  • Film forming apparatus
    Patent number: 5149415
    Abstract: Herein disclosed is a film forming apparatus, in which a magnet for generng the lines of magnetic force generally at a right angle with respect to opposed cathodes is disposed at one of the cathodes to shorten the distance from a passage hole through a conduit to an object by the thickness of the magnet, thereby to pass metal particles efficiently. At the same time, a holed plate is supported elastically and in close contact with the object to form a film contouring the shape of the hole of the holed plate correctly. Moreover, the holed plate is made thinner than its diameter to permit sufficient passage of the metal particles through the hole of the holed plate thereby to form a film efficiently. In the film forming apparatus of the present invention, moreover, the magnet of the vacuum chamber at the side of the conduit of the prior art can be dispensed with to make unnecessary the drilling of the magnet and to reduce the number of parts.

  • Method of correcting defect of patterned article
    Patent number: 4931307
    Abstract: A method of correcting a missing defect of a patterned film formed on an icle is carried out by steps of providing an operative vacuum chamber having a pin hole, positioning an area of the missing defect outside the vacuum chamber in registration with the pin hole, operating the vacuum chamber to cause therein cold cathode discharging to generate particles, and directing a stream of the particles through the pin hole onto the area of the missing defect to deposit thereon a corrective film of the particles.

  • Process for accumulating and storing light energy and releasing the same therefrom for utilization
    Patent number: 4507561
    Abstract: A light absorbing matter is irradiated by light ranging from ultraviolet to infrared and absorbed light energy causes the matter to be raised to an excited energy state. The excited state is then locked by maintaining the temperature of the matter at a predetermined value. Light energy thus stored can be released for utilization by changing the value of the temperature from the predetermined value.

  • Method for forming a dental caries preventive coating
    Patent number: 4324630
    Abstract: In a discharge space are formed neutral or charged particles of metal, alloy, semiconductor or insulator. The particles thus formed are guided through a duct so that they reach a surface of a tooth and form a caries preventive coating covering the surface of the tooth.
