Title: Horizontal synchronizing period contour emphasis elimination circuit for video signal
Inventor: RI DOUBUN
IPC: H04N5/208
Filed: 1989-09-14
Abstract: PURPOSE:To eliminate a contour emphasis part in a horizontal synchronizing component smoothly by eliminating a horizontal synchronization component of an input video signal less than a pedestal level with a horizontal synchronization component elimination circuit before the input video signal is inputted to a contour emphasis circuit. CONSTITUTION:A horizontal synchronization component elimination circuit 10 eliminates a horizontal synchronization component (a) in an input video signal SVO less than a pedestal level to output a video signal SVO' and it is fed to a delay circuit 1 and an adder 3 being components of a contour emphasis circuit 11. An adder 13 adds a contour emphasis signal SV5 outputted from a subtractor 5 being a component of the contour emphasis circuit 11 and a video signal SV1' outputted from a delay circuit 12 and outputs a contour emphasis video signal SV7. Thus, a waveform in which preshoot and overshoot are added in the vicinity of the contour of the video signal SV1' except the vicinity of a leading part (b) and a trailing part (c) of a horizontal synchronization component (a) of the video signal SV1' is outputted.

IPC: H04N1/00
Filed: 1984-11-13
Abstract: PURPOSE:To obtain a device responsive to fast conversation such as a TV conference by transmitting a document in a short time through a narrow band transmission line, displaying the document roughly once to display the outline of throughs or a graph required for explanation and switching the display sequentially into a high definition picture display succeedingly. CONSTITUTION:In transmitting the image of information in a temporary memory 2 to the reception side at first while an average contrast in the unit of, e.g., 1mm<2> is converted to logical level 1/0, the image is stored in a memory 13 while being restored to a normal pattern via a receiver 9 and a signal converter 11, and stored in a high-speed read memory 13' while the input 1 dot is used as dot information of 8X8=64. The said picture information is read by a high-speed scanner 14 in a scanning line speed of a television picture and displayed on a high definition projector as a rough graph. Then a control device 5 at the transmission side transis to high- definition scanning and the information is transmitted in the normal mode. In receiving the information, a rough/normal information receiver 10 switched the temporary memory 13 and rewrites the memory 13' into new information sequentially. Since a high speed scanner 14 applies scanning as a TV picture even during this time, the picture in the high definition projector 15 is replaced in the picture sequentially from the rough mode to the high definition mode.

Title: Pump impeller for preventing sticking of scale
Inventor: YAE SHIGEKI
IPC: F04D29/30
Filed: 1994-10-04
Abstract: PURPOSE: To save a power consumption during operation of a pump, and make it possible to operate it stably for a long time. CONSTITUTION: If Chromium plating is carried out on a pump impeller, electric potential of chromium and magnetite Fe3 O4 and hematite Fe2 O3 which are the main component of a scale becomes nearly same, an electric potential difference is not generated, and electric chemical sticking (electrolyte sticking) is not generated. Since absorption of hydrogen is remarkably in chrome plating, the problem of hydrogen embrittlement causes, fatigue strength of a base material is reduced, and those problems are not good.  At this point, in an impeller for preventing sticking of the scale, chrome(Cr) plating is carried out on a shroud 2 surface which is easy to stick the scale while avoiding an end part (impeller outer circumferential part) which attach with a part on which high stress is applied in a pump impeller and a corner part (impeller mouse part), so that it is possible to prevent scale from sticking without being influenced by fatigue strength of the pump impeller, and increasing of power caused in increase of fluid friction loss by sticking of the scale is suppressed so as to save a power consumption remarkably.

Title: Pulse x-ray tube
Inventor: KATO MITSUO
IPC: H01J35/22
Filed: 1989-09-18
Abstract: PURPOSE:To prevent the damage of the insulating material and stabilize the X-ray quantity by generating the glow discharge in a low vacuum area near a cathode, and accelerating the drawn electron in a high vacuum area to make it collide with an anode. CONSTITUTION:A porous plate 2 provided opposite to an anode 3, a cathode 1 provided near the porous plate 2 and formed so as to discharge the electron to be drawn from the porous plate 2 to the anode 3 direction, and a means 4 for supplying the gas to the porous plate 2 are comprised. Consequently, the electron generated by the glow discharge in a hollow cathode 1 is drawn by the electric field to pass through the porous insulating plate 2 and enters to an electron acceleration area 8, but, the electron is accelerated without a collision with the gas molecule because of the high vacuum in the electron acceleration area 8 to eache the anode 3. Since the speed of the electron is reduced quickly in the anode 3, the braking X-ray 9 is irradiated. The electric field intensity to be applied to the surface of the insulating material is thereby reduced to eliminate the damage, and the vacuum degree near the cathode 1 is maintained constantly to stabilize the discharge, and the X-ray quantity is stabilized.
