Title: Optical transmission line
Inventor: KURAUCHI NORITAKA
IPC: G02B6/32
Filed: 1985-06-03
Abstract: PURPOSE:To use even an optical fiber having the small number of apertures as an optical transmission line having the large number of apertures by connecting one end of a lens, which has one end formed into a flat surface and has the other end formed into a convex three-dimensional curved surface and has the refractive index reduced gradually toward the other end from one end in the lengthwise direction, to the end face of an optical fiber. CONSTITUTION:The refractive index of a numerical aperture converting convex lens 2 in a plane vertical to an optical axis 4 is equal in the center part and the peripheral edge part, and the refractive index in the axial direction is raised gradully toward the exit end face, which is connected to an optical fiber 3 for communication, from an incidence end face 1. A light 5 made incident on the convex of the lens 2 at an incident angle theta is so bent that the angle of the light to the optical axis 4 is reduced, and this light is made incident on a core part 6 of the optical fiber 3 for comminication at an exit angle considerably smaller than the incidence angle theta. Consequently, the light having a maximum incidence angle, which is prescribed by the number of apertures of the optical of the optical fiber 3, or large can be led to the core part though the number of apertures of the optical fiber is smaller than that of the incidence end face 1 of the convex lens 2.

Title: Cordless telephone set
Inventor: KAMIYA SHIN
IPC: G10L15/00
Filed: 1992-05-12
Abstract: PURPOSE:To dial a correct telephone number to a telephone line with a voice dialer even when a telephone set at registration differs from a telephone set at dialing. CONSTITUTION:An electronic switch 32 switches an inputted voice signal and inputs the signal to a voice recognition section 13. A control section 33 outputs a telephone set number representing an input telephone set. A voice recognition section 13 registers a standard pattern of a registered word with the telephone set number added thereto to an internal memory corresponding to the telephone number at registration. On the other hand, when a telephone number of the standard pattern representing a minimum matching distance with a characteristic pattern of an inputted word differs from a telephone set number of the characteristic pattern at the time of dialing, a reject threshold level is set to a 2nd threshold level higher than a usual 1st threshold level. When the telephone set for registration/dialing differs from each other in this way, the reject threshold level is increased to prevent decrease in the recognition rate of the voice recognition section 13 and transmission of the correct telephone number by a voice dialer is attained.
