There is provided a method of manufacturing magnetic head sliders comprising the steps of cutting a material block, which may be of sintered ferrite or ceramic material, to form a core block and slider block. A groove is formed in the core block, which is bonded to the slider block using techniques to provide a magnetic gap. Thereafter the core block is machined to form a plurality of head cores, followed by machining the slider block to form in parallel a number of sliders, which are lapped and then sliced into individual magnetic head sliders. To prevent particles of material from the magnetic head sliders from separating from the sliders and causing deleterious effects, such as head crashes, a heat treating process is employed in which the slider block and core block are treated for from 3 to 20 hours at a temperature of from 100.degree. C. to 150.degree. C., at an ambient air pressure of from 1.5 to 5 kg/cm.sup.2 and at a relative humidity of not less than 60%. In one embodiment the heat treatment is performed immediately following the step of cutting the material to form the core block and slider block. In another embodiment, the heat treatment is performed immediately prior to lapping the sliders.

An X-ray tube comprises: an envelope which has a cathode at one end and an anode at another end of a barrel of a tubular insulating tube and which has a sealed interior; an electron gun which is arranged inside the envelope and has a shape that protrudes from the cathode; and a target which is electrically connected to the anode and generates X-rays when being irradiated with electrons emitted from the electron gun. With reference to an end position that is a projection of a position of an end on the anode side of the electron gun onto an inner wall of the insulating tube, a mean wall thickness of the barrel is greater on the cathode side than on the anode side.

An electron beam apparatus in which a spacer having a high-resistance film coating a surface of a base material is inserted between a rear plate having electron emitting elements and row-direction wires, and a faceplate having a metal back. The row-direction wires and the metal back are electrically connected via the high-resistance film. An electric field near an electron emitting element near the spacer is maintained to substantially constant irrespective of the positional relationship between the spacer and the electron emitting element near the spacer. When a sheet resistance value of the high-resistance film on a first facing surface of the spacer that faces a row-direction wire is represented by R1, and a sheet resistance value of the high-resistance film on a side surface adjacent to the electron emitting element is represented by R2, R2/R1 is 10 to 200.
