Abstract: PURPOSE:To permit a customer not to pay the charge for the use of a circuit in case of a defective recorded picture by discriminating a defective recordded picture if the frequency of error occurrence is high even when the number of error lines is less than a specified value. CONSTITUTION:A decoding circuit 2 outputs an addition signal 12 to a counting circuit 4 for the number of successive error lines to increase a counted value 1. Once decoding for one line is carried out normally, the counted value is reset by the decoding circuit 2. The counted value of the counting circuit 4 is inputted to a comparison and discrimination circuit 6; when the counted value is greater than the specified value, a defective recorded picture detection signal is supplied to a display circuit 11 through an OR circuit 10. A reset signal from a decoding circuit 2 is supplied to a counting circuit 7 for the frequency of occurrence of line error and its counted value is supplied to a comparison and discrimination circuit 9. When the frequency of error occurrence for a specified number of line is greater than the specific value, the defective recorded picture detection signal is supplied to the display circuit 11 through the OR circuit 10.

Filed: 1984-04-20
Abstract: PURPOSE:To prevent interruption of processing due to forgetting of channel mounting when a processing system is operated, by sending I/O instructions to individual I/Os and searching control channel numbers of no response to enter them in an I/O management table. CONSTITUTION:Before the system is operated, an I/O control program 11 is executed. Then, a processing part 8 sets flag ''1'' in the term of a chennel number C1 of a column L2 in a table T by a response signal D1 from a control channel CH1 of a mounted printed board, and a register 12 is updated. A processing part 7 issues a read instruction R2 to a channel CH2 on the basis of an updated address A1 of the register 12. If a printed board PT2 is not mounted, the response is not transmitted from the channel CH2. A monitor part 13 sends a no-response signal D2 to the processing part 8 after a prescribed time and sets flag ''0'' in the term of a channel number C2 of the column L2 in the table, and the register 12 is updated. After this control, flags indicating whether printed boards are mounted or not are set in terms of channel numbers C1-Cn of the table T.

Abstract: PURPOSE: To heat the slab of extremely less skid marks with good thermal efficiency by making the hearth metals of the heating furnace by pipes of heat-resisting steel and cooling the same according to need in the case of heating the slabs of copper and special copper alloy to different temperatures.  
     CONSTITUTION: In a walking beam type heating furnace 1 which heats a slab 3 of Cu or Ni-Cu, its stationary beams 6 and the stanchions 4 thereof, walking beams 9 and their stanchions 8 are made of pipes of 25Cr-20Ni heat-resisting steel. The heating temperatures of the Cu slab are 850W900°C, and the heating temperatures of the Ni-Cu-alloy are 1,000W1,015°C. The service limit temperatures of the Cr-Ni- base heat-resisting steel are 950°C or less. Hence, in the case of heating the Cu slab, both beams and others are not cooled, hence do not cause any heat loss and are not put with skid marks. At the time of heating the Ni-Cu alloy slab, both beams are cooled and are kept at 880W950°C, but there is no need for cooling them down to about 400°C as with beams made of mild steel and therefore there are less heat losses owing to the cooling and the skid marks decrease considerably.
