Title: Structure of thin film magnetic head
Inventor: AMEMORI KAZUHIKO
IPC: G11B5/39
Filed: 1982-11-19
Abstract: PURPOSE:To improve the magnetic characteristics of a magnetic shielding layer by making it to have contacts between upper and lower magnetic shielding layers of a thin film magnetic head having a magneto-resistance element at both ends in the lengthwise direction of those shielding layers. CONSTITUTION:A magneto-resistance element 4 is held vertically between magnetic shielding layers 6 and 7 via insulated layers 8 and 9. The holes are drilled to the layers 8 and 9 to secure a contact between both layers 6 and 7 at both ends in the lengthwise direction of both layers. Thus a closed loop is formed to obtain a magnetic head. In such a constitution, the layers 6 and 7 are not independent of each other even if the uniaxial anisotropy is applied to the arrangement direction of the element 4. Therefore a magnetic field is never generated within the layers 6 and 7 in the direction orthogonal to both layers. Then the magnetic path circulates within the layers 6 and 7 to minimize the energy of magnetization with high stability. This reduces the permeability of both layers 6 and 7 and does not deteriorate the recording performance of the magnetic head.

Title: Preparation of master mold and core box
Inventor: YOSHIBE TETSUYA
IPC: B22C9/02
Filed: 1986-08-29
Abstract: PURPOSE:To easily obtain a core box and master mold by fashioning a model having the same shape as the shape of the master model and sticking a flexible member to the inside surface of the negative mold to fashion a negative mold, then fashioning the model. CONSTITUTION:The model A having the same shape as the shape of a master mold is formed by working wood. A resin is poured onto the outside of the model A to fashion the negative mold B. The flexible member 2 having the same thickness as the wall thickness of a casting is then stuck to the inside surface of the negative mold B except the core print 1 part of the negative mold B to fashion the negative mold C. The resin is poured into the mold C to fashion the model D and the resin which is a material for the core box is poured onto the model D and is solidified to obtain the core box 3. The operation is thereby facilitated; in addition, the core box and the master mold are formed to exactly the same shape by maintaining the difference in the wall thickness of the casting. The improvement in the dimensional accuracy and the reduction of the production cost are thus permitted.

Title: Boiler
Inventor: FUKUDA HIDEO
IPC: F22B31/00
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To correct a temperature imbalance in a furnace by promoting a combustion of an unburned material delivered from the central portion of the furnace, wherein combustion air is supplied into the furnace from a plurality of burners in a direction which follows the flow of a whirling flame in the furnace by deflecting the combustion air toward the downstream of the flow of the whirling flame. SOLUTION: A flow direction A of combustion air flow blown into a furnace 3 from each burner 1 is deflected toward the downstream of a whirling flame D. Namely, as depicted by the arrow A, each burner 1 supplies the combustion air into the furnace 3 in such a manner that the combustion air is deflected toward the downstream of the whirling flame D so as to follow the flow of the whirling flame D. Due to such a construction, a new combustion air curtain is formed at the side of furnace walls 4, 7 so that the combustion of an unburned material supplied to the furnace walls 4, 7 along with the flow of the whirling flame D is enhanced. Accordingly, no temperature difference exists between the furnace walls 4, 7 and a problem of temperature imbalance in the furnace 3 can be resolved.

Title: Wire dot printing head
Inventor: HARADA MINEO
IPC: B41J2/265
Filed: 1981-12-18
Abstract: PURPOSE:To lengthen life even when the diameter of a wire is decreased by dividing a wire guide into the first and second members guiding at the outside and the inside and forming the first member by a material having a small friction coefficient and the second member by an abrasion-resisting material. CONSTITUTION:A wire guide is divided into an internal plate 20 and an external plate 21, and projections 26 and fitting grooves 25 are fitted, bonded and unified. The wire guide assembled in this manner is incorporated into the printing head, and the guide holes 24 of wire 1 are formed by the grooves 22 of the internal plate 20 and the grooves 23 of the external plate 21. The material having the small friction coefficient is used as the external plate 21 and the material having excellent shock and abrasion-resisting property as the internal plate 20. Consequently, the extension of the guide holes 24 due to shocks can be prevented and breaking can be obviated because the wire is contacted with the surfaces of the grooves 23 when the wire is stopped and retreated and it is contacted with the grooves 22 having shock and abrasion-resisting property only in case of buckling. Accordingly, the wire is not broken and life can be lengthened even when the speed of printing is increased and the diameter of the wire is decreased.

Title: Deciding corrosion resistance of zirconium alloy
Inventor: KUBO TOSHIO
IPC: G01N27/00
Filed: 1989-08-08
Abstract: PURPOSE:To make it possible to decide even if temperature is relatively low and the amount of corrosion is minute by forming an oxide film having a thickness of 10mum or less on the surface of zirconium alloy, thereafter measuring the electric resistance value of the oxide film, and decide the corrosion resistance of the zirconium alloy. CONSTITUTION:An oxide film having a thickness of 10mum or less is formed on the surface of zirconium alloy which is used as a raw material for a nuclear fuel assembly in a water-cooling type atomic reactor. The corrosion resistance of the zirconium alloy is judged by measuring the electric resistance value of the oxide film. There are very minute cracks and air holes in the oxide film which is formed by corrosion in high-temperature, high pressure water or in high-pressure steam. The less the cracks, air holes and the like, the larger the protecting effect to corrosion, and the more excellent the corrosion resistance. Since the electric resistance value of the oxide film strongly depends on the cracks, air holes and the like of the oxide film, the quality of the corrosion resistance can be decided based on the magnitude of the electric resistance.

Title: Trouble cause transmitting circuit
Inventor: KATO KENJI
IPC: G06F11/30
Filed: 1986-08-29
Abstract: PURPOSE:To transmit contents of a trouble cause storage means to a first data processor by connecting the trouble cause storage means and a data bus by the stop signal which is outputted when a central processing unit of a second data processor stops because of trouble. CONSTITUTION:If the second processor B stops the operation by some cause, input/output gates of all circuit elements connected to a data bus are made non-conductive, and a central processing unit 3 outputs a stop signal HALT in this case. This signal passes an OR circuit 5 and makes an input/output gate 41 of a trouble cause register 4 conductive, and a register part 42 where trouble cause data is stored is connected to a data bus C1 of a bus C through an internal bus D. Consequently, trouble cause data are fixed on the data bus C1 as data from the second processor. The first processor A receives the stop signal and interrupts an executing program with a processing routine where the processing accompanied with the stop of the second processor B is executed.
