Title: Seismoscopic interrupting device
Inventor: EGUCHI OSAMU
IPC: G01V1/16
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To miniaturize the device and improve the flow measuring precision by providing a plurality of passage opening and closing means for opening and closing a plurality of passages and closing the passage opening and closing means other than the passage having a flow measuring means when an earthquake is detected. SOLUTION: When both passage opening and closing means 2a, 2b are in open state, a fluid is carried to respective passages 1a, 1b in a ratio determined by the structure of the passages 1a, 1b. Since a flow measuring means 3 detects the flow rate of the fluid carried in the passage 1b, the whole flow rate can be determined by multiplying the flow rate value measured by the flow detecting means 3 by the flow ratio of the passages 1a, 1b. When an earthquake is detected by a vibration detecting means 5, a control means 4 closes the passage opening and closing means 2a other than the passage 1b having the flow detecting means 3. Then, the fluid is entirely carried to the passage 1b, and the total flow rate is measured by the flow measuring means 3.  The total flow rate is measured by the flow measuring means 3 after the occurrence of the earthquake to judge whether the leakage of the fluid is caused by the earthquake or not, whereby a precise detection can be performed even in a small flow rate.

Abstract: PURPOSE:To prevent the interaction between adjacent magnetized poles by inserting a cylindrical magnetizing magnetic pole to a hollow part, pressing the other magnetizing magnetic pole to the circumference of the core so as to apply insert forming thereby projecting the core circumferential face. CONSTITUTION:In recording a signal on a tape 1, since the tape 1 is run while being pressed to a core 5 of an erasure head 4, the recording is erased by being magnetized saturatingly by an erasure magnetic field of the core 5 and recorded newly by a recording/reproducing head 3. The 1st-3rd magnetized magnetic poles 10-12 are formed to the core 5 by the magnetizing magnetic field generated between the magnetic poles 11, 12 and the magnetic pole 13 in flowing a magnetizing current I to a coil 9 of a magnetizer 8. Since the 4th magnetic pole 13 as a counter pole is provided to the magnetic poles 10-12 magnetizing the magnetizing magnetic poles to the magnetizer 8, the magnetizing magnetic field is applied perpendicularly to the circumferential face of the core 5 and the magnetization without leakage of magnetization and interaction between adjacent magnetizing magnetic poles is attained.
