A diagnostic imaging apparatus is disclosed in which an ultrasonic wave transmit/receive apparatus is used in common for both 2-dimensional B-mode imaging and for measurement of pulsed Doppler signals, by time sharing operation. The good real time characteristics of 2-dimensional B-mode imaging are retained, together with a sufficiently high data rate for pulsed Doppler measurement, through use of...

A fuel filter includes a housing made of plastics and having a main housing portion accommodating a filter element, and a cover. The housing portions are tightly connected to each other at a single ring-shaped glue spot. The housing portion is formed with a pocket filled with glue and the cover is formed with a collar partially projecting into the pocket to form an annular Z-shaped gap in which th...
