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.

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.

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.

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.

Abstract: An input apparatus for computers is interposed between a keyboard and the computer. This apparatus comprises: an area designating device on which a desired visible information sheet having predetermined visible information can be disposed and which outputs a designation area signal indicative of the designated area of the visible information; a receiver to receive registration data comprising the area of the visible information and the key code of one or a series of plurality of keys corresponding to this area, the registration data being sent from an external system; a registering memory to store the registration data received by the receiver; a data fetching circuit to take out the corresponding key code from the registering memory by reference to the registration data in response to the designation area signal which is given from the area designating device; and a transmitter to transmit the fetched key code to the computer.

Abstract: In this coordinate inputting system, a coordinate inputting sheet is provided for detecting an axial coordinate, and this includes a sheet body with a resistive surface laid over one of its sides, a pair of mutually substantially parallel edge electrodes extending along opposite edges of this resistive surface which are for having voltage applied between them, and several intermediate electrodes, substantially mutually parallel and substantially parallel to the pair of edge electrodes, and extending along the resistive surface bewteen the pair of edge electrodes in a mutually spaced relationship.

Abstract: In this coordinate inputting sheet, there are provided an X coordinate inputting sheet for detecting an X coordinate and a Y coordinate inputting sheet for detecting a Y coordinate. These X coordinate and Y coordinate inputting sheets are laid together with their conducting surfaces mutually confronting one another. An insulating projection is provided between the X coordinate inputting sheet and the Y coordinate inputting sheet in order to space apart their opposing conducting surfaces. Auxiliary electrodes extend substantially along equipotential directions of at least one of the X and Y coordinate inputting sheets adjacent to the insulating projection.

The auxiliary electrode is used to either measure a voltage at its respective position which can be used to correct point contact data generated by said sheet or to apply a voltage to said sheet so that point data generated by said sheet is correct.

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.
