Title: Reactive gas ionization promotion type ion plating method
Inventor: URAMOTO JOSHIN
IPC: C23C16/50
Filed: 1988-04-06
Abstract: PURPOSE:To improve the ionization efficiency of reactive gas by allowing the reactive gas to flow between the intermediate electrodes of a pressure gradient type discharge source in the title method in which the above-mentioned discharge source is utilized. CONSTITUTION:The ionization promotion type reactive gas is introduced 7 between the intermediate electrodes 2, 3 provided to the interval 4 of a cathode 1 of a pressure gradient type discharge source and a hearth 4. For example, in the case of performing TiN coating while utilizing 200A discharge of gaseous Ar by this method, the flow rate of N2 is sufficiently regulated to about 1/5 in comparison with the ordinary method in which the reactive gas is directly introduced 8 into a vacuum vessel 10 and the partial pressure of the reactive gas at this time can be regulated to several fractions of pressure. As this reason, since the pressure of reactive gas introduced 7 between the intermediate electrodes 2, 3 is 30-100 times higher than the case performing the introduction 8, ionizing collision against electron current of discharge is promoted and it is supposed that the ionization efficiency of the reactive gas is remarkably improved as a result.

Concretely, the step motor 80 rotates normally, the carriage 34 is thereby made to advance and a printing head 28 comes into contact with the printing surface of the printing paper 110. Thereafter the step motor 80 rotates reversely for a prescribed time, the printing head 28 is thereby moved backward at a prescribed distance, and a certain gap is formed to the printing paper 110. When the printing head is in contact with the printing paper 110, the thickness of the printing paper 110 is detected, the head gap is made to be an appropriate value by the backward movement at a prescribed distance, and thus beautiful printing being excellent in quality can be obtained even when the thickness of the printing paper is varied.

Filed: 1979-07-05
Abstract: PURPOSE:To improve the stability of a positive electrode principally made of silver peroxide by allowing lead and aluminim to be contained in the alkaline electrolyte in a battery. CONSTITUTION:In the alkaline electrolyte of a battery having a positive electrode principally made of silver peroxide, lead and aluminium are contained. As lead, metal lead powder or a lead oxide soluble in alkali such as lead monoxide is used, which as aluminium, metal aluminium or an aluminium salt soluble in alkali such as aluminium hydroxide is used.

Potassium hydroxide is most suitable as the alkaline electrolyte. Therefore, even if a positive electrode made of silver peroxide having large activity is employed, the generation of gas can be reduced in quantity, and decomposition of silver peroxide is suppressed, and stability can thus be improved.
