Title: Analysis method for propagation problem circuit using spatial network method
Inventor: TAKAHASHI HIDEOMI
IPC: G06F17/13
Filed: 1994-03-31
Abstract: PURPOSE:To avoid the number of pieces limit for mutual inductance and the use of a gyrator, and apply a general-purpose circuit analysis tool by combining two basic Maxwell equations for deriving a propagation equation, and using the propagation equation for constituting a spatial network. CONSTITUTION:Current flowing across building steel frame sections P and Q is thunderbolt current (i) plus two types of current ic1 and ic2 entering the sections P and Q after propagation through a spatial network. Normally, the current cannot be separated, but spatial surge impedance Z0 is considerably larger than the surge impedance Z1 of the sections P and Q. Thus, the current (i) and a sum of Ici and ic2 due to induced voltage, flow to the surge impedance z1 between the sections P and Q. On the other hand, two types of current ic1 and ic2 flow across spatial section Z0 and, therefore, the thunderbolt current (i) flowing across the sections P and Q can be obtained by deducting the current icl and ic2.

Title: Core for winding plastic film
Inventor: OOTA TSUYOSHI
IPC: B65H75/18
Filed: 1986-03-25
Abstract: PURPOSE:To make transcription from a core to a film and copying by dust restrainable, by forming a core surface into such one that maximum roughness Rt is less than the specified value and has regular unevenness whose center line mean roughness Ra is within the specified range. CONSTITUTION:A core surface is formed into such one that maximum roughness Rt is less than 10mu and has regular unevenness whose center line mean roughness Ra is within the range of 0.2-2mu. Here, when Rt>10mu or Ra>2mu is the case, it is undesirable because the unevenness itself on the core surface is transferred, and when Ra<0.2mu is the case, there is not transcription from the core itself but dust sticking to the core surface is protruded out of the flat core surface, whereby copying from the dust happens there. At the range of Rt<=10mu and 0.2mu<Ra<=2mu, the transcription from the core surface is almost nothing, if any, it is as negligible as small, so there is no problem on this matter, and that even if minute dust sticks to the core surface, it has been buried in concavities of the regular unevenness, so that if pressing force is imposed on from the film side, copying from the dust is prevented from occurring.
