Patent JP-S5916782-A (JP)
Title: Image-forming method
Inventor: HARADA TETSUYA
IPC: H01J31/50
Filed: 1982-07-20
Abstract: PURPOSE:To obtain a simple and inexpensive radiograph without requiring any darkroom work, by a method wherein a radiation-converting panel provided with a stimulatable fluorescent substance layer for accumulating radiation image information is scanned with light of the first wavelength, the radiation image information thus accumulated is read as light of the second wavelength, and is subjected to photoelectric conversion and scanning with an electric current. CONSTITUTION:When a body 2 to be phototgraphed is placed between a radiation generator 1 and the panel 3 andis irradiated with a radation, the radiation is transmitted through the body 2 in accordance with the radiation transmittance of each part of the body 2, and a transmisssion image is projected to the panel 3. As a result, electrons or positive holes the number of which is proportional to the quantity of the radiation absorbed into the fluorescent substance layer are generated, and are accumulated at a top level of the substance. Namely, an accumulated image of radiation transmission images is formed. Then, the accumulated image is developed by exciting by light energy. The intensity of the fluorescent rays irradiated is proportional to that of radiation energy, this optic signal is converted into an electrical signal by a photoelectric converter 6 such as a photomultiplier tube, and an image is regenerated on an electric current sensitized recording material 8 by scanning with an electric current.

Title: Motion detecting circuit
Inventor: KOYAMA KO
IPC: H04N19/136
Filed: 1991-05-30
Abstract: PURPOSE:To prevent accuracy for detecting motion from being lowered by detecting the motion of an image signal at a low level while lowering the sensitivity of motion detection, and preventing the sensitivity of motion detection from being lowered to the image signal which differential signal is higher than a noise level. CONSTITUTION:A subtraction circuit 102 calculates the absolute value of difference between an input signal and the image signal of a frame memory 101. The image signal of the circuit 102 is passed through a low-pass filter (LPF) 103 so as to reduce the high frequency component, and a differential signal ML is obtained for detecting the motion of the image. A noise level signal NL is obtained for the input image signal of a noise detection circuit 104 and inputted to a comparator circuit 105. The circuit 105 compares the signal Ml with the signal NL and outputs a control signal SEM at a high level when the signal ML is larger or outputs a control signal SEM at a low level when the signal ML is smaller. Therefore, when the signal SEM is at the high level, a control circuit 106 outputs the signal ML as a motion detecting signal MD as it is and when the signal SEM is at the low level, a signal multiplying 0.5, for example, to the signal SEM is outputted as the signal MD.

Title: Clock changeover method for ring network
Inventor: SATO SHIZUE
IPC: H04B10/07
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of clock path changeover as much as possible avoiding the occurrence of an independent synchronization state using an internal clock. SOLUTION: A master node 30 is operated with a clock signal extracted from data transmitted through an optical transmission line 50. Furthermore, the master node 30 transfers a quality code; Q=2 received from the optical transmission line 50 to a downstream node (slave node 40). In this state, when external clocks 1, 2 are recovered from their fault state, the master node 30 does not release the assignment of a quality code; Q=9 denoting inhibition of selection of the external clocks 1, 2. That is, the master node 30 does not execute the switch-back to the external clocks 1, 2 even when either or both of the external clocks 1, 2 are restored. Thus, a quality level is given to each of selectable clocks and on the occurrence of a fault in a clock in use, a clock with a highest quality level is selected among a higher clock or a selectable clock where the fault is restored.

Title: Tandem master cylinder
Inventor: MATSUMURA YOSHIHIRO
IPC: B60T11/224
Filed: 1979-10-03
Abstract: PURPOSE: To permit a great amount of presurized liquid to be discharged into a failed system until liquid pressure in the remaining normal systems reaches a predetermined value in a cylinder wherein rate of produced liquid pressure to pedal stroke varies with the rise of the produced liquid pressure by two steps.  
     CONSTITUTION: When one brake system connected to a discharge port 65 fails and a rod 17 is urged forward in braking, both stepped pistons 10, 25 are pushed forward to pressurize liquid in a high pressure chamber 30 while liquid pressurized in a low pressure chamber 13 is supplied through a path 16 to the chamber 30. Since liquid pressure is not produced by this pressurized liquid in a liquid pressurizing chamber 28 at the failure side, the piston 25 is continuously urged forward. As the push of the rod 17 is enlarged and the liquid pressure in a chamber 13 exceeds a predetermined value, the pressurized liquid is discharged through a relief valve 19 to a reservoir 3. Only liquid in the chamber 30 is pressurized highly by the push of the rod 17 and supplied to one brake system through a discharge port 61.
