Inventor: IINO TAKAYUKI
IPC: G01N21/00
Filed: 1993-08-06
Abstract: PURPOSE:To enable the measurement of the concentration of an excessive carrier of a half-insulating semiconductor at a room temperature free from the presence of free exciton emission by measuring changes in specific resistance of a half-insulating semiconductor with a specific resistance value exceeding a specified value by light irradiation. CONSTITUTION:A sample of a half-insulating semiconductor, for example, a half- insulating GaAs and a half-insulating CdTe with a specific resistance of above 1X10<7>OMEGAcm and with an electron mobility mu and a hole mobility mup known is formed in a rectangle desirably with a size of about 5mmX5mm and electrodes are formed at four tops of the rectangle to facilitate the measurement of changes in specific resistance. As the concentrations DELTAnp and DELTApp of an excessive carrier generated by the irradiation of light is given by DELTAnp=DELTApp as electrons and holes are generated in a pair and is determined by DELTAnp=4omicronpV/[piD<2>lambdaq(mun+mup)]. (wherein omicron: electric conductivity in light irradiation, q: electric element, V: sample volume, D: beam diameter of irradiation light, lambda: depth of irradiation light). This eliminates free exciton emission thereby enabling comparison of the intensity of emission between samples different in surface condition.

Abstract: PROBLEM TO BE SOLVED: To provide a gradient functional complex material, in which a compsn. ratio of a non-oxide ceramic is reduced and a compsn. ratio of a metal is increased toward inside from surface, and an interface between the non-oxide ceramic and the metal is absent. SOLUTION: A molding is obtained by molding a mixed powder of metal particles and non-oxide ceramic particles, and a porous sintered compact is obtained by sintering this molding. And further after impregnating a boron compd. contg. solution into the porous sintered compact, the prescribed porous sintered compact, which is impregnated the boron compd. contg. solution, is re-sintered. In this second sintering step, particle growth (making dense) of the non-oxide ceramic particle is accelerated by action of the boron compd. as sintering auxiliary. And the metal particles are pushing-moved by this particle growth and the metal particles are diffused to inside of the sintered compact. A compacted sintered compact (gradient functional complex material), in which concn. gradient of the non-oxide ceramics and the metal are generated, is obtained by this process.

Title: Bias tire
Inventor: ISOBE NAMIO
IPC: B60C9/02
Filed: 1982-11-11
Abstract: PURPOSE:To improve the productivity of a tire in a way of dispensing with a PCI process as well as to aim at improvements its durability upon a reduction in size growth in time of running, by using such a nylon coard as having a specific elongation percentage and a size stability index, as a reinforcing cord for a carcass layer. CONSTITUTION:A reinforcing cord for a carcass layer 1 of a bias tire has an elongation percentage E% in a range of 7.0<=E<=14.0 in time of receiving a load of 2.7g/denier and uses a 6 or 66 nylon cord in a range of 1.4<=D<=1.8 in terms of a size stability index D being expressed as the product of the elongation percentage E% and heat shrinkage stress g/denier. Since this low heat shrinkable nylon cord features that a reinforcing cord of its carcass layer 1 is small in shrinkage as well as intermediate elasticity E is also small enough, the PCI process required after vulcanization so far can be omitted. And, what is more, size growth in time of running is as small as negligible and ground contact pressure is uniformized whereby one-sided wear and a crack are much reduced, thus the durability of a tire is improved.
