Title: Probe of inner color
Inventor: FELDMAN SANDRA FREEDMAN
IPC: G01J3/50
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To improve a method for measuring and adjusting color when producing a polymer product from a base resin and a pigmenting agent. SOLUTION: The configuration of a probe 30 for measuring the color of the inside of a sample 22a of a substance with a certain refractive index is disclosed. The probe 30 includes a light source 36 for emitting light beams 38 toward the sample 22a. A color sensor 40 is arranged obliquely against the light source 36 and is pointed toward a common probe zone 42 including the sample 22a. The light source 36 and the sensor 40 are aligned optically so that they form, for the zone 42, an incidence angle and a reflection angle that are essentially equal to the Brewster's maximum polarization angle 8 for the refractive index of the sample 22a for measuring the inner color of the sample 22a for the reference plane in the probe zone 42.

Title: Sample holding carrier for fluorescent x-ray analysis, and fluorescent x-ray analysis
Inventor: MORI MASAMICHI
IPC: G01N23/223
Filed: 1993-08-18
Abstract: PURPOSE:To improve the sensitivity of analysis by forming sample holding spaces among a plurality of sheet-shaped articles. CONSTITUTION:Since a liquid sample is held not only on filter paper 2 itself but also in the mutual spaces S of paper 2 because a plurality of filter paper 2 is superposed and the sample holding spaces S are formed, the volume of the filter paper 2 reaches approximately quintuple or sextuple as a whole. On the other hand, the increase rate of the thickness in total of paper 2 in a sample holding carrier 1 is made smaller than that of the quantity of the liquid sample held. Consequently, the quantity (intensity) of fluorescent X-rays generated can be augmented while the increase of a background can be inhibited, thus improving the sensitivity of analysis. The sensitivity of the analysis of a heavy element, in which fluorescent X-rays B2 generated from a deep section must be also detected, is enhanced remarkably because the layer of a sample 6 is thickened particularly. Since the sample (a salute) 6 is also dispersed and raised to both surfaces of the carrier 1 and the spaces S, unevenness in the thickness direction of the sample 6 is reduced, and the accuracy of quantitative analysis by a calibration curve method is also made better than the case of the usage of one thick filter paper.

IPC: B41F33/14
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for mask printing which enable reduction of a printing object material to be removed as a defective. SOLUTION: An apparatus for mask printing comprises a printing device, a mask positioning-supporting device, a wiring board supporting-elevating device, an inspecting device, a mask cleaning device, a carrying device, etc. A printed wiring board carried by the carrying device is positioned and supported by the wiring board supporting-elevating device and solder paste is printed thereon by the printing device in a state wherein the board is brought into contact with a mask. After the printing, the state of printing is inspected by the inspecting device and, when the amount of printing is insufficient, the mask is cleaned automatically by the mask cleaning device. The solder paste being printed again on the printed wiring board after the cleaning, inspection is executed after the printing, and a printing operation is stopped when a printing fault still remains.  By this re-printing, removal of the printed wiring board from a manufacturing line owing to the insufficiency of the amount of printing can be avoided. The inspection may be conducted also at a place apart from the place where the mask printing is executed.

Title: Vacuum deposition method
Inventor: ONO YUTAKA
IPC: C23C14/24
Filed: 1994-09-21
Abstract: PURPOSE: To efficiently vacuum-deposit for a long period with stable arc discharge by preventing the deformation or fusion of a cathode tip part and the deformation of the cathode itself in a vacuum deposition method for forming a metal deposited film on the surface of a base material to be deposited by arranging the base material to be deposited, a metallic body as an anode and a long length metallic rod as the cathode in a vacuum vessel and arc discharging by impressing DC voltage between the anode and the cathode to evaporate the low m.p. metal from the cathode.

Since the cathode 40 is provided with the high m.p. metal-made core material, the cathode is high in rigidity and strength and free from the deformation. The tip part 41A is not deformed or fused since the high m.p. metal-made core material is exposed on the surface.

Abstract: PURPOSE:To make an alignment with high precision feasible by a method wherein bar marks are arranged on at least three corresponding positions on two surfaces while the relative positions of bar marks on the corresponding positions of respective surfaces are optically detected to make the alignment by means of moving one surface according to the results of detection. CONSTITUTION:An inspection optical system 15 arranged over an alignment mark projects the light of a light source 12 on an object lens 14 through a halfmirror 13 to irradiate a mask alignment mark 3 under a mask 1 and a wafer alignment mark 6 on a wafer 2 from the object lens 14. The reflected light of said light is projected on a CCD 9 above-positioned with the bars of alignment marks 3, 6 arranged perpendicular to the scanning direction through the intermediary of the object lens 14 and the halfmirror 13 to detect the alignment marks 3, 6. Then the time interval omega1 between the wave form centers of detection signals 16 of mask alignment mark 3 and the other detection signals 17 of wafer alignment mark 6 or the distance between corresponding marks are measured. Finally the alignment is made by means of moving at least one of these two marks according to the results of measurement.

Title: Method and device for accumulating dielectric film
Inventor: EDOWAADO ARAN DEIN
IPC: C23C16/50
Filed: 1990-08-30
Abstract: PURPOSE: To obtain a deposited layer of a uniform thickness by placing a semiconductor wafer on a surface considerably extending from its end at the time of plasma deposition of the layer of a silicon oxide material on this wafer.  
     CONSTITUTION: The first surface of the wafer 13 supported on a wafer susceptor 12 is exposed to the plasma 14 in reactive gaseous flow 16 heading toward a direction orthogonal with this surface by a gas introducing member 15, by which the layer of the silicon oxide is deposited on the surface. In this method, the wafer 13 is coaxially disposed on the surface of the susceptor 12 considerably larger (≥0.5 inch) than the diameter of the wafer. Since the layer formed by this method has the uniform thickness, the method is particularly preferable in a post treatment using time etching as in the formation of a window or vice for electrical contact reaching the thickness of the layer. The need for flattening is generally lessened or omitted in the post treatment for which the uniformity and flatness of the surface are useful.

IPC: H04L29/08
Filed: 1986-09-29
Abstract: PURPOSE:To realize the automatic incoming by controlling the power supply of a personal computer and starting a communication program when the personal computer receives incoming. CONSTITUTION:When an adaptor 2 has an incoming, the incoming signal is transmitted to a control circuit 12 via an interface circuit 11.

Furthermore the circuit 12 turns on a power supply switch circuit 13. A CPU 19 identifies that the circuit 13 is started by the incoming and then outputs a response signal to show the start of a communication program. Receiving said response signal, the circuit 12 sends a response signal to a network via the circuit 11. Thus a persona computer 1 set at the transmitting side has communication with the adaptor 2.
