Title: Recording/reproducing method of radiation image
Inventor: SHIMURA KAZUO
IPC: H04N5/325
Filed: 1991-03-27
Abstract: PURPOSE:To achieve reproduction to a state with excellent contrast and sharpness by eliminating effect of scattering lines caused by an object in photographing when a radiation image is reproduced based on an image signal obtained by reading out the radiation image recorded on a recording medium. CONSTITUTION:An original image signal Sd obtained by a reading processing of a storage fluorescent sheet 13 is smoothed with an image processor 32 to obtain a differential signal S2=Sd-S1 between smoothing image signal S1 and the original image signal Sd. Then, a scattering line distribution signal S4 is obtained from the signal S3 which is calculated by an equitation S3=S2+Qc (Qc is a constant), and a signal Sp=S1-S4 is sent to an image reproducer 3 to reproduce a radiation image.

IPC: H05K3/24
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To reinforce the solderability on the surface by using immersion silver coating as a solderability preservative. SOLUTION: The surface is immersion-plated with silver by a thickness of 1 to 100 microinch, and this silver plating is directly soldered.

Abstract: PURPOSE:To make it possible to clamp a workpiece without deforming the latter, by providing a reference guide which may change its position in the direction substantially orthogonal to the workpiece transfer direction and a cylinder for pressing the workpiece against the reference guide. CONSTITUTION:A reference guide 2 is arranged on one side of a transfer path for a workpiece (a) which is transferred by a conveyor 1, so that the guide 2 may change its position in the direction substantially orthogonal to the transfer direction of the workpiece (a), and a cylinder 3 for pressing the workpiece (a) against the reference guide 2 is arranged along the transfer path on the side in opposite to the reference guide. Thus, when the workpiece (a) reaches substantially the position of the reference guide 2, the conveyor 1 is stopped, and is then a motor 5 is driven to shift the reference guide 2 which is therefore substantially abuts against the one side of the workpiece (a). Then the rotation of the motor 5 is stopped by a proximity switch 15 in such an abutting condition. Thereafter, the cylinder 3 is extended to clamp the workpiece (a) without the workpiece being shifted by a large distance.

Title: Coding system and coding method
Inventor: HIRANAKA DAISUKE
IPC: H04N19/00
Filed: 1998-02-28
Abstract: PROBLEM TO BE SOLVED: To improve editing accuracy in image editing. SOLUTION: In a video signal consisting of intermingled telecine and non- telecine image signals, the telecine image signal is converted into an original video signal while the non-telecine image signal is coded with a fixed length without conversion. In this case, a preset fixed length processing period with respect to the video signal is sequentially detected. The frame pattern of the video signal in the fixed length processing period is detected and a fixed length processing unit to set fixed length processing is set in response to the number of frames when the video signal within the fixed length processing period is actually coded. Thus the number of fields of the video signal required for coding with the fixed length is made almost constant at all times, and a coding system and a coding method by which editing accuracy in image editing is enhanced are realized.

Title: Exposure device
Inventor: UGAI TAKESHI
IPC: G03G15/04
Filed: 1980-05-15
Abstract: PURPOSE:To perform the uniform exposure of an original surface or exposed surface, by controlling the luminous intensity of a light source by calculating the irregularity of initial exposure in the process of exposure by a photoelectric converter which detects illuminance. CONSTITUTION:Four light sources having discharge tubes 3 fitted at focal points of reflectors 4 are provided with electromagnets 5 which vary relative positions between arcs of the discharge tubes 3 and the reflectors 4. In the exposure area 2b of contact glass 2, a photoelectric converter 11 detecting illuminance is fitted. In this constitution, the moment the emitted energy of the discharge tube is triggered, it increases suddenly and decreases later, so the photoelectric converter 11 calculates the exposure up to time (t1). Then, a prescribed electric circuit stores previously the total quantity of light of the discharge tubes and the current of an exciting coil 6 is controlled on the basis of the stored value and initial exposure to equalize the total exposure, thus correcting the luminous intensity of the light sources. Consequently, exposure over the entire original surface is performed uniformly.
