Title: X-ray fluoro-radiographic equipment
Inventor: TAKAHASHI FUMITAKA
IPC: H04N7/18
Filed: 1991-03-19
Abstract: PURPOSE:To remarkably reduce the exposure quantity at the time of group medical examination by constituting the device of a fluoroscopic X-ray filter part consisting of a filter part or a non-filter part, a viewing X-ray filter part consisting of a filter part in which a decreasing/weakening factor of X-ray energy is high, and an X-ray filter part driving device. CONSTITUTION:At the time of fluoroscopy, instance, an aluminum plate of 3mm thick is used as a fluoroscopic X-ray filter part 10b, and when it is placed in a position for covering an X-ray radition port 1a, a soft radiation of low energy can be eliminated, comparing with the time when it is not place, and the surface exposure of a body 2 to be examined can be reduced. By eliminating the soft radiation of low energy, the quality of radiation becomes hard, and the contrast of an image falls, but it is sufficient for the confirmation of the photographing part being a main purpose of fluoroscopy. On the other hand, at the time of photographing, photographing is executed by moving the fluoroscopic X-ray filter part 10b. In such a way, the soft radiation of low energy is not eliminated, and an image having contrast can be obtained. The exposure quantity in this case becomes more than the case when there is the aluminum plate, but its quantity is the same as the time of photographing by a conventional device.

Title: Brushless motor
Inventor: SUZUKI YASUO
IPC: H02K29/08
Filed: 1985-03-18
Abstract: PURPOSE:To reduce the size and the weight by displacing a pair of stator poles disposed at both ends of a coil of a rotor side at different widths, thereby self-starting to rotate. CONSTITUTION:A rotor 1 of an outer rotor type brushless motor is composed of cylindrical and disc-shaped stator cores 2, 3 and a coil 4. The core 2 is formed with the first stator pole 9 suspended axially inward from the edge, integrally formed in the width of 150-180 deg., and magnetic detecting means 11 is provided near a hole 8. The second stator pole 14 is stood similarly at the core 3, and provided at the position displaced at 200-225 deg. of rotating direction in the half width of the first stator pole 9. Further, the output shaft 21 of a permanent magnet rotor 20is supported through a bearing 19 at a mount 22. Thus, since the stable position at deenergizing time is displaced in the rotating direction from the stable position of the rotor 20 at energizing time, self- starting property is obtained to shorten the axial length.

Title: End-face treatment of hollow yarn membrane separation module
Inventor: NAKAGOME KEISUKE
IPC: B01D63/02
Filed: 1983-03-29
Abstract: PURPOSE:To repair the leak parts by pressing a repair material, which is prepared by coating a casting resin for repairing on the surface of a foam material in a strippable state, on the casting resin end face on the opening side of a hollow yarn membrane of the hollow yarn membrane separation module wherein both end parts are bonded and fixed with the casting resin. CONSTITUTION:A repair material is prepared by providing a uniform layer of a casting resin for repairing such as an epoxy resin or a urethane resin on the surface of a foam material consisting of rubber or a synthetic resin in a strippable state. When the repair material is pressed on the casting resin surface on the opening side of the hollow yarn membrane of the module, the casting resin for repairing is stripped from the surface of the foam material and transferred to the above-mentioned end face to fill the improperly bonded parts. Meanwhile, as the casting resin for repairing is kept out of contact and retained by the foam material at the opening part of the hollow yarn membrane, the intrusion of the resin into the opening part can be prevented.

Filed: 1988-03-10
Abstract: PURPOSE:To attain add-registration of a translating word by substituting the translating word based on the registering information of a learning table for a word and translating it with a translating means after storing and registering the learning table to register the output information of a post editing supporting part, a translating word selecting part, etc. on the word. CONSTITUTION:When an add-registering to a learning table by a translating word selecting part 9a ends, the effect is notified to a configuration element generating processing part 8a. As a result, at the configuration element generating processing part 8a, an output translating word is decided with referring to a learning table 9b to a parallel nodal point, and a configuration element generating processing is executed again. A translated result is displayed in the upper half area of the display scope of a display device 2 through a post editing supporting part 5 and an operational control part 3. Thus, a compromise dictionary register (add-registering) is attained without breaking a translation processing once.

Title: Thermal recording
Inventor: MOCHIZUKI HIDEHIRO
IPC: B41J29/00
Filed: 1989-03-09
Abstract: PURPOSE:To form an image free from color tone turbidity and a ghost by using a recording sheet any number of times and thermally treating the recording sheet prior to its next use, when the sheet is used a plural number of times. CONSTITUTION:The ink layer of a recording sheet 5 and a reversibly transferable dye absorbing member are superposed in such a manner as to allow these to come in contact with each other. Then the sheet 5 is heated from the rear (substrate film side 2) using a heating roller 1 so that the reversibly transferable dye on the surface of an ink layer 3 is absorbed into an absorbing member 4 and part of the dye is allowed to diffuse in the recording sheet. The sublimable dye of different color attaching to the surface of the recording sheet sublimates and dissiplates due to the thermal treatment of the sheet following the reversible transfer. Or the sublimable dye diffuses in the interior of the ink layer. Consequently the image formed in the transfer process after thermal treatment is not adversely affected. Thus it is possible to reduce the effect of the reversible transfer and prevent generation of color tone turbidity and the appearance of the ghost of the previous pattern.

Timing discriminating circuits TDT1 and TDT2 detect the three-bit timing discrimination code in the arrival transmitted signal sequence, and detect its value. For the switching of site diversity, the value of the timing discrimination code is specified and control is so exercised that an global station A starts transmission at a signal following the transmitted signal whose transmission is interrupted by an global station B.
