Title: MALDI time-of-flight mass spectrometers
Inventor: FRANZEN JOCHEN
IPC: H01J49/40
Filed: 1997-08-20
Abstract: Exact mass determination of analyte tons in time-of-flight mass spectrometers is achieved using an ionization of analyte substances on sample supports by matrix-assisted laser desorption (MALDI), and time-delayed ion acceleration in the field between the sample support 1 and an intermediate acceleration electrode 2. An unknown change in the distance of the sample support 1 from the intermediate acceleration electrode 2 can be compensated for by a coupled change of both total accelerating voltage U s  and partial acceleration voltage V S  between sample support and intermediate electrode, so as to cause the time of flight of ions from a reference substance to agree with value given by a calibration mass scale. The partial accelerating voltage V S  and the total accelerating voltage U S  are controlled through a common control parameter p and an instrumental constant C 1  according to equations V S  = V C  x (1 + p) and U S  = U C  Î (1 + c 1  Î p) where V C  and U C  are accelerating voltages provided by calibration of the mass scale. Oligomeric ions from the matrix of the MALDI method serve very well as reference ions. Furthermore, if the range of optimum focus is shifted by a change in the time delay, the calibrated mass scale can be kept valid for all masses through a simultaneous change of the accelerating voltage.

Title: Vaporizer in CVD apparatus supplied with additional solvent
Inventor: YU YONG SIK
IPC: C30B35/00
Filed: 1997-08-28
Abstract: A metal organic chemical vapor deposition apparatus comprises a source ampule, a liquid micro-pump 20, a vaporizer 30 equipped with a solvent supply means 100, and a reactor 70. A reactant dissolved in a solvent in the source ampule is transferred to the vaporizer by the liquid micro-pump. A sufficient amount of the solvent is additionally fed to the vaporizer by the solvent supply means, concurrently with the transfer, and vaporized along with the reactants. After being vaporized in the vaporizer, the reactant is injected to the reactor by carrier gas and deposited on a semiconductor substrate to form a high dielectric thin film. By virtue of the additional supplied solvent, the recondensation of the reactant in the vaporizer, which is attributed to the separation of the solvent from the reactant, can be prevented in the vaporizer and in the transfer line between the vaporizer and the reactor. In addition, the residues of the reactant, which may result from the separation, can be washed off by providing the solvent through the supply means to the vaporizer. The solvent supply means comprises a solvent ampule 40 and a pump 50. Films such as BaSrTiO 3 and SrTiO 3 are formed using Ba(di-piraloyl methanate) 2 , Sr(di-pivaloyl methanate) 2 and Ti(di-piraloyl methante) 2 . The additional solvent may be isopropyl amine.

Title: Chewable device for cleaning teeth
Inventor: KEAVENEY ENDA
IPC: A46B9/04
Filed: 1999-03-17
Abstract: A device is provided for cleaning teeth. The device comprises a resilient element 1 which is adapted to deform from an initial condition to a final condition. The resilient element carries a plurality of bristles which are directed upwardly, and a plurality of bristles which are directed downwardly when the element is in the initial condition. As the resilient element is deformed, for example when being gripped between upper teeth and lower teeth, the outermost bristles of those directed upwardly, on either side of the resilient element, become directed more inwardly, with a similar effect being observed with the bristles initially extending downwardly. The bristles thus come into contact with the sides of the teeth to effect a cleaning action.

Title: A magnetic flow meter with two channels
Inventor: DAMES ANDREW NICHOLAS
IPC: G01F1/58
Filed: 1999-06-17
Abstract: A magnetic flow meter includes a cylindrical vessel 34 within which electrodes 42 are placed directly opposite each other about a magnetically permeable core to define two flow channels. A common magnetic field is applied across both flow channels. The magnetic flow meter is used in conjunction with a controller (figure 6) which monitors amplitude modulated signals representative of applied magnetic field and induced electric field. These amplitude modulated signals are passed to Sigma-Delta modulators, which directly digitise the amplitude modulated AC signals into digital pulses. The controller is capable of monitoring reverse flow through the meter and storing results until forward flow resumes. Moreover, the controller generates a driving signal for coils (64, figure 1) which generate a magnetic field, the coils being operated in conjunction with a capacitor which causes resonance and reduces power consumption.
