An information processing system includes a plurality of functional blocks (neurons) and a data bus for transmitting in common the outputs of the individual functional blocks (neurons). Data transaction among the functional blocks (neurons) is performed through the data bus on the time-division basis. For preventing the outputs from conflicting or competition, addresses are assigned to the individual blocks (neurons), respectively, so that only the functional blocks (neuron) having the own address designated by the address signal supplied through an address bus outputs data signal onto the data bus, while the other functional blocks (neurons) receive the information on the data bus as the signal originating in the functional block whose address is designated at that time point. The addresses are sequentially changed. During a round of the address signals, data are transmitted from given functional blocks (neurons) to other given functional blocks (neurons).

The flux composition is present in an amount of 8 to 25 wt. %, based on the total amount of the steel sheath and the flux composition. The flux composition comprises, based on the total weight of the flux, 10 to 30% of TiO.sub.2, 0.1 to 0.6% of Na.sub.2 O is in the range of 20 to 100:1, 0.01 to 2.0% of a metal fluoride calculated as F, and 0.005 to 0.4% of moisture. Bi.sub.2 O.sub.3 may also be included in the composition.
摘要:
A semiconductor integrated circuit for controlling the substrate potential is disclosed, in which a substrate potential generating circuit is connected to a substrate and can be operated on at least a certain operation voltage level to generate the substrate potential. A detection circuit outputs a first detection signal upon detecting that the substrate potential has become lower than the operation voltage level by more than a preset amount, and outputs a second signal upon detecting that the substrate potential has reached a preset level which is slightly lower than the operation voltage level. A charging circuit charges the substrate upon receiving the first detection signal and interrupts the operation of charging the substrate upon receiving the second detection signal.
摘要:
An apparatus for controlling an operating stroke of a reciprocating member to be reciprocated by a drive motor. The apparatus includes an encoder adapted to generate pulses each of which corresponds to a predetermined incremental distance of movement of the reciprocating member, a counter for counting the pulses during movement of the reciprocating member in a forward direction, a device for converting the operating stroke into the number of the pulses corresponding to a multiple of the incremental distance of movement, and a residual distance which is a difference between the operating stroke and the multiple, a device for converting the residual distance into a corresponding residual time, and a device for commanding the drive motor to stop an operation thereof causing a further forward movement of the reciprocating member, when the residual time has elapsed after a count of the counter is equal to the above-indicated number of the pulses.
