Patent EP-0324859-A1 (EP)
Inventor: HORIE KIYOSHI
IPC: G11B7/0033
Filed: 1988-06-23
Abstract: An error signal generator circuit suitably adapted to a device for reading optical recording medium to control servo mechanism by utilizing error signals of focusing, tracking etc. The circuit comprises an error detecting means which produces error signal upon receipt of read signal; an abnormal condition detecting means which detects abnormal reading upon receipt of said read signal; a signal holding means which holds the output of said error detecting means just before said abnormal condition takes place during a period in which the output of said abnormal condition detecting means indicates the abnormal condition; and a switching means which, upon receipt of the output of said error detecting means and the output of said signal holding means, selectively produces the output of said holding means when the output of said abnormal condition detecting means indicates the abnormal condition, and selectively produces the output of said error detecting means when the output of said abnormal condition detecting means does not indicate abnormal condition. The data can be read out continuously without any problem even under the circumstances where dust and dirt on the optical recording medium would have prevented the conventional circuit from executing proper control operation such as focusing and tracking.

Title: Drive mechanism for powering intravascular blood pumps.
Inventor: MOISE JOHN C
IPC: A61M60/462
Filed: 1988-12-02
Abstract: A disposable, sterilizable cable drive unit for an intravascular blood pump includes a rotor enclosed in a fluid-tight enclosure which can be slipped into the stator of a drive motor. The unit is connectable to a constant-rate purge fluid supply and to a dual-lumen cable sheath. One lumen provides a sterile purge fluid path; the other carries the drive cable to the blood pump and provides a return path for a flushing fluid in which the cable is immersed. The flushing unit is derived from the purge fluid supply at a constant rate, and the rotor may also be immersed in it if desired. The unit is held in the drive motor by a manually operated detent, and the self-centering action of the rotor aligns it with the stator when the motor is energized. The motor is mounted on a gimbal so as to be alignable with the cable sheath at its point of insertion into the patient's vascular system, in order to prevent stresses on the patient and kinks in the cable sheath.
