Title: X-ray lithography mask and devices made therewith
IPC: G03F1/22
Filed: 1990-03-28
Abstract: X-RAY LITHOGRAPHY MASK AND DEVICES MADE THEREWITH Abstract A mask for X-ray lithography is produced by initially forming a thin layer of polycrystalline silicon on a silicon oxide containing substrate. A portion of the substrate at the periphery of the major surface opposite the silicon layer is masked. The exposed portion of the substrate is removed by an etchant that is selective for silicon oxide containing composition relative to silicon, e.g. aqueous HF. The resulting membrane of silicon on a peripheral region of silicon oxide containing composition is in tensile stress as required for lithography, but is robust. Metal, X-ray absorbing patterns are formed on the silicon by standard lithographic procedures.

Abstract: The fascia stapler has a pistol-shaped housing from which two-piece clips can be ejected for closing an incision.          The retainers for the clips and the straps for the clips are held in respective cartridges within the nose of the housing and can be ejected individually upon actuation of the stapler.          A pusher assembly within the housing causes an individual strap to be expelled for passage through one end of a strap, piercing through the tissue and securement in the other end of the strap.  Approximators with tissue engaging teeth are also used to bunch up the tissue about the incision during a stapling operation.

Title: Multi-length packet format including check sequence(s)
Inventor: MAY CARL J JR
IPC: H04L12/70
Filed: 1990-04-25
Abstract: MULTI-LENGTH PACKET FORMAT INCLUDING           CHECK SEQUENCE(S) Abstract A unique packet transport word, i.e., header, format is disclosed which is advantageously employed to delimit the corresponding packet and to verify data fields in the transport word. An at least first parity check is employed in conjunction with a packet length indicator to delimit the corresponding packet. The at least first parity check is formed by computing a predetermined number of parity check bits from bits in predetermined bit positions of the transport word. These parity check bits are inserted into predetermined bit positions in the transport word. Similarly, bits representing the packet length indicator are also inserted into predetermined bit positions of the transport word. In a specific embodiment, a plurality of parity checks is employed to achieve increased robustness. The plurality of parity checks is formed such that each of the bits in predetermined bit positions of the transport word is used in computing at least two different parity check bits. In one embodiment, a first prescribed parity check is formed by computing parity over bits from predetermined bit positions in one or more groups of bit positions in the transport word and a second prescribed parity check is formed by computing parity over bits from predetermined similar bit positions in the groups of bit positions in the transport word. In one example, the transport word includes a plurality of bytes, each of which includes a predetermined number of bit positions forming columns and rows. Parity check bits forming the first prescribed parity check are obtained by computing parity from bits in predetermined bit positions in the transport word columns and parity check bits forming the second prescribed parity check are obtained by computing parity from bits in predetermined bit positions in the transport word rows. In this example, the first and second parity checks are obtained by so-called "group" processing and are adequate to both delimit the packets and verify the transport word data fields. These verified fields include, among others, the packet length and necessary information for delivery and "billing" of the packet. (FIG. 5).

Abstract: ABSTRACT OF THE DISCLOSURE:             There is disclosed a device for the safe-keeping of a key, which device comprises a cylindrical lock of the tumbler type provided with a rotary barrel operable by the key and a bolt which is displaceable between a first and a second positions when the cylinder barrel is rotated by the operating key and has an extension which projects out of the lock housing. The lock is of the type where the key becomes captive in the barrel after insertion and rotation of the barrel for moving the bolt to the second position. The device further comprises, in combination with the cylindrical lock, a tube which is coaxial with the bolt and is located outwardly of the lock housing, the bolt extension being slidable in the tube. Finally, the tube and the bolt are formed with a plurality of sets of radial holes located so as to become aligned with one another when the bolt extension has been moved to the second position, to receive the shackles of padlocks. In use, the key is thus held captive in the barrel until all the padlocks are removed.

Abstract: Cross-linked antibody conjugates are described which have at least one interchain bridge containing a reporter or effector molecule. The bridge may be the residue of a homo- or heterofunctional cross-linking reagent, and is located away from the antigen binding domains of the antibody. The antibody conjugates have an enhanced binding capacity and in vivo have good blood clearance and, in the presence of a tumour high tumour: blood and tumour: bone ratios.

Title: Seat belt retractor
Inventor: FUJIMURA YOSHIICHI
IPC: B60R22/42
Filed: 1990-09-27
Abstract: ABSTRACT OF THE DISCLOSURE    A seat belt retractor 1 includes an actuating member 28, 29 for actuating seat belt locking means 5 when a seat belt 3 has been extracted fully or substantially fully, as a result of which the seat belt 3 is locked against extraction.  Accordingly, a large load from the seat belt 3 will not act upon the reel shaft 4 and therefore-the reel shaft 4 need not have that much rigidity.  This makes it possible to form the reel shaft 4 of a light-weight, inexpensive material such as resin.  In addition, forming the reel shaft of a light-weight material makes possible a reduction in the weight and manufacturing cost of the seat belt retractor 1.

Title: Method and apparatus for controlling the speed of a motor
Inventor: NAITOH HARUO
IPC: H02P29/40
Filed: 1991-10-01
Abstract: An apparatus is disclosed which controls the speed of a motor driving a load.  A speed controller finds the difference between a command speed value of the motor and a detected speed value of the motor and generates a command current value of the motor on the basis of the difference.  A current controller controls current in the motor on the basis of a difference between a command current value received from the speed controller and a detected current value.  A torque detector is mounted on the shaft, whereby the motor is connected to the load, for detecting torque acting on the shaft, and an adder adds the detected torque signal detected by the torque detector to the command current value received from the speed controller, the torque detection signal being a correction signal for controlling acceleration torque of the motor.

Abstract: Synchronization is maintained between a regional radio transmitter/receiver and a remote transmitter/receiver communicating across a TDMA channel by detecting time misalignment of communications from the remote transmitter/receiver to the regional transmitter/receiver, commanding the remote transmitter/receiver to adjust its transmission timing, and, until the remote transmitter/receiver has adjusted its transmission timing, looking for a synchronization pattern accompanying transmissions by the remoter transmitter/receiver during two discontinuous time intervals, one centered about a time of occurrence of the synchronization pattern before the command and another centered about an expected time of occurrence of the synchronization pattern in response to the command.      Effectively, what would otherwise be a disadvantageously wide tune window is split into two advantageously narrow time windows to avoid detection of false syncs. Fewer false syncs are detected; and speech quality is increased.
