IPC: A61B8/06
Filed: 1988-03-28
Abstract: PURPOSE:To improve the detecting ability of slow blood flow velocity and to visually recognize the information of the speed and power of a blood flow by converting the difference in the blood flow power corresponding to the difference in chroma saturation and simultaneously providing a color processing means to convert a difference in the blood flow velocity corresponding to the difference in brightness. CONSTITUTION:The change of a blood flow velocity V is made to correspond to the change of a saturation S by a color processing means 36a, and the difference in the blood flow velocity V is displayed by the difference in the chroma saturation S. Since the change of a blood flow power P is made to correspond to the change of the brightness I along with the information of the blood velocity V, the difference in the blood flow power P is displayed by the difference in the brightness I, and the information of the blood flow power P is also simultaneously displayed. Consequently, since the slow blood flow velocity and fast blood flow velocity are displayed with the same brightness I and the part of the slow blood flow velocity P is clearly displayed in a bright color so as to be easily seen, the velocity can be clearly recognized even at the place of the slow blood flow velocity, and the detecting ability of the slow blood flow velocity P can be improved. Since the change of the blood flow power P is displayed corresponding to the change of the brightness I, the information of both blood flow velocity V and blood flow power P can be visually recognized clearly, and diagnostic ability can be improved.

Title: Picture information two-dimension coding system
Inventor: YOKOYAMA YOSHIHIRO
IPC: H04N1/417
Filed: 1987-03-30
Abstract: PURPOSE:To contrive to improve the compression rate of coding by converting plural consecutive path mode codes into one horizontal mode code and giving it as the output in a MR (Modified Read) or MMR(Modified MR) encoder. CONSTITUTION:Denoting the picture element 31 by a0 at first in the MR and MMR system, the picture element 37 is b1 and the picture element 38 is b2. Since no element a1 exists to the left of the element b2, the code is a path mode code and a new element a0 is set to the picture element 32 beneath the element b2 to generate a path mode code and similarly, the path mode code is being generated while setting the element a0 to the picture elements 33, 34. One horizontal mode is generated here to set the element a0 from the picture element 31 to the picture element 34. That is, let the picture element 31 be a0 and the picture element 34 is a1 and a2, then the code is generated by using the distance between the elements a0 and a1 and between the elements a1 and a2. Thus, the decoding is attained by using a decoder in compliance with the standards in the MR and MMR system and the compression rate is improved.

Title: Information processor
Inventor: KANEKO EIJI
IPC: G06F12/00
Filed: 1990-03-24
Abstract: PURPOSE:To improve the working efficiency of a CPU by controlling the wait signal to be applied to the CPU based on the output of a timer or the output given from a pulse generating circuit. CONSTITUTION:When a command is sent to a memory, etc., a wait signal 114 is immediately activated. At the same time, a timer 106 starts its counting action. The data outputted from a memory 101 are inputted to a comparator 103 through a bus 111. The comparator 103 compares the output data on a latch circuit 102 with the data on a bus 111 while the command is activated. When no coincidence is obtained between both data, a pulse is generated by a pulse generating circuit 104 and the signal 114 is inactivated. The signal 114 is activated by a command 113 and then inactivated by the output of the circuit 104 or the timer 106. As a result, the working efficiency of a CPU 100 is improved.

Title: Ghost removing device
Inventor: MURATA TOSHINORI
IPC: H04B1/10
Filed: 1981-05-19
Abstract: PURPOSE: To stabilize the operation of a ghost removing device for television by removing ghosts by a feedback system in normal cases and, at the generation of oscillation, by detecting the ghosts and changing the feedback system to a feedforward system in which oscillation is never generated.  
     CONSTITUTION: Since a video signal output level is low in normal cases, a ghost removing device feeds back ghosts to an adder 4 through a delay elements 2 with delay time γ and amplifiers 3 with gain-C n  (n=1∼3) constituting a transversal filter and removes ghosts included in a video signal input δ(t) by controlling the gains of the amplifiers 3 by an automatic gain controlling circuit 5 according to the difference between a reference signal and an output of the adder 4. If oscillation is generated in the ghost mode, the level of a video output signal g(t) is increased. Consequently, an output is generated from a level discriminating circuit 9, an electronic switch 8 is closed and the transversal filter operates in the feed forward mode, performing stable ghost reducing operation without the generation of oscillation.
