Title: Manufacture of spiral battery
Inventor: KAWAI TETSUO
IPC: H01M6/10
Filed: 1982-03-13
Abstract: PURPOSE:To prevent any generation of irregular creases during rolling work by covering the inner and the outer circumference surfaces of a long electrode plate with separators, and joining the outer separator to the inner separator after providing the outer separator with slacks, and being followed by performing the rolling work. CONSTITUTION:A battery is constituted by rolling into spiral form a long negative plate 1, which consists of a lithium plate 2 and a current-collecting body 3, and a long positive plate 5, which is formed by making a positive mixture 6 to be held on a current-collecting body 7, with separators 8 provided on the surfaces of the positive plate 5. Here, after an inner and an outer separator 8a and 8b are provided over the entire surface of the positive plate 5, the outer separator 8b is provided with slacks 15 at given intervals, the ends of the separators 8a and 8b are fused together, and thus obtained unified body is subjected to rolling work. As a result, since stresses developed in the separators 8a and 8b during the rolling work can be absorbed by the stretches of the slacks 15, the rolling work can be performed while highly maintaining the close contact between the members, without causing any irregular creases.

Title: Manufacture of pipeline gas from sulfur-containing crude gasor synthetic gas
Inventor: JIYON HAPERU
IPC: C07C1/04
Filed: 1984-03-02
Abstract: Described is a process for producing methane-rich, pipeline-quality gas from raw gas produced by gasifying carbonaceous materials. Following any needed adjustment of its H2/CO ratio, which can be by a preconditioning water gas shift reaction or its reverse, the raw gas is fed to a direct methanation reaction (2H2 + 2CO-><- CH4 + CO2) which does not require substantial addition of steam. If needed, the intermediate product gas from the direct methanation reaction can be passed over a water gas shift catalyst to control its H2/CO ratio so that after removal of acid gases its methane content can be raised further over a nickel catalyst. This enables production of a very high heating value pipeline gas with only one acid gas removal step in the entire process sequence. In the alternative, the intermediate product gas can be subjected to cryogenic methane separation, with the separated H2 and CO fed back to the direct methanation and the separated methane used as SLNG. A preliminary direct methanation step can be carried out prior to any needed preconditioning step.

Title: Semiconductor memory device
Inventor: WATARI TAKASHI
IPC: G11C11/419
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To realize low power consumption and enable high speed access by dividing a sub sense amplifier circuit connected to the sub bit line pair selected by the same word line into two or more groups and then selectively connecting an output of the sub sense amplifier circuit to the main bit line pair with a connecting means as the group is made to be a unit. SOLUTION: When WL 21 is driven as the word line corresponding to the address to be accessed, a low level potential difference is generated on the sub bit line pair S1BL0 to S1BL5 corresponding to the memory cell selected by the word line WL21 and it is then amplified up to the predetermined potential difference by the connected sub sense amplifier circuit. A potential difference of the sub bit line pair S1BL0 to S1BL2 in relation to the switch control signal G0MBT1 corresponding to the driven word line WL21 appears as the low level potential difference of the main bit line pair MBL0 to MBL2. Since only the connected sub sense amplifier operates, power consumption can be lowered.

Title: High-speed switching thyristor
Inventor: SUEOKA TETSUO
IPC: H01L29/10
Filed: 1978-04-04
Abstract: PURPOSE:To increase the area utilization rate and to reduce greatly the turn-off time by providing the P<+> layer within the P2 layer of the P1N1P2N2 structure to use it as the gate electrode to be led out to outside and then providing the short- circuit hole at the area opposing to the P<+> layer of the N2 layer. CONSTITUTION:The P<+> gate layer buried with the fixed pattern is formed within the P2 layer, and the plane form is discributed in the form of the trochoid curve or the radiant ray from the center toward the circumference. And electrode G is provided at the center part which is drilled up to the P<+> layer to be then led out to outside. For the N2 layer, short-circuit part 7 is provided at the position coincided with the pattern of the P<+> layer and the surface of the electrode is short- circuited with the cathode N2 via electrode K. In such constitution, displacement current id of junction N1P2 flows into the P<+> layer to fail to secure the direct forward bias for junction P2N2. On the other hand, reverse bias current iv to be applied to junction P2N2 flows directly to the P<+> layer from short-circuit part 7 with virtual no bias given to junction P2N2, thus increasing the gate reverse bias effect. Furthermore, the area utilization rate becomes almost double, with the allowance current and the overcurrent rating increased more than double each.

Abstract: PURPOSE:To surely detect its own preset frequency and to prevent interference occurring by fetching voltage data from a voltage conversion means, and comparing the voltage data with preceding voltage data stored in an internal memory. CONSTITUTION:A microprocessor 22 sets the damping quantity of an attenuator 20 at 0dB, and fetches the voltage data from an A/D converter 21. When the voltage exceeds a threshold value, it is judged that the possibility of the reception of a frequency signal set at its own exists, and the data is stored in the internal memory. Then, the damping quantity of the attenuator 20 is changed to 1dB. At such a state, the data of the converter 21 is fetched again, and a difference between the preceding data stored in the internal memory is found, and when the difference is less than 2dB, it is judged as the preset frequency, and a carrier detecting signal is outputted, and transmission is prohibited. Thereby, it is possible to surely detect the preset frequency, and to prevent the interference occurring by prohibiting the transmission.
