Title: Body step detecting device
Inventor: WATANABE KATSUMI
IPC: G01B17/00
Filed: 1988-03-09
Abstract: PURPOSE:To enable step detection on the plane of a transparent body and in environment wherein there is much dust by projecting an ultrasonic wave on two parallel planes having a step and detecting interference which occurs owing to the phase difference between two reflected ultrasonic waves generated by said step. CONSTITUTION:The ultrasonic wave S1 is intermittently emitted by a vibrator 7 while its frequency (f) is set to a specific value. Namely, the wave is emitted by, for example, five cycles for longer than the going and return time T found by distance between the vibrator 7 and both planes 5a and 5b, and caused to stroke on the planes 5a and 5b. Then, the reflected wave S2 which strikes on the plane 5a returns to the vibrator 7 the time T later as shown by a solid line and the reflected wave S3 which strikes on the plane 5b returns to the vibrator 7 as shown by a dotted line while shifting by 2L=lambda/2 out of phase with the reflected wave S2. The ultrasonic vibrator 7, therefore, causes interference, so even if it is amplified by an amplifying circuit 8, its output is almost '0' and an interference detecting circuit 9 performs detection so that the step size L is a specific value.

Abstract: PURPOSE:To make the overall installations significantly smaller by providing multiple reservoirs for storing the thermal medium and by sequentially switching the feeding and storing of a low temperature fluid or a high temperature fluid so that a compact reservoir may be used in spite of a large capacity heat accumulation installations. CONSTITUTION:The reservoir storing a thermal medium is divided into multiple reservoirs 21a, 21b, 21c, 21d. Under such a condition that one reservoir 21e among them is empty and the rest of the reservoirs 21a, 21b, 21c, 21d are filled with a high temperature thermal medium, the cold-heat of the LNG is recycled and accumulated. First, the high temperature medium in the reservoir 21a passes through a pipe 24a, pipe 4 and pump 5 to be fed to an LNG vaporizer 2 to exchange the heat with the LNG fed through a pipe 1, and after cooled to become a low temperature thermal medium it is supplied to the empty reservoir 21e. When the reservoir 21a becomes empty, the reservoir 21e is completely filled with the low temperature thermal medum. Next, the high temperature thermal medium in the reservoir 21b is fed to the LNG vaporizer 2 to be reduced to the low temperature medium and is supplied to the empty reservoir 21a. This process is repeated by sequentially changing the reservoir, and the high temperature medium is all reduced to be the low temperature thermal medium to be stored in the reservoirs 21a, 21b, 21c, 21e.
