Title: Method and apparatus for determining rotation of medium
Inventor: TAZARTES DANIEL A
IPC: G01C19/72
Filed: 1999-12-09
Abstract: PROBLEM TO BE SOLVED: To generate a pseudo-random bit sequence having improved statistical characteristics by guiding a feedback bit from each generated sequence of a P-sub-sequence, and modifying the P-sub-sequence by one or a plurality of modifier bits. SOLUTION: A feedback bit is determined from a content of a shift register of a pseudo-random sequence generator 3, and sent to an output line 7. The feedback bit is shifted in its content of a shift register by a clock signal of a clock 13, and inputted to the register through a data input line 11. Accordingly, a new bit of the pseudo-random bit sequence is outputted to an output line 5. When the content of the register is matched to a final sequence stored in a final sequence detector 15, a statistical controller 9 generates a final sequence alarm. The controller 9 is operated by a controller 17 to send a stored modified bit sequence to the register through the line 11.

Title: Optical fiber cord
Inventor: HONGO HITOYASU
IPC: G02B6/44
Filed: 1996-12-16
Abstract: PROBLEM TO BE SOLVED: To prevent tensile fibers constituting an optical fiber cord from being damaged even if these fibers rub against jigs tools or guides at the time of production of the optical fiber cord by adhering lubricants to the tensile org. fibers. SOLUTION: A resin-coated optical fiber (coated optical fiber) 1 is disposed at the center of the optical fiber cord and the tensile fibers 2 adhered with the lubricants A are disposed to enclose its circumference. Further, the fiber is coated with a sheath 3 consisting of PVC as an org. high-polymer sheath on its outermost layer. In such a case, the lubricants A are required to be adhered at >=0.3wt.% on the tensile fibers. In general, lubricants of a polyolefin system, for example, polyethylene oxide, paraffinic wax and polyether-base lubricants are preferably used as the lubricants A. At the time of production the optical fiber cord, the tensile fibers 2 come into contact with the jig tools and, therefore, the partial breakage of the tensile fiber filaments occurs but such breakage may be prevented by adhering the lubricants A.

Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To provide an occupant crash protection device for an automobile capable of compacting a car body dimension and suitably reducing occupant deceleration at a collision in a simple structure. SOLUTION: An apparent inertial mass of a car body at the initial time of the collision is reduced by supporting a weight member more or less forwardly movably at the collision, deceleration higher than an average deceleration is generated in the entire car body including a seat, a negative car body deceleration (acceleration) is temporarily generated on a movable part, namely, the seat by applying the inertial mass of the weight member to the movable part movable back and forth in relation to the car body, and finally the car body is integrally reduced in speed at the average deceleration. Therefore, a car body deceleration waveform preferable for reducing the occupant deceleration can be realized, and large reduction of the occupant deceleration can be achieved even for a car body deformation amount (dynamic stroke) smaller than the prior art.  This can be realized in a simple structure, so that the car body can be compacted.
