PURPOSE:To increase the manufacturing efficiency of an electrode for a lead storage battery by making the electrode by applying an active material paste to a sheet-like continuous body made of an alloy principally consisting of lead, being followed by cutting the thus obtained body into a given size before it is curled into a cylindrical shape the inner surface of which corresponds to the surface ...

An improved process for the preparation of cycloalkanols and cycloalkanones by the liquid phase oxidation of a cycloalkane having from 5 to 12 carbon atoms in the ring by means of a gas containing molecular oxygen to obtain an oxidation mixture containing cycloalkyl hydroperoxide and acids, and the subsequent decomposition of such cycloalkyl hydroperoxide to cycloalkanols and cycloalkanones. The d...

PURPOSE:To allow residual fault detecting circuits to detect errors effectively, by ignoring the output of a fault detecting circuit when the fault detecting circuit itself is faulty. CONSTITUTION:If the output of a parity check PC circuit 2A goes to 1 due to an error in contents of a register 1A, a clock stop signal is generated through a gate 4A, and this signal is inputted to an error latch 3A ...

PURPOSE:To monitor a system accurately, by presetting a time required for the next processing to a watchdog timer, which monitors the operation of a microcomputer, when it is the preset time. CONSTITUTION:When the number of pulses P1-P4 corresponding to the time to the next presetting is written in a register by a preset instruction, a write signal WT is inputted to a reset R2 pf a flip flop F2 an...
