In vacuum depositing apparatus, especially for the manufacture of magnetic tapes, a substrate holder is disposed in the form of a cooling cylinder, and in the path of the vapor stream there is a mask for the purpose of geometrically restricting the vapor stream. In order to prevent any condensation of vaporized material in solid form, the surface of the mask facing the vapor stream is not aligned horizontally, and its lowermost edge lies within the projected surface of the crucible opening. The ...

An evaporator for depositing films in a vacuum consisting of a crucible for containing an evaporant and adapted to be heated by a heater. A tube is provided for forming a directional flow of evaporant toward a substrate. The tube has a mounting structure at both ends so that the tube can be alternately mounted in the crucible at each end about a transverse symmetry plane.

Apparatus for automatically depositing parallelepipedic articles into an upwardly open collecting hopper, carton or the like, including a pair of article support members pivoted in spaced opposed facing relation, the support members respectively having spaced upper and lower jaw members defining respective opposed channel areas. The support members reciprocate in synchronous opposed pivotal movement between an article supporting position wherein their channel areas open in facing relation for re...

Disclosed is a thin film deposition apparatus for depositing a thin film on a display panel including a deposition source having a groove in one surface wherein the groove is filed with a thin film material to be deposited on the panel, a heater applying heat to the deposition source so as to sublimate the thin film material, and a mask loaded on the deposition source so as to cover the groove of the deposition source, the mask having a plurality of holes to adjust a deposition quantity of the t...

This disclosure relates to depositing of flowable materials such as cookie dough, jams, and the like, the depositing being carried out by forcing the flowable material out through an effluent port of a hopper onto a continuous belt which is moved intermittently between each depositing cycle. A cam wheel and a cam follower finger intermittently force the flowable material out through the effluent port. The cam follower is shaped so as to create suction at the effluent port after the depositing cy...

A method for the controlled electrodeposition of lead to a desired thickness on a cathode plate in an electrolytic bath including the placement of a cathode disposed in spaced apart, vertical, parallel relation between a pair of anode plates in said bath, supporting said cathode and anodes with electrically conductive support frames around the entire peripheral edges thereof, and providing insulating material on the outer surfaces of said support frames exposed to said electrolytic bath to form ...

Apparatus for depositing a thin layer of a conducting or partially conducting material on the surface of a body which includes a vacuum chamber, a high-frequency coil located within the chamber for generating an electromagnetic field and means for supplying gas into the chamber in the vicinity of the electromagnetic field. A substantially tubular wall, which may be in the form of a cylinder or a truncated cone, is disposed within the high-frequency coil and electrically connected thereto. The tu...

A process for coating a metal surface, such as a reduced iron ore, with an adherent layer of carbon is provided. The metal is contacted with carbon and a mixture of olefins. Suitably, the olefin mixture contains polyenes and dienes, preferably cyclopolyenes and cyclodienes. The process is conducted at temperatures ranging from about 200.degree. F. to about 600.degree. F. The metal surface, coke, and the olefinic mixture is brought into contact by any solid-liquid contact means, e.g., by spraying...

On spray-forming metals onto a substrate from which the sprayed coating is to be detached, unwanted adhesion may occur, even to a smooth substrate. Conversely, if the coating is meant to adhere, it may accidentially delaminate, even from a roughened substrate. By vibrating the substrate, marginally adherent splats will be encouraged to detach themselves while, on the other hand, well adherent splats will not be affected.

The present invention discloses a method for coating a polyimide precursor on an electronic structure incorporating the use of a silicon coupling agent without any bubble defect in the film deposited. The method can be carried out by flowing at least one inert gas through a deposition chamber and thereby keeping the relative humidity in the chamber at below 25% to carry away the formation of any water molecules and water vapor to prevent the formation of bubbles in the film deposited.
