Abstract: A high-side driver has a semiconductor element being connected in series in a power supply path extending from a DC power source to a linear solenoid and turned on/off to control a current of the linear solenoid. The high-side driver includes a current detector of a current of the linear solenoid, a controller of the semiconductor element, a state detector of the high-side driver or the linear solenoid and output a state signal, a first transmit buffer to latch and output the state signal, a second transmit buffer to output the state signal without latching the same, and a transmit shift register to convert the state signal into serial data and transmit the serial data to an external device at predetermined timing. The state detector selects at least one of the first and second transmit buffers and outputs the state signal to the selected one.

Abstract: This disclosure relates to an endless belt comprising a bed of elastic material and a plurality of longitudinally extending tension cords embedded therein. Each of the cords has its ends interconnected to form a junction, and the junctions of the cords are distributed over the length of said belt so that the junctions are longitudinally offset.The disclosure further relates to a process of producing such an endless belt.

Abstract: A safety device for a conveyor belt which comprises a pair of magnets buried in a joint of a belt or buried in the belt with the joint therebetween, with a certain space left therebetween in the lengthwise direction of the belt, a magnetic inductor arranged oppositely to said magnets, an oscillograph connected to said magnetic inductor for self-recording or a detecting device connected to said magnetic inductor for detecting any elongation at the joint in its early stages.
