Abstract:
The present invention provides the photocatalyst sheet and the methods of welding and manufacturing the same, by which the substrate and resin of the photocatalyst-containing layer are not decomposed by photocatalyst particles, mutual welding of sheets is easy, and the photo-redox effect of a photocatalyst can be obtained. A photocatalyst sheet (1b) comprises a substrate (2) such as fiber and coated layers (3) on both sides of the substrate (2), and the coated layer (3) constitutes the photocatalyst-containing layer in which apatite-coated photocatalyst particles (4) are dispersed and fixed with resin. Here, the coated photocatalyst particles (4) on the surface of the photocatalyst-containing layer are so fixed as to have the parts exposed from the surface of the photocatalyst-containing layer. In case that photocatalyst sheets (1b) are mutually welded, the photocatalyst-containing layer of each photocatalyst sheet (1b) is not removed, and its surface is mutually held, and welded together by thermal welding or others.
Abstract:
A sealable access stopcock includes a valve body having a switching part formed in a valve shaft thereof for switching from one flow passage to another; and a main body having an internal chamber in which the valve shaft of the valve body is rotatably fitted, and a plurality of tributary tubes each having a lumen extending therethrough, the lumen opening on a side wall of the internal chamber; the valve body being rotated to selectively bring the lumens into communication with one another through the switching part and thereby switch flow of an infusion fluid from one flow passage to another. A switching channel is provided in the form of an arcuate groove in the switching part of the valve shaft to extend along the circumferential surface thereof.
Abstract:
An internal part of an airbag is partitioned into a first chamber and a second chamber by first and second inner panels. Each of outer peripheral edge portions of the inner panels is stitched by a tear seam. Overhanging portions protrude from outer peripheries of each of the first and second inner panels, and each of the overhanging portions is stitched by a seam. The thickness of the airbag is relatively small by a continuum of the first inner panel and the second inner panel until the internal pressure of the first chamber reaches a predetermined pressure. At the predetermined pressure, the tear seam is broken, and each of the first and second inner panels is separated resulting in an increase in the thickness of the airbag. The airbag sufficiently absorbs the impact of the occupant, and does so in a relatively soft manner.
Abstract:
An airbag is formed by an airbag main body including a front panel disposed at a vehicle occupant side, and a rear panel disposed at a side opposite to the vehicle occupant side, combined at peripheral edge portions thereof. An inner panel partitions an interior of the airbag main body into a first chamber having an opening provided in the rear panel for facilitating inflation of the airbag, and a second chamber surrounding the first chamber. The inner panel is disposed such that a volume V1 of the first chamber is less than a volume V2 of the second chamber when the airbag main body is brought to completion of development by introduction of a fluid from an inflator. The device protects a vehicle occupant by expanding and developing both the first chamber and the second chamber in a well-balanced manner.
Abstract:
A vehicle occupant protection system includes a seat belt device and a knee bag device for protecting an occupant sitting on a seat of a vehicle. The protection system also includes a control unit for controlling the seat belt device and knee bag device based on a detection signal and a prediction signal from at least one of a device for detecting a state of the seat, a device for detecting whether the seat belt device is used, a device for predicting a collision, and a device for detecting a condition of an accident.
Abstract:
An airbag inflated by an inflator is formed of a front panel disposed at a position adjacent to an occupant, and a rear panel disposed at a position opposite to the occupant. Rims of the front panel and the rear panel are joined together. A joint member joins a center area of the front panel to the rear panel, so that a periphery of the airbag projects to the occupant more than the center area for a time of 10 to 60 msec after the airbag starts to inflate. With the airbag in a fully inflated condition, the periphery of the front panel projects toward the occupant by 10 to 100 mm more than the center.
Abstract:
An airbag apparatus includes an airbag that is defined by a plurality of chambers or by a plurality of small airbags. The airbag is configured in such a manner that not only the sequence of inflation of the respective chambers or airbags, but also the internal pressure upon inflation, is controlled independently. The airbag apparatus includes an inflator for inflating the airbag, a flow control member for allowing gas from the inflator to flow independently into the chambers or airbags, and a retainer. The inflator includes two gas generating units, which are configured to perform gas generating action independently. The flow control member is configured to allow gas from the first gas generating unit to flow into a first chamber or a first small airbag of the airbag, and gas from the second gas generating unit to flow into a second chamber or a second small airbag of the airbag.
Abstract:
An airbag includes an airbag body, and a support sheet attached to the airbag body. Each of the airbag body and the support sheet has a gas-generator insertion hole. The insertion holes' are disposed separately, wherein the support sheet faces the insertion hole of the airbag body and the airbag body faces the insertion hole of the support sheet. A space between the insertion holes of the airbag body and the support sheet serves as a gas-generator insertion space.
Abstract:
An occupant protecting device which makes it possible to inflate a bag of an inflatable seatbelt device or exerting a pre-tension upon a seatbelt by a gas generator for inflating a bag disposed at the front portion of a seat cushion. An occupant protecting device including an inflatable tube disposed under the front portion of a cushion pad. Gas from an inflator enters the tube through a cylinder. A piston is disposed inside the cylinder, and is connected to a lap anchor through a wire. A structure which causes a bag to be inflated by the gas from the inflator may also be used.
Abstract:
A leg protection device including an airbag arranged inside a member disposed in front of a seat. The device includes a gas generator for inflating the airbag; and a cover covering the airbag and configured to open when the airbag is inflated. The cover is configured to break along tear lines when the airbag is inflated to form a plurality of laterally arranged flaps when the airbag is inflated.
