Title: Token passing type slotted loop network system with means for enabling high speed access control and simple frame slot stripping
Inventor: SHIMIZU HIROSHI
IPC: H04L12/433
Filed: 1990-06-11
Granted: 1993-12-21
Abstract: Abstract of the Disclosure:       In a token passing slotted loop network comprising a master station and a plurality of slave stations, a plurality of slots circulating through the loop and each of the slots having a fixed length and comprising a header portion and a data carrier portion, a particular one of the stations having the token transmitting its own data signal by use of one or more of the slots, the particular station transmits an end mark in the header of a particular one of the slots at an end of transmission of the own data signal and strips incoming slots from a start of the transmission of the own data signal until reception of the end mark circulated through the loop.  The particular station frees the token by inserting the token in the header of the particular slot.  The token can be inserted in the header of one of the slots after completion of the transmission.  Each of the slave stations writes into a priority request section in the header of each slot a particular priority request representative of a priority level of the own data signal when the own data signal occurs thereat.  The master station writes the highest one of the priority request into a priority section in the header of each-slot.  Each slave station detects the priority in the priority section and starts to acquire the token when the detected priority is lower than the particular priority request.

Title: Valve
Inventor: WILLIAMS GARY
IPC: F16K47/04
Filed: 1990-12-05
Granted: 1997-10-28
Abstract: A valve which is comprised of a body having an inlet passage and an outlet passage.  The inlet passage intersects the outlet passage at an angle.   The outlet passage has an annular  shoulder.   A plug  is  disposed within  the  outlet passage at the intersection of the inlet passage with the outlet passage.   The plug has sides with openings  thereby permitting fluids to flow from the inlet passage into  the outlet passage.   The plug is telescopically movable in the outlet  passage  between  a  first  position  and  a  second position. In the first position fluids flow from the inlet passage pass  through the openings into the outlet passage. The openings in the plug becoming increasingly restricted as the plug moves toward the second position.   In the second position the openings in the plug are totally obstructed by the outlet passage.   The sides of the plug have an annular flange extending outwardly.  The flange has a channel opening toward  the  outlet  passage.    A  seal  is  disposed  in  the channel.   When the plug is in the first position the seal means is sheltered from fluid flow within the channel.  When the plug is in the second position the seal in the channel engages the annular shoulder.

Title: High accuracy wheel examining method and apparatus
Inventor: HIRANO AKIRA
IPC: G01M17/06
Filed: 1991-02-12
Granted: 1996-11-05
Abstract: A method and apparatus for examining a wheel of a vehicle is provided.  A support roller assembly for supporting thereon the wheel rotatably is provided to be movable translationally as well as rotationally in a plane when unlocked.   A cylinder actuator having a reciprocating movable rod is also provided.  A wire is extended between the tip end of the rod and the support roller assembly.  When the rod is located at its advanced position, the wire is slackened to establish a static examination mode of operation,  in which the support roller assembly can move freely in a plane without constraints.   Under  this  condition,  the  static characteristic of the wheel is measured and adjusted, if necessary.  On the other hand, when the rod is located at its retracted position, the wire is under tension, and the cylinder actuator is operatively coupled to the support  roller  assembly  whose  movement  is  under constraints  through  the  wire.   Thus,  a  dynamic examination mode of operation is established.  Under this condition, the wheel is set in rotation and the dynamic characteristic of the wheel is measured and adjusted, if necessary.

Granted: 2003-04-08
Abstract: The present invention relates to a valve assembly (10) which is mounted on a part (piston unit 40) of an air motor (10) arranged for reciprocating movement in a housing (cylinder 12). The valve assembly includes a first valve unit (50), which is mounted on one side of the part (40), and a second valve unit (70), which is mounted on the other side of the part (40). The second valve unit is connected to the first valve unit (50) by means of the part (40) for common movement with the first valve unit relative to the part (40) when the valve assembly is switched as the part (40) reaches one of its two end turning-positions. In order to enable the valve assembly to be switched instantaneously and to eliminate the risk that switching the assembly will not take place, particularly when the motor is operated at a low speed, it is proposed in accordance with the invention, among other things, that each of the valve units (50 and 70 respectively) is produced from an elastomeric material and is provided with integrally formed spring elements (52 and 72 respectively) which will strike against solid abutments (18, 22) in the housing (12) upon mechanical switching of the valve assembly.

Title: Digital quadrature phase detection circuit
Inventor: ICHIHARA MASAKI
IPC: H04L27/22
Filed: 1991-11-22
Granted: 1996-03-05
Abstract: An analog angle modulated signal  is converted into a digital  signal  within an A/D converter using a  sampling clock having a frequency an integer times higher than the carrier of the angle modulated signal.  The digital signal is delayed by one sampling slot within each of the delay circuits  connected  in  series  to  the  A/D converter.  The output of the A/D converter and that of the fourth delay circuit from the A/D converter are multiplied by -1/2 within the respective digital weighting circuits, respectively, and the multiplied outputs as well as the output of the second delay circuit from the A/D converter are added together to generate an  I component  level  signal.  The output of  the first  delay  circuit  is  multiplied by -1  within another weighting circuit and this multiplied output as well as the output of  the third delay circuit are added together to generate a Q component level signal.

Title: Orthosis with joint distraction
Inventor: BONUTTI PETER M
IPC: A61F5/01
Filed: 1992-04-15
Granted: 1997-05-06
Abstract: An orthosis for extension and flexion of a joint of a limb provides for distraction of the joint upon extension. In one embodiment, a spreading arrangement positively moves the orthosis arms longitudinally outwardly relative to each other upon rotation from a flexed position to an extended position. In another embodiment, the axis of rotation of the orthosis arms is located outwardly from the axis of rotation of the limb. Upon rotation of the arms relative to each other from a flexed position to an extended position, the orthosis arms move longitudinally outwardly because of the geometry of the orthosis. Because the cuffs on the arms are clamped to the limb segments, the limb segments are also forced outwardly, providing joint distraction. Structure is provided for limiting the amount of joint distraction and avoiding injury to the joint.    The inner ends of the orthosis arms are linked together to maintain them in position relative to each other. The cuffs which attach the arms to the limb segments are adjustable longitudinally along the arms, to provide for different positions of the cuffs on the on limb, different length limbs, and the use of the orthosis on either a knee joint or an elbow joint.
