Title: Manufacture of anisotropic permanent magnet
Inventor: YAHAGI SHINICHIRO
IPC: H01F41/02
Filed: 1989-02-07
Abstract: PURPOSE:To decrease processing temperature, and to obtain superior magnetic characteristics even in the case of using Nd instead of Pr by fining crystal grain of ingot of R-Fe-B system magnetic alloy, and performing hot working. CONSTITUTION:By heating ingot of R-Fe-B system magnetic alloy in hydrogen gas, hydrogen is occluded in the alloy, and hydride is formed. When the partial pressure of hydrogen in the atmosphere is decreased, the hydride is broken and hydrogen is emitted. Since this formation-decomposition of the hydride makes the crystal configuration fine, the magnetic characteristics can be improved by hot working. As to the R-Fe-B system alloy in the above process, Nd is used as R with the weight of 29-33% is combined into the composition of B:0.5-2.0% and residual Fe. It is desirable to add Co:1-20% thereto.

IPC: G01J5/14
Filed: 1989-02-09
Abstract: PURPOSE:To enable realization of a higher sensitivity by arranging a thermopile to be a series connection structure of pairs of p-type semiconductor resistance layers and n-type semiconductor resistance layers. CONSTITUTION:This sensor has a thermopile which comprises a series connection structure of a heat separation area 3 thermally separated from a substrate area formed with a thin part in a semiconductor substrate 1, an infrared rays absorbing layer 5 formed in the area 3, resistance layers 6 and 11 which are formed in the area 3 from the absorbing layer 5 to the substrate area. The thermopile 20 has a higher conversion efficiency of temperature difference- electromotive force utilizing both Seebeck effects of the resistance layers 6 and 11. This eliminates the need for providing a metal wire between the absorbing layer 5 an the substrate area thereby preventing a deviation in an optical alignment as caused by a drop in heat resistance and a deformation due to a bimetallic effect. The result is a larger temperature difference per unit incidence value of infrared rays to realize a higher sensitivity.
