A throttle valve device includes a body, a valve, a motor, and a cover. The body defines a passage, a motor space, and a connecting portion that connects the motor space to the passage. The motor includes a motor yoke made of a magnetic material, a plurality of magnets that are arranged on an inner circumferential surface of the motor yoke. The plurality of magnets are magnetized in a state where the motor yoke is disposed in the motor space of the body. The plurality of magnets are arranged in a circumferential direction in the motor yoke with a space. The connecting portion is aligned with the space between the plurality of magnets in a radial direction of the motor yoke.

A valve device is provided with a valve body driving member rotated by driving force from a drive source, and a valve body rotating in a circumferential direction integrally with the valve body driving member. Fitting parts fitted one another are formed in the lower surface of the valve body driving member and the upper surface of the valve body. The valve body has hole parts formed therethrough in the axial direction thereof. Groove parts that are flow channels linking from the outer peripheral surface of the valve body to the hole parts are formed in the upper surface of the valve body. The fitting parts and the groove parts on the valve body side have connecting parts that are portions where the fitting parts and the groove parts are formed continuously in the upper surface of the valve body without being separated by other elements constituting the valve body.

A toilet bowl system for use on-board an aircraft includes a toilet bowl body comprising a toilet bowl and a shroud. The toilet bowl has a rim. A removable splash guard is positioned between the toilet bowl and the shroud, and comprises a generally flat, flexible, planar shield having a central opening. The shield includes a top portion and a rear portion, the top portion faces the shroud and the lower portion faces the toilet bowl, and the lower portion is shaped to correspond with an upper portion of the rim of the toilet bowl and is configured to secure the removable toilet splash guard to the toilet bowl.

A heat exchanger which exchanges heat with a DUT while contacting the DUT includes: a heat exchange block which thermally contacts the DUT; a first heat transfer sheet which overlaps a front end surface of the heat exchange block; a second heat transfer sheet which overlaps the front end surface of the heat exchange block through the first heat transfer sheet; and a first holding member which holds the second heat transfer sheet.

The present invention relates generally to a blind valve. More particularly, the present invention relates to a line blind valve capable of: minimizing provision of gaskets for maintaining airtightness, thus making it possible to use of a gasket suitable for high temperature and cryogenic fluid and enable easy replacement thereof; eliminating provision of unnecessary components, thus simplifying an assembly structure of the valve so as to be easily disassembled and assembled; and being robust through structural characteristics of a system block, thus reducing the amount of deformation of a valve body unit and improving structural stability and durability.

Disclosed is a vacuum valve having a valve seat, which has a valve opening, defining an opening axis, and a first sealing surface, a valve closure having a second sealing surface corresponding to the first sealing surface, a drive unit coupled to the valve closure, which can be moved from an open position, in which the valve closure and the valve seat do not contact each other, to a closed position, in which there is a sealing contact between the first sealing surface and the second sealing surface by a seal there between, and the valve opening is sealed gastight as a result. The vacuum valve has at least one temperature sensor, where the temperature sensor is designed and arranged such that, from the temperature sensor, a measurement signal representing thermal information in respect of at least one part of the vacuum valve can be detected.

A target opening degree estimator estimates a target opening degree estimation value as an opening degree of a valve element of a pressure adjustment vacuum valve when a pressure of a vacuum chamber connected to the pressure adjustment vacuum valve reaches a pressure adjustment target pressure based on a correlation between the opening degree of the valve element and the pressure of the vacuum chamber, a current opening degree, and a current pressure.
