hole, which holds a part on a side on which the stub ferrule is not inserted into the sleeve, with a projecting portion formed in the through hole, and which surrounds a side surface of the stub ferrule on the side on which the stub ferrule is not inserted into the sleeve. The optical receptacle has a space between the side surface of the stub ferrule on the side on which the stub ferrule is not inserted into the sleeve and an inner peripheral surface of the housing opposing the side surface.

A motorcycle includes a guard frame provided near an upper portion of a vehicle body of the motorcycle that is arranged to reduce or prevent damage to the components of the motorcycle in the event of an overturn of the motorcycle. The guard frame includes a pair of guard frame rails, each rail extending in a longitudinal direction of the vehicle body. A connecting portion connects the rear end portions of the rails. The front end portion of each rail is fixed to a body frame of the motorcycle. The connecting portion is supported by the body frame for pivotal movement about a pivot axis. The rails have a normal bow shape that projects outwardly. In some arrangements, an intermediate portion of each rail is formed of a material having lower rigidity than a material of the front and rear end portions of the rail.
