Title: A protection circuit for a cathode ray tube
Inventor: GEORGE JOHN BARRETT
IPC: H04N3/20
Filed: 1991-04-25
Abstract: A circuit for protecting a cathode ray tube (10) screen from damage by an electron beam includes a semiconductor switch device 106 having an input coupled to a signal HOR related to a deflection signal for the electron beam. The switch device 106 is coupled to a voltage supply V1 and the circuit further includes a charge storage device 110 coupled to the switch device 106 and further coupled to a control grid G1 of the cathode ray tube 10. The charge storage device 110 is charged through the switch device 106 by the voltage supply V1 when the signal HQR related to a deflection signal is present at a control input of the switch device 106. The switch device 106 decouples the supply voltage V1 from the charge storage device 110 when the signal HOR related to a deflection signal is not present and places a negative blanking voltage developed on the charge storage device 110 across the control grid G1 when the signal HOR related to a deflection signal is not present to cut-off beam current i BEAM in the cathode ray tube 10. <IMAGE>

Patent GB-2281437-A (GB)
Title: Metal vapor lasers
Inventor: SAITO HIROSHI
IPC: H01S3/227
Filed: 1994-08-15
Abstract: To a laser medium comprising vapor of metal atoms A is added vapor of metal atoms B such that the difference  DELTA E(B) between the energy value E1(B) at the upper laser level and the energy value at the lower laser level E2(B) of atoms B as the metastable state after laser transition or fluorescent transition is substantially equal to the energy level E2(A) of the metal atoms A at the lower laser level relative to the ground level E0(A). Secondary collision of the metal atoms A in the E2(A) state and the metal atoms B in the E2(B) state with one another causes energy transition, whereby the metal atoms A excite the metal atoms B to the resonant excitation level E1(B) and undergo transition to a ground level E0(A). Alternatively or in addition, the energy level difference  DELTA E(A) of atoms A may be substantially equal to energy level E2(B) of atoms B, with similar results. Consequently, the excitation lifetime at the lower laser level in the laser transition is reduced to extend the inverse population time and also the laser output pulse width so as to increase the laser conversion efficiency. <IMAGE>
