    • A matrix relay is formed with a plurality of latching relays arranged in a matrix and mounted on a base of an electrically insulative material. Each of the latching relays comprises an excitation coil, permanent magnet, a pair of first and second fixed contacts, and an armature carrying a pair of first and second movable springs each providing movable contacts. The armature is magnetically coupled to the excitation coil so as to be movable in response to energization of the coil by current of selective polarity between close and open positions of the fixed and movable contacts. A plurality of the armatures of the latching relays arranged in a row of the matrix are assembled into a single armature block to be mounted on the base as a single unit. The armature block comprises a single pair of first and second supporting members made of an electrically conductive material. All of the first movable springs and all of the second movable springs of the latching relays of the armature block are connected respectively to the first and second supporting members mechanically and electrically, so that two row paths for electrical signals common to the latching relays arranged in the row of the matrix are provided. This simplification of the structure and electric circuit of the matrix relay would be useful to small-size the matrix relay without complicated fabrication process.
    • 矩阵继电器形成有多个以矩阵形式布置并且安装在电绝缘材料的基座上的闭锁继电器。 每个闩锁继电器包括励磁线圈,永久磁铁,一对第一和第二固定触点,以及承载一对第一和第二可移动弹簧的衔铁,每个可移动弹簧提供可动触点。 电枢被磁耦合到励磁线圈,以便响应于线圈通过固定触点和可动触头的接近和断开位置之间的选择性极性的电流而可移动。 安排成一排矩阵的闭锁继电器的多个电枢被组装成单个电枢块,以作为单个单元安装在基座上。 衔铁块包括由导电材料制成的单对第一和第二支撑构件。 电枢块的闭锁继电器的所有第一可移动弹簧和所有第二可移动弹簧机械和电气分别连接到第一和第二支撑构件,使得用于锁定继电器共同的电信号的两个行路径布置在 提供矩阵的行。 矩阵继电器的结构和电路的这种简化对于小型矩阵继电器而言是有用的,而不需要复杂的制造工艺。

    • An image forming apparatus including a fixing roller and a pressure roller in which a temperature of the fixing roller and/or the pressure roller is changed differently depending on an operation mode. In particular, the temperature of the fixing roller and/or pressure roller of an operation of a non-full color mode is changed to a lesser degree than that of a full color mode operation. In another embodiment of the present invention, the temperature of the fixing roller is set to an appropriate value when an environment temperature sensor is not working properly, to produce high quality images. In yet another embodiment according to the present invention, the temperature of the fixing roller is set to an appropriate value, when an image forming apparatus is turned off for a predetermined period of time, to produce high quality images.

    • An image forming apparatus of the type producing a single composite color image on a paper which is transported by a belt by transferring image components of different colors to the paper in register with each other. The apparatus reduces with a simple construction the positional deviation of the image components which occurs in an intended direction of paper transport. Recording devices individually adapted for black, cyan, magenta and yellow are arranged side by side. Pattern images for measurement each being associated with a respective one of those colors are formed on the belt. A timing at which each of the pattern images arrives is sensed and counted. The count is compared with a reference value to calculate an amount of deviation. Write start timing signals each being associated with a particular color are generated which are individually variable on the basis of the deviation calculated. The pattern images of the respective colors are each generated by using a write start timing associated with the color as a reference, and the pattern to be provided by any of the recording devices is outputted on a downstream side of the belt relative to the pattern to be provided by another recording device which is located downstream of the first-mentioned recording device.
    • 一种在纸张上产生单一复合彩色图像的图像形成装置,其通过将不同颜色的图像分量传送到纸张而被传送的纸张彼此对准。 该装置以简单的结构减少了在纸张传送的预期方向上发生的图像分量的位置偏差。 分别适用于黑色,青色,品红色和黄色的记录装置并排布置。 在带上形成有与这些颜色中的相应颜色相关联的用于测量的图案图像。 每个图案图像到达的定时被感测和计数。 将计数与参考值进行比较以计算偏差量。 生成与特定颜色相关联的写入开始定时信号,其基于计算的偏差而单独变化。 各颜色的图案图像各自通过使用与颜色相关联的写入开始定时作为基准来生成,并且由任何记录装置提供的图案相对于图案在带的下游侧输出到 由位于第一记录装置下游的另一记录装置提供。
