In a real-time video signal processor for processing an input digital video signal divisible into a succession of principal blocks each of which has at least one scanning line and a time duration shorter than a frame period, each principal block is divided into at least two partial blocks with each scanning line divided into the respective partial blocks. A plurality of signal processing modules are assigned with the respective partial blocks of each principal block, respectively. Responsive to the input digital video signal and an additional digital video signal, the signal processing modules process the respective partial blocks of each principal block into processed signals during the time duration, respectively. Each processed signal comprises a first partial signal used as an output signal of the processor and a second partial signal. A delaying circuit delays the second partial signals derived from the signal processing modules into a delayed signal having a delay equal to a difference between the frame period and the time duration. The delayed signal is used as the additional signal. A plurality of the real-time video signal processors may be connected in cascade to each other. Two memory units may be used instead of the delaying circuit. Readout operation of each principal block from the memory units is controlled by control signals produced by a control signal producing circuit. Principal blocks read out of the memory units are supplied to the signal processing modules.

A heat-resistant electrically insulated wire has a composite coating layer of a mixture of an inorganic fine powder and an inorganic polymer on a conductor and the composite coating layer has a resinous overcoat layer thereon. The composite coating layer has not artificially been fired, but is adapted to be converted into a ceramic layer when exposed to elevated temperatures during use.

Heat-resistant electrically insulated wires and a method for preparing

A small electric motor, for example for driving a clock comprises a capsule within which are provided a stator, a rotor and a deceleration gear train. One wheel in the deceleration gear train bears a pattern on its periphery for indicating the state of operation of the motor. The capsule is either transparent or is provided with a window for observing the wheel bearing such pattern.

A buzzer mechanism for an alarm clock or the like comprises a vibrator member rockably supported on a base plate for angular movement between an inactive position and an active position in which a vibration arm of the vibrator faces a buzzer yoke associated with the alternating driving coil of the clock so as to be vibrated. A coil spring presses the vibrator member against the base plate and also biases it toward active position. A projection on the vibrator member engages the hour wheel so that when the hour wheel is moved axially upon a projection on the hour wheel coming into registry with a hole in an unlocking drum, the vibrator member is permitted to rock to active position. An alarm stop lever is operable manually to return the vibrator member to inactive position.
