摘要:
A method for blowing a gas from below into a molten steel in a refining vessel, which comprises: using a refining vessel including at least one gas blowing aperture provided in the bottom wall thereof and a frustoconical plug matching with said aperture, releasably inserted into said gas blowing aperture, which has a small-diameter bore having a diameter within the range of from 0.5 to 6.0 mm and a length within the range of from 60 to 700 mm; closing the top end of said bore of said plug opening into said vessel with a granular packing easily removable by the pressure of a gas blown, thereby ensuring prevention of a molten steel received in said vessel from penetrating into said bore during receiving said molten steel into said vessel; after receiving a molten steel into said vessel, blowing from below a gas having a pressure of over the static pressure of said received molten steel through said bore of said plug into said molten steel, thereby removing said packing to effect a prescribed gas blowing into said molten steel; and, after discontinuing said gas blowing, causing a portion of said molten steel in said vessel to penetrate by gravity into said bore of said plug to solidify said molten steel in said bore, thereby closing said bore to ensure prevention of said molten steel in said vessel from flowing out from said vessel.

In the disclosed camera exposure control device, a first control automatically controls the camera exposure on the basis of a signal generated by a first brightness sensor. A second control automatically controls an exposure on the basis of a manual setting that responds to a second brightness sensor. A mode selector enables either an electromagnetic actuator that operates the first exposure control or a mechanical actuator that operates the second control.

A single lens reflex camera or a camera system uses a camera body unit and has a view finder unit permanently fixed to or detachably mounted on the camera body. A first terminal on the camera body is electrically connected with a synchronous device which is so arranged as to provide a synchronous signal related to the operation of a shutter device, while a second terminal which can contact with or can be coupled to the first terminal on said camera body when the view finder unit is attached to the camera body unit, is provided on the view finder unit. Therefore one or more electrical devices, which are built in the view finder unit or are detachably mounted on the view finder unit and require the synchronous signal related to the operation of the shutter device for having themselves activated, are electrically connected to the synchronous means through the contacting or coupling of the second terminal with the first terminal. A latch holds the view finder in position and aligns it with the camera body.

In a photographic camera for use with a single-reel magazine wherein the film after withdrawn by a film advancing sprocket for exposure purposes has to be transported backwards to the magazine while the sprocket being idle, a mechanism for releasing the sprocket from braking engagement with a drive member therefor is provided with two control or rewinding buttons arranged to be manually actuable from the outside of the camera housing at respective places, one of which is located in a recess of the bottom panel thereof so that, for example, when a motor drive unit is attached thereto, an automatic responding relationship is established therebetween, and another place which is located so that, while the user is unabled to make use of the first-named rewinding button, as, for example, a tripod remains left in attachment with the camera at its bottom panel, it is made possible to switch the camera from the film winding to the rewinding state.

An electrically operated extrinsic coordinating system for the light metering and exposure controlling circuits of a photographic camera, the camera also having incorporated therein an intrinsic coordinating system for those circuits, comprises first and second electronic switches connected in the respective power supply circuits for the light metering and exposure controlling circuits through respective interconnection channels to shunt the first and second switches of the intrinsic coordinating system, a delay circuit connected between the first and second electronic switches, and an operating switch arranged to be accessible from the outside of the camera and cooperative with the first electronic switch upon manual closure of the operating switch to actuate the light metering and exposure controlling circuits for the power supply in predetermined time-displaced relation to each other independently of the intrinsic coordinating system.
摘要:
A porous polyimide film having a three-layer structure that comprises two surface layers (a) and (b) and a macrovoid layer sandwiched between the surfaces layers (a) and (b). The macrovoid layer has a partition wall bonding to the surface layers (a) and (b), and multiple macrovoids each surrounded by the partition wall and the surface layers (a) and (b) and having a mean pore size in the film plane direction of from 10 to 500 μm. The partition wall of the macrovoid layer has a thickness of from 0.1 to 50 μm and has multiple pores having a mean pore size of from 0.01 to 50 μm. The surface layers (a) and (b) each have a thickness of from 0.1 to 50 μm, at least one of the surface layers has multiple pores having a mean pore size of from more than 5 μm to 200 μm, and the other surface layer has multiple pores having a mean pore size of from 0.01 to 200 μm. The pores in the partition wall of the macrovoid layer as well as in the surface layers (a) and (b) communicate with each other and further communicate with the macrovoids. The film has a total thickness of from 5 to 500 μm and a porosity of from 60 to 95%.

摘要:
A vehicle includes a front grille and a vehicle presence notification apparatus that includes a supersonic speaker, where the vehicle presence notification apparatus is behind the front grille. The front grille includes a plurality of grille bars that may be in a front range of the supersonic speakers. The grille bars that are positioned in the front range of the supersonic speaker includes a curved convex and an upper plate, which have a substantial U shape cross section. The supersonic wave is reflected on an inside surface of one grille bar in a downward direction, and is reflected again on an outside surface of an adjacent grille bar in a forward or frontal direction to output toward a front field of the vehicle.

A sheet processing apparatus includes a feeding portion that feeds an original or a recording medium, a reading portion that reads an original, and a recording portion that performs recording on a recording medium. The original or recording medium fed from the feeding portion can be selectively conveyed to the reading portion or the recording portion, thereby allowing for compactness of the apparatus as well as cost reduction.
