Patent JP-H0548585-A (JP)
Title: Signal transmitter
Inventor: KINEKAWA YASUKAZU
IPC: H04L25/03
Filed: 1991-08-09
Abstract: PURPOSE:To properly discriminate the quality of transmission even when noise on transmission line increases and noise overlaps a receiving signal, and to suppress degradation of transmission quality. CONSTITUTION:Noise level detecting circuit 6 detects the noise level of transmission channel 2, and controls the criteria for transmission quality in accordance with noise level. Further, the noise level detecting circuit 6 limits the frequency band of sending signal, intensifies the amplitude of sending signal, enhances the threshold value for detecting receiving signal, and lowers transmission rate of sending signal. Accordingly, when due to lowering of S/N ratio a jitter occurs in equalizing receiving signal, if transmission quality is high, the signal transmitter eliminates erroneous discrimination and can appropriately discriminate transmission quality. Also, the execution of each above-mentioned control can suppress the degradation of transmission quality.

Abstract: PURPOSE:To prevent insulation breakdown from occurring even in the case that the voltage drop at current application is great by dividing one conductivity type region in the direction of crossing the longitudinal direction of a resistor. CONSTITUTION:A resist layer 7 having an opening at the diffusion resistor formation region of an n-type silicon substrate 1 is formed, and after implanting ions of p-type impurity annealing is done so as to form a p-type region 2. Next, a resist layer 8 is formed, and then by patterning it, openings 9 that the width corresponding to the longitudinal direction of the resistor is a and the width in the direction crossing this at right angles is b are formed in a plural number so that the space between each opening may be c. In this case, the opening 9 is so formed as not to contact with the n-type silicon substrate 1. Next, after implanting ions of n-type impurity, annealing is done so as to form an n<+>-type region 3. Next, using a CVD method, silicon-dioxide layer 4 is formed at the surface, and by patterning it an opening is formed at a region for forming contact region 5, and then p-type impurity is diffused so as to form a p<++>-type contact region 5, and an electrode/wiring 6 is formed and diffusion resistor is formed. Hereby, the voltage which is applied between it and one conductivity type region divided from an opposite conductivity type region becomes lower than the breakdown voltage at a P-N junction part, and generation of insulation breakdown can be prevented.

Abstract: PURPOSE:To arbitrarily select whether blank pages should be transmitted or not. CONSTITUTION:Picture information read by a document read means 2 is stored in a document information storage means 3. It is judged whether this picture information is a blank paper or not by a blank page judging means 4. In the case of a blank paper, transmission or non-transmission is determined by the classification of the transmission mode set to a transmission/non-transmission setting means 5. That is, blank pages are not transmitted at all in the case of the blank paper skip mode. In the case of blank page transmission mode, blank pages are transmitted by a transmission means 6 as they are. In the case of the both sides blank page skip mode, both sides of the document are not transmitted if both sides are blank, but the blank page is transmitted if only one side is a blank paper. Thus, transmission of unnecessary blank pages is prevented, and blank pages are transmitted at the time of bookbinding on the reception side.
