Title: X-ray tube device
Inventor: ONO KATSUHIRO
IPC: H01J35/06
Filed: 1987-12-02
Abstract: PURPOSE:To obtain an X-ray focus point of an even intensity distribution and a sufficient X-ray intensity by specifying the shape of a cathode filament. CONSTITUTION:This X-ray tube device has a plate-type cathode filament 301 which consists of a thermion releasing member 301a formed vertical to the electron beam axis and getting a high temperature, U-shaped or V-shaped legs 301b bent vertical to the thermion releasing member 301a and bent back to the inner sides, and fixing members 301c which are fixed to filament holders 302. Since the thermion releasing member 301a is a flat plate, the releasing directions are all same, the focus property of thermions is good, and an X-ray focus with an even electron intensity distribution can be obtained. Moreover, even when the thermion releasing member 301a gets a high temperature, the thermal expansion of the legs 301b is absorbed, making very little variation of the positions. As a result, the scope of focus can be suppressed narrow, the allowable input power is increased, an X-ray focus with an even electron intensity distribution is obtained, and the resolution of X-ray image can be improved.

Title: Video reproducing device
Inventor: AOYANAGI SANAE
IPC: G09G5/377
Filed: 1994-11-16
Abstract: PURPOSE: To provide the video reproducing device which can suppress outrunning as much as possible even when the period of the writing of video data to a subordinate screen becomes long. CONSTITUTION: The video reproducing device is equipped with a video memory 3 and a buffer memory 1 which hold video data and a data transfer means 2 which writes the video data held by the buffer memory in the video memory, and writes video data of another picture held in the buffer memory 1 in a partial area of the video memory 3 holding the video data of one picture, reads video data of the composite picture out of the video memory 3, and reproduces it. A data transfer means 2 starts writing the video data of the former picture right after the video data held in the partial area of the video memory 3 is read out.  Even if the write period extends almost to twice as long as the read period, the writing is started before the start of the read period without waiting for the read period to end, so the writing can be completed before the read period of the subordinate screen starts, thereby preventing the outrunning.

Title: Spread spectrum modulation and demodulation system
Inventor: ISHIGAKI YUKINOBU
IPC: H04B1/7107
Filed: 1989-11-25
Abstract: PURPOSE:To remove an interference wave and noises in a spread spectrum signal on a demodulation side by imposing spread modulation on an input signal and outputting a spread spectrum signal from a modulation part, and receiving it by a demodulation part and making a reverse spectrum spread with spread codes. CONSTITUTION:The reverse spread circuit part 17 of the demodulation part multiplies the spread spectrum signal a from an input terminal In5 by the spread codes P from a terminal In6 through a multiplier 3 and makes the reverse spread to obtain a signal b. The signal b is passed through an HPF 21 to remove a demodulated information signal and part of a spread disturbing wave is also removed to obtain a signal c. A multiplier 4 multiplies the signal c by the codes P to demodulate the interference wave and then a leaked component which is not demodulated is generated, but this component has negative energy, so this is considered to be spread, thereby obtaining a signal d. This signal d is passed through an HPF 22 to reduce the leaked component to half and obtain a signal d, which is further multiplied by the codes P through a multiplier 5 to demodulate the negative energy, thereby obtaining a signal i. Then the signal i is amplified and added to the signal b and the composite signal is passed through an LPF 13 to remove the interference wave, thereby obtaining an information signal D at an output terminal Out2.

Abstract: PURPOSE:To enable fine angle control for relatively wide angle measuring range. CONSTITUTION:To the rotation shaft 24 of a goniometer, an arm 26 is fixed and at the tip of the arm 26, an arc surface 28 is formed. The center of the arc surface 28 coincides with the center of the rotation shaft 24. On the arc surface 28, wire 30 is wound and one end of the wire 30 is fixed with a fixing device 32 to the arm 26 and the other end is fixed to the spindle 36 of a micrometer 34. To the side surface 40 of the arm 26, a hook 42 is fixed and to this hook 42, a coil spring device 44 is connected. The moving distance (x) of the spindle 36 is completely proportional to the rotation angle of the arm 26. Therefore, compared with the conventional tangent bar method and the sine bar method micro rotation goniometer, angle measurement error accompanied by the arm rotation does not exist and thus, angle control without error for relatively wide angle measuring control becomes possible.
