Title: Combustible material igniter
Inventor: KONRATSUTO ZERUBUEEGERU
IPC: F23Q2/28
Filed: 1989-06-16
Abstract: PURPOSE: To direct a thin flame easily in any direction with no risk of burn by inclining the direction of inlet opening-outlet opening of a combustion chamber with respect to the body direction. CONSTITUTION: A nozzle is directed in the axial direction of a Venturi-shaped hole 40 made in a member 41 including a tubular chamber 42 having axis inclining against that of a Venturi so that combustion air can be fed easily to the Venturi-shaped hole 40. The nozzle 11 and the Venturi define an air-gas mixer making some angle to the direction of inlet opening-outlet opening of a combustion chamber 7. A turbulence is induced in the chamber 42 by the angle between the axis of the chamber 42 and the axis of the opening 40 to produce an extremely homogeneous air-gas mixture. Combustion reaction is thereby sustained in the chamber and the possibility that a flame leaks from the chamber to be extinguished by wind is eliminated perfectly.

IPC: H01J29/48
Filed: 1984-07-27
Abstract: PURPOSE:To prevent a false signal due to a return beam by juxtaposing the central cylinder projected in the direction of the target on the surface of the second grid provided with a beam aperture and therearound conical corrugations inclined to an axis of an electron gun while roughing their surface. CONSTITUTION:The central cylinder 7 projected in the direction of the target is arranged on the surface of the second grid 5 provided with a beam aperture 6 while arranging therearound the trumpet-shaped corrugations 7' and 7'' in a ripple state. The corrugations have a certain angle to the axis of an electron gun while their surface is roughed. Consequently, the return beam 11 does not return in the direction of the target after collision while being absorbed or scattered 13. Further, the reflection beam 13 scarecely has constitutional information on the corrugations even when it incides again into the target because of variety of reflection orbits. According to said constitution, the false signal due to the return beam can be extremely reduced thus obtaining a pick-up tube of high quality.
