摘要:
A camshaft apparatus includes rolling bearings which support a camshaft rotatably, whereby a reduction in torque when an engine is started or is running at low speeds, a reduction in vibration of the camshaft and an extension of the lives of the bearings can be realized. In the rolling bearings, one rolling bearing is made to constitute a main ball bearing which restrains an axial relative movement of the camshaft relative to a shaft case, and the other rolling bearings are made to constitute a plurality of needle roller bearings, whereby a mechanical movement of the camshaft in an axial direction can be restricted in an ensured fashion by the main ball bearing. As to relative displacements due to thermal expansion or contraction of the camshaft and/or the shaft case, an axial relative displacement can be absorbed by needle rollers relatively moving on inter-cam outer circumferential surface areas.

A network system of the present invention includes a switch and a controller. The controller sets a flow entry, in which are defined a rule and an action used to uniformly control a packet as a flow, in a flow table of the switch. The switch determines whether or not to perform a sampling processing to a received packet, in accordance with the flow table setting, and notifies the controller of a sampling result in a case where a sampling processing is performed to the received packet. The controller updates the flow table in accordance with the sampling result and narrows packets to perform a sampling processing.

A pressure regulator, including a housing; a piston axially movably disposed in the housing; a high-pressure chamber; a low-pressure chamber; a regulated-pressure chamber whose pressure biases the piston in a first direction in an axial direction of the housing; a first pilot chamber whose pressure biases the piston in a second direction opposite to the first direction; a second pilot chamber whose pressure biases the piston in the second direction; and a valve mechanism configured such that, by a movement of the piston in the second direction, communication between the regulated-pressure chamber and the high-pressure chamber is permitted while communication between the regulated-pressure chamber and the low-pressure chamber is shut off and such that, by a movement of the piston in the first direction, the communication between the regulated-pressure chamber and the high-pressure chamber is shut off while the communication between the regulated-pressure chamber and the low-pressure chamber is permitted.

The monitoring apparatus includes vibration sensors that detect vibration accompanying machining, a rotation detector and a rotation detection section that detect rotation of a main spindle, and a stability limit and vibration distribution calculation section that creates, on the basis of vibration information obtained from the vibration sensors and a rotation speed of the main spindle detected by the rotation detector and rotation detection section, both a stability limit diagram illustrating a relationship between the rotation speed and a stability limit of the machining and a vibration distribution diagram illustrating a relationship between the rotation speed and the vibration, and displays the created diagrams on a monitor in a vertical arrangement.

In a machine tool having a rotary shaft for use in rotating a tool or a workpiece, a plurality of stable rotation speeds at which the chatter vibrations are expected to be suppressed, and at least one switching rotation speed across which a dynamic characteristic of a rotary shaft system changes are stored. The plurality of stable rotation speeds may be determined from chatter vibrations detected using a vibration detection unit. Optimum rotation speed that is a rotation speed to which a rotation speed of the rotary shaft is changeable without crossing the switching rotation speed is selected from the plurality of stable rotation speeds, and the rotation speed of the rotary shaft is changed to the optimum rotation speed. Thus, chatter vibrations generated during rotation of the rotary shaft can be suppressed effectively.

A vehicle control system for a vehicle includes an engine control device configured to automatically stop an engine of the vehicle during running of the vehicle; and a brake control device configured to execute an assisting control for increasing an output of a brake for restraining rotation of a wheel of the vehicle when a starting condition for starting the assisting control is satisfied, such that an amount of the output increased by execution of the assisting control becomes larger than an amount corresponding to an operational state of a brake operating member of the vehicle. The brake control device includes an automatic-stop assisting control portion configured, during an automatic stop state in which the engine is automatically stopped by the engine control device, to execute the assisting control in a manner different from a manner in which the assisting control is executed during an activation state of the engine.

A color adjustment system for a display device includes a computer device, and a display device for displaying an image. The display device selectably displays a plurality of color temperature color presets. The computer device makes a white point adjustment to the display device, based on a color temperature color preset selected from among the plurality of color temperature color presets by a selecting operation from the computer device.

An operating device includes click feeling generation members provided on a base plate, a pusher that elastically deforms the click feeling generation members, a pressure receiving surface provided on the pusher, a shaft that is operable to tilt to directions with respect to a standing state, and an operating part provided on the shaft and engaged with the deepest part of the pressure receiving surface. The operating part is disengaged from the deepest part of the pressure receiving surface when the shaft is operated to tilt to any of the directions. When the operating part is disengaged from the deepest part of the pressure receiving surface, the operating part of the shaft pushes the pressure receiving surface to move the pusher toward the base plate, so that all of the click feeling generation members are elastically deformed from the first states to the second states.
