Granted: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE     In a disk drive device comprising an optical head having a movable part including a lens for focusing a light spot on a track of an optical disk and a photodetector which receives the light reflected from the track and provides a photoelectric conversion signal, a head actuator moves the movable part in a radial direction of the optical disk when the optical head accesses the tracks of the optical disk, and a motion detection means receives the photoelectric conversion signal and outputs a track-traverse motion signal representing the track-traverse motion of the light spot.        An acceleration detecting means detects the acceleration of the head actuator.  A target velocity generating means generates a track-traversing target velocity determined by the output of acceleration detecting means and the photoelectric conversion signal.  A state-observer means receives the output signals from the acceleration detecting means and the motion detecting means, and outputs an estimated track-traverse velocity of the light spot.  A head actuator drive circuit controls the head actuator such that the estimated velocity coincides with the target velocity.

Granted: 1990-10-16
Abstract: ABSTRACT OF THE DISCLOSURE         A power steering system having an electric motor and including an input shaft fixed to a steering wheel, an output shaft coupled to the motor via a reduc-tion gear, and a torsion bar provided between the input and output shafts, the output shaft being rotatable by the resultant of a manual torque for rotating the wheel and the torque of the motor.  The system comprises a sensor for detecting the relative angular displacement between the input shaft and the output shaft, and a microcomputer having stored therein  the relationship between the relative angular displacement and the motor current target value for determining the direction of rotation of the motor and a motor current target value from the output of the sensor to produce outputs.  The relationship stored in the microcomputer is a nonlinear relationship wherein variations in the motor current target value with the relative angular displacement are small in the range of small relative angular displacements but are great in the range of great displacements.

Abstract: 8087.011 P-F                          ABSTRACT        An implantable axial flow blood pump maximizes the blood flow while minimizing the dimensions of the pump. By magnetically suspending a rotor of relatively small diameter coaxially in a cylindrical blood conduit of substantially larger inner diameter,  an adequate flow area through the pump is provided, and the need for bearings,  lubrication and seal purging fluid is eliminated.   This  is made possible by the use of neodymium-boron-iron  rotor  magnets  which  allow  a substantial gap between the static motor armature and the rotor.   The rotor is simultaneously torqued and maintained in a position coaxial with the blood conduit by individually varying the current in the armature windings while they are being commutated.  The position of the rotor axis is accurately sensed by placing magnetically permeable strips into opposite ends of the pump stator blades in such a manner that they transmit to Hall sensors variations in an annular magnetic field surrounding the rotor adjacent the ends of the pump stator blades.

Filed: 1988-04-28
Granted: 1992-05-19
Abstract: Abstract:    A power supply for a magnetron is provided with an inverter circuit and a high-tension transformer.  In order to shorten the time required from supplying power to the cathode of the magnetron to the arrival at the rated output at the start of oscillation, there is a mechanism for detecting the oscillation start time of the magnetron, such mechanism so controlling the operation that the rated output is reached immediately after the oscillation starts.  A winding on the high-tension transformer for detecting the output voltage can be used to detect the oscillation of the magnetron.

Abstract: FLOW RATE CONTROL SYSTEM     Abstract of the Disclosure A flow rate control system is disclosed for measurement of ink flow through an ink jet system.   The flow rate control system receives an error signal indicative of deviation of flow rate from a set value.   The system includes proportional (P), integral  (I)  and derivative (D) control to generate a control signal based on the magnitude and sign of the error signal.  The control signal is used to control the on-time of an ink make-up valve which adds make-up ink to the system as ink is needed to maintain satisfactory operation.  In a preferred embodiment, the PID controller has noise reduction capability through the use of clippers  and  low  pass  filters.    In  addition,  conditional summation may be employed to minimize  "hunting" at low error signal levels.
