Title: Electrical resistance heater for crystal growing apparatus
Inventor: SCHRENKER RICHARD G
IPC: C30B15/14
Filed: 1999-05-31
Granted: 2001-07-01
Abstract: An electrical resistance heater of the present invention for use in a crystal puller used for growing monocrystalline silicon ingots according to the Czochralski method comprises a heating element sized and shaped for disposition in the housing of the crystal puller around the crucible for applying heat to the crucible and silicon therein. The heating element includes heating segments connected together in an electric circuit. The segments have upper and lower sections and are arranged relative to each other so that when disposed around the crucible containing molten silicon the upper sections are disposed generally above a horizontal plane including the surface of the molten silicon and the lower sections are disposed generally below the horizontal plane. The upper sections are constructed to generate more heating power than the lower sections thereby to reduce a temperature gradient between the molten silicon at its surface and the ingot just above the surface of the molten silicon. The upper sections have a thickness substantially equal to the thickness of the lower sections and have a width substantially less than the width of the lower sections. The cross-sectional area of the upper sections is everywhere less than the cross-sectional area of the lower sections.

Title: Method for making manganese oxide-based material
Inventor: COOWAR FAZLIL
IPC: C01G45/00
Filed: 1999-09-08
Granted: 2002-09-01
Abstract: An oxide LiMnO2 which has a layered monoclinic structure, and in which a minor part of the manganese may be replaced by another transition metal, is made by a two-stage process. Firstly NaXO2 with a layered structure of the Α-NaFeO2-type is made by reacting stoichiometric amounts of a sodium salt and a salt of the metal X in solution so as to form a precipitate, drying and heat treating the precipitate at a temperature between 650 and 720 DEG C in air, and then rapidly cooling the precipitate to room temperature in air. Then the NaXO2 is subjected to ion exchange with a lithium salt in solution in a non-alcoholic solvent at a temperature between about 140 and 210 DEG C. The resulting lithium manganese oxide can be used as the cathode material in a rechargeable lithium cell.

Title: Manufacture method for self-aligned borderless contacts on shallow trench isolation
Inventor: WU HUA-SHU
IPC: H01L21/02
Filed: 1999-11-16
Granted: 2001-09-01
Abstract: This invention provides a method to produce self-aligned borderless contacts on shallow trench isolation for semiconductor manufacture processes. Such a method is performed with simple processes while requiring no new materials. A wider process window can be obtained due to forming high selectivity of the self-aligned silicon nitride to chemical solution used for wet cleaning, thereby preventing the formation of breakdown voltage of the transistor on the top edge of the shallow trench isolation from electric field concentration and also avoiding low yield or poor reliability of the transistors at the threshold voltage caused by leakage current. The degree of integration on wafers and the density of device can be increased because the formation of borderless contacts reduces the wafer surface occupied by contact alignment.

Granted: 2002-07-01
Abstract: There is described an FM receiver (29) including: an antenna (2) able to receive a high frequency signal from a transmitter; a high frequency stage (3); an oscillator (5); a mixer unit (30) able to provide a signal (S6) at an intermediate frequency (tip); an FM demodulation stage (8); and an automatic frequency control stage (36) able to control the oscillator, so as to keep said intermediate frequency (fIF) of said signal (S6) constant. This receiver further includes a locked loop (32) arranged to enslave said intermediate frequency (fIF) from a pilot frequency (fp) present in the demodulated signal. One advantage of such a locked loop is that the intermediate frequency is enslaved so that the aliasing phenomenon does not prevent demodulation of the signals containing the RDS data.

Title: Method of controlling an ink agitator of a wet type electrophotography printer
Inventor: KIM JONG-WOO
IPC: G03G15/10
Filed: 2000-12-04
Granted: 2002-11-11
Abstract: A method of controlling an ink agitator of a wet-type electrophotography printer. The method includes the steps of checking and determining the extent of the printer non-usage time during the printer initialization operation, selecting the driving time of the ink agitator according to the extent of the non-usage time from the first step, and driving the ink agitator according to the ink agitator driving time selected at the second step. Here, the printer non-usage time determining step determines whether the non-usage time is a first selection time, a second selection time, or a third selection time and sets a first, second and third ink agitator driving time according to the length of the non-usage time. Accordingly, because the ink agitator is driven according to the non-usage time of the printer, it is able to completely dissolve deposition and lumps of ink even when the non-usage time is substantially long. Also, in cases where the ink agitator driving time is longer than the time taken to completely disperse the developer within the circulation tanks, when dispersion of the developer within the circulation tanks is completed, the printer is able to perform printing operations and the ink agitator is continually driven throughout the set time. Therefore, uniform initialization operation time can be maintained regardless of the non-usage time of the printer.
