    • The termite detecting device is placed in an expected invading passage for detecting damage or destruction caused by termites. One configuration of the device includes: a detecting wood sample for attracting termites; a detecting terminal being pressed against the detecting wood sample while the detecting wood sample is supplied with water as required; and a magnetic circuit capable of being opened and closed by the movement of the detecting terminal. When the detecting wood sample is eaten and damaged by termites and becomes fragile, the detecting terminal sinks into the detecting wood sample by virtue of a pressing force and the magnetic circuit is made open. As a result, the device detects the existence of termites. Alternatively, another configuration of the termite detecting device detects vibrations caused by termites so as to detect the invasion of termites. In either device, when a valid signal from a magnetic sensor or a vibration sensor is issued, an indicator disposed in a house is activated to warn in response to the sensor signal. Alternatively the valid signal is transmitted by way of telephone line, etc., to a control center. Thus, the device warns the user of the invasion by termites in an early stage so that the user may take a quick action.
    • 白蚁检测装置放置在预期的入侵通道中,用于检测白蚁造成的损坏或破坏。 该装置的一种结构包括:用于吸引白蚁的检测木材样品; 检测端子被按压在检测木材样品上,同时根据需要向检测木材样品供水; 以及能够通过检测端子的移动来打开和关闭的磁路。 当检测木材样品被白蚁食用并损坏并变脆时,检测终端借助于压力将其吸入检测木材样品中,并使磁路打开。 因此,该装置检测白蚁的存在。 或者,白蚁检测装置的另一配置检测由白蚁引起的振动,以便检测白蚁的入侵。 在任一装置中,当发出来自磁传感器或振动传感器的有效信号时,设置在房屋中的指示器被激活以响应于传感器信号而发出警告。 或者,有效信号通过电话线路等传输到控制中心。 因此,该设备在早期阶段向用户警告白蚁入侵,以便用户可以快速采取行动。

    • In an image processing apparatus, images on an original document captured by an image capturing device are classified into a binary image and a gradation image, and the densities of the images are then converted using density conversion curves, which are provided for binary images and gradation images, to output an image signal representing converted images. The state of a certain pixel is judged and is classified as one of a plurality of states between binary images and gradation images. Based on the results of the judgment, one curve is selected from a first density conversion curve for binary images, a second density conversion curve for gradation images and at least one third density conversion curve which interpolates the first and second density conversion curves. The density of the certain pixel is converted using the selected curve. The image processing apparatus can provide a high contrast in a binary image area of an original document and maintain the gradation of an image in a gradation image area of the original document. Also, the apparatus can output an image density signal which does not cause an unnatural vision due to an abrupt change in density.
    • 在图像处理装置中,将由图像拍摄装置拍摄的原稿上的图像分类为二值图像和灰度图像,然后使用密度转换曲线将图像的浓度转换为二值图像和灰度 图像,以输出表示转换图像的图像信号。 判断某像素的状态,并将其分类为二进制图像和灰度图像之间的多个状态之一。 基于判断结果,从二值图像的第一密度转换曲线,灰度图像的第二浓度转换曲线和内插第一和第二浓度转换曲线的至少一个第三密度转换曲线中选择一个曲线。 使用所选曲线转换特定像素的密度。 图像处理装置可以在原始文档的二进制图像区域中提供高对比度并且在原始文档的灰度图像区域中保持图像的灰度。 此外,该装置可以输出由于密度突然变化而不引起不自然的视觉的图像浓度信号。

    • In an automatic analyzer of samples, the liquid specimen and the reagent are mixed in a reaction container to react. If, however, there is a bubble in the reagent container, a accurate amount of a reagent may not be dispensed. Accordingly, a liquid surface detecting circuit for detecting the liquid surface on the basis of the impedance change between a pipet and a ground is disposed, and the height of the liquid surface before and after suction of the reagent is compared on the basis of the liquid surface detecting information, and the bubble is detected when the difference is more than a specified value, and accordingly the driving circuit of the driving source is controlled by the control circuit. Thus, when dispensing the reagent in the reagent container by a pipet, the bubble can be detected securely and accurately, and this apparatus may be used in a slender reagent container.
