Title: Ultrasonic image pickup device
Inventor: MIWA HIROHIDE
IPC: G01S7/52
Filed: 1980-07-29
Abstract: PURPOSE:To enable the transmission and reception to be performed at the same time even through central frequencies are close to each other, by modulating vibrating units which have different frequencies and a plurality of electricity-sound transducer elements, transmitting ultrasonic signals, and separating the received signals by a matching filter. CONSTITUTION:The output of an up-chirp wave oscillator 100 whose frequency is fo drives the vibrator 106 via a driver 102 and a switch 104. The ultrasonic wave T1 is sent to the inside of a body to be checked A, and reflected by an internal organ C. The reflected signal R1 is received by the vibrator 106. The received signal is outputted from the matching filter 110 through the switch 104, and receiving circuit 108. The output of a down-chirp wave oscillator 101 whose frequency is f1 is transmitted and received in the same way. The switching of transmission and reception are performed by the control of a timing circuit 112 at the same time. Therefore, e.g., cross talk N2 of the wave f1 is inputted to the receiving circuit 108, but it is attenuated by the matching filter 110 since the direction of the chirp modulation is different. Even though the frequencies f0 and f1 are close to each other, interference is not caused, and this is suitable for the image pickup of the inside of a human body.

Title: Instantaneous photodetecting circuit
Inventor: MATSUDA MOTONOBU
IPC: G01J1/44
Filed: 1979-08-16
Abstract: PURPOSE: To make possible the detection of instantaneous light without being affected by the intensity of steady light by providing an electric current control circuit allowing the passage of only the photocurrent of the steady light and an electric current circuit receiving pulse-form photocurrent.  
     CONSTITUTION: An electric current control circuit is formed by a transistor TR31, a buffer circuit 33 for negative feedback and a capacitor 34 for delaying and allows the passage of only the steady light from a photoelectric element 30. Now, when the pulse-form photocurrent superposed on the steady light from the element 30 inputs, the TR31 allows the passage of the steady light but blocks the passage of the pulse- form photocurrent. Hence, the pulse-form photocurrent is supplied to the base of the TR35 in which constant current is flowed by a constant current source 36. As a result, the impulse-form photocurrent is taken out as the collector current amplified by the TR35 irrespective of the intensity of the steady light. In this way, the instantaneous light may be taken out.

The larger the changes in the intensity of a magnetic field to reach are, the larger an induced electromotive force that the secondary coil 3 generates is. As the magnetic permeability of space is small and the magnetic permeability of molten steel 4 is large, the size of an induced electromotive force generated at the secondary coil 3 is changed according to the changes in the level of the molten steel 4. In other words, an induced electromotive force corresponding to the level of the molten steel 4 is generated at the secondary coil 3. By detecting the induced electromotive force, it becomes possible to detect the level of the molten steel 4 in the immersion nozzle 1.
