Title: Production of oxide superconductor
Inventor: OTOMO AKIRA
IPC: C04B35/45
Filed: 1989-03-29
Abstract: PURPOSE:To obtain a superconductor having a high critical temp. and a high critical current density by specifying the volume fraction and compsn. of a solid phase in a melt when part of an oxide consisting of Bi, Pb, Sr, Ca, Cu and O is melted by heating. CONSTITUTION:At least part of an oxide consisting of Bi, Pb, Sr, Ca, Cu and O is melted by heating and the oxide is held at a temp. at which a superconducting phase is formed for a certain time to produce an oxide superconductor. In this method, the volume fraction of a solid phase contained in the resulting melt is regulated to 1-20% and a Ca-contg. oxide is formed as the solid phase. The dispersibility of the oxide is improved, 110K phase is easily formed and segregation is avoided. At >20% volume fraction, a large amt. of the unreacted part remains, the compsn. of the superconductor is not uniform and the critical current density (Jc) does not increase. At <1% volume fraction, the Jc does not increase because melting proceeds excessively of the critical temp. does not increase because the separation or segregation of the solid phase proceeds. The presence of Ca and the volume fraction of the solid phase can be confirmed by analyzing a rapidly cooled sample.

Consequently, the deformation of the breaker layer 13 can be restrained at the minimum level.

Filed: 1990-03-27
Abstract: PURPOSE:To simplify manufacture, and to measure a wide frequency band with high sensitivity of current flowing to a conductor by employing a saturable magnetic sensor in which a pair of parallel cores having detecting coils wound thereon. CONSTITUTION:High frequency signals are always applied from an AC generator 11 to detection coils 19a, 19b of a magnetic sensor 13 as AC exciting currents, and cores 18a, 18b are always magnetized to saturated range. Accordingly, the sensor 13 is of a saturable type, and the amplitude of the output signal has a predetermined value to be determined by a saturated magnetic field. When a current I flows to a conductor 17, a magnetic field is generated in a direction to be determined by the current, added to or subtracted from the saturated field, its output waveform is shifted up or down, and it is output by a voltage detector 15 to measure the current I. The direction of the field generated by the current I in the cores 18a, 18b is reverse. Even positional relationship of the conductor 17 to the cores 18a, 18b is deviated, a measuring error caused thereby is automatically corrected.

Filed: 1978-06-28
Abstract: PURPOSE: To improve oil supply to the bearing surface and eliminate anomalous phenomena such as temperature rise on the surface, by making an outlet of oil exhaust port below an oil thrower.  
     CONSTITUTION: Bearing oil 29 in a clearance A is exhausted, because of the revolution of a shaft 21, from an oil exhaust port 33 in an oil thrower into an oil tank 30, thus preventing the oil from leaking from the upper end of an oil receiver 26. Bearing oil 29 exhausted from the exhaust port 33 is controlled to flow from the lower side of the oil thrower toward below the oil tank 30, and the oil 29 at the lower end of the bearing surface B is kept stable, oil supply to the surface B not being disturbed. Thus the formation of oil film on the bearing surface B is improved, without generation of anomalous phenomena such as temperature rise.

Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring a semiconductor device for measuring a twist angle when implanting impurity ions into a semiconductor wafer. SOLUTION: A gate electrode 12 is used as a mask for implanting ions and impurity ions are implanted onto the surface of a silicon wafer 16, thus forming a drain region 14 and a source region 15. At this time, the impurity ions are implanted obliquely for the silicon wafer 16, and parts (offset regions) 14a and 15a where the regions 14 and 15 are not formed are generated at the inside and outside of the gate electrode 12. Since the offset regions 14a and 15a have a high electrical resistance, a high electric field is generated between the offset regions 14a and 15a and a hot carrier is generated when a specific voltage is applied between the source region 15 and the drain region 14. By examining the position of the hot carrier, the dimensional shape of the offset regions 14a and 15a can be recognized and a twist angle can be measured.
