摘要： A high-sensitive and high-accuracy vibrating type pressure sensor 1 allowing a corrosive gas pressure to be directly applied thereto, having a heat resistance, and having no room for mixing of noise into a vibrator, comprising a stainless steel pressure receiving diaphragm 4 for receiving a fluid pressure P on a rear surface side, the vibrator 12 formed on the front surface side of the pressure receiving diaphragm 4, a wall body 8 disposed so as to surround the periphery of the vibrator 12, and a permeable part 20 for light transmission for changing an internal space in which the vibrator 12 is present into a vacuum chamber 10 by closing an opening part 8a in the wall body 8, whereby, since the diaphragm 4 is formed of the stainless steel with corrosion resistance, the sensor can also be applied to corrosive fluid, since circuit wiring is eliminated from the vibrator 12 and the vibrator is isolatedly disposed in the vacuum chamber 10, mixing of electromagnetic noise can be eliminated, and since the resonance frequency fn of the vibrator 12 is performed by optical measurement in the state of non-contact, extremely high-sensitive and high-accuracy detection can be performed. A forced vibration means 57 can also be operated by piezo driving and electrostatic driving from the outside without generating noise.

摘要： An active slender tube as implemented as a catheter, guide wire, or any other medical or non-medical micro-mechanical or -system or system's active micro-component is disclosed that has a simple structure which facilitates the active slender tube to be reduced in diameter and with the capability of being multi-functionalized. The slender tube is provided in its distal, active end portion in the form of "J" with a bending, a torsionally rotating, an extending and retracting and/or a stiffness control mechanism. These mechanisms are adapted to bend, torsionally rotate, extend/retract and adjust stiffness of, the active end portion, respectively, with precision. Each mechanism comprises an outer skeleton including a liner coil spring, and an SMA (shape memory alloy) made coil actuator disposed inside of the liner coil coaxially therewith and fastened thereto. In the extending and retracting mechanism, the SMA made actuator is fastened to the liner coil spring upon deformation to have a length varied from a length of the SMA made actuator in its natural state. In the torsionally rotating mechanism, the SMA made actuator is fastened to the liner coil spring upon deformation to have a coil diameter torsionally varied from a coil diameter of the SMA made actuator in its natural shape memory step. The stiffness control mechanism has an SMA made actuator in its natural shape memory state.
