Title: High frequency induction coupling plasma mass spectrometer
Inventor: YAMANAKA KAZUO
IPC: H01J49/26
Filed: 1991-03-01
Abstract: PURPOSE:To simplify a mechanism and to prevent diverging of ions in the vicinity of a gate valve so as to enhance detection sensitivity by providing an ion lens within a gate valve, and using in common to all components the gate of a shifting mechanism for shifting the lens. CONSTITUTION:When a gate valve 21 is open a gate is put in a body from a valve opening 28 and at the same time an ion lens is installed near the opening 28. Also voltage is applied to the ion lens from a variable voltage power source. When the valve 21 is open the power source is turned off to set the voltage applied to the lens at zero and thereby the gate is shifted from within the body to the position of the opening 28 and also the lens is shifted from the position of the opening 28 into the body. The ion lens is thus made to exist in all of a fore-chamber 11, the valve 21 and a center chamber 13 by opening and closing of the valve 21 and also the intervals among the lenses are kept narrow. Thereby diverging of ions in the vicinity of the valve is prevented so as to enhance detection sensitivity.

Filed: 1981-03-16
Abstract: PURPOSE:To surely protect the magnetic bubble memory element from static electricity caused by human bodies, etc., and to completely eliminate risks of breaking of the memory element, by improving the connector of the magnetic bubble cassette. CONSTITUTION:The 4 in the diagram represents a wiring pattern of a signal line of a magnetic bubble memory, and the 5a clip type connector.
