IPC: C23C22/73
Filed: 1993-03-24
Abstract: PURPOSE:To provide the film treating chamber capable of minimizing the generation of bubbles, dust and solid suspended matter and stirring a bath liquid uniformly at all times to assure coating with uniform film components and film deposition. CONSTITUTION:This film treating chamber 2 is provided with a liquid feeding and stirring conduit 3 having an impeller 4 for feeding and stirring the bath liquid L in the film treating chamber within the chamber continuously thereto.

Title: Magnetic chuck
Inventor: MATSUZAKI YOUICHI
IPC: B23Q3/15
Filed: 1984-04-03
Abstract: PURPOSE:To make high flatness maintainable on a suction surface even in use for years, by forming a groove magnetically dividing a face plate part into magnetic poles of a heterogeneous magnetic pole in an inner surface of the face plate, while making an outer surface of the face plate part into a flat surface through a simple member. CONSTITUTION:When an exciting coil is excited and a part corresponding to an outermost partition wall part 22 of a face plate part 20 is magnetized to an N pole, leakage flux between proximate heterogeneous magnetic pole parts is prevented from occurring at a time when a part corresponding to its inward partition wall part 24 is alternately magnetized to S and N. As a result, when the coil 14 is excited, an outer surface 20b of the face plate part is formed clearly with an annular heterogeneous magnetic pole part so that a work is surely clamped by dint of magnetic force acting on the outer surface 20b. Likewise, with a groove 28, the suction surface 20b is magnetically dividable into heterogeneous magnetic pole parts, and since the suction surface can be constituted of a single magnetic member, highly accurate flatness is securable on the suction surface 20b and, what is more, since there is no partial hardness difference due to a quality difference between materials used, no partial wear is produced, thus flatness for years is maintainable.

Abstract: PURPOSE:To improve head touch and running durability with the ruggedness on the surface of a magnetic layer by the constitution in which island-shaped deposition layers of aluminum oxide are deposited by vapor deposition between a substrate and an underlying chromium layer. CONSTITUTION:Aluminum is deposited by evaporation in an oxygen atmosphere on the substrate 1 polished to a specular surface to form the island-shaped deposition layers 3 of the aluminum oxide; furthermore, the underlying chromium layer 5 and a ferromagnetic layer 7 and, if desired, a surface protective layer 9 are successively deposited and formed thereon to form the outermost surface which is rugged. The articles of the layers 3 are preferably of 30-300Angstrom . The crystal orientational property of the underlying layer 5 and the ferromagnetic layer 7 is undesirably affected if the particle size is larger than said range. The head touch and running durability are improved by such ruggedness of the surface.

Abstract: PURPOSE:To enhance the measuring accuracy and reproducibility of beta-glucan due to a flow injection method using Calcofluor by injecting a sample in a specific ratio with respect to the space vol.amt. of a reaction part. CONSTITUTION:The whole of a system including a Calcofluor reaction soln. 1, a pump 2, a sample injector 3 and a reaction part 4 is kept constant within a temp. range of 0-40 deg.C and the injection amt. of a sample is set to a range of 0.002-0.1ml.

Title: Magnetic recording medium
Inventor: FUJII SHIGEO
IPC: G11B5/706
Filed: 1985-03-29
Abstract: PURPOSE:To obtain the titled medium having excellent resistance to corrosion and weather by composing the alloy magnetic thin film of a Co-base alloy contg. >=1 kind among Al, Si and Cu and nitrogen. CONSTITUTION:The magnetic thin film consists of a Co-base alloy contg. >=1 kind among 2-12atom% Al or Si or 2-8atom% Cu and 0.5-5atom% N. The content of Al or Si is regulated to 2-12atom% and that of Cu to 2-8atom%, because the corrosion resistance is deteriorated at <2atom% contents of the additives. Meanwhile, the saturation magnetization becomes too low at >8atom% Al or Si and the merit of the thinness of the alloy magnetic thin film suitable for high-density recording can not be fully exhibited. Reasons for regulating the N content to 0.2-5atom% are mainly related to the production and because >=0.2atom% N remains in the film. On the other hand, the squareness ratio S among magnetic characteristics is deteriorated at >5atom%.

Title: Packing
Inventor: YANO KICHIYA
IPC: F16J15/30
Filed: 1982-04-19
Abstract: PURPOSE:To effectively prevent the abrasion powder of expansion graphite from sticking to an opponent axis member by depositing lead oxide to the bore surface of a ring packing made of expansion graphite. CONSTITUTION:Since the bore portion of a packing substrate 7 made of expansion graphite in direct contact with an opponent axis member is a lead oxide film 12, abrasion powder of expansion graphite is effectively prevented from sticking to the opponent axis member. Moreover, even when the contact portion with the opponent axis member generates heat, stable and excellent lubricity can be available even at a high temperature without deteriorating the lubricating function or corroding the opponent axis member due to cracking or decomposition as in the case of an organic lubricant such as oil families, etc. or sulfide series lubricant such as MoS2, etc. Therefore, the coefficient of friction is not abruptly increased timewise, and the burning which is apt to occur for the packing made of expansion graphite can be prevented from occurring.

Abstract: PROBLEM TO BE SOLVED: To improve lateral compressive strength of a shoulder of a container to prevent troubles such as the shoulder being recessed under a reduced pressure by peripherally providing a groove rib between a ridge of the shoulder and a plurality of elongated protruding panels formed on a body below the ridge. SOLUTION: A cylindrical container 1 comprising a mouth 1-1, a shoulder 1-2 and a body 1-3 is formed with a neck-like groove rib 12 which is recessed inward immediately below a ridge 11 occurring in a peripheral direction by folding a peripheral wall of the shoulder 1-2. The body 1-3 comprising an upper half body 1-31 and a lower half body 1-32 is connected below the groove rib 12, while six protruding panels 13 having an elongated protruding face 131 are formed on the upper half body 1-31 and a longitudinal protruding line 132 is formed between the adjacent protruding panels 13, 13. Thus lateral compressive strength, that is, resistance against centripetal force functioning toward the center of the container is increased to prevent a shoulder 11 from deforming due to reduced pressure force at the time of filling contents.

Abstract: PURPOSE:To execute the fine adjustment of pressure welding force and to raise reliability of a device by a simple and inexpensive structure by supporting the eccentric sleeve of both sides of a pressure welding roll 2 by a bearing, and pressure welding the fixing roll and pressure welding roll by its rotating operation. CONSTITUTION:A bearing 4 is attached through the eccentric sleeve 3 to both sides of a shaft 2c of the pressure welding roll 2 opposed to the fixing roll 1. In case of setting the rolls 1, 2 to a press welded state, when the press welding roll 2 is half-rotated by a worm gear 5, the whole of the press welding roll 2 is raised by the quantity of two times as much as an eccentric quantity (e) of the eccentric sleeve 3, pressure welded to the fixing roll 1, and since a worm wheel 6 cannot rotate the worm gear 5, the roll 2 is held in that position. When the press welding roll 2 is further half-rotated, the press welded state is released. Accordingly, the pressure welding force can be adjusted finely by the fine adjustment of a driving device, and the reliability of a device is raised by a simple and inexpensive structure.
