    • There is provided a production method for a liquid discharging apparatus including a liquid discharging head having a discharging port configured to discharge liquid, and a thermoplastic support portion having a liquid supply passage configured to supply the liquid to the liquid discharging head. The production method includes a preparation step of preparing the liquid discharging head and the support portion, a heating step of heating the liquid discharging head, an approach step of moving the liquid discharging head close to the support portion and melting the support portion by applying radiant heat from the liquid discharging head to the support portion, and a pressing step of pressing the liquid discharging head against the support portion so that the melted support portion forms a wall portion to contact an outer peripheral portion of the liquid discharging head.
    • 提供了一种液体排放装置的制造方法,该液体排出装置包括具有排出液体的排出口的液体排出头,以及具有将液体供给到液体排出头的液体供应通道的热塑性支撑部。 该制造方法包括:准备液体排出头和支撑部的准备工序,加热液体排出头的加热步骤,将液体排出头靠近支撑部分移动并通过施加辐射来熔化支撑部分的接近步骤 从液体排出头到支撑部分的热量,以及将液体排放头压靠在支撑部分上的压制步骤,使得熔化的支撑部分形成与喷液头的外周部分接触的壁部分。

    • There is described a signal processing apparatus, which conducts processing of a signal outputted from an image capturing element that converts an optical image obtained by irradiating light on an object such as document to an electric signal. The apparatus includes: a sample-and-hold section to sample and hold a black signal level and an image signal level, both included in an analogue image signal inputted from an image capturing element; an analogue-to-digital converting section to convert the analogue image signal to digital image data within a predetermined number of conversion steps, which is larger than a number of conversion steps corresponding to a differential value between the black signal level and the image signal level; and a digital subtracting section to subtract black digital-image data representing the black signal level from signal digital-image data representing the image signal level, both being converted by the analogue-to-digital converting section.
    • 描述了一种信号处理装置,其对从图像拍摄元件输出的信号进行处理,该图像摄影元件将通过将诸如文档的对象照射光而获得的光学图像转换为电信号。 该装置包括:采样保持部分,用于采样和保持黑色信号电平和图像信号电平,两者都包括在从图像捕获元件输入的模拟图像信号中; 模拟数字转换部分,用于在预定数量的转换步骤中将模拟图像信号转换为数字图像数据,该转换步长大于与黑色信号电平和图像信号电平之间的差分值相对应的转换步骤的数量 ; 以及数字减法部分,用于从表示图像信号电平的信号数字图像数据中减去表示黑色信号电平的黑色数字图像数据,两者都由模数转换部分转换。
