Abstract: A recovery routine enables data to be read from a sector of an optical data disk in the presence of damaged or missing syncs. If a sync is found, a "sync found" signal is generated to designate a normal read operation, and blocks of data read from the sector are aligned to resyncs distributed in the data stream. If a sync is not found, a pseudo sync is generated to designate a data recovery operation, and blocks of data are aligned to resyncs found in the data stream during a single pass or during separate passes through the sector at the user's option. The syncs and resyncs are searched using windows of programmably variable size for the read and recovery operations.

Abstract: A dc-dc converter employs both half-bridge topology and current-mode switching control. The controller operates by sensing the current (1 s ) that flows through the transformer (T) that is interposed between the node (13) of two series switches (S₁₁S z ) and the node (14) between the two split capacitors (C₁₁C₂). The controller develops gating signals to close and open the switches based on the rise of current to a predetermined command level (V ref ). A gate signal for the second switch (S₂) which is developed between actuations of the first switch (S₁) , has its pulse width made equal to the period that the first switch was closed. This maintains a balanced voltage-time product, so that the series or split capacitors (C₁₁C₂) remain in balance. The controller (21) can include a sample gating circuit with a comparator (27) that receives the current sample signal and the command level. The track side signal which develops the gating pulse for the other switch can be developed with analog circuitry, i.e. by charging a capacitor (35), or else digitally, i.e. in clock pulse counters (51,53).

Abstract: An identification system is provided having a stationary member and a portable passive member adapted to derive its operating power from the stationary member. A first coupling device such as a coil antenna is provided on the stationary member for transmitting a signal of a predetermined frequency via a magnetic field. A second coupling device provided on the portable member receives that signal and a power device derives operating power for the portable passive member from that signal. A third coupling device on the portable passive member transmits coded information stored on circuitry in the portable member via magnetic field. This third coupling device is offset from the second coupling device so that the net flux generated in the second coupling device from the third coupling device is approximately zero. A fourth coupling device provided on the stationary member receives the coded information transmitted by the third coupling device. The fourth coupling device is offset from the first coupling device so that the net flux generated in the fourth coupling device from the first coupling device is approximately zero. By utilizing the offset of the receive and transmit coupling devices on each member, simultaneous magnetic transmissions can be sent by both the stationary member and the portable member.

Abstract: The interface circuit of the present invention adjusts the signal voltage across a leaking transistor (220) such that the leakage is reduced while also shunting out the adjustment means (225) when the adjustment means (225) impedes the operation of the interface circuit. One embodiment of the present invention is a level translator comprised of a level shifting stage coupled to a buffer stage. The level shifting stage has its power source coupled to a current shunting device (250). The current shunting device (250) is connected in parallel across the first P-channel device (225) of the level shifting stage. The first P-channel device (225) of the level shifting stage is connected in series with a second P-channel device (220) having its drain connected to a drain of a first N-channel device (215) wherein the first N-channel device (215) has its source connected to a drain of a second N-channel device (210). The current shunting device is formed from a single P-channel device (250). The connection (217) between the drains of the second P-channel (220) and the first N-channel device (215) of the level shifting stage is an input to an inverter (255) , which in turn, has its output (263) connected to the input of the current shunting device (250). When the input to the level shift stage is at the high voltage logic signal level, the input to the inverter is low and the output of the inverter (255) is at a high voltage logic signal level. The high voltage logic signal level then turns off the P-channel device (250) of the current shunting device. The first P-channel device (225) of the level shifting stage has its gate connected to its drain which reduces leakage current in the level shifting stage and reduces the power consumed by the interface circuit when the current shunting device (250) is turned off. When the input to the level shift stage is at the low voltage logic signal level, the input to the inverter (255) is high and the output of the inverter (255) is at a low voltage logic signal level. The low voltage logic signal level allows the current shunting device (250) to directly supply current to the second P-channel device (220) of the level shifting stage and shunts out the first P-channel device (225). Therefore, the shunted out device does not interfere with the performance of the level shift stage of the interface circuit.

Abstract: When liquid/solid mixtures are separated in centrifuges, in particular in worm centrifuges, with the objective of recovering the liquid phase as a valuable material, discharging the liquid via skimmers frequently leads to eddying of the liquid with the gas (normally air) present in the centrifuge, which can lead to an undesired high degree of foam formation and to an undesired reaction of the gas with the liquid. According to the invention, in order to prevent this eddying it is proposed to construct the skimmer (14) from at least two individual discs (15, 16) which can be rotated with respect to one another and form between them at least one skimming duct (20) whose cross-sectional area can be adjusted by rotating the individual disks (15, 16) and can thus be adapted to the rate of discharge. <IMAGE>

Abstract: In order to form a single-crystalline thin film on a polycrystalline substrate using plasma CVD, a downwardly directed mainly neutral Ne atom current is formed by an ECR ion generator (2). A reaction gas such as silane gas which is supplied from a reaction gas inlet pipe (13) is sprayed onto an SiO 2  substrate (11) by an action of the Ne atom current, so that an amorphous Si thin film is grown on the substrate (11) by a plasma CVD reaction. At the same time, a part of the Ne atom current having high directivity is directly incident upon the substrate (11), while another part thereof is incident upon the substrate (11) after its course is bent by a reflector (12). The reflector (12) is so set that all directions of the parts of the Ne atom current which are incident upon the substrate (11) are perpendicular to densest planes of single-crystalline Si. Therefore, the as-grown amorphous Si is sequentially converted to a single-crystalline Si thin film having crystal axes which are so regulated that the densest planes are oriented perpendicularly to the respective directions of incidence, by an action of the law of Bravais. Thus, a single-crystalline thin film is formed on a polycrystalline substrate.

Abstract: A distributed feedback semiconductor laser selectively performs one of two oscillations in different polarization modes having different polarization planes. The laser includes a subtrate, a light waveguide formed on the substrate, which at least partially includes an active layer, a a diffraction grating formed around the waveguide, and an injecting unit for injecting a modulation current into a portion of the waveguide. The waveguide and the grating are constructed such that oscillation wavelengths of the polarization modes are different from each other and minimum values of threshold gain in the polarization modes near the Bragg wavelength are approximately equal to each other. The semiconductor laser can be driven by a minute modulation current and prevents degradation of response characteristics due to dynamic wavelength fluctuation in a high-frequency range when used in optical communication systems in which the switching of polarization mode is performed.
