Abstract: A light guide body includes a light introduction member (12) and a light reflection member (11), and a side reflection surface (14) for reflecting introduced light to an opposite region which is on the opposite side across an opening (13) is formed on a side surface part of the light reflection member (11). A groove part for guiding the introduced light toward a direction of a light emitting pointer (24) is formed around the opening (13) in the light reflection member (11). The groove part includes a first groove part (P1) and a second groove part (P2) around the opening (13). The first groove part (P1) includes a plurality of grooves oriented in a direction almost orthogonal to the introduced light, and the second groove part (P2) includes a plurality of grooves having a predetermined angle relative to the grooves of the first groove part (P1).

Abstract: An illuminating device, for illuminating display designed parts on a display panel, includes at least one light source arranged at a rear side of the display panel, and a light guide body having a light guide portion for guiding the light toward its outer-circumferential portion to output the light toward the display designed parts through a front surface of the light guide portion. The outer-circumferential portion has an outer-circumferential side wall surface at is outer end. The light guide portion has at least one projecting portion projecting from the outer-circumferential side wall surface. The projecting portion is provided with a reflecting side surface formed along the outer-circumferential side wall surface so that the reflecting side surface can reflect the light traveling in the light guide portion to be outputted through the front surface of the light guide portion.

Abstract: A lighting device, for illuminating display designed parts on a display plate arranged parts at-least-partially around a center axis, includes a light source for emitting light and arranged at a rear side of the display plate, and a light guide body having at least one light guide portion including an inner portion and an outer portion. The inner portion has a rear side surface for receiving the light from the light source and a front side surface with a curvature for reflecting the light to change a forward-backward direction of the flight inputted from the light source toward an outwardly radial direction to guide the light so that the light can travel in the outer portion in approximately radial directions centered on the center axis and be suppressed from diffusion from a central line passing through though the center axis and the light source.

Abstract: An inkjet recording medium having a recording layer including a pigment and a polyvinyl alcohol on an air-permeable support, wherein inkjet recording medium is made by coating a treatment solution on the recording layer, wherein the treatment solution has the action of solidifying the polyvinyl alcohol in the recording layer when it is in the wet state, and then bringing the recording layer into pressure contact with a heated mirror surface while it is still wet. This treatment solution is a mixed solution of borate/boric acid, wherein the blending ratio of the borate and boric acid in the treatment solution is 0.25/1 to 2/1 by weight ratio.

Abstract: An inkjet recording medium having a recording layer comprising a pigment and a polyvinyl alcohol on a porous support, wherein a treatment solution having the action of solidifying the polyvinyl alcohol in the recording layer when it is in the wet state is coated thereupon, and the recording layer is then brought into pressure contact with a heated mirror surface while it is still wet. This treatment solution is a mixed solution of a borate/boric acid.

Abstract: Recyclable light proof and moisture proof papers with excellent moisture proofness and light proofness and especially with excellent repulpability during waste paper recovery are provided, which have a single repulpable and recyclable light proof and moisture proof layer on at least one side of a base paper using neither aluminium foil nor an aluminium deposited film, wherein said light proof and moisture proof layer contains 3-70 parts by weight (solids) of a light proof agent and 1-10 parts by weight (solids) of a wax per 100 parts by weight (solids) of a synthetic resin having a gel fraction of 90% or more.

Abstract: A vehicular meter unit includes an analog meter fixed only to a circuit board. A pointer connected to a shaft of the analog meter points a scale printed on a dial plate. A housing has a top plate and a peripheral wall perpendicularly extending from a periphery of the top plate. The dial plate is connected to the top plate without using screws. This arrangement improves the productivity and the luminance characteristic of the vehicular meter unit and suppresses the influence due to the thermal deformation of the dial plate.

Abstract: A ship construction comprises a symmetrical hull having two screw propellers which are symmetrically arranged in respect to the longitudinal central plane of the hull. A rudder is mounted aft of the screw propellers and preferably in the central plane. The propellers and the rudder are so dimensioned that the diameter of each propeller is less than the spacing between the center lines of the two propeller shafts. In addition, the distance between the axes of the propellers is equal to or less than the diameter of each propeller plus the thickness of the rudder. The arrangement provides an improved propulsive efficiency without loss in maneuverability.
