Abstract: PURPOSE:To increase the reliability in a measuring result by measuring the temp. distribution of the body to be measured by irradiating a laser beam on the body to be measured and by detecting the infrared ray radiated from the body to be measured. CONSTITUTION:The temp. state at the optional plural specified spots of the body A to be measured is first measured by a thermo-graphical device in order to inspect the external wall state of the body A to be measured of a building, etc. Then, by irradiating a laser beam on each specified spot it is compared with the temp. prior to the irradiation. However, in case of a crack, for instance, being caused on the body A to be measured, a temp. difference is caused between the cracking part thereof and the part where no crack is caused. Even in case of a separation being caused on one part of the body A to be measured the temp. difference is caused between the inner part and wall face. In case of one part of the body A to be measured being deteriorated, moreover, the temp. difference is caused due to the heat absorbing rate varying. The external wall state can be inspected in this way by measuring the temp. difference before and after the laser beam irradiation by heating artificially the external wall of the body A to be measured by the laser beam.

Title: System of electron beam and lithography with low brightness
Inventor: HANSU KURISUCHIYAN PUFUAIFUAA
IPC: H01L21/027
Filed: 1996-09-10
Abstract: PROBLEM TO BE SOLVED: To accomplish high throughput as well as high resolution by using an electron gun for irradiating a part of the circuit pattern on a reticle with electron beams, using fairly low brightness and fairly high general beam currents. SOLUTION: It is insufficient for an application beam system to shorten the path between a reticle 204 and a wafer 224 so as to limit the mutual action of coulomb limiting the throughput. Appropriate resolution can be accomplished only by the remarkable increase of the section of a beam decided mainly by source size. With the half angle of the beam of the same size, the requisites for brightness decrease drastically to about 10<3> A/cm<2> sr. The brightness in this range is necessary for accomplishing the goal of general beam currents in the range of 10μA, while maintaining the stochastic mutual action within the range which does not interfere with the resolution in fine form in the range of under 0.2μm.

Filed: 1991-09-19
Abstract: PURPOSE:To attain the reception over a board band by using a local oscillator similar to that of a conventional tuning circuit in a receiver receiving a sent signal by a frequency division multiplex system. CONSTITUTION:A received signal is divided into a high frequency band and a low frequency band by a branching filter 11. A signal at a low frequency band is given to a mixer 16, in which the signal is frequency-converted by the upper side band heterodyne system and a signal at a high frequency band is given to a mixer 22, in which the signal is frequency-converted by the lower side band heterodyne system. The local oscillation frequency required for frequency conversion is fed respectively to the mixers 16, 22 from a VCO 24. The signal after frequency conversion is respectively inputted to terminals X, Y of a switch 27 and a desired signal is selected and demodulated by a demodulation circuit 31. Since the two kinds of the frequency conversion systems are employed, the demodulation signal has a different polarity. Then the signal of the desired polarity is selected by the switch 32 and outputted.
