摘要:
An apparatus for detecting surface irregularities in a moving web is disclosed. The apparatus includes a laser light source, the output beam of which is divided into a plurality of zone scanning beams by an optical network. The plural beams are reflected by a rotating scanner to a series of reflecting surfaces, each oriented at a different angle to stagger the scanning beams. The staggered beams are again reflected from two groups of reflecting surfaces inclined in opposite directions relative to one another for separating the scanning zones covered by the scanning beams.

A time division multiplex system adaptable for branching services, which includes a predetermined level code generator for generating a signal of the same level and a switching unit for switching between the predetermined level signal and a signal to be multiplexed. The channel bit group number allotted to each channel is changed with time. For signals of transmission speeds above 64 Kb/s, a plurality of time slots are used to form a single channel to thereby accommodate branching services in octet units.

摘要:
Disclosed is a surface defect detecting apparatus comprising a scanning device for scanning a rolled steel plate rolled and transferred by a pair of rolls at a fixed period over its full width to successively produce signals representing a surface condition of the rolled steel plate over the full width thereof, and a defect signal generating circuit for producing output signals representing the presence of a surface defect on the surface of the rolled steel plate in accordance with output signals from the scanning device. The surface defect detecting apparatus is further provided with a pulse generator for producing pulses every rotation of the roll, a memory, a display unit, and a control system which responds to output pulses from the pulse generator to sequentially write defect signals generated from the defect signal generation circuit into the memory, reads out the data from the memory after the memory is full up with the data, and causes the display unit to display on one line the data obtained every rotation of the roller.
