Title: Driving system of solid-state image pickup device
Inventor: ENDOU YUKIO
IPC: H04N5/335
Filed: 1984-04-13
Abstract: PURPOSE:To widen the dynamic range of a solid-state image pickup device and to prevent picture quality deterioration caused by the whitening of the highlighted part of an object, by giving a knee to the photoelectrically converting characteristic of an inter-line transfer type CCD through its driving method. CONSTITUTION:Signal charge transfer is made in such a way that signal charges QA accumulated in a effective period and signal charges QB accumulated in a blanking period are added to each other by a line shift pulse LS added to a V-CCD and transferred to a horizontal register side. This transfer period becomes the effective period of a vertical blanking pulse. Firstly, only excess electric charges QC are read out to the V-CCD side by the 1st field shift voltage VF1 and a signal charge quantity QA determined by the potential difference between voltages VF1 and VF2 is remained in the picture element. The excess charges QC read out to the V-CCD are swept out to the outside during a vertical blanking period by a high-speed pulse and accumulation of the signal charges QB is again performed during the vertical blanking period. Then the signal charges QA and QB are simultaneously transferred to a vertical register by the 2nd field shift pulse VF2.

Title: Leaf type plasma treatment device
Inventor: YAMAGUCHI YASUHIRO
IPC: C23C14/35
Filed: 1987-03-30
Abstract: PURPOSE:To subject the entire surface of large-area substrate to a plasma treatment at a uniform speed by providing a magnetic field generating means having magnetic lines of force parallel and axisymmetrical with the substrate at the time of subjecting the surface of the substrate to etching or film forming treatment by the plasma treatment. CONSTITUTION:The substrate 4 to be treated is imposed on an electrode plate 5 in a vacuum chamber 1 and many permanent magnets 12 are installed around the same coaxially with the substrate. The surface of the permanent magnets near the substrate 4 are made as an N pole and the surfaces opposite thereform are made as an S pole. An earth electrode plate 8 is mounted in parallel to the position opposite to the electrode plate 5 and after the inside of the chamber 1 is evacuated by a vacuum pump 3, a plasma reactive gas is supplied into the chamber from a pipe 9 and is released from the holes provided to the electrode plate 8. The plasma is simultaneously generated between the electrode plates 5 and 8 by a high-frequency power supply 6. The plasma is simultaneously generated between the electrode plates 5 and 8 by a high-frequency power supply 6. The plasma treatment speeds in the peripheral part and central part of even the large-area substrate 4 are thereby equalled by the magnetic fields formed by the permanent magnets 12 in this case. The entire surface of the substrate 4 is thus subjected to the uniform plasma treatment at the high speed.

Abstract: PURPOSE:To reduce a decentering aberration generated at the time of camera shake compensation by using an aspherical surface lens which has nearly no refracting power in a fixed lens arranged on the object side of a lens group that moves at the time of camera shape prevention. CONSTITUTION:A vibration-proof optical system 8 is mounted in front of a photography system 11 and has two lens groups, i.e., a 1st group (focal length f1) having negative refracting power and a 2nd rotatable group 2 (focal length f2) having positive refracting power in order from the object side. When the photography system 11 slants, the 1st group 1 slants at the same angle together with the photography system 11. The 2nd group 2, on the other hand, is spatially fixed by a counterweight 4. At this time, the 2nd group 2 is given the same angle of light beam deviation as the tilt angle of the photography system 11 to correct a camera shake. Then the 1st group 1 is provided with the aspherical surface 7 which has nearly no refracting power to reduce the decentering aberration generated at the time of the rotation of the 2nd group 2.

Abstract: PROBLEM TO BE SOLVED: To connect a data transferring path without receiving restriction by resources by using a data list coordinating a name for identifying a connection opposite side and information unitarily deciding the connection opposite side so as to enable optionally to select a connection opposite side. SOLUTION: A data communication control program 11 carries out the connection processing of the data transferring path 14 in response to the connection request of the path 14 from a data processing program 18 or connection opposite sides 15 to 17.

Filed: 1990-03-22
Abstract: PURPOSE:To prevent the generation of misregistration by making sealing double from the outermost periphery where a pair of electrode substrates are superposed and initially curing the outer seal, thereby temporarily adhering a pair of electrodes. CONSTITUTION:The seal 2-1 is formed of a photosetting adhesive on the lower side of the electrode substrate 1-1 by a screen printing method. The seal 2-2 is formed of a thermosetting adhesive on the upper side of the electrode substrate 1-2 by the screen printing method. After the electrode substrates 1-1, 1-2 are superposed on each other, the entire part is irradiated with UV rays 4 to cure only the seal 2-1 of the photosetting adhesive. The substrates are thereafter heated while the substrates are pressurized from the outside surface to cure the seal 2-2 which is the thermosetting adhesive. The generation of the registration is prevented in this way even by the pressurization at the time of curing of the seal in the inner side.

Title: Controlling method of current for welding accompanying short circuit transfer
Inventor: OGASAWARA TAKAAKI
IPC: B23K9/073
Filed: 1983-04-28
Abstract: PURPOSE:To decrease generation of spatter and to prevent failure in regeneration of an arc by decreasing the short-circuit current of a consumable electrode wire upon detection of the necking of a droplet and returning the short-circuit current to the prescribed short-circuit current or above when no arc is generated. CONSTITUTION:A comparator 114 compares the set value set by a setter 115 and the output from a voltage detector 110 and judges that a consumable electrode wire is necked when the voltage excceeds the set value. The comparator 114 applies a control signal to a welding power source 101 and changes over a switch to a setter 121 on a low current side to decrease the current on the consumable electrode wire 103. A timer 123 starts clocking from the point of the timer when the necking of the droplet is detected by the signal of the comparator 114 and changes over a switch 120 to a setter 124 to supply the original short-circuit current or slightly larger current if no arc is regenerated within a specified time. The end of the consumable electrode wire is melted and the arc is again generated by the short-circuit current.

Abstract: PURPOSE: To improve the responsiveness by sharply shortening the time until drainage being started after the water level in suction well reaching the water level to start pumping, and to enable preceding standby operation. CONSTITUTION: White the water level of a suction well 1 goes up from the water level LWL to stop operation to the water level HWL to start pumping, the water level within a suction pipe 4 is pulled up by the height H2 over which water flows into an impeller 3 from the water level HWL to start pumping, and is kept there, by the operation of a vacuum pump 2 and the aperture control of a throttle valve 8A interposed in the first branch intake pipe 8, and then a discharge valve 6 is opened, and aerial operation is performed.  When the water level goes to HWL, the water level within the suction pipe 4 is pulled up to the level SL where water flows into the impeller 3, and besides the top aperture 8a of the first branch intake pipe 8 is sunk under the water surface, and the water level within the pump is pulled up roughly instantaneously to full water level HHWL by making the high negative pressure of the vacuum pump 2 act upon it, thus the operation is changed over to pumping operation, and when the water level drops right under the water level LWL to step operation, the tip aperture 9a of the first branch intake pipe 9 is opened to change the operation over to aerial operation.
