Title: Ultrasonic diagnostic apparatus
Inventor: YAMADA ISAMU
IPC: G01N29/44
Filed: 1987-06-26
Abstract: PURPOSE:To remove the effect of the diffusion of ultrasonic beam and to estimate accurate beta(z), by providing either one of a means for correcting the detection signal of a medium on the basis of the detection signal obtained from a uniform reference phantom wherein the frequency dependence beta of the attenuation coefficient of the medium is know and a means for correcting the beta estimated value of said medium using the value when beta of said reference phantom is estimated. CONSTITUTION:The gathering average <yc(z)> of a plurality of the detection signals from a uniform reference phantom wherein beta(z) is known is obtained. Further, beta(z) of the uniform reference phantom at this time is set to betac. Next, the detection signal y(z) from an objective medium is obtained (Fig. b). Subsequently, DELTAy(z)=y(z)-<yc(z)> is calculated (Fig. c) and formula (1) (wherein z is a variable in a depth direction) is adapted thereto and the estimated value beta''(z) of beta(z) is calculated (Fig. d). beta(z) of said medium is beta'(z)=beta''(z)+betac from formula (6) [wherein beta'(z) is the estimated value of beta(z) of the medium, beta''(z) is a result when DELTAy(z) is used in place of y(z) of formula (1) and betac is the real beta(z) of the reference phantom] and, therefore, a value wherein only betac is added to Fig. d becomes the estimated value beta'(z) (formula 6) of beta(z) of the medium (Fig. e).

Abstract: PURPOSE:To uniformize printing quality by outputting suitable amount of blank to the start of printing by avoiding a chattering period due to the contact of a sheet face with a handy printer at the initial of printing to remove a character distortion at the initial of printing. CONSTITUTION:A printing time of the printing period 2 of 9 is decided by applying the feeding speed calculated by the total sum of (the processing time 1 in the printing period 1 of 8) + (printing time 1 of 11) + (waiting time 1 of 12) to (feeding speed)-(printing time curve) table, and a basic pulse determined by the product of a capacitor value and a resistance value of causes for determining a time constant of a multivibrator are superposed by triggerrable operation to obtain a printing time. Further, a character configuration is deformed due to the irregularity in a speed signal obtained by a speed detector of 4 of a character at the start of printing in contact of the head of a handy printer with a sheet face. Its cause is that the detector is chattered at the contact with the sheet face. here, in order to uniformize printing quality, suitable amount of blank is added after the detection of the start of printing by a pulse of printing starting end from the detector, and printing is started after the lapse of a chattering region.
