Title: Surface acoustic wave filter
Inventor: TANJI SHIGEO
IPC: H03H3/08
Filed: 1981-12-22
Abstract: PURPOSE:To prevent a bulk wave from being affected on a pass frequency band of a filter, by selecting the thickness of a substrate from a frequency constant of a thickness longitudinal oscillation specific to a piezoelectric crystal in use. CONSTITUTION:The relation of A/d fr exits among a frequency constant A of the thickness longitudinal oscillation of a piezoelectric crystal substrate, the primary resonance frequency (fr), and the thickness (d) of the substrate. Through this relation, the thickness (d) of the substrate is adjusted so that the resonance frequency (fr) of the thickness longitudinal oscillation can not affect the pass frequency band of the filter to be manufactured. For example, in designing the filter having 41-48 MHz of the pass frequency band using lithium niobate crystal substrate of 128 deg. rot. Y-cut, X propagation, when the thickness of the substrate is denoted as 300mum, the primary mode of the thickness longitudinal oscillation is around 11.5MHz, the ternary mode is 34.6MHz and the quinary mode is 57.6Mhz. They are not within the pass frequency band of the filter, allowing to prevent the effect of bulk waves.

Title: Multicolor heat sensitive recording medium
Inventor: OKIMOTO SATOYUKI
IPC: B41M5/34
Filed: 1988-08-23
Abstract: PURPOSE:To provide a multicolor heat sensitive recording medium having excellent head matching characteristic by incorporating polyvinyl alcohol including specific saponification degree and viscosity in all layers on a support. CONSTITUTION:This multicolor heat sensitive recording medium has at least a high temperature coloring layer, a color fading layer, a low temperature coloring layer, and further includes an intermediate layer between the coloring layer and the color fading layer to be laminated with four or more layers. It is necessary for improvement of head matching properties to contain 95mol% or more of polyvinyl alcohol of saponification degree (JIS K-6726-1965) in the layers. However, if the viscosity of the alcohol is low, the adherence of head chips in case of recording cannot be sufficiently improved, while if the viscosity is excessively high, it tends to become irregular in case of coating the support with a coating solution. Accordingly, the polyvinyl alcohol having specific saponification degree of 7-45cps and more desirably 15-35cps of viscosity (measured by a B type viscometer at 20 deg. with 4% aqueous solution) is employed for all the layers.
