Title: Method and apparatus for reading radiant ray picture
Inventor: TSUCHINO HISANORI
IPC: H04N1/04
Filed: 1986-05-23
Abstract: PURPOSE:To decrease unrequired radiant ray picture information and to decrease the reading time of a radiant ray picture by irradiating a radiant ray to a region designated in advance on a radiant ray picture conversion panel and using only an electric signal in the designated region as radiant ray picture information. CONSTITUTION:A radiant ray passing through an object 302 of an image pickup section 3A and irradiated to one region designated in advance in plural regions is absorbed by a radiant ray picture conversion panel 303, and a part of the energy is stored in a luminescent fluorescent body. The radiant ray picture conversion panel irradiated by one designated region of the image pickup section 3A is fed to a read section 3B. A read region control section 315 of the read section 3B based on the designated region information from a keyboard 316 gives a signal to an analog/digital converter 314 to control the sampling start position and the end position thereby designating the read region, at which the radiant ray picture information is obtained. The signal selected by the analog/digital converter 314 is fed to the radiant ray picture reproduction section, where the signal is visualized.

Filed: 1984-06-13
Abstract: PURPOSE:To obtain a fluororubber composition having good roll processability before vulcanization and excellent acid resistance and vulcanization characteristics, by incorporating a specified fluororubber mixture as a rubber component. CONSTITUTION:A fluororubber composition which contains a rubber component comprising 30-95wt% tetrafluoroethylene.propylene copolymer rubber (fluororubber I ) and 70-5wt% difluoroethylene.hexafluoropropylene copolymer rubber (fluororubber II) or difluoroethylene.hexafluoropropylene.tetrafluoroethylene terpolymer (fluororubber III). Additives such as carbon black, a peroxide, a softening agent, an antioxidant, and an age resistor each in a suitable amount are incorporated into the composition if necessary. If the amount of fluororubber II or III is less than 5wt%, the roll processability will not be improved; if above 70wt%, the tackiness to the roll will increase and thereby the processability will become worse.

Filed: 1982-07-14
Abstract: PURPOSE:To enable high-speed scanning with high efficiency without increasing the speed for deflecting light, by synthesizing the beams from the plural light sources differing in the polarization direction with a polarization beam splitter and scanning simultaneously plural scanning lines. CONSTITUTION:Lasers LD1, LD2 which are deflected respectively parallelly and perpendicularly to the plane of the figure are collimated by collimating lenses L1, L2 to parallel light which are made incident to a polarization beam splitter BS and are thereby synthesized. The laser LD2 transmitted through the splitter BS and the laser LD2 reflected by the same are deviated by an angle DELTAtheta=DELTAP/f (DELTAP is the pitch of scanning lines and (f) is the focal length of an ftheta lens) in this case. The synthesized light is reflected by a rotary polygonal mirror RM and is made into two scanning lines as it passes through the ftheta lens. A scanning plane 1 is scanned by said scanning lines. The same scanning speed as the speed obtained by doubling the number of revolutions of the mirror RM is thus obtd. Since the splitter BS is used for synthesizing the beams, the high efficiency is obtd.
