Filed: 1989-11-09
Abstract: PURPOSE:To obtain a hybrid printed circuit board by a method wherein electric resistors which contain organic powder are printed on an organic board of paper phenol or the like, which is burned and formed into a sheet separable into individual pieces and transferred onto a previously prepared structure like a printed wiring board. CONSTITUTION:For instance, carbon resistors 3 are printed on an organic temporary board 1 and baked, and electrodes 2 are also baked at the same time. V-shaped cutting grooves 6 are provided to the board 1 by processing, and the board 1 is divided into usable pieces 4 and disused pieces 5. Electrodes 12 of a copper clad actual board 11 are pressed against electrodes 2 of the usable pieces 4 of the temporary board 11 and joined together with solder paste of Sn-Pb eutectic. If the boards 1 and 2 are coincident with each other in linear expansion coefficient at a temperature of -55-150 deg.C, they are easily connected together with a conductive adhesive agent through a dry curing connection method. By this constitution, hybrid circuits can be collectively mounted on an economic board, so that a hybrid printed circuit board can be saved in manufacturing time and cost.

Title: Manufacture of junction optical fiber coupler, junction optical fiber coupler, and optical fiber coupler manufacturing device
Inventor: SUGITA AKIHIKO
IPC: G02B6/287
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To improve the productivity by saving the time of fusion adhering and to make the optical loss nearly uniform by slackening the intersection parts of other fibers (POF) so that the length of the intersection part of other POFs is nearly equal to the length of the intersection parts of some POFs and welding branch points at a time for the branch parts of plural stages. SOLUTION: Even 1st and 4th POFs (1) and (4) which do not cross each other have excessive parts M1 and M2 formed to give excessive length nearly equal to that of 2nd and 3rd POFs (2) and (3) which cross each other and thus the respective POFs (1) to (4) do not have differences in length. Consequently, differences in optical loss and phase shifts of light between the respective POFs (1) to (4) are prevented. This POF coupler is reduced in procedures and frequency by fusing and adhering branch join points P1a, P1b, P2a, and P2b at a time by the stages (P1, P2) through mechanical automation.

Abstract: PURPOSE:To display the inverting signal of a color burst signal in blue as the background signal of the video by generating a signal having the inverting phase from the color burst signal and removing the voltage of a voltage generating circuit to generate the prescribed voltage through the switch switched by an inverting phase signal. CONSTITUTION:A timing control circuit 13 and a horizontal/vertical synchronizing signal generating circuit 14 to send the action signal to analog switches A1-A6 are provided, and the color burst signal from a color burst oscillator 11 is inputted. The timing control circuit 13, based upon the color burst signal, sends the inverting timing to a color burst to switches A2 and A6 and sends the non-inverting timing signal of the color burst to switches A4 and A5. Since the phase inverting signal of the color burst signal is equivalent to blue, the inverting wave of the color burst signal is mounted as the carrier chrominance signal during the background signal period. Consequently, when the video signal is generated to the whole scanning line, the blue background can be formed on the television screen.
