The invention relates to a protective device to be utilized on the handlebar of a vehicle equipped with control levers mounted on the handlebar adjacent to the handlebar grips. The device of the invention prevents control levers from imparting damage to the surroundings when the vehicle is transported. The device of the invention further protects the control levers and grips from damage by contact with nearby objects during transportation of the vehicle. The device of the invention further keeps a brake control lever in the fully pulled position, thus actuating the brake and preventing rotation of the braked wheel or wheels.

[Expression 1]

k.sub.1′+k.sub.2′+k.sub.3′≤9.3 N/mm  (1)

[Expression 2]

0.55≤k.sub.1′/(k.sub.1′+k.sub.2′+k.sub.3′)  (2)

wherein k.sub.1′ is a value obtained by dividing an equilibrium coefficient k.sub.1 by a thickness of a test piece, and k.sub.2′ and k.sub.3′ are values obtained by dividing viscous coefficients k.sub.2 and k.sub.3 by the thickness of the test piece, respectively.

A vacuum formed part includes at least two layers with one layer including a catalyst and the other not including a catalyst. At least one of the layers is formed by applying a slurry to a die or mold and applying a vacuum to the die or mold. The other layer may be formed from a slurry or may be provided onto the die or mold in the form of a fiber mat or blanket.

A method for producing a latex composition, the method comprising a provision step of providing a conjugated diene polymer latex; a preparation step of adding a sulfur-based vulcanizing agent and a xanthogen compound to the conjugated diene polymer latex to prepare a latex composition before aging; and an aging step of, after the preparation of the latex composition before aging, aging the prepared latex composition before aging through storing of the latex composition at a temperature of 5 to 60° C. for 12 hours to 14 days, wherein the pH of the latex composition after 12 hours from the start of aging in the aging step is controlled to 9 or more.

A filming method of probe and the probe made by the filming method, the method includes following steps: spraying hydrophilic matrix material on the rigid member; injecting liquid polyethylene glycol into an interior, letting the polyethylene glycol coagulate; cutting out the solid polyethylene glycol, letting the cutting surface and the perimeter of the rigid member to be formed in a smooth plane; letting the wedge end of the rigid member insert a liquid latex vertically for immersion, picking up the rigid member and dripping residue, air drying the adhesive layer of the rigid member; upward setting the wedge end of the rigid member, and letting the latex film be heated, melting the solid polyethylene glycol and letting the polyethylene glycol drain away. The method can minimize the nonlinear deviation, simplify the technological process, improves product quality and manufacturing efficiency.
