Title: Charged particle beam apparatus
Inventor: TAKASHIMA SUSUMU
IPC: H01J37/21
Filed: 1990-10-18
Abstract: A charged particle beam apparatus, eg. a scanning electron microscope capable of adjusting the convergence angle of the beam probe independent of the beam current at the specimen, comprises a source 11 of charged particles, a first condenser lens 13, a second condenser lens 14, an objective lens 15, an aperture 21, and an auxiliary condenser lens 20. The lenses 13, 14, 15 act to sharply focus the beam to form an electron probe impinging on the specimen 16. The auxiliary lens 20 controls the convergence angle  alpha  of the probe, and the beam path from the aperture 21 to the specimen 17 is wide enough to prevent the beam current at the specimen from varying if the strength of the auxiliary lens and the strength of the objective lens are varied. Preferably auxiliary lens 20 is electrostatic. To set up the apparatus there is determined (i) a range of strengths of lenses 13, 14 required to set a range of beam currents over a range of accelerating voltages which are stored in memory 28; (ii) a range of strengths of auxiliary lens 20 which give an optimum convergence angle for every possible set of accelerating voltage and beam current, which are stored in memory 29; and (iii) the strengths of the objective lens 15 needed to focus the beam on the specimen for every possible strength of the auxiliary lens 20, which are stored in memory 30. The apparatus is automatically set up by the control arrangement when the accelerating voltage and the beam current are specified. <IMAGE>

Title: Data output buffer circuit with bootstrap
Inventor: LEE JANG-KYU
IPC: H03K19/094
Filed: 1991-01-21
Abstract: A data output buffer circuit comprises NMOS transistors NM1 and NM2 connected in series between the power rails Vcc1 (Vcc1 may be 4V) and Vss of a memory; in order to ensure that NM1 fully switches on in response to data HIGH it is driven via bootstrap circuit 20, which receives a boosted supply voltage Vcc2 higher than Vcc1 provided by supply voltage converter 30. The drive voltage to NM1 is a constant voltage above Vcc1 regardless of fluctuations in the supply Vcc1 so that ringing due to excessive drive voltage may be avoided whilst improving noise margins. <IMAGE>

Title: Controlling the cross-linking reaction in a well fracturing fluid
Inventor: DAWSON JEFFREY C
IPC: C09K8/68
Filed: 1991-03-16
Abstract: A complexor and method of use are shown for providing controlled delay of the cross-linking reaction in an aqueous well fracturing fluid. A base fluid is first prepared by blending together an aqueous fluid and a hydratable polymer which is capable of gelling in the presence of borate ions. The complexor is prepared by mixing a cross-linking additive capable of furnishing borate ions in solution with a delay additive. The delay additive is effective, within a selected pH range, to chemically bond with both boric acid and the borate ions produced by the cross-linking additive to thereby limit the number of borate ions initially available in solution for subsequent cross-linking of the hydratable polysaccharide. The subsequent rate of cross-linking of the polysaccharide can be controlled by adjusting the pH of the complexor solution.

Title: A valve-controlled positive-displacement pump
Inventor: STOLPP DIETER
IPC: F04B1/107
Filed: 1992-11-06
Abstract: A positive displacement pump comprising pistons (11) reciprocating in radial bores (10) is controlled by holding open the inlet valves which normally let fluid pass through suction bores (12) in the pistons into the working chambers (15). The pistons are reciprocated by an eccentric (3) against the bias of springs (13). During pumping the radially inwardly extending stems of the inlet valves are free to move since they are in alignment with a circumferential groove (5) in the surface of a sleeve (4) around the eccentric. By arranging for the sleeve to be axially displaced, the stems come into contact with the peripheral surface of the sleeve with the result that the inlet valves are unable to close and pumping is discontinued. In an alternative embodiment the pistons are disposed in different planes, the valves in some planes being rendered inoperative while others remain operative. By, for example, reducing the lengths of some of the valve stems it is possible to reduce the capacity by a set proportion without reducing it to zero. <IMAGE>

Title: Correcting image blur due to camera movement
Inventor: NISHIDA YOSHIHIRO
IPC: H04N5/232
Filed: 1994-02-16
Abstract: In a hand-held video camera lens barrel 1 is pivotable with respect to supporting body 3. Image blur induced by shaking the camera is corrected by driving the lens barrel 1 to compensate for the measured angular displacement and velocity of the lens barrel. Video signals from imager 2 (eg CCD) are fed to motion vector detecting circuit 12; from this motion detected in the image is used to determine the angular velocity of the lens barrel by angular velocity calculator 13 taking zoom into account. The angular displacement of the lens barrel is determined by sensor 9, and together with the angular velocity is used to drive 15 actuator 5. By moving only the lens barrel relative to supporting body 3, the weight of the image blur correcting means is reduced and made suitable for use in a hand-held video camera. <IMAGE>
