Insertion guides are mounted to slide blocks supported by a guide to be close to or away from each other. The slide blocks are meshed with nut parts of a ball screw threaded in both directions. When the ball screw is rotated via a driving pulley, a belt, and a driven pulley by a rotating/driving device set in an insertion head, the slide blocks and insertion guides mounted to the slide blocks are moved, so that an insertion pitch is changed. When the insertion head is rotated by a rotating/driving device via a driving pulley, a belt, and a driven pulley, an insertion direction is changed as well.

An apparatus is provided with a component feeding member for feeding electronic components having lead wires in a tape-bonded state, an insertion head for separating the electronic components fed from the feeding member from the tapes and inserting to holes of a board, and a fixing head facing the insertion head via the board for cutting and folding the lead wires of the inserted electronic component in the board thereby fixing the electronic component to the board. AC servo motors operating independently of each other are individually set in the insertion head and the fixing head, which are controlled by a device so as to be synchronous with each other.

An apparatus for the processing and segmenting of a cover-forming laminate web or sheeting structure which is adapted to interconnect a plurality of containers, such as the base members of blister packages each of which is designed to contain a hydrophilic contact lens in a sterile aqueous solution. More specifically disclosed is an apparatus for the imprinting, perforating, slitting and cutting the laminated web structure such that the severed laminate segments constitute printed covering label for an array of such containers, and whereby the laminated web or sheeting segment may be severed along weakening or perforation lines so as to provide a separable packaging arrangement for individual of the containers which are subsequently adhered thereto.

An I-axis phase pulse is allowed to be detected at the sampling point of a chrominance signal with a digitally-implemented circuit. A chrominance signal (sampling frequency f.sub.1) is subsampled by a frequency f.sub.2 (f.sub.1 /N) and subsampling pulses generated in N subsampling pulse generators 10 for N phases, the adjacent ones of the pulses being shifted by one clock (1/f.sub.1) with respect to one another. The subsampled chrominance signal is input to an I-axis determining circuit 17. The I-axis determining circuit operates to detect a maximum value M.sub.1 of a color burst signal (sampling frequency f.sub.1) and the data M.sub.2 after one clock and compare both of the values with each other. Based on the compared result, a selecting signal S.sub.4 is detected for selecting an I-axis phase pulse at the sampling point of the chrominance signal. A selecting circuit 18 selects, as an I-axis phase pulse S.sub.5, a proper one of the N sampling pulse for N phases based on the selecting signal and applies the I-axis phase pulse S.sub.5 to an (N+1)th subsampling circuit 19. The subsampling circuit 19 can provide an I-axis detected output S.sub.3 at the sampling point of the chrominance signal.

A noise reduction apparatus for use in a television receiver or VCR using the NTSC format, in which a video signal or a demodulated color difference signal is processed by an operational circuit which supplies a noise-reduced output signal to a first one of two series-connected one-frame delay elements and which compares the input video signal with an output signal from the first 1-frame delay element, to execute noise reduction. A degree of noise reduction executed by the operational circuit is controlled in accordance with the degree of correlation between the output signal from the second 1-frame delay element and the input video signal, such that the degree of noise reduction is made small or zero when the correlation is below a predetermined level, indicating the presence of motion components in the video signal. Due to the 2-frame delay used in judging that degree of correlation, the judgement will not be adversely affected by interference components of the video signal which result from interaction between the chroma and high-frequency luminance components of the video signal, when there are no motion components in that signal.

A device detects a correlation between frames represented by a video signal of an interlaced scanning format. A sudden motion of an object represented by the video signal is detected on the basis of the detected correlation. A normal motion of the object represented by the video signal is detected on the basis of the detected correlation. Scanning lines represented by the video signl are interpolated with changeable interpolation characteristics. The interpolation characteristics are changed in response to the detected normal motion of the object. The interpolation characteristics are changed in response to the detected sudden motion of the object.

A silicone rubber composition composed of a high-molecular diorganopolysiloxane, a reinforcing silica filler and an organic peroxide as a curing agent is further compounded with a fluorine-containing low-polymeric compound such as poly(chlorotrifluoroethylene) and perfluorinated polyether compound of the formula F--[--CF(CF.sub.3)--CF.sub.2 --O--].sub.v --O--CF.sub.2 --CF.sub.3, in which v is 2 to 100, as well as fluoroalkyl-substituted organopolysiloxanes. The silicone rubber composition can give a cured silicone rubber product having greatly improved resistance against dynamic fatigue as in repeated cycles of stretching and relaxation.

In a two-picture television receiver, a field polarity detection circuit detects field polarity of an image signal of a main picture. A first and a second field memories are capable of writing-in an image signal to constitute a sub-picture for respective fields, and read-out circuit alternately reads-out from the first and the second field memories in response to a polarity detection signal of the field polarity detection circuit. A write-in field determining circuit determines into which of the first or the second field memories (2), (3), the image signal for the sub-picture is to be written. This writing is based on the polarity detection signal of the field polarity detection circuit, a vertical synchronization signal in image signal of sub-picture, and a binary signal which changes alternately for respective one field based on the vertical synchronization signal. With this receiver, even a non-interlace image signal can be written, respectively, in the first and the second field memories, and a good quality image of two-pictures can be obtained.

A process for processing a silver halide color photographic material is disclosed. The process particularly relates to bleaching and fixing of a color developed silver halide color photographic material. The color developed material is processed with an acid bleaching solution containing a ferric salt, inorganic salt and a halide. Immediately after the bleaching step, the photographic material is processed with the fixing solution containing 5 g/l to 50 g/l of polycarboxylic acids. By utilizing the bleaching and fixing steps disclosed it is possible to process a silver halide color photographic material rapidly utilizing a reduced number of baths, obtain an excellent bleaching rate and produce an image having excellent stability.

The Gramophone record cleaner proposed is of the roller type having a sticky surface formed of a rubbery organopolysiloxane elastomer having a relatively low hardness and adapted to pick up dirt or dust and other contaminants from within the grooves of a record as the roller is passed over the record surface. The roller-type cleaners are superior in their easy performance of complete dirt removal in repeated operations, since the sticky surface of the roller once choked with contaminants can be cleaned simply by rinsing with water.
