Title: Coated belt for belt-driven tape cartridge
Inventor: SMITH DAVID PHILLIP
IPC: G11B23/087
Filed: 1993-05-21
Abstract: A drive belt (18) for use in a tape cartridge (10) including a drive belt wound around a drive roller (20), two guide rollers (22, 24), and a tape pack (17). The belt has a coating (42) on the face of the belt that contacts the rollers. The coating includes carbon black and aluminum oxide particles dispersed in a polymeric binder. The coating on the belt is electrically conductive and has a resistivity of less than 400 ohm-cm. The coated belt minimizes wear on the rollers, voltage buildup, and electrical discharge within the cartridge. This reduces the number of transient errors that occur when reading and writing the tape (16). The tape cartridge may also include a metal pin (36) that contacts the coated face of the belt, thereby providing improved tape tension.

IPC: F16H7/12
Filed: 1994-11-25
Abstract: An auto-tensioner for applying tension to a transmission belt by a tension pulley and for damping reaction force acting from the belt. The tension pulley is rotatably supported to a lever member rotatably supported to a fixed pulley. A movable pulley is provided on the lever member at a position offset with respect to an axis of the tension pulley. An endless belt is wound between a circular friction surface of the fixed pulley and a circular friction surface of the movable pulley.          An initial tension applying spring forces to move the movable pulley outward, thereby applying initial tension to the belt.    When the movable pulley is moved by reaction force acting on the tension pulley from the transmission belt, damping force according to the reaction force is generated by grip generated between the belt and respective pulleys owing to change of tension between both spans of the belt.

Title: Track Seek Method and Device for Use with an Optical Information Recording and Reproducing Apparatus
Inventor: YAMAZAKI KOICHI
IPC: G11B21/08
Filed: 1994-12-02
Abstract: A  position  detector  (11,  12)  detects  a  relative position of an optical head (2) to a recording medium (1), and on the basis of the thus-detected relative position, a position detection signal (D) is generated in response to movement of a light beam (6) over a predetermined distance.          Then,  in response  to  the position detection  signal,  a comparison is made between the number (Na) of track crossing counted for the predetermined movement distance on the basis of reception of reflection of the light beam (6),  and a predetermined reference value (Nb)  for the predetermined movement distance.  Then, track crossing count compensation data (Nc) is generated which corresponds to a difference between  the  counted  number  of  track  crossing  and  the reference value, and the counted number of track crossing is corrected by use of such compensation data.

Patent CA-2149255-A1 (CA)
Title: Radiation detector
Inventor: OKUBO KAZUAKI
IPC: G01J5/12
Filed: 1995-05-12
Abstract: A radiation detector has a film-like pyroelectric element which has a fan shape, and two support plates which are made of an electrical and thermal insulating resin and adhered to the both ends elongating from the pivot of the fan shape to the peripheral portion.  After a radiation absorbing layer is attached to one face of the pyroelectric element, the resin plates are adhered to each other so that the layer is positioned inside and the pyroelectric element is formed into a conic shape, thereby forming a conic portion.  Radiation entering an opening of the bottom face of the conic portion is absorbed by the layer in the form of heat.  The temperature rise is converted by the pyroelectric element into an electric signal, thereby detecting the energy amount of the radiation.  A reflected component of radiation entering the layer again enters the layer.  Since the input radiation is repeatedly reflected and absorbed by the layer, the radiation is essentially 100% absorbed and detected irrespective of its wavelength.

Inventor: WEAVER EDMUND ALOYSIOUS JR
IPC: B65D43/02
Filed: 1995-07-18
Abstract: An end closure for reclosable packages and a method of manufacturing such an end closure.  The end closure is adapted for manual placement over an appropriately sized open package, container or box to substantially enclose the contents therein.  The end closure comprises a substantially rectangular resilient end wall having side walls extending down perpendic-ularly therefrom at each edge.  A thin, flexible, pleated sheet overlays the end wall and two opposing side walls.  The two sidewalls include expansion joints, and the pleat is substantially coincident with the expansion joints, permitting the end closure to open against a bias when manual pressure is appro-priately exerted.  The end closure, when held open, therefore fits easily over the package opening.  When the manual pressure is released, the end closure closes, forming a tight fit with the sides of the package, effectively protecting the food product from the environment.  An end closure in accordance with the disclosed invention may be employed in conjunction with a tear-strip package of substantially uniform cross-section to provide a space-efficient package with a reusable closure as the package is reduced in size.

IPC: A61B19/00
Filed: 1994-03-14
Abstract: The invention includes a rigid frame (18) that is positioned around the skull (12) to define a multidimensional coordinate system. Multiple arms (20, 22) are coupled to the frame, each arm having an attachment assembly (30) movable along a longitudinal axis directed toward the center of the rigid frame assembly. Multiple receptors (32) are either attached to the skull or drilled into the skull for receiving an associated attachment assembly.

Each arm has a multi-station receptacle (36) that receives various attachments used for mounting and attaching the receptors. Special bushings (54) are used to lock the attachment assembly in a preset longitudinal position in relation to the arm. The locked attachment assembly can then be removed from the arm allowing the frame to be removed from the skull while maintaining frame position information.

Title: Method and device for measuring characteristic magnitudes of a stream of fixed length data packets in a digital transmission system
Inventor: STOCK THOMAS
IPC: H04L12/56
Filed: 1995-11-02
Abstract: In digital transmission systems, adapted data units travel at a high throughput rate over large parts as a stream of fixed length data packets, called cells in this instance. The present method permits the measurement of characteristic magnitudes of the cell stream with respect to the respective individual connection to which they belong. It is based on storing from each arriving cell the identification data of the individual connection to which it is allocated, including its relative position in the cell stream. The memory is interrogated during a cell cycle time. A selection is made about which memory spaces within a defined area contain a predetermined identification data belonging to an individual connection. As a function of the selected memory spaces, the determined result, together with the magnitude and the position of the interrogated area, provides a decisive statement of the measured value. Several interrogations can take place within the same cell cycle time, and several measurement results can thereby be obtained. A preferred device for carrying out the method providesa shift register (15) as the memory, which stores the identification data (ai) at the clock rate of the arriving cells. In each cell cycle, a control circuit (16) determines which memory area must be interrogated about what data, which can take place in multiple form. It controls a selector (17), which tests the content of each shift register unit for coincidence with the specified identification data (ai), and establishes a signal bit (fi) if they coincide. An adder (19) calculates the sum m(aj) of all selected signal bits (fi).
