Patent EP-0557641-A2 (EP)
Inventor: KO JUNG-WAN
IPC: H04N9/79
Filed: 1992-10-07
Abstract: A video recording/playback system includes in its recording electronics time-base correctors (TBC1, TBC2) both for luma signal and for color-under signal, the time-base corrector (TBC1) for luma signal being used to facilitate comb filtering and the time-base corrector (TBC2) for chroma signal being used to maintain luma/chroma tracking during recording. The video recording/playback system includes in its playback electronics time-base correctors (TBC3, TBC4) both for played-back luma signal and for played-back color-under signal, the time-base corrector (TBC3) for played-back luma signal being used to facilitate comb filtering and the time-base corrector (TBC4) for played-back chroma signal being used to maintain luma/chroma tracking during playback. With appropriate switching, the same pair of time-base correctors (TBC1,2 or TBC3,4) can be used in both the recording and the playback electronics of the video recording/playback system. A detector in the recording electronics determines when there is substantial time-base error in the video signal received for recording and conditions the comb filtering of the luma signal during recording to be carried out in just the spatial domain and not in the frame-to-frame time domain. The recording electronics includes circuitry for signaling the playback electronics, via a recorded signal, that the comb filtering of the luma signal during recording was carried out in just the spatial domain and not in the frame-to-frame time domain. The playback electronics responds to such signaling to adapt the comb filtering of the played-back luma signal to suit. Furthermore, time-base correctors are disclosed, which respond to sync signals. 
     One embodiment contains PLLs generating a chrominance carrier, as well. Another embodiment contains PLLs generating a chromatic carrier, as well. Another embodiment has different clocks for low frequency and high frequency time-base errors.

Abstract: A method for stress testing a memory array in an integrated circuit. Control circuitry selects a plurality of row lines at one time. An overvoltage suitable for stressing the cells of the array is placed on the bit lines. Because a block of cells has been selected, the overvoltage is applied to all cells of the block. The block of cells selected may be either the entire memory array or a portion of the memory array. The selected rows remain selected for the duration of the stress test. Because the overvoltage is applied directly to selected cells, the full overvoltage will be used to stress the transistor gates for the entire test period. In this manner, latent defects within the memory array can be detected.

Abstract: The invention has been newly deviced in relation to a sliding member of less wear and low coefficient of friction, particularly to a structure of a sliding surface of a sliding parts for a sliding shaft and a counter sliding bearing. 
     For the aimed purpose, the inventors have found that the surface of the sliding shaft, when provided with random irregularity of surface roughness of 0.2 to 20µm or lower (by JIS, Rz indication), has favourable performance in comparison with the conventional directional irregularity or a plain face as a mirror surface. 
     Also, a sliding surface on the bearing, when provided with two-dimensionally random irregularity of roughness defined by Rz values of 20 to 500µm or a pattern of small and independent recesses and/or protuberances of 20 µm or more in depth, can exhibit the same effect as of the above. 
     The shaft or bearing having the above structure has durability in dry and long use to be effectively applicable to precision machines, particularly, copying machines and a sliding device for use at high and low temperature housed in nuclear or cosmic apparatuses.

Abstract: Cavities such as vias (42) and contacts formed in semiconductor devices (41) are filled in a multi-stage process to provide low resistance electrical connections. A liner (46 1 ) is first deposited into the cavity (42) at a relatively low power and deposition rate to enhance "wetting" of a subsequently deposited fill material (46 11 ). The fill material (46 11 ) is deposited at a comparatively greater power and deposition rate to close the mouth of the cavity (42), after which the fill material (46 11 ) is extruded at high pressure into the cavity (42) to substantially fill the cavity (42). Relatively low processing temperatures and high pressures are utilized to allow for the use of lower dielectric constant dielectrics, which are thermally unstable at conventional processing temperatures.
