Title: Laying method for self-supporting type optical cable
Inventor: TAKEHARA HIDEOMI
IPC: G02B6/46
Filed: 1985-05-15
Abstract: PURPOSE:To remove residual distortion and to prevent a core from movement by previously applying prescribed times or more the tensile force obtained at the time of stringing to a suspension wire part and anchoring the suspension wire part on an electric pole or the like with prescribed tensile force to suppress the movement of an optical cable core part in the longitudinal direction. CONSTITUTION:Before anchoring the optical cable, an excessive tensile force, e.g. twice or more the tensile force obtained at the time of stringing, more than the tensile force of the stringing is applied to the suspension wire 23. A housing 22 is drawn out together with the suspension wire 23 and an optical cable core 21 is drawn into the housing 22 by a moving distance l1 from the initial state of (A) to the state shown in (B). When the tensile force applied to the suspension wire 23 is temporalily released, the optical cable core 21 tries to restore to the original state, but the core 21 is not restored to the initial state and shifted as shown in (C), so that the quantity l2 of distortion release is lefted. Thus, the residual distortion is removed by connecting the optical cable to a connection part after treating the optical cable, improving the reliabil ity of the optical fiber core due to the movement of the optical cable core.

Title: Overlap separating device for fluoroscopic image
Inventor: NUMAGAMI HIDEO
IPC: G06K9/36
Filed: 1984-05-24
Abstract: PURPOSE:To decrease the wrong decision rate of object inspection by providing a density histogram measuring means for a gradational image, a means which decides an overlap of objects with a function for evaluating an overlap from a degree of dispersion, and a means which separates overlapping fluoroscopic images on the basis of a determined threshold value. CONSTITUTION:An object 2 of inspection is irradiated with X rays from an X- ray generating device 1 for fluoroscopy, and its fluoroscopic image data is detected by an X-ray detector 3 and converted by an A/D converter 4 into a discrete electric signal, which is inputted to an image memory 6. Then, a density histogram is calculated as to the fluoroscopic image inputted to the memory 6 by using an image processing part 7. Then, the dispersion V of the density histogram is calculated. This dispersion V is compared with the predetermined threshold value V0 and it is decided that there is no overlap when V<V0 or an overlap when V>=V0. Then, the overlap density image is separated into a part above the threshold value and a part below the threshold value. Then, those two images are outputted and displayed on a display part.

Title: Image processor
Inventor: YANAGIDA AKIKO
IPC: A61B6/03
Filed: 1995-04-27
Abstract: PURPOSE: To properly display a differential processing image by deciding the propriety of the positioning processing when the differential processing image is produced. CONSTITUTION: The anatomical structure of a lung, etc., are extracted out of a differential image or an original image (S11), and at least one partial area is set based on the extracted anatomical structure (S12). Then the value showing the distributional spead of image data included in the set partial area is calculated as the feature value of the differential image (S13). When the distribution spread of image data exceeds the threshold value, the positioning processing is improper and therefore the occurrence of a false image is decided (S14). Thus the display is canceled for the differential image or its partial area where the improper positioning processing is decided.

Abstract: PURPOSE:To obtain a small-sized inexpensive printer having high print quality by directly fixing an image from a photosensitive body by a pressure and not only preventing toner drop and scattering to obtain prints of good quality but also simplifying the printing process and shortening the carrying length. CONSTITUTION:A photosensitive body 5 which is set to the neutral state by destaticization due to an erase lamp 2 after having a remaining toner removed from the peripheral surface by a cleaner is uniformly electrified by a charging charger 3, and print information is optically written on the photosensitive drum 5 by an LED array 4. The toner is supplied to the peripheral surface of the photosensitive body 5, where information is written, by a magnet roll in a developing device 6 to develop a latent image to a visible image. A pickup roll 7 synchronized with rotation of the photosensitive drum 5 sends out a print form, and the toner on the photosensitive drum 5 is transferred to the print form when it passes a transfer charger 13. Thereafter, the toner on the print form is fixed by the pressure between a pressure fixing roll 15 and the photosensitive drum 5, and the print form is stacked in a stacker 9 through an ejecting roll 10.

Inventor: HASEGAWA ATSUSHI
IPC: H01L31/04
Filed: 1995-04-27
Abstract: PURPOSE: To increase the transmittance of light and to increase the condensing ratio of a solar cell module by a method wherein a surface treatment is performed on the surface on the side of light input of a protective sheet and geometric irregularities are formed in and on the surface. CONSTITUTION: A protective sheet 10 has geometric irregularities 11 (recessed parts 11a and projected parts 11b) formed innumerably in and on the surface on the side of light input by performing a surface treatment on the surface. When a sunlight H strikes on the surface of the sheet 10, the most part of the sunlight is transmitted the sheet 10 intact and some percent of the remnant results in reflecting, but some percent of the reflected light further repeats reflection in the recessed parts 11a of the geometric irregularities 11 in and on the surface and each time of the reflection, some percent of light is transmitted in the interior of the sheet 10. Thereby, by repeating the reflection, the transmission amount of the overall light results in being increased and the condensing ratio of a solar cell module 1A can be increased.  Owing to this, a generated energy per unit module is increased.

Filed: 1992-03-31
Abstract: PURPOSE:To switch the communicated state of air seal vent holes to an exhaust port switchable in response to the action of a selector valve controlled according to the exhaust pressure and use a vacuum pump only as the vacuum pump or concurrently utilize the functions of the vacuum pump and a blower. CONSTITUTION:When a vacuum pump l is used only as the vacuum pump 1, the pressure of an exhaust port 3 side is low due to its communication with the atmospheric air, and a selector valve 6 is opened by the spring force. Some positive pressure generated by the pipeline resistance of an exhaust path 9 is applied to air seal vent holes 10, 11, and the infiltration of a lubricant into a rotor operation chamber is prevented. When the functions of the vacuum pump 1 and a blower are concurrently utilized, a valve 15 is closed, the exhaust path 9 is communicated with a tank 14, and the pump exhaust side pressure is gradually increased. When the selector valve 6 is closed, the pressure gas on the exhaust side is fed to the air seal vent holes 10, 11 via an orifice 19, and the infiltration of the lubricant into the rotor operation chamber is likewise prevented.

Title: Method for controlling sectional profile of sheet in cold rolling of thin sheet
Inventor: FUJITA FUMIO
IPC: B21B37/40
Filed: 1986-05-07
Abstract: PURPOSE:To obtain a sectional profile which is nearly rectangular by changing the overlap quantity of the tapered parts of work rolls onto the ends of a sheet so as to meet the region where the sheet thickness distribution can be changed by the sheet thickness, thereby controlling the sectional profile of the sheet. CONSTITUTION:The work rolls of a rolling mill have the straight tapered parts at one end of the body length. Such work rolls are disposed point symmetrically above and below and are shifted in opposite directions. The sectional profile of the sheet is controlled in this case by changing the overlap quantity of the tapered parts on the ends of the sheet so as to meet the region where the sheet thickness distribution can be varied by the sheet thickness for each of rolling passes or stands. More specifically, the shift quantity of the work rolls is in creased in the front stage where the sheet thickness is large, i.e., the overlap quantity of the tapered parts on the sheet ends is increased and the overlap quantity is successively decreased in the rear stage in the case of rolling with the multi-stands rolling mill or rolling of several passes with single stand. The sectional profile of the sheet is thereby effectively controlled.
