Patent JP-S58194544-A (JP)
Title: Recording apparatus
Inventor: SAITOU SEIJI
IPC: B41J19/14
Filed: 1982-05-11
Abstract: PURPOSE:To make it possible to obtain a high quality image, in a dot matrix printer, by arranging M rows of recording element groups of which N numbers of K/N come to simple fractions at K dot intervals in an auxiliary scanning direction so as to be shifted only over a distance (l) being the integer-fold of N. CONSTITUTION:A recording head 15 has nozzle heads 15Y-15BK of yellow Y, magenta M, cyan C and black BK while each head has N=3 numbers of nozzles arranged at K=4 dot intervals such that N numbers of K/N come to simple fractions in an auxiliary scanning direction and arranged at L=2 dot intervals in a main scanning direction in a stepwise form set back every at l=3 dot intervals. In this case, the recording head 15 is reciprocally moved at one dot interval to respectively carry out recording every one main scanning line SLn and recording paper 3 is subsequently sent over a distance corresponding to three dots to repeat similar operation. Therefore, because a color ink is superposed after the previously emitted color ink is sufficiently dried, the lowering in image quality can be avoided and, because the superposing order of the color ink is same in a reciprocal direction, the difference in color tone is not developed and a high quality color image can be obtained.

Title: Amplifier
Inventor: KAWAMURA MASAAKI
IPC: H03F1/08
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide the amplifier in which secondary distortion is suppressed. SOLUTION: When a high frequency input signal is given to the amplifier, a capacitor C1 cuts off a DC component and the resulting signal is given to a gate of a field effect transistor(TR) Q1, a drain current is controlled to amplify an input signal an outputted from a high frequency output terminal via a capacitor C2. A resistance of a resistor R2 is set to an optional resistance to apply a current feedback and the higher the drain current is, the more the drain current is suppressed so as to suppress secondary distortion of the field effect TR Q1. Although the mutual conductance is changed secondarily with respect to the gate voltage, since the drain current changes nearly linearly with respect to the gate voltage, the secondary distortion is reduced in a range of a prescribed gate voltage.

Thus the priority order of both circuit under a busy mode is displayed on the device 11. The speaker of an extension telephone B knows an incoming state of an outsider with an interrupting incoming tone and refers to the service class shown on the device 11 to know at a glance the priority order among the telephone B, an extension telephone A and the outsider having an interrupted incoming request. Then the speaker can decide the degree of emergency to an answer.
