  • Patent number: 7918572
    Abstract: An indicator device includes a light emitting element for emitting light, and a light conducting plate having a light incidence surface for conducting light from the light emitting element inside thereof and a light output surface, for a lighted indication by the light output surface. The light conducting plate has a triangular recess recessed to form with prescribed recess depths in one planer surface thereof, for light from the light emitting element to be reflected in part. The triangular recess has a recess extremity constituting a single vertex disposed in position on an optical axis of the light emitting element and nearer to the light incidence surface than other end parts thereof. The recess depths becomes shallower as the V-form recess extends from the recess extremity, allowing for an evenness of luminance of light over the light output surface formed on the light conducting plate.

  • Publication number: 20060207899
    Abstract: A sender golf bag for storing golf clubs allowing the golf clubs to be held at specified positions, a specified one of these golf clubs to be removed at a glance, and the golf clubs to be stably held to prevent damage, comprising a body and a cover body. The body further comprises an opening part vertically formed from the generally upper to the generally lower end of the slender bag and having rigidity to retain its original shape, a golf club holding means holding and storing the golf clubs, and a connection means installed near the opening part to contribute to the easy attachment/detachment of a cover body. The cover body covering the body further comprises an opening part formed in a shape matching the opening part of the body and having rigidity to retain its original shape and a connection means matching the connection means of the body to contribute to the easy attachment/detachment thereof.
