摘要:
A molding material for use with carbon dioxde, which comprises chlorinated polyethylene having a chlorine content of 25–47% by weight or a blend of chlorinated polyethylene with vinyl chloride-based resin, can be used as a suitable material for sealing materials in carbon dioxide-contacting apparatuses using carbon dioxide as a refrigerant. Addition of a specific silane coupling agent to the molding material can effectively prevent vulcanization moldings from blister generation.
摘要:
A current mode A/D converter for reducing current consumption while enhancing resolution. The A/D converter includes a V/I conversion circuit for sampling and converting an input voltage to a current, an I/V conversion circuit for converting the current supplied from the V/I conversion circuit to a comparison voltage, a comparator for comparing the current based on the comparison voltage and a reference current, and an encoder for generating a digital output signal based on the output signal of the comparator.

In a liquid crystal display apparatus having a backlight disposed behind a liquid crystal display panel 10, the liquid crystal display panel 10 has first and second substrates 11 and 21 disposed to face each other. The second substrate 21 has a common electrode 20 laid in a display area 12 thereon. The second substrate 21 further has a light-shielding inner black matrix 22 laid around the display area 12 and a light-shielding electrically insulated black matrix 22A, 22B, and 22C laid outside the inner black matrix 22 and electrically separated from the inner black matrix 22 and the common electrode 19. The liquid crystal display panel 10 is held, at the periphery thereof, by metal support frames 32 and 33.
摘要:
An enumeration method for the link rate and a pixel/audio clock rate. The method can be performed by expressing the pixel/audio clock rate and the link rate with four parameters, A, B, C, and D based upon a master frequency 23.76 GHz as 210×33×57×111 Hz, and regenerating a pixel/audio clock from the link clock.

摘要:
In a digital display device, a packet based method of driving selected pixel elements by way of associated data latches included in a column driver is disclosed. For each frame lines in a video frame, a number of video data packets are provided directly to the column driver at a link rate and each of the number of data latches are populated with appropriate video data based upon video data packets within a line period τ. Selected pixel elements are driven based upon the video data.
摘要:
Keys (e.g., decryption key, authentication key) are stored in a non-volatile memory of a display unit. The keys are retrieved in encrypted form into an integrated circuit. The integrated circuit decrypts the keys and uses the keys. As the keys are available in decrypted form only within the integrated circuit and potentially only during use, the keys may not be available to unauthorized third parties.
摘要:
Displaying the images encoded in a display signal which also contains synchronization signals and display enable (DE) signal. The DE signal indicates the time points at which the display data portion of the display signal contains active pixel data elements representing image frames. A display unit generates HDISP and VDISP signals (indicative of the active time in which active pixels and lines are respectively received) based on the DE signal. As the DE signal generally tracks (in the time domain) the active pixel data elements, the active pixel data elements forming image frames are accurately identified, and a superior image quality generally results.
摘要:
An optical fiber coupler according to the present invention comprises two optical fibers which each include a core portion serving to propagate light and a clad portion surrounding said core portion, the two optical fibers extending substantially in parallel in a same flat plane, and a melting portion in which the clad portions of the two optical fibers are fused together substantially in a line contact. Two optical fibers are arranged in parallel to permit at least parts of the clad portions to be brought into contact with each other. In this state, the two optical fibers are heated and fused mutually substantially in a line contact and are further drawn for fabrication thereof. The optical fibers are heated preferably employing an electric ceramic microheater. The two optical fibers may be same or different in structural parameters.
