摘要： In a mobile communication apparatus having a codec which codes first voice data into second voice data and decodes the second voice data into the first voice data, a memory in which the second voice data should be recorded and a silent data generating unit which generates silent data, the second voice data is successively recorded in the memory. While the second data is being recorded, the silent data is recorded in the memory as a substitute for the second voice data which is in a first state. The first state is a state in which the second voice data may be noise data.

摘要： In forming a color picture image on a photosensitive recording medium by exposing through a masking master plate, the plate is conveyed by a conveyor belt into an exposure device where the plate must be registered in a specified position to avoid a color shift in the image formed on the photosensitive recording medium. A positional error or deviation of the plate is detected by reading out a location mark on the plate by a plurality of sensors. According to the outputs from the sensors, the conveyor belt is moved in a longitudinal path by one or two motors to correct a longitudinal deviation, and two longitudinally spaced portions of a belt support unit are moved, in a direction perpendicular to the longitudinal path, independently and respectively by other two motors to correct a transverse deviation and/or a skew.

The automatic frequency control circuit for processing frequency control of a received signal frequency based on an incoming received signal comprises a first control circuit for processing frequency control based on a precision counter by using the incoming received signal and a second control circuit for processing frequency control based on a coarse counter by using the incoming received signal, wherein the first control circuit and the second control circuit are configured to be used interchangeably in response to the incoming received signal. By employing the circuit which directly counts the received signal and the circuit which counts the regenerative carrier signal in combination, the follow up range of the automatic frequency control circuit is thus expanded.
