摘要:
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.

摘要:
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. The solid internal lubricant comprises a polyethylene resin, and the content ratio thereof is within a range of from 1 to 30 weight parts relative to 100 weight parts of a solid component in the solvent-base thermosetting resin. The rust-preventive pigment comprises at least one of a chromate compound or silica, and the content ratio thereof is within a range of from 3 to 30 weight parts relative to 100 weight parts of the solid component in the solvent-base thermosetting resin.
摘要:
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.

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.

摘要:
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.
