In a blade of a blade server, power is supplied from a power distributing unit to an internal circuit, and also supplied to a capacitor to charge the capacitor. If power consumption of the blade server is high and a process load on a blade is also high, power is supplied to the internal circuit from both the power distributing unit and the capacitor. If the process load on the blade is low, power is supplied to the internal circuit only from the power distributing unit.

A laser apparatus (100) for performing the laser machining operation by condensing the laser light output from a laser oscillator (3) is disclosed. A laser output value calculation unit calculates a laser output value (L1) based on a command value (L0) issued to a laser oscillator (2). A temperature change estimating unit (31) estimates the temperature change or the temperature (Te) of specified component element(s) (7a, 7b) of the laser apparatus based on the elapsed time (t) and the laser output value calculated by the laser output value calculation unit. An adjusting unit (32) adjusts the conditions for controlling the laser or the conditions for laser machining based on the temperature change or the temperature of the specified component element estimated by the temperature change estimating unit. A stable laser machining operation is performed without a temperature sensor. The laser output value (L1) may be measured by a laser power sensor (5).

The counter steer detecting method includes the steps of detecting a steering angle by a steering angle sensor, detecting a lateral acceleration by a lateral acceleration sensor, and determining counter steer according to the steering angle detected by the steering angle sensor and the lateral acceleration detected by the lateral acceleration sensor on the basis of a counter steer determination area table indicating whether or not the counter steer is on in relation to the combination of steering angle and lateral acceleration.

When making a clinical diagnosis using gene expression profiles or the like obtained from a DNA microarray, multidimensional data is visualized on a scatter chart so that outliers can be identified and the state of classifications can be recognized. A method comprises calculating said separating hyperplane by applying said pattern recognition algorithm to said training set that is entered; displaying the labels of two axes of said scatter chart in two or three dimensions; applying data of which the group it belongs to is unknown to said pattern recognition algorithm as a test set in order to determine the group the data belongs to; displaying a plot representing the data in said training set and a plot representing the data in said test set on a two- or three-dimensional scatter chart, in different manners for individual groups; and displaying said separating hyperplane by mapping it to said scatter chart.

A laser machining apparatus capable of removing spatters and slugs produced in piercing and rising supply pressure of blow gas sufficiently without hindering a jet of assist gas. A piercing assist jig can be turned and moved up and down by a rotary air cylinder and an extendable air cylinder which are attached to a machining head. When piercing is to be performed, the piercing assist jig, which is in a position where it does not interfere with the machining nozzle and the workpiece, is turned to make a center of a hole of the piercing assist jig coincide with a center of the machining nozzle. Then the machining head is moved down to a piercing position, and the piercing assist jig is pressed on a workpiece. Then, a laser beam is irradiated and assist gas is jetted, and also blow gas is jetted from a blow gas supply opening so that the blow gas flows with the assist gas therebetween. Spatters and slugs flying up in the process of piercing are removed by the blow gas without hindering the piercing.

An acceleration change determination device determines whether or not a change in acceleration at a joint in blocks in a matching program decoded by a pre-processing and arithmetic device is more than a predetermined value. When the change of acceleration is found to be more than the predetermined value, the speed commanding device adjusts the speed to lower commanded speed at points immediately before and immediately after the joint in blocks. A movement control device outputs an interpolation pulse to individual moving axes so that the speed becomes the commanded modified speed, thereby controlling a servo motor.

In a laser machining device for cutting a round hole in a workpiece employing a machining program, a movement path includes a section from point P.sub.1 to point P.sub.2 (passing a hole previously formed in a workpiece) and reaches point P.sub.3 on a circle (40) to be cut. A section P.sub.2 -P.sub.3 of the path is not a simple circular arc but is a curve whose radius of curvature gradually becomes approximate to the radius of a circle 40 to be cut as it gradually decreases towards the end point (P.sub.3) from the start point (P.sub.2) where the radius of the curvature is largest. Thus, the change in acceleration at points P.sub.2 and P.sub.3 of the section P.sub.1 -P.sub.2 -P.sub.3 of the path can be controlled to low levels.
摘要:
A laser beam machine capable of carrying out proper tracing control with ease. A tracing control circuit of a CNC device executes tracing control upon receiving a tracing start command from a CNC main circuit. Specifically, the control circuit is supplied with a detection signal from a height detector and outputs a drive signal to a motor such that the height of a machining head is kept within a predetermined range. A workpiece detector is provided for detecting the presence or absence of a workpiece at the distal end of the machining head. When the workpiece at the distal end of the machining head drops as the machining operation advances, this is detected by the workpiece detector, which then outputs a detection signal to a tracing interrupt circuit. On receiving the detection signal from the workpiece detector, that is, information indicating that there is no workpiece at the distal end of the machining head, the tracing interrupt circuit outputs a tracing interrupt signal to the tracing control circuit. When supplied with the tracing interrupt signal, the tracing control circuit interrupts the tracing control.

Surface treating agents comprising of an organic titanium compound containing at least one fluoropolyether radical linked by carboxy groups to the titanium and at least one hydrolyzable group, such compounds being obtained by reacting a fluoropolyether having one or more carboxylic groups with a titanium compound having at least one group able to react with carboxylic group and at least one residual hydrolyzable group per titanium atom. The surface treating agents have not only superior surface activity and anti-corrosion properties for the metal surface but are also chemically stable.
