As a result, also the change of the resonant frequency of the strip line resonator formed in the inside layer of the multilayer substrate is small, as a result, also the change of oscillation frequency becomes small. Then, since the change of the oscillation frequency is small, control voltage sensitivity can be reduced, and thus, C/N characteristics is improved. Then, since also the property of the polytetrafluoroethylene material itself is small in dielectric loss comparing with the glass epoxy and also specific dielectricity is small, the Q of resonant system is improved, and thereby, the C/N characteristics is improved too.

Title: Thermally recordable material
Inventor: KAWAI HAJIME
IPC: B41M5/337
Filed: 1990-11-27
Abstract: PURPOSE:To obtain a thermally recordable material which is free from a background fog, develops a color in black and preserves an image in extremely good condition by adding a specific phthalide chemical compound to a thermal layer containing a specific fluoran as a coloring agent. CONSTITUTION:This thermally recordable material, using colorless or pale leuco dye as a coloring agent, is thermally allowed to come into contact with a developer to develop a color. A phthalide expressed by formula 1 is added to a thermal layer containing a fluoran expressed by formula 1 as a coloring agent. The phthalide of formula 2 does not develop a color, if coming into contact with the developer, but said chemical compound becomes colored thermally in the presence of the developer. Therefore, a background fog which tends to occur, if two different types of coloring agent are mixed, does not result. When adding the chemical compound expressed by formula 2 to the thermal layer, each component is crushed and mixed, then the mixture can be applied to an area under or on the thermal layer as another step. In addition, the addition amount is not necessarily limited particularly and can be selected appropriately within a range of 5 to 100% against the chemical compound of formula 1.
