Title: Powder coating device
Inventor: KITAGAWA MASAYOSHI
IPC: B05C19/06
Filed: 1993-01-25
Abstract: PURPOSE:To obtain a powder coating device which can apply variably to any capacity instantaneously by arranging an upper pipe, an injector on the upper end of this upper pipe, an inner pipe which is open against the jet aperture of a jet nozzle, a powder fluidization device at the bottom of a powder hopper and an activation air operation part. CONSTITUTION:If a powder fluidization device 6 is activated to fluidize powder paint P in a powder hopper 2, and an activation air is supplied to set a jet nozzle to work, powder around a jet aperture 51 is sucked by ejector action and is induced into an inner pipe 25. Thus the powder is carried from the tip to the upper pipe and reaches a powder nozzle 1 passing through a powder hose 3. A compressed air sent by pressure into the powder hopper 2 fluidizes the powder paint P, and part of the powder paint P is scattered into the powder hopper 2 passing through a clearance C from the lower end 24 of the upper pipe 22. But the remaining equivalent is induced into the inner pipe 25 from the periphery of the jet nozzle 5 together with the fluidized powder paint P, and proceeds to the upper pipe 22. Consequently, an air current energy is activated to induce a strong ejector action.

Abstract: PROBLEM TO BE SOLVED: To best conceal a duplicatingly entered secret information and make it possible to read the information with a simple method by a method wherein a self-coloring means consisting of de-coloring type temperature indicating agent microcapsules, developer and coloring agent microcapsules is applied to the predetermined part of a base material surface. SOLUTION: A self-coloring means V formed by laminating a de-coloring type microcapsule layer, a developer layer and a coloring agent microcapsule layer in the order named is applied to a secret information entry part S provided at the predetermined part of a base material surface. Under the above-mentioned condition, when a password is entered in a secret information entry part S' of a top form 10, the password is duplicatingly entered in the secret information entry part S of a self-coloring form 1 constituted as an under form 11 by means of the self-coloring means V. Since the temperature indicating agent colors at normal temperature, no password can be confirmed. At the reading of the password, hot air is blasted against it or it is placed on a heating plate.  In order to read the password, a low cost and compact tool such as the blasting of hot air against the password, the placement of the password on a heating plate or the like is employed so as to keep a self-coloring form with the simple method at the temperature higher than the de-coloring temperature of a temperature indicating agent in order to decolor the de-coloring type temperature indicating agent, resulting in allowing to read the password.
