摘要:
A traffic management system manages, distributes, and controls various traveling states of vehicles at a high quality level. A vehicle-mounted unit performs an interconnection process for user authentication when entering a predetermined radio-wave zone. A radio unit disposed on a road sends interconnection process completion information to a center device when the interconnection process for connection to the vehicle is completed. If the vehicle does not connect to the radio unit after elapsed of a predicted time at which the vehicle is expected to travel across the radio unit, then the radio unit sends an overtime to the center device. The interconnection process completion information is received, the center device calculates a predicted time at which the vehicle is expected to pass across a radio unit, and sends the predicted time to the radio unit. When the overtime is received, the center device determines whether a fault has occurred or not. When it is judged that the fault has occurred, the center device sends alarm information to vehicles traveling near a site where the fault has occurred on the vehicle.

A recording disk is to be mounted on a hub. A base rotatably supports the hub through a bearing. A stator core is fixed to the base and includes an annular portion and a salient pole extending radially therefrom. A magnet faces the salient pole radially and is rotated with the hub. The magnet has a plurality of magnetic poles in the circumferential direction such that each of the plurality of magnetic poles faces the salient pole. The salient pole includes a rod-shaped body around which a wire is wound and a tooth portion that is provided radially outside the rod-shaped body and extends circumferentially. The circumferential end located at the end in the circumferential direction of the tooth portion is located radially inside a circumscribed circle passing through the tip located at the radially outermost end of the tooth portion.

A Dario communication system including base stations that distribute predetermined data by radio so as to be received by mobile terminals located within the communication area of a base station. This system comprises a management unit managing communication area information on the communication area of each of the base stations, a communication area information providing server to which the communication area information is sent from each of the base stations a mobile terminal that has, a radio communication unit for receiving communication area information sent from each of the base stations depending on the position of the mobile terminal and boots up an application program to be used in the communication area which the mobile terminal approaches according to this received communication area information.
摘要:
In a disk drive device, a magnetic recording disk is to be mounted on a hub. A base plate rotatably supports the hub through a bearing unit. A projecting portion is formed on the upper surface of the base plate having a cylindrical side surface centered along the rotational axis of the motor. A laminated core is formed by laminating magnetic steel sheets and has a ring portion and a plurality of teeth radially extending from the ring portion. The disk drive device has a tubular vibration-deadening ring. The outer surface of the vibration-deadening ring is press-fitted into the ring portion at least at a position, along the motor's rotational axis, closer to the upper surface than to the lower surface of the laminated core; and the inner surface of the vibration-deadening ring is fixed to the side surface of the projecting portion.

A suction ring is fixed to a motor base and is provided with an outer circumferential section having a first outer diameter that is smaller than an inner diameter of a wall section of the motor base. A plurality of protruded sections each have a second outer diameter larger than the inner diameter of the wall section of the motor base and protrudes outward in a radial direction from the outer circumferential section of the suction ring. The plurality of protruded sections of the suction ring are press fitted into a wall section of the motor base and secures the suction ring to the motor base. One surface of the suction ring coincides with a bottom surface of the ring magnet covering a whole range of a projected area of the ring magnet that is projected onto the surface of the suction ring.

A motor (50) is composed of a rotor (R) having a hub (2) and a ring magnet (8) that is fixed to the hub (2) and a stator (S) having a motor base (5) and a suction ring (11) in an annular shape that is made from a magnetic material and fixed to the motor base (5). The rotor (R) is sustained rotatable freely with respect to the stator (S) through a bearing (SB1, RB11, RB12), which is composed of a sleeve (10) and a shaft (13) that is inserted into the sleeve (10). The suction ring (11) is provided with a plurality of protruded sections (11a) that protrude in a radial direction on an outer circumferential section or an inner circumferential section of the suction ring (11). The protruded sections (11a) of the suction ring (11) are press fitted into a wall section (5e) that is provided on the motor base (5) and resulting in fixing the suction ring (11) to the motor base (5). One surface of the suction ring (11) is disposed so as to coincide with a bottom surface (8a) of the ring magnet (8) with covering a whole range of a projected area (T) of the ring magnet (8) that is projected on the surface of the suction ring (11).
摘要:
A process for fusion-bonding of resins, which comprises applying a layer of thermoplastic resin having a light transmittance lower than 20% and a melting point of 40.degree. to 250.degree. C. to a substrate and fusion-bonding the resin layer to the substrate by emission energy of a flash discharge lamp. The electric input energy J (joule) of the flash discharge lamp is controlled relative to the weight of the resin layer.

A disk drive device is provided with a recording disk, a base member, a bearing unit, and a hub member. In a marking step, unbalance information indicating the displacement of the center of gravity of the hub member with respect to the rotation center of the hub member is acquired, and an information mark containing the unbalance information is applied to at least the hub member or the base member. In an installing and adjustment step, the unbalance information is read form the information mark, and the position for installing the recording disk in an outer cylinder part is determined in accordance with the unbalance information so as to install the recording disk on the hub member.
