Title: Production of alumina having high purity
Inventor: IWASE KOJI
IPC: C01F7/46
Filed: 1988-05-25
Abstract: PURPOSE:To obtain alumina having high purity by calcining raw material alumina at a specified temp. under a specified pressure according to impurity component to be removed. CONSTITUTION:The raw material alumina is calcined at >=800 deg.C and <=0.5atm reduced atmosphere according to impurity component to be removed to obtain the targeted alumina. Further, when the raw material alumina is corpuscular alumina having <=5mu mean particle size, the corpuscular raw material alumina is coated with carbonaceous substance in advance, thereafter calcined at >=800 deg.C under <=0.5atm reduced atmosphere according to impurity component to be removed and then, decarbonized by heating in an oxidative atmosphere under the atmospheric pressure to obtain the corpuscular alumina having high purity. When some kinds of impurities coexist and they must be removed at the same time, the degree of difficulty of removal by applying the method above- mentioned is Na2O>Fe2O3>SiO2>MgO>CaO and Na2O can be the most easily removed.

Title: Production of high-purity silica
Inventor: SEKI AKIRA
IPC: C01B33/193
Filed: 1987-05-25
Abstract: PURPOSE:To obtain a high-purity silica having an impurity content of lower than a specific level, in a short time at a low cost, by pouring an aqueous solution of an alkali silicate adjusted to a specific viscosity into a mineral acid to extract the impurities into the mineral acid solution and washing the precipitated silica with a mineral acid. CONSTITUTION:Viscosity of an aqueous solution of an alkali silicate (e.g. water glass) is adjusted to 10-10,000 poise e.g. by polymerization with dehydrative concentration process. The adjusted aqueous solution of alkali silicate is directly poured into a mineral acid (e.g. dilute sulfuric acid) to extract the impurities in the alkali silicate into the mineral acid solution and, at the same time, to produce precipitate of silica. The precipitate is separated by filtration, washed with a mineral acid and then with water. The resultant water-containing silica is dried and calcined to completely remove the water. A high-purity silica having a total impurity content of <=5ppm can be produced by this process. The silica is suitable as optical material, electronic material, etc.

An adder 1001 adds 1 to an input from the frequency of occurrence memory 11 into an integration section 1000 and the output is latched by a latch 1002. Thus, the frequency of occurrence of the multi-level picture data corresponding to the binary pattern of 3X3 pic ture elements around each of all picture elements of an input picture is formed in the frequency of occurrence memory 11. The output of the frequency of occurrence memory 11 is outputted to an adder 17 and a latch 18, which repeats latching synchronously with a counter 13 and the result is being added by the adder 17 thereby obtaining finally SIGMAn (D)=sum.

Abstract: PURPOSE:To easily perform the maintenance work by providing L-shaped holes and providing claws which are closed to the inside till passing holes but are opened to the outside and are engaged with and electrically connected to earth patterns after passing holes at the time of insertion from the surface side of a printed board. CONSTITUTION:Earth patterns 1b are provided on the rear face around L-shaped holes 1c in a printed board 1; and hen insertion parts 7a are inserted to holes 1c from the surface side of the printed board 1, claws 7b are closed to the inside till passing holes 1c, and they are opened to the outside and are engaged with and electrically connected to earth patterns 1b after passing holes 1c.

Title: Webbing takeup device
Inventor: NAGATA TOMONORI
IPC: B60R22/46
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a webbing takeup device capable of taking up a webbing belt forcedly and effectively. SOLUTION: A plurality of projections 54 are formed on the inside surface of a bearing body 52 to bear a major diameteric portion 28 of a takeup shaft 20 and make linear contact with the periphery of the portion 28 so that the bearing body 52 bears the portion 28 indirectly through the projections 54. Because of this linear contacting as mentioned, the contacting area is very small, and plastic deformation of the projections 54 can take place easily owing to the frictional resistance between the projections 54 and major diameteric shaft portion 28. This lessens the resistance to form an obstacle for the rotation of the portion 28, and the gas pressure can effectively be used to the rotation of the takeup shaft 20.

Abstract: PURPOSE:To eliminate the need of a control from the outside and to efficiently execute the test work of a logical characteristic by stopping an output of a logic signal of a pattern signal generating means until an external input signal is varied in response to a delay signal. CONSTITUTION:In the case a delay which extends over between periods of an output signal is predicted, '1' is written in a prescribed address of a delay pattern in advance. As a result, a reference clock given to an address generator 15 is stopped until a variation appears in the output signal, and an output of a logic signal SL from an pattern memory 11 is stopped. Therefore, it becomes unnecessary to execute an interrupting operation by a pattern controller 6 by applying a control signal SC from the outside, the generation of a program of the control signal SC applied to the pattern controller 6, and the setting process of a rate delay time are also unnecessary, and the test work of a logical characteristic can be executed efficiently.
