Abstract:
In the simulator for shooting down the rapids in accordance with the present invention, a platform is installed on one side of a water channel in which a boat moves, and a theater zone is installed on the other side. In the theater zone, a boat swaying device and a wind generating device are installed, and these devices are successively operated in synchronization with the picture projected on a screen in the theater zone by a projector. Also, according to the present invention, three spherical seats are arranged in an isosceles triangle form under the boat moving in the water channel, and three vertically movable swaying rods are installed under the water channel in the theater zone at the positions corresponding to the spherical seats.
Abstract:
A sound-absorption material for an automobile includes a damping material, a sound-absorption material and a surface material. The damping, sound-absorption and surface materials are integrated together. The damping material includes a moldable plastic constraining material and an adhesive damping sheet containing a petroleum resin. The sound-proof material is integrally attachable to an automotive sheet material such as a dashboard.
Abstract:
A roof lining structure in a motor vehicle includes a roof lining base member and a vibration-damping layer interposed between an upper surface of the base member and a lower surface of a roof panel of the motor vehicle. The roof lining base member comprises a support layer having a cellular structure, and a reinforcing layer disposed at least partly in the roof lining base member. The upper surface of the vibration-damping layer is held in intimate contact with the lower surface of the roof panel. The vibration-damping layer is bonded to the roof panel by an adhesive layer. The vibration-damping layer is made of a material having such a mechanical strength that the vibration-damping layer will be torn apart vertically with a tearing force weaker than the bonding strength of the adhesive layer.
Abstract:
In a magneto-optical recording element comprising a substrate, a magnetic layer and a dielectric layer, the dielectric layer is formed by deposition of a composition comprising Si.sub.3 N.sub.4 and a refractive index-improving agent such as Al.sub.2 O.sub.3 or Y.sub.2 O.sub.3. This dielectric layer has a high refractive index and the enhancement effect is improved. Moreover, this dielectric layer is excellent in the adhesion and resistance characteristics.
Abstract:
A positioning apparatus for positioning an arm of an industrial robot comprises a frame member connected to the robot arm and being movably supported by a frame-supporting member. The frame-supporting member is movably mounted within an upstanding hollow sleeve of a stationary base, and a bearing is formed between an outer peripheral surface portion of the frame-supporting member and an inner peripheral surface portion of the base hollow sleeve portion for slidably mounting the frame-supporting member to undergo linear and angular sliding movements relative to the base hollow sleeve portion. A rotary motor effects angular driving movement of the frame-supporting member, and a linear motor effects linear movement of the frame-supporting member to thereby accurately position the robot arm. By such a construction, the frame-supporting member is mounted for angular and linear sliding movements relative to the base hollow sleeve portion by a single bearing.
Abstract:
An apparatus for continuously stretching dough for cakes, bread and the like, comprising a plurality of rollers progressing along a closed orbit comprising a lower straight portion, a plurality of conveyor belts positioned thereunder, with the upper flights of said conveyor belts being spaced apart from each other.
Abstract:
A copper alloy consisting of two or more of Cr, Ti and Zr, and the balance Cu and impurities, in which the relationship between the total number N and the diameter X satisfies the following formula (1). Ag, P, Mg or the like may be included instead of a part of Cu. This copper alloy is obtained by cooling a bloom, a slab, a billet, or a ingot in at least in a temperature range from the bloom, the slab, the billet, or the ingot temperature just after casting to 450° C., at a cooling rate of 0.5° C./s or more. After the cooling, working in a temperature range of 600° C. or lower and further heat treatment of holding for 30 seconds or more in a temperature range of 150 to 750° C. are desirably performed. The working and the heat treatment are most desirably performed for a plurality of times. log N≤0.4742+17.629×exp(−0.1133×X) (1)
Abstract:
A sheet conveying device includes: a conveying unit; a nonvolatile memory; and a controller. The conveying unit is configured to convey a sheet along a conveying path. The controller is configured to control the conveying unit to convey the sheet, store position data in the nonvolatile memory during conveyance of the sheet, determine whether or not the sheet conveying device is started, and drive the conveying unit for an amount determined by the position data if the sheet conveying device is started. The conveying path is divided into a plurality of segments. The position data identifies a segment in which the sheet stays. The more downstream the segment identified by the position data is in the conveying path, the smaller the amount determined by the position data is.
Abstract:
Disclosed are a Ti alloy having an excellent hydrogen absorption inhibition effect, a Ti alloy member using the Ti alloy, and a manufacturing thereof. A Ti alloy is characterized in that it contains 0.1 to 5.0% by mass in total of at least one of Zr and Hf, and a residue comprising Ti and impurities.
Abstract:
In an image reading apparatus, it is judged whether an original sheet is a first sheet type, whose sheet length is longer than or equal to a first conveyance distance and shorter than a second conveyance distance, and a second sheet type, whose sheet length is longer than or equal to the second conveyance path, the first conveyance distance being a distance between a first conveyance roller and a second conveyance roller, the second conveyance distance being a distance between a supply roller and the second conveyance roller. At least one of a leading-edge arriving timing; a trailing-edge arriving timing; and a sub-scanning magnification is set dependently on the judged result. An image is read from the original sheet by using an image reading unit and a conveyance unit based on the set at least one of the leading-edge arriving timing; trailing-edge arriving timing; and sub-scanning magnification.
