Patent EP-0329395-A2 (EP)
Inventor: MORISAKI KAZUHIKO
IPC: G11B5/008
Filed: 1989-02-15
Abstract: A magnetic recording and playback apparatus comprises a rotary drum having an inclined center of rotation to the running direction of a magnetic recording tape, a group of first and second channel recording heads and a group of first and second channel playback heads mounted on an outer periphery of the rotary drum at an angular interval of substantially 90 degrees, of which recording and playback heads alternate their positions along the outer periphery. The axial distance between the recording head group and the playback head group track pitch Tp of consequently formed tracks. The first and second channel recording heads alternately form first and second tracks in sequence on the magnetic recording tape, and after the second track is formed by the second recording head, a recorded signal on the first track is outputted by being traced with the first channel playback head.

Abstract: A process is provided for fabricating con­tacts (46s, 40g, 46d) in a completely self-­aligned, planarized configuration for EPROM elements (66). The process of the invention permits higher pack­ing densities, and allows feature distances to approach 0.5 µm and lower. The EPROM element comprises source (18) and drain (20) regions separated by a gate region (22) and is characterized by the gate region comprising two separate gates, a floating gate (40g) and a control gate (58), capacitively coupled together. The floating gate is formed on a gate oxide (38) over the substrate (16) and the gates are separated from each other and from the source and drain contacts by a dielectric (56). The EPROM element has two threshold voltages, one related to the operation of a "normal" MOS transis­tor and the other related to a "programmed" threshold, following programming of the transistor. Sensing the threshold voltage of the device permits a determination to be made whether the device is programmed. UV radia­tion erases the programming and restores the threshold voltage of the device to its pre-programmed level.

Abstract: A recursive noise reduction filter for video components reduces the noise bandwidth of a signal without degrading the signal spectrum. Demodulated chrominance or peak detected chrominance from a video signal output by a video system in response to a video test signal is input to the recursive noise reduction filter (24) which acts as a comb filter to suppress noise significantly at frequencies other than harmonics of the horizontal line rate. The signal is scaled by a first attenuator (30) having a scaling factor of (1-a), where (a) is less than one, and input to a summing circuit (32). Also input to the summing circuit is a delayed signal from a prior horizontal line scaled by the scaling factor (a). The output of the summing circuit is a filtered output signal. The signal is sampled only during horizontal lines that have the video test signal and is stored for subsequent accumulation with other horizontal lines also having the video test signal. The filter serves to add the vertically correlated part of the signal corresponding to the video test signal while averaging out the noise, thus improving the overall signal to noise ratio without degrading the signal spectrum and, hence, enhancing differential gain and phase measurements.

Abstract: Redundant pulses generated by independently operable pulse sources in an electricity meter are accumulated as pulse counts in a pair of channels of a multi-channel recorder. The pulse counts are compared to verify the accuracy of the pulses counted by each channel. If the difference between the values of the pulse counts exceeds a predetermined threshold value, a trouble indicator is turned on and a telephone call is initiated by the recorder to notify a data center that a system malfunction has occurred which is disrupting the accumulation of pulses in one of the channels of the recorder. The pulse counts are stored in the recorder as substantially duplicate independent measures of energy usage by a load connected to the electricity meter, to be thereafter retrieved from the recorder to obtain energy survey and billing data. The recorder also maintains a system status error log which records the time and date of each malfunction and the identification of the channel pair where the malfunction occurred. In one embodiment, the operation of the recorder is controlled by a programmable microprocessor. Combinations of independent power sources for powering the recorder and the pulse sources are employed to enhance system reliability by making each of the pulse sources and the recorder substantially independently operable.

Abstract: A semiconductor laser array with features pro­viding good beam quality at higher powers, first by employing a laterally unguided diffraction region (14) in which light from a set of waveguides is re-imaged in accordance with the Talbot effect and two arrays of waveguides (10,12) may be used to provide a spatial filtering effect to select a desired array mode. This provides a laser array with increased power per unit solid angle, and with additional advantages of ability to scale the device up to larger arrays, ability to control the electrical excitation of the device for better optimiza­tion, and improved modal discrimination. A second as­pect of the invention is the use of a resonance condi­tion in an antiguide array, to produce a uniform near­field intensity pattern and improved coupling and de­vice coherence. This resonance structure may be com­bined with the Talbot-effect structure to suppress the out-of-phase mode, or the out-of-phase mode may be suppressed by other means, such as by introducing interelement radiation losses or absorption losses in the antiguide array.

Abstract: Disclosed herein are high-temperature oxide super­conductors of RBa₂Cu₄O₈ type, with Ba partly repaced by Sr or Ca, or with R and Ba partly replaced by Ca and Sr, respectively, as represented by the chemical composition formula of R(Ba 1-y Sr y )₂Cu₄O₈ or R(Ba 1-z Ca z )₂Cu₄O₈ or (R 1-x Ca x )(Ba 1-y Sr y )₂Cu₄O₈. They exhibit superconductiv­ity at high temperatures. Especially, the last one exhib­its superconductivity at a higher temperature than the former two. All of them can be made with a less amount of Ba as a deleterious substance, and the first two have improved sinterability. The best results are obtained when they are produced by the process involving the hot hydrostatic pressure treatment of the mixture of raw mate­rials at 850-1100°C in an atmosphere composed of an inert gas and oxygen. The process permits a wider selection of Ba raw materials.
