Title: Copying machine
Inventor: HIGASHIYAMA SHUNICHI
IPC: G03F7/20
Filed: 1987-06-04
Abstract: PURPOSE:To make it possible to copy only the surface of an original distinctly even if characters, etc., are written in the rear surface of the original by arranging an optical means for diffusing and transmitting light beam in the position this side of a supporting body in an exposure means. CONSTITUTION:The light transmissible original 3 is closely arranged on a photosensitive pressure sensitive paper 4 and an irradiation light from a lamp 1 is transmitted in order of the supporting body 3a of the original 3 and the coloring part of the original 3. And a diffusion plate 6 which diffuses the light beam is arranged between the original 3 and a filter 2. The light beam emitted from the lamp 1 becomes only light of a prescribed color by passing a color separation filter 2 and radiated to the diffusion and transmission plate 6. The light beam projected to the diffusion and transmission plate 6 becomes the light beam diffused on the original side to radiate the rear surface of the color original. Even if the coloring part which shades the light beam exists on the rear surface of the original, the light beam reaches the surface of the original by by-passing the coloring part owing to the light diffusion by the diffusion plate 6. Thus, only surface of the original can be distinctly copied even if the characters, etc., are written in the rear surface of the original.

Title: Call reply detection circuit for telephone exchange
Inventor: AKIYOSHI EIJI
IPC: H04M3/02
Filed: 1986-06-17
Abstract: PURPOSE:To discriminate the hook on/off state of a telephone set by generating a binary data signal inverted in synchronism with an AC current component through a waveform shaping device and allowing the data signal to be read by a controller in synchronism with a call signal AC voltage fed to the telephone set. CONSTITUTION:With a relay 6 selected to the position of an extension circuit 5, when the input impedance of a telephone set 1 is a low resistance in the hook-off state, a loop current flows through telephone lines 2, 3 by the current supply source provided to the line 5. In this case, the current flows through a photocoupler 8 and the coupler output voltage goes to a low level by the loop current. On the other hand, in the hook-on state, since no DC loop current flows, the voltage goes to a high level. Even when a call signal is stopped tentatively because of the relay 6 selected to the position of the circuit 5, microcomputer 13 fetches an output of he photocoupler 8 as it is similarly when the call signal is sent. Thus, it is judged to be on-hook when the fetched data level is '1' and to be off-hook when the level is '0'.

Abstract: PURPOSE:To eliminate the need for complicated control by using a code word length as an integer multiple of 2, using the same number of symbols at a code word where the probability of generation is high, making the number of symbols different only for a code word having a low probability and making the appearance probability of the symbol for pulse coding to 1/2. CONSTITUTION:In case of the fixed code word where the code length is 2, when the probability of generation of codes S0, S1, S2 and S3 is taken respectively as 0.4, 0.3, 0.2 and 0.1, the code word symbol is formed as 01, 10, 00 and 11. The probability of generation of symbols 0, 1 is respectively 0.55 and 0.45 under the probability of generation of the code S1, and the probability is a value sufficiently close to 1/2. In case of 2 or 4-bit variable length code word, the code word is assigned to the probability of generation of the code S1 to bring the probability of generation of the transmitted symbol close to 1/2. The addition of a pseudo random signal and the switching control of the code word in response to the frequency of appearance of 0, 1 beforehand are not required by bringing the probability to 1/2 in such a way.
