Title: Hot dip metal coating method for hot rolled steel sheet stuck with oxide scale
Inventor: AOKI TOMOHISA
IPC: C23C2/06
Filed: 1992-11-11
Abstract: PURPOSE:To make hot dip metal coating of a steel sheet without descaling the steel sheet by directly reducing the hot rolled steel sheet in a reducing gaseous atmosphere at a specific temp. while hot rolling scale is held stuck thereto as a pretreatment. CONSTITUTION:The hot rolled steel sheet stuck with the oxide scale is reduced at 300 to 750 deg.C in the reducing gaseous atmosphere and is then subjected to the hot dip metal coating. Gases consisting of 2 to 100% hydrogen concn. and the balance gaseous nitrogen are used as the reducing gases. The use of the gaseous mixture composed of the hydrogen and the nitrogen is more inexpensive than the gaseous hydrogen alone. The reduction of the scale is insufficient and the good plating is not obtainable in spite of increasing of the concn. of the gaseous hydrogen if the temp. at the time of reduction is below 300 deg.C. On the other hand, the plating is good but there is a possibility of a change in the mechanical properties of the hot rolled steel sheet if the temp. exceeds 750 deg.C. The time for the reduction is shortened if the steel sheet is preheated before the reduction.

Title: Ink jet recording head
Inventor: KUBOTA HIDEMI
IPC: B41J2/175
Filed: 1988-12-26
Abstract: PURPOSE:To stabilize the ink jetting performance by providing a sound reflecting board bent into a recessed form close to an ink supply port. CONSTITUTION:Owing to the reciprocating move of an ink jet recording head 25, a flexible ink supply tube 1 reciprocates simultaneous as a recording head 25. Consequently, the flow rate of ink supplied from the ink supply port 16 varies, which is emitted as an acoustic wave to a subtank 10. Since the subtank has the sound reflecting board 33, an acoustic wave emitted at each point of the ink supply port 16 is image-formed as an acoustic image 4 in a prescribed area on an ink liquid surface 13. Then, this acoustic image 4 causes ink liquid 17 to generate a surface wave, and the acoustic energy of the acoustic image 4 spreads on the ink liquid surface 13 and is absorbed as heat energy by the liquid around the surface. Thus, the influence of fluctuation in the amount of ink supplied from the ink supply port is minimized to obtain a stable ink jetting performance.

IPC: F24H9/00
Filed: 1996-11-21
Abstract: PROBLEM TO BE SOLVED: To embody a catalytic combustor capable of inhibiting the velocity of combustion gas passing through a vessel in the whole area of a heat exchanger and representing an excellent heat exchange efficiency. SOLUTION: A fuel gas supply pipe 2 is provided in the central part of a cylinder-shaped vessel where a large number of small holes 21 serving as a gas supply hole is provided on the pipe wall, thereby diffusing the fuel gas supplied from the gas supply pipe 2 by way of the small holes toward the outer peripheral part outward in the radial direction from the central part of the vessel 1. A plurality of tubes 31 are laid out in the shape of layers on the outer periphery of the fuel gas supply pipe 2 where a heated fluid is flowing in the tubes 31 surrounding the gas supply pipe 2. Fins 32, which bears oxidative catalyst are joined with the outer surfaces of the tubes 31.  Since the fuel gas supply pipe 2 is laid out in the central part, the cross section of gas passage is increased with the radius of the pipe so that the heat generated by an increase in the velocity may be transmitted to the passing gas. This construction makes it possible to prevent the heat from being discharged. It is, therefore, possible to use the heat generated by the oxidative reaction of the catalyst for the heating of the heated fluid with higher efficiency.

Abstract: PURPOSE: To suppress the generation of Barkhausen noise and to obtain a high- sensitivity head by constituting a multilayered film element so as to have an axis of difficult magnetization in a direction orthogonal to the sliding direction of a magnetic recording medium. CONSTITUTION: An insulating layer 12, a lower magnetic pole 2 and an insulating layer 13 are successively formed on a nonmagnetic substrate 11 and the multiayered film element 7 and an insulating layer 18 are formed on the layer 13. The element 7 is so formed that its longitudinal direction intersects orthogonally the sliding surface (a) of the magnetic recording medium. The element is so formed as to have the axis of difficult magnetization in the direction orthogonal to the sliding surface (a) of the magnetic recording medium by managing anisotropy in the forming stage. The vertical type thin-film magnetic head is composed by holding the element 7 with the magnetic pole 2 and the upper magnetic pole 3.  As the result, the direction of the axis of difficult magnetization coincides with the propagation direction of magnetic fluxes and, therefore, the magnetic walls are not generated and the generation of the Barkhausen noise is averted. In addition, stably high output is obtd.

Title: Magnetic head and magnetic recording method
Inventor: TERASONO KOJI
IPC: G11B5/23
Filed: 1988-12-26
Abstract: PURPOSE:To prevent the occurrence of an artificial gap to improve recording and reproducing characteristics by forming a high-saturation magnetic flux density alloy thin film having a saturation magnetic flux density higher than that of a core on one end face of the gap part of the core on a foundation film consisting of a soft magnetic metal. CONSTITUTION:A high-saturation magnetic flux density alloy thin film 2 is provided on one end face of the gap part of a core part 1, and a low-saturation magnetic flux density alloy thin film 4 is provided on the other end face. The high-saturation magnetic flux density alloy thin film 2 is formed on a foundation film 5 consisting of a soft magnetic metal. That is, the low-saturation magnetic flux density alloy thin film 4 is magnetically saturated to function as a part of the gap at the time of recording and a strong magnetic flux from the high-saturation magnetic flux density alloy thin film 2 is impressed then. At the time of reproducing, the low-saturation magnetic flux density alloy thin film 4 functions as a part of the core and reproducing with a narrow gap is performed. Since the foundation film 5 has a similar crystal structure, an artificial gap is not generated on the boundary between the high-saturation magnetic flux density alloy thin film 2 and the core 1. Thus, recording and reproducing characteristics are improved.
