Title: Magnetic field generator
Inventor: OGATA MASAO
IPC: A61B5/055
Filed: 1987-04-24
Abstract: PURPOSE:To obtain a uniform distribution of a magnetic field in a prescribed region, by forming central and peripheral parts of each main pole piece more thickly than its intermediate part and besides by forming this intermediate part in such thickness that the essentially uniform distribution of the magnetic field is obtained perpendicularly to an axis in the prescribed region. CONSTITUTION:Yokes 4 are disposed on the periphery of a pair of permanent magnets 2, and pole braces 8 are used to magnetically couple both yokes 4, 4, and a main pole piece 5 is fitted to an inner periphery of each permanent magnet so as to form a magnetic circuit. Thereupon, a magnetic field is generated axially in the permanent magnet 2 in a measurement part 3a which exists in the central part of a space 3. A central part 5a of each main pole piece 5 is formed thickly, and its peripheral part 5c is formed in a step projecting shape so that a magnetic flux generated from the permanent magnet can be effectively concentrated at the part 3a of the space 3 where a specimen is measured. An intermediate part 5b between the central part 5a and the peripheral part 5c is formed essentially uniform in thickness (t) over the whole. When the thickness (t) of this intermediate part is made appropriate, uniformity in intensity and distribution of magnetic field can be obtained in a prescribed region of a space.

IPC: G01L1/00
Filed: 1988-04-25
Abstract: PURPOSE:To effectively reduce noise by forming shielding plate like patterns on a part of a substrate so that an input side wiring part of a non-inversional amplifier formed in an integrated circuit is electrostatically shielded. CONSTITUTION:The shielding plate-like patterns 25, 26 are formed on an intermediate substrate in a multi-layer ceramic substrate consisting of ceramic substrates 11-15, an integrated circuit 16 and an input pin 17. Thereby, the input side wiring parts of operational amplifiers OP1, OP2 to be the input side of the non inversional amplifier are electrostatically shielded. In addition, the patterns 25, 26 are respectively connected to the feedback points, e.g., points A, B, of the non-inversional amplifier. Therefore, floating capacity existing in the wiring patterns and the input pin 17 of the non-inversional amplifier is equivalently reduced.

Title: Crucible with electrode
Inventor: KANEKO MINORU
IPC: G01N25/04
Filed: 1994-04-15
Abstract: PURPOSE:To secure safety when used within a manned space station, and enhance the degree of setting conditions by housing a pot main body in a plurality of transparent ampules in a closed end hollow shape each one end sections of which are opened. CONSTITUTION:When the pot main body 3 is covered by the ampules 4 and 5 of a double structure, specimen 11 in a molten state is prevented from leaking outside by the second ampule 2, at the outer side even if the first ampule 5 is damaged, so that safety is thereby enhanced. Besides, the air tightness of the ampules 4 and 5 is enhanced, even if material high in vapor pressure is fused, possibility for its vapor to leak outside is thereby lowered. Since there exists a closed space between both the ampules 4 and 5, the environment of each ampule 4 and 5 can be independently set, the environment of the pot itself can be adjusted to a test condition. Since the ampules 4 and 5 are transparent, and conductors 17a through 17c, and 17a' through 17c' are projected out of the side identical to the longer direction of the pot main body 3, handling when used is made more easy, and moreover, the entire length of the pot can thereby be shortened.

Abstract: PURPOSE: To realize the vector syntesis phase modulator easy for design and adjustment and strong in the oscillation proof, by the 90° phase shifter and the adder using operational amplifiers.  
     CONSTITUTION: The modulation signal V s  fed to the input terminal 1 is inputted to the integration circuit consisting of the operational amplifier 3 and obtains the signal V' s  delayed in phase by 90° as the output. This phase shifted modulation signal V' s  is added and synthesized with the carrier signal Vl fed from the terminal 5 at the adder consisting of the input resistors 6 and 7, operational amplifier 8 and feedback resistor 9. At the output side of the operational amplifier 8, each signal is phase-shifted by 90° being V" s  and V"l. The signal synthesized in vector is V 0 . Accordingly, the phase of the output synthesized vector is changed by keeping the carrier signal vector V'l constant and changing the modulation signal vector V" s  greater, smaller, positive or negative. Accordingly, as the circuit can be constituted as the solidstate, the vibration proof is excellent.
