Abstract: PURPOSE: To shorten the working time and restrict runaway phenomenon, by welding with two welding heads from the both ends of multiple spot work successively to the middle, shifting one head to the middle, then subsequently welding while moving in the same direction.  
     CONSTITUTION: All spot rows of multiple spot work W are divided into two  groups, and welding is started simultaneously with right and left welding heads  from the corresponding spot (a or e) of row L 1  and row R 1  at the both ends of the  work W. For example, when starting spot-welding from L 1a  and R 1a , the both  welding heads are moved toward the middle of the work W in the direction of  arrow S. By welding an arbitrary number of spots by this preliminary process, one  head is moved to a next spot R 3a , while the other head is moved to spot L na  corresponding to R 3a  in the middle spot row in the left spot group. After welding the  both spots at the same time, the remaining spots are welded, for instance, by  moving the both heads in the same direction as shown by the arrow of broken line.  In the case of work having an odd number of spot rows, the final one spot row is  welded by a single head.

Title: Device for diagnosing crank angle sensor
Inventor: KANEGAE HIDETOSHI
IPC: G01M15/04
Filed: 1979-04-24
Abstract: PURPOSE: To simply diagnose whether a crank angle sensor is normal or not, by judging whether the frequency ratio of reference pulses to angle pulses for the rotation of a crankshaft is of prescribed value or not.  
     CONSTITUTION: When a crankshaft starts rotating, angle pulses S 2  are entered and a reset circuit 13 stops resetting. After that, an FF 7 is set by a reference pulse S 1  and a sixty frequency divider 8 is enabled to perform counting by the output signal S 4  of the FF 7. The frequency divider 8 is made of a counter. Whenever sixty pulses S 2  are applied to the frequency divider, it produces a carry signal S 6  which is applied as an input CLK to a counter 10. As for a crank angle sensor which produces a pulse S 1  in every crank agnle of 120° and a pulse S 2  in every crank angle of 2°, the signal S 7  of the counter 10 having counted the pulses S 1  and the signal S 8  of the counter 10 having counted the signals S 6  are always coincident with each other if the sensor is normal. At that time, the signal S 9  of a digital comparator 11 for comparing the signals S 7 , S 8  with each other has a high level. The AND of the signals S 9 , S 4  is taken by an AND circuit 14 to generate a judgement signal S 10  whose level is high when the sensor is normal.

Abstract: PURPOSE: To secure the connection with the DMA (direct memory access) units featuring different data transfer widths by switching these transfer widths.  
     CONSTITUTION: The IOC (input/output control unit) board 5, 6 and 7 containing the DMA feature both 16 and 32 bits, and mode control line 8 is provided to distinguish these bits. When the 32-bit DMA channel performs the reading/writing of memory 2, line 8 is set to "0" level. The 16-bit DMA channel has no mode control line, and thus no change occurs for the control line when the reading/writing is  carried out for memory 2. The control line features the wired OR structure using the pull-up resistance and is usually set to "1". Accordingly, the bus operates in the 16-bit mode with connection of the 16-bit DMA channel to the information processor.
