  • Publication number: 20180261414
    Abstract: An electromagnetic relay includes a base, an electromagnet block fixed to the base, an armature which reciprocates when the electromagnet block is switched between an excitation state and a non-excitation state, and a card which slides in association with the movement of the armature. The base includes a rail portion which guides the card upon sliding, and the card includes a slide portion which slides along the rail portion. The rail portion includes a stopper portion which prevents disengagement of the slide portion from the rail portion.

  • Patent number: 8317758
    Abstract: A medical stopcock which allows easier switching operation of plural branch-tubes. The main body of the stopcock comprises a chamber part with a nearly spherical inner surface, and an upstream branch-tube, a downstream branch-tube and a merge-branch-tube all extending from the chamber part. A valve body of the stopcock comprises a nearly spherical valve main body and a rod-shaped operating part with a guide hole linking the inner surface of the chamber part to the outside. In operation, the rod-shaped operating part is moved along the guide hole through the use of the horizontal flow passages and the vertical flow passage to allow the predetermined branch-tubes out of the upstream branch-tube, the downstream branch-tube and the merge-branch-tube to communicate with one another or to shut-off the communication.

  • Patent number: 8177752
    Abstract: A medical tube set includes a tube and a stylet that improves the insertability of tube. The stylet structure comprises an inner core that can be inserted into the tube, an apical tip that is affixed to the apical end of inner core, and a movable expansion member that can move between apical tip of inner core and stop that is provided at a predetermined distance from apical tip. An engagement is formed at the posterior end of apical tip, and is able to engage the apical end of tube. By positioning movable expansion member within apical end of tube, apical end can expand radially outwards so that apical tip can pass through.

  • Patent number: 8046402
    Abstract: A signal processing method and apparatus reducing distortion using divided signals differing in only amplitude by weighting an input signal by first weights ki (i=1 to 4) to obtain divided signals, performing the same signal processing f(x) on the divided signals, weighting the signal processed divided signals by second weights l1 (i=1 to 4), and adding the divided signals Vout1 to Vout4 weighted by the second weights. The first weights are k1=t, k2=?t, k3=1, k4=?1, while the second weights are l1=?1, l2=1, l3=t3, l4=?t3. Here, t=b/a (where a and b are different positive integers).
