Title: Non-radioactive dielectric line
Inventor: SAITO ATSUSHI
IPC: H05K9/00
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To thicken a non-propagation area dielectric layer and to attain the integral molding of respective components by shortening an inter-conductor distance in a non-propagation area as compared with that in a propagation area and forming a dielectric layer with a low dielectric constant in the non-propagation area. SOLUTION: A distance h1 between dielectric substances 1, 2 in the propagation area is set up longer than a distance h2 between dielectric substances in the non-propagation area. A non-propagation area dielectric part is constituted of a dielectric layer 5 having a dielectric constant ε2 lower than the dielectric constant ε1 of a dielectric layer 3' continued from a propagation area dielectric substance 3. When the dielectric constants ε1, ε2 and the distances h1, h2 are set up, electromagnetic waves in a prescribed frequency band can be transmitted in the propagation area and cut off in the non-propagation area. The thickness (t) of the layer 3' can be thickened as compared with a size that the distances h1, h2 are equal.  Even when the whole side of the dielectric line is miniaturized by the use of a dielectric material having a high dielectric constant, the thichness(t) is not remarkably reduced, the whole elements can be thichness molded by injection molding or the like, and since the propagation area and the non-propagation area can be simultaneously constituted, the positioning/fixing of a dielectric strip, the problem of mass production and characteristic variation can be solved.

Filed: 1981-12-28
Abstract: PURPOSE:To average a load of an asynchronous bus, and to easily design a system, by transferring the data of a channel on the asynchronous bus in conformity with integer times a transfer period of an input/output device. CONSTITUTION:A value which is equal to integer times a data transfer period of I/O, or is similar to said contents is preset to a counter 2, and after waiting for the time when the counter 2 overflows, DMA (direct memory access) request sequence is started. In the beginning of the DMA sequence, the counter 2 is  preset, and driving of the counter 2 is started. Also, in case when the counter 2  does not overflow when the DMA sequence has ended, even if the following  DMA sequence is requested, it is made to wait until the counter 2 overflows.  On the other hand, in case when the counter 2 overflows when the DMA sequence has ended, the following DMA sequence is started immediately. By this  operation, the DMA transfer period of the channel becomes nearly integer times  the data transfer period of I/O.
