  • Patent number: 7680242
    Abstract: An X-ray examination apparatus includes a scanning X-ray source for outputting X-rays, a sensor base which is attached with a plurality of X-ray sensors and which rotates about a rotation axis, and an image acquiring control mechanism for controlling rotation angle of the sensor base and acquisition of image data from the X-ray sensors. With respect to each X-ray sensor, the scanning X-ray source moves the X-ray focal position of the X-ray source to each starting position of the X-ray emission set so that the X-ray transmits through a predetermined examination area of an examination target and enters each X-ray sensor, and emits the X-rays. The image control acquiring control mechanism acquires image data detected by the X-ray sensors, and a calculation unit reconstructs an image of the examination area based on the image data.

  • Patent number: 7522709
    Abstract: An X-ray examination apparatus changes a position of each X-ray sensor by rotating a sensor base, and resets a starting position of X-ray emission that becomes a X-ray focal position so that the X-ray enters each X-ray sensor after the position thereof is changed. A scanning X-ray source deflects an electron beam to easily change the position where the electron beam impinges a target of the X-ray source to an arbitrary location. The irradiating position of the electron beam then can be easily moved according to an accumulated irradiation time on the target. Therefore, maintenance can be performed without interrupting the X-ray examination.

  • Publication number: 20060208201
    Abstract: A neutralizing method and a neutralizing apparatus for effectively neutralizing an insulating member in a simple and efficient way are disclosed. A hard X-ray generating device radiates a hard X-ray on the obverse surface of the insulating member from the direction perpendicular to the obverse surface of the insulating member. The hard X-ray generating apparatus radiates a hard X-ray having the wavelength of not less than 0.05 ? but less than 1 ?. The hard X-ray ionizes the air on the obverse surface of the insulating member and neutralizes the charge on the obverse surface of the insulating member, while at the same time neutralizing the charge on the reverse surface of the insulating member by the X-ray transmitted through the insulating member.

  • Patent number: 5039847
    Abstract: Disclosed is an image processing apparatus capable of reading and processing both character data such as bar codes, optical readable letters and marks, and image data such as figures and tables by means of a single image scanner. The image processing apparatus has a parameter registration mode, a code addition mode and an image retrieval mode as operation modes. In the parameter registration mode, when a bar code corresponding to parameters related with image processing is read by the image scanner, a notification signal is outputted in response to completion of the reading. In the parameter registration mode, it is possible to determine priority to be assigned to either setting of the parameters through the image scanner or setting of the parameters through keys.

  • Patent number: 4733036
    Abstract: A key switch is disclosed which employs a coil spring formed of a spring element and which has a smaller-diameter portion, a conical portion joined to one end of the smaller-diameter portion, and a larger-diameter portion joined to the other end of the smaller-diameter portion. The smaller-diameter portion has the spring element coiled at a relatively small diameter. The conical portion has the spring element extending coiled so as to increase its diameter progressively toward an open end thereof. The larger-diameter portion has a diameter larger than the diameter of the smaller-diameter portion. The conical portion is maintained under compression and the small-diameter portion is maintained in proximity to a contact area by elements of the key switch to provide a linearly increasing depression force for the key switch.

  • Patent number: 4678880
    Abstract: A keyboard switch is provided which comprises a substrate on the upper surface of which a flexible switch is disposed that has paired fixed and movable contacts and includes a flexible sheet, guide posts passing through and secured to the substrate at mutually opposed positions on either side of the contacts, a key plunger fitted vertically movably in the guide posts, and a coil spring interposed between the key plunger and the substrate. The coil spring functions so that it pushes the flexible switch when compressed to cause the paired contacts to come into contact with each other and, when uncompressed, returns the key plunger to the initial position thereby to separate the paired contacts.
