Patent GB-2300295-A (GB)
Title: Transporting ions in a capillary
Inventor: FRANZEN JOCHEN
IPC: H01J49/04
Filed: 1996-04-25
Abstract: During the transport of ions in a gas flow in a capillary, e.g. to a mass spectrometer, the ions must not touch the wall of the capillary or else they will be discharged upon collision with the wall. The invention consists of making the capillary 23 of resistive material or providing it with an internal resistive coating 24, so keeping the ions in the gas flow free of any wall collisions by gas-dynamic focussing of the ions into the center of the gas stream. Focussing is achieved when the ions are decelerated by an electric field relative to the gas flow so that they have a lower transport velocity than the gas stream. Due to the parabolic velocity profile of the laminar gas stream, ions which are not at the center of the capillary are subjected to circumfluence by gas with different velocities at both sides, resulting in a force toward the capillary axis. This component of force is the stronger the farther the ions are away from the center axis and the more they are decelerated.

Title: Adjustable frequency synthesizer
Inventor: BALDWIN GEORGE H
IPC: H03L7/18
Filed: 1995-01-18
Abstract: A phase-locked-loop frequency synthesizer with adjustable frequency has a signal source of predetermined reference frequency of 10, 100 or 1,000 Hz, and a comparator with a first input receiving the reference frequency signal, a second input receiving a signal of divided frequency, and an output producing an output signal dependent on the difference between or equality of the reference frequency signal and the divided frequency signal. The comparator operates to adjust the frequency of the increased frequency signal produced by the oscillator in such a manner as to equalize the frequencies of the divided frequency signal and the reference frequency signal. The synthesizer also has a voltage controlled oscillator controlled by the comparator output signal to produce an output signal of increased frequency. A first frequency divider divides the frequency of a signal derived from the increased frequency output signal to produce a first divided frequency signal at an output, a first blanking circuit operates to remove a predetermined number of pulses per second from the increased frequency output signal to produce the derived signal whose frequency is divided by the first frequency divider, and a first adjustable selector is provided for adjustably selecting the number of pulses per second to be removed by the first blanking circuit. A second frequency divider divides the frequency of a signal derived from the first divided frequency signal to produce a second divided frequency signal, a second blanking circuit operates to remove a predetermined number of pulses per second from the first divided frequency signal to produce the derived signal whose frequency is divided by the second frequency divider, and a second adjustable selector is provided for adjustably selecting the number of pulses to be removed by the second blanking circuit.

Title: Tin film actuated mirror
Inventor: PARK MYUNG-HYUN
IPC: G02B26/08
Filed: 1996-08-21
Abstract: In making a thin film actuated mirror an elastic layer is formed of a material such as silicon nitride which is divided vertically into two portions differing in stoichiometry. The elastic layer is laid down by a CVD method and the stoichiometry and therefore the stress built up in the layer is controlled by controlling the composition ratio of the source gas. The formation of the elastic layer is preceded by forming a sacrificial layer and succeeded by forming an actuating structure on the elastic layer.

Title: Shaped-beam laser texturing of magnetic media
Inventor: WEI BO
IPC: B23K26/06
Filed: 1997-05-13
Abstract: Magnetic data storage disks (38), particularly along dedicated transducing head contact regions, are laser textured according to a process in which beam shaping optical components impart an elliptical or elongated cross-section to the laser beam. Consequently, individual texturing features such as rims (88) and nodules are elliptical or elongate, with more gradual height gradients in directions parallel to their major axes. The texturing features are oriented with respect to the direction of transducing head acceleration and deceleration. Texturing features are formed in a variety of patterns, including patterns with adjacent features contacting one another. Features may be formed with substantially different slopes on opposite sides of a maximum height region (90).
