Title: Article showing bronzy color
Inventor: KAWANA ATSUO
IPC: C23C14/32
Filed: 1989-02-08
Abstract: PURPOSE:To obtain an article showing a bronzy color and capable of easily providing the same color tone with superior reproducibility by forming a film in which Al is allowed to enter into solid solution in the nitride of one or more metal among Ti, Zr, and Hf on the surface of the above article. CONSTITUTION:An article having a film in which Al is allowed to enter into solid solution in the nitride of the above metals, such as TiN, and which has a structure represented by TiaAlbN (where a+b=1) on the surface is provided. In this case, the color of the film when the atomic concentration of Al ranges of 0<b<=0.6 lies in the region of orange, pink, and purplish pink in the chromaticity, but, since this film has brightness, this film appears to have a so-called bronzy color. Further, this film can provide a bronzy color of the same color tone with superior reproducibility by controlling the color tone by changing the concentration of Al to be allowed to enter into solid solution. Moreover, although the formation of this film may be carried out by the known method, it is desirable to adopt an ion plating method at the time of forming films requiring particularly high adhesive strength.

Title: Continuous colorimetric analysis method and apparatus
Inventor: KOSAKA HIROSHI
IPC: G01N21/78
Filed: 1989-02-08
Abstract: PURPOSE:To enable a density analysis in a short time by diffusing a reagent which has flown into a solution, into the solution to take an image of a coloring distribution generated by the diffusion phenomenon with a TV camera. CONSTITUTION:A reagent inflow apparatus 1 makes a fixed amount of an reagent flow continuously into a sample solution passage 2. As the passage 2 is set inclined, a sample solution fed thereinto with a constant flow pump 3 flows at a fixed flow velocity. This flow allows a wider expanse of the reagent toward the downstream. As a density of the reagent becomes lower than a certain value with respect to the sample solution, a hue change occurs with the action of an indicator in the reagent. As a result, a density distribution of the reagent appears as coloring distribution. This coloring distribution is taken as image with a camera 5 to be inputted into an image processor 6. Then, a colored part and non-colored part are binary coded according to brightness respectively to determine areas and an area ratio. A brightness distribution is determined in the image too. The area, an area ratio and the brightness distribution thus obtained undergo a comparison with known values at a calculation or a sampling to perform a density analysis by correction.

Title: Charged particle beam device
Inventor: GOTO NOBUO
IPC: H01J37/09
Filed: 1993-02-17
Abstract: PURPOSE:To realize a charged particle beam device which can prevent a drift of the charged particle beam resulting from a throttling. CONSTITUTION:An electron beam limited by a throttle 15 is radiated on a sample 4, and in this case, the opening angle of the electron beam is made alpha. By such a constitution, a contamination is generated to the throttle 15 by radiating the electron beam, so as to generate a charge-up, and the electron beam is deflected incorrectly or the throttle 15 is deformed by heating. However, the amount of a drift of the electron beam by the charge-up or the deformation of the throttle 15 is reduced by a reduction optical system. Consequently, the amount of the beam drift on the sample 4 is reduced remarkably.

Title: Shutter device
Inventor: TAKAGI JUNICHI
IPC: G03B9/10
Filed: 1989-02-07
Abstract: PURPOSE:To prevent light from leaking from an exposure opening even when a release lever is returned to its initial position by making the fulcrum of rotation of a coupling part slidable to a base plate so that the rotating force to the opening side of the coupling part is absorbed. CONSTITUTION:A long support hole 34 is formed right below a rectangular opening 30, a pin 36 implanted in a shutter board 12 is inserted, and the coupling member 14 is supported rotatably on the pin 36. The support hole 34 is formed in a long-hole shape, so the coupling member 14 is slidable to the pin 36. Thus, the clockwise rotating force of the coupling member 14 when the exposure opening 22 is closed is absorbed to prevent the exposure opening 22 from being open. Consequently, no light leaks from the exposure opening 22 when the release lever 28 is returned to its initial position.

Title: Scanning electron microscope
Inventor: IIDA NOBUO
IPC: H01J37/28
Filed: 1992-02-14
Abstract: PURPOSE:To realize a scanning electron microscope which is simple in structure and can avoid the influence of charge-up of a sample even when the sample is large. CONSTITUTION:When the surface of a sample 2 is charged up with positive electricity, a negative voltage is applied to an electron reflecting plate 4 from a power supply 6. As a result, a reflected electron and a secondary electron generated by an electron beam applied to the sample 2 to move towards the reflection plate 4 are returned towards the sample 2 by an electric field formed with the reflection plate 4. Accordingly, an electric field formed in front of the sample 2 by the surface of the sample 2 charged up is relaxed, and the secondary electron becomes easy to be emitted from the surface part of the sample 2 with radiation of a primary electron beam EB. When the surface of the sample 2 is charged up with negative electricity, a positive voltage is applied to the reflection plate 4 from the power supply 6. As a result, the electric field in front of the sample 2 is relaxed by the electric field formed with a positive voltage applied to the reflection plate 4, and the secondary electron becomes easy to be emitted from the sample.

Abstract: PURPOSE:To precisely measure the depth of buried material by providing a trench monitoring pattern having the same depth as a trench formed in the inside of an element, the width of which pattern satisfies a specified relation with the diameter of a light beam spot. CONSTITUTION:A trench monitoring pattern having the same depth as a trench formed in the inside of an element is provided, whose pattern width W satisfies a relation W>=1.5XD (where D is the diameter of a light beam spot). On a semiconductor wafer 1, a chip region 2 on which an element is formed, and a dicing region 3 to divide the chip region 2 are arranged. Three trench monitoring patterns 4 of width W=2.5mum are formed by etching a silicon substrate 5. In these trenches, a thin SiO2 film 6 is formed, and polysilicon material 7 is buried therein. This buried depth is measured by a fine shape measuring instrument using semiconductor laser light whose beam diameter is 1.5mum. Thereby, only the reflected light from the surface of the buried material in the trench can be used for measuring, so that the accurate depth can be measured.

Title: Heat fixing roll
Inventor: TSUKUDA YASUO
IPC: H05B3/00
Filed: 1983-02-22
Abstract: PURPOSE:To obtain a heat fixing roll of a surface film resistor heating type high in reliability and productivity by forming a resistor film on thin plates for electrodes. CONSTITUTION:An electrically insulating film 3 is formed on the main body 5 of a metallic roll by melt spray coating, and both end parts of the body 5 are tapered to prevent both ends from protruding. This electrode thin plate rings 4 are fixed to both ends, and a TiO2 resistor film 2 is formed by melt spray coating. The TiO2 film melt sprayed on the electrode rings 4 sand blased in advance is faster in adhesion strength between the electrode and the TiO2 film than the electrode material melt sprayed on the TiO2 film. As a result, adhesion is enhanced and a masking step accompanied by melt spray coating of the electrode becomes unnecessary, and the manufacturing process is made simple.
