Abstract: Provided is a measuring device 1 for measuring the size of an object comprising a body 2, and a spindle 3 which is screwed into the body 2 and axially advances and retracts by screwing with respect to the body 2, the measurement being based on the axial displacement of the spindle 3 effected by the revolution of the spindle, wherein the spindle is screwed into the body 2 via a multiple-start thread 31. Therefore, it is possible to displace the spindle 3 at a high speed, which improves the operability of the measuring device.

Abstract: A capacitor of the present invention includes a hollow capacitor element prepared by winding a pair of flat electrodes with a separator sandwiched in-between in such a way that both ends of each respective electrode protrude in a direction opposite to each other, an electrode connecting member connected to each respective end surface of the electrode of the above, by metal plasma-spraying, welding, soldering and adhesion using a conductive adhesive, and a terminal for external connection is connected to the electrode connecting member. A cylindrical metal case contains the capacitor element together with a driving electrolyte and a sealing plate closing the opening of the metal case. A reduction in resistance of electrodes is made possible and, in addition, the capacitor can be made smaller in size and the number of the components can be decreased.

Abstract: The present invention relates to an artificial latticed multi-layer film deposition apparatus for depositing on a substrate a gigantic magneto-resistive effect film (GMR film) having an artificial lattice structure formed of magnetic metal films and non-magnetic metal films alternately laminated one over the other and its object is to provide the artificial latticed multi-layer film deposition apparatus to enable easy and secure deposition of an artificial latticed multi-layer film having GMR characteristics.

Abstract: For transfer of memory contents between an extended buffer memory and one of a first and a second main memory and of a peripheral storage device connected to an input-output processor, a transfer controlling arrangement can simultaneously receive transfer requests produced by a central processor, an arithmetic processor, and the input-output processor and can control the transfer requests. The transfer controlling arrangement comprises an extended buffer memory transfer controller connected to the central and the input-output processors through a first transfer controller, to the arithmetic processor through a second transfer controller, and to the extended buffer memory.

Abstract: The invention relates to an electric double layer capacitor in which a metallic piece for a case at the side of an anode is formed with an aluminum layer. The aluminum layer has an electrochemically stable anodized film according to an applied voltage and has so low a resistance as not to present any practical problem. This property is effectively utilized to impart a breakdown voltage not less than 3 V to the capacitor.

Abstract: Improvements of a process for producing a non-directional electrical steel sheet free from ridging, which comprises making a molten steel into slabs by continuous casting, hot rolling the slab, cold rolling the hot rolled product into a final thickness by a single step, and subjecting the cold rolled product to decarburization annealing, said molten steel consisting essentially of not more than 0.02% C, 1.5 to 4.0% Si, not more than 1.0% Al, with the balance being Fe and unavoidable impurities, said hot rolling being done at a temperature in a range of from 900.degree. to 1100.degree. C.

Abstract: A method for preventing edge cracks in a grain oriented silicon steel sheet produced from a continuously cast slab containing 2.5 to 4.0% silicon. This method is carried out with a controlled reduction rate in a rough rolling mill and/or with an adjusted reduction by a pair of edge rolls of an edger.

Abstract: A method for treating a steel slab containing 2.5 to 4% Si to a temperature not lower than 1260.degree. C. in a continuous heating furnace of the walking-beam type, comprising; charging the slabs into the continuous heating furnace through its charge inlet, transferring the slabs by means of walking-beams in the furnace with the rear end of a preceding slab substantially contacting a front end of a subsequent slab under the condition that the contact time of the slab with fixed beams is not more than three times longer than the contact time of the slab with the transfer beams, and separating the adjacent slabs with a space sufficient to permit remelting of solidified slag adhered between the adjacent slabs approaching the extraction outlet of the furnace.
