Patent EP-0371274-A2 (EP)
Inventor: CHRISTENSEN NEAL TAYLOR
IPC: G06F11/10
Filed: 1989-11-03
Abstract: A method of handling errors in the C bit of a storage key by modifying the INSERT STORAGE KEY (ISK) and the RESET REFERENCE BIT (RRB) instructions. If an error is found in the C bit during the execution of these instructions, microcode is instructed to refresh the C bit. The C bit is interrogated a second time to determine if the refreshed C bit is still in error. If the refreshed C bit is not in error a second time, then the first error was caused by a soft or transient error, and the instruction is continued. If the refreshed C bit is in error a second time then the first and second errors were caused by a permanent error such as a stuck bit, and a system recovery machine check error is generated. The handling of C bit errors is thus done in a dynamic fashion as the instructions are executed.

Abstract: A workpiece manipulator assembly for a forging press having a press ram comprises a workpiece rotating mechanism including a rotary drive system for rotating a workpiece in peripheral direction. The rotary drive system is operated by a drive motor running at a preselected constant speed to rotate the workpiece about an axis of rotation. An arresting assembly stops the rotary movement of the workpiece before and during a pressure contact phase for the press ram. The rotary drive system is adapted to rotate a driven worm which produces rotary movement to the workpiece rotating means and is mounted for axial displacement. The arresting assembly includes an axial drive unit for predeterminably controlling axial displacement of the driven worm to effect the arresting of said rotary movement.

Abstract: The invention improves upon the diaphragm/beam-type transducers and method of manufacturing same described in U.S. Patent No. 4,368,575. 
     The new transducers and method of manufacture utilize strips or slivers of silicon or germanium which are larger than the individual strips used in the apparatus and method described in U.S. Patent No. 4,368,575 by an amount sufficient to permit (a) the formation of two gages on each strip and (b) the forming of bonding pads on each gage. The bonding pads are formed on the gage strip before the strip is bonded to the beam, so that formation of the bonding pads and bonding of the strip to the beam can be handled automatically. The strips are mounted to one side of the midpoint of the beams, so that when a diaphragm/beam is deflected by application of a fluid pressure, one of the two gages will undergo a tension strain while the other gage will undergo a compression strain. Because both gages form part of the same silicon or germanium strip, they tend to be virtually identical in physical and electrical properties, thereby simplifying calibration of the resulting transducers.

Abstract: The disclosure relates to a pivot bearing assembly (52) for a disc drive comprising in combination a bearing (52) surrounded on one side by a wishbone-shaped end (60) of the actuator arm (38), and on the other side by a biasing spring metal strip (70) whose ends are tightly attached to the split ends (62, 64) of the wishbone of the actuator arm. When the arm assembly is mounted in the disc drive, the bearing is mounted on its center of rotation, with the spring tensile force biasing the head of the actuator arm against the spindle (42) of the stepper motor (37). By providing the distal end of the actuator arm with a gear sector (56) having gear teeth on its face which mesh with a pinion (54) on the motor shaft (42) of the stepper motor (37), rotation of the motor shaft across the face of the gear sector causes movement of the actuator arm (38) and with it the flexure (36) and transducer (34), across the surface of the disc (30). The head arm (44) supporting the flexure and transducer extends from the side of the actuator drive arm (38) at a point near the stepper motor (37) driven end of the drive arm, reducing head arm length.

The developer material is transferred at the other end by gravity feed back to the first auger.

Abstract: The characteristics of a biological fluid sample having an analyte are determined from a model constructed from plural known biological fluid samples. The model is a function of the concentration of materials in the known fluid samples as a function of absorption of wideband infrared energy. The wideband infrared energy is coupled to the analyte containing sample so there is differential absorption of the infrared energy as a function of the wavelength of the wideband infrared energy incident on the analyte containing sample. The differential absorption causes intensity variations of the infrared energy incident on the analyte containing sample as a function of sample wavelength of the energy, and concentration of the unknown analyte is determined from the thus-derived intensity variations of the infrared energy as a function of wavelength from the model absorption versus wavelength function.

Abstract: An interpolator, particularly for use with an optical grating for detecting position in a metrological apparatus, receives input signals in quadrature. One of the input signals is squared and the two signals are multiplied together to provide further signals in quadrature at twice the frequency of the input signals. One of the further signals is also squared and the further signals are multiplied together to provide output signals at four times the frequency of the input signals. Filtering is provided to remove DC components, such as due to drift. In the illustrated metrological apparatus, the zero crossing points of the output signals are detected to effect sampling, with high resolution, of a surface sensor output. Interpolation noise occurs at a high frequency and is removed by low pass filtering of the sample signal from the surface sensor.
