Abstract: A laser tracking device includes an adjustment device, a telescope, and a drive device. The adjustment device modifies the emission direction of first light wave. The telescope emits the first light wave in the emission direction modified by the adjustment device. The drive device rotates the telescope based on a predicted path of a moving body. The adjustment device provides more precision in modifying the emission direction of the first light wave than in the drive device rotating the telescope. Further, the adjustment device modifies the emission direction to offset the modification of the emission direction caused by the rotation of the telescope from a time when a tracking start condition is satisfied until the moving body is detected.

Abstract: A chip that constitutes a pressure-sensitive sensor and an enclosure are provided. The enclosure is formed with a sensor placement chamber in which the chip is placed. In the sensor placement chamber in which the chip is housed, a first pipe connecting a first communication channel on the side of the sensor placement chamber to a first pressure introduction portion and a second pipe connecting a second communication channel on the side of the sensor placement chamber to the second pressure introduction portion are provided. A side surface of the first pipe and a side surface of the second pipe are disposed out of contact with an inner wall of the sensor placement chamber.

Abstract: A pressure switch includes an external force transmission mechanism for separating a cover from a housing. The cover and the external force transmission mechanism defines a first pressure chamber, and the housing and the external force transmission mechanism defines a second pressure chamber. In the second pressure chamber, a movable piece having first and second movable members arranged opposite to each other and one or more fixed contacts are disposed. The first and second movable members are connected to each other via a flat spring. A contact is disposed on the second movable member and functions as a movable contact. The external force transmission mechanism applies an external force to the first movable member to displace the first movable member, and the second movable member is reversed at the operating point of the first movable member, so that the movable contact is brought into contact with the fixed contact.

Abstract: A respiratory air flowmeter includes a flow path forming member, a restricting portion, rectifying lattices, and a sensor. The flow path forming member forms a flow path in which respiratory air flows. The restricting portion and the rectifying lattices are arranged in the flow path in order to stabilize a respiratory air flow. The sensor is mounted in a sensor mounting portion of the flow path forming member, and detects a flow rate of respiratory air flowing in the flow path.

Abstract: A velvet type tape for use as closing means or fasteners for garments, curtains and the like. The fastener tape comprises a woven foundation structure, and a number of material-engaging elements carried on one side of the foundation structure. Each of the material-engaging elements is in the form of a loop raised from the foundation structure, the loop including a head section remote from the foundation structure and a pair of outwardly diverging leg sections. Each of the leg sections has on its outer side at least one material-hooking groove for receiving a loop on a companion fastener tape. A method of producing such a velvet type fastener tape is also disclosed.

Abstract: A velvet type fabric tape for use as closing means or fasteners for garments, curtains and the like. The fastener tape comprises a woven foundation structure, and a number of material-engaging elements raised from one of opposite surfaces of the foundation structure. Each of the material-engaging elements is in the form of a mushroom-shaped loop having a pair of stalks juxtaposed on the foundation structure and an umbrella-shaped head borne on the stalks. The umbrella-shaped head includes a pair of material-hooking eaves each projecting from one of the stalks substantially parallel to the foundation structure for trapping loops on a companion fastener tape.

Abstract: A throat plate holding the feed dog of a twin-needle sewing machine has formed therein a pair of parallel spaced guide channels for slidably accommodating respective scoop-carrying edges of the pair of concealed fastener stringer tapes as they are stitched onto a fabric. When seen in a cross section, the guide channels diverge downwardly to prevent accidental disengagement of the scoop-carrying edges of the stringer tapes therefrom.
