Title: Electron gun
Inventor: MARUYAMA MASANORI
IPC: H01J3/02
Filed: 1981-08-19
Abstract: PURPOSE:To heighten density of an emission current of a cathode only in the central region while lowering it in the periphery thus to improve durability and reliability of the cathode by a method wherein the central region, in which an opening of the first electrode facing the cathode is located, is made to rise as opposed to the periphery away from the opening and a gap between the cathode and the first electrode is so made as to be narrow in the center and broad in the periphery. CONSTITUTION:The central region, wherein an opening of the first electrode is located, in made to rise on the side of a cathode and a gap between said central region and the cathode 1 is left as before, whereby the gap between the periphery and the cathode is made larger as compared to before and the plate electrode facing the cathode face is so formed as to the more go away when it is the more distant from the central axis 4. When electric potential E has a fixed value, the density of an emission current of the cathode reduces in inverse proportion to a square of the gap (d) between the cathode and the first electrode, so that the density of the emission current in the periphery away from the center of the cathode face can be held small thus to improve durability and reliability of the cathode and concurrently to hold the current whole flow quantity small.

Title: Optical disk device
Inventor: TAKESHITA NOBUO
IPC: G11B7/08
Filed: 1993-05-31
Abstract: PURPOSE:To obtain an axial angle adjusting device for optical parts having good frequency characteristics and high mass-productivity in the optical disk device mounted with an axial slide and turning type objective lens actuator. CONSTITUTION:Under the state of fixing one end of a supporting shaft 103 for the objective lens actuator, a cover 120 holding the other end is moved in a plane along a parallel plane to a disk and is fixed, so that the supporting shaft 103 is inclined at a minute angle, thus resulting in angle adjustment of the objective lens 111. The adjustment is simplified by converting the angle adjustment in the biaxial directions into the translation adjustment in the biaxial directions. In addition, when the supporting shaft having low rigidity is used, and the supporting shaft is bent by moving the end of the supporting shaft, so as to perform the angle adjustment, the similar effect is also obtained.
