产品课题

随着打印机、复印机、印刷机的普及，对彩色打印的需求增加，图像质量受到关注，我们一直担心定影辊划伤导致图像质量下降。

为解决课题开展的工作

解决方案是可称之为终极解决方案的非接触式。通过应用SEMITEC独创的薄膜热敏电阻的小型、高精度和高速响应特性，我们开发了一种检测辐射红外线的非接触式温度传感器（NC传感器），并已投放市场。业界首款热敏电阻型非接触式NC传感器，通过在吸收辐射红外线的基板上安装两个高精度配对的检测和补偿用薄膜热敏电阻，实现非接触式红外线检测。由于也曾是为定影单元开发的，所以除了150℃的耐热性外，还具有不易受干扰影响的结构，并且具有即使墨粉或纸粉积聚也对输出影响很小的优点，如今也可在客户的定影单元内安装传感器。NC传感器系列随着每个开发时代的发展而不断改进，近年来随着定影单元的节省空间化，正日趋向小型化的方向不断进化。这种NC传感器可以组合使用接触式和非接触式传感器，有利于客户实现各种设计。

SEMITEC‘s Ultra-compact, High-precision Sensors for Advanced Medical Applications

SEMITEC developed the Fμ series of thin-film thermistors. Both ultra-compact and highly accurate, they incorporate SEMITEC proprietary thin-film thermistor technology. This enables the production of thermistor temperature sensors with a diameter of 0.5mm or less for use in advanced medical applications such as catheters. SEMITEC also succeeded in developing the ultra-compact “Pμ sensor“ pressure sensor and three-dimensional “CF sensor“ contact force sensor.
