摘要： Recirculation hot water system including a fluid delivery system used to supply potable water throughout a home or other facility, having a hot water supply pipe, a cold water supply/return pipe, a hot water heater, a pump, a manifold, a control system, a hot water and cold water faucet or valve, and a demand site (typically a sink or wash basin). The manifold further includes a thermostatic actuator and a check valve. The control means further includes a sending unit, installed in close proximity to the demand site, and a receiving unit, installed in close proximity to the heater. Command signals are transferred, from the sending unit to the receiving unit, via modulated signals that pass through the AC power lines that are used to distribute power throughout the home or facility. The main potable water supply is bifurcated into the hot water and cold water supply pipes with the heater installed in the hot water supply pipe upstream of the manifold, and the pump installed between the heater and the manifold and in close proximity to the heater. The hot and cold water supply pipes are in fluid communication with separate inlets to the manifold. An outlet from the manifold is in fluid communication with a cold water valve, while another outlet from the manifold is in fluid communication with a hot water valve. The manifold is internally ported such that the hot and cold water supply pipes are in fluid communication with each other.

摘要： A positioning system for a magnetic disk storage system. A first and second lead screw connected to their respective stepper motors are mechanically connected by a lever arm that adds these motions. The first stepper motor is controlled by an open loop control circuit and the second stepper motor is controlled by a closed loop circuit that reads servo information off the magnetic disk. The head is constantly repositioned to follow track eccentricities and can accurately read very closely spaced tracks on non-rigid disks.

摘要： A removable cartridge for a disk drive where the cartridge has a housing, a disk contained within the housing and a mechanism for reducing the rattling of the disk when the cartridge is not inside the disk drive and for permitting the free rotation of the disk when the cartridge is inside the disk drive. The rattle-reduction mechanism includes an inclined surface defined in the housing and a member having a first portion and a second portion. The interaction between the second portion of the member and the inclined surface of the housing may cause the first portion of the member to move into and out of contact with the hub. The contact between the first portion and the hub reduces the tendency of the disk to rattle. In one example embodiment, the cartridge has a housing with cartridge nut threads and a cartridge screw with cartridge screw threads. In this embodiment, interaction between the cartridge nut and the cartridge screw threads may cause a portion of the cartridge screw to move into and out of contact with a flange of the hub. A structure in the disk drive causes the cartridge screw to rotate in a manner such that the interaction between the cartridge screw threads and cartridge nut threads causes the cartridge screw to move away from and no longer contact the hub.

摘要： A magnetic head assembly and the method of manufacture therefor comprising a generally cylindrical housing having a tapered portion at one end thereof terminating in a circular aperture having an inner diameter, a circular slider body having an outer diameter slightly less than the inner diameter, a media engaging surface and an internal surface and being disposed within the circular aperture and affixed to the housing. The body also includes a first elongated slot disposed along a first diameter and extending through the body, a second slot disposed along a second diameter normal to the first diameter and extending into the body from the internal surface, and a central aperture extending through the body at the intersection of the first and second slots. A read/write transducer has a pair of read/write pole pieces which are separated to provide a read/write gap and which extend into the first slot with the read/write gap positioned with the central aperture. An erase transducer including a pair of erase pole pieces is disposed in the second slot with one-pole piece on each side of the first slot. The ends of the erase pole pieces nearest the read/write pole piece extend into the central aperture and are separated from the read/write pde pieces to form first and second erase gaps.

摘要： A cartridge adapted to be inserted into a disk drive where the disk drive includes a read/write head and a finger for engaging the cartridge. The cartridge includes a housing defining a cartridge door port and a door control port, a rotatable media within the housing, a door that rotates about a pivot point between a closed position and an open position, a portion of the door blocking access to the rotatable media through the cartridge door port when the door is closed, and a door opening link having a first end and a second end, the first end being coupled to the door closer to the pivot point of the door than to the portion of the door that blocks the cartridge door port, the second end being movable between a closed location and an open location. The door is in the closed position when the second end of the door opening link is in the closed location, and the door is in the open position when the second end of the door opening link is in the open location. The door control port is adapted to permit the finger of the disk drive to extend through the door control port and push the second end of the door opening link from the closed location to the open location as the cartridge is inserted into the drive.

摘要： A disk drive (30) conforms to the 1.8 inch form factor through of use of, for example, a removable cartridge (200) which has a disk (220) mounted on the hub (226) which hub (226) is manipulatable by a multifunction handle (58) of the disk drive (30), allowing the hub (226) to be seated on the spindle motor nose (56) of the disk drive (30). The multifunction handle (58) of the drive (30) provides for a compact, high capacity design by performing cartridge hub seating operations, cartridge ejection operations, head arm assembly unlocking operations, and handle locking and unlocking operations to ensure proper operation of the disk drive (30). The disk drive (30) includes an inventive ramp (66) design which allows the head arm assembly (64) to be initially received within the cartridge (200) as the cartridge (200) is inserted into its final registration position in the disk drive receiving mechanism (53) and to be more tangent with respect to the disk (220).

摘要： A removable cartridge 200 for a disk drive 30 which has a 1.8 inch form factor, has multifunction features which allow for high data storage capacity at a reduced size. The cartridge 200 includes a cartridge screw 206 which engages the cartridge nut 221 defined in the cartridge housing base 204 for allowing the disk 220 in the cartridge 200 to be positioned relative to the cartridge housing base 204 in order to successfully engage the spindle motor nose 56 of a disk drive 30. The cartridge screw 206 additionally prevents the disk 220 from rattling within the cartridge 200 whether the cartridge 200 is removed from the disk drive 30. The cartridge 200 further includes a multiplicity of projections 212, 214, 214, tang 208 and rails 216 which contact the drive 30 to perform the functions of proper reception and registration of the cartridge 200 in the cartridge receiving mechanism 53 of the disk drive 30 and proper operation of the cartridge 200 as the cartridge 200 is manipulated by the disk drive 30.

摘要： A pliant magnetic disc recording assembly having two adjacent transducer heads, with the center lines of the heads oriented at an angle to the axis of rotation of the magnetic disc and arcuately spaced with respect to such axis of rotation. The bearing surface of each head has a radius, and each bearing surface extends into the plane of the disc, whereby the disc has a wavy contour over the heads. The orientation, position and shape of the heads causes the disc to have a large wrap angle about each head whereby wear producing forces are distributed over a large area of the disc which lowers stresses on the disc.
