IPC: G01S7/52
Filed: 1987-07-13
Abstract: PURPOSE:To vary a detection area and a detection distance by connecting variable delay circuits to plural array elements respectively. CONSTITUTION:An ultrasonic wave signal from an oscillator 11 passes through a power amplifier circuit 12 and a variable delay circuit 13 and drive respective array elements 2a-2d of the transmitter 2 in the transmitter 2 and receiver 3 comprising the plural array elements. At this time, ultrasonic wave signals supplied from the circuit 13 to the elements 2a-2d are delayed by respective different quantities. Then the receiver 3 receives the ultrasonic waves and electric signals generated by array elements 3a-3d are delayed by respective different quantities through a variable delay circuit 14, superposed one over another, and inputted to an amplifier circuit 15. Then the delay quantities of the circuits 13 and 14 are controlled with the clock frequency of the oscillator 18 and then even when the transmitter 2 and receiver 3 are arranged on the same plane, respective ultrasonic beams, i.e. detection areas can be made to cross one another in front of an ultrasonic wave sensor.

IPC: B21B1/08
Filed: 1993-07-14
Abstract: PURPOSE:To enlarge a regulating amount of a roll width by fitting a hollow shaft onto a roll shaft movable in the axial direction, joining the rotational direction with a sliding key. and installing a hydraulic cylinder for regulating the roll width inside the hollow shaft just nearby the fitting part of the roll shaft and the hollow shaft. CONSTITUTION:A hollow shaft 3a is fit onto a roll shaft 1 movable in the axial direction, and the rotational direction is joined with sliding keys 4a, 4b. Because a hydraulic cylinder 6 for regulating the roll width is installed inside the hollow shaft just nearby the fitting part of the roll shaft and the hollow shaft, the total length of roll is the same as one body roll of the same structure. Further, because the shaft length of the hollow shaft 3a requiring highly precise machining is short, the equipment cost is also in-expensive. More, because a composite roll width regulating device between respective hollow shafts, and between the hollow shaft and roll bearings is needless, the restriction to regulate the minimum roll width and the maximum roll width is a few, on the result, the regulating amount of the roll width can be enlarged.
