摘要： PROBLEM TO BE SOLVED: To increase electron emission efficiency by forming an insulating material layer provided between an electron feed layer made of a metal or a semiconductor and a metal thin film electrode emitting electrons into a vacuum space via the electric field applied between it and the electron feed layer with a dielectric layer formed by vacuum deposition and having a specific film thickness. SOLUTION: An insulating material layer 13 formed on an electron feed layer 12 made of a metal or a semiconductor such as Si on a substrate 10 having an ohmic electrode 11 is made of a dielectric substance such as SiO2 and having the film thickness of 50 nm or above. The dielectric layer 13 is formed into the polycrystalline phase anchor amorphous phase by vacuum deposition at the film forming rate of 0.5-100 nm/min, it is made of grain lumps of about 20 nm, and electrons are tunneled through the thick film. The emission current by the electrons emitted from the thin film layer 15 into a vacuum space by the voltage applied between the metal thin film layer 15 on the insulating material layer 13 and an ohmic electrode 11 is saturated from the film thickness of 50 nm of the insulating material layer 13 through which electrons pass. Through holes are hardly generated because of the thick film.

摘要： PURPOSE:To prevent the infiltration of moisture from a substrate surface and adhesive layer and to prevent the peeling and corrosion a recording layer by forming a groove region in the entire region wider than the recording region formed on the recording layer. CONSTITUTION:The grooves 6 for increasing the recording density in the radial direction of the recording surface is provided on the surface of a transfer layer 2 in the entire range wider than the recording region 8 formed on the recording layer 3, by which the groove region 7 is formed. Since the contact surface of the transfer layer 2 and the recording layer 3 is adhered at the rugged surfaces formed by the grooves 6, the infiltration of the moisture from the substrate surface and the adhesive layer 4 is prevented. Then, the peeling of the recording layer 3 and the corrosion of the recording layer 3 by the oxidation of the metallic material incorporated into the recording layer 3 are prevented. There is no possibility that the recording and reproducing functions of the recording region 8 are failed by corrosion.

摘要： PURPOSE:To improve sensitivity by changing the desired metal component content of the thin film of an amorphous alloy constituting the magneto-optical disk to a desired extent to specify the composition gradient. CONSTITUTION:A magneto-optical layer consisting of the film of an amorphous alloy of a rare-earth metal and a transition metal having the uniaxial magnetic anisotropy perpendicular to the layer surface is provided on a transparent circular substrate to obtain the magneto-optical disk. In this case, the transition metal content of the amorphous alloy film is radially reduced from the center of the substrate to obtain a composition gradient. As a result, the effect of heating is uniformized, the initial characteristics such as C/N and sensitivity are made uniform on the inner and outer peripheries of the disk, and a magneto- optical disk for a constant angular velocity (CAV) with the sensitivity enhanced is obtained.

摘要： PURPOSE:To obtain tracking information even by a DRAW or an E-DRAW disc where no pre-group is formed in advance by applying tracking control based on a light via a disc recording face by a spot light for detecting tracking information. CONSTITUTION:Only the reflected light by the tracking information detection spot light E reflected on the recorded track is made incident in a photodetector 11 by arranging an analyzer 9 perpendicularly to an analyzer 8 with respect to an optical axis. The photodetector 11 is formed as a 2-split or a 4-split photodetector so as to obtain a tracking signal in response to the deviation of the tracking information detection spot light E from the center of the recorded track. Then the spot light E is controlled to have a deviation zeroed to the recorded track based on the said tracking signal so as to make a track pitch (p) of the recorded track by the information recording spot light O constant.

摘要： PURPOSE:To obtain particles having uniform particle size at low cost in the manufacture of ultrafine metallic powder by blowing gas against an arc column, an anodic flame and a molten metallic material from the circumference to control the average particle size and the particle size distribution of the ultrafine metallic particles. CONSTITUTION:An arc column 10 is generated by impressing an electric current between a metallic material 11 on a copper hearth 4 and a cathodic electrode 3 in order to melt the metallic material 11. Then an anodic flame 12 of the ultrafine metallic powder is formed and sent upward in a vessel 1 by circulating gas. At this time, the circulating gas is blown continually against the metallic material 11, the arc column 10 and the anodic flame 12 from injection nozzles 13 through an introducing tube part 13A. The shape of the arc column 10 is self- contracted with different pinch effects and throttled upon the molten surface of the metallic material 11, and the ultrafine metallic powder having uniform particle size is formed. The ultrafine metallic powder is recovered by a filter 6 in a recovering part 5, and the circulating gas is circulated through a pump 18.
