    摘要： A direct heating cathode for electron guns and a process for producing such a cathode are disclosed. The above direct heating cathode achieves a high current density, extends the expected life span and simplifies the cathode producing process. In the process for producing the above cathode, powdered iridium (Ir) as a basic ingredient is mixed with powdered cerium (Ce) as a subsidiary ingredient at a given mixing ratio into a powdered metal mixture. The powdered metal mixture in turn is applied with a mechanical impact through high energy ball milling, thereby being mechanically alloyed into alloy powder. The alloy powder is compressed with a given pressure, thereby being formed into an alloy pellet. The alloy pellet in turn is heated to remove residual gases from the pellet. Thereafter, the electron emitting performance of the pellet is tested.

The above process mechanically forms the hydrogen occluded alloy having improved initial discharging characteristics. In the above process, either a powdered LaNi.sub.5 alloy or rare earth metals, such as la, Ce, Pr and Nd, and a powdered CaCu.sub.5 alloy of Mm-Mn-Ni-Al-Co alloys is mixed with a powdered Laves alloy of Zr-Mn-V-Cr-Ni alloys into a powdered alloy mixture. Thereafter, the alloy mixture is applied with a mechanical impact by a high energy ball mill with an attritor, thereby mechanically forming the hydrogen occluded alloy. The above process easily controls the manganese component while producing the hydrogen occluded alloy through the mechanical alloying.

    摘要： A cathode for an electron tube includes a layer of a electron emitting substance containing alkaline earth metal oxides containing 0.01--20.0 wt % of both a lanthanum compound and a magnesium compound or a lanthanum-magnesium compound disposed on a base metal including nickel as a major component and tungsten as a minor component. The tungsten prevents embrittlement and ensures a continuing supply of fill barium in the electron-emitting substance. The cathode enjoys full interchangeability with the conventional oxide cathode and a 15-30% longer life span.

    摘要： A method of fabricating a microlens includes forming layer of photoresist on a substrate, patterning the layer of photoresist, and then reflowing the photoresist pattern. The layer of photoresist is formed by coating the substrate with liquid photoresist whose viscosity is 150 to 250 cp. A depth sensor includes a substrate and photoelectric conversion elements at an upper portion of the substrate, a metal wiring section disposed on the substrate, an array of the microlenses for focusing incident light as beams onto the photoelectric conversion elements and which beams avoid the wirings of the metal wiring section. The depths sensor also includes a layer presenting a flat upper surface on which the microlenses are formed. The layer may be a dedicated planarization layer or an IR filter, interposed between the microlenses and the metal wiring section.
