Title: Disk clamping device
Inventor: AIKO HIDEKI
IPC: G11B17/028
Filed: 1987-11-19
Abstract: PURPOSE:To give no deformation to a disk in case of separating the disk from a disk hub by incorporating the elctromagnet of >=one piece and at equal intervals in a flange and incorporating a circular ring of superconducting material in the disk hub at the position opposed to this electromagnet. CONSTITUTION:The device incorporates >=one piece of a permanent magnet 2 at equal intervals at the position of a radius (r1) from a disk motor 1 and motor shaft core, having the flange 3 incorporating >=one piece of electromagnet 2 at equal intervals at the position of a radius (r2) (not equal to r1). It is moreover integral with a disk 7, incorporating the circular annular ferromagnetic materials 4, 5 of radius (r1) for the disk center and also incorporating the circular annular superconducting materials 9, 10 of radius (r2), and equipped with the disk hub 6 adhered by allowing the disk center coincide with the motor shaft core. In case of separating the optical disk 7 a current is passed in the same direction to an electromagnet 8, then the superconducting material 9 is made to exist in the magnetic field generated by the electromagnet 8 and the disk hub 6 is separated from a flange 3 by Meissner effect. No deformation can thus be given to the disk in case of the separation.

Title: Calibration of surface inspection apparatus
Inventor: OKUNO MAKOTO
IPC: G01N21/88
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To enable simple and rapid calibration by dispensing with a line stopping and calibrating reference plate by calibrating an optical system on the basis of the magnitude of the intensity of reflected light at the aperture provided to an object to be inspected. SOLUTION: The leading and rear ends of respective lots (coils 1, 2) are welded on a line inlet side to be subjected to rolling treatment, pickling treatment or the like while fed at a high speed and, thereafter, the region in the vicinity of the welded part of steel panels is cut off on a line outlet side and the steel panels are taken up in a coil form at every lots. The abnormality generated in this line is detected to perform surface inspection on the line outlet side by an optical system. Therefore, an aperture K is provided to a region exerting no effect on product yield and a dimension. DL in a longitudinal direction is not made too large to prevent the deterioration of product yield. A dimension DC in a lateral direction may be set so as to stably feed the coils.  When the optical system is not sufficiently adjusted at a time of inspection, the difference between the intensities of reflected lights from the aperture K and a part having no aperture becomes small as compared with a sufficiently adjusted case. Therefore, if the intensity of the reflected light at the aperture K is a calibrating threshold value or less, calibration is unnecessary and, if more, calibration is judged to be necessary to adjust the optical system.

Title: Piston engine
Inventor: MARUKU YOHANESU MARIA UORUFUSU
IPC: F16J10/04
Filed: 1989-11-13
Abstract: PURPOSE: To keep a piston in a determined central position by forming wedged shaped gaps in each sides of reversing face crossing motion direction of the piston that reciprocates in a gas filled cylinder and divides the interior of the cylinder into a first and a second chambers. CONSTITUTION: In a piston engine, a piston 5 is reciprocated in a cylinder 3 by a translation mode 19, a first chamber 39 (compression space) connected to an opening 35 and a second chamber 41 are divided by the piston, and a gap 43 is formed between outer wall of the piston 5 and inner wall of the cylinder 3. The two chambers are interconnected via ducts 37, 45, 47, 49, 51, 53, and helium gas is filled in the two chambers 39, 41. The gap 43 is in annular wedge shape and has the size at least equal to a half of the piston stroke. While volumes of the two chambers 39, 41 are equal, they are symmetrical about the line 57, so no displacement of the piston 5 from the central line 1 caused by the flow quantity flowing through the gap occurs. Therefore, the piston can be kept at the determined central position.

IPC: H04N9/04
Filed: 1992-10-08
Abstract: PURPOSE:To reduce a color deviation even at the time of an animation photographing by operating an entire picture element scanning at the time of a still picture photographing, operating a thinned-out picture element scanning at the time of the animation photographing, and shortening the reading time of a solid-state image pickup element. CONSTITUTION:When an object is the still picture, a selection switch 7 is selected so that a horizontal shift register 3 for the entire picture element scanning can be operated, and a horizontal shift register 4 for the thinned-out picture scanning can not be operated, according to a control signal inputted from an input terminal 8. Thus, horizontal selection switches S21 and S22 for the thinned- out picture scanning are turned into an open state. When the object is moved, the selection switch 7 is switched so that the horizontal shift register 4 for the thinned-out picture element scanning can be operated, and the horizontal shift register 3 can be not operated. Then, the horizontal shift register 4 is operated so that picture element rows can be thinning-out scanned every other row, and a picture signal read in a short time can be outputted from an output terminal 6. Thus, the picture signal can be fetched at a high speed, the color deviation can be reduced, and the unnaturality of the picture can be canceled.

Filed: 1988-11-21
Abstract: PURPOSE:To provide a good cycle characteristic by producing a baked substance through heating of a mixture of MnO2 and Li2CO3 at a certain temp., and by using this baked substance as a positive electrode active substance. CONSTITUTION:A baked substance obtained by heating a mixture of MnO2 and Li2CO3 at 600-900 deg.C is used as the positive electrode active substance of a non-aqueous electrolyte secondary battery. This heating shall preferably be carried out at two stages; first at a temp. between 600-700 deg.C and then at 800-900 deg.C. When this heating is made, Li in Li2CO3 is substituted with the hydrogen contained in MnCO3 in the form of H2O or OH, and thereby dehydration of MnO will be made approx. perfectly. Therein little bireactions will take place at for ex. charge/discharge, such as water going out of pos. electrode active substance into the electrolyte so as to turn the Li inactive. This accomplishes a non-aqueous electrolyte secondary battery with less drop of capacity at charge/discharge cycles and with a longer cyclic lifetime.
