Abstract: Methods and compositions comprising an anti-ostepontin agent and/or a PDGF receptor blocker or antagonist, alone or in combination with one or more anti-connexin agents, for example, one or more anti-connexin polynucleotides and/or one or more anti-connexin peptides or peptidomimetics, are provided for the promotion and/or improvement of wound healing and/or tissue repair, and for anti-scarring, anti-inflammatory, anti-fibrosis and anti-adhesion indications.

Abstract: Many boards 7 to be processed are disposed within a metal chamber 1 in an isolated state, and many ground electrode plates 9 are disposed near by both surfaces of the boards 7 so as to be at the same potential as the chamber 1. While a microwave generated by a magnetron 3 from an upper portion of the chamber 1 is applied in the chamber 1, both surfaces of the boards 7 are processed at a time with plasma by using glow discharges produced between the boards 7 and plates 9 due to a difference in high-frequency potential between the boards 7 and plates 9 under presence of reaction gas.

Abstract: Bit "0" and bit "1" constituting a digital signal are replaced with extended length binary coded signals. For example, bit "0" of the digital signal is replaced with "011", and bit "1" with "110". The replaced signals are recorded in a non-rewritable recording medium. A bit "0" of the recorded signal does not change a status of the recording medium whereas a bit "1" of the recorded signal changes the status of the recording medium. Unauthorized change of the data recorded in the recording medium can be recognized if the data read on a three-bit basis indicates "111". A header may be additionally recorded in the recording medium to store status of the data recorded therein.

Abstract: The reliability of a tamper resistant module for safeguarding stored information, e.g. in an electronic computer system, is improved to deny access to the system by an unauthorized person or at least to a specific portion of the system. For this purpose, the module has for example a pair of substrates which are bonded together to confine confidential data inside the module. On the outer surfaces of the substrates, a plurality of logical elements, such as transistors, form detecting memory devices. The plurality of these detecting memory devices are operative under a normal condition, but at least one of these detecting memory devices is rendered inoperative when a tampering is applied to the outer surface of the substrate. In a tamper free normal situation all memory devices work properly. The inoperability of any of the detecting memory devices is detected when tampering occurs. When the tamper is detected, the confidential data confined within the module are erased.

Abstract: A video signal processing system improves the image quality displayed in a CRT or printed by a video printer. In order to produce natural and fine video signals, pixel data corresponding to an intermediate position between two neighboring pixels, are produced from pixel data of the neighboring two pixels. The pixel data corresponding to the intermediate position is produced by a convolution operation with respect to the pixel data of the two neighboring pixels and a quantized value of an impulse response signal.

Abstract: A signal modification circuit receives an input signal and produces an output having a modified characteristic. When the signal modification circuit is embodied in an audio circuit receiving an analog audio signal having a first variant level at its input, the audio circuit produces an output signal having a second variant level in which a frequency characteristic in a high frequency range is modified so that the second variant level decreases in accordance with a function of l/fm (f being frequency and m being an integer determined depending upon the nature of the audio signal) relative to the first variant level while being trapped in selected discrete frequencies. For this purpose a combination of a low-pass filter and a plurality of trap filters connected in series with one another, or a combination of a low-pass filter and a plurality of band-pass filters connected in parallel to one another.

Abstract: A system for storing data on the history of use of programs consisting of a data processing apparatus and a program storage unit, such as a magnetic tape, which stores program-specific data. The data processing apparatus includes a user-specific credit data storage portion, a use decision portion, and a program use history storage portion which can store use history data derived from the program-specific data from the program storage unit or the user-specific credit data from the user-specific credit data storage portion. The program use history is accessible to proprietors of the programs so that charges can be based on actual use of the programs.

Abstract: A data generator generates digital data at a sampling time interval .sub..DELTA. T (sampling frequency f.sub.s =1/.DELTA.T), and the three latest items of digital data V.sub.-1, V.sub.0, V.sub.+1 are repeatedly latched successively in three latch circuits every 3.multidot..sub..DELTA. T. A pulse response signal generator outputs unit pulse response signals of period 3.multidot..sub..DELTA. T at the time interval .multidot..sub..DELTA. T, and three multiplying-type DA converters multiply these three unit pulse response signals .phi..sub.0 (t+.sub..DELTA. T), .phi..sub.0 (t), .phi..sub.0 (t-.sub..DELTA. T) by the digital data V.sub.-1, V.sub.0, V.sub.+1, respectively, at a speed of a.multidot.f.sub.s (a times in time .sub..DELTA. T). The outputs of these multiplying-type DA converters are combined into an analog signal S.sub.A, which is delivered as an output.
