Title: Gain variable device
Inventor: MORITA TOMOO
IPC: H03G7/00
Filed: 1982-05-25
Abstract: PURPOSE:To suppress an increase in noise when no signal exists, by obtaining a voltage proportional to an input signal when it exceeds a certain level, obtaining a voltge inversely proportional to the input signal in other low levels or below, and controlling a voltage controlled amplifier with these voltages. CONSTITUTION:When the input signal exceeds a certain level V1, a compressing control signal generating circuit 2 outputs a signal proportional to the input signal. When the input signal reaches other level V2(V2<V1) or below, an expanding control signal generating circuit 3 outputs a signal inversely proportional to the input signal. A control circuit 4 outputs said signal to a voltage controlled amplifier circuit (VCA) 1 as a control signal when an output of the control signal generating circuit 2, 3 is a voltage or over. The output of the VCA1 follows a line tying points A, B', C' and D when the rise or fall of the input signal is gentle and follows a line coupling points A, B, C, D when further more gentle. The output follows a line A-D when steep.

Title: Broken line approximating circuit system
Inventor: TAKEUCHI SHIGERU
IPC: H03G11/08
Filed: 1981-06-12
Abstract: PURPOSE:To realize a conversion of high accuracy, by controlling a variable attenuator provided at the front stage of a broken line approximating circuit in accordance with the level of the input signal. CONSTITUTION:The output signal VO' of a broken line approximating circuit is fed to a voltage comparator COMP, and the COMP decides whether the conversion output voltage VO' is within the allowable voltage range VL-VH. When the voltage VO' gets out of the above-mentioned range, this information is transmitted to a control circuit. Thus the degree of attenuation is controlled for a variable attenuator to set the voltage VO' within said range. Then the input signal V1' is controlled. As a result, the conversion is always possible within a range of a small linearilty. At the same time, a D/A converter is provided to produce the voltage that gives the backward compensation by a degree equivalent to the attenuation given by the variable attenuator after receiving the control signal in order to perform the compensation to the control of level. The output voltage of the D/A converter is added to the signal VO' to obtain an output signal VO.

IPC: H03F3/217
Filed: 1990-04-03
Abstract: PURPOSE:To make high efficiency by operating a 1st switching circuit employing a power MOS.FET with a small gate input capacitance when an output power is small, and operating a 2nd switching circuit employing a power MOS.FET with a small on-resistance when the output power is large. CONSTITUTION:When an output power POUT is small, the input gate capacitance is small and power MOS.FETs 14a, 14b each with a large ON-resistance act like switching elements. When the output power POUT of a speaker 8 gets large and exceeds a prescribed setting level, 3rd and 4th MOS.FETs 15a, 15b with less on-resistance and large gate input capacity being components of a 2nd switching means 15 act like switching element. Thus, the gate input capacitance charge/discharge power is reduced in a region where the output power is small and the increase in the power loss is decreased in a large output region. Then the power loss is made small and high efficiency is attained independently of the quantity of the output power.

Abstract: PROBLEM TO BE SOLVED: To obtain an image having stable recording quality even when errors present in the carrying speed of a recording medium and the mounting accuracy of a recording head by a method wherein the recording medium is shifted by a distance between a specified number of dots in every one recording run of the recording heat to the direction of its recording line. SOLUTION: By driving a scanning motor 3 with a controlling part 9, a recording head 1 is shifted to its main scanning direction under the condition that the recording head is guided by a shaft 2 and ink is delivered during the shifting of the recording head so as to perform an one-time image recording. When the one-time image recording comes to an end, the controlling part 9 drives a carrying motor 8 so as to advance a recording medium 5 by the distance between P dots (in which N=P+1) as a certain distance to the sub- scanning direction of the recording head. Then, the recording head 1 is sent back to its initial position so as to perform the second-time image recording again. Afterwards, the shifting action of the recording medium by P dots after the one-time image recording is repeated until the recording of the whole information data comes to an end. Accordingly, an image having stable recording quality can be obtained.
