Title: Band compensation circuit
Inventor: GONDO KENJI
IPC: H03G5/16
Filed: 1990-03-07
Abstract: PURPOSE:To emphasize a low frequency component and a high frequency component relatively only when a level of an input signal is small by adding a signal resulting from amplification of an input signal uniformly over the entire band and a signal component subject to amplitude limit by a two-way clip circuit amplifying only a low frequency component and a high frequency component whose one terminal connects to a constant voltage source and outputting the sum. CONSTITUTION:The circuit consists of a full band amplifier 4, a low frequency high frequency component amplifier 5, an adder 7 adding outputs of both the amplifiers 4, 5 a constant voltage generator 6 and a two-way limiter circuit 3 connecting between an output point of the constant voltage generator and an output point of the low frequency high frequency component amplifier 5. Since an output of the low frequency high frequency component amplifier 5 does not activate the two way limiter circuit 3 when an input level of the input signal is low, a signal whose low frequency and high frequency component only is amplified is outputted, and when the level of the input signal is high, the two-way limiter circuit 3 is activated to limit the input level to a prescribed level. Thus, an output signal whose low frequency and high frequency component is emphasized is obtained only when the level of the input signal is low.

Title: Phase locked loop circuit for wide frequency band
Inventor: ATOBE MASAAKI
IPC: H03L7/10
Filed: 1989-03-09
Abstract: PURPOSE:To facilitate the design of a loop parameter which can use a phase lacked loop for input frequencies in a wide range by setting the frequency- dividing rate of a frequency-dividing circuit in a feedback system to be variable, and installing a frequency conversion means which can vary a conversion frequency after VCO in the feedback system. CONSTITUTION:The oscillation frequency fV of VCO(voltage controlled oscillator) 3 generates the local oscillation frequency fL of a local oscillation circuit 13 and two frequency fV+fL and fV-fL in the frequency conversion circuit 4. Furthermore, only fV-fL is inputted to the frequency-dividing circuit 6 which can vary the frequency-dividing rate N by a filter circuit 5 and is frequency-divided into 1/N. Consequently, any frequency (fV-fL) can be obtained by considering a combination with N and by optionally selecting fL. Thus, pull-in is attained in the input frequency in a wide band and the design of the loop parameter is facilitated even in a phase locked loop circuit using VCO 3 which has only the oscillation frequency range of a narrow band and which is highly stable.

Title: Thermal transfer recording medium and thermal transfer recording device using said medium
Inventor: NAKAZAWA KIYOTO
IPC: B41J31/00
Filed: 1990-03-08
Abstract: PURPOSE:To obtain a thermal transfer recording medium which enables realization of a high-quality printing at high speed and low power consumption by constituting said medium with a support which has a relatively high thermal conductivity in a vertical direction with the plane direction of the support and an ink layer. CONSTITUTION:The subject thermal transfer recording medium consists of a support 3 having a relatively high thermal conductivity in a vertical direction with the plane direction and an ink layer 4. Under this constitution, it is possible to allow a preferential flow of heat generated by a thermal head in the ink layer 4 and prevent the heat from being dissipated in the plane direction of the support 3. In addition, a sufficient amount of heat generated by the thermal head is conducted to the ink layer 4 because of the relatively high thermal conductivity in the vertical direction to the plane direction of the support 3. At the same time, the temperature of a protecting film of the thermal head rather reduces compared to that of a conventional thermal head. Thus this phenomenon contributes to the thermal efficiency and life of the thermal head.
