摘要： A control unit forms a control center serving as one type of a control panel in an electric power system control system. The control unit accommodates equipments such as a circuit breaker, an electromagnetic switch, a zero-phase current transformer, and an operating transformer, and includes a substantially Z-shaped equipment mounting plate mounted between side plates of the unit to have an intermediate bent portion. The circuit breaker is disposed on a front face of a front mounting portion of the equipment mounting plate, and the current transformer is disposed on a back face thereof. The electromagnetic switch is disposed on a front face of a back mounting portion of the equipment mounting plate, and the thin operating transformer is isolated from other equipments and disposed on a back face thereof. Mounting the thin operating transformer on the back face of the back mounting portion of the equipment mounting plate causes the control unit to contain a bulk electromagnetic switch and other equipments without increasing a control unit size. Further, since the operating transformer is isolated from other equipments, other equipments are never affected in the event of burning accident.

摘要： A digital speedometer includes a pulse counter, a timing pulse generator, an indicator register, a display, and a comparator for comparing the magnitude relationship between a counted value counted by the pulse counter and the memorized value of the indicator register, two counters in addition to the pulse counter, and a plurality of logic circuits. The comparator generates signals indicative of the magnitude relationship between the counted value and the memorized value. The two counters may output a first or second gate signal respectively to the AND gate connected to the indicator register, in response to the signals output from the comparator at a predetermined time cycle depending upon the gate time controlled by the timing pulse generator, in such a manner so as to renew the memorized value with the counted value only when the number of occurrences of the output of the first or second signals reaches a preset number thereof. The digital speedometer further comprises a decision circuit for renewing the memorized value with the counted value of the pulse counter only when the memorized value is 0, regardless of the number of occurrences of the output of the first or second signals counted by either of the two counters.
