A pump unit and a pump capable of detecting characteristics of a conveyance article and a method for detecting the characteristics of the conveyance article. A pump unit includes an outer cylinder; an inner cylinder disposed on an inner circumference side of the outer cylinder; and a pressure supply chamber provided between the inner cylinder and the outer cylinder, the pump unit being configured to convey a conveyance article in the inner cylinder by supplying a pressurizing medium into the pressure supply chamber and thereby causing the inner cylinder to expand inwardly in a radial direction, in which the pump unit further includes a conveyance article information acquiring device configured to acquire information on the conveyance article in the inner cylinder at a time when the inner cylinder is expanded.

A tube unit includes an inner tube that is elastically deformable and has a tubular shape, and a pressurized space forming portion that forms a pressurized space in contact with an outer peripheral surface of the inner tube between the inner tube and the pressurized space forming portion. The inner tube is operable between a minimum pressure state and a maximum pressure state. The inner tube has a cross-section having a non-circular shape perpendicular to an axial direction in the minimum pressure state. A transport apparatus includes the tube unit and a pressure controller.

Tube unit and transport apparatus

An input/output port, a birefringent element, variable polarization rotator, and a reflector are arranged along an optical axis in the order named. The variable polarization rotator includes permanent magnets for applying a fixed magnetic field to a Faraday rotator in an in-plane direction to magnetically saturate the Faraday rotator and a solenoid coil for applying a variable magnetic field to the Faraday rotator in a direction of the optical axis. A fixed magnetic field is applied in the &#x3c;211&#x3e; direction, in which the Faraday rotator is likely to be magnetically saturated. The Faraday rotator can be saturated with a low magnetic field of about 100 Oe. The permanent magnets may employ ferrite permanent magnets, which have weak magnetic forces. A variable magnetic field may also be reduced. Therefore, an air-core coil can be used.

Reflection type variable optical attenuator

An actuator is provided whose expansion in the radial direction can be efficiently translated into longitudinal movement when its length is contracted and extended by injecting a fluid into the tubular body. The fluid injection type actuator includes an actuator body, which is an expansion and contraction section of the actuator. The actuator body is constructed of a cylindrical rubber tube and annular fiber groups inserted and extending longitudinally therein. The annular fiber groups are each a group of fibers, such as glass roving fibers having a diameter of about 10 &#x3bc;m, arranged in an annular array along the circumference of the rubber tube. The arrangement allows the rubber tube to be restrained over the entirety of the actuator body longitudinally when it is expanded radially.
