摘要:
A coaxial type impedance matching device includes a matching device body including an external conductor and an internal conductor arranged in the external conductor, an input side dielectric disposed in the matching device body and including a first dielectric and a second dielectric, and an output side dielectric disposed in the matching device body and including a third dielectric and a fourth dielectric. Distance between opposed surfaces of the first dielectric and the second dielectric is a predetermined distance, which is in a range of Nλ/4−λ/6 to Nλ/4−λ/6, where λ represents a guide wavelength of an input signal in the matching device body and N represents odd number. Distance between opposed surfaces of the third dielectric and the fourth dielectric is the predetermined distance.

A plasma generating method generates plasma in a treating chamber by controlling a high-frequency generating unit to generate a high-frequency signal and by feeding the high-frequency signal to the treating chamber through an impedance matching device. The plasma generating method includes controlling the impedance matching device, when the plasma is generated in the treating chamber, so as to satisfy a preset matching condition, and then controlling the high-frequency generating unit to generate and feed the high-frequency signal of the power generating the plasma, to the treating chamber.

For plasma generation, an impedance matching device and a process of controlling and detecting the impedance matching device are provided to satisfy a preset matching condition. The impedance matching device includes a tubular external conductor and an internal conductor disposed therein, a matching device body including a plurality of dielectrics, a moving mechanism, a storing unit for storing a data table, a measuring device, and a calculation control unit. The impedance detecting process includes inputting a progressive wave and a reflected wave outputted by a directional coupler connected to an object to be matched, generating different signals, and mixing the signals to determine relative phase differences and amplitude ratios of the signals, and detecting an input impedance of the object to be matched on a basis of the detected amplitude ratios and that of a true phase difference between the progressive wave and the reflected wave that is detected by referring to a relationship prepared in advance.

A focus detecting method includes the step of projecting the real image of an observation object including a plurality of object patterns onto an image pickup device through an optical system and producing image data from an output of the image pickup device, the step of calculating correlation values of the image data of each of the plurality of object patterns and the image data of a prestored reference pattern while varying the relative positional relation among the image pickup device, the optical system and the observation object in the direction of the optical axis of the optical system, and the step of judging a relative positional relation giving the maximum correlation value as an in-focus state. An apparatus is provided for carrying out the above-described focus detecting method.
摘要:
Disclosed is a computer in which an error caused by an intermittent failure is corrected by using a misprediction recovery mechanism which performs recovery processing if, after having predicted a branch destination of a branch instruction and speculatively executed an instruction at the predicted branch destination, it turns out that the branch prediction was wrong. The computer includes an error detection mechanism for detecting an error in logic operation of the computer, and an instruction re-execution mechanism for correcting an error caused by an intermittent failure when an error is detected by the error detection mechanism, by restoring the computer, using the misprediction recovery mechanism, to a state that existed before the occurrence of the error, and by re-executing a sequence of instructions including the instruction where the error is detected.
摘要:
In the pattern matching method, when a reference pattern is extracted from the reference picture, check search is carried out repeatedly a plural number of times while conducting picture compressions on the reference picture with the compression start position being changed to obtain correlation values between the reference picture and the reference pattern. Based on the correlation values obtained by the check search, the number of times of search to be done actually and the picture compression ratio for the actual search are determined.
摘要:
A system for adjusting a performance of an information processing apparatus which provides a unit indicating a target performance value, a unit generating a corresponding performance control pulse in accordance with the target performance value, and an execution control unit which alternately sets an execution period and an execution inhibiting period in accordance with the performance control pulse. The unit which generates the performance control pulse sets a ratio of a pulse width and a pulse period of the performance control pulse coincide with the target performance value.
