Patent EP-0322385-A2 (EP)
Inventor: DAVIE NEIL ROGER
IPC: G11B11/10
Filed: 1988-11-16
Abstract: A magneto-optical player employs a differential readback circuit. The differential signal output of the readback circuit is low pass filtered. The filtered signal is converted to a single-ended signal and applied to a field effect transistor (45) (FET). The FET is connected between one of the differential inputs of the readback circuit and a reference potential. The single-ended signal controls the FET to variably attenuate one side of the differential signal for reducing noise induced into the readback signal from diverse sources.

Abstract: An apparatus and method for testing an access time of a macro embedded in a LSI chip. The apparatus includes a logical gate connected to the output latches of the macro, thereby controlling the access time of the macro, and a test latch for determining an on-chip delay time between a test signal for enabling the output latches and an input signal for enabling the macro. The method includes the steps of determining the on-chip delay time between the test signal and the input signal, thereby allowing the test signal to be synchronized with the input signal, supplying the synchronized test signal to the output latches for a manufacturer specified macro access time, and testing the latched output data from the macro.

Abstract: Apparatus and methods for performing parity checking in an environment in which devices which perform parity checking (103) and those which do not (150) are connected to the same synchronous bus. The bus includes a parity enable line (113), which carries an parity enable signal indicating that the device transmitting data on the bus is a parity device which provides the parity of the data it transmits, a parity line (111), which carries the parity of the data being transmitted, and a parity error line (109) which carries a parity error signal indicating whether the receiving device detected a parity error. The data is transmitted in a first bus cycle, the parity enable signal and the parity are transmitted in the following bus cycle, and the receiving device transmits the parity error signal in the next bus cycle after that. The bus interface for each parity device includes a parity generator (327) and logic (519, 521, 523, 525, 509) which generates the parity and parity enable signals and receives the parity error signal when the parity device is transmitting and which receives the parity and parity enable signals and generates the parity error signal when the device is receiving. The apparatus is used with system diagnostic apparatus which records the occurrence of any parity error among devices attached to the bus.

Abstract: A device (10) for winding and unwinding a waterski tow-line (21) comprises a substantially enclosed housing (20) having a spool mounted for rotation in the housing. A driven gear is mounted on the spool (22) for rotational driving thereof. A drive shaft is journaled in the housing for rotation and for axial sliding relative to the housing and the drive shaft (28) has a first end portion protruding from the housing and a second end portion extending into the housing. A drive gear (26) is rigidly affixed to the drive shaft for rotation and for axial sliding with it. A spring (36) is mounted in the housing to bias the drive gear (34) into meshing engagement with the driven gear (26). A crank lever (38) is pivotally connected to the second end portion (32) of the drive shaft by an eccentrically positioned pivot pin (46). 
     With this arrangement, upon pivoting movement of the crank lever (38) to a first orientation generally transverse to the axle of the drive shaft (28), the yoke portion (48) urgingly contacts the housing so as to cause axial sliding of the drive shaft (28) in a first axial direction against biasing of the spring (36), so as to cause disengagement of the drive gear (34) from the driven gear (26), thereby allowing free rotation of the spool (22), and consequential unwinding of the tow-line therefrom. On pivoting movement of the crank lever to a second orientation 180° opposite to the first orientation, the yoke portion (48) is removed from urging contact with the housing (20) so as to allow the drive shaft (28) to slide in an axially opposite second   direction under biasing of the spring (36), so as to cause engagement of the drive gear (34) with the driven gear (26), thereby allowing for controlled rotation of the spool (22) upon rotation of the crank lever (38), so as to wind the tow-line (21) around the spool (22).

Abstract: A thin film adhesion apparatus includes a thin film feed member (10) with a suction surface having rows of transversely extending grooves therein. Each groove has suction holes (10c) for vacuum sucking a thin film (1B) to the suction surface of the feed member. Each row groove (10B) is discontinuous in the transverse direction and consists of groove sections which are strategically placed so that each standard width thin film will cover completely, and just barely, a set of groove sections, thereby insuring that no air gap will exist between thin film and groove sections and preventing wrinkling of the thin film.

Abstract: A driven clutch disk assembly adapted for use in a friction clutch includes a system for controlling clutch engagement friction, whereby an increasing surface contact friction area is presented in order to limit clutching capacity over an initial clutch engagement period. The result is a substantial reduction of the chatter which tends to occur in clutch systems which utilize metallic friction elements. In a preferred form, the clutch disk assembly incorporates a pair of circumferentially extending cantilevered spring beams (34), both positioned intermediately of a pair of plates (20), each spring beam (34) being loaded against one of the pair. An associated friction element (22) secured to the backing plate will thereby have a crowned surface for initial clutch engagement. The surface will collapse during engagement to ultimately present a full flattened friction surface area.

Abstract: An apparatus for controlling the ratio of the assisting force produced by a power steering system installed in an vehicle to the steering torque supplied by the driver wherein the ratio is changed by a solenoid valve (54) arranged in the power steering system. The CPU (50) of the apparatus changes control current to be applied to the solenoid valve (54) using a characteristic map defining change of a base current with respect to changes of the vehicle speed and the steering angle. Further, the CPU increases the control current, when the steering wheel is returned to its neutral angle position, so as to decrease the ratio, increasing the self returning ability of the steering mechanism. The control current applied to the solenoid valve during the returning operation is changed depending upon both steering angle and steering speed of the steering wheel using additional characteristic maps.
