A gas detector including a gas sensitive element that provides an electrical resistance which varies with the type of gas detected and lead wires for conducting the electrical signal from the gas sensitive element. A porcelain tube supports the gas sensitive element the lower part of which is positioned within a slot in the tube. Through holes in the tube receive the lead wires. A housing encloses the tube. Only the upper part of said gas sensitive element which is not positioned within the tube is provided with electrodes.

A gas component detector having a gas component detecting element made of sintered metal oxide for indicating an electrical resistance according to the components of a gas to be detected. A pair of electrodes transmit the electrical resistance indicated by the gas component detecting element and a ceramic tube has through-holes into which said pair of electrodes are inserted. The ceramic tube has a cylindrical ceramic heater which is prepared by having a piece of wet ceramic sheet on which a print pattern is formed with metal paste for forming a heat generator wound on and bonded to the outer wall of the ceramic tube before sintering. The heater is then sintered to be integral with the ceramic tube.

A navigation system for easily determining defective positions is provided. In the case of CAD navigation to defective positions, logical information for indicating defective positions is created in a CAD format, instead of CAD data of physical information indicating circuit design. Specifically, by attaching marks such as rectangles, characters, or lines, to an electron microscope image with software, quick navigation is performed with required minimum information. By using created CAD data, re-navigation with the same equipment and CAD navigation to heterogeneous equipment are performed.

A semiconductor testing method capable of quickly counting semiconductor cells in which a seemingly horizontal or vertical line is drawn with a mouse, and raster rotation is performed in alignment with the closer axis. After that, the stage is horizontally moved, pattern matching is performed on an image on a position where the image should be disposed, and an angle is adjusted. The stage is moved evenly along the X-axis and the Y-axis, achieving a movement to a destination like a straight line. In synchronization with the smooth movement of the stage, a cell is surrounded in a rectangular frame by a ruler, and the number of cells is displayed with a numeric value.

An object of the present invention is to obtain a clear absorbed current image without involving the difference in gain of amplifier between inputs, from absorbed currents detected by using a plurality of probes and to improve measurement efficiency.In the present invention, a plurality of probes are brought in contact with a specimen. While irradiating the specimen with an electron beam, currents flowing in the probes are measured. Signals from at least two probes are input to a differential amplifier. An output of the differential amplifier is amplified. On the basis of the amplified output and scanning information of the electron beam, an absorbed current image is generated. According to the invention, a clear absorbed current image can be obtained without involving the difference in gain of amplifier between inputs. Thus, measurement efficiency in a failure analysis of a semiconductor device can be improved.
摘要:
The texture of a starchy food (for example, biscuits, cookies, cakes, breads, cream puffs, coated and fried foods, snack foods, wheat noodles, Chinese noodles, etc.) is highly improved by using soybean protein in a smaller amount than in the conventional methods. The effect of improving the food texture somewhat varies depending on the water activity of a food. In the case of a food having a high to moderate water content, it is intended to achieve a soft texture, a favorable feeling on the tongue and a high meltability in the mouth. In the case of a food having a low water activity such as baked goods or toast, on the other hand, it is intended to achieve a crispy and light texture. In the case of wheat noodles and Chinese noodles, it is intended to achieve a flexible texture with an adequate elasticity. By using soybean protein in a smaller amount than in the conventional methods, it is intended to sufficiently relieve troubles (loss in the product volume and worsening in appearance) and poor handling properties (lowering in workability) accompanying the use thereof in a large amount. A starchy food material or a starchy food is obtained by adding acid-soluble soybean protein to a starch material such as wheat flour or starch. The acid-soluble soybean protein can be used in an amount of from 0.05 to 7% by weight based on the starchy material.
