Title: Driving circuit for display device
Inventor: TSUTSUI YUSUKE
IPC: G09G3/20
Filed: 1998-03-31
Granted: 2001-01-11
Abstract: A driving circuit for a display device such as a liquid crystal display comprises a signal waveform correcting circuit for highlighting a rising edge and/or a falling edge of a waveform for a unit pixel period of an input pixel signal to correct a waveform of an output pixel signal, the signal waveform correcting circuit including a delay circuit for delaying the input pixel signal, a difference calculating circuit for calculating a difference between the input pixel signal and a delay signal of the input pixel signal output from the delay circuit, and a correction signal generator for generating a correction signal on the basis of a difference signal sent from the difference calculating circuit. For example, the correction signal generator changes an amplitude of the difference signal sent from the difference calculating circuit on the basis of the amplitude to generate a correction signal, and adds the correction signal to the input pixel signal to generate a corrected pixel signal. The correction signal may be generated by amplifying or attenuating an amplitude of the input pixel signal according to the amplitude of the difference signal. Furthermore, the correction signal is generated on the basis of the difference signal and the input pixel signal, switches the correction signal and the input pixel signal in a predetermined timing to generate a corrected pixel signal, thereby driving a display pixel. When the correction signal is generated, a correction quantity can be determined in cosideration of a position of the display pixel in a display section. A distortion is easily generated in rising and falling edge portions of a waveform of a pixel signal for driving each display pixel signal. Therefore, a signal in an edge region is delayed to obtain a difference and to perform correction according to the difference. With a simple structure, consequently, a signal having a waveform which is closer to a waveform of an original pixel signal can be sent to the display pixel.

Title: Method and apparatus for controlling signal power in a communication system
Inventor: CHEN TAO
IPC: H04B7/26
Filed: 1998-09-28
Granted: 2000-10-01
Abstract: A method and apparatus for controlling signal power in a communication system provides improved power control when changing the rate at which data is sent between a transmitter (2) and a receiver (4). When data arrives at the transmitter (2) for transmission at a high rate, power control feedback is changed from a slow mode (with a low bandwidth feedback channel) to a fast mode (with a high bandwidth feedback channel). This control changes even before the data is transmitted at the high rate. Once the power level is accurately estimated for data transmission at the high rate, the data transmission begins at the high rate.

Title: Sputtering method
Inventor: YOU WEN-CHIAN
IPC: H01L21/203
Filed: 1998-09-03
Granted: 2000-04-01
Abstract: A sputtering method comprises performing a plurality of sputtering processes with a wafer stage having a plurality of wafer claws. When performing each of the sputtering processes, the wafer is grabbed by one of the wafer claws of the wafer stage. Each sputtering process uses one wafer claw which is different from other wafer claw which is used in other sputtering process. Different wafer claw grabs different position of the wafer during performing the sputtering process. Because different sputtering process uses different wafer claw to grab different position of the wafer, the wafer can be sputtered completely and the peeling contamination can be prevented. The yield and cost reduction can also be improved.

Title: Ejector pin with pressure sensor
Inventor: KAWASAKI HIROAKI
IPC: G01L9/00
Filed: 1998-09-09
Granted: 2001-03-21
Abstract: The present invention is to provide an ejector pin with pressure sensor. The ejector pin 24 has a bar-shaped portion 25 for ejecting a mold plastic product, and a sleeve portion 26 slidably receiving the bar-shaped portion 25. The front end of the bar-shaped portion 25 is adjacent to a cavity from an opening 28 of the front end of a guide portion 27. The section portion 29 on the rear end of the sleeve portion 26 has a receiving chamber 30. Inside of the receiving chamber 30, a U-shaped distortion portion 33 is provided and fixed on the base end of the bar-shaped portion 25. The bottom of the beam portion 36 of the distortion portion 33 is provided with a deformation sensor 34. Only the front end surface of the bar-shape portion 25 plays a part of pressure detection. When the resin pressure is applied on the front end of the bar-shaped portion 25 to make the bar-shaped portion 25 be subjected to a downward load, the beam portion 36 will be bent, and the deformation sensor 34 outputs a signal to calculate the pressure. If a plurality of sleeve portions having different outer diameters are prepared according to different uses, the thickness of the ejector pin can be set arbitrarily according to the use condition. Thus, even the diameter of the ejector pin is changed, the sensor can still be used without having to amend the output of the sensor or changing the design for different loading.

Granted: 2002-11-01
Abstract: In order to protect copyright, an electronic watermark inserting apparatus with a simple circuit design is used to insert or embed electronic watermarking information into still or moving image data. In the electronic watermark inserting apparatus, image data is converted into digital image data by an input circuit, the converted data is divided into plural pixel blocks on a screen by a block dividing unit, and the divided data is filtered by a BPF filter. Therefore, the frequency characteristic of the image data is measured for every block by a spectrum measuring-unit while the image data is kept in a temporal region. The magnified range of the input image data for each block is measured to determine a mixing ratio of the image data to electronic watermarking information for each block based on the intensity or the change of the amplitude measured for each block. According to the obtained ratio, an electronic watermark mixing-unit inserts an electronic watermark into the image data. The invention eliminates the needs of discrete cosine conversion and the inverse discrete cosine conversion. Therefore, the circuit of electronic watermark inserting apparatus is simplified and its circuit scale is reduced.
