Filed: 1989-07-24
Abstract: PURPOSE:To improve detecting sensitivity without increasing Coriolis force by forming the cross sectional shape of at least the end part of a vibration body in a rectangular shape wherein one side for connecting main surfaces is smaller than the other side. CONSTITUTION:The cross sectional shape of a vibrating body 1 constituting an apparatus is formed in a rectangular shape so that one side for connecting main surfaces 1b and 1d to which supporting members 3a and 3b are linked is smaller than the other side. Therefore, the vibrating body 1 has the structure so that the vibrating body 1 is readily deflected in the detecting direction where the supporting members 3a and 3b are provided. The large deviation between the resonance frequency in the detecting direction generated by the loads due to the supporting members 3a and 3b and the resonance frequency in the driving direction is eliminated. The frequency of Coriolis force and the resonance frequency in the detecting direction are brought close together. Driving in the detecting direction by the Coriolis force is performed efficiently. Thus, the detecting sensitivity can be improved.

Title: Method for predicting danger in constructing of tunnel
Inventor: SHIOZAKI OSAMU
IPC: G01M3/20
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To prevent blows resulting from a leakage of compressed air and oxygen deficiency in the air by mixing a tracer gas in the compressed air, feeding the mixture into a tunnel, and checking the presence/absence of the tracer gas by a tracer gas detector at the ground surface. SOLUTION: When a tunnel is built, compressed air of a predetermined pressure with helium gas mixed is sealed from an upper air lock 3 into a working chamber 2 and the ground is excavated downward in the working chamber 2. In this case, it is enough to mix the helium gas with the compressed air approximately by 1%. A gas in the periphery of a caisson body 1 is sucked at the ground surface by a helium leak detector 6 which is loaded on a cart 7 and thus freely movable. The presence/absence of the helium gas is thus detected. If the compressed air with the helium gas mixed leaks in a stratum 5, the helium gas penetrates the stratum 5 faster than the air and scatters at the ground surface.  Therefore, by checking the presence/absence of the helium gas by the helium leak detector 6, a leakage of the compressed air from the tunnel can be detected before the compressed air leaks to the ground surface.

Title: Ink jet recording paper, and ink jet recording method
Inventor: KASAHARA KENZO
IPC: D21H27/00
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To ensure a high water resistance and a high moisture resistance with a small consumption amount of a cationic mordant by making a pH value of a recording surface side film surface of an ink absorbing layer to be a specified value. SOLUTION: At least one layer of an ink absorbing layer containing a hydrophilic binder and a cationic mordant having a mordant force for an anionic dye, is provided on a supporting body, and the film surface pH on the recording surface side of the ink absorbing layer is made 3 or higher and 5 or lower. When the film surface pH is less than 3, the water resistance and the moisture resistance are improved, but when an ink jet recording is performed, a dye coagulates on the moment when a recording liquid comes into contact with the surface of a recording paper, or the dye is deposited on the surface by time passing after a recording, and a favorable maximum concentration cannot be obtained, and a color tone defect may be generated.  Also, when the film surface pH exceeds 5, the water resistance and the moisture resistance become insufficient, and especially the reduction of the moisture resistance is large. Therefore, the best water resistance and moisture resistance can be obtained by using a minimum necessity amount of the cationic mordant, and a defect due to the usage of a large amount of the cationic mordant can be prevented from arising.
