Patent JP-2698987-B2 (JP)
IPC: G11B5/596
Filed: 1988-10-13
Granted: 1998-01-19
Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data track and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.

Abstract: High melting temperature Pb/Sn 95/5 solder balls (18) are connected to copper pads on the bottom of a ceramic chip carrier substrate (10) by low melting temperature eutectic Pb/Sn solder. The connection is made by quick reflow to prevent dissolving Pb into the eutectic solder and raising its melting temperature. Then the module is placed on a fiberglass-epoxy circuit board with the solder balls on eutectic Pb/Sn solder bumps on copper pads of the board. The structure is reflowed to simultaneously melt the solder on both sides of the balls to allow each ball to center between the carrier pad and circuit board pad to form a more symmetric joint. This process results in structure that are more reliable under high temperature cycling. Also, to further improve reliability, the balls are made as large as the I/O spacing allows without bridging beam on balls; the two pads are about the same size with more solder on the smaller pad; the pads are at least 75% of the ball diameter; and the eutectic joints are made as large as possible without bridging between pads. For reliability at even higher temperature cycles or larger substrate sizes columns are used instead of balls.

Abstract: The present invention relates to an automatic clamping unit of the type having a spring loaded lock rod that is movable between an unlocked and locked position. A pair of locking balls are confined about the locking rod and are operative to move outwardly for engagement with the shank of a tool holder in response to the locking rod moving from the unlocked position to the locked position. The lock rod of the present invention includes a variable sloped ramp for engagement with each locking ball. As each locking ball moves along the variable sloped locking ramp, the mechanical advantage applied to the locking balls through the ramp varies due to the variation in slope. Each locking ramp is particularly configured such that the resultant locking load exerted by the locking balls against the shank of the tool holder is relatively constant although the position of the locking rod and the force being applied to the locking rod varies.

Abstract: 10-hydroxy 7-ethyl camptothecin (HECPT), an active metabolite of the camptothecin analog CPT-11, is poorly soluble in water. Because of its poor water solubility, HECPT has not been directly administered by parenteral or oral routes in human patients for the purpose of inhibiting the growth of cancer cells. There is also unpredictable interpatient variability in the metabolic production of HECPT from CPT-11 which limits the utility of CPT-11. This invention overcomes these limitations by teaching novel pharmaceutically acceptable lactone stable HECPT formulations for the direct administration of HECPT. The claimed invention also describes novel dosages, schedules, and routes of administration of the lactone stable HECPT formulations to patients with various forms of cancer.

Abstract: An improved version of a vibration isolation system using negative stiffness incorporates a payload (15) and payload platform(14) on just one 6 DOF isolator (12) in a unique and innovatively compact configuration. The isolator (1'2) includes a platform (14) supported on an assembly of independently acting flexure mechanisms which are connected in a serial fashion, tilt on top of horizontal on top of vertical, and in turn connected to a base (12). Proper arrangement of the mechanisms and the payload/platform centre of mass (17) provides highly effective decouple isolator performance. In addition, an innovative flexure preloading method which significantly improves vertical isolation performance is incorporated. This method can be used with prior (non-symmetric) designs or combined with a set of shear flexures (66) in an innovative symmetric arrangement to provide more assurance of ideal decouple response to mutually perpendicular base excitation input. Ageared mechanism (116) is also incorporated to facilitate manual adjustment of a main support spring (18) whenever payload weight is changed. <IMAGE>
