    • A droplet ejection device includes a droplet ejection head. The droplet ejection head includes droplet ejection nozzles, a common liquid chamber, an air vent nozzle, and a nozzle face. The ejection nozzles are arranged side by side in a vertical direction. Each ejection nozzle has a first channel to eject droplets. The vent nozzle has a second channel to vent air from the common chamber. The nozzle face is disposed in the vertical direction or a direction tilted downward relative to the vertical direction. The first channel is tilted downward so that a side proximal to the nozzle face is lower than another side proximal to the common chamber. The vent nozzle is disposed above a topmost one of the ejection nozzles. The second channel is tilted upward so that a side proximal to the nozzle face is higher than another side proximal to the common chamber.

    • An image pickup apparatus which is capable of achieving excellent moving image shooting even when strobe popup is not successfully performed during moving image shooting. A camera implementing the image pickup apparatus has a strobe that shifts between a retracted position and a service position. When a motor for operating the camera performs reverse rotation, the strobe is driven to the service position. An MPU instructs the motor to drive the strobe to the service position, and determines, based on a signal from a popup position-detecting switch, whether or not the strobe has been normally driven to the service position. When the strobe has not been normally driven to the service position, the MPU performs error handling. The error handling is carried out differently between a case where moving image shooting is being performed and a case where the moving image shooting is not being performed.
    • 即使在运动图像拍摄期间没有成功执行闪光灯弹出时,也能够实现优异的运动图像拍摄的图像拾取装置。 实现图像拾取装置的相机具有在缩回位​​置和服务位置之间移动的闪光灯。 当用于操作照相机的电动机进行反向旋转时,闪光灯被驱动到维修位置。 MPU指示电动机将频闪驱动到服务位置,并且基于来自弹出位置检测开关的信号确定频闪是否被正常地驱动到服务位置。 当频闪没有被正常地驱动到服务位置时,MPU执行错误处理。 在执行运动图像拍摄的情况与未执行运动图像拍摄的情况之间进行错误处理。

    • A numerical controller in which group IDs are automatically allocated to I/O units so that the group IDs and addresses can be set automatically even when a system configuration is changed in response to detection of a configuration error. When a power of the numerical controller is turned on, group IDs are successively allocated to I/O units with distance from the numerical controller, and types of the I/O units are stored. Initial values of the group IDs allocated when the power is turned on for the first time after a system of the numerical controller is constructed, and addresses for the allocated group IDs are stored. An alarm is issued if the types and number of units for the group IDs automatically allocated for the second or later time of starting the numerical controller are different from the initial values.
    • 一种数字控制器,其中组ID被自动分配给I / O单元,使得即使当响应于配置错误的检测而改变系统配置时,也可以自动设置组ID和地址。 当数字控制器的电源打开时,组ID被依次分配给与数字控制器的距离的I / O单元,并存储I / O单元的类型。 在构建数字控制器的系统之后第一次接通电源时分配的组ID的初始值以及所分配的组ID的地址被存储。 如果自动分配用于启动数字控制器的第二个或更晚的时间的组ID的类型和数量与初始值不同,则发出报警。

    • A head controller controls pressure creating means for contracting and expanding the volume of a pressurizing compartment communicating with a nozzle of a droplet discharging head. Drive waveform generating means outputs a drive pulse including a first waveform element expanding the compartment, a second waveform element maintaining the expanded state of the compartment, and a third waveform element contracting the compartment so that droplets are discharged. When a first potential difference is a potential difference between the first waveform element at the beginning of the expansion and the second waveform element, and the second potential difference is a potential difference between the third waveform element at the end of the contraction and the second waveform element, the difference between the first and second potential differences is decreased when environmental temperature is higher than a first predetermined temperature, and increased when the temperature is lower than a second predetermined temperature.
