The first amplifying circuit(30) amplifies the output from the first integral circuit(20) according to an user's control.  The electronic quadruple lens(40) regulates the vertical focus of the electron beam by the output from the first amplifying circuit(30).  Thereby, the vertical focus of the electron beam can be automatically and accurately regulated.

Title: Structure and manufacturing method of single transistor memory device
Inventor: HWANG HYUN-SANG
IPC: H01L27/108
Filed: 1992-10-22
Granted: 1996-04-23
Abstract: The single transistor memory device is fabricated by forming the gate insulating layer(10) with dangling bond structure on the substrate(1), forming a conductive layer on the gate insulating layer(10), patterning the conductive layer and gate insulating layer to form the gate(2), forming the impurity-doped regions(3) on the substrate of the sides of the gate(2), forming a first insulating layer on the overall surface of the substrate(1), selectively removing the portion of the first insulating layer placed on one of the impurity-doped regions(3) to form the bit line contact, and forming the bit line in the contact.

Title: Isomerization of epoxyalkenes to 2,5-dihydrofurans and catalysts compositons useful thereof
Inventor: MONNIER JOHN R
IPC: B01J23/06
Filed: 1991-03-07
Granted: 1998-12-01
Abstract: Disclosed are processes for the isomerization of epoxyalkenes to dihydrofurans by contacting an epoxyalkene with a catalyst comprising a quaternary organic onium iodide compounds, optionally deposited on a non-acidic support and/or in combination with a Lewis acid co-catalyst. The catalyst may comprise a supported catalyst, an unsupported catalyst or a solution of the catalytically-active components in an inert, organic solvent.
