  • Patent number: 5012371
    Abstract: A limit stop/latching assembly in a disk storage system includes a crash stop for limiting travel of the actuator carriage at a fixed stop position. The assembly has a first abutment surface defining the stop position, a stop pin on the actuator carriage movable in a path by travel of the actuator carriage to abut the first abutment surface, and a latch having a second abutment surface which is movable between a free position out of the path of the stop pin and a latched position with the second abutment surface abuting the stop pin and facing the first abutment surface across the path to latch the stop pin at the stop position. Advantageously, the latch is mounted for movement around a first mounting pin in rotary travel having a center defined by the crash stop pin.

  • Patent number: 4644521
    Abstract: An optical disk cartridge has two opposed cartridge sections held together by four locking assemblies. Each locking assembly includes a first locking jamb attached to one section, a second locking jamb attached to the other section, a locking detent and a spring. The jambs can be locking fingers parallel to and adjacent to one another when the cartridge sections are joined, in which case the detent surrounds the fingers as a sleeve, preventing the fingers from moving apart. The spring biases the detent into locking engagement with the fingers, keeping the cartridge closed. Alternatively, the jambs can be aligned slots in the cartridge top and bottom sections, with each detent having a protrusion that enters its associated slots. The spring and most of the detent are contained inside the cartridge. However, each detent includes a leg extended outside the cartridge through an aperture in the cartridge side wall. Also disclosed is a drive apparatus for use with the cartridge.

  • Patent number: 4587466
    Abstract: A two axis linear motor for carrying the objective lens for optical focusing and optical tracking in an optical recording system has a stationary structure for providing a magnetic field and a moving armature structure. The stationary structure may have two permanent magnets and several pole pieces to properly shape the field with respect to the armature. In one embodiment, a central elongated pole piece and two parallel adjacent elongated pole pieces which are associated with two permanent magnets to form flux gaps with the central pole piece. Flux returns to the magnets through a lower pole piece to which the central pole piece is attached. The central and lower pole pieces have an aperture through which the laser beam may pass on its way to and from the objective lens.

  • Patent number: 4411443
    Abstract: The invention includes a low-drag cycle having an elongated frame extending between a smaller front wheel and a larger rear wheel. A cyclist assumes a recumbant position over the frame facing down. A cycle is steered by means of the front wheel, while the cyclist powers the cycle by means of a pedal arrangement driving the larger rear wheel. A streamlined, pod-shaped body which is symmetrical about an axis parallel to the direction of travel achieves a very low coefficient of drag and maximizes laminar flow to further reduce drag. The cycle wheels are contained within two streamlined fairings which extend from the streamlined cycle body to near the ground, the area between wheels being left open to increase the lateral stability of the cycle and to allow the rider to straddle the frame so that both feet may be placed on the ground while starting or stopping the cycle.

  • Patent number: 4363056
    Abstract: A housing (1-10) for a disk (1-12) used in a "Winchester"-type disk mass information storage unit in a data processing system. The housing is symmetrical about the plane of the disk, and supports the disk spindle (2-33) on both sides of the disk. The housing includes two substantially identical members (1-16, 17) fitted together in a clamshell-type arrangement. The housing includes a housing extension (1-26) for receiving and supporting the read/write heads (1-14) and actuator (1-15) therefor from both ends thereof. The members forming the housing are preferably thin walled castings, and may include fins (1-104) to dissipate heat or to enhance the housing's mechanical rigidity.
