Abstract: A vehicle door lock device includes: a latch mechanism engaged with a striker provided on a vehicle body; and a bracket supporting the latch mechanism on a door of a vehicle. The bracket includes a base plate including a latch holding portion holding the latch mechanism and fixed to the door, and an extension plate extending in a direction intersecting the latch holding portion. The extension plate includes a fastening hole for fastening the extension plate to the door in a thickness direction of the door, a first bead-shaped portion extending in a direction in which the extension plate extends, and a second bead-shaped portion extending in a direction intersecting the first bead-shaped portion. A plurality of the first bead-shaped portions and a plurality of the second bead-shaped portions are arranged in a lattice pattern.

Abstract: A vehicle door lock device includes: an actuating lever linked to an electric motor, rotatable in a rotation regulating range, rotating in one direction toward a closing position on one end side of the rotation regulating range, thereby holding, in a complete-closing state, a door having been in a half-closed state, and rotating in the other direction toward a release position on the other end side, thereby releasing the holding of the door in the complete-closing state; a first neutrality detecting switch generating a first neutrality detection signal having logic switched at a first neutral position; and a second neutrality detecting switch generating a second neutrality detection signal having logics switched at a second neutral position and a release start position which are a boundary position of the neutral region on the closing position side, and a boundary position of the neutral region on the release position side, respectively.

Abstract: As an acidic liquid composition capable of forming an anticorrosive film having an appearance and corrosion resistance comparable to the anticorrosive film formed by chromate treatment on a substrate which has a metallic surface and a complicated shape, a chromium-free acidic liquid composition for reactive chemical conversion treatment for use in forming an anticorrosive film on a metallic surface is provided, the composition comprising: at least one oxidative substance selected from a nitric ion and hydrogen peroxide; at least one carboxylic acid compound selected from the group consisting of carboxylic acids, carboxylate ions, carboxylates, and derivatives of carboxylic acids; an aluminum-containing substance; a zirconium-containing substance; and a sulfate ion, wherein the composition does not substantially contain an organic film-forming component.

Abstract: A finishing agent, which can provide a chromium-free surface treatment layer for use in forming an overcoat on an oxidation-resistant layer on a substrate, comprises an aluminum-containing substance in the form of at least one of a cation, a salt of the cation, and a coordination compound containing the cation; a zinc-containing substance in the form of at least one of a cation, a salt of the cation, and a coordination compound containing the cation; a chelating agent which is able to form a coordination compound with an aluminum ion; and a film-forming substance containing a first element selected from the group consisting of P, Mo, W, Ce, Mn, Si, Ti, Zr, and V. The preferable chelating agent is citric acid. The finishing agent may further contain an organic binder.

Abstract: An opening and closing member control device includes: a latch that pulls in or releases a striker; a displacement member that operates the latch through a latch operation mechanism and is displaced within a movement area including a close area, a release area, and a neutral area positioned between the close and release areas; a motor that displaces the displacement member; a rotation counter that counts a rotation amount of the motor; and a control unit that controls, based on the rotation amount of the motor, rotation of the motor to perform a first returning operation for returning the displacement member to a neutral position set in the neutral area from the close area after a close operation of the displacement member, and a second returning operation for returning the displacement member to the neutral position from the release area after a release operation of the displacement member.

Abstract: A corrosion resistant member has a chemical conversion treatment film with a two-layer structure formed atop a metal substrate plated with zinc or zinc alloy plating. The two-layer structure comprises a lower layer containing Cr formed on the surface of the plating and an upper layer containing SiO2.
