A groove is formed on one end face side of a cage including a plurality of pockets for holding individually rolling elements which extends circumferentially along a full circumference of the cage about a rotational center thereof and has a bottom portion which communicates individually with the plurality of pockets, and a distal end portion of a nozzle of an oil supply unit is inserted into the groove, whereby the generation of disturbance to airflow and negative pressure in the vicinity of an opening of the nozzle is suppressed when a rolling bearing rotates, so that lubricating oil supplied from the nozzle is allowed to reach the rolling elements in an ensured fashion.

There is provided a composite memory device including a recording medium and nonvolatile recording medium and in which data is written to and read from the recording mediums on the basis of a common file system, the recording medium (10) having a first data area, the nonvolatile recording medium (11) having a second data area and an identification information table to manage the first and second data area collectively. The device further includes an information selector (14) to select positional information including predetermined identification information on the basis of the identification information table, converter (15) to convert positional information selected by the information selector (14) into position information corresponding to the first data area or into positional information corresponding to the second data area, first writing unit to write data supplied from a host device to the first data area and a second writing unit to write data supplied to the host device to the second data area.
摘要:
A method of detecting a convexity present on a surface of a belt-shaped member (belt) or a roll-shaped member (roller), includes frictionizing (abrading) a surface of the member with a plate, and detecting at least one of (1) a vibration generated on the plate or (2) a change of pressure applied to the plate, to detect the convexity on the surface of the member.

A printing paper winding device for enabling winding of printing paper even paper with a base material having a low resistance to bending stresses or printing paper having RFID labels carrying IC chips. Bending stresses are reduced by dividing the movement region of the tension roller into four regions in order to enable the successive detection of the position or posture of the tension roller and by making the bending angle of the printing paper in the winding path close to a more obtuse angle. A winding control unit of the present invention determines whether the tension region where the tension roller is positioned is a first tension region, second tension region, third tension region, or fourth tension region, controls the drive unit to limit the tension roller to a tension region in which winding is possible in the direction such that the bending angle of the printing paper in the winding path, which follows the winding of the printing paper, is close to a more obtuse angle.

A tread (12) of a tire (10) has a two-layer structure. The tread (12) includes a base layer (23) provided on an inside in a radial direction and a cap layer (24) provided on an outside in the radial direction. The outer peripheral surface of the cap layer (24) constitutes a tread surface (17). The tread surface (17) is provided with a groove (18). A plurality of circular land portions (21) is formed by the adjacent grooves (18). The base layer (23) is provided with a convex portion (26) extended in a circumferential direction. A plurality of convex portions (26) is arranged in an axial direction. A height (h1) of the convex portion (26) is set to be 15% to 50% of a depth (d1) of the groove (18). A position (a dimension Δh) of a base bottom portion (29) of the base layer (23) based on an inner bottom portion (28) of the groove (18) is set at 1.6 mm or less from the inner bottom portion (28) of the groove (18).

A vehicle tire provided with a protective film which covers a surface of the tire is disclosed, wherein the protective film is indicative of at least one of tire data including tire conicity and radial force variation of the tire and can be washed away with water. Also a method of fitting tires on a vehicle is disclosed, wherein the installing positions of the tires are determined according to the data indicated by the protective film, and thereafter the protective film is washed away with water.
摘要:
In a method of making a pneumatic tire which comprises a tire main body and a tread rubber with axial edges, the inside diameter of the tread rubber being smaller at the axial edges than in the intermediate portion, the tire main body including an underlying component on which the axial edge of the tread rubber is stuck, the green tire is made by: making a raw tire main body including an underlying component; placing an annular raw tread rubber around the raw tire main body; swelling the raw tire main body by pressurizing the inside thereof; pushing the entire width of the raw tread rubber onto the swollen tire main body partially with respect to the tire circumferential direction; and conducting the circumferentially-partial pushing through the enter circumference of the raw tread rubber, whereby the axial edge of the raw tread rubber is stuck on the underlying component without being wrinkled.

A joint for piping includes a pipe with an annular swelling wall and a connector body with a socket that includes locking pieces. The locking pieces hold the annular swelling wall when the pipe is inserted through the connector body to connector the pipe to the connector body. A projected member on the pipe fits in a recess on the connector body to prevent rotation between the pipe and the connector body.
