Title: Light wavelength multiple branching system
Inventor: HASHIMOTO KUNIO
IPC: H04B10/29
Filed: 1978-08-11
Abstract: PURPOSE:To obtain the light wavelength branching filter of low coupling losses and less deviations for respective wavelength bands by subsequently arraying the band- pass filters using interference films from the wavelength bands of larger optical fiber transmission losses. CONSTITUTION:In the transmission path, the wavelength at which the optical path length in glass bulk 10 for the wavelength giving maximum loss is first taken out, whereby the reduction in losses is accomplished. The losses of the respective wavelengths become smaller in the order of lambda1, lambda8, lambda4, lambda2, lambda3, lambda7, lambda5, lambda6. For this purpose, interference film band-pass filters are arrayed in the order of 21, 28, 24, 22, 23, 27, 25 so that the optical path lengths in the bulk become subsequently longer. As a result of such constitution, the loss fluctuations of transmission systems by the transmission line and multiple branching circuit may be reduced.

Abstract: PURPOSE:To uniformize pressure and to obtain a forming part of uniform nature by switching the control of a hydraulic cylinder to a pressure control from a speed control at the time when the hydraulic cylinder is moved by the amt. corresponding to a deviation value from the specified stroke position. CONSTITUTION:The die inner pressure P0 at the point S4 of the front of a speed-pressure switch is preset and the difference  S in the inner pressure P of the point S4 and S5 switching from a speed control to pressure control is found in advance by an experiment, etc. The deviation value  P of P0 and P and  S at that time are then stored in a control device 28. In case of a material being overfilled, P1>P0 is attained by detecting the die inner pressure P1 at the point S4 of the front of the speed-pressure switching, P'=P0-P1 is found, the  S' corresponding to this  P' is found and switching is executed from speed control to pressure control at the position where a slide stroke becomes S5=S4+S'. The dispersion in the material filling state is thus detected by the die inner pressure and the filling completion time is corrected, so the switch of the speed-pressure control becomes at the material filled up time and the succeeding forming is uniformized.

Abstract: PROBLEM TO BE SOLVED: To reduce a communication cost by integrating transfer data being the telephone number of the transferring destination of picture data with picture data so as to transmit transferring data by fast communication. SOLUTION: The inputted telephone number of a transmission destination is temporarily stored in RAM. Then based on the inputted telephone number of the transmission destination, transferring data is prepared. Next a picture reading part reads a picture original to prepare binary and two-dimensional data based on gradation information of the original. Next transferring data is added to the top of read picture data to compose. At this time transferring data 21 is stored in a transferring data area 22 so that one transferring data may be equivalent to the one line part of picture data. Consequently this picture data 24 is added with one line part of transferring data 25 at the top row. Next, composed data is compressed by a two-dimensional encoding system. Then data transmission is started by a prescribed transmission control procedure.
