Title: Radiotherapy apparatus
Inventor: SUZUKI TOSHINOBU
IPC: A61N5/10
Filed: 1987-06-17
Abstract: PURPOSE:To obtain the effect capable of realizing radiotherapy of every kind by one apparatus, by generating both of electron beam of relatively low energy and electron beam of relatively high energy. CONSTITUTION:The pulse generated from a pulse source 16 is sent to either one of a pulse transformer 14 and a pulse transformer 17 by a pulse change-over device 15. When the pulse is sent to the pulse transformer 14, electron beam is generated from the second electron gun 13 to be driven in an X-ray target 9. Since this electron beam is not accelerated by an accelerator, it is low energy one. The low energy X-rays generated by this low energy electron beam are allowed to irradiate the affected part while filtered by a filter 111. The high energy electron beam generated by the first electron gun 1 and an acceleration tube 3 is deflected by a deflecting electromagnet 8 to irradiate the target 9 and high energy X-rays are generated. In this case, the high energy electron beam is incident to the target 9 in an oblique direction but generates X-rays equivalently same to that in the case vertically incident to a target having the same thickness as that looked in said oblique incident direction.

Title: Image forming device
Inventor: UENO SUEO
IPC: B41J2/455
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To enhance image quality and reliability. SOLUTION: This image forming device 1 is constituted of a plane-parallel prism shifting the optical path of a light beam from a 2nd laser diode LP2 in parallel, a photodetector PD detecting the light beams from a 1st laser diode LD1 and the 2nd laser diode LP2 and outputting electric signals and an actuator 114 turning the plane-parallel prism as much as prescribed amount based on the electric signal generated based on the laser beam LB from the diode LP2 out of the electric signals from the photodetector PD. Therefore, since a mutual interval between two laser beams can be precisely set, the interval of image data exposed at a photoreceptor drum 22 is uniformized. Thus, the image quality is enhanced.

Title: Automatic taping device
Inventor: IWATA KAZUTOSHI
IPC: H01B13/08
Filed: 1981-09-25
Abstract: PURPOSE:To improve the working efficiency of taping, by providing a positional detector for  an insulation tape so that light emitting parts and light receiving parts as one unit are controlled by a driving mechanism for the light emitting parts and the light receiving parts,  while they are maintained at a predetermined distance to the insulation tape. CONSTITUTION:A light emitting part 19 and a light receiving part 22 in a positional detector  23 for a tape are attached in one movable part 21. The intencity of lighting of the light receiving part 22 is maintained constant if light emitting current is controlled in accordance  with the rotational position of a rotary ring 11. Such photoelectric elements which are arranged by a number of 2 or 3 in the vicinity of the center position of the tape and by a number of 2 or 3 in the peripheries of both side ends of the tape, are energized so that a slip of  the tape may be detected with a high accuracy. When any slip of the tape arise, a guide  roller 13 is propmtly moved for preventing the slip. Further, a tape breakage is detected by  the photoelectric elements at the center of the tape, and therefore, alarm is issued by an arithmetic control unit 17. Simultaneously, the light emitting parts 34 on the rotary ring 11, for informing abnormality, are lit on and a plurality of light receiving parts 33 on a carrier bed 32  successively receive light so that deceleration and stopping are brought about in this order.  Accordingly, the work of taping may be automatically carried out and therefore, the working efficiency of taping is improved.

IPC: H04N5/7826
Filed: 1979-11-22
Abstract: PURPOSE: To realize a steady and accurate tracking, by giving a parallel shift to the head through the deformation of a pair of plate springs.  
     CONSTITUTION: When the motor rotates in accordance with the detection output of the track shift, the pinion 30 has a unified rotation to give a rotary movement to the driving arm 26 incorporating the sector tooth 27. As a result, the arm 32 which is born by a pair of plate springs 14 and 15 between holding members 17 and 18 has a parallel shift to give a unified parallel shift to the record/reproduction head 7. With this smooth parallel shift, no change is caused to the contact state between the head 7 and the magnetic tape. As a result, a steady and accurate tracking control is secured.

Title: Fluorescent lamp
Inventor: AKEBOSHI MINORU
IPC: H01J61/28
Filed: 1990-06-11
Abstract: PURPOSE:To maintain an optimum and stable light flux level at all times by forming a temp. gradient in the neighborhood of the melting point of amalgam as extending in the longitudinal direction of an amalgam accommodation part, and arranging amalgam in the accommodation part so as to be continuous alongside this temp. gradient. CONSTITUTION:Amalgam 11 is adhered to the inner surface of a glass thin tube 10 wide spreadly and continuously. The ambient temp. of the amalgam 11 is largely influenced by the heat from an electrode 9, and a high temp. part 11H is formed in the amalgam portion near this electrode 9 while a low temp. part 11L is formed in the amalgam portion remote from the electrode 9. In steady lighting, for ex., at an atmospheric temp. of 25 deg.C, the high temp. part 11H shall be at 102 deg.C while the low temp. part 11L at 92 deg.C, the temp. difference being 10 deg.C. Setting of temp. difference being possible in this manner at a short amalgam distance is because the amalgam 11 is put widely in close contact with the inner surface of the glass thin tube 10, and the heat radiating effect of the tube 10 is greatly reflected in proportion to the thermal conductivity of the amalgam 11 alloy. As a result, the Hg vapor pressure of the lamp concerned is restricted with its lowest value.

Abstract: PURPOSE:To obtain a direction detecting apparatus which does not work erroneously to the change of input signals. CONSTITUTION:A first signal delay means 11 outputs a pulse signal b1 obtained by inverting the level of a pulse signal (b). A trigger signal (f) for latching the level of the pulse signal (b) and pulse signal b1 is generated by a second signal delay means 12, pulse signal shaping means 13, 14, 15, a set signal generating means 16, a reset signal generating means 17 and a trigger signal generating means 18, and output to latch means 19, 20. The latch means 19, 20 latch the level of the pulse signal (b) and the pulse signal b1 when the trigger signal (f) is input thereto, and outputs the respective levels to output sides C, D. In this manner, since the level of each of the pulse signal (b) and the inverted pulse signal b1 is latched by the trigger signal (f), the apparatus is prevented from erroneously operating even if tone input signals (a), (b) are changed.
