摘要:
A flexible and restorable container main body for housing a medicinal solution. A stopper member is fixed in an inside of a medicinal solution passage that communicates with the container main body for discharging the medicinal solution when the container main body is pressed and deformed. A pressure valve is arranged in the medicinal solution passage at a downstream side in the medicinal solution discharge direction further than the stopper member and is formed with an opening having a circular cross section which contacts a tip portion of the stopper member. A biasing member is provided at a downstream side for biasing the pressure valve in a direction opposite to the medicinal solution discharge direction by abutting against a peripheral portion of the opening of the pressure valve.

A liquid delivery container comprises a bag 2 which is disposed in a container body 1 to contain a liquid and can expand and shrink or deform freely, a delivery port 3 communicating with the bag 2 and having an outlet hole 31 for discharging the liquid contained in the bag 2, a squeeze portion 6 which is disposed between the delivery port 3 and the bag 2 and is capable of deforming to discharge the liquid through the delivery port when pressed and is restorable, and the check valve 5 disposed on the upstream of the squeeze portion 6 in the discharging direction and regulating the flow of the liquid contained in the bag 2 in one way toward the squeeze portion. When the squeeze portion 6 is pressed, the liquid is discharged through the delivery port 3, and when the pressure is removed, the squeeze portion 6 restores the original shape and at the same time sucks up the liquid from the bag 2.

A wavelength selective polarization controller capable of controlling the polarization plane of optical wavelength multiplexing signals, for each wavelength component, and which does not generate time lag between each component is provided. This wavelength selective polarization controller has: a telecentric optical system to which optical wavelength multiplexing signals are incident; a polarization controller that controls the polarization plane of light output from the telecentric optical system; and an output optical system for outputting to an optical path output from the polarization controller. The telecentric optical system has: a first diffraction grating to which the optical wavelength multiplexing signals are incident; and a first condenser that condenses the optical wavelength multiplexing signals that have passed through the diffraction grating. The polarization controller has a plurality of phase modulators.

An electrical connector to be connected to a flat conductive member includes a housing including an upper wall and a lower wall; a terminal including a contact portion for contacting with the flat conductive member; and an engaging protrusion for engaging the flat conductive member. The housing further includes a receptacle portion between the upper wall and the lower wall for receiving the flat conductive member. The upper wall includes a cut portion. The engaging protrusion is situated under the cut portion, so that an edge portion of the flat conductive member moves over the engaging protrusion and deforms into the cut portion when the flat conductive member is inserted into the receptacle portion.
