摘要:
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.

An information input device includes a display unit that has a display screen and displays an image, and a touch-panel that is arranged on the display screen and specifies a designated position on the display screen. The display unit displays any of first, second and third screen images depending on the state of information input device, and the first and third screen images have a prescribed area on which information including the same character, sign or figure is displayed. If a position in the prescribed area is specified by an input unit while the first screen image is being displayed, the display unit displays the second screen image, and if a position in the prescribed area is specified while the third screen image is being displayed, the display unit maintains the display of the third screen image
摘要:
In an apparatus for fabricating a carbon coating, an object such as a magnetic recording medium is disposed on a side of an electrode connected to a high-frequency power supply. Ultrasonic vibrations are supplied to the object. Discharge is generated between the electrode connected to the high-frequency power supply and a grounded electrode to fabricate a carbon coating on the surface of the object. Also, an electrode interval is set to 6 mm or less, pressure between the electrodes is set to 15 Torr to 100 Torr, whereby high-density plasma is generated to form an ion sheath on an anode side. Therefore, a coating is fabricated on the surface of the object by bombardment of ions.

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).

摘要:
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.
