Title: Single crystal pulling method and single crystal pulling device
Inventor: FUJIWARA HIDEKI
IPC: C30B15/30
Filed: 1997-08-28
Granted: 2003-07-11
Abstract: In a conventional method of pulling a large-sized single crystal, an expanded portion and a contracted portion are formed on the lower side of a neck, and the contracted portion is engaged with the single crystal, which is then pulled. During the formation of the contracted portion, the diameter thereof is reduced sharply in a usual case. Even when the diameter of this portion is controlled by using an optical measuring means, a fusion ring on the contracted portion which is hidden behind the expanded portion cannot be observed, so that it is difficult to control the diameter of the crystal. A single crystal pulling apparatus used in this method has a complicated structure and is liable to get out of order at high temperature. According to the present invention, a contracted portion is formed under the condition where the diameter thereof can be measured constantly with an optical measuring means. This method uses a single crystal pulling apparatus which is provided with a pressing means which constitutes a single crystal retaining means, and which is adapted to move a locking portion engaged with a contracted portion of the crystal from a standby position to a contracted portion engaging position.

Filed: 1997-10-16
Granted: 1998-06-11
Abstract: A phonetic detecting method, it is used to receive enhanced digital signal and judge whether it is a phonetic signal or not. It includes: - Receive enhanced digital signal. - Divide the enhanced digital signal into several time-frame signals. - Calculate amplitude-reference value corresponding to enhanced digital signal inside time-frame signal. And the amplitude-reference value represents the amplitude size of enhanced digital signal. - Calculate the sum of same amplitude referencing value in time frame, to get maximum value. The maximum value is the maximum amplitude-reference value of same amplitude-reference value in time frame. - Sequentially compare those maximum-values with background noise threshold value, and judge those maximum-values are bigger than background noise threshold value or not. In which, when those maximum-values are bigger than background noise threshold value, the enhanced digital signal is the phonetic signal, and output the starting/ending detecting signal with enable mode, and representing to detect a starting point. If those maximum-values are less than background noise threshold value, then the enhanced digital signal is not the phonetic signal.

Title: Memory device with fast write recovery and related write recovery method
Inventor: PANTELAKIS DIMITRIS C
IPC: G11C7/12
Filed: 1997-12-16
Granted: 2000-10-11
Abstract: A memory (10) such as a current sensing static random access memory (SRAM) achieves fast write recovery through bit line loads and two additional mechanisms. First, an additional load (252) on shared data lines also becomes active to speed the write recovery process. Second, multiple columns (200, 202, 204) are connected to common data lines during write recovery so that a column written to during a write cycle may be again precharged in part by charge sharing using the charge stored in other columns. These two mechanisms allow fast write recovery with minimum column pitch and avoid the problems which would be encountered if the loads were placed on the write data line.

Title: Apparatus, method and computer program product for protecting copyright data within a computer system
Inventor: CIACELLI MARK LOUIS
IPC: H04N21/4408
Filed: 1998-03-26
Granted: 2000-02-11
Abstract: Apparatus, method and computer program product are provided for digitally processing an encrypted data stream scrambled, for example, according to content scrambling system (CSS) technology. This digital processing insured against communication of clear data within the computer system from a central processing unit (CPU) to any accessible structure, such as memory or a system bus. Descrambling of the (CSS) scrambled data stream occurs within a module executing on the CPU, which is followed by re-encryption of the data prior to transfer from the CPU. By so processing the data, integrity of copyrighted material is maintained, while allowing for software descrambling of the CSS encrypted data stream. Various techniques for establishing the encryption/decryption algorithm pair employed are described. Decryption of the re-encrypted data can occur at a receiving software module and/or a receiving hardware device, such as a decoder.

Inventor: CHEN SHIUE-JUNG
IPC: G01B11/06
Filed: 1998-10-12
Granted: 2000-11-11
Abstract: A method of in-situ material layer thickness detection, in which the thickness of material will decrease along with the process time, and by emitting an incident laser to material layer to get reflecting laser, and dividing the integration curve of reflecting laser strength over time by the product of differential curve and time (which is thus called I-DT transformation), therefore to get a transformation curve with cotangent characteristic to time. Because the transformation function has the characteristics of peek values being distinct, the positive and negative value of function representing the strength curve slope and curves between peek values being flat, it can provide a clear and steady rule to find the analytical endpoint of CMP process, and solve the problem encountered during detecting endpoint before.

Title: Tilt cylinder controlling apparatus and method for industrial vehicle
Inventor: KAMIYA TOSHIKAZU
IPC: B66F9/22
Filed: 1998-12-07
Granted: 2002-08-11
Abstract: An apparatus for controlling tilt cylinders (9) that tilt a mast (3) of a forklift (1) is disclosed. A tilt control valve (22) controls the flow of hydraulic oil to actuate the tilt cylinders. The tilt control valve is switched between two positions by a tilt lever (13). When at one position, the tilt control valve stops flow of oil to the tilt cylinders (9) thereby prohibiting tilting of the mast. When at the other position, the tilt control valve permits oil flow to the tilt cylinder thereby allowing tilting of the mast. A control valve (59) is located between the tilt cylinder and the tilt control valve. A seat switch (10a) detects whether the operator is on a seat. A CPU (49) permits the operator to continue to operate the tilt cylinders to tilt the mast when out of the set for a brief period. However, after brief period, the CPU closes the control valve (59) to prevent movement of the mast unless the operator has returned to the seat. When the mast reaches a predetermined maximum acceptable tilt angle, the CPU also closes the control valve thereby prohibiting motion of the tilt cylinders.

Title: Disk loading device
Inventor: HUANG AN-YING
IPC: G11B17/056
Filed: 1999-04-03
Granted: 2001-03-01
Abstract: The present invention proposes a disk loading mechanism that consists of a vertical protection plate and a push block. The vertical protection plate can be used for holding an ordinary compact disk so that the disk will not topple during loading when the disk drive is placed vertically. The push block is used for pushing against a cassette disk. On the other hand, when the disk drive is placed vertically, since the push block pushes against the cassette, the cassette will not topple during loading. By means of the present mechanism, loading of a compact disk or a cassette disk will not be affected regardless the disk drive is placed horizontally or vertically. Furthermore, the disk loading mechanism can also use a prestressed arm to accomplish such purpose.

Title: DC offset compensation for zero if quadrature demodulator
Inventor: MOHINDRA RISHI
IPC: H04L27/14
Filed: 1999-06-28
Granted: 2001-12-21
Abstract: The present invention provides dc offset compensation circuit (800) for a zero IF FM quadrature demodulator in an AMPS cellular mobile telephone system. A frequency offset is introduced to remove modulation inherent dc components from supervisory audio tones and Manchester codes from a modulated signal. The local oscillator (608) is operated at a frequency that is slightly different, e.g. 5kHz from a frequency which would mix down the intermediate frequency signal to zero. A dc offset is produced with a control loop to eliminate fixed dc components caused by leakage from a local oscillator (608). After a given time, the control loop may be frozen and the frequency offset of the local oscillator (608) can be removed.
