Abstract: A method is described by which the electromechanical properties of heads or head wheels of magnetic recording apparatuses can be improved by avoiding the oscillating of limited duration at the point of tape/head contact, causing picture disturbances, which is known as the "rubbing noise effect". This improvement is achieved by oscillation loading of the head induced externally, for example by means of ultrasound. This method can be used to repair apparatuses already in operation on which the rubbing noise effect occurs.

Abstract: This invention relates to solventless, curable polyorganosiloxane compositions, and in particular, to solventless, curable polyorganosiloxane compositions that can be used to prepare release coatings. Solventless silicone compositions generally provide release surfaces that exhibit a sticky or rubbery feel, which is disliked by users of certain types of transfer tapes. Users of large transfer tapes, e.g., tapes consisting of a layer of a pressure-sensitive adhesive borne on a removable silicone release liner, prefer to place the tape on the desired substrate, then press the tape down firmly with their hand or forearm, remove the silicone release liner, and then press the second substrate in contact with the exposed surface of the tape. The users desire that the release liner exhibit a slippery feel so that the friction between the liner and their hand or forearm not bring about chafing of the skin. This invention provides curable, solventless, liquid polyorganosiloxane compositions for providing release coatings that exhibit a slippery feel. The composition comprises (a) a first polydiorganosiloxane terminated by silyl groups having one reactive group; (b) a second polydiorganosiloxane terminated by silyl groups having one reactive group, the reactive group of (a) being the same or different from the reactive group of (b), said reactive groups of (a) and (b) being reactive with one another to form a covalent bond; (c) a polydiorganosiloxane having three or more reactive groups that are reactive with either the reactive group of (a) or the reactive group of (b) or both to form a covalent bond; and (d) a catalyst for effecting the reaction of the reactive groups of (a), (b), and (c) to form covalent bonds. When coated on a substrate and cured, the composition provides release liners for pressure-sensitive adhesive tapes and pressure-sensitive adhesive transfer tapes.

Abstract: Upon feeding a belt-like member (22) cut into a fixed length on a conveyor (5) by means of a cutter (40) to a drum (1) by means of the conveyor (5) and wrapping it around the circumferential surface of the drum (1), the cut length of the belt-like member (22) is set to be somewhat shorter than the circumferential length of the drum (1). At the time of wrapping, the belt-like member (22) is stretched by a predetermined amount to make its leading and trailing ends coincide with each other after the completion of wrapping. The belt-like member (22) is cut by making the cutter (40) travel along a predetermined straight reference line of travel. The configuration of the lines of cut at the leading end and at the trailing end are measured, and also a straight line approximating the line of cut, the inclination angle of the approximating straight line with respect to the predetermined straight reference line of travel, and the amount of deviation from the predetermined straight reference line of travel at respective points on the line of cut are obtained. The direction of the cut trailing end and/or the cut leading end are corrected on the basis of the obtained inclination angle (ϑ) so as to coincide with each other, the belt-like member (22) is held and set on the conveyor (5), and the amount of stretching of the belt-like member (22) upon wrapping is corrected on the basis of the obtained amounts of deviation.

Abstract: A phase-shifted diffraction grating for devices such as semiconductor lasers is produced by forming a first diffraction grating pattern of a first material having a reference pitch on a substrate. The substrate is then coated with a second material on both the first material and an exposed portion of the substrate in a region where a second diffraction grating having a pitch which is the reverse of the reference pitch of the first diffraction grating pattern is to be formed. The first material is removed by lift off to obtain the second diffraction grating pattern on the second diffraction grating region. The substrate is etched using the first diffraction grating as an etching mask to form the first diffraction grating and then the substrate is etched with the second diffraction grating pattern as an etching mask to obtain a second diffraction grating continuous with the first diffraction grating. The first diffraction grating pattern may have a rectangular or square shape to stably and accurately remove the first material by lift-off and the boundary between the first and second diffraction gratings can be stably and accurately defined by self-alignment.

Abstract: Pulse Width Modulation (PWM) techniques, often used to reduce the power dissipation in polyphase motors, chop the current in the coils of the motor at their peak current levels, to achieve maximum torque, to allow rapid accelerations, and to reduce the power dissipated in the chip to a level proportional to the duty cycle. During the time the current is switched off, the current which has been established in the coils of the motor is allowed to be dissipated. Accordingly, when the switching transistors of the active coils are turned off during PWM mode chopping, a non-rectifying ground return path is provided for flyback energy in the active driving coil. This non-rectifying ground return path is provided by switching transistors in parallel with flyback diodes, operated in a form of synchronous rectification. This gives an alternate current path for the coil current to reduce the voltage drop across the diodes, and thereby reduce the power dissipation and heat in the chip.

Abstract: Gray pixel values, where the value of the pixel has one of a relatively large number of input levels, are directed through an error diffusion quantization process, for the conversion to one of a relatively small number of values. Each pixel of the gray level data (18) is modified (10) by a correspondingly weighted error correction term (20,22,24,28) or terms from previously processed pixels, generating a modified pixel value (12). This modified pixel value is compared (14) to a threshold value, the threshold value determined adaptively (15), based on 1) a dither pattern, having a dynamic range greater than 1, and 2) the value of the pixel to be thresholded, and optionally on its predetermined neighborhood, multiplied by a value representing an edge enhancement factor. The difference value between the modified pixel value (12) and the output pixel value (16) is distributed in accordance with a weighted distribution scheme to a set of neighboring unprocessed pixels, increasing or decreasing the gray values of such pixels.
