Title: Digital communication modulation method
Inventor: HIRABAYASHI MASASHI
IPC: H04L27/26
Filed: 1991-10-03
Abstract: PURPOSE:To attain the modulation in which the effect of an echo due to multiple reflection or the like is hardly caused and a sophisticated electronic device such as a DSP is not required by representing an input pulse train with on/off of a sine wave and allocating a modulation wave having a different frequency to a designated time location of the pulse train. CONSTITUTION:A time width of deltaT is divided into, e.g. 1/4 depending on number of bits, a frequency component (sine wave) of f1-f4 is allocated to each division, and a coding signal is formed depending on whether a frequency component is in existence to each time zone. An error occurrence probability depends not on the width of deltaT itself but on the width of deltaT/4 of a part in which the frequency component is allocated. Thus, when the presence period deltaT' of the frequency component is set to a half of the deltaT/4, the error occurrence probability is equivalent to the case of the halved conventional deltaT as deltaT/2, and the probability of error occurrence is reduced by approximated equation of the occurrence probability of the error. The error occurrence rate is reduced by making the width deltaT' for the frequency component period allocation narrow in this way.

Abstract: PURPOSE:To obtain a converting circuit having the optional bit length of an input by dividing an input bit string excluding upper two bits into groups equal to the number of fixed bits and supplying each group to the corresponding converters of the same type with the upper two bits supplied in common to all converters. CONSTITUTION:A control input IC pin is used for input of the signal showing that the '0' or '1' string starting at the 1st bit of the URR expression is continuous with the same value for converters up to the preceding stage. While a control output CO pin is used for output of the signal showing that the '0' or '1' string is continuous with the same value up to the corresponding converter. Thus for converters are connected longitudinally in the order of bit numbers of a URR input register 30 by both CI and CO pins. However '1' is supplied to the CI input pin of the head converter 2a and the signals of the CO input pin of the last converter 2d are continuous in terms of the URR expression in a URR register. Thus the signals are obtained with no intermission of the '0' or '1' string.

Title: Optical detecting device
Inventor: ITABASHI AKIHISA
IPC: G02B26/10
Filed: 1989-10-03
Abstract: PURPOSE:To prevent a still ghost image from being generated with photodetection lens reflected light by arranging the optical axis of a photodetection lens at a position which shifts or rotates from the incidence optical path of a light beam. CONSTITUTION:The optical axis of the photodetection lens 7 is shifted from the incidence optical path of the light beam Lb. Namely, the light beam Lb is made incident obliquely to the surface 7a of the photodetection lens 7 on the side of a rotary polygon mirror, so even if the light beam is reflected by the surface 7a, the light does not return to the rotary polygon mirror and no still ghost image is formed on a scanned medium. Further, the optical axis of the photodetection lens 7 is rotated and slanted to the incidence optical path of the light beam Lb. In this case, the reflected light from the surface 7a does not return to the rotary mirror either and no still ghost image is formed on the scanned medium. Thus, the still ghost image is prevented from being formed with the reflected light.
