The sliding member according to the present invention includes: a base material; and a sliding film that covers a surface of the base material and constitutes a sliding surface, and is used under a wet condition where lubricant oil exists. The sliding film according to the present invention is a laminated film that includes: an underlying layer formed on the surface of the base material; and an outermost layer formed at least on a part of the underlying layer. This outermost layer is characterized by including specific boron-containing amorphous carbon (specific B-DLC) that contains 4-50% B and 5-50% H when the outermost layer as a whole is 100 at %. This specific B-DLC itself wears away during the sliding to smooth the sliding surface, and an excellent low friction property is exhibited. The underlying layer of the specific B-DLC contributes to improvement in the wear resistance property of the sliding film.

A sliding member includes: a substrate which has a sliding surface sliding under the presence of lubricating oil; and a film which is fixed to at least a part of the sliding surface. The film contains carbon (C), titanium (Ti), and boron (B), is obtained by repeatedly and alternately layering a first layer containing amorphous carbon as a principal component and a second layer containing C and Ti as principal components, and has hardness of 18 GPa or more.

In an adjusting method for a cathode position of an electron gun, an apex point of a dome-shaped cathode is detected and then a positional adjustment is executed by moving a first grid in a X-Y direction so that a center of a grid aperture is coincided with the position of the apex point, at first. Next, a sleeve ring and a collar portion of a sleeve holder are welded together by a laser beam. The a dgk-vale adjustment is done so as for a gap between first grid and apex point of the cathode to be a predetermined value and welded by irradiating the laser beam to a superposed position of the cathode structure and the sleeve. According to the present invention, these positioning adjustment and the dgk-value adjustment are able to be executed independently.

In a method of manufacturing a sliding member, a granular spraying material is sprayed on at least a part of a surface of a body portion made of a structural material in at least partially fusing condition and in the direction which is parallel to or diagonal to a sliding surface. Then, a sprayed layer is formed by depositing the spraying material in the direction which is perpendicular to the sliding surface. The sliding surface is a section of the deposited spraying material which is obtained by grinding or cutting the sprayed layer in depositional direction. A piston comprises a piston body having a broad groove which is broader than a ring groove, a sprayed layer comprising a lower sprayed layer which is formed by spraying the spraying material in the direction which is diagonal to an outer periphery of the broad groove and which contains higher ratio of spraying particles having low fusion temperature, and an upper sprayed layer which is formed by spraying the spraying material in the direction which is perpendicular to the outer periphery of the broad groove and which contains higher ratio of spraying particles having high fusion temperature, and a ring groove which is formed by grinding or cutting the upper sprayed layer in depositional direction. Therefore, excellent wear resistance and the like can be obtained.

The present lubricant compositions comprise a mixture of graphite, molybdenum disulfide and polytetrafluoroethylene in specified proportions within a matrix of an organic resin. When applied to surfaces that are in sliding contact with one another the compositions exhibit high wear resistance, good initial conformability, and a coefficient of friction following use that is lower than the initial coefficient of friction. The compositions are particularly suited for application to engine pistons.

A safety panel that is bonded to a front surface of a panel of a cathode ray tube envelope can be peeled easily without damaging the safety panel. A cathode ray tube (5) has a safety panel (3) that is bonded to a front surface of a panel (2) through a resin layer (4). When the safety panel (3) is to be peeled, the surface of the safety panel (3) is rapidly heated by a sheet-shaped infrared heater (6) and the resin layer (4) is heated up to a melting point and softened by the heat conduction. Then, a spatula (7) is inserted into a spacing between the safety pane (3) and the resin layer (4) to thereby peel the safety panel (3).
