Patent CA-2021688-A1 (CA)
Inventor: TANIGUCHI ATSUKI
IPC: H04L7/00
Filed: 1990-07-20
Abstract: ABSTRACT OF THE DISCLOSURE     A phase matching circuit for realizing accurate data transmission and reception through phase shift control only during a data invalid region.  The phase matching circuit includes an input buffer for taking first data with a first clock; an output buffer sending second data with a second clock; a phase detector for comparing the phases of first and second clock; and detecting a phase difference within a predetermined value; a phase control unit for directly outputting the first data to the output buffer when the phase difference within the predetermined value is not detected or for outputting the first data phase shifted to the output buffer, and for converting the first data synchronized with the first clock to the second data of the same content as the first data synchronized with the second clock in the same frequency as the first clock; an invalid data region detector for detecting an invalid region of first data; and a phase shifter controller for inhibiting phase shift control in the phase control unit when the invalid data region detector does not detect the invalid region and for allowing phase shift control in the phase control unit when the invalid data region detector detects the invalid region.

Title: Soil compactor
Inventor: POLEY CHARLES L
IPC: E01C19/41
Filed: 1991-05-17
Abstract: RBP File No. 5605-003 ABSTRACT OF THE DISCLOSURE         A soil compactor for use in compacting soil or other materials,  has full isolation of the operator's station from both front drum vibration and rear road shocks. The compactor contains a front frame articulately joined to a rear frame. The compactor also contains a subframe which supports an operator's  station,  motive power, and dual fuel/hydraulic oil tank. The subframe is mounted on rubber shocks to the rear frame.  The compactor is constructed with a rollover protection structure (ROPS) bolted to the subframe and mounted on isolation mounts to the rear frame. At the rear of the vehicle, a pair of isolation mounts are disposed between the vehicle's dual tank and the rear frame. This structure serves to isolate the operator's station from the drum vibration transmitted through the front frame as well as from the road shock and vibrations transmitted from the rear tires to the rear frame. The soil compactor contains a drum drive consisting of a hydraulic drum motor with splined shaft which is rotatable with the drum hub and a spindle. The spindle is located between the hub and the motor and surrounds the shaft of the motor. Cylindrical roller bearings are placed between the spindle and the hub to permit the hub and motor shaft to rotate with respect to the spindle, and to withstand vibration transmitted by the drums.

Title: Tracheal suction catheter
Inventor: RUSSO RONALD D
IPC: A61M1/00
Filed: 1992-01-10
Abstract: A suction catheter has a distal end portion with an opening for insertion into a patient's airway.          The proximal end portion is attached to a resilient tubular member on which an external valve  mechanism can operate to prevent fluid flow through the member.          The  valve  mechanism  is  biased  to  a normally closed condition, will open the tubular member when depressed, and will return to its normally closed condition when not depressed.  A downstream connector can be attached to  a  source  of  suction.    The  invention is  more comfortable for the patient, uses fewer components and is less expensive than prior art suction catheters.
