    摘要: In a resinous circuit board having a circuitized substrate having conductive layers therewithin, a plurality of pin pads formed on a rear surface of the substrate, and a plurality of pins, each pin having a tip end portion and a head portion and soldered to the pin pad in such a manner as to contact at the head portion to the pin pad. The head portion of the pin consists of a flange section which is larger in diameter than the tip end portion, and a part-spherical abutment section bulging from the flange section in the direction opposite to the tip end portion and brought into contact with the pin pad. The part-spherical abutment section is made of eutectic silver solder which is lower in melting point than solder such as Sn—Ag solder which is used for soldering the pin to the pin pad. Since the silver solder and soft solder are present between the flange section and the pin pad, they can release the stress applied to the pin, thus making it possible to increase the joining strength considerably. Further, the above structure can dispense with holes which are formed in the circuitized substrate and in which pins are press-fitted and fixed as in the prior art circuit board.

    摘要: An olefinic thermoplastic elastomer composition which does not exhibit problems due to a softening agent such as an oil is superior in molding processability. The thermoplastic elastomer composition is produced by a heat crosslinking process of a resin-rubber composition that contains an olefinic and/or diene rubber, an olefinic resin, and a vinyl copolymer. The vinyl copolymer is obtained by copolymerizing 20 wt % or more of a vinyl monomer represented by CH2═CHOCOR1 or CH2═CHOR2 wherein R1 and R2 are alkyl groups having 1-6 carbon atoms. The thermoplastic elastomer composition can include a vinyl copolymer that has not undergone a heat crosslinking process.

Also provided is a manufacturing method for a single crystal of calcium fluoride having its optical properties improved through an annealing process such that, its maximum temperature during the thermal process is set to a first temperature which is within the range of 1020 to 1150° C., and which is maintained for a designated period of time, and its cooling speed for reaching a second temperature, which is in the range of (or around) 600 to 800° C., from said first temperature is set to be 1.2° C./hour or less, or its cooling speed for reaching a second temperature, which is in the range of (or around) 700 to 900° C., from said first temperature is set to be 1.2° C./hour or less.

    摘要: A binocular has a focusing mechanism and a convergence angle correction mechanism. Focusing is achieved by moving an objective optical system or eyepiece optical system along an optical axis. The convergence angle correction mechanism, which is interlocked with the focusing mechanism, decenters an element of the objective optical system translationally with respect to the optical axis. The translational decentering is achieved by moving the objective optical element in a direction at an angle to the optical axis.
