摘要:
A copper base alloy for terminals that is superior in all aspects of tensile strength, spring limits, conductivity, and stress relaxation characteristics can be produced by a process repeating the cycles consisting of hot-rolling, cold-rolling and annealing, in which process an ingot is prepared by melting and casting an alloy containing 1.0-3.0 wt % Ni, 0.02-0.15 wt % P. 0.5-2.0 wt. % Sn and, as an optional component, 0.01-2.0 wt % Zn, with the balance being Cu and incidental impurities, and with the ratio of weight percentages of Ni to P being within the range of 10-50%.

A copper base alloy for terminals that is of the Cu-Ni-Sn-P or Cu-Ni-Sn-P-Zn system and that has a tensile strength of at least 50 kgf/mm.sup.2, a spring limit of at least 40 kgf/mm.sup.2, a stress relaxation of not more than 10% and a conductivity of at least 30% IACS is provided. Terminals the spring portion or the entire part of which is produced from that copper base alloy, having an insertion/extraction force of 0.2-3 kgf and a resistance of not more than 3 m.OMEGA. at low voltage and current as initial performance, with the added characteristic that the terminals will experience not more than 20% stress relaxation are also provided. The alloy is superior to the conventional bronze, phosphor bronze and Cu-Sn-Fe-P alloys for terminals in terms of tensile strength, spring limits, stress relaxation characteristic and conductivity and, hence, the terminals manufactured from those alloys have higher performance and reliability than the terminals made of the conventional copper base alloys for terminals.

A cradle receives RF signals, performs level control of the RF signals, and emits the RF signals to a main-body unit installed to the cradle. When the main-body unit is installed, the cradle receives a video signal from the main-body unit, applies signal processing to the video signal, and then outputs it. Concurrently, the cradle outputs power-supply power to the main-body unit. Further, the cradle performs level control of the received RF signals to a first level when the main-body unit is installed, and performs level control of the received RF signals to a second level higher than the first level when the main-body unit is not installed.
摘要:
Using an image signal acquired by picking up a sample to be inspected by a color video camera, penetrant inspection and magnetic-particle inspection, which are non-destructive inspections, are carried out so that deficiency candidates, including a pseudo deficiency, are automatically detected and displayed on a screen. A real deficiency can be detected from the displayed deficiency candidates. As image data is stored in memory means, information of a deficiency can be repeatedly reproduced on the screen. In the penetrant inspection, the chromaticity at each position on an image is acquired, a deficiency candidate is extracted based on the chrominance, and the deficiency is distinguished from a pseudo deficiency based on the differential value of the chrominance. A polarization filter eliminates regular reflection originating from illumination in the penetrant inspection, and an ultraviolet-rays cutting filter prevents noise in the magnetic-particle inspection. Both inspections can be carried out with a single probe.

According to one embodiment, an radar apparatus includes a signal processor, a transmitting unit, an antenna, a first receiving unit, and a second receiving unit. The signal processor generates first or second pulses, and generates a control signal having first or second states. The transmitting unit converts the first and second pulses into first and second transmission pulses. The antenna radiates the first and second transmission pulses and receives reflection pulses to generate a reception signal. The first receiving unit includes first and second receiving circuits which processes the reception signal to generate first and second processed signals, respectively, and outputs one of the first and second processed signals depending on the state of the control signal. The second receiving unit processes the one of the first and second processed signals.
摘要:
The present invention relates to a method for inspecting a crack in a metal surface or the like, and, particularly, to an inspection method and apparatus for nondestructive inspection such as liquid penetrant inspection and magnetic particle testing. The present invention provides a flaw inspection method that essentially comprises the steps of illuminating a surface of a sample to be inspected, obtaining an image of the surface, characterizing a potential flaw on the inspected surface by processing the obtained image, displaying an image of the potential flaw, verifying that the potential flaw is a true flaw, and storing an image of the verified flaw in memory.
