Title: Ion beam radiating device
Inventor: MORI HARUHISA
IPC: H01J37/317
Filed: 1988-10-14
Abstract: PURPOSE:To reduce the charge-up of the insulating film of a target by insulating a secondary electron generating electrode from a Faraday cup electrode and giving the secondary electron generating electrode a potential specified to the potential of the Faraday cup electrode. CONSTITUTION:A secondary electron generating electrode 7 generating a secondary electron for neutralizing the positive charge accumulated on the insulator face receiving ion irradiation is provided in the inside of a Faraday cup electrode 3 in such a manner as to be insulated from the Faraday cup, and a positive (+) voltage (+5V-+20V) slightly exceeding the voltage corresponding to the initial energy possessed by the secondary electron to the potential of the Faraday cup electrode 3 is applied to said secondary electron generating electrode. Thus, when the insulating film on the processed base 59 face fixed and supported on a target is charged up to positive (+) by the ion beam radiation even if it is few, the secondary electrode floating in the Faraday cup electrode 3 is immediately sucked to the insulating film face to neutralize the positive charge of the insulating film. Hence, the charge-up can be reduced.

Title: Three dimensional image display device
Inventor: SATO TAKESHI
IPC: G06Q50/22
Filed: 1992-09-29
Abstract: PURPOSE:To shorten the processing time, and to execute a display at a high speed, at the time of making three-dimensional image data subjected to stereoscopic vision display, based on a rotational display method. CONSTITUTION:A CPU operates a coordinate obtained by rotating voxel data of the (x)-(z) face at the time when the (y) axis of three-dimensional image data is a rotation axis, by theta degrees (0<=theta<=180 deg.) (step 23). In that case, an initial value determined by the angle theta is set, and by cumulative addition from this initial value, the coordinate of the voxel data of its face is rotated. In each rotational position, a parameter is changed in order of (z), (x) and (y) and projected in the (z) axis (rotation axis) direction, and shading is executed by a (z) buffer algorithm. In that case, by taking notice of a fact that as for the projecting directions of theta degrees, and theta+180 degrees, the lines are the same and the directions are opposite to each other, the projection at the time of theta+180 degrees is also executed together at the time of projection at the time of theta degrees (step 24-34). Subsequently, by changing the rotation angle by 11.25 degrees each, the abovementioned processings are executed (steps 35, 36).

Title: Method for extracting oxide inclusion in steel by electrolytic method
Inventor: ISHIBASHI YOICHI
IPC: G01N27/26
Filed: 1986-11-04
Abstract: PURPOSE:To shorten the time for a refining treatment and to improve the extraction rate of an oxide inclusion by making electrolysis while replenishing an electrolyte from the outside of a system at all times and discharging part of the electrolyte contg. iron ions to the outside of the system. CONSTITUTION:A copper sample plate 1 is used as an anode and two sheets of copper wire nets 2 opposite thereto are used as a cathode. The electrolyte 4 is put into an electrolytic cell 3 and a prescribed amt. per hour of the electrolyte 4 is supplied from a tank 5 for supplying the electrolyte to the bottom of the cell 2 by a fixed delivery pump 6. Electric current is passed to the electrodes from a constant current power supply 7 for electrolysis and the electrolysis is made while the electrolyte is made to flow over an electrolyte discharge port 8. Since the slime of iron hydroxide is not generated at the time of the electrolysis in this case, the need for a magnetic sepn. treatment and treatment by hydrogen reduction which are repeatedly executed for the sepn. of the oxide inclusion and slime like in an electrolytic slime method is eliminated and, therefore, the time for the refining treatment is greatly shortened. Since there are substantially no fluctuations in pH during the electrolysis, the extraction rate of the oxide inclusion is improved.

Abstract: PROBLEM TO BE SOLVED: To easily attach/detach a photoreceptor unit without removing a process element from a supporting member by providing a movable member which incorporates the process element located in an attaching/detaching path and is operated to displace between specific positions. SOLUTION: A discharge lamp (process element) 20 is located to face a photoreceptor 1 in the attaching/detaching path of the photoreceptor unit 11, in a state where the unit 11 is loaded and set in the image forming position of an image forming device main body. Then, the movable member 30 incorporates the discharge lamp 20 and is operated to turn/displace between a operation position A where the lamp 20 fulfills its original function at a position facing the photoreceptor 1 and a retreat position B where the lamp 20 is out of its attaching/detaching path. Therefore, it is unnecessary that the lamp 20 is removed from the supporting member every time the unit 11 is attached/detached and the movable member 30 is merely turned to the retreat position B. Further, the lamp 20 is covered with the movable member 30 so that toner, dust, etc., never sticks to the discharge lamp.

Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To remarkably improve convenience without requesting a special procedure to a regular ticket user by allowing every user to enter only by obtaining a parking ticket at the time of entering. SOLUTION: When a vehicle sensor 111 detects a vehicle at the time of entering without regard to whether it is a general car or a regular packing contracting vehicle, a parking ticket issuing machine 112 automatically issues a parking ticket 114 recording an entering time by means of a magnetic recording part 113 and carries it to a parking ticket fetching port 115 to allow a user to pull out from within the vehicle. When a regular parking contracting vehicle leaves, the ticket 114 issued at the time of entering is inserted to the parking ticket reading port 123 of a charge adjusting device 122. A regular card 124 is inserted to a regular card reading port 133 within a prescribed time and a magnetic reading part 125 reads magnetic data of the card 124.  A card judging part 134 compares it with previously provided data to automatically check a parking low code, a variable period, a card number and the confirming of illegal use. Illegal use is confirmed by comparing the entering time and a last time laving time read from the card 124.
