IPC: G01S7/52
Filed: 1981-06-22
Abstract: PURPOSE: To increase the directional resolution over the entire part of a section image,  by extracting only the reflected echo near the focus of an ultrasonic beam by the focal  region gate signal which moves in accordance with the depth of focus.   
     CONSTITUTION: The oscillator groups 2 of an array type probe is shifted one by one,  and a fan-shape scan is carried out by the focused ultrasonic wave beam having the  variable incident angle. Then the signals having different phases and received from the  corresponding ultrasonic wave receiver groups are led to a delaying circuit 15, and the  delay time equivalent to that of the transmitter side is given so as to be coincident  with the center beam of the ultrasonic wave receiver. The output of the circuit 15 is  turned into the original waveform by an adder 16 and then receives the wave detection  through a wave detector 17. The focal region gate position setting signal corresponding  to each set incident angle is delivered to a focal region gate setting circuit 18 from a  main control part 5 via a control bus. Then the operation is started and stopped at the  focal region gate starting point and with the set value within the focal region gate  range. The propagation time of the ultrasonic wave is limited, and only the reflected echo received at the area near the desired focal point is extracted a gated video signal.

Title: Continuous sheet metal treating line capable of double cold rolling-double annealing
Inventor: FUJITA TAMIO
IPC: C21D9/56
Filed: 1995-04-20
Abstract: PURPOSE: To lower a rolling load and to stabilize a shape by arranging continuously primary annealing equipment for heating a sheet metal to a recrystallization temperature or over and cooling, secondary cold rolling equipment and secondary annealing equipment behind hot rolling, pickling and primary cold rolling equipment. CONSTITUTION: Scales of a hot rolled coil discharged from hot rolling equipment 1 are removed by pickling equipment 2, and the hot rolled coil is rolled to a desired plate thickness by primary cold rolling equipment 3. Next, primary annealing equipment 4, secondary rolling equipment 5, and secondary annealing equipment 6 are continuously arranged. The coil after the primary cold rolling is heated by the primary annealing equipment 4, but the coil requiring double cold rolling is recrystallized by heating to a recrystallization temperature or over by the primary annealing equipment 4, and is sent to the secondary rolling equipment 5. In the secondary rolling equipment 5, the coil is rolled after the recrystallization, and is annealed by the secondary annealing equipment 6.  However, the coil not requiring the double old rolling is passed through by opening the rolls of the secondary rolling equipment 5. Consequently, since rolling under a high pressure is not necessary in the primary cold rolling, the fracture of a plate can be suppressed and a shape can be stabilized.
