Title: Automatic gain control circuit
Inventor: CHIBA KAZUHIRO
IPC: H03G3/30
Filed: 1978-02-27
Abstract: PURPOSE:To constitute an AGC circuit with smaller number of the resistance group and change-over switch than conventional by providing plural units of the attenuation resistance which can be switched by the switch to the input circuit as well as to the negative feedback circuit. CONSTITUTION:The 1st resistance groups r1-re and the 2nd resistance groups R1-Rm feature the relations r1>r2>...>re and R1<R2>...<Rm respectively,  and at the same time are selected so that their gains may change by RAGC/m (dB)  and RAGC/m (dB) respectively. In the original state, r1 is connected to R1 to secure  the maximum gain. Now, the output voltage of the circuit is supposed to be e0,  and thus eO is compared with reference voltage VS. And the gain is lowered by  switch 4 if e0> VS is defined. In case e0>VS still continues even after selection of  re, r1 is connected again. And switch 4 operates after R2 is connected via 2nd  switch group 7. Thus, e0<VS is secured.

Title: Method for recording color image, color image-recording apparatus, and method for controlling recording of color image
Inventor: KOBAYASHI MASAFUMI
IPC: B41J2/325
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To effectively suppress hue fringes by dividing one line to a predeter mined count in a sub scan direction thereby forming sub lines and setting a false angle in a dot arrangement in a color image-recording apparatus forming recording dots of at least three colors. SOLUTION: One line is divided to a predetermined count in a sub-scan direction, thereby forming sub lines. When recording dots of at least three colors are to be formed on a recording medium, for recording dots of a first color, one dot is formed on any one of the sub lines for every line in the sub scan direction of each column in a main scan direction, and dots are formed on different sub lines in adjacent columns in the main scan direction. For recording dots of a second color, dots are separated by one sub line or more between a main line of an off number and a main line of an even number in the sub direction, thereby forming a first group of recording dots. Moreover, a different second group of recording dots is formed in sub lines in the adjacent columns in the main scan direction. The recording is controlled in this manner.

IPC: H05B6/12
Filed: 1990-01-31
Abstract: PURPOSE:To prevent the repetition of a meaningless notice to a user against a single noise by informing abnormality to the user only when the abnormal state of an inverter circuit is generated continuously for a prescribed time. CONSTITUTION:When a power supply voltage is abnormal, the abnormality detecting circuit 12 of a control circuit 11 decides that an inverter circuit 2 is in an abnormal state, and outputs a signal to an oscillation stopping circuit 13 and a timer circuit 14, respectively. Subsequently, the timer circuit 14 operates a timer as the abnormal state of the inverter circuit 2, but in the case this abnormal state is restored within four seconds, the abnormality detecting circuit 12 releases an output signal from its time point. In the case it is not restored, the timer circuit 14 outputs a signal to a display part 23 until the abnormal state is restored and the output signal from the abnormality detecting circuit 12 is released from its time point. In such a manner, as for a single impulse-like noise, it is not informed to a user every time.
