    摘要: A needleless injector configured to inject an injection intended substance to an injection target region, by injecting the injection intended substance includes a nozzle portion and a pressing portion, and a predetermined gap is formed between the nozzle portion and the pressing portion. The nozzle portion is formed to have a portion of the distal end portion that comes into contact with the injection target region and has a width (a) falling within a range from 3.5 mm to 5.5 mm, and a ratio (b/a) defined by an inner diameter (b) of a portion of a distal end portion of the pressing portion that comes into contact with the injection target region by the width (a) falls within a range from 1.5 to 5.0. A part of the injection target region is received in the predetermined gap when the pressing portion presses the injection target region.

    摘要: Proposed is a measurement system for measuring a behavior of an ejection liquid, which is ejected into an object from an ejection device, within the object. The system includes a container part formed of a resin material. The system also includes an imaging device disposed to image, across the object, a tip surface of the container part having an ejection port formed therein and being in contact with the object from a back side of the object in a predetermined state in which the ejection port is positioned from a front side of the object. The system further includes a first emission device that emits first near infrared light to the tip surface. In such a configuration, the behavior of the ejection liquid when the ejection liquid is ejected into the object from the ejection device can be imaged and measured by the imaging device.

    摘要: An ignition device assembly includes an ignition device including an igniter body and an igniter collar member, and a housing including a tubular fixing portion to which the igniter collar member is fixed. The tubular fixing portion includes a crimping fixing portion. The igniter collar member includes a tubular wall portion having a tubular shape, made of metal, and including a connector connection space formed inside, the tubular wall portion being crimped by a crimping fixing portion, an opening end forming portion including a resin region portion and a metal region portion, extending from a tip side of the tubular wall portion and forming an opening end of the connector connection space, and a crimping tip surface opposing region portion. At least a part of the crimping tip surface opposing region portion is formed by the metal region portion.

    摘要: An igniter assembly includes: an igniter including a container made of metal and an ignition charge, the igniter being configured to emit a combustion product of the ignition charge to an outside of the container when a lid wall portion is ruptured when the igniter is operated, the container including a peripheral wall portion having a tubular shape and the lid wall portion configured to close one end portion of the peripheral wall portion, the ignition charge being filled in an accommodating space defined by the peripheral wall portion and the lid wall portion; and a tubular wall portion made of resin and formed in a tubular shape in a manner that the peripheral wall portion is surrounded, the tubular wall portion inwardly forming an emitting space in which the combustion product of the ignition charge is emitted. The lid wall portion includes an annular outer peripheral region portion connected to one end portion of the peripheral wall portion and a central region portion positioned inside the outer peripheral region portion in a radial direction compared to the outer peripheral region portion, and the outer peripheral region portion is formed thicker than the central region portion.

    摘要: A filter unit for a gas generator includes a filter and a filter housing coaxially positioning and fixing the filter in a filter accommodating space. The filter housing includes a first restraining end part disposed as a closing surface at one end of the filter housing and restraining a one axial end surface of the filter, a second restraining end part disposed at an other end of the filter housing, surrounding a gas inflow port, and restraining an other axial end surface of the filter, and a peripheral wall part connecting the first restraining end part and the second restraining end part and including a gas discharge port. The peripheral wall part includes a restraining peripheral wall part restraining a peripheral surface of the filter, and a non-restraining peripheral wall part in which the gas discharge port is disposed.
