Title: Fixed memory circuit
Inventor: MASUDA KENZOU
IPC: G11C17/12
Filed: 1984-03-05
Abstract: PURPOSE:To accelerate a reading speed and at the same time to avoid a misreading by accelerating the precharging time of an output line of a memory cell containing many FETs connected in series. CONSTITUTION:FETM1-M3 function as the 1st precharging FET respectively and are controlled by a clock pulse phi1. While FETM4-M6 function as the discharging FETs and are controlled also by the pulse phi1. In addition, the 2nd precharging FETMp is provided and the pulse phi1 is impressed to the gate of the FETMp with its drain connected to a power supply terminal VGG and its source connected in common to the other end of each memory line respectively. In other words, these drain and source are connected in common to the source of the FET of the final stage among output lines B1-B3 of the FETs constituting a memory cell. Thus the FETs are precharged successively from the power supply side by impressing the pulse phi1 even through the FETs, e.g. >=120 units, constituting the memory cell are connected to an output line. At the same time, the precharge is carried out also from the final stage side via the FETMp.

Title: Manufacture of semiconductor
Inventor: WATANABE TETSUO
IPC: H01L21/322
Filed: 1980-03-31
Abstract: PURPOSE:To prevent deterioration of characteristics by thermally treating the back of a silicon wafer covered by Si3N4 and providing a flawless layer on the front and a defective layer which reaches the back below the flawless layer. CONSTITUTION:SiO22 is provided on P type Si substrate 1 and then is opened to receive a deposition 3 of Sb, thus covering the front and back surfaces with SiO24. Then Si3N410 is provided by removing the back surface film 4 and thickness is held down to approximately 1,000Angstrom  so that the generation of a bias in silicon and the increase of a differential in coefficient of thermal expansion are prevented. Next, it is treated in nitrogen at approximately 1,000 deg.C for 15hr or so to diffuse Sb3 deeply and thus form an imbedded layer 5. Following this process, Si3N410 is etched and the back of a silicon substrate 1 is etched approximately 2mum to remove Sb and getter impurities. Then SiO24 is removed and N- or P type Si layer 11 is epitaxially formed on the front to complete the imbedded diffusion layer 5. Inside the layer 11, a base and an emitter are provided. Under this constitution, oxygen is deposited (defect 7) on account of Si3N4 on the back of the substrate, resulting in the ''getting'' of gold. Thus a getter concentration is effectively reduced because the defective layer 8 extends from the center of the substrate to the back, so that the defective concentration lacking in quality is reduced, the rediffusion of a getter won't occur, improving properties.

Title: Porous refractories and its production
Inventor: NASHIKAZU HAJIME
IPC: B22D1/00
Filed: 1981-03-20
Abstract: PURPOSE:To perform floation of the nonmetallic inclusions in molten steel effectively in porous refractories to be installed in a molten steel vessel in order to form bubbles in molten steel by specifying the relations between pore sizes and the spaces among the pores. CONSTITUTION:The equationI(sigma: surface tension, g: gravity acceleration, rho: the specific gravity of molten steel, rhog: specific gravity of gas) holds for the diameters db of the bubbles formed from the pores of a diameter (d) of porous refractories, in accordance with water model experiment. Here, rho>=rhog and therefore if rho-rhog rho, the equation II is obtained. To prevent the bubbles formed from the pores from joining to the bubbles from the adjacent pores and from growing to large bubbles, it is necessary to make the spaces P among the pores larger than the diameter (db), that is, to satisfy the equation III. To produce such porous refractories, plural pieces of mask plates made of a thermofusible of combustible blank material of >=d diameter are placed by leaving >=P among  each other. Next, fluid refractories are coated on the blank body 3 of the spaces between the mask plates and these and mask plates are heated, whereby the mask plates are removed and the fluid refractories are sintered.
