    • The present invention provides a traveling speed reduction gear lubricating oil cooling device that enables optimal temperature control for lubricating oil delivered via a lubricating oil pump that can be started up with a relatively small motor without running the risk of damage to an oil cooler in a cold work environment even when a temperature sensor that detects the temperature of the lubricating oil is installed outside a wheel mounting sleeve. During a startup operation, provided that the detected temperature at a traveling motor is higher than the reference temperature, the lubricating oil pump is driven at a speed in a lower speed range relative to the normal operation speed range. In addition, during the startup operation, the rotation speed of the drive motor for the lubricating oil pump is increased in correspondence to a rise in the temperature detected by a lubricating oil temperature detection sensor.
    • 本发明提供了一种行驶减速齿轮润滑油冷却装置,其能够对通过润滑油泵输送的润滑油进行最佳温度控制,所述润滑油可以用相对较小的电动机起动,而不会在冷气中产生损坏的油冷却器的风险 即使将检测到润滑油的温度的温度传感器安装在车轮安装套筒外部的工作环境中。 在启动操作期间,只要行驶马达的检测温度高于参考温度,则润滑油泵以相对于正常运行速度范围的较低速度范围内的速度被驱动。 此外,在启动运转中,与润滑油温度检测传感器检测出的温度升高对应地,润滑油泵的驱动电动机的转速增加。

    • An undulation inspection device of the present invention includes: illumination means (line light source 2) that subjects, to illumination, an object to be inspected; light intensity acquisition means (area sensor 3) that acquires light intensity distribution of light that comes, in response to the illumination, from a surface of the object to be inspected; image capturing means (line sensor 4) that obtains only predetermined light out of light that comes from the surface of the object to be inspected; adjustment means (image processing section 20 and light source drive controlling section 21) that adjusts the illumination means (line light source 2), based on the light intensity distribution that is obtained from the light intensity acquisition means; and determination means (defect determination processing means 23) that determines a state of undulation that is formed on the surface of the object to be inspected, based on a result of capturing an image by the image capturing means after adjustment of the illumination means. This makes it possible to provide an undulation inspection device capable of inspecting simply and at a high precision a state of undulation (a difference in film thickness) on a surface of a large substrate (e.g., color filter substrate).

    • Embodiments of the invention provide an inexpensive magnetic head tester employing component parts of a production HDD and capable of exercising functions very close to those of a production HDD. In one embodiment, a magnetic head tester employs the VCM actuator and the control circuit of a production HDD and has a lightweight, simple HGA fixing mechanism mounted on an actuator arm. The HGA fixing mechanism fixes an HGA to the actuator arm by a method using a very light holding spring mounted on the arm, a method of mechanically clamping an HGA by using air pressure, or a method of fixing an HGA to the arm by elastically deforming a rubber clamping member by air pressure. Servo control is achieved by the actuator of a production VCM. An end part of the VCM actuator is stopped by a stopping mechanism and is held by a holding spring to prevent the runaway of the VCM actuator. Servo control is performed by balancing the driving force of the VCM and the resilience of the spring.
