  • Patent number: 8997815
    Abstract: According to one embodiment, an ultrasonic bonding apparatus includes an ultrasonic transducer, a distal-end tool, an ultrasonic horn and an ultrasonic oscillator. The ultrasonic oscillator includes an oscillation circuit and a control device. The ultrasonic oscillator applies the voltage oscillated by the oscillation circuit to the ultrasonic transducer. The control device is configured to detect a voltage reflection ratio from the voltage and current supplied from the oscillation circuit and to control the frequency of the voltage generated by the oscillation circuit, thereby to minimize the voltage reflection ratio.

  • Publication number: 20100087617
    Abstract: The present invention provides a thermosetting polyurethane elastomer that is yellowing-free, has low hardness and does not give rise to bleeding without using any plasticizer, has little tack, and exhibits small changes in hardness with temperature. This is achieved by a composition forming a yellowing-free, low-hardness polyurethane elastomer, containing no plasticizer and having (A) an isocyanate-terminated prepolymer and (B) a polyester polyol, wherein the isocyanate-terminated prepolymer (A) is an isocyanate-terminated prepolymer obtained by reacting hexamethylene diisocyanate with a glycol having an alkyl group as a side chain and having a molecular weight no greater than 500, and the polyester polyol (B) is a polyester polyol obtained from trimethylolpropane, 3-methyl-1,5-pentanediol and adipic acid, and having an average number of functional groups of 2.5 to 3.5 and a number average molecular weight of 800 to 5,000.
