Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To correct a frequency error by preparing a clip circuit where the rectifying devices having the dead bands at low voltage parts are reversely connected in parallel to each other to set the peak-to-peak amplitude of the base band signal of output of a frequency discriminator at the width of the said dead band and to control the frequency of a voltage control oscillator. SOLUTION: A clip circuit 9 where the rectifying devices having the dead bands at low voltage parts of the silicone epitaxial diodes, etc., are reversely connected in parallel to each other is prepared. The FSK(frequency shift keying) signal that is added to a signal input terminal 1 undergoes the detection of frequency by a frequency discriminator 4 via a frequency converter 2 and an IF(intermediate frequency) amplifier 3 and is turned into a base band signal. Then the peak-to-peak amplitude of the base band signal is controlled by an amplitude control circuit 8 to be equal to the said dead band and added to the circuit 9. Thus, the circuit 9 adds the output accordant with the frequency error of the FSK signal to a loop filter 10 and drives a voltage control oscillator 11 to correct the frequency error.

Title: Thermal transfer recording method
Inventor: SAKURAI HIDEO
IPC: B41M5/40
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To perform good heat storage and record full color images with a small quantity of power in a thermal transfer recording method, by constituting so that a transfer direction of an ink sheet and a transfer direction of a receiving paper are opposite to each other. SOLUTION: When a colorant in an ink sheet 1 is to be thermally transferred and recorded to a receiving paper 4 by heating the ink sheet 1, the ink sheet 1 and receiving paper 4 are transferred in 180 deg. opposite directions. When the thermal transfer recording is started, temperatures of the ink sheet 1 and receiving paper 4 are raised by the heat from a thermal head 2 (parts where the temperatures are raised are hatched). At this time, the hatched part of the receiving part 4 is brought in touch with a paper of the ink sheet 1 not yet used which is supplied to the thermal head 2, whereby the heat is applied from the receiving paper 4. Accordingly, the ink sheet is in a state 5 already preheated when the recording is started, and an energy required for the thermal transfer recording is reduced.
