Title: Production of titania fiber
Inventor: FUJIKI YOSHINORI
IPC: C01G23/047
Filed: 1984-06-01
Abstract: PURPOSE:Titanium slag which is formed on the production of pig iron from ilmenite is used to utilize an impurity contained in it whereby titanium fiber is obtained. CONSTITUTION:Titanium slag and naturally occurring rutile or anatase sand are mixed in such an amount as the former is less than 3/1 in weight. When the resulting mixture is represented in formula I, it is mixed with potassium oxide or a compound forming the same by heating (in some cases, a mixture of both) so that the mixture meets the formula II, then melted by heating. Fibrous material of layer-structured crystals which is same as potassium dititanate of formula III is formed from the melt, treated with an acid to extract potassium component to form crystalline titanate fiber. Then, the fiber is heat-treated at a temperature over 500 deg.C, but lower than the melting point to give the objective titania fiber.

Title: Semiconductor device
Inventor: FUTAMI HARUJI
IPC: H01L29/866
Filed: 1980-08-19
Abstract: PURPOSE:To obtain a diode excellent in the noise characteristics and low in the operational resistance by providing a P<+> layer to be connected to a P<+> buried layer having an N epitaxial layer laid on a P layer with an N<+> buried layer while an N<+> layer is provided on an N epitaxial layer on the surface of the P<+> layer. CONSTITUTION:An N epitaxial layer 28 is made over an N<+> buried layer 27 provided on a P type substrate 26 and an N epitaxial layer 30 is made after a P<+> layer 29 is buried into the layer 28. When the epitaxial layers 29 and 30 are isolated by the P<+> layer, a P<+> layer 32 and an anode P<+> layer 33 are made to lead the anode electrode. Then, N<+> layer 34 is provided to attach electrodes 35 and 36 thereto. In operation, current flows vertically through a P-N junction 37 with a large sectional area hence not so big in the current density. Neither concentration of electric field nor heat generation occur on the surface of the substrate, meaning a high immunity to breakdown. As noise is reduced as generated at the center of re-connected section near the surface while the buried layers 29 and 27 are kept out of contact, there is no increase in the resistance of the P<+> buried layer 29 thereby minimizing the operational resistance. Thus, a Zener diode with a higher withstand voltage is obtained without additional process.

Filed: 1990-04-27
Abstract: PURPOSE:To extend the detecting range of a movement vector without the broad extension of circuits by correcting the average space gradient of a present screen and a previous screen by a density difference operating means. CONSTITUTION:Picture signals (g) inputted to an input terminal 10 are divided into three routes, firstly, a time gradient (d) is calculated, secondly, a space gradient gd2 within the present screen is calculated and thirdly, a space gradient gd1 within the previous screen is calculated. Besides, an optimum averaging circuit 30 executes optimum weighting to the space gradients gd1 and gd2 of the previous screen and the present screen and averages them. Then, a multiplier 28 multiplies the output of a code output circuit 26 to the output of a subtracter 20 of the time gradient (d). Thus, for the previous screen and the present screen, the average space gradient is found under the fixed weight. Thus, also on a picture of which the space gradient time-changes, a more precise movement vector is detected and application is attained also to the picture of which movement is large.

Abstract: PROBLEM TO BE SOLVED: To reduce consuming area, to improve the stability, to attain a high convergence speed and to avoid problems for mount and correspondence to a design change by adopting a digital circuit for a clock oscillator. SOLUTION: A delay element chain 20 is formed by connecting an array of 2-stage inverters 22 as a delay element in series. A delay element selection section 30 such as a shift register to store bits to indicate a selecting state is connected to each array of the inverters 22 as a means to select a desired array of the inverters 22.
