IPC: H04N5/91
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To record and reproduce a teletext signal by using a VHS video recorder. SOLUTION: Teletext data are converted into a multi-value level code (4-value) at a low data rate (a half). In the case of recording, an encoder 7 receives the teletext data from a RAM 6, the data are coded into a multi-value level code at a low data rate, and fed to a conventional luminance processor 10 of a VCR. In the case of reproduction, the multi-value level code is reproduced and fed to a decoder 13, where the code is converted into a binary code at a standard teletext data rate. It is stored in the RAM 6 and read by a teletext decoder 14, in which a clock run-in and framing code is added. A multiplexer 15 multiplexes the result with a CVBS and the result is fed to an output 16.

Abstract: PURPOSE:To prevent noise occurrence in forming the contact to be coarse by providing a water containing layer on the appropriate position of the die surface of an upper die, and placing the layer into contact with the surface of foaming urethane during molding a pad. CONSTITUTION:A trim cover is set in a die-open state on the die surface 1a of a lower die 1 and foaming urethane liquid is poured in a certain quantity into the lower die, and as an upper die 2 is die-clamped, the foaming urethane liquid is formed and cured while being filled into the cavity formed between the upper and lower die. At this time, the part in contact with the general part of die surface 2a of a molded pad 10 becomes a compact and smooth skin layer 10a in its surface. The part in contact with porous silicon 4 comes into contact with the water contained therein, and the surface becomes a coarse surface 10b. In a state wherein the obtained pad 10 and the trim cover 14 are fabricated to the frame 12, the contacting part of the pad 10 to the frame 12 becomes the coarse surface 10b. By the coarse surface, the noise occurred through the relative slip by the coarse surface can be prevented.

CONSTITUTION:Between power supply and ground, an n-channel MOST 11 and a p-channel MOST 12 whose size is smaller than an n-channel MOST 3 and a p-channel MOST 2 are provided in series. An input signal connection terminal 6 is connected in common to a gate of the n-MOST 11 and the p- MOST 12 and a connecting point N3 between the source of the nMOST 11 and the source of pMOST 12 connects to an output section N2 of an output buffer 1. In such a case, the potential of an output signal OUT is monitored to turn on either of the pMOST 2 and the nMOST 3 based on H, L level of the output signal OUT. The ON/OFF control of the pMOST 2 and the nMOST 3 is implemented by using a NAND gate 7 and a NOR gate 8. Thus, the possibility of simultaneous ON of the pMOST 2 and the nMOST 3, that is, the possibility of flow of through-current to the output buffer 1 is made zero.

Title: Manufacture of insulating film for isolation of element in semiconductor device
Inventor: KAMISAKA WATARU
IPC: H01L21/316
Filed: 1989-03-14
Abstract: PURPOSE:To enable formation of an element isolation region in uniform dimensions by forming a side wall by making a high-temperature silicon oxide film grow by a chemical vapor deposition method after patterning of a first silicon nitride film and by making a second silicon nitride film thereafter. CONSTITUTION:After formation of a first silicon nitride film 8 serving as an oxidation-resistant masking material, a high-temperature silicon oxide film 9 is made to grow by a chemical vapor growth method in the sidewall part of the first silicon nitride film 8 before a second silicon nitride film 10 is formed as a side wall therein. Therefore, the high-temperature silicon oxide film 9 formed by the chemical vapor deposition method shows a high etching selection ratio at the time of anisotropic dry etching for forming the side wall of the second silicon nitride film 10, and it is left without being etched nearly at all. Accordingly, the first silicon nitride film located under the high-temperature silicon oxide film 9 is not etched at all and acts as the oxidation-resistant masking material with a uniform initial film thickness at the time of its growth left as it is. Thereby the expansion of an element isolation region in the lateral direction is made uniform.
