Title: Electron gun for braun tube
Inventor: MIYATA YOSHIHIKO
IPC: H01J29/48
Filed: 1981-05-29
Abstract: PURPOSE:To enable an electron gun having a large-aperture electron lens to be easily assembled with high accuracy by providing the end of a large-inner- diameter electrode with a recessed part, which is made close to the axis of the  electron gun to such a degree that it doesn't touch the smaller outer diameter  part of a two-outer-diameter electrode, and making the large-inner-diameter electrode to be supported by an insulating member by means of a projection  supporting part provided at the said recessed part. CONSTITUTION:By making the outer diameter (d) of a third-grid-projection supporting part 53 smaller than the inner diameter (D) of a fourth grid 6, the part 53 can be easily passed through the end of the grid 6 by rotating the diametral part of the part 53 apart from the diametral part of a fourth-grid-projection supporting part 62 (a recessed part 61) at an appropriate angle of (theta). After the passing of the part 53, the rotational angle (theta) is returned back to zero so as to make the electrodes to be coaxially supported by an insulating member 7. In assembling the electron gun of this invention, there is no work of connecting two parts divided in the axial direction into one electrode. Besides, any axial shift which might be caused when only one electrode is used is prevented, and the number of assembling processes is reduced.

Title: Manufacture of carbon product
Inventor: MIYAUCHI MASAYUKI
IPC: C04B35/52
Filed: 1979-06-29
Abstract: PURPOSE: To obtain a molded calcined carbon product of uniform quality such as an electrode by adding a small amount of very finely powdered silica to carbonaceous paste.  
     CONSTITUTION: About 0.1W2.0% very finely powdered silica of about 10W20μ particle size is added to carbonaceous paste contg. coke particles, etc. and mixed to provide thixotropic properties to the paste. This paste is then molded, calcined, and optionally graphitized to manufacture a graphite electrode, a carbon block for a heat and corrosion resistant material, a material for various molds, or the like. Since the viscosity of the paste is not increased during the molding and less binder settles in the calcining process, the quality such as the density of the product is rendered uniform.

CONSTITUTION:In the case of normal work, when a change-over valve 7 is changed over from N to L or M, discharge pressure of a pump 2 becomes higher by the pressing force of a spring 15 connected to a regulator 16 than the load pressure of an actuator 3 because of a restrictor 20 so that the change- over pressure of a valve 13 is controlled. Additionally, when a ficon curve is made variable, a valve 18 is changed over with an instruction 19, hydraulic pressure from a pump 17 is supplied to the regulator 16, the pressing force of a valve 13 is lowered by way of changing the mounting length of the spring 15 and the flow from the pump 2 to the actuator 3 so that the ficon curve changes from (e) to (f). Consequently, it is possible to improve minute operability.
