IPC: G02B6/00
Filed: 1983-09-02
Abstract: PURPOSE:To obtain the titled rod capable of giving a fiber having excellent characteristics from an inexpensive material, easily, in a short time, by heating a quartz rod containing a dopant having low refractive index, thereby effecting the evaporation of the dopant from the inner surface and collapsing the quartz rod to a solid rod. CONSTITUTION:A clad layer containing F is applied to the inner surface of the natural quartz rod 1 by depositing an F-containing SiO2 soot to the inner surface of the quartz rod 1 and melting and vitrifying the soot. The supply of the raw material gas of glass is stopped, argon gas is introduced into the quartz rod 1, and the quartz rod 1 is heated at about 200 deg.C by moving the burner while applying internal pressure to the tube with the argon gas. The dopant F at the inner surface of the clad layer 2 is evaporated by the heat-treatment, and at the same time, the diameter of the tube is decreased to form a pure quartz layer forming the core part at the inner surface of the clad layer 2. Finally, the supply of the argon gas to the quartz rod 1 is stopped, and the shrunk quartz rod 1 is solidified by heating at about 1,800 deg.C to obtain the objective preform rod.

Filed: 1993-07-01
Abstract: PURPOSE:To erase data with a word line unit and to shorten a data rewriting time by providing source lines connected commonly to source of storage elements being on two work lines separatedly for every word line. CONSTITUTION:Prescribed voltages are impressed on a drain, a control gate and a source by selecting a bit line BL2, a word line WL2 and a source line SL1 in order to perform the write-in to a memory transistor M22. Consequently, electrons are implanted into a stray gate by the tunnel effect to raise the threshold voltage of the transistor M22 and the current is prevented from flowing through between the source and the drain and data are stored. At the time of erasing data, a11 bit lines BL0 to 3 and word lins WL1, 2 corresponding to a source line SL1 to be erased are grounded and a high voltage is impressed on the SL1. As a result, electrons are released from stray gates of transistors being on the work lines and then data are erased. Thus, the data rewriting is performed in a short time.

IPC: B22D11/128
Filed: 1989-06-28
Abstract: PURPOSE:To manufacture a good cast slab without developing buckling at short side part even in comparatively light rolling reduction by giving roll crown having the similar shape as recessed part in inner wall of long side and gradually reducing the crown rate to zero as it goes downstream. CONSTITUTION:At first, the cast slab 3 is cast in a continuous casting mold 1 so that thickness T0 at center part thereof is thickener than thickness T1 at edge parts and the rolling reduction is executed until the thickness at the center part of cast slab 3 is made to equal as the thickness T1 at the edge parts in the process during which solidification progresses. Therefore, by setting the thickness T1 at the edge part to the thickness corresponding to that of the finished cast slab in consideration of solidifying shrinkage rate, in order to obtain the cast slab 3 having the prescribed thickness, the rolling reduction is executed only to the center part of cast slab. Therefore, even in the cast of applying the rolling reduction at the end stage of solidification, the finished cast slab can be formed with extremely little value of the rolling reduction force. That is, as it is unnecessary to execute the rolling reduction to the solidified part at the short side part in the solidified shell, there is no apprehension to develop the buckling double fold, and the rolling reduction force can do with the light rolling reduction for deforming only the shell at unsolidified part.
