Abstract: A head-mounted device to be worn on a user's head includes a first pressing member to press, for example, an occipital region, a second pressing member to press, for example, a parietal region, and first and second linear members connected to the first and second pressing members respectively. The first and second linear members are guided so that a change in lengths of the first and second linear members causes the first and second pressing members to move in the first and second directions respectively. An adjustment unit to adjust the lengths of the first and second linear members includes first and second wind-up units connected to a rotational operation member and to wind up the first and second linear members respectively.

Abstract: A head-mounted device mounted on a wearer's head has a first pressing unit to press against the wearer's head from a position of his/her medulla, a second pressing unit to press against the wearer's head in an opposite direction to a pressing direction of the first pressing unit, and a mounting unit to mount the head-mounted device on the wearer's head by adjusting at least one of the first pressing unit and the second pressing unit.

Abstract: To shield a frame area 203b, a frame-like shield member 501 is superimposed over an LCD 203 while being separated from the LCD 203 by a distance L. The distance L satisfies L<2×(B?A)×f/D where f is a focal length of an optical system, D is a human pupil diameter determined statistically in advance, B is a width of the frame area, and A is a value determined statistically in advance as a width which will not be able to be shielded on a side of the frame area to be shielded by a side of the shield member.

Abstract: A light source device includes at least one dot-like light source, a substrate where the dot-like light source is arranged, and a reflection member which is arrange to be in contact with a light-emitting surface of the dot-like light source and cover the light-emitting surface. The reflection member further includes an opening to pass therethrough a beam emitted from the dot-like light source.

Abstract: This specification discloses a mounting mechanism for a display portion onto the head in which the movement range of a wearer is not restricted and it becomes possible to make the display portion follow the head. This mounting mechanism has a head mounting portion for mounting the display portion on the head, a weight supporting portion mounted on any other body portion than the head for supporting part of the weight of the head mounting portion, and a connecting member for connecting the head mounting portion and the weight supporting portion together so that the head mounting portion may be movable following the movement of the head.

Abstract: The present invention provides a surface treated steel sheet including a steel sheet; a plating layer containing at least one metal selected from the group consisting of zinc and aluminum on a surface of the steel sheet; and a film on the plating layer, the film containing at least one metal selected from the group consisting of Al, Mg, and Zn, a tetravalent vanadium compound, and a phosphoric acid group. This surface treated steel sheet exhibits excellent corrosion resistance and excellent surface appearance without containing hazardous substances, such as hexavalent chromium, in the film.

Abstract: Disclosed howling eliminating apparatus comprises frequency analyzing means 32 for detecting a frequency which causes howling, band eliminating means 20 for eliminating a band including the howling frequency detected by the frequency analyzing means, and controlling means 30 for controlling both the frequency analyzing means and the band eliminating means in their characteristics. The frequency analyzing means is controlled to divide input frequencies into a plurality of wide bands, detect howling status in each of the divided wide bands to isolate one wide band suspected to include the howling frequency. When the one wide band causing the howling is isolated, the frequency analyzing means divides the suspected wide band into a plurality of narrow bands, and detects the howling frequency in one of the narrow bands. The band eliminating means is controlled to eliminate the narrow band including the howling frequency. The apparatus thus shortens the time it takes to detect howling with a minimum of hardware.

Abstract: A zinc-plated steel sheet having a resin coating film formed on the surface is obtained by forming a chromate treating layer on the surface of a base steel sheet plated with zinc or a zinc alloy, said chromate treating layer being deposited in an amount of 1 to 200 mg/m.sup.2 in terms of metal chromium, followed by forming a resin coating film on the chromate treating layer in a thickness of 0.1 to 5 .mu.m, said resin coating film being based on a composite resin material including a resin composition and at most 50% by weight of silica, said resin composition containing an ethylene-based ionomer resin and a silane compound having in the molecule a single silicon atom and 2 to 4 silyl ether bonds and/or its condensate.

Abstract: A zinciferous plated steel sheet excellent in press-formability and corrosion resistance, which comprises: a steel sheet, a zinciferous plating layer formed on at least one surface of the steel sheet, a chromate film formed on the zinciferous plating layer, and a resin film formed on the chromate film. The resin film comprises a solvent-base thermosetting resin, a solid internal lubricant and a rust-preventive pigment. The solvent-base thermosetting resin comprises: (A) urethane prepolymer containing a hydroxyl group, and (B) at least one of a block polyisocyanate compound and an amino resin as a curing agent. The urethane prepolymer containing a hydroxyl group comprises: (a) at least one of polyether polyol, polyester polyol and polyether-polyester polyol, (b) an isocyanate compound, and (c) dihydric alcohol.

Abstract: A frost damage proofed pile for installment in a frigid district where the pile is subjected to a freezing and frost heaving force, such as permanently or seasonally frozen soil terrain. A tubular sheath member is fitted over the pile surface and has a length longer than the thickness of an active or seasonally frozen soil layer of the terrain in which the pile is installed. At least a portion of said length of the pile is formed as an extensible section, and at least the lower end of said sheath member is secured to the pile at or below a position corresponding to the bottom region of said active or seasonally frozen soil layer. A fluid material is filled in a space defined between the pile and the sheath member. The frost heaving force caused to exist upon freezing of the active or seasonally frozen soil layer as well as negative friction caused to exist in summer are inhibited from affecting the pile due to sliding of the sheath member relative to the pile.
