Title: Method and apparatus for measuring the number of stacked corrugated cardboards
IPC: G06M9/00
Filed: 1974-12-30
Abstract: 1497269 Measuring the number of stacked corrugated cardboards NIHON ELECTRONIC INDUSTRY CO Ltd 30 Dec 1974 [28 Dec 1973] 56041/74 Heading G1A [Also in Division G4] Apparatus for this comprises photo-electric sensor means 14 for scanning vertically one side of the stack while repetatively horizontally scanning it and having a horizontal row of sensor elements to receive reflected light and means 8 for energizing each sensor element in turn and means 10, 11 for detecting from the sensor output signals whether a scan is of a base sheet or a corrugated sheet and means 13 for analyzing these detections to determine the number of corrugated cardboards in the stack. For the vertical scan light sources 32, 33 may move with means 14 or illuminate the whole side provided that each photodiode of means 14 views a small area. When the sixty four photodiodes are energized sequentially by control pulse generator 8, if they are opposite a base sheet or a corrugated sheet the output from flip-flops 18, 19, 20 is pulse patterns 5 and 6 respectively. This is applied to shift registers 21, 22 with sixty four bits so that OR gate 42 responds to any existing signal or one from the same photodiode in the two preceding horizontal scans, to feed counter 23 via AND gate 43. Counter 23 recounts for less than twenty consecutive bits input and produces an output of 1 for more, indicating a base sheet, to flip-flop 26 through OR gate 44. AND gate 45 produces an output 1 only when it receives two consecutive signals from circuits 19 and 20 indicating a crossing point of a corrugation. Counter 24 gives an output when the number of crossing points exceeds four and when it does this for more than three consecutive scanning cycles, counter 25 gives an output 1. Zero detector 12 indicates a gap in the stack by giving a 1 output when there are no consecutive signals from circuits 19 and 20 during one scan. Flip-flop 26 is set by a 1 input from detector 12 or base detector 10 and reset by the output from counter 25, and so each time the edge of one corrugated cardboard is traversed vertically it produces an output to counter 27 decoder 28 and display 29.

Abstract: 1322110 Semi-conductor devices COMMISSARIAT A L'ENERGIE ATOMIQUE 31 Dec 1971 [14 Jan 1971] 60988/71 Heading H1K A charge coupled device uses only two groups of electrodes, 1, 3, 5 and 2, 4 &c. respectively to transfer charges within the device by making use of ion implanted dopants in the semiconductor substrate 16<SP>1</SP> below and between the electrodes. To prevent charges moving "upstream" on transfer, the "upstream" edge of each subjacent electrode region has a greater impurity concentration, of the same conductivity type as is prevelent in the substrate as a whole, than the remainder of the region. This concentration is caused by ion implantation at angles between 10 and 30 degrees to the substrate surface to form regions 20<SP>1</SP>. To aid rapid charge transfer the interelectrode substrate regions are counterdoped by ion implantation directed perpendicularly to the substrate surface to form regions 22<SP>1</SP>. This structure enables two trains of clock pulses, P 1 <SP>1</SP>, P 2 <SP>1</SP> applied to the electrodes as shown to cause charge transfer, each clock being capable of three voltage levels, a level V 1  for electrodes not holding or attracting charge, a higher level V 2  for electrodes storing charge, and a higher level V 3  for electrodes attracting charge. The substrate may be of silicon with phosphorus and boron doping, the insulating layer 18<SP>1</SP> being of silicon dioxide, the electrodes, aluminium.
