Abstract: PURPOSE:To reproduce a normal sound signal even when only the sound signal is recorded and reproduced by oscillating a variable frequency oscillating circuit, which is forcibly triggered by a vertical synchronizing signal, with an oscillation frequency lower than the vertical synchronizing signal frequency when the vertical synchronizing signal exists. CONSTITUTION:A video signal is inputted to an input terminal 1 and has a vertical synchronizing signal S1 extracted by a vertical synchronizing signal separating circuit 2, and the output signal S1 of the vertical synchronizing signal separating circuit 2 is inputted to a vertical synchronizing signal detecting circuit 11 and a variable frequency oscillating circuit 12. If the vertical synchronizing signal S1 exists, an output signal S11 of the vertical synchronizing signal detecting circuit 11 is set to the low level; and if the vertical synchronizing signal does not exist over a prescribed time, this output signal S11 is set to the high level. When the output signal S11 is in the low level, the oscillation frequency is set to a frequency (f0=1/T0) slightly lower than the frequency of the vertical synchronizing signal; and when the output signal S11 is in the high level, it is set to a frequency (f11=1/T11) approximately equal to the frequency of the vertical synchronizing signal.

IPC: G01B17/02
Filed: 1988-02-19
Abstract: PURPOSE:To project ultrasonic waves stably into an object to be detected and also to measure the case depth of said object even when the case depth is small, by using a ultrasonic probe which is able to swing its neck and the distance from which to the surface of said object immersed in water is maintained constant. CONSTITUTION:After a part of an object 1 to be detected is moved above a probe holder 2, the height of a free bearing and the rotation of a probe 21 are adjusted so that the echo at the surface of the object 1 becomes maximum. The waveform of the surface echo of the object 1 after the adjustment is read into a time lag measuring device 92 by instructions from a CPU 94, and accordingly the time Ta since pulses are projected until the surface echo is received is measured and inputted to the CPU 94. Then, the CPU 94, assuming a predetermined incident angle, calculate a delay time Td on the basis of the relational formula. The delay time Td is transmitted by the CPU 94 to a high speed A/D converter 93, whereby the start of the memory is delayed by the time Td from the projection of the pulses. Then, the CPU 94 averages the strength of many backward-scattered waves to obtain the backward-scattering pattern which is outputted to a CRT 96. Accordingly, the case depth is obtained by the discontinuity of the pattern displayed by the CRT 96.

Title: Door
Inventor: MATSUMOTO HIROYUKI
IPC: E06B5/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To contrive to be solid against a force exerted from an outdoor side and reduce resistance to a force from an indoor side by extending two middle rails between upper and lower frames and fixing a web of a continuous long member which is laid out in a groove produced by cutting a front surface board between the middle rails and the upper and lower frames. SOLUTION: A notched groove 6 closes an inlet with a flange 72 and sets up a door 1, thereby hiding the groove 6 from an outside. An external force is applied to the door 1, thereby cutting off a front surface board 3 and upper and lower frames so that the door 1 may bend inwardly, centering on a rear surface board 4. In this case, a web 71 is laid out in the groove 6 produced by cutting the front surface board 3 so that it may strike against both side surfaces. Furthermore, the flange 72 integrated with the web 71 strikes against the front surface board 3, thereby making it difficult to bent the door in the indoor side. The resistance against the force from the indoor side is restricted to the rear surface board 4 alone, thereby weakening the resistance exceptionally.  This construction makes it possible to be solid against the force from the outside and safe for protection purposes and open the door 1, which is otherwise impossible to open due to deformations produced by an earthquake or the like by adding force from the indoor side and evacuate.
