  • Publication number: 20080101431
    Abstract: The laser radiation apparatus is provided having substantial light emission intensity although the laser radiation apparatus is miniaturized. A solid state laser rod; the excitation light source formed such that the excitation light source surrounds an emission axis in a section perpendicular with respect to the emission axis of laser light of the solid state laser rod; and a lens barrel placed so that the lens barrel surrounds the excitation light source and condenses light from the excitation light source to the solid state laser rod. Excitation light reflected upon inner surface of the lens barrel is radiated uniformly over the lateral surface of the laser rod so that laser active medium is efficiently excited, and energy conversion rate is improved.

  • Patent number: 7157995
    Abstract: An electromagnetic relay has an iron core having a protruding shaft and a magnetic pole portion. The protruding shaft is penetrated through a through hole provided on a metal case, and coil is wound around the protruding shaft. A voltage is applied to the coil for magnetization and stopped for demagnetization, hence to drive a contact mechanism with a movable iron piece that is attracted by and separated from the magnetic pole portion, thereby causing a reciprocating motion of the movable iron piece. The relay can prevent generation of eddy current.

  • Patent number: 7023306
    Abstract: An electromagnetic relay includes an electromagnet block having coils wound about the bodies of spools through which iron cores are provided. The electromagnet block is accommodated in a concave part that opens upward of a box-shaped case such that the shaft centers of the iron cores can be orthogonal to the bottom surface of the box-shaped case. The electromagnet block is excited and demagnetized by the passage and break of electric current through the coils so that a contact mechanism can be driven by a movable iron piece that is absorbed to and leaves magnetic pole portions at the upper ends of the iron cores. In this case, the electromagnet block is hung at the upper opening edge of the box-shaped case such that a space can be provided between the bottom surface of the box-shaped case and the electromagnet block.

  • Publication number: 20050146405
    Abstract: It is to provide an electromagnetic relay that can perform the return operation of a movable iron piece quickly, free from a fear of welding the contact. In the electromagnetic relay, an iron core is penetrated through a through hole formed on the bottom surface of the aluminum case and coil is wound around the shaft of the protruding iron core. Through applying a voltage to the coil for magnetization and stopping the voltage for demagnetization, a contact mechanism is driven with a movable iron piece that is going and returning, attracted by and separated from a magnetic pole portion of the iron core. In particular, a slit for preventing generation of eddy current is provided on the opening end of the through hole.
