  • Reflective photosensor and semiconductor light emitting apparatus each using micro Fresnel lens
    Patent number: 5130531
    Abstract: In a reflective photosensor in which a light emitting element and a light receiving element are disposed in a mold resin, a planar optical element (micro Fresnel lens) including a first lens section for projecting a light emitted from the light emitting element toward a sense object in an external space and a second lens section for introducing a reflection light reflected from the sense object to the light receiving element is arranged in the mold resin. Favorably, the light emitting element is a light emitting diode of an edge emitting type and is set in a posture in which the element lies on its side. A reflection mirror is disposed in the model resin to introduce a light emitted from the light emitting diode to the first lens section.

  • Optical pickup device
    Patent number: 5128915
    Abstract: A device for processing optical data comprising:an optical waveguide formed on a substrate,a light source for the laser beam to be admitted into the waveguide,lens means provided on the waveguide for causing the beam propagating through the waveguide to emerge obliquely upward and focusing the emergent beam two-dimensionally,means for receiving the beam reflected obliquely from above,a base provided with the laser light source, the substrate and the light receiving means,a focusing drive mechanism for adjusting the position of the base upward or downward, anda tracking drive mechanism for adjusting the position of the base laterally.

  • Coffee maker having a detachable cassette containing the pump and heater assembly
    Patent number: 4741259
    Abstract: In a coffee maker having a housing 1, a flow heater 6, a water reservoir 4 and a filter device 3 the flow heater is accommodated in a cassette 10 which is detachably mounted in the housing 1. By detaching the cassette from the coffee maker the electrical parts are completely separated from the housing. The detached cassette permits the housing of the coffee maker to be immersed in water during cleaning.
