Abstract: An open/closed display handle for rotating a spindle of an open/closed valve mechanism of a valve device includes a handle main body having a handle-side gear that rotates about an axis of the spindle, a rotary display body having an open/closed display portion that displays an open/closed valve state and a display body-side gear, and a rotary fixed body that pivotally supports planetary gears. The planetary gears, the handle-side gear, and the display body-side gear form a differential rotation mechanism, and a visual recognition restricting body that covers the rotary display body and has openings that open to allow a portion to be displayed of the open/closed display portion to be visually recognized from an outside and a transparent cover body that covers an entire outer side of the visual recognition restricting body and is translucent to allow visual recognition from an outer side form the handle main body.

Abstract: A one-way valve device or a non-return valve mechanism in the valve device provides a higher retaining residual pressure without upsizing. A non-return valve cassette in a consumption valve device regulates gas flow. The cassette includes a check valve movable forward and backward between a valve-closed position and a valve-open position in an outlet secondary flow channel and movable backward to the valve-open position under pressure of the gas flowing upstream, and a first coil spring with a spring force biasing the check valve upstream. The first coil spring permits the check valve to move downstream against the upstream biasing when an upstream pressure is a predetermined pressure or greater. The check valve includes a downstream end smaller than an upstream end in an area communicating with an upstream space at the valve-closed position.

Abstract: The flow path of a container valve communicates from a container attachment portion, to be attached to a fluid storage container, to an outlet, and is provided with a valve chamber, accommodating an open/close valve, in a middle part thereof. A portion of the flow path from an end of the container attachment portion to a bottom surface of the valve chamber is set as a primary flow path, and a portion of the flow path from an inner side surface of the valve chamber to an end of the outlet is set as a secondary flow path. In an outer circumferential portion of the bottom surface of the valve chamber, a discharge promotion groove is formed continuously with a portion corresponding to the lateral opening in a circumferential direction. A bottom surface of the secondary flow path is located below a bottom surface of the discharge promotion groove.

Abstract: A flow direction restriction valve mechanism unit includes a pressure decreasing valve assembly that is located to freely advance or retract in a combination valve cassette attached to an in-outlet secondary side flow path formed on the side of an outlet with respect to an intermediate transmission member in a flow path, and retracts by a pressure of gas; a first coil spring urging the pressure decreasing valve assembly in a retracting direction; a check valve that is located to be freely advance or retract with respect to the pressure decreasing valve assembly, and retracts by a pressure of the gas; and a second coil spring urging the check valve in an advancing direction. A gas induction passage is formed in which the gas flows and acts on the pressure decreasing valve assembly such that the pressure decreasing valve assembly moves in the advancing direction.

Abstract: An information output system in which an output destination management server is provided with an output destination management table for managing a mail address, performance information, and the like for each printer. In response to a search request from a terminal apparatus, the output destination management table is used to search for one or a plurality of candidate printers. The terminal apparatus is notified of the mail address of one candidate printer or the plurality of candidate printers. The terminal apparatus uses the mail address of a designated printer as a destination, and issues an electronic mail including the information to be printed. A printing mail server receives the electronic mail. The information included in the electronic mail is transferred to the designated printer from a print server. Accounting processing is executed prior to the printing of the information.

Abstract: A safety valve comprises a pressure receiving hole (20), an actuation chamber (21), a discharging hole (22) and an alloy accommodating chamber (25). An alloy (27) of a low-temperature melting point is accommodated within the alloy accommodating chamber (25). A sealing plate (33) seals the pressure receiving hole (20). This sealing plate (33) has a portion, which faces the pressure receiving hole (20), provided with a breakable sealing portion (35) that breaks up with a predetermined pressure. An actuator (28) is arranged within the actuation chamber (21). The actuator (28) has one end formed with a first back-up portion (30) which supports the breakable sealing portion (35) and has the other end formed with a second back-up portion (31) which is supported by the alloy (27).
