Title: Method and device for x-ray photographing
Inventor: TSUTSUI HIROSHI
IPC: H05G1/30
Filed: 1992-02-06
Abstract: PURPOSE:To keep constant the calculation accuracy in X-ray image processing at all times despite varying thickness of the object to be photographed. CONSTITUTION:Prior to measuring an object to be photographed, an X-ray sensor 2 senses the intensity of the X-rays from an X-ray generator 1 transmitted through a phantom 6 in step form whose thickness varies in steps having the same X-ray absorption coefficient as the object. A control part 4 changes the tube current impressed to the X-ray generator 1 or the sampling time of the sensor so that the intensity of the transmitted X-rays is equal in any place across the thickness of the phantom 6 to determine the optimum X-ray irradiation conditions for the value of phantom thickness, and the result is stored in memory. To photograph the object, its thickness is measured and entered, and thereby the phantom thickness nearest the thickness of the object is selected. Thereby the pre-measured optimum conditions are selected to serve photographing of the object with the optimum S/N for quantitative measurement of the X-ray image, and accurate measuring is conducted despite varying thickness of the object.

IPC: G06F3/12
Filed: 1992-01-09
Abstract: PURPOSE:To increase capacity for supplying paper and to increase the kinds of paper sheets to be supplied. CONSTITUTION:A printer A judges the presence/absence of paper sheets in the own printer and the kind of paper sheets or the like in response to the input of printing data from a host device 12 to an input port 2. When it is judged by this judged result that the printing data can not be printed by the own printer, the printing data are transmitted from an output port 4 to a printer B in the next step. When it is judged according to the judged result that the printing data can be printed at the own printer, the printing data are printed on the paper sheets in the own printer. Even in the printer B the similar processing is executed as well concerning a printer C. Thus, the capacity for supplying paper sheets can be increased on the side of the host device 12, and the kinds of paper sheets to be supplied such as B4, A3, B5, A4 and postcard size, etc., can be increased.

Abstract: PURPOSE:To keep the focusing state even if the intensity distribution is ununiformed due to diffraction effect by pits or control band noise is generated due to a returned light by detecting that a differential output is zero from a split photodetector to which no light spot is contacted so as to detect the focusing state. CONSTITUTION:The photodetector 8 is arranged at a position a spot of a reflected light forms just a circle between a focal point of lenses 7a, 7c and a focal point of lenses 7b, 7d at the focusing state where a disc 5 is coincident with the focal position of an objective lens 4. That is, a least circle of confusion 9 exists within a plane vertical to an optical axis 12 between a focal point 11 of the sectioned lenses 7a, 7c and a focal point 10 of the sectioned lenses 7b, 7d. Since no light is contacted to photodetectors 8b-8d by making a diameter of the least circle of confusion 9 coincident with the diameter of the photodetector 8a at focusing, each output is zero.

IPC: F16F13/00
Filed: 1987-01-30
Abstract: PURPOSE:To enhance the vibration isolating effect and heighten the degree of safety during transportation, by arranging through pressure application a vibration resisting member between a coil spring and a vibration resisting bed and putting highly viscous fluid, which dips the lower part of the vibration resisting bed below the fluid surface, into a vessel together with providing a sealing means which prevents the fluid from leaking. CONSTITUTION:A vibration resisting member 4 is arranged through pressure application between a coil spring 3 and a vibration resisting bed 2. Highly viscous fluid 5 is stored in a vessel 1 to a degree that the fluid 5 dips the lower part of the vibration resisting bed 2 below the fluid surface, while sealing means 11 and 13, which prevents the fluid 5 from leaking, are provided. Thus, the main vibration preventing function is performed by the coil spring 3, thereby lowering the natural frequency in both vertical and horizontal directions. Meanwhile, both unstability or a resonance phenomenon, which is caused by the natural frequency lowered by the coil spring 3, is absorbed by the highly viscous fluid 5, thereby enhancing the damping force. Since a sealing means consisting of a ring groove 11 and a ring part 13 is provided, this vibration isolator remains safe even during transportation.

Filed: 1996-02-07
Abstract: PROBLEM TO BE SOLVED: To enable more plural color expression by using the same recording color for every designated area as either one of plural colors in a device capable of being recorded with plural colors. SOLUTION: A color board 236 inputs two kinds of picture data 3821 and 3822 obtained by reading an original to a color separating and judging part 391 so as to execute the color discrimination of respective picture elements. A marker flag generating part 395 recognized a marking place in the original and an area recognizing part 412 recognizes a rectangular area by the place. A color density correcting part 418 permits a recording density concerning the same recording color to have difference in the inside and the outside of the rectangle. The color board output signal 419 is transmitted to a recording part with a succeeding stage circuit and the density of one specified color (red, for example) within the two color recording of red and black, for example, is discriminated inside and outside the area. Thus, the plural areas read by the same color are discriminated by the densities.

Title: Heat accumulator
Inventor: KASHIMA KOJI
IPC: F28D20/02
Filed: 1987-01-31
Abstract: PURPOSE:To make it possible to release the heat accumulating material of super- cooling without accompanying deterioration by cooling a latent heat accumulating material locally down to below the limit temperature of its super-cooling. CONSTITUTION:If, with a switch 6 closed and an electric heater 6 energized, a latent heat accumulating material 4 is heated through a vessel 2 up to a temperature over the phase change temperature and then it is left as it is, the heat accumulating material 4 is kept at a temperature that is higher than the limit temperature of super-cooling by a heat insulation layer 3, and holds its latent heat in the state of super-cooling. Next, when a switch 15 is closed and an electronic cooling element 9 is energized, the temperature of a cooling section 11 drops and the section which is in contact with the end section 12 of the heat accumulating material 4 is locally cooled by the end 12 of the cooling section. In this case if the temperature of cooling of the heat accumulating material 4 is brought down to below the limit temperature of the super- cooling, the state of super-cooling is removed and it solidifies. And, this action is extended to the whole of the heat accumulating material 4 to cause it to release the heat that is held. A switch 16 is opened right after the super-cooling of the heat accumulating is locally released, and the cooling of the heat accumulating material by an electronic element 9 is stopped.
