Title: Characteristic measuring device
Inventor: KUROIWA KATSUHIKO
IPC: H01L21/66
Filed: 1989-03-15
Abstract: PURPOSE:To automate measuring processes of electric and optical characteristics and select the characteristics at high speed with high accuracy by measuring LD bar-like elements of respective semiconductor laser parts in strip bodies in such a manner that respective optical sensors move alternately. CONSTITUTION:A detection mechanism 34 (40-44) makes optical sensors 61 and 62 face on measured points alternately every each time a stage 1 performs a slide movement and then its mechanism detects output characteristics, far field patterns, and peak frequencies of a semiconductor laser. Consequently, in a single semiconductor laser part, the mechanism is allowed to perform characteristic checks of desired items by bringing once a probe needle 30 into contact with the laser part. This approach not only improves the working efficiency but also lessens possibilities of giving rise to any damage to the semiconductor laser part due to contact which is just made between its laser part and the probe needle. In this way, the semiconductor laser part causes monolithic strips 8 that are arranged in parallel to be used as samples; besides, respective characteristics of each semiconductor laser part are measured and selected.

Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery with high capacity and superior high rate discharge characteristic by improving the negative electrode containing a carbonaceous material. SOLUTION: A nonaqueous electrolyte secondary battery has a negative electrode 6 containing a carbonaceous material A, having an atomic ratio (H/C) of hydrogen (H) to carbon (C) of 0.1-0.4 and capable of absorbing/releasing lithium ions and a fibrous carbonaceous material B having an atomic ratio (H/C) of less than 0.1 and capable of absorbing/releasing lithium ions, and a solid-state or gel-state nonaqueous electrolyte. The smaller the atomic ratio (H/C) of the carbonaceous material is, the fine the structure approaches graphite structure is, the higher the velocity absorbing/releasing lithium ions and electronic conductivity becomes. Whereas the larger the atomic ratio (H/C) is, the greater the amount absorbing/releasing lithium ions is, the velocity absorbing/releasing lithium ions and the electronic conductivity tends to be decreased.  If the atomic ratio (H/C) exceeds 0.4, the carbonaceous material becomes difficult to release lithium ions.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic sensor improved in sign]al-to-noise ration and high in magnetic field sensitivity by detecting an external magnetic field based on tunnel resustances among magnetic substance layers and obtaining the difference between resistances which are complementarily changed under the external magnetid field. SOLUTION: An antiferromagnetic body layer 11 and an antiferromagnetic body layer 17 mutually reversibly pin the magnetization direction of a ferromagnetic body layer 12 and the magnetization direction of a ferromagnetic layer 16. Consequently, magnetoizations of the layer 12 and the layer 16 are pined to directions opposite with each other. The corrective force of a soft magnetic material layer 14 is small and the direction of magnetization of the layer 14 freely rotates according to the external magnetic field. The direction of the axis of easy magnetization of the layer 14 intersects the magnetization directions of theater 12, 16 roughly at right angles. Static magnetic fields by the layer 12, 16 are made to be canceled with each other on the layer 14 by adjusting ferromagnetic materials and the thichnesses of the layers 12, 16.  When resistances of respective tunnel junctions between the layer 16 and the layer 14 and between the layer 14 and the layer 12 are defined as r1 and r2, resistances r1, r2 are complenentarily changed by a spin tunnel phenomenon when the magnetization direction of the layer 14 is changed by the external magnetic field. Then, the difference of these changes is detected.
