A nuclear reactor vibration surveillance system has a first ultrasonic transducer for transmission, an ultrasonic transmitter, a second ultrasonic transducer for reception, an ultrasonic receiver, a signal processor, and a display unit. The first ultrasonic transducer for transmission is arranged on the outer surface of a reactor pressure vessel and is configured to convert a transmission signal into an ultrasonic pulse signal and allow the ultrasonic pulse to be transmitted to a reactor internal component. The second ultrasonic transducer for reception is arranged on the outer surface of the reactor pressure vessel and is configured to receive a reflected ultrasonic pulse reflected by the reactor internal component and convert the received reflected ultrasonic pulse into a reception signal.

A simple technique for introducing a hybrid alignment or a homeotropic (vertical) alignment into liquid crystal films, which, by their nature, tend to have a horizontal alignment of liquid crystal molecules. The technique does not require special alignment films. A liquid crystal composition for forming a liquid crystal film contains a polymerizable liquid crystal compound and a hydrolysate of an alkoxysilane compound. The hydrolysate of the alkoxysilane compound contains a siloxane oligomer of which degree of polymerization is from 2 to 25. Furthermore, the alkoxysilane compound is a trialkoxysilane compound having a functional group. This liquid crystal film composition can be produced by hydrolyzing an alkoxysilane compound to obtain a hydrolysate and then uniformly mixing the hydrolysate with a polymerizable liquid crystal compound. Alternatively, it can be obtained by uniformly mixing the alkoxysilane compound with the polymerizable liquid crystal compound and subsequently hydrolyzing the alkoxysilane compound in the mixture. One mole of the alkoxysilane compound is preferably hydrolyzed with 0.1d to 2.0d mol of water, given that the number of alkoxyl groups in a molecule of the alkoxysilane compound is d. An optically anisotropic film can be obtained by applying the liquid crystal film composition to a base film, causing the liquid crystal molecules in the composition to align in a nematic alignment, and curing the composition. The alignment of the liquid crystal molecules in the film is preferably a nematic hybrid or nematic homeotropic (vertical) alignment.

The present invention provides a removing method of a tube. Upon removing a tube 3 increased in diameter and fixed to a tube-sheet 1, an inserted portion 3a which is fixed to a tube-hole 2 of the tube-sheet 1 is heated and then cooled, thereby reducing its diameter. The inserted portion 3a is loosened from the tube-hole 2. Then, a region 3h opposed to a groove 4 formed in an inner circumference of the tube-hole is heated to a red-hot state, and the tube 3 is stretched in its axial direction, the red-heated region 3h is stretched to reduce its diameter and cut the region 3h, thereby pulling out the tube 3 from the tube-sheet 1.

When a user accesses an IC card system, the user intentionally registers processing or actions necessary for an IC card to an IC card management system, or the system determines a predetermined state to register the processing to the IC card management system. The IC card management system beforehand delivers the actions to an IC card terminal. Thereafter, when the user inserts the IC card of which the necessary actions have been registered to the IC card management system to the IC card terminal, the IC card terminal executes the actions corresponding to the IC card.

A Mo-W material for the formation of wirings is discloses which, as viewed integrally, comprises 20 to 95% of tungsten and the balance of molybdenum and inevitable impurities by atomic percentage. The Mo-W material for wirings is a product obtained by compounding and integrating a Mo material and a W material as by the powder metallurgy technique or the smelting technique or a product obtained by arranging these materials in amounts calculated to account for the percentage composition mentioned above. The Mo-W material containing W in a proportion in the range of from 20 to 95% manifests low resistance and, at the same time, excels in workability and tolerance for etchants. The wiring thin film which is formed of the Mo-W alloy of this percentage composition is used as address wirings and others for liquid crystal display devices. The Mo-W target for the formation of wirings is composed of 20 to 95% of tungsten and the balance of molybdenum and inevitable impurities by atomic percentage and allows the Mo-W wiring thin film to be produced with high repeatability.

An endoscope system includes a movement detector for detecting an operator's movement, a signal processor for processing a signal the detector detects, and a control for controlling drive which drives a medical device according to an output signal of the signal processor. The endoscope system bends a bending section of an endoscope serving as a medical device according to the operator's movement, and thus orients the observation field of view to a direction the operator intends or controls the movement of a treatment adapter serving as a medical device. The endoscope system includes a superimposing means for superimposing an image associated with the operator's movement onto an image acquired by an imaging device associated with the endoscope system.
