Inventor: SUZUKI OSAMU
IPC: G11B23/04
Filed: 1991-10-16
Abstract: A magnetic tape cassette and a method of manufacturing the same. Components of the cassette are molded from a molding material composed of a resin and a pulverized metal dispersed therein. The pulverized metal is selected so as to have a melting temperature that is less than or equal to that of the resin. When the molding material is heated, the pulverized metal melts and randomly mixes with the resin. The resulting components yield a cassette that exhibits high vibration, shock, and temperature resistance.

Abstract: A collapsible framework constructed of rods pivotally joined at their ends to hubs to form a self-standing unit when expanded and to fold into a small set of nearly parallel rods when folded. The hubs are designed to pivotally join the ends of four rods, with the plane defined by the pivot axes of one pair of opposing rods being offset from the plane defined by the pivot axes of the other pair of opposed rods attached to the same hub. A stab-connection latch locks two hubs together and secures the framework in the expanded position. Folding channel bars are attached to knobs on vertically aligned hubs by key-slots, the key-slots of one channel bar being of progressively shorter length going from the top-most to the bottom-most of the vertically aligned hubs to which the bar is attached.

Abstract: There is disclosed a method of updating data stored in storage locations of a storage unit, in particular of a Flash EPROM. 
     The activity of updating data stored in some types of non-volatile storage units, such as Flash EPROMs, is time consuming. 
     A remarkable reduction in updating time is obtained by writing information relative to updating to be carried out in not occupied storage locations and executing the updating all at once on the storage locations containing the data.

Abstract: The arrangement comprises two electrically controllable cascaded interferometric modulators (15, 25), a directional coupler (19), a polarisation converter (29) and a coupler (34). The first modulator (15) follows the optical input (12) and is constructed for dividing and reassembling the incoming light beam (Pin). The directional coupler (19) again divides the reassembled light beam at a ratio of about 1:9. The stronger part-beam (p12) passes through the polarisation converter (29), the weaker part-beam (p22) passes through the second modulator (25). The coupler (34) recombines the two part-beams (p12, p22) and emits the modulated light beam (Pout) via the output (35). The drive unit (40) adjusts the arrangement (11) by means of four drive voltages (U15, U19, U25, U29) in such a manner that the phase shifts in the modulators -(1/3)f and, respectively, +(2/3)f and the polarisation directions of the part-beams (p12, p22) are orthogonal to one another. In this case, the modulation voltages (M15, M25) are identical for both modulators (15, 25) which results in very good suppression of third-order modulation distortion. <IMAGE>

Abstract: A magnetized or unmagnetized body (10) of a permanent magnet material is heated in a pattern by a laser beam (18) to a temperature sufficient to lower the magnetic coercivity of selected heated regions of the pattern and then exposed to a magnetic field to magnetize or to re-magnetize the selected heated regions. A pattern guide (30) is used in the process to densify the pattern. In the process, energy (18) is directed through the pattern guide (30) and onto the selected regions, whilst the pattern guide (30) prevents or minimizes heating of unselected portions of the body (10). Magnets so produced can have very high pole density, digital encoding and analog patterns having gradually varying local field strength.

Abstract: An aluminum layer formed over a semiconductor integrated circuit. A metal layer (22) is formed over the aluminum layer (16), and both are etched to define a conductive signal line. Another metal layer (26) is deposited and etched back to form a sidewall metal regions, so that the aluminum in the conductive signal line is surrounded on the top and sides. The metallic layer used to form the sidewall regions can be selectively deposited to minimize the amount of etchback required. In the resulting structure, the metal side and top layers contain the aluminum in the signal line, and therefore help prevent problems caused by aluminum electromigration.

Abstract: In the case of a position-controlled drive (A), zero point drift phenomena are automatically eliminated. To achieve this, the following error (SA<*>) to be expected is determined by means of a model (IV) and compared with the actual following error (SAist). During each stoppage detected by an observer (ZB), the following error difference feeds an integrator (14), the output of which feeds a speed precontrol path of the arrangement. Furthermore, the following is achieved: in the case of a position-controlled drive (A), non-conformities are automatically eliminated. To achieve this, the following error (SA<*>) to be expected is determined by means of a model (IV) and compared with the actual following error (SAist). During each virtually stationary speed status detected by an observer (ZB), the following error difference is weighted with the reciprocal of the desired speed (vsoll) and fed via an integration level (15, 16) preferably into a speed precontrol path of the arrangement. <IMAGE>

Abstract: A method and apparatus is disclosed for the instant intraoperative detection and biopsy of metastatic cancer using fluorescence spectroscopy. A photosensitizing agent selectively retained by cancerous tissue is administered prior to surgery. A fiberoptic probe (1) integrated with a biopsy device (2) illuminates the examined tissue and causes fluorescence which is recorded by a spectrograph and plotted as a spectral curve. The intensity ratio (S1/S2) for the fluorescence from the photosensitizing agent (S1) and autofluorescence (S2) for the examined tissue is compared with the intensity ratio at the same wavelengths for primary tumor and normal tissue. Tissue that displays an intensity ratio different from that of normal tissue can immediately be analyzed for the depth of tumor involvement and then excised for histological examination using the biopsy device.

Abstract: A method for reducing the apparent response time for write I/O operations initiated by a host system (147) to a RAID level 3, 4 or 5 disk array including a spare disk drive comprises the steps of (1) saving write data received by the disk array from the host system directly to the spare drive, (2) issuing a write complete status signal to the host system (147) indicating completion of the host write I/O operation, thus freeing the host processor to perform other functions, and (3) transferring the data saved to the spare drive to the active drives within the array. This third step may be executed at any convenient time following the second step. For example, in systems where a host processor functions as the array controller, this third step may be delayed while higher priority tasks are executed. In systems where the disk array includes an array controller, the array controller coordinates the execution of this third step with other controller or array operations to optimize array operation. In addition , the data from multiple write I/O opertions may be accumulated to the spare drive prior to the step of transferring the data saved to the spare drive to the other, active, drives within the array.
