Title: Electron gun for microtron accelerator
Inventor: MIURA ICHIRO
IPC: H05H13/10
Filed: 1994-11-22
Abstract: PURPOSE: To keep the electron emitting face of a hot cathode constantly at the highest temperature and lessen thermal deterioration of a hot cathode supporting body by making a hot cathode supporting body possible to be fixed in both ends in the axial direction by radiating laser beam to the electron emitting face of the hot cathode constantly from the normal line of the electron emitting face. CONSTITUTION: Laser beam 6 from a main laser generating source 21 of an apparatus B which emits electron by heating a hot cathode 1 is radiated to a hot cathode 1 through a slit 4. The laser beam 6 is led and emitted to a laser beam emitting outlet 5 by a photo-transmission route. The emitted laser beam 6 passes the slit 4 and is radiated to the electron emitting face of the hot cathode 1 in a vacuum container. Due to the radiation of the laser beam 6, the electron emitting face of the hot cathode 1 can be heated to a desiring temperature. In this case, to heat efficiently and make the temperature for electron emission uniform, it is necessary to radiate the laser beam 6 in the normal line direction of the electron emitting face, which is a face to be radiated by the laser beam, of the hot cathode 1.  The laser beam emitting outlet 5 is thus set in the same plane as that of the circular track of the electron beam.

Title: Symbol recognizing device
Inventor: IWAMURA KAZUAKI
IPC: G06T7/00
Filed: 1987-12-11
Abstract: PURPOSE:To recognize a symbol even if disconnection of a symbol line, a partial omission, and connection to another line than the symbol are generated by allowing the title device to have a selecting function by using a symbol line tracking function and a segment estimating function for retrieving a segment end point in a search window area, and a recognition history. CONSTITUTION:In a tracking part 301, a search window of designated width is set to an end point of a segment by referring to a graphic data table 306, a retrieving part 305 is started and a feature point contained in the search window is retrieved by using a graphic retrieval table 307. When N pieces of end points are obtained by tracking the segment, a selecting part 302 is started and the segment being the most suitable for tracking is selected. When the end point of the segment does not exist in the search window, an estimation executing part 303 is started and the estimation of a symbol line is executed. When the first end point is retrieved again in the recognition process, a shape deciding part 304 is started and whether a circle symbol is constituted or not is decided. Since the device has a recognition history, even if an overlap is generated, it can be eliminated, and even if an omission exists, the estimation can be executed.

Abstract: PROBLEM TO BE SOLVED: To surely fix a structural member to a base material and show tensile force exceeding a limit by arranging an outer peripheral area extending toward an outer edge with a specified inclination angle in respect to a plane perpendicular to an axis of a through-hole for holding an engagement element. SOLUTION: An engagement part of an engagement element 11 is press-fitted into a base material 7 through a hole 19 of a structural member superposed on the base material 7 by an explosive applier. A fixation element 1 is mounted on the engagement element 11 together with a buffer element 17 and a pressing member 15. The pressing member 15 is turned connected along the engagement element 11. When the pressing member 15 is turned, tensile force is applied to the fixation element 1 which is then elastically deformed. An inclination angle W of an outer peripheral area 5 is decreased in respect to a plane perpendicular to an axis of a through-hole 2. The structural member 9 is fixed to the base material 7. When the tensile force exceeds a maximum allowable tensile force at a fixation point, the fixation element 1 is plastically deformed.  When the tensile force is decreased, a gap between a surface 10 and an outer edge 6 can be visually confirmed, for enabling sensing of an overload state at the fixation point.

Hereupon, a blower 25 is stopped and the motor 21 of an opening and closing valve 16 is operated on a valve opening side to guide the liquid accumulated in the temporary storage vessel 10 into an U-shaped tubular filter apparatus 13. In this case, since the liquid in the storage vessel 10 is in such a state that a heavy metal is sedimented, the heavy metal is adsorbed in a relatively efficient manner by the metal adsorbing filter material 16 such as the chelating resin in the filter apparatus 13. The frequency of this operation is counted by the counter 22.
