Title: Digital-to-analaog converter
Inventor: ARAKI TETSUAKI
IPC: H03M1/00
Filed: 1984-12-31
Abstract: PURPOSE:To prevent the generation of a noise or a distortion based on a difference of a D/A conversion error by bringing a digital dither adding information signal and a digital dither signal to time division multiplexing, and converting them to an analog signal, respectively by a common digital-to-analog converter. CONSTITUTION:When a digital information signal which has converted an audio signal to PCM is inputted to an input terminal 11 of a D/A converter, a digitized dither adding information signal and a digitized dither signal are obtainer in a time division state in an output stage of adding circuit 16, and they are converted to analog signals by the same D/A converter 17. Therefore, a difference if not generated substantially between a D/A conversion error of the dither adding information signal and a D/A conversion error of the dither signal. One input and the other input of a subtracting circuit 22 are obtained based on the same D/A converter 17, therefore, a difference is not generated substantially between a D/A conversion error contained in one input and a D/A conversion error contained in the other input. Accordingly, the generation of a noise or a distortion caused by a difference of the D/A conversion error is reduced remarkably.

Title: Optical waveguide body
Inventor: ISHIKAWA YUJIRO
IPC: G02B6/02
Filed: 1989-10-26
Abstract: PURPOSE:To obtain the optical waveguide body which does not generate crosstalks when used for an optical printer and obviates the sticking of the toner on a photosensitive drum to a light exit port by forming the waveguide body in such a manner that the difference in the refractive index between a core layer and a clad layer is smaller on the light exit port side than on a light incident port side. CONSTITUTION:A photomask 3 is installed on a base film 1 formed like a sheet. The photomask 2 is alternately provided with complete light shielding parts 2b and light transparent parts 2a and is so constituted that the light transmittance of the light transparent parts 2a decreases continuously from the light exit port 3 side toward the light exit port 4 side. Namely, the photomask is so formed that the difference in the refractive index between the core layer and the clad layer is smaller on the light exit port side than on the light incident port side and, therefore, the numerical aperture on the light exit port side decreases and the light is stopped down and is emitted. The generation of the crosstalks is obviated when this photomask is used for the optical printer. Since the wider space is provided between the light exit port and the photosensitive drum, the sticking of the toner on the photosensitive body to the light exit port is obviated.
