Abstract: A head mounted display device comprises a frame, an image display unit, an extension member and a retaining mechanism. The frame includes a front part, a connection part and a temple part. The front part is mountable on a user's nose and extends in a right-and-left direction in front of the user's eye. The connection part is fixed to at least one edge portion of right and left side edges of the front part and extends in a rearward direction from the one edge portion. The temple part is mountable on the user's ear and rotatably connected with the connection part around a rotation axis extending along an up-and-down direction. The image display unit includes an optical system and is configured to generate an image to be displayed for the user. The extension member extends in a forward direction from the one edge portion. The retaining mechanism is configured to detachably retain the image display unit in the extension member.

Abstract: A head mounted display includes: a projection part which projects an image corresponding to image information onto a retina of an eye of a user; and an eyeglasses-type frame which supports the projection part. The eyeglasses-type frame includes a resilient bent portion having a Z shape in a plan view on middle portions of left and right temples thereof. The projection part is arranged in front of the resilient bent portion of the eyeglasses-type frame.

Abstract: An electric-power-generating-facility operation management support system includes an analyzing unit that calculates operation plan creating basic information based upon received information with regard to lifespan calculating expressions, present electric-power market information, and operation-history information with regard to electric power generation, and an operation plan creating unit that calculates and outputs operational conditions of electric power generating facilities as created operation planning based upon said operation plan creating basic information calculated by said analyzing unit. The analyzing unit includes a lifespan-consumption-costs calculating unit that calculates lifespan consumption costs of said electric power generating facilities, a reserve-electric-power-price estimating unit that estimates the market price of reserve electric power, and a reserve-electric-power supply-probability estimating unit that estimates probability of supply of reserve electric power.

Abstract: A lens array element has a rectangular plate-like external shape, and includes plate surfaces that functions as light transmission surfaces; and a plurality of cellular lenses that are formed on at least one of the plate surfaces. Each of end faces 4 of the rectangular plate-like external shape forms an inclined surface that slants inward from a plate surface 6 on one side toward a plate surface 2 on the other side, and a reference surface 5 perpendicular to the plate surface is formed on a part of at least two adjoining end faces among the end faces. A front view shape of the reference surface region arranged side-by-side with the inclined surface of the end face is a trapezoid, an oblique side 7 of the trapezoid is disposed so as to extend from a plate surface on one side toward the plate surface 2 on the other side, and an upper side 9 of the trapezoid is disposed on a side of the other of the plate surfaces.

Abstract: A head mounted display device has a frame. The frame includes a front portion mountable on a nose of a user, and extending to a right side edge of the front portion, and to a left side edge of the front portion, in front of at least one eye of the user, a connection portion connected to an edge portion of at least one of the right and left side edge, and the connection portion extends rearward from the edge portion, and a temple portion configured to be mountable on an ear of the user, rotatably connected to the connection portion, and rotates around a rotation axis. The head mounted display also has an image display unit having an optical system, for generating an image to be displayed at a position viewable by the user, and a retaining mechanism to hold the image display unit within the connection portion.

Abstract: The present invention provides a turbine system which can start a turbine, while controlling thermal stress generated in a turbine rotor and an expansion difference, due to thermal expansion, between a casing and the turbine rotor, to be lower than defined values, respectively. The turbine system (1) according to the present invention includes the turbine (4) having a casing (2) and the turbine rotor (3) rotatably attached to the casing (2), and a main steam pipe (5) connected to an upstream portion of the casing (2). A control valve (6) adapted for controlling a flow rate of steam discharging into the casing (2) is provided with the main steam pipe (5), and a power generator (7) is coupled with the turbine rotor (3). Additionally, a starting control system (10) is adapted for controlling the control valve (6), while obtaining an operational amount of the control valve (6).

Abstract: A lens position adjusting mechanism includes a lens, a lens attachment frame that includes a lens holding portion for holding the rim of the lens, and a holding case that sandwiches the lens attachment frame movably in a plane direction perpendicular to an optical axis of the lens. The lens attachment frame includes a shaft portion on the periphery of the lens holding portion, functioning as a fulcrum at a time when the lens attachment frame moves in the plane direction. The holding case includes a shaft supporting portion for supporting the shaft portion and frame guide grooves for sandwiching the lens attachment frame. The position of the lens is adjusted by operating a lug portion by fingers or the like with the shaft portion as a fulcrum. Then the adjusted position is fixed by injecting an adhesive into wedge spaces formed of opposing adhesion grooves.

Abstract: A method for investigating a cause of decrease in frequency of abnormality detections for a certain device mounted on a vehicle, wherein when a plurality of abnormality detection conditions are satisfied, the abnormality detection for the certain device is performed to determine if the certain device is in failure, the method includes (i) when the frequency of the abnormality detections is below a predetermined value, disabling one of the abnormality detection conditions; (ii) when the abnormality detection conditions except the disabled abnormality detection condition are satisfied, performing an abnormality detection for the certain device; (iii) repeating the step (ii) a plurality of times; and (iv) determining if the disabled abnormality detection condition at that time is the cause of the decrease in the frequency of the abnormality detections, based on frequency of the abnormality detections in the step (iii).
