Abstract: The present invention discloses texturing of the slider air bearing surfaces (18a,18b) of the magnetic heads in disk drives to reduce striction that retards take-off and displaces critical lubricant in a magnetic head system. One embodiment utilizes nonuniform etching of chemically identical components of a ferrite slider material due solely to random crystal orientation relative to the exposed surface. Another embodiment utilizes a photoresist of a type used in making printed circuit boards, to form a pattern. Subsequently, the surface may be etched to form the anti-striction properties. A variety of controlled and reproducible patterns as well as a controlled depth of pattern may be utilized.

Abstract: This invention is a semiconductor vertical cavity surface emitting laser comprising a lasing cavity with an active layer (14), a bottom (rear) mirror (12) and a top (front) mirror (17), and a front and rear electrodes (17,18) for applying excitation current in direction substantially parallel to the direction of optical propagation. In accordance with this invention the front mirror comprises a thin, semitransparent metal layer (17) which also acts as the front electrode. The metal layer is upon a highly doped layer (16) forming a non-alloyed ohmic contact. The metal is selected from Ag and Al and is deposited in thickness ranging from 5 to 55 nm. The VCSEL is a semiconductor device wherein the semiconductor material is a III-V or II-VI compound semiconductor. For a VCSEL with GaAs active layer, the light output from the front metal mirror/electrode side yields a high external differential quantum efficiency as high as 54 percent. This is the highest quantum efficiency obtained in VCSEL structures. Quantum efficiences on the order of 10 to 30 percent are typical for prior art VCSEL structures. The VCSEL is suitable for fabrication utilizing planar technology.

Abstract: In a visual display system for a simulator, a pattern processor (20) for applying surface detail modulation to the uniform intensity values output from the simulator memory database for polygon surfaces has each tile of modulation values stored in a respective tile store (46) of eight lookup and weight units (30-37). Four different modulation values are looked up from the four units (30 to 33 or 34 to 37) of two groups and are weighted, and then summed by a respective summing circuit (28 or 29) before blending (22) and application to the modulator (11). A microinterpolation limit (39) associated with the polygon surface allows the weighting factors to bias the summing circuit outputs towards one of the respective four looked up values, thereby enhancing step-like intensity changes within the polygon.

Abstract: A musical tone generating apparatus utilizing a data compression method is disclosed. A musical tone is sampled and is converted into waveform data (S(n)). These waveform data (S(n)) are compressed into compressed data (C(n)) by a linear predictive coding method and further by a differential quantization method. The number of bits of each of the compressed data (C(n)) is thus significantly smaller than that of the waveform data (S(n)). Thereafter, a memory (2) stores the thus compressed data corresponding to an attack portion of the tone and a selected part of a sustain portion of the tone. Hence, it is possible to remarkably reduce the memory storage. When generating a musical tone, the memory (2) reads out the compressed data (C(n)) of the attack portion and thereafter repeatedly reads out the compressed data of the selected part. The read-out compressed data are sequentially decoded into the original digital data. Thus, the whole waveform of the musical tone is reproduced.

Abstract: A process for removing CO₂ from a combustion gas which comprises bringing a combustion gas containing oxygen and CO₂ and a CO₂ absorbent solution into contact at the atmospheric pressure, thereby allowing the CO₂ absorbent solution to absorb CO₂ from the combustion gas, and, in the ensuing step, heating the absorbent solution that has absorbed CO₂ to liberate CO₂ and regenerate the CO₂ absorbent solution, and circulating the regenerated solution for reuse. An aqueous hindered amine solution is used as the CO₂ absorbent solution, and carbon steel is used in building the members of the equipment that contact the aqueous hindered amine solution. The absorbent solution may contain cupric carbonate. The invention is advantageously carried into practice on an industrial scale because of low equipment cost owing to little corrosion and a saving of the energy required for the regeneration of the absorbent solution.

Abstract: To improve the sharpness of (video) pictures to be displayed on a display screen of a display device, it is known to use scan velocity modulation. The drawback of scan velocity modulation is that an improvement of the (impression of) sharpness is obtained in given types of video signal/pictures only. By starting from the properties of the display tube when improving the (impression of) sharpness of the displayed picture, a much better improvement can be obtained. Information about the relevant display tube is applied to a correction circuit which also receives a video signal-dependent signal. With reference to these input signals the correction circuit determines whether and how the video signal is to be corrected so as to obtain an ideal picture on the display screen. Reducing the contrast is a first step of restoring the resolution. Modulating the read clock of the video signal is a second step. Using scan velocity modulation is the last step. The correction circuit determines/computes one clock signal which is applied to a contrast control circuit, a clock modulator and a scan velocity modulator, respectively.

Abstract: An image transfer method uses an image-forming material comprising a substrate 17, a photosensitive layer 18 formed on the substrate and a protective film 19 exfoliatively attached to the photosensitive layer. The method comprises mounting a sheet of the image-forming material on a roller 8, peeling off the protective film 19, and introducing the image-forming material into a nip formed between the roller 8 and another surface 1 so that the photosensitive layer 18 of the image-forming material and an image receptor come into contact with each other selectively to transfer part of the photosensitive layer to the image receptor to produce an image thereon. The protective film 19 has previously been attached to the photosensitive layer 18 with the substrate 17 tensioned at substantially right angles to the axis of the roller 8. Accordingly, when the protective film 19 is peeled off, the substrate 17 stretches tightly around the roller 8 to eliminate undesirable crinkling, thereby improving image transfer quality.
