  • Publication number: 20020104719
    Abstract: In a disk brake mounting apparatus wherein a knuckle 1 is provided with two disk brake mounting portions 2 and 3, and a disk brake 7 is fastened to the knuckle 1 with mounting bolts 5 and 6 passed through bolt-receiving holes provided in the mounting portions 2 and 3, respectively, the knuckle 1 is provided with a reinforcing connecting portion 15 formed by extending a body portion 10 of the knuckle 1. The reinforcing connecting portion 15 has its edge E1 extended radially outward in the radial direction of a rotor R with respect to a line L connecting the bolt-receiving holes of the two mounting portions 2 and 3. Thus, the torsional rigidity of the two mounting portions 2 and 3 is increased by the reinforcing connecting portion 15 to suppress vibrations in the opposite-phase mode in the rotor axial direction, thereby reducing low-frequency brake noise.

  • Patent number: 5920893
    Abstract: A storage control enables data on various storage media to be shared among host computers having various different host computer input/output interfaces. A control processor checks a host computer interface management table when write is requested by a host computer (HCP). The control processor writes write data in a cache slot of the cache memory without converting the format if the data format of the HCP is in an FBA format and it converts the format into the FBA format and writes it when the data format of HCP is in a CKD format. The processor checks a table when read is requested by HCP. If the data format of HCP is FBA, the processor transfers the read data read from the cache slot without converting it and if it is CKD, the processor converts the format into the FBA format and transfers the format converted data. The control processors, retrieve write data in the cache memory and writes it in a drive.

  • Patent number: 5775362
    Abstract: A fuel-effusion prevention valve includes a first housing member having an evaporation passage, a first engaging portion and a first cylindrical portion, and a second housing member having a partition portion, a communicating passage, a second engaging portion and a second cylindrical portion. The first cylindrical portion is formed so as to extend axially from the first engaging portion, and its diameter is smaller than that of the second engaging portion. The second cylindrical portion is formed so as to extend axially from the second engaging portion. A floating valve is disposed in a chamber so as to be able to open and close the valve hole in response to its buoyancy due to fuel flowing into the second chamber through the communicating passage. The first cylindrical portion is fused with the second cylindrical portion. A circular seal member is fitted into an installation hole formed on the fuel tank and its inner hole is fitted onto the outer circumferential surface of the first cylindrical portion.

  • Patent number: 5740194
    Abstract: A laser system is provided with a plurality of light emitting diodes arranged to energize the laser source. The individual diodes have separate controls so that they may be turned on separately from one another for different periods of time and to produce different amounts of illumination. A controller such as a CPU may be programmed to actuate the controllers in a desired manner to achieve to a controlled light profile upgrading versatility and accuracy of laser systems. In addition to sequencing individual light emitting diodes in various combinations, the diodes may be energized simultaneously in various combinations. A first combination may be illuminated for a relatively long time and a second combination energized to overlap part or all of the period of that first combination, or even to extend beyond the period of the first. Thus, in addition to adjusting pulse width time, time spacing between pulses and overlap of pulses may be adjusted as well as light amplitude of individual diode light sources.

  • Patent number: 5615754
    Abstract: A disc brake having a plurality of pistons with the same outer diameter fitted in a cylinder portion of a caliper on at least one side of a disc so that the pistons cause a pad to press against the disc. At least one of the pistons has a relatively large wall thickness so that it is different from the other pistons in pad pressing area, and its natural frequency falls outside the range of from 20 Hz to 20 kHz, thereby suppressing the generation of brake noise.

  • Patent number: 5299663
    Abstract: The disk brake includes a caliper having a plurality of claw portions. A carrier supports the caliper for sliding movement in a direction parallel to the axis of rotation of the disk. A pair of pads are disposed on opposite sides of the disk for sliding in the axial direction of the disk. A wear alarm member is attached to one of the pads, which is pressed by the claw portions of the caliper, at a position inbetween the claw portions. The wear alarm member has a mounting portion attached to the pad and a vibrating piece extending from the mounting portion in a direction intersecting the radial direction of the disk. The distal end portion of the vibrating piece is bent toward the disk at the periphery of the pad to form a contact portion.

  • Patent number: 5249647
    Abstract: A disk brake for a vehicle, for example, an automobile, is provided with a return spring to prevent dragging of pads by a disk when the brake is released. The disk brake has a carrier secured to a non-rotating part of a vehicle, a pair of friction pads supported by the carrier at respective positions which face each other across a disk, a pair of pad guides for slidably guiding the friction pads, a caliper supported by the carrier to press the pair of friction pads against the disk, and a linear return spring retained at both end portions thereof by the pair of friction pads, respectively, to bias the friction pads away from the disk. The return spring is bent radially of the disk at an intermediate portion thereof to form a single bent portion which is retained at the inward end thereof by a hook that is formed on the pad guide.
