Abstract: A vertically arranged plurality of trays are each formed with a cut-out at a rear corner. The trays are arranged so that the corner where the cut-out is formed is lower than the other corners. Vertically upward extending rear and side walls are provided on each tray adjacent the cut-out. A downwardly extending side wall is formed on the tray opposite the upwardly extending one. The trays can be selectively shifted by cylindrical cams to positions wherein sheets of printed matter can be ejected thereonto. Due to the skewed angle of the trays the sheets slide to the corners where the cut-out are formed. After sheet collation a tray drawing device pulls a tray rearwardly to a stapler which fastens the sheets at the corners which extend into the cut-out. The tray drawing device then returns the tray, the trays are shifted vertically by the cylindrical cams, and the next tray is pulled to the stapler.

Abstract: A sorter includes a plurality of vertically movable trays which are each formed with a cut-out in one corner. The trays are supported so that the corners in which the cut-outs are formed are lower than the other corners of the tray. Rear and side walls flank the cut-outs. Due to the skewed angle of the trays sheets which are ejected thereonto slide under their own weight to the corners in which the cut-outs are formed. A tray shift mechanism includes groups of two Geneva wheels each formed with one or more recesses which can pick-up tray pins and guide the same along guide slots. The guide slots are formed with shaped portions which induces one tray at a time to be moved laterally to a position wherein sheet collection or stapling can be carried out. A spring loaded stopper cooperates with each set of two Geneva wheels and holds the pins which have been carried to a laterally displaced position by one wheel, against the periphery of the wheels ready for pick up by the other wheel.

Abstract: A first moving member is arranged on a base for reciprocal movement in an article transporting direction. A second moving member is arranged on the first moving member for reciprocal movement in the article transporting direction. The second moving member is adapted to contact each receptacle which is being transported to an operation position to which receptacles carrying articles to be treated are sequentially transported. A first biasing mechanism biases the first moving member in a direction opposite to the receptacle transporting direction. A second biasing mechanism biases the second moving member in a direction opposite to the receptacle transporting direction by a biasing force smaller than a biasing force of the first biasing mechanism. Pressing arm is mounted on the first moving member for movement toward and away from the articles to be treated on each receptacle at the operation position.

Abstract: An error correction method and circuit for a nonlinear quantization circuit comparing a test signal which is produced from an error correction table by applying an analog reference signal into a nonlinear circuit with reference data that is defined as an output of the error correction table when the nonlinear circuit has no error, and updating the error correction table by the test signal and the reference data when they disagree. The output of the nonlinear circuit is corrected by using the error correction table. The technique is particularly suitable for nonlinear conversion performed by a gamma correction circuit of a color television camera.

Abstract: A transporting device for articles to be transported and a sorter with the same. The transporting device includes transporting rollers arranged in a transportation passage so as to contact the articles to be transported for transportation in a forward direction. The transporting rollers are supported for rotation about an axis which is swingable in a substantially horizontal plane. The axis of each transporting roller is selectively changed by a direction changing mechanism between one direction to transport the articles to be transported in the forward direction and another direction to obliquely transport the articles to be transported toward a side wall. The side wall is provided along the forward direction at an article reception position in the transportation passage.

Abstract: A sorter includes a plurality of vertically movable trays which are each formed with a cut-out in one corner. The trays are each oriented so that a corner in which the cut-out is formed is lower than the other corners of the tray and formed with a rear wall a side wall which flank the cut-out. A tray shift mechanism includes groups of three Geneva wheels. These wheels are each formed with one or more recesses which can pick-up tray pins and guide the same along guide slots. The slots are formed with portions which induce both vertical and lateral displacement of one or more trays at a time. The Geneva wheel/guide slot arrangements move the trays one by one to a position wherein sheet of printed matter can be ejected thereonto and/or the cut-outs are located in the mouth of a stapler. Due to the skewed angle of the trays the ejected sheets slide under their own weight to the corners in which the cut-outs are formed.

Abstract: A circuit for correcting a tone of a brightness signal generated by a television camera including an upper limiter for clipping off an upper portion of the brightness signal higher than an upper threshold level, and a lower limiter for clipping off a lower portion of the brightness signal lower than a lower threshold level which is automatically changed in accordance with a peak value of the black level of the brightness signal. A middle level brightness signal produced by the lower limiter is processeed by a non-linear circuit and then a difference between a non-linearly processed bright signal and the middle level brightness signal is derived to produce a tone correction signal. After the polarity and gain of the tone correction signal are manually adjusted, the tone correcting signal is added to the input brightness signal. In this manner the tone of a television image displayed on a television monitor screen can be corrected exclusively in a dark area without affecting the tone in a bright area.

Abstract: A sorter with a plurality of receptacles arranged vertically movably and being capable of receiving articles to be treated. A drawing mechanism sequentially draws out one of the receptacles to a predetermined treatment position by shifting the receptacles. A treatment is applied by a treatment mechanism to the articles on respective receptacles drawn out to the treatment position. One of the articles is discharged by a discharging mechanism to a lower adjacent receptacle positioned just below the receptacle drawn out. A front portion of each receptacle is guided diagonally upwardly by a guiding mechanism when the receptacle is drawn out, the front portion of the receptacle being remote from the treatment position.

Abstract: A stereoscopic video signal converting apparatus having A/D converters, field memories, and a D/A converter shared by both the parallel processing system and the time-division multiplex processing system. The shared portions are selectively used for either one of the two systems in accordance with an instruction such as a parallel/time-division multiplex selection signal which selects either one of two types of the read and write pulses for the field memories. A suitable processing system of the two types is selected depending on whether a picture quality or one channel transmission is required without increasing a cost of the apparatus. The apparatus provides compatibility between the two systems so that an operability of the system is enhanced.

Abstract: A sorter includes a shifting mechanism for sequentially shifting the receptacles and for holding each receptacle shifted in an open position in which the articles to be treated may be placed on the receptacle. The shifting mechanism is provided with a pair of Geneva wheels each having at least one groove formed therein on a predetermined phase condition. The shifting mechanism further includes a first guide slot to vertically movably align and guide the pins of each receptacle, and a second guide slot continuous to the first guide slot, the second guide slot being adapted to laterally guide a pin of one of the receptacles for drawing out the one receptacle. The pin of the one receptacle is biased by a biasing mechanism against the outer circumferential surfaces of the Geneva wheels. The receptacles are received in a receptacle carrier, and the receptacle carrier is vertically movably arranged.
