Inventor: SEMBA TETSUO
IPC: G11B7/095
Filed: 1994-04-11
Abstract: Errors (offset and amplitude error) of the focus error signal and the tracking error signal are detected for at least three track jumps by making use of a track jump performed once per rotation of a disk in the track following mode (for a spiral disk). An offset value of the focus error signal is calculated based on the amplitude of a tracking error signal generated for at least two of the track jumps, performed by adding a positive or negative offset to the original target value of the focus error signal. The values of offset and amplitude error of the tracking error signal are calculated based on a maximum value and a minimum value of a tracking error signal generated for at least one track jump performed without modifying the original target value of the focus error signal. Thus calibration of the tracking error signal and the focus error signal can be performed repeatedly even when an optical disk drive is in the normal operation mode.

Abstract: The attitude of a spinning spacecraft (20) whose spin axis is substantially in the plane of the orbit is controlled without the use of reaction control thrusters. A two-axis gimbal (24) on which a momentum wheel (26) is mounted is secured to a central body (21). Two actuators (40, 42) are used to selectively pivot the gimballed momentum wheel (26) about each gimbal axis (x, y) in order to apply a control moment to change the attitude state of the spacecraft (20).

Abstract: A scroll compressor oil pumping system has a concentric axial bore located in the driveshaft of the compressor which serves as the primary oil pump. The driveshaft is journaled in a lower bearing housing and is located within the oil sump of the compressor. An inlet housing is attached to the lower bearing housing and creates a stepped flow path for the oil between the sump and the oil pump. The inlet housing may also be equipped with a plurality of air foil shaped vanes to impede the formation of a bottom vortex. The stepped flow path causes an annular vortex to form which operates to separate the contaminants from the lubricating oil. In order to assist in the formation of the annular vortex, the driveshaft can include an impeller. The contaminants are channelled into a holding chamber formed by the lower bearing housing and the inlet housing. A plurality of funnel shaped orifices guide the contaminants into the chamber and operate to resist blow out of the debris during liquid flashing conditions. A magnet can be included within the holding chamber to attract the metallic contaminants if desired.

Abstract: A workpiece is formed comprising a silicon substrate (12,14,16) covered by four successive layers of silicon dioxide, undoped polysilicon, undoped WSi₂ and a top layer of silicon dioxide on silicon nitride. The four layers are patterned to provide gate electrode structures (30,40) each comprising the four layers. The workpiece is covered with a masking layer (42) and the top layer (28a) of each structure is exposed through the masking layer. The top layers are then removed and ions of one conductivity type are implanted into the WSi₂ layers of one group of gate electrode structures while another group of structures is masked, and ions of the other conductivity type are implanted into the WSi₂ layers of the second group while the first group is masked. Thereafter, doped regions are formed in the substrate adjacent to the gate electrode structures.

Abstract: Methods are disclosed for predicting RF propagation within a structure such as a building, characterized by the following steps. A reference transmitter location (210) and a plurality of reference receiver locations (212) are selected. For each reference receiver location, RF propagation pathways are determined with respect to the reference transmitter location. The RF propagation pathways include a direct path (217) joining the reference transmitter location to a given reference receiver location across a straight-line path, as well as one or more reflection paths (219) joining the reference transmitter location to a given reference receiver location via reflections from one or more reflective surfaces (216). One or more propagation pathways may pass through an RF obstacle, such as, for example, a lossy dielectric material (214). Each reflective surface and RF obstacle is associated with a reflection coefficient and a transmission coefficient. These coefficients are computed for each object and surface from a multilayer dielectric model, maintaining angle and polarization dependencies. For each propagation pathway, a propagation component consisting of the propagation loss relative to free-space propagation is calculated as the product of the magnitude squared of the reflection and transmission coefficients. The local mean of received RF power at each of the reference receiver locations is calculated as the scalar sum of the powers of all the propagation pathway components reaching the specified location.

Abstract: A method for using a remotely positioned MRI device to image a material with an inhomogeneous magnetic field requires maintaining an encoded coherence of all components of nuclear magnetization in the material during the imaging process. To do this, the encoding of nuclei is accomplished first, and then the nuclei are repetitively refocussed to obtain recordable net magnetic moments. This is repeated as part of a two-step recording sequence wherein first one component of the refocused nuclear magnetization is recorded and then the other component of the refocussed nuclear magnetization is recorded. Importantly, for each step in the recording sequence the encoding and the repetitive refocussing of the nuclei are accomplish separately. Specifically the method includes the steps of: tilting the nuclei with a 90° pulse; encoding the nuclei with a gradient; pulsing the encoded nuclei with a train of 180° pulses having a first phase angle to generate a pattern of magnetic moments; and recording the pattern. All of this is then repeated using 180° pulses with a different phase angle. The method also contemplates combining a plurality of patterns to create an image of the material.

Abstract: In order to produce the cathode layer of a molten carbonate fuel cell in which the cathode layer is part of a sandwich structure also comprising a matrix layer and an anode layer, a porous cobalt or iron layer is filled with lithium carbonate, the cobalt or iron layer is oxidized at a temperature below the melting point of the lithium carbonate in an oxidizing atmosphere, so that a cobalt or iron oxide layer is produced, and after the temperature is increased above the lithium carbonate melting point, the cobalt or iron oxide reacts with the molten lithium carbonate, producing lithium cobaltide or lithium ferrite. The thus produced cathode layer allows high current densities with insignificant voltage losses and has an extremely low solubility in molten electrolytes.
