Abstract: A television signal kind discriminating apparatus discriminates an input television signal in a short time between a MUSE signal having a three-value type horizontal synchronizing signal and a popular television signal such as an NTSC signal having a horizontal synchronizing signal consisting only of signals of a single polarity. An input television signal is converted into a binary signal by a level comparator using a level between first and second polarity signal portions of the horizontal synchronizing signal of the MUSE signal, and the binary signal is delayed by a predetermined time by a delay circuit. An exclusive OR signal between the binary signal not delayed and the binary signal delayed is outputted from a gate, and a temporal position of a mid point of the horizontal synchronizing signal of the input television signal is detected by a detector.

Abstract: A video signal processing circuit used for a non-interlace television comprises an interfield interpolation circuit for carrying out interfield interpolation by using a video signal before one field of an input video signal to output interpolated line video signals corresponding to respective interline positions in one field. An intrafield interpolation circuit carries out intrafield interpolation by using video signals of a plurality of lines of the input video signal to output interpolated line video signals corresponding to respective interline positions in one field. A motion detector detects motion of the input video signal, and a weighting adder implements weighting to an output signal from the interfield interpolation circuit and an output signal from the intrafield interpolation circuit in accordance with a signal from the motion detector to add the weighted output signals.

Abstract: A television receiver for extended definition television carries out scanning line interpolation in a way that eliminates picture shift on the screen and ensures normal display when supplied with a non-standard video signal having a scanning line count of other than 262.5 lines per field. The television receiver includes a scanning line interpolation circuit, a normal video signal detection circuit and a interpolation controller. The scanning line interpolation circuit effects scanning line interpolation using either data in the current field or out-of-field data as per the result of motion detection in the picture. The normal video signal detection circuit distinguishes the normal video signal from other signals by detecting the number of scanning lines involved. The interpolation controller causes the scanning line interpolation circuit to effect scanning line interpolation using only the inside-field data if the supplied signal is a non-standard signal.

Abstract: Interpolated scan lines are produced in response to received video signals which are comprised of conventional interlaced scan lines constituting successive fields. A delay circuit, preferably formed of field memory devices, such as three cascaded field memories, functions to delay the received video signals to provide a first scanned line signal in a given field, the next succeeding scan line signal in that field, an interlaced scan line signal in the next succeeding field and an interlaced scan line signal in the next preceding field. A first combining circuit combines the signal values of the next succeeding field interlaced scan line signal and the next preceding field interlaced scan line signal to form a first combined scan line signal. A second combining circuit combines the signal values of the first scan line signal in the given field and the next succeeding scan line signal in that field to form a second combined scan line signal.

Abstract: An artificial skin or bandage is formed from an elastomeric layer which is surfaced by a fibrous wound contacting layer which is first formed into a fabric and subsequently degraded by heat hydrolysis or other degradative treatment into a form which could no longer be formed into a fabric but which forms an ideal bioabsorbable wound contact surface in which damage to the newly formed, fragile epidermus is minimized.

Abstract: A digital scan converter having an oscillator providing a clock signal used to scan-convert an input video signal to thereby produce a scan-converted output video signal, an automatic frequency control for controlling the oscillator in synchronism with a synchronizing signal separated from the input video signal and a counter for frequency-dividing the clock signal from the oscillator to thereby form a control signal used for controlling blanking of the input video signal. The counter also provides an address signal for a memory in which the video signal is temporarily stored during the scan converting operation. Since a composite blanking pulse for the input video signal is formed in synchronism with the address signal for the memory, it is possible to prevent appearance of a jitter of the composite blanking pulse on a display screen.

Abstract: The present invention relates to a working method of breaking up a ship, particularly a large ship, and is characterized by cutting the hull to shorten the length thereof as it is floating on the sea, and more particularly characterized by, on the cutting of the hull, inserting a buoyancy body under the stem portion or the stern portion to trim the hull and floating up said portion and locating there a marine workshop, drawing the hull into the marine workshop while performing breaking up the hull. According to the present invention, it is possible to break up a hull without special harbor facilities and even at locations such as the lee of island and other position where there is no harbor facilities. Also, since the hull is drawn in the marine workshop and broken up to shorten the length of the hull, the working is greatly simplified compared with a prior method wherein the hull is broken up to shorten the height thereof, and as a result the working period can be shortened.
