Title: X-ray ct picture processor
Inventor: YOSHITOME EIJI
IPC: G16H10/60
Filed: 1984-05-31
Abstract: PURPOSE:To attain simple beam hardening correction of a bone by contracting a binary picture and a weight function indicating the bone by 1/N in the vertical and horizontal directions, repeating two-dimensional addition of the weight function by using the binary picture as its mask in all picture elements, then expanding the interpolation again by N times to add the expanded result to the original density image. CONSTITUTION:An X-ray CT reconstituted density image inputted from an external device to the 1st picture memory 1 is converted by a binary-coding device 2 and the converted result is stored in the 2nd picture memory 3. A masking adder 5 matches the center of the weight function obtained from a weight function memory 4 with a picture element position indicating the bone in the binary picture are having a high CT value to add and store the two-dimensionally expanded weight function to/in the 3rd picture memory 6. The picture obtained by repeatedly adding all the picture elements is added to the initially inputted reconstituted density image by a picture adder 7 and the beam hardening artifact of the bone is removed. Thus, the number of times of operation is reduced and rapid operation is attained by contracting the binary picture and the weight function indicating the bone by 1/N in the vertical and horizontal directions.

Filed: 1992-04-30
Abstract: PURPOSE:To secure the nip of a developing roller with a photosensitive drum at a required value and to miniaturize the whole of a device by loading a specified electrical conductive rubber roller on the outside circumference of the shaft of the developing roller and forming the diameter thereof to be equal to or under a specified diameter. CONSTITUTION:A developing unit 16 is obtained by arranging the developing roller 20, a toner layer forming blade 21 and a toner supply roller 32 in a developing unit housing 31, and non-magnetic toner 19 being developer is held inside. The roller 20 among them is obtained by loading the electrical conductive rubber roller on the outside circumference if the shaft and forming the diameter thereof to be <=16mm. When the radius of the electrical conductive rubber roller is set to be RD and the thickness of a rubber layer constituting the electrical conductive rubber roller is set to be (h), the condition of 1<=h<=1.2RD-3 {a unit is (mm)} is satisfied. Therefore, the nip of the roller 20 does not become under required width even when the shaft of the roller 20 is bent. Besides, a hindrance does not occur even when the diameter of the roller 20 is formed to be <=16mm. Moreover, since the pressing force of the roller 20 can be set low, load torque can be made small and the device is minuaturized.

Filed: 1987-05-08
Abstract: PURPOSE:To equalize the contrast of the whole screen by performing a transmission surface treatment to a heat spot generating part of a polarizing plate of an incident side. CONSTITUTION:A reflection preventive layer 4 is formed by performing a trans mission surface treatment to a part where a heat spot is generated, namely, to the inside of a circular contour region A. That is, as for the part in the circular contour region A, the surface treatment is executed so as to decrease the intensity of a reflected light. As for such a reflection preventive layer 4, for instance, by a vapor-depositing method or a coating method, it will suffice that a transparent dielectric layer is formed under a relation of (nd)=lambda/4 (pro vided that nd and lambda denote a refractive index of the transparent dielectric layer, and wavelength of an irradiated light, respectively). As for such a transpar ent dielectric body, magnesium fluoride is available. In such a way, an easily visible image display in a state that the contrast of the whole screen picture has been equalized is obtained.

Title: Method and apparatus for measuring taste degree of rice
Inventor: SAIGA KEIJI
IPC: G01N21/57
Filed: 1989-05-02
Abstract: PURPOSE:To make it possible to measure the taste of rice accurately and objectively by projecting light rays on boiled rice to be measured, reflecting the light rays, provid ing a polarizing filter in the light path of the light rays, and judging the gloss of the rice. CONSTITUTION:The light emitted from a light source 3 is inputted on the surface of a boiled rice A through a diffusing plate 4 and reflected. Of the reflected light, the reflected light from the surface of a water holding film becomes the polarized light. The light, which is transmitted through the water holding film and diffused and reflected from the surface of the rice, becomes the non-polarized light. The reflected light wherein the polarized light and the non-polarized light are overlapped passes a polarizing filter 5. The filter 5 passes only the component whose optical axis is in parallel with the optical axis of the filter among the components of the arrived light. The component which is orthogonal to the optical axis of the filter is shielded. Therefore, the component of the passed light (or the shielded light) can be controlled by turning the filter 5 and changing the angle of the optical axis. The light which has passed through the filter 5 reaches a photodetector 8 through a convex lens 7, and the amount of the light is measured. The light from the photodetector 8 is sent to a display device 9 and converted into the numerical value, and the result is displayed.
