IPC: G01D5/36
Filed: 1988-09-13
Abstract: PURPOSE:To obtain sine waves having no distortion on light receiving surfaces of light receiving elements by providing a compensating plate having a refractive index different from that of air in an arbitrary optical path from a light source to the light receiving elements. CONSTITUTION:Light receiving elements 31 and 32 are provided in corresponding to slit trains S1 and S2 of different pitches provided in a code plate 1. A compensating plate 4 made of glass is provided between the slit train S2 and element 32. A light source 2 has a width sufficient to simultaneously irradiate the two slit trains S1 and S2 and a length W adjusted to the pitch P1 of the slit train S1. Positional relations between the light source 2 and elements 31 and 32 are adjusted against the slit train S1 and the light intensity distribution on the light receiving surface of the element 31 is set to a distortion-free sine wave distribution. Since the compensating plate 4 is provided between the slit train S2 and element 32, the rays of light passed through the slit train S2 are refracted and a distortion-free sine wave distribution can be obtained as the light intensity distribution on the light receiving surface.

Title: Modulating/demodulating circuit and communication system using this circuit
Inventor: MIYAGAWA SHOZO
IPC: H04L27/04
Filed: 1991-09-10
Abstract: PURPOSE:To eliminate the difference of hearing between modulating/ demodulating operation and through operation. CONSTITUTION:At the time of through operation, an input signal is filtered by not only an LPF 16 but also an HPF 24. The HPF 24 is complementary to have the low band cut-off characteristic obtained by frequency inversion of the high band cut-off characteristic of the LPF 16. The output signal of a reception-side modulating/demodulating circuit for through operation has a semicylindrical frequency characteristic, where the high band and the low band are cut, in the same manner as that for modulating/demodulating operation. As the result, an unnatural feeling of hearing at the time of modulating/ demodulating operation and at the time of through operation is disolved.
