Title: Transmitting pulse control device for ultrasonic diagnostic device
Inventor: YOSHIKAWA YOSHIHIRO
IPC: A61B8/14
Filed: 1988-12-16
Abstract: PURPOSE:To provide possibility of obtaining a transmitting pulse signal in high precision by emitting a clock signals with n-phase, selecting a clock signal with a certain phase out of these n-phase clock signals, counting these signals, and thereby eliminating setting error of the delay time. CONSTITUTION:When a start signal for indication of diagnostic image is supplied to a main control circuit 30, an n-phase clock generating circuit 22 is put in operation to emit for ex. a four-phase clock signal. A clock selector circuit 24 selects a clock signal with specified phase set on each of the vibrators 10 in the number of pieces (n). As this clock signal with specified phase, the third phase clock signal is to be selected in case a delay time T of 680nsec is given, and this becomes clock signal with different phase according to the vibrator 10. The clock signal with specified phase is supplied to a counter 36, and the clock is counted, and in case the delay time is 680nsec, the count number 9 is counted down. When the counting becomes zero, a trigger generating circuit 28 is actuated to give a trigger signal with a specified number of pulses to a high voltage pulse generator circuit 12.

Abstract: PURPOSE:To enable measurement of a strength of coke under conditions the most similar to actual operation by measuring the strength using a sieve after a load is applied to coke within a housing box to vibrate to evaluate a powdering behavior when it drops. CONSTITUTION:A bottom wall 7 is closed, a specified amount of coke 1 to be tested is housed into a coke housing box 2 and a weight 3 is placed on the top thereof to apply a specified load to the coke 1. Then, a pair of vibration side walls 5 of the housing box 2 is vibrated with a driving mechanism 11 for a fixed time length at a specified frequency and amplitude. Thereafter, the bottom wall 7 is opened to discharge the coke 1 from the housing box 2. Then, the coke 1 discharged is sieved and a proportion thereof on the sieve is measured to determine a powdering, namely, strength thereof. With such an arrangement, when the coke falls within a blast furnace, a powdering behavior generated by a shear stress is evaluated. This enables measurement of the strength of the coke under conditions the most similar to actual operation.
