    • Thermal transfer recording is improved by a recording method involving providing a thermal transfer material having a support and an ink layer disposed thereon and which in turn includes a binder and a colorant. The binder includes 45-70 wt. % of an ethylene-vinyl acetate copolymer, 25-50 wt. % of a wax, and 7-12 wt. % of a tackifier based on a total weight of the binder. The ink layer has a breakdown strength of 30-80 kg/cm.sup.2 at 25.degree. C. The method also involves contacting an ink layer side of the thermal transfer material with a recording medium, supplying a pattern of energy from a recording head to the thermal transfer material, and separating the thermal transfer material from the recording medium to leave a transferred image on the recording medium. The thermal transfer material moves in a unit period of time by a first distance relative to the recording head which is smaller than a second distance through which the recording medium moves relative to the recording head in the same unit period of time.
    • 通过提供具有支撑体的热转印材料和设置在其上的油墨层并且还包括粘合剂和着色剂的热转印材料的记录方法来改进热转印记录。 粘合剂包括45-70wt。 %的乙烯 - 乙酸乙烯酯共聚物,25-50wt。 %的蜡,和7-12wt。 基于粘合剂的总重量的增粘剂的%。 油墨层在25℃下的击穿强度为30-80kg / cm2。该方法还包括使热转印材料的油墨层与记录介质接触,将记录头的能量图案提供给热 转印材料,并将热转印材料与记录介质分离,以将转印图像留在记录介质上。 热转印材料在单位时间内相对于记录头移动第一距离,该距离小于记录介质在相同的单位时间内相对于记录头移动的第二距离。

    • A tape like material including synthetic resin for a filter element is bent into a corrugated pattern while the material is passed between pairs of forming and cutting rollers. Since pairs of cutters are provided within the rollers and since guide plates are provided around the rollers, the material is held abutting the rollers even when the material is cut by the cutters. The material is then conveyed within a reducing drum. The pitch of the corrugated portions formed on the material is reduced and the material is formed into a semicircular shape within the reducing drum. After passed the reducing drum, the material is transferred to a forming path. Since the forming path has an introducing portion having a semicircular sectional shape similar to that of the material leaving the reducing drum, an outlet portion having a circular sectional shape similar to that of the finished filter element and an intermediate portion having a sectional shape gradually varied from the shape of the introducing portion to the shape of the outlet portion, the material is shaped to a complete circle while the material travels along the forming path. A crystal type filter element is thus formed from a tape like material automatically.
    • 包括用于过滤器元件的合成树脂的带状材料在材料在成形辊和切割辊之间通过时被弯曲成波纹状图案。 由于成对的切割器设置在辊内,并且由于在辊周围设置导向板,所以即使当切割器材料被切割时,材料也保持抵靠辊。 然后将材料在还原鼓内输送。 形成在材料上的波纹部分的间距减小,并且材料在还原滚筒内形成半圆形。 在通过还原鼓之后,将材料转移到成形路径上。 由于形成路径具有与离开还原鼓的材料类似的半圆形截面形状的引入部分,具有与完成的过滤元件类似的圆形截面形状的出口部分和具有逐渐变化的截面形状的中间部分 从引入部分的形状到出口部分的形状,材料成形为完整的圆形,同时材料沿着成形路径行进。 因此,由带状材料自动形成晶体型滤光元件。
