Abstract: A bearing device includes an oil supply body that cooperates with a bearing ring to form an oil retention space to be filled with a lubricating oil. The oil retention space is open at least on a rolling element side. Thus, the lubricating oil is supplied from the oil retention space to a rolling bearing.

Abstract: A particle size distribution measurement device includes a cell holding body 31 that holds a measurement cell 2 containing a measurement sample and a dispersion medium and a reference cell 6 containing a reference sample and is rotated by a motor 322, and a cell discrimination mechanism 7 that discriminates the cells 2, 6 passing through a predetermined rotation position by using a magnetic force or electrostatic capacitance.

Abstract: Provided is an electrophotographic belt of an endless shape including a substrate, wherein the substrate contains a polyimide resin and carbon nanotubes, wherein a content of the carbon nanotubes in the substrate is 15 vol % or less with respect to a total volume of the polyimide resin, wherein the substrate has a tensile strength of 200 MPa or more in each of a peripheral direction thereof and a direction perpendicular to the peripheral direction, and wherein the substrate has a thermal conductivity of 0.9 W/(m·K) or more in a thickness direction thereof.

Abstract: An information processing apparatus communicatively connected to a tape printing apparatus includes a tape width acquirer that acquires a tape width; a receiver that receives an instruction to print a print image; a calculator that calculates a margin length of a margin region of the tape measured in a tape width direction, the print region being where the print image is to be printed; a proportion determiner that determines whether or not the margin length is a particular proportion or above of the tape width; and a print controller that controls the tape printing apparatus to print a margin image when it is determined that the margin length is the particular proportion or above of the tape width, and controls the tape printing apparatus not to print the margin image when it is determined that the margin length is not the particular proportion or above of the tape width.

Abstract: A disk system miniaturized by sharing moving spaces of a disk clamper portion and a disk operating portion. The disk system includes a disk clamper portion (300) for holding a disk (R), the disk clamper portion (300) being provided in such a manner as to be movable substantially in parallel to a disk carrying path (102) on which the disk (R) is carried in a range from one end to the other end of the disk carrying path (102); and a disk operating portion (400) for rotating the disk (R), the disk operating portion (400) being provided in such a manner as to be movable substantially in parallel to the disk carrying path (102) in a range from one end to the other end of the disk carrying path (102).

Abstract: A disk system capable of sharing portions at which disks are disposed, thereby miniaturizing the entire structure of the system. The disk system includes a plurality of stockers for containing disks in such a manner as to substantially align rotational axial lines of the disks to each other. The disk system also includes a stocker moving mechanism for moving the stockers to specific positions. The disk system also includes a disk driving mechanism for rotating the disks contained in the stockers.

Abstract: A disk system miniaturized by sharing moving spaces of a disk damper portion and a disk operating portion. The disk system includes a disk damper portion (300) for holding a disk (R), the disk damper portion (300) being provided in such a manner as to be movable substantially in parallel to a disk carrying path (102) on which the disk (R) is carried in a range from one end to the other end of the disk carrying path (102); and a disk operating portion (400) for rotating the disk (R), the disk operating portion (400) being provided in such a manner as to be movable substantially in parallel to the disk carrying path (102) in a range from one end to the other end of the disk carrying path (102).

Abstract: A disk system capable of preventing a disk from being damaged. The disk system includes an upper disk roller (201) and a lower disk roller (202) provided at a disk insertion port of a housing (100), and a roller open cam plate (203) for adjusting a magnitude of a gap (d2, d3, d4) between the upper disk roller (201) and the lower disk roller (202).

Abstract: The construction of a vibration damping device includes a splined or generally spiral groove formed either in the outer periphery of a damper pin, which is inserted into a damper, or in the inner periphery of a hole formed in the damper for inserting the damper pin therein.

Abstract: Deck bases of conventional disk memory reproduction devices are fastened at four points by side lock pins protruding from the front and rear of the deck base and the side lock plates located opposite the side lock pins. This invention reduces the parts count and makes the deck base more compact by fixing the deck base at three points using side lock pins and side lock plates placed opposite them.

Abstract: In conventional disk shaped recording reproduction devices, vibrations have been absorbed by the up and down motion of protruding rods which are supported in a viscous liquid such as a silicon oil. According to this invention, an inexpensive elastic body is used, which is heated by a heater so that, by maintaining the temperature of the elastic body within a certain range, the deterioration of the vibration absorbing characteristics of the elastic body with temperature changes is considerably reduced and the elastic body can be made more compact.
