Title: Compensatory preprocessing method for digital image for inverse video in digital display with limited performance
Inventor: EDOWAADO MUKA
IPC: H04N7/18
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain the method to compensate a loss of image quality due to a high level surrounding light ahead of time by generating a signal of an attenuated low frequency component from image data and an amplified signal with a high frequency component and synthesizing them. SOLUTION: An image data file 22 storing digital image data of an image source 20 is stored in a computer data memory 26. Based on an image processing algorithm stored in a computer instruction memory 30, a CPU 32 processes image data stored in the memory 26. The CPU 32 discriminates a low frequency component signal in the digital image signal and generates the signal with the attenuated low frequency component, and discriminates the signal with a high frequency component to generate a signal with the amplified high frequency component. When the signals are synthesized and an image is displayed on a CRT display device 24, the image signal with improved luminance dynamic range and spacial frequency characteristic is generated.

Abstract: PURPOSE:To produce silicon nitride whisker in high purity and high yield, by packing a raw material which contains silicon, is thin walled and having voids in a tray, moving the same intermittently in a specific temp. region in a non- oxidative atmosphere to remove impurities, then nitriding the same. CONSTITUTION:A tray 7 contg. a raw material 8 (e.g.; chaff or the like) which contains silicon, is thin walled and has the voids sufficient for the growth of whiskers is placed in an inlet and substitution chamber 1 for gas into which a non-oxidative gas (e.g.; nitrogen or the like) is fed. A door 9 is pulled up and the tray is moved into the small chamber 3 in the lowest temp. part of a furnace body where the temp. increases stepwise. Gaseous nitrogen is blown through a blowing port 4 and the material 8 in the tray 7 is heated gradually by the heating gas through the fine holes 6 in the bottom part. The tray is moved intermittently in an about 400-1,300 deg.C temp. region whereby the material is preheated and the impurity components therein are scattered away simultaneously. The tray is thereafter moved intermittently in an about 1,350-1,450 deg.C temp. region to nitride the material and is then cooled at an ordinary temp. The silicon nitride whisker are obtained in high purity and high yield.

Title: Laser cutting method and device
Inventor: NISHIKAWA YUKIO
IPC: B23K26/38
Filed: 1990-03-07
Abstract: PURPOSE:To cut glass to an arbitrary shape without requiring a cutting width by forming a continuous marking-off line on at least one surface of the glass and irradiating the marking-off line with a laser beam. CONSTITUTION:The laser beam 2 emitted from a CO2 laser oscillator 1 is made incident on a condenser lens 4 by a reflecting mirror 3 and the glass plate 5 is irradiated thereupon with this laser beam. An X-Y table is moved in such a manner that the laser spot comes into the marking-off line 6 of the desired shape, by which the glass plate 5 is cut to a prescribed shape. The cutting line 8 is progressed by the movement of the laser spot at this time but the cutting mechanism is contributed by the elastic distortion arising form a local temp. rise and, therefore, the propagation of a crack arises behind the position irradiated with the laser. The crack is more easily generated by the effect of residual strains if the marking-off line is formed by mechanical means.
