摘要:
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.
摘要:
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.
摘要:
A lumbar support plate which is supported movably in a front/rear direction in a back frame that supports a headrest, and a biasing member which supports the lumbar support plate, are provided. A clutch mechanism which enables an output member to rotate by a rotating operation of a handle shaft, and an adjustment member which is capable of adjusting the front/rear position of the lumbar support plate in relation with an output member of the clutch mechanism are also provided. Also provided is a linking release mechanism which temporarily releases linkage with the clutch mechanism and permits rearward movement of the lumbar support plate, when a load equal to or greater than a prescribed value is applied to the lumbar support plate.

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.

The present invention provides novel polyaminopyridines which are excellent in solubility in various solvents, and are preferably used in a polymer-type organic electroluminescent material, and a process for preparing the same. More particularly, the present invention provides polyaminopyridines having a repetition structural unit represented by the following general formula (1); and having a number average molecular weight in a range of 500 to 1000000.
摘要:
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.
摘要:
A vehicle seat has a back frame, an elastic member interconnecting side supports of the back frame, a movable member on the elastic member, and a restriction on the back frame. The movable member and the restriction engage each other in a first mode when a rearward load on the elastic member is less than a given value and are released from one another in a second mode when the load on the elastic member equals or exceeds the given value. The restriction restricts a rearward movement of the movable member in the first mode to limit rearward bending of the elastic member. Rearward movement of the movable member is permitted in the second mode to release the limitation on bending of the elastic member. Thus, the vehicle seat protects an occupant's neck during a rear collision.
