Inventor: MORI AKIRA
IPC: B22F3/14
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To obtain a high strength target suppressing the generation of particles and suppressing the generation of the defectives of a dielectric film by subjecting multiple oxide powder contg. Pb, Zr and Ti or multiple oxide powder contg. Pb, La, Zr and Ti to hot pressing in a specified temp. range in a reducing atmosphere. SOLUTION: The temp. in the hot pressing is controlled to 845 to 900 deg.C, as the reducing atmosphere, particularly, a CO atmosphere is preferable, and the load to be applied is desirably controlled to 100 to 300 kg/cm2. In the case multiple oxide powder contg. Pb, Zr and Ti or Pb, La, Zr and Ti is hot-pressed in the reducing atmosphere, a part of the multiple oxide powder is reduced to obtain a target composed of a sintered body of the multiple oxide powder cong. Pb, Zr and Ti, and by executing sputtering using this target, the generation of particles caused by the sputtering is suppressed, and its mechanical strength is also made excellent. The deflective strength of the sintered body is preferably controlled to >=7 kgf/mm2.

Title: Preparation of needlelike coethite
Inventor: HAMAHATA TOSHIHIRO
IPC: H01F1/11
Filed: 1979-11-13
Abstract: PURPOSE: To obtain needlelike goethite suitable for preparing magnetic powder of high coercive force, by oxidizing a basic solution of a ferrous salt with a nitrate as an oxidizing agent at a given temperature or above.  
     CONSTITUTION: An alkali, e.g. NaOH, is added to a solution of a ferrous salt, e.g. ferrous sulfate, to adjust the pH to 11 or higher. The ferrous salt solution of adjusted pH is then allowed to stand for a given time, and the supernatant liquid is discarded to adjust the ratio between the anion and the ferrous ion of 1 or higher. The ferrous salt solution is then oxidized with a nitrate as an oxidizing agent at a temperature of 80°C or below to form a precipitate, which is filtered washed with water and dried to give needlelike goethite. The resultant goethite is suitable for preparing finely divided magnetic powder having high magnetic characteristics, particularly coercive force.

Abstract: PURPOSE:To permit a polling and to improve the reliability of a system with preventing carrier leak by providing a multi-stage attenuator which is controlled by a high speed switch between an oscillator and a trunk in a terminal equipment and providing an oscillation time control circuit. CONSTITUTION:A terminal equipment 11 is equipped with an oscillation circuit 12 which generates a carrier for the transmission of up data, and a data circuit 14 which outputs a data signal corresponded to data impressed on an input terminal and an oscillation time control circuit 17 terminates the oscillation of the oscillation circuit 12 when a control signal RTS is continuesd to be active for more than required maximum time. When the control signal is at low level, the output of the oscillation circuit 12 is inputted to a modulation circuit 15 without being attenuated at an attenuating circuit 13 and the data signal, after modulated, is sent to a center side from an amplifier 16 through the trunk. So that, when the control signal becomes high level, an oscillating output is attenuated at the attenuating circuit 13 and a carrier leak level leaked to a trunk side is made so much smaller, it is possible to prevent the up data transmission of other terminal equipments from the interference.

Title: Biosensor for measuring total vitamin b6
Inventor: ENDO HIDEAKI
IPC: C12R1/865
Filed: 1994-06-28
Abstract: PURPOSE:To measure the total vitamin B6 quantity in a sample quickly and simply by detecting a difference (current decrease value) between steady state current values obtained by dipping a microbial electrode in a buffer solution vessel and in a sample liquid vessel. CONSTITUTION:When a microbial electrode 2 formed by an oxygen electrode and a yeast Saccharomyces- ATCC9080 immobilized film is dipped in a buffer solution in a buffer solution vessel 3, after a while, a steady state current value A is obtained. Subsequently, when the electrode 2 is dipped in a sample liquid containing a base medium for vitamin B6 determination in a sample liquid vessel 4, though the current value is decreased, after a while, a steady state current value B6 is obtained. A difference between the measured current values A, B, that is, a current decrease value (sensor output) has a correlation to the vitamin B6 quantity (density) in the sample liquid, so that if a current decrease value in the sample liquid containing vitamin B6 of a known density is previously measured to create a working curve, the total vitamin B6 quantity in a sample liquid of an unknown density can be measured.
