Abstract: In a nozzle device a spray hole for spraying washing water and a pipe forming a first flow path that introduces the washing water to the spray hole is provided. Further, the spray hole is provided in a cover that surrounds the pipe. The cover is integrally formed of a cylindrical metal whose front end is closed. A space between an outer surface of the pipe and an inner peripheral surface of the cover member forming a second flow path that introduces the washing water to the spray hole. Further, the second flow path surrounds surface of the pipe in a circumferential direction of the cover member.

Abstract: A collapsible lens barrel is provided, including a mechanism capable of reliably inhibiting rotation of a rotational barrel even if any impact is applied thereto, for example, due to a fall with the barrel being extended. When the rotational barrel is pressed upon a fixed member due to impact in defiance of the biasing force of a wave spring, a first engagement portion provided at a camera body-side end of the rotational barrel engages with second engagement portions provided on a subject-side surface of the fixed member, which locks rotation of the rotational barrel, thereby making it possible to prevent gears from being damaged, for example.

Abstract: Since the inner diameter of a flow-contracting portion continuously decreases toward a cylindrical swirl chamber, the velocity of flow of washing water flowing in the flow-contracting portion continuously rises. Since the inner diameter of the flow-contracting portion continuously decreases toward a spray hole, the velocity of flow of the washing water flowing in the flow-contracting portion continuously rises. Washing water supplied to one of flow paths in a two-flow path pipe is supplied to a flow path merger through a one-flow path pipe. The washing water supplied to the other flow path in the two-flow path pipe is supplied to the flow path merger after passing through a space between the one-flow path pipe and a nozzle cover.

Abstract: A biodata interfacing device includes a service console, an attachment storage compartment defined in the service console for accommodating a variety of sensors used for collecting biodata, a lid mounted on the service console for opening and closing a top opening of the attachment storage compartment, and a display unit formed on an upper surface of the lid.

Abstract: A biodata interfacing device includes a service console (1), an attachment storage compartment (3) defined in the service console (1) for accommodating a variety of sensors (31, 32, 33) used for collecting biodata, a lid (11) mounted on the service console (1) for opening and closing a top opening of the attachment storage compartment (3), and a display unit (12) formed on an upper surface of the lid (11).
