Title: Electron beam scanning type light bulb
Inventor: URANO SHIYUUJI
IPC: G02F1/163
Filed: 1983-06-08
Abstract: PURPOSE:To obtain a display element having high resolution with a comparatively simple drive circuit by irradiating the specified area of electrochromic layer with the electron beam emitted from the electron gun in the cathode ray tube through a transparent electrode layer, a photoconductive layer and an electrolyte layer. CONSTITUTION:A transparent electrode layer 4 consisting of indium-tin oxide layer, an electrochromic layer 5 consisting of tungesten oxide layer, an electrolyte layer 6 consisting of tantalum oxide, a photoconductive layer 7 consisting of amorphous silicon or cadmium sulfide and a transparent electrode layer 8 are sequentially formed by stacking them from the internal surface of glass bulb 2 of cathod ray tube 1. The specified area of such photoconductive layer 7 is irradiated with the electron beam 12 which is emitted from the electron gun 11 in the side of transparent electrode layer 8 and is deflected by the deflection coil 13. Thereby, electron density of photoconductive layer 7 increases. When a positive voltage is applied to the transparent electrode layer 8 while a negative voltage to the transparent electrode layer 4 at this time, the electrochromic layer 5 of such area changes into blue-black in color and thereby data can be written.

Title: Defect inspection device
IPC: G06T5/20
Filed: 1992-03-30
Abstract: PURPOSE:To automatically detect a defect to extract a region including the defect so that its shape, type, etc., can be highly accurately discriminated. CONSTITUTION:An address of a defect is obtained based on a differential image, and a first threshold TH1 determined from a total density distribution of the differential image and a second threshold TH2 obtained from an average density value of a vicinity region of a pixel of interest are used to obtain a third threshold TH3 for each pixel of interest, which is used to binarizing each of the pixels of interest. The pixels of the region including defect addresses of regions obtained by this binarization processing are all painted by values indicating a defect. The third threshold TH3 is obtained by TH3=TH1-k(TH1-TH2) for example. Shape correction such as compressing, expanding, embedding, etc., can be performed immediately after the binarization processing.

Abstract: PURPOSE:To eliminate the influence of measuring system frequency characteristics and then measure the elastic property of a sample accurately by changing the amplitude of a burst wave so that the reflection signal intensity from a sample at each frequency can be maintained to be constant while changing the frequency of a high-frequency burst wave. CONSTITUTION:A variable output oscillator 12 transmits a high-frequency burst wave with an amplitude A (fstart) to an acoustic lens 1 via a pulse modulator 6 according to a control signal from a control/operation circuit 10. The ultrasonic reflection signal is received 8 and a reception signal intensity V(fstart) is stored in the operation circuit 10. Then, a transmission amplitude A(fstart+f0) of the oscillator 12 is changed so that the reception signal intensity V(fstart+f0) is equal to V(fstart) when frequency is equal to (fstart+f0 and the value is stored. A curve A(f) obtained by repeating the similar measurement for n times is equivalent to V(f)* although the maximum and minimum values are inverted as compared with those of V(f)*, thus measuring the elastic property of a sample 4 since no measurement system frequency characteristic V(f)s is included.
