Abstract: The object of the present invention is to provide an ink jet recording sheet which can give an image having an appearance looking like a picture, especially, an oil painting with maintaining sufficient print density. According to the present invention, there is provided an ink jet recording sheet comprising a support and an ink receiving layer provided on one side of the support, where the support is a fabric and the surface of the ink receiving layer has an arithmetical mean roughness of not more than 30 ?m measured in accordance with JIS B0601. The present invention further provides an ink jet recording sheet mentioned above, wherein the ink receiving layer is coated on a pigment layer coated on at least one side of the fabric or on at least one side of the fabric impregnated with a pigment component. The ink receiving layer preferably contains a gas phase method silica.

Abstract: A digital demodulator compensates for frequency offset between modulated and unmodulated carrier signals by detecting the frequency offset during a preamble with a known modulation pattern. Samples obtained during the preamble are stored in a memory during clock recovery, and read from the memory after the recovered clock signal has become stable. Phase offset is detected from a histogram of the phase differences between the two carrier signals, calculated modulo a certain phase angle, and compensation for phase offset is applied. The maximum histogram value is found by comparisons made according to a single-elimination tournament plan. In a diversity receiver, the maximum histogram value is used to select the output data.

Abstract: An instantaneous phase detecting circuit for detecting the phase of a digital phase modulation wave signal which includes first and second logic circuits, first and second phase detecting circuits, and a third logic circuit. The first and second logic circuits receive the modulation wave signal, the first logic circuit receives a first carrier signal, and the second logic circuit receives a second carrier signal, the phase of the second carrier signal being delayed by a fixed period with respect to the phase of the first carrier signal. The first and second logic circuits generate first and second arithmetic outputs which are received by the first and second phase detecting circuits which detect the phases of the first and second arithmetic outputs to generate first and second detection output signals respectively.

Abstract: A coherent phase-shift keying (PSK) detector in a receiver generates an unmodulated carrier signal, without attempting to synchronize the unmodulated carrier signal in frequency or phase to the carrier employed at the PSK transmitter. The instantaneous phase of the received PSK signal is detected with reference to the unmodulated carrier signal to create an instantaneous phase signal. Phase rotation due to frequency offset between the two carrier signals is detected and removed from the instantaneous phase signal, then a remaining phase offset is detected and removed. Data are recovered from the resulting instantaneous phase signal.

Abstract: A clock recovery signal generating circuit for generating a clock recovery signal includes a plurality of detection axis cross detectors varied in magnitude of detection axis admitting a phase difference signal, for detecting the time at which the phase difference signal crosses the detection axis of a prescribed magnitude. A locus sorter discriminates and sorts the locus of a change in the phase difference signal based on the data of timing obtained by the detection axis cross detectors and generates a timing adjusting signal in conformity with the result of the sorting. Timing control generates a clock recovery signal by correcting the data of timing obtained by one of the plurality of detection axis cross detectors designated by the timing adjusting signal with the time designated by the timing adjusting signal.

Abstract: A plastic-model kit having a plurality of components containing at least one die sheet for molding having cavities therein and at least one thermoplastic resin having a low softening temperature, the die sheet and the thermoplastic resin being packed together in a unitary package. The thermoplastic resin can be softened, by dipping in hot water, for example, at about 60.degree. C. to 80.degree. C., and the softened resin can be cast by hand or by a simple tool into the cavities on or through the molding die sheet and then cooled at ordinary temperature (that is, 20.degree. C. to 30.degree. C.) to form various shaped and sized pieces for the plastic-model kit. Ornaments or decorations having a three-dimensional or roughly three-dimensional visuality such as for dolls, human models, animal models, building models, ship models, car models, airplane models, and the like can be assembled from the plastic-model kit.
