    • A mold monitoring apparatus for an injection molding machine captures an image of a cavity portion of an opened mold, and determines the state of the cavity portion by means of image processing. The apparatus includes a light emitting unit, an image capturing unit, and an image processing unit. The light emitting unit projects onto the cavity portion light rays other than visible light rays. The image capturing unit includes an image sensor for capturing reflection light rays that travel from the cavity portion to the image sensor via a filter for blocking visible light rays. The image processing unit determines the state of the cavity portion on the basis of an image signal output from the image sensor and through image processing.
    • 用于注射成型机的模具监控装置捕获打开的模具的空腔部分的图像,并且通过图像处理确定空腔部分的状态。 该装置包括发光单元,图像捕获单元和图像处理单元。 发光单元突出到可见光线以外的空腔部分的光线。 图像拍摄单元包括图像传感器,用于捕获通过用于阻挡可见光线的滤光器从空腔部分传播到图像传感器的反射光线。 图像处理单元基于从图像传感器输出的图像信号和图像处理来确定空腔部分的状态。

    • The purpose of the present invention is to provide a nozzle for resins having a highly temperature-dependent viscosity by dividing the nozzle into a nozzle tip and a nozzle main body, and limiting a passage of a tapered hole formed in the nozzle main body, a gradient of a nozzle port, a passage volume, or the like within specific ranges. The passage 13 in the nozzle main body 1 is formed of a tapered hole with a gentle gradient without a step. The nozzle tip is made of low thermal conductivity metal. The nozzle port at the center of the nozzle tip is formed of a tapered hole. The internal side diameter and the diameter of the front end hole 13a of the passage 13 are set within the range of 0.9-1.5 mm capable of preventing a dropping phenomenon without causing a large pressure loss. The passage volume is limited to 1.0 cm3 or less within the range of 70-115 mm in length of the nozzle main body 1.
    • 本发明的目的是提供一种通过将喷嘴分成喷嘴头和喷嘴主体而具有高温度依赖性粘度的树脂喷嘴,并且限制形成在喷嘴主体中的锥形孔的通道, 在特定范围内的喷嘴口的梯度,通道体积等。 喷嘴主体1中的通道13由没有台阶的温和梯度的锥形孔形成。 喷嘴尖由低导热性金属制成。 喷嘴尖端中心的喷嘴口由锥孔形成。 通道13的前端孔13a的内侧直径和直径设定在0.9-1.5mm的范围内,能够防止掉落现象,而不会造成大的压力损失。 通道体积在喷嘴主体1的长度为70-115mm的范围内被限制为1.0cm 3以下。

    • There is disclosed a data transmission system comprising a first and a second loop transmission line for transferring data in its clockwise and counterclockwise directions, respectively. In each loop transmission line a plurality of transmission control units are connected in series. Further, a plurality of terminal units each are interconnected with its associated first and second transmission control units correspondingly and respectively located in the first and second loop transmission lines. Each of the transmission control units in the first loop transmission line is interconnected to a corresponding one of the transmission control units in the second loop transmission line by a bypass line so as to make a pair, so that a fault in the loop transmission line may be detected and a loop transmission line bypassing the fault point may be established without using any master transmission control unit.
