Title: Display tube for light source
Inventor: NAKANO MASAAKI
IPC: H01J63/06
Filed: 1990-07-25
Abstract: PURPOSE:To eliminate reduction of brightness and achieve a high brightness and a high contrast by providing a filter for transmitting visible light of one color, and a light emission surface for emitting the same visible light as the color which the filter transmits. CONSTITUTION:A matrix protruding lens 15b is integrally formed in the outer surface of a front panel 17. In addition, filters 18G, 18R which transmit only visible light emitted by light emission surfaces 5G, 5R corresponding to the protruding lens 15b are disposed between the light emission surfaces 5G, 5R and the front panel 17 respectively. Visible light emitted by the light emission surfaces 5G, 5R is thus selectively transmitted, and external light incidental to the front panel 17 can be damped. A display tube for a light source of a high contrast and a high brightness can thus be obtained.

Title: Liquid sealed vibration isolator
Inventor: MAENO TAKASHI
IPC: F16M7/00
Filed: 1989-08-02
Abstract: PURPOSE:To greatly prolong the service life of the subject liquid sealed vibration isolator and effectively prevent deterioration of the performance of this liquid sealed vibration isolator by manufacturing a vibration isolating rubber body to constitute a main liquid chamber and a rubber film to constitute a sub liquid chamber as separate bodies and by using a rubber material which is superior in ozone proof and gas permeation proof. CONSTITUTION:At the time of inputting vibration, the relative position of an inner cylinder 2 and an outer cylinder 1 changes and in concert with it, a main liquid chamber A deforms and sealed liquid flows to a sub liquid chamber B through a throttle passage F and causes the damping of vibration. At this time, a rubber film 4 forming a chamber wall of the sub liquid chamber B deforms in concert with the incoming and outgoing flow of sealed liquid, but as it is superior in ozone proof, it does not cause deterioration, and as it is also superior in gas permeation proof, it effectively prevents mixture of air in the liquid inside the sub liquid chamber B. Consequently, the vibration isolation performance of the liquid sealed vibration isolator can be well maintained.

Title: Optical amplifier
Inventor: SUZUKI NOBUO
IPC: G02B6/02
Filed: 1990-07-31
Abstract: PURPOSE:To increase optical amplification gain and to facilitate the remote stimulation of plural number of stages by changing the kind of impurity elements to be doped to respective optical amplifier sections in order to amplify signal light by plural stages of the amplifier sections. CONSTITUTION:The optical amplifier section 1 is a single mode fiber doped with Er<3+> in the central part of a core and the optical amplifier section 2 is a single mode fiber doped with Er<3+> and Dy<3+>, respectively. A 1st stimulating light source 3 is a semiconductor laser of 1.48 mum wavelength and a 2nd stimulating light source 4 is of 1.27 mum wavelength. Then, the 1st stimulating light is absorbed to the Er doped in the optical amplifier section 1 where he amplification of the signal light is executed under the induced release by the transition between electron states, but the 2nd stimulating light is hardly absorbed in the optical amplifier section 1 and is absorbed by the impurity elements doped in the optical amplifier section 2. The amplification of the signal is thus executed again. The gain is greatly increased in this way and the remote stimulation of plural stages of the optical amplifier sections is possible.

The electron gun 2 is used to perform welding of a substance 6 to be worked by accelerating an electron beam 5 by applying high voltage to thermions discharged through heating carried out with a cathodic power source 3 after they are controlled with a bias power source 4. When abnormal electric discharge develops within he electron gun 2, the output of an acceleration-voltage detector 7 changes, and the output is compared with that of a voltage setting device 8 by means of a comparing circuit 9. Only when the acceleration voltage becomes smaller than the set point by over 10%, a multivibrator 10 and a control transistor 11 work cutting off the high voltage circuit. Time during which the operation of the electron gun 2 is stopped is regulated to below 10msec, and turning on or turning off time is regulated to 500musec to 1msec. By the means mentioned above, any defective welding which might be caused due to electric discharge developing within the electron gun 2 can be prevented.
