IPC: B65H7/06
Filed: 1986-09-17
Abstract: PURPOSE:To make a duplex original so as to be copied simply and accurately, by installing an original tray, a turnover part and a discharge part of an original, and a controlling device for loading the original on a platen in page order at the discharge part at the time of copying suspension, altogether. CONSTITUTION:An automatic duplex original feeder is provided with an original tray 1 loading originals in paper order, a turnover part 4 turning over both sides of each original to be fed onto an original platen 6, a discharge tray 5 loading the original on the original platen 6 and discharging and housing it, and a controlling device controlling the original on the original platen 6 so as to be loaded in page order by the discharge tray at the time of copying suspension in a copying machine. During copying, when copying paper is jammed, whether a surface of the original on the original platen 6 is a larger side or a smaller one in page is discriminated on the basis of the contents of an original memory part. In case of the smaller original surface in page, that is, discharge motion is carried out. Reversely, in case of the larger original surface in page, once turnover motion takes place and the original surface is turned over, and then the discharge motion is carried out.

Title: Production of rare earth metal or alloy of rare earth metal
Inventor: TAMAMURA HIDEO
IPC: C25C3/34
Filed: 1987-09-03
Abstract: PURPOSE:To considerably increase the yield of a rare earth metal or an alloy of a rare earth metal without changing the structure of the conventional electrolytic cell when the metal or alloy is produced by a molten salt electrolysis method, by providing a plate shape to electrodes, keeping the interval between the electrodes unchanged and maintaining constant current density at all times. CONSTITUTION:For example, an Nd-Fe alloy is produced with molten LiF-NdF3 or LiF-NdF3-Nd2O3 as molten salt and plate-shaped consumable electrodes of graphite and iron as the anode 3 and the cathode 4, respectively. Even when the anode 3 is consumed, the area is practically unchanged and constant current density can be maintained at all the times. Since the interval between the cathode 4 and the anode 3 can be kept unchanged over the principal reaction surfaces set opposite to each other, a uniform electrolytic reaction can be maintained over the entire reaction surfaces. By this invention, the yield of the alloy can be increased by about 10 times without changing the structure of the conventional electrolytic cell.

Inventor: EDA RYUJI
IPC: G11B7/08
Filed: 1994-08-23
Abstract: PURPOSE: To improve an MTF and to enhance bit read precision by arranging a semiconductor laser element while inclining it by a specified angle around an optical axis and forming an elliptic spot having its major axis inclined by the angle concerned to a track on a recording surface of an optical disk. CONSTITUTION: A return light beam passing through a beam splitter 13 is converged by a condenser lens 17, and respective light beams separated by a grating 12 are made incident on corresponding light receiving surfaces on a photodetector 18 respectively. Thus, a read signal, a focus error signal and a tracking error signal, etc., of the optical disk D are generated based on detection signals from respective light receiving surfaces of the detector 18. In such a case, a laser light beam irradiating the recording surface of the disk D becomes the elliptic spot having the major axis inclined by 45 degree to the track 190 on the recording surface of the optical disk D by that the semiconductor laser element 11 is arranged inclining by e.g. 45 degree around the optical axis. Thus, resolution is enhanced.

Filed: 1989-08-28
Abstract: PURPOSE:To automatically relieve a transaction at the time of the occurrence of trouble in a data base and to restore and execute it by providing a transaction managing means, a transaction saving means, and a transaction restoring means. CONSTITUTION:A transaction managing means 11 uses a transaction management table to manage relations between transactions and data bases used by them and trouble information of each data base. If trouble occurs in a data base 3, a transaction saving means 12 refers to the transaction management table updated by the transaction managing means 11 to save a transaction to a relief file 4; and when trouble of the data base 3 used by the saved transaction is recovered, a transaction restoring means 13 restores the transaction from the relief file 4 to execute it. Thus, the transaction is automatically relieved and is restored and executed at the time of the occurrence of trouble in the data base 3.

The film 15 which is capable of preventing the ions from being implanted is patterned so as to be left only in a region which is to be used as the channel part of a transistor. Then, oxygen ions are implanted, and a buried SiO2 oxide layer 12, a damaged Si layer 13 and a single-crystal Si layer 14 are formed. Then, the film 15 is removed, the crystallinity of the damaged Si layer 13 is restored, a single-crystal Si layer 14' is formed, and an isolated single-crystal Si layer 16 is formed on the buried SiO2 layer 12.  At this time, the single-crystal Si layer is formed in such a way that the thickness of the Si layer is thin in a part which is to be used as the channel region of a MOS semiconductor element and that the Si layer is thick in a part which is to be used as its source-drain region.

IPC: F24F7/00
Filed: 1990-08-22
Abstract: PURPOSE:To keep the cooling efficiency of an air-conditioner in a good condition by naturally exhausting hot-air in an interior space, by a method wherein a cover lid is placed on an opening on the side of the outside air of a cylindrical hollow body and a cylindrical attracting- plate is arranged at the position in the vicinity of the opening on the side of the outside air there of. CONSTITUTION:An attracting plate 32 is formed of a cylindrical body 32a which is concentrically placed at the periphery of a cylindrical hollow body 16 and a radial clearance is formed and is supported by three bars 34 projected at radially symmetrical positions on the cylindrical hollow body 16. Under a condition under which a cover lid 20 is lifted at an opening 14 on the side of the outside air and the cylindrical hollow body 16 is opened, the air flowing in any direction on the upper part of the attracting plate 32 enters a clearance between the cover lid 20 and the opening 14 of the cylindrical hollow body 16, and the air swirls by this attracting plate 32 and passes again outwards. By a negative pressure caused by a vortex at that time, hot-air staying in an interior is attracted and exhausted through an opening 12 on the side of the interior of the cylindrical hollow body 16. In this way, even if the air flows in any direction, it is possible to exhaust the hot-air, and since the cover lid 20 is in plane, round shape and has an outer diameter of which the size can close the opening 14, raindrops can be prevented from entering through the attracting plate 32.

In this case, the outer circumferential surface of the cam 66 pushes a pin 74. As a result, a lever 73 is turned counterclockwise around the shaft 72. Thus a pin 84 provided to a slider 83 is pushed by an eccentric pin 75 of the lever 73, and a slider 83 containing a magnetic head 85 moves along guide shafts 81 and 82. Hereafter the head 85 is moved in response to the repeating times of ON/OFF actions for energization to the solenoid 52.
