Title: Optical cross-talk attenuating system for optical disk drive
Inventor: JIEIMUZU SHII MAKUDONARUDO
IPC: G11B7/09
Filed: 1991-01-17
Abstract: PURPOSE: To provide a method attenuating a component induced by optical cross talk in a focus error signal of an optical disk drive having tracking and focusing servo systems. CONSTITUTION: An optical disk is scanned at a track crossing frequency larger than the band width of the focusing servo system in a periphery of its tracking axis during corrective operation performed when a new disk is inserted. The focus error signal generated while the disk is scanned is filtered in a pass band containing the track crossing frequency. A cross talk value equal to the value of the filtered focus error signal is decided as a function of an answering value of a tracking error signal to be stored in a memory. Corrective operation is performed while the data are read/written on the disk. During the corrective operation, the cross talk value is read out from the memory as the function of the corresponding value to the tracking error signal to be added to the focus error signal.

Title: Electron beam working machine
Inventor: NAKASAKI TAKAMITSU
IPC: B23K15/00
Filed: 1981-01-16
Abstract: PURPOSE:To prevent deviation of an electron beam due to residual magnetism of a member to be welded and always direct the beam to correct direction in welding two members different in sectional form by an electron beam by detecting the electron beam with an electron beam detecting sensor, and thereby controlling the position of the electron beam. CONSTITUTION:An electron beam 8 is generated by an electron gun 25, and the joint plane 12 of two members 10, 11 having different sectional forms is irradiated and melted, and welded with a welding metal 9. In this case, if the object 11 to be welded has projection on the side of incidence of the electron beam 8, irregular magnetic field is generated in the path of the beam by residual magnetism, and the electron beam is deflected and sometimes is out of place from the joint plane 12 partially. At this time, the electron beam 8 is detected by a beam detecting sensor 13, and the deflecting coil 5 of the electron gun 25 is controlled by signals from an electron beam position controlling device 14 so that the detected quantity becomes a fixed value. Thus, the electron beam 8 is always made incident correctly to the joint plane 12 and excellent welding is effected.

Title: Paper transport mechanism
Inventor: MATSUOKA EIJI
IPC: B65H20/20
Filed: 1990-01-11
Abstract: PURPOSE:To feed a paper smoothly by setting the locking force of a locking means for positioning a tractor to a supporting member to be a value enabling a paper feed mechanism itself to move in the same direction as an axial direction of the supporting member when a sprocket pin is pulled in the axial direction of the supporting member by a sprocket hole. CONSTITUTION:The locking force of a locking means 14 for positioning a trac tor to a shaft 10 is set to be a value allowing the tractor to move in the same direction as an axial direction of the supporting member 10 when a sprocket pin 4a is pulled by a sprocket hole 3 to the axial direction. Therefore, an urging means 16 such as a tension spring 15 is provided in the locking means 14 to urge a lock lever 12 to the locking direction. In this constitution, when a continu ous form paper 1 gets dry and shrinks to reduce the pitch of the holes 3 in a widthwise direction, the pin 4a is pulled by the hole 3 thereby to move the pin belt tranctor on the shaft 10. Therefore, the pitches of the pins 4a of a pin belt 4 and of the sprocket holes 3 of the continuous form paper 1 are auto matically agreed, thus preventing the generation of jammings or the like.

Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To realize the weight balance by advancing a first projection into a center part of a forming stock to remove the material outside, and keeping a second projection advanced in a formed bottomed hole at a prescribed distance from an opposite second die during the press. SOLUTION: A forming stock 5 is inserted in a first lower die 1a. An upper die 2 is lowered at a constant speed to hold the forming stock. A first projection 4a of the lower die 1a is moved upward to remove a part of the forming stock 5 from the center to the side. The ratio of the volume to be re-distributed to the terminal position and the outside of the projection 4a is related to the weight of the forming stock 5 and calculated by the control system to compensate the deviation of the weight of the forming stock 5. A press die is opened, a wheel is loaded on a second lower die 1b, and the upper die 2 is lowered. A second projection 4b is advanced into a bottomed hole and lowered into the upper die 2 at the same speed to achieve the press. The weight can be balanced with the small pressure.

Abstract: PURPOSE:To obtain the zirconia sol uniform in particle diameter and excellent in dispersibility and stability in preservation at the time of hydrolyzing a zirconium alkoxide to form a zirconia sol by supplying the water required in hydrolysis directly into a solvent through a porous glass. CONSTITUTION:A zirconium alkoxide is hydrolyzed in an aliphatic alcohol solvent to form a zirconia sol. In this case, the water required in hydrolysis is directly supplied into the solvent through a porous glass. A commercially available porous glass is used as the porous glass, and the pore diameter is preferably controlled to 5000-30,000Angstrom . Since the pore diameter of the porous glass is correlated with the diameter of the sol particle, the pore glass can be selected in conformity to the particle diameter of the desired sol. The thickness of the glass is ordinarily adjusted to about 0.1-5mm. The water is vaporized and smoothly passes through the glass. In this case, air and an inert gas such as nitrogen are preferably used as the carrier gas.

Abstract: PURPOSE:To exclude the adverse affection of atmosphere outside of an ice making chamber and produce transparent ice stably, by providing the ice making chamber with an openable door body at the front opening thereof. CONSTITUTION:Under a process wherein a heater 11 is conducted and transparent ice is produced, cold air, which flows in a refrigerating chamber by convection, or warm-air, which invades into the same chamber by the opening and closing of a door, are shielded by a door body 26, provided so as to cover the front openings of a first ice making chamber 22 and a ventilating passage 23. Accordingly the cold air and the hot-air will never invade into the first ice making chamber 22 and the production of transparent ice is advanced under a stabilized condition, therefore, the deterioration of transparency due to the fluctuation of ice making time or the variety of transparency of whole of the ice in the first ice making pan 15 will never be generated. On the other hand, the front surface of the ventilating passage 23 is covered by a door body 26, therefore, warm-air, which invades by the opening and closing of the door for the refrigerating chamber, will never flow. into the ventilating passage 23 directly and it makes hard to increase the temperature of a cooling plate 13, therefore, ice making time will never be elongated and the ice making time may be stabilized much more. Further, the amount of leakage of heat from the first ice making chamber 22 to the outside of the chamber is reduced and the heating efficiency of the heating plate 12, heated by the heater 11, may be increased whereby an electric power consumption may be reduced.
