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.

Provided are a flexible and restorable container main body (1) for housing a medicinal solution; a stopper member (4d; 14d) fixed in the inside of a medicinal solution passage (P) communicated with the container main body (1) for discharging the medicinal solution when the container main body (1) is pressed and deformed; a pressure valve (5) arranged in the medicinal solution passage (P) at a downstream side in the medicinal solution discharge direction further than the stopper member (4d; 14d) being formed with an opening having a circular cross section which contacts the tip portion (4e; 14e) of the stopper member (4d; 14d); and a biasing member (7; 7a) at a downstream side for biasing the pressure valve (5) in a direction opposite to the medicinal solution discharge direction by abutting against a peripheral portion (5b) of the opening of the pressure valve (5).
摘要:
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.

摘要:
An electronic grade synthetic quartz glass substrate is manufactured by machining a synthetic quartz glass substrate to form a recess, channel or step and polishing the bottom and side surfaces of the recess, channel or step to mirror finish by a working portion of a rotary polishing tool while keeping the working portion in contact with the bottom and side surfaces under independent constant pressures.

Provided is a wavelength variable laser device wherein an SOA is simplified. The wavelength variable laser device includes: an optical filter formed on a PLC; an SOA that supplies light to the optical filter; a light reflecting section that returns the light transmitted through the optical filter to the SOA via the optical filter; optical waveguides which are formed on the PLC and connect the SOA, the optical filter, and the light reflecting section; a wavelength variable section that changes a wavelength of the light transmitting through the optical filter; and a phase variable section that changes a phase of the light propagated on the optical waveguides.
摘要:
An image forming apparatus, which appropriately performs a banding correction even if similar banding does not always occur at a same position of a recording medium, detects reflected light from a test patch image and obtains information on a density change caused by a periodically-uneven rotation of a rotation member, and performs a density correction at an arbitrary position of a print image based on the acquired information on the density change.
摘要:
A thermoplastic resin foam which has both high reflectance and superior shape-retention properties, suitable for use in backlights and illumination boxes for illumination signboards, lighting fixtures, displays and the like. The thermoplastic resin foam is manufactured by a manufacturing method including a procedure for holding a resin sheet composed of thermoplastic resin (A) and thermoplastic resin (B), which has a functional group having an affinity with thermoplastic resin (A), within a pressurized inert gas atmosphere to enable the resin sheet to contain inert gas, and a procedure for foaming by heating the resin sheet containing inert gas at a temperature higher than the softening temperature of thermoplastic resin, under normal pressure.
摘要:
A wavelength variable laser includes: a substrate on which an optical coupler is formed as a planar optical waveguide; a DFB array part arranged on the substrate and having DFB laser elements respectively supply optical signals to the optical coupler; and an SOA part arranged on the substrate and having an SOA element configured to amplify an optical signal outputted from the optical coupler. The DFB array part and the SOA part are respectively formed in chips having a same lamination structure to each other. A wavelength variable laser and a modulator integrated wavelength variable laser with high yield ratio can be provided.
