Title: Optical branching coupling device
Inventor: NAKAMURA TAKESHI
IPC: G02B6/28
Filed: 1986-11-14
Abstract: PURPOSE:To easily prevent a variance from being generated in the optical output of a signal line which has been brought to branching, by fusing the side faces of two pieces of optical fibers from which a clad has been eliminated, so that the cross-sectional area is not varied, and fusing the cross section of the fused part and the end face of other optical fiber. CONSTITUTION:As for optical fibers 101, 102, a clad in the vicinity of the tip is eliminated, the side face is heated and fused 114, and a core exposed part is covered with a transparent Si resin 130 whose refractive index is smaller than the clad of the optical fiber. Cores 111, 112 are brought into contact with each other in the cross section of II-II but not fused, deformed gradually and fused, become a circular cross section shape, and heated and fused 140 to the cross section of an optical fiber 103. In this state, a signal light which has been propagated through the fiber 103 is allowed to branch to the fibers 101, 102 in an equal ratio to each other, respectively, since the cross-sectional areas of the cores 111, 112 are equal in a fused part 114. Also, since the variation of a propagation mode is suppressed by the fused part 114, there is no signal light which is made incident on clads 121, 122 of the fibers 101, 102, therefore, the loss becomes low.

Title: Image coder, image encoder, and coding decoding system
Inventor: ASAI KOTARO
IPC: H04N19/51
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To reduce number of samples of color difference components, to decrease color noise, and to improve the coding efficiency by detecting a state change of image data and selecting a format. SOLUTION: An input image signal is converted into a digital signal by an A/D converter 1 and the format is converted. The image data are converted into image data of other 4:2:0 format by using a local format 2. Since the sample density of the color difference component of this format is low, the total sample number to be coded is reduced and the compression efficiency is enhanced. Then an image state discrimination section 3 selects an output 102 of the local format 2 or original image data 101 and a DCT 4 is used to convert the selected data into a conversion coefficient 104 of a spatial frequency region. Moreover, a quantization section 5 quantizes the coefficient to convert the DCT coefficient into linear information 105 and it is variable-length-coded by a variable length coder 6. The coded data are stored in a buffer 7, from which a coded bit stream is outputted.  Thus, color noise is reduced and the coding efficiency is increased.
