  • Patent number: 7163757
    Abstract: A secondary battery with high safety is provided. A heater and a diode are connected in series, and a thermistor is connected in parallel with thus formed series circuit. A fuse is connected in series with thus formed parallel circuit to form a protective circuit, which is attached to an accumulator to complete a secondary battery. In the case of overcharging, the accumulator generates heat so that the thermistor heats up to increase the resistance value. As a result, the current pass through the heater, which generates heat to break the fuse. In the case of short circuit, the diode is reverse-biased and no current passes through the heater so that the fuse does not break.

  • Publication number: 20060164927
    Abstract: The present invention enables audio data to be recorded or played back more easily. LPCM samples from an LPCM sample 301-1 of a first channel to an LPCM sample 304-1 of a fourth channel in audio data are combined in order to generate a GOLS 310-1. An even number of GOLS are combined to generate an audio frame. Header information is added to the audio frame to generate an audio PES packet, which is multiplexed with a video PES packet and recorded onto a recording medium. As a result, the number of bits of the audio frame is an integral multiple of 32. This increases an affinity with a recording and playback apparatus.

  • Patent number: 6367049
    Abstract: Multiword information is based on multibit symbols disposed in relative contiguity with respect to a medium, and is encoded with a wordwise interleaving and wordwise error protection code for providing error locative clues across multiword groups. In particular, the clues originate in high protectivity clue words (BIS) that are interleaved among clue columns, and also in synchronizing columns constituted from synchronizing bit groups. The synchronizing columns are located where the clue columns are relatively scarcer disposed. The clues are directed to low protectivity target words (LDS) that are interleaved in a substantially uniform manner among target columns which form uniform-sized column groups between periodic arrangements of clue columns and synchronizing columns.

  • Patent number: 5975912
    Abstract: Using plasma enhanced chemical vapor deposition, various layers can be deposited on semiconductor substrates at low temperatures in the same reactor. When a titanium nitride film is required, a titanium film can be initially deposited using a plasma enhanced chemical vapor deposition wherein the plasma is created within 25 mm of the substrate surface, supplying a uniform plasma across the surface. The deposited film can be subjected to an ammonia anneal, again using a plasma of ammonia created within 25 mm of the substrate surface, followed by the plasma enhanced chemical vapor deposition of titanium nitride by creating a plasma of titanium tetrachloride and ammonia within 25 mm of the substrate surface. This permits deposition film and annealing at relatively low temperatures--less than 800.degree. C.
