A piping travelling apparatus having a plurality of continuous treads driven by motors through transmission gearing. The continuous treads are mounted to a frame and spaced apart a predetermined distance peripherally of the inner wall surface of the piping. At least one of the continuous treads is kept in contact with the inner wall surface of the piping no matter what the posture of the apparatus may be, so that the apparatus can travel without any trouble even if its posture undergoes a change when it moves along elevations and depressions on the inner wall surface of the piping or negotiates the boundary between different levels of the inner wall surface or bends of the piping. The apparatus enables a travel through piping of relatively small diameter having vertical or steeply slanted pipes to be made without any trouble.

A chain-like self-moving robot includes three or more capsule units connected to one another in a string by means of couplers. By expanding and contracting intercapsule spaces in a predetermined sequence so that a smaller number of the capsules are moved while a larger number of capsules remain stationary, the chain-like robot can move forwardly or backwardly.

In an image formation system which includes a finisher with an inserter having a tray for stacking the specific sheet on which an image such as a cover image was formed, and an image formation apparatus, a series of originals composed of plural pages is read from its head page in due order, the image based on the read original is formed on the sheet, the sheet stacked on the inserter is fed, the sheet from the inserter is reversed to set its image-formed face facedown, the sheet from a printer unit is reversed to set its image-formed face facedown. The sheet, the image-formed face of which was reversed facedown, is discharged from the printer unit to the finisher and, on the finisher, the sheet from the inserter is stacked as keeping its image-formed face facedown and the sheet from the printer unit is stacked as keeping its image-formed face facedown. The top and bottom of the image formed by the image forming apparatus corresponds to the top and bottom of the insert sheet.

A sheet sorting apparatus includes a plurality of trays for accommodating sheets; a helical cam device, engageable with a cam follower for moving the plurality of trays; a cam driving device for driving the helical cam device; a sheet set processing device movable between processing position and a retracted position where the processing device doe snot interfere with the plurality of trays; a reversible driving device for advancing or retracting the sheet set processing device; and a controlling device for controlling the driving device; wherein a cam surface of the helical cam is constituted of substantially horizontal portions and slanted portions; and the cam driving device and the driving device are controlled by the controlling device, in such a manner that the sheet set processing device starts to enter a processing position when the cam follower shifts from the slanted portions to the horizontal portions, and the entering operation ends by the time the cam follower reaches the middle portion of the horizontal portion, and that the cam driving device is deactivated when the cam follower is substantially at a middle portion of the horizontal portions, and after sheet set processing, the cam driving device and the driving device are actuated, and the sheet set processing device is retracted from a moving path region of the tray by the time the cam follower passes through the remaining portion of the horizontal portions.

A video signal reproducing apparatus is provided with a memory which is capable of storing a portion of a video signal covering a predetermined period of time and is arranged: To allow a record bearing medium on which the predetermined period portion of the video signal is recorded in each of many recording tracks formed in parallel to travel at a given speed different from a speed employed in recording; and to decide whether or not each of the video signal portions reproduced by a reproducing head is to be stored by making the decision on the basis of the signal reproduced from each of the tracks by the reproducing head.

A circuit for supplying weighting voltages to multipliers of a transversal filter comprises a plurality of electronic switches associated with the multipliers for switching magnitudes of the weighting voltages applied to the multipliers, and memory cells associated with the respective electronic switches for storing digital data to turn on or off the corresponding electronic switches. Those memory cells are sequentially addressed by address circuits to store data which define the magnitudes of the weighting voltages applied to the multipliers.
