Filed: 1990-05-16
Abstract: PURPOSE:To achieve high luminance and long life of a discharge tube by providing a glow discharge electrode around each arc discharge electrode, and electrically connecting the glow discharge electrode to the terminal of one arc discharge electrode. CONSTITUTION:A transparent glass tube 1 is provided at both end portions 1a, 1b with filament coil electrodes 2a, 2b and funnel-shaped sintered electrodes 3a, 3b in such a manner that the sintered electrodes 3a, 3b surround the respective filament coil electrodes 2a, 2b. Each of the sintered electrodes 3a, 3b is supported at its root portion by lead wire 4a, 4b and is electrically connected at one end thereto but is electrically released at the other end. The sintered electrodes 3a, 3b with large thermal capacity are connected in parallel to the respective filament electrodes 2a, 2b. Therefore the filament electrodes 2a, 2b are not heated to high temperature and evaporated particles are restrained from scattering and are captured by the sintered electrodes 3a, 3b even when scattering and are not attached to the inner surface of the glass tube 1 and particles of electron-emitting material captured by the sintered electrodes 3a, 3b exhibit their effects again. High luminance and long life of the discharge tube are thus obtained.

Title: Breaking control device for broken type shield excavator
Inventor: ISHII TOSHIHISA
IPC: E21D9/093
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To dispense with enlargement of displacement and an increase in the number of broken type jacks so as to reduce cost by bending a shield body by the expansion of a plurality of broken type jacks that connect a front hull to a rear hull. SOLUTION: Variable displacement hydraulic pumps 5A, 5B output operating oil discharge signals to pump inclined rotation control devices 6A, 6B at the same discharge as the pressure receiving area ratio of broken type jacks 3J1 -J4. Corresponding change-over valves 7A, 7B of the broken type jacks 3 in the symmetrical positions of a shield center axis are opened/closed by operation signals from lateral and vertical bending operation parts 12P, 12Q. In this case, the other corresponding change-over valve 7B is put in an opening/closing position in the opening/closing position of one corresponding change-over valve 7A of the jack 3. The respective expanding-contracting strokes of the jacks 3J1 , J2 therefore become equal to those of the jacks 3J3 , J4.  A shield body is thereby bent with an axis, orthogonal to the shield center axis, as a bending rotation center axis, so that the cost of the jacks 3 can be reduced.
