According to the invention, a cage has a ring portion, and a plurality of column portions that protrude from the ring portion, are arranged in the circumference direction, and form pockets that house balls serving as rolling elements. Each column portion has a column portion radially inward section that forms a bearing-radial-direction inward side portion of the column portion, and a column portion radially outward section that is connected to the column portion radially inward section at its radially outer end position, so as to protrude on both sides in the circumferential direction from the column portion radially inward section. An inner surface of each pocket is formed in a spherical shape that lies astride the column portion radially inward section and the column portion radially outward section. A connection position at which the column portion radially outward section is connected to the column portion radially inward section is adjusted to a position radially outward of a pitch circle position of the plurality of the balls that are held in the respective pockets. Thus, the thickness of the column portion radially inward section at the connection position is larger than the thickness of the column portion radially inward section at the pitch circle position.

An object of the present invention is to enable performing height recognition processing by setting a height of an arbitrary plane to zero for convenience of the recognition processing. A parameter for three-dimensional measurement is calculated and registered through calibration and, thereafter, an image pickup with a stereo camera is performed on a plane desired to be recognized as having a height of zero in actual recognition processing. Further, three-dimensional measurement using the registered parameter is performed on characteristic patterns (marks m1, m2 and m3) included in this plane. Three or more three-dimensional coordinates are obtained through this measurement and, then, a calculation equation expressing a plane including these coordinates is derived. Further, based on a positional relationship between a plane defined as having a height of zero through the calibration and the plane expressed by the calculation equation, a transformation parameter (a homogeneous transformation matrix) for displacing points in the former plane into the latter plane is determined, and the registered parameter is changed using the transformation parameter.

[Problems] A bearing assembly is provided which is designed to prevent a core (metal annular member), used in a synthetic-resin cover, from disengaging from the cover.[Means for Solving Problems] A bearing assembly H includes: a synthetic-resin cover 25 fitted in an inside surface of a vehicular-inner-side end of an outer ring member 2, and a metal annular member 33 disposed on an inside surface of a fitting engagement portion 26 of the cover 25, the fitting engagement portion being fitted in the inside surface of the outer ring member 2. The annular member 33 includes an engaging portion 33a in engagement with the cover 25.

A thrust ball bearing includes an upper case and a lower case. In the upper case and the lower case, annular rings which are formed in the upper case and the lower case, respectively support balls which are rolling elements, and inter-case gaps are formed between the upper case and the lower case in order to reduce sliding resistance and rotational torque. A seal unit is formed on an inner circumferential surface of the lower case. The seal unit is made up of a recess portion which is formed on the inner circumferential surface and a rubber elastic element which is made as a separate element from the lower case and is then fitted in the recess portion. The recess portion is formed into an annular shape along a circumferential direction of the inner circumferential surface.

A net made of material containing at least metal is bonded to a protector of a loud speaker, and hence shields electromagnetic waves. Electromagnetic interference can be prevented in an electronic apparatus such as a portable phone employing the loud speaker.
摘要:
An edge (29) for supporting a diaphragm assembly (100) with respect to a frame (26) is bonded to the frame (26) along the outer periphery thereof and joined to a diaphragm (27) in a position more peripherally inward than a voice coil (28) along the inner periphery thereof. The edge (29) partly overlaps diaphragm (27). This structure allows downsizing of the speaker, without reducing the sizes of a permanent magnet (21) and the edge (29).

Electro-acoustic converter (35) such as a speaker includes frame (26) attached to magnetic circuit member (24), diaphragm (27) attached to frame (26), voice coil (28) attached to this diaphragm (27) and having a part of which disposed in magnetic gap (25) in magnetic circuit member (24), terminal (30) made by bending a metal plate and being brought into contact with a power supply unit of an electronic device in which electro-acoustic converter (35) is installed by utilizing a spring pressure of this metal plate, and stopper (29) restricting bending of the metal plate forming this terminal (30) within a reversible limit of its metal material.
摘要:
A semiconductor device has an electrode pad, a capacitor and a substrate. The substrate has a given area on which the electrode pad and the capacitor are arranged. The electrode pad and the capacitor are arranged on the substrate so that each of at least two sides of the capacitor and each of at least two sides of the electrode pad is adjacent to each other at a given interval. The capacitor has a connecting side that connects the two sides of the capacitor and faces to the electrode pad. Outside angles of the capacitor formed by the connecting side and the two sides of the capacitor are more than 90 degrees.
