Abstract: PROBLEM TO BE SOLVED: To attain stable transmission by forming at least optical frequencies of plural optical signals with combinations of three optical frequencies or over and differentiating a difference of all of two optical frequencies over a 1st separation or over so as to avoid the effect of FWM crosstalk. SOLUTION: All signal lights f1 -fn are arranged to any slot set at an interval of ΔfS- F. In this case, an FWM light is in existence in any slot. When an interval between optical frequencies f1 and fi+1 (i=1-n-1) is selected to be a multiple of mi of the slot Δfi+1 , a separation of the ΔfS- F is secured between the FWM light and the signal light by deciding m1 ,...mn-1 so that the m1 , m2 ,...mn-1 and consecutive (i-2) sets of sums m1 +m2 ,m +m3 ,..., m2 +m3 +...mi-1 are all different. Furthermore, the required band width is minimized by minimizing the sum of all m1 , that is, m1 +m2 +,...+mn-1 .

Filed: 1980-04-18
Abstract: PURPOSE:To transfer electric charges by snaking a high-concentration channel stopper whose conductivity type is the same as a substrate along one of gate electrodes of upper or lower layers  which are arranged crisscross on the substrate, and providing a light receiving part without using  transparent electrode. CONSTITUTION:When light receiving parts (b) are illuminated from the side of electrodes 11...  and 12... electrode are generated at the light receiving parts (b) in response to the amount of  incident light. When counting pulse phi1 is kept at a high voltage and phi2 is kept at a low voltage, the  electrons are concentrated under the lower electrodes 11... to which the pulse phi1 is applied. When  the voltage is changed, the electrons move to the position (c) at the lower electrodes 11 whose  voltage is high along the side wall of the channel stopper 8 through the position (b) at the upper  electrodes 12 whose voltage is high. In this way, the electrons are transferred along each channel  9 by phi1 and phi2, and taken out to the outside at the terminal ends as image information. Insulated  upper and lower gate electrodes which are crossed to each other are provided. Since the channel  stopper is snaked along one electrode to obtain the snaking channel, the integrating density is high,  and the transfer efficiency can be improved. Since the part wherein an electrode is not provided  is made to be the light receiving part, the pickup elements which are not based on the hue of the  incident light can be obtained.

IPC: H04N5/232
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To omit a level fixing wiring pattern by making a terminal level capable of being fixed in the inside of an IC. SOLUTION: This signal processing IC circuit is provided with built-in level fixing means 35a to 35h to fix the terminal level of data transmission lines L, L' between an external terminal 30 and an interface part 22.
