Abstract: Provided is an information processing device, and an information processing method for curbing occurrence of a feeling of strangeness in augmented reality in a use environment for a plurality of people. Position information indicating the self position of an AR device that outputs an AR object that is shown to the user as if the AR object existed in real space is acquired by the AR technology, and a deviation weight which is an evaluation value indicating how easily a plurality of users recognizes that an arrangement position of the AR object is deviated from each other on the basis of position information of a plurality of the AR devices and the arrangement position of the AR object. Then, the output method of the AR object is adjusted according to the deviation weight to make it difficult to recognize occurrence of the deviation.

Abstract: An externally threaded portion 31 of a valve body 10 is threadingly engaged with an internally threaded portion Hb formed on the opening portion side of an attachment hole Ha. A flange portion 32 of the valve body 10 is brought into abutment with an upper surface Hc of the housing H, so that the valve body 10 is fixed to the housing H. A lower end of the valve body 10 is located away from a bottom surface of the attachment hole Ha. A valve seat 23 and a guide hole 24 are formed inside the valve body 10. The valve seat 23 and the guide hole 24 are located on a lower side than the externally threaded portion 31. A valve element 50 is provided inside the valve body 10. This valve element 50 includes a seat portion 51 rest on the valve seat 23, and a guide portion 55 slidably engageable with the guide hole 24. A lower end opening portion of the guide hole 24 is shielded with a shielding plate 25. An orifice 25a is formed in the shielding plate 25.

Abstract: A pump for low-viscosity fuel comprises a pump shaft 6 installed in a pump housing 2, 3, 4 and divided into a drive-side shaft 6A and a driven-side shaft 6B, a partition 12 provided between the drive-side shaft and the driven-side shaft of the pump shaft to prevent leakage of fuel from the housing, and a magnetic coupling 13 for transferring torque from the drive-side shaft to the driven-side shaft of the pump shaft through the partition, the magnetic coupling being disposed such that a first clearance C1, D1 between the magnetic coupling and the partition is larger than a second clearance C2, D2 between the magnetic coupling and the pump housing. When wobble occurs in the pump shaft owing to wear of the sliding contact portions thereof, the magnetic coupling makes contact with the pump housing before contacting the partition, thereby enabling the rotation of the pump shaft to be stopped before fuel leakage occurs.

Abstract: A radial piston pump for low-viscosity fuel according to a first aspect of the invention comprises a pump housing, which is constituted of as few as two structural bodies (from among a drive-side housing member 2A, a fixed cylinder 81 and a cover 4), and a leaf valve member 82 which is formed with intake valves 87 for opening and closing intake side passages 27 and discharge valves 88 for opening and closing discharge side passages 28 and is sandwiched between two structural bodies (fixed cylinder 81 and cover 4). The first aspect of the invention reduces the number of components constituting the pump housing, enables highly precise overall axial alignment, prevents wobbling of a pump shaft 9 of the pump, increases performance and reliability and reduces cost.

Abstract: This invention rapidly and surely joins sheet bars to each other for continuously hot rolling in a high productivity by a combination of a treatment that the front end portion and the back end portion of these sheet bars are contacted and heated at such a contact region by applying alternating magnetic fields so as to pass in a thickness direction of the sheet bar with a treatment of pushing at least one of these sheet bars.

Abstract: In this invention, a back end portion of a preceding sheet bar and a front end of a succeeding sheet bar are cut in a transfer line at an entrance side of a finish rolling mill so that at least both side edge regions of these sheet bars are contacted with each other at a butted contact state thereof and a gap is formed between both end portions and then portions to be joined int he preceding and succeeding sheet bars are locally heated and pushed to join them while gradually enlarging a joining area, whereby the required time is largely reduced as compared with the conventional technique and also it is attempted to miniaturize the heating apparatus and shorten the length of the apparatus.

Abstract: In the continuously hot rolling of plural sheet bars, in order to simply and surely join the sheet bars to the back end portion of the preceding sheet bar and the front end portion of the succeeding sheet bar are prejoined by butting to each other at an entrance side of a finish rolling mill and then bitten into the finish rolling mill, during which the joining of the sheet bars are promoted to conduct the continuous rolling.

Abstract: A method of continuously hot-rolling sheet bars in which a roughly rolled leading sheet bar and a trailing sheet bar are abutted prior to a hot finish rolling step. Plastic deformation of either or both of the cut rear and front end portions of the leading and trailing sheet bars is applied. End portions are brought into contact with each other due to metal flow, forming a gap portion between the sheet bars. The thickness of the sheet bar around the gap portion is enlarged in comparison to the thickness of the contact portions, and hot finish rolling fills the gap so that the bars are strongly joined over their width.

Abstract: A fuel injection device for a diesel engine or the like confines the fuel injection pressure to a predetermined range. Fuel is fed under pressure from a fuel supply source to a high pressure chamber to develop a pressure therein. An injection nozzle is mounted on a nozzle holder and has a nozzle hole for injection fuel in response to the pressure in the high pressure chamber. The nozzle holder has thereinside a low pressure chamber which communicates to the outside. An injection rate control valve is mounted in the nozzle holder for delivering fuel to the low pressure chamber on the elevation of the fuel pressure communicated to the high pressure chamber beyond a predetermined value.

Abstract: Three way valves forming a fuel cut-off valve are arranged across respective injection pipes connected to injection nozzles associated with preselected cylinders of the engine. In a first valve position, the three way valves connect the injection pump body or bodies of the fuel injection pump to the respective injection pipes, and in a second valve position, they connect the injection pump body or bodies to a lower pressure zone in the pump. Preferably, the fuel cut-off valve is pneumatically operated for high speed valve position changing action.
