IPC: C23C16/34
Filed: 1989-08-01
Abstract: PURPOSE:To control the corrosion of the surface of a base material and to coat the surface in a short time at the time of coating the surface of the corrosive metallic base material with the reaction product of a gaseous reactant contg. metal halides by specifying the relation between the total concn. of metal halides and the temp. CONSTITUTION:A metallic compd. (e.g. TiB2) resulting from metal halides is deposited on the surface of a corrosive metallic base material (e.g. carbon steel and Al) in an atmosphere contg. the metal halides (e.g. BCl3 and TiCl3) by hot CVD to coat the material. In this case, the reaction temp. T ( deg.C) is adjusted to (-8C+740) to (-8C+765) (where C (%) is the total concn. of metal halides in gaseous reactant), and C is controlled to 2-7. As a result, the corrosion of the surface of the corrosive metallic base material is controlled without reducing the reaction rate, a corrosion layer is not formed, and hot CVD is applied under such conditions.

Title: Corrosion resistant strand for prestressed concrete and production thereof
Inventor: FUREDERITSUKU EFU HANTO
IPC: E04C5/01
Filed: 1983-10-28
Abstract: Concrete strengthening members, particularly prestressing tendons such as strands of steel wire, are provided with a strongly adherent plastic coating which may be substantially impermeable for improved corrosion resistance, and/or which may have embedded therein abrasive or grit-form particles to provide improved bond with the concrete, and particularly to provide controllable bond transfer in prestressing tendons of the pretensioned type. The plastic coating preferably is applied electrostatically in powder form, and fusion bonded by heat. The abrasive can be applied by spraying during a viscous state of the heated resin, and can be varied as to size and spacing density so as to control the surface condition and the bonding effect. Fusion and curing heat may come from preheating of the member before application of the resin powder, which preferably is a heat curable, thermosetting epoxy. Coating thickness and grit application are readily variable to meet particular requirements. Particularly advantageous results are achievable for high strength steel strands for prestressing concrete by pretensioning, facilitating their use where previously considered impractical or impossible.

IPC: B60J3/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To cushion impact at the time of lowering a stay into a lowest position by providing a motor-driven driving means for moving a pair of sliders in the mutually separating/approaching direction to elevate a stay through a pair of arms, and providing energizing means for rotating a pair of arms into the attitude orthogonal to the stay. SOLUTION: When a pair of sliders 6 are driven to move synchronously in the mutually approaching direction by motor-driven drive mechanism 8 from the state of a stay 5 being positioned in a lowest position in the attitude of a pair of arms 7 being orthogonal to the stay 5, a pair of arms 7 are respectively rotated onto the guide rail 4 side, and the stay 5 is lowered to wind a curtain 2 onto a winding device 3. When the stay 5 is lowered into a lowest position and driving of an electric motor 31 is stopped, impact is cushioned by the energizing force of a pair of energizing mechanism 9. Impact at the time of storage and impact at the time of lowering the stay into the lowest position can thereby be cushioned so as to improve durability of the motor-driven driving means.
