  • Patent number: 12036069
    Abstract: An ultrasonic diagnosis system includes a reaction force detection sensor that detects a reaction force acting on an ultrasonic probe when the ultrasonic probe is pressed against a body surface of a subject. Then, the ultrasonic diagnosis system estimates the push-in amount of the ultrasonic probe with respect to the subject by using the reaction force detection sensor during the ultrasonic diagnosis to output a display or a warning of the estimated push-in amount of the ultrasonic probe to the output device.

  • Patent number: 12036526
    Abstract: Improvement in the efficiency of carbon dioxide reduction reaction is achieved. A gas supply unit having a plurality of pores is established in a lower portion of a reduction chamber, and carbon dioxide is supplied as bubbles into an aqueous solution. This can elevate a concentration of carbon dioxide dissolved in the aqueous solution without stirring the aqueous solution using a stirring bar, and render the concentration uniform in the aqueous solution. Therefore, the efficiency of reduction reaction of carbon dioxide in a reduction electrode can be improved.
