Abstract

This gas generator comprises: an ignitor; a gas-generating agent that generates combustion gas by combustion caused by activation of the ignitor; a housing in which the ignitor and the gas-generating agent are contained; a gas discharge hole penetrating through the housing; and a metal seal which is formed in sheet shape and is attached to the inner surface of the housing. Prior to activation of the ignitor, the metal seal covers the opening of the gas discharge hole on the inner surface side of the housing and thus closes the gas discharge hole. As the ignitor is activated, the metal seal is cleaved due to the pressure of the generated combustion gas, thereby opening the gas discharge hole. The gas discharge hole includes a chamfered region in which the corner of the opening on the inner surface side of the housing is removed along the circumference.

Abstract

An occupant protection device includes a first sensor configured to output vehicle information indicating a traveling state of a vehicle and a situation around the vehicle, a second sensor configured to output occupant information indicating a seating state of an occupant, a stimulus application unit that is to be worn by the occupant and is configured to apply a stimulus to the occupant, and a controller configured to control the stimulus application unit. The controller predicts an impact to be received by the vehicle, determines a stimulus application content by the stimulus application unit necessary for correcting a posture of the occupant to a posture prepared for the impact when the impact is predicted, and activates the stimulus application unit in accordance with the determined stimulus application content and thus corrects the posture of the occupant prior to a timing when the vehicle receives the impact.

Abstract

The present invention provides: an equol-containing food composition which is capable of preventing microbial contamination; and a production method therefor. Further, the present invention provides a production method for an equol-containing food composition in which produced equol is efficiently collected. The present invention provides a food composition obtained, for example, by a production method for a liquid food composition for obtaining a pH-adjusted liquid food composition comprising equol. The production method for a liquid food composition for obtaining a pH-adjusted liquid food composition comprises: (A) a step of utilizing at least one raw material for equol selected from the group consisting of daidzein glycoside, daidzein, and dihydrodaidzein to culture microbes which utilize the raw material for equol to produce equol; and (B) a step of adjusting the pH of a culture fluid including the equol obtained in said culture step by adding a pH adjuster thereto.

Abstract

The present disclosure addresses at least the following problem. Specifically, the present disclosure addresses the problem of providing a technology that makes it possible to obtain high physiological activity when a liquid pharmaceutical composition containing an in-vivo-functional substance that exhibits physiological activity in a subject to whom the composition is injected. This problem is solved by a liquid pharmaceutical composition that contains an in-vivo-functional substance, that demonstrates an osmotic pressure greater than 400 mOsmol/kg but no greater than 1,000 mOsmol/kg, and that is injected into a subject by an injector for injecting a liquid pharmaceutical composition into a subject without the use of an injection needle.

Abstract

An electric circuit breaker device includes an igniter, a rod-like projectile, and a conductor portion for forming a part of an electric circuit, and an insulating closed space. The conductor portion includes a first and second connection portions and a cut portion at an intermediate portion, and is disposed with a surface of the cut portion. The rod-like projectile has an end portion facing the cut portion. The insulating closed space has an opening portion facing the conductor portion, a closed end surface opposite to the opening portion in the housing axial direction, and four side surfaces between the opening portion and the closed end surface. A width (W1) of the opening portion of the insulating closed space and a width (L1) of the end portion of the rod-like projectile have a relationship of W1>L1 and W1−L1≥0.25 mm.
