Patent JP-H0915174-A (JP)
Title: Method for chemical analysis and equipment for pretreatment therefor
Inventor: SHIMONO TSUGIO
IPC: G01N1/28
Filed: 1995-06-30
Abstract: PURPOSE: To condense a chemical by a quick, simple and safe pretreatment operation and thereby to enable execution of an analysis with high accuracy, by a method wherein after the chemical put on the surface of a wafer is evaporated by heating, a very small quantity of recovery solution containing fluoric acid is dropped onto the surface of the wafer, scanning is made thereon and an evaporation residue is recovered. CONSTITUTION: The pressure inside a closed vessel 1 is reduced by a vacuum pump 7 and a silicon wafer 3 is heated by a hot plate 2 to condense a chemical 4 by evaporation. Then, a very small quantity of recovery solution containing 77 fluoric acid is dropped onto the surface of the wafer 3, scanning is made all over the surface of the wafer 3 so as to dissolve and recover an evaporation residue, and impurities in the recovery solution are analyzed. Since the surface of the wafer 3 has a high water repellency, according to this method, the dropped recovery solution gathers like balls and moves smoothly on the surface of the wafer 3, and since the recovery solution also has a high solubility, the whole quantity of the evaporation residue can be recovered even by a very small quantity thereof.  Thus, condensation of a high multiplication rate can be attained even when the quantity of the chemical to be condensed is small. By executing the condensation under the reduced pressure by using the wafer 3, accordingly, even a high-boiling chemical such as a sulfuric acid can be condensed quickly at a relatively low temperature and an analysis with high sensitivity can be performed.

Title: Solid-state image pickup device
Inventor: AWAMOTO KENJI
IPC: H04N5/232
Filed: 1987-07-01
Abstract: PURPOSE:To reduce the number of parts of an automatic focussing mechanism and to constitute it with small size and inexpensive by using a half mirror for light transmittance plate, and disposing two lines of line sensors on the reflecting beams axis of the half mirror. CONSTITUTION:Either of two pieces of light transmittance plates 20 is constituted of a half mirror, and the two lines of linear line sensors 131, 132 are provided on the reflecting beam axis 251, 252 that are apart by prescribed angle (+ or -DELTAtheta) based on the fine vibration of the plate 20. When the scanning of view scope in the vertical direction of a solid-state image pickup element 3 is executed by means of the fine vibration of the light transmittance plate 20, a light beam reflected by the plate 20 is made incident on the line sensors 131, 132, so that the contrast between planes 151, 152 in front and rear of the solid-state image pickup element 3 can be virtually detected out of output signals from the line sensors 131, 132. From thus detected contrast, the focus position of a beam convergence lens is decided to focus automatically. Therefore, no half mirror or no beam splitter dedicated to the automatic focussing are necessary, hence the number of parts is reduced, and the device can be constituted with small size and inexpensive.

Title: Surface treatment of fluoride glass base material
Inventor: KOGO TAKASHI
IPC: C03B37/014
Filed: 1992-06-24
Abstract: PURPOSE:To improve the tensile strength of glass fiber by applying liquid phase etching to the most exterior layer clad part of a cylindrical fluoride glass base material to provide the specified surface roughness. CONSTITUTION:The relationship between the surface roughness and the tensile strength in material compositions of the most exterior layer clad part of a cylindrical fluoride glass parent material is measured to determine the surface roughness meeting the allowable tensile strength. The surface roughness is defined as the average of the absolute values of the differences between the measured distance values from points on one generating line outside the cylindrical glass base material to the central axis of the cylinder and the average radius value. The surface roughness is preferably <=0.05mum. The relationship between the solute concentration and etching time of etching solution (example: hydrochloric acid solution of zirconium oxychloride) and the surface roughness is measured to determine the solute concentration and the etching time meeting the desired tensile strength, permitting liquid phase etching to be performed. According to this method, since the surface corrosion of the base material glass is restrained while controlling the surface roughness of the base material glass, fiber of high tensile strength is obtained.

Filed: 1982-09-24
Abstract: PURPOSE:To correct a fall correction value automatically and to improve weighing precision by calculating a current fall correction value on the basis of the last weighing error and fall correction value. CONSTITUTION:An operation part 11 is operated to input a weighing set value, the initial value of a fall correction value, and a constant to a CPU12.

IPC: G06F15/16
Filed: 1989-06-28
Abstract: PURPOSE: To shorten the latency of storage device read by transferring data requested by a selected CPU to a system control unit(SCU) and checking the validity of data to transfer the data to the requesting CPU and writing it in a selected address of the main storage device of the SCU. CONSTITUTION: In the 'write-read' cycle, only the valid part of data transferred to an SCU 4 in response to the data request from one of CPUs 12 requesting data is written in a main storage device 6 of the SCU, and on the other hand, all of data requested by one of CPUs 12 requesting data is read out from the main storage device of the SCU. Read data is data written in the main storage device 6 of the SCU and includes the valid part of data read by the SCU 4. Thus, the latency of storage device read is shortened in the case that two independent commands and two complete data transfer timing cycles for the main storage device of the SCU 4 are required.

Title: Detector for interlayer short circuiting of electric winding
Inventor: ISHIGAKI YUKIO
IPC: G01R31/72
Filed: 1980-11-28
Abstract: PURPOSE:To detect interlayer short circuting of a winding surely despite presence of fluctuations in terminal voltage by connecting two pieces of impedance elements in parallel with the winding having an intermediate tap and connecting these elements in series, then connecting the intermediate tap and the above- mentioned elements thereby forming a bridge circuit. CONSTITUTION:Two pieces of impedance elements 3a, 3b connected at both ends of a terminal such as troidal magnetic field coil 1 or the like are connected in series, and further these are connected in parallel with an intermediate tap Nc of the winding, whereby a bridge circuit is formed. When short circuiting occurs between the layers of the winding of the coil 1, a difference in internal resistance, impedance, etc. is generated with the tap Nc as a boundary, and the bridge circuit goes unbalance, through which electric current flows. If the unbalance current is detected with a current detecting circut 4, the interlayer short circuiting of the winding of a troidal coil or the like for unclear fusion having fluctuations in voltage between terminals is surely detected.

Here, deionized water is sprayed through a spray nozzle 9 except the effective screen of the panel 1 to remove the graphite then it is sprayed to the effective screen 1b to remove the graphite. Consequently, the light absorbing material is prevented from adhering again to the opening of light absorbing matrix thus to improve the yield of fluorescent screen.

Title: Fiber for transmitting infrared light
Inventor: IMAGAWA HIROSHI
IPC: C30B11/00
Filed: 1982-09-27
Abstract: PURPOSE:To manufacture easily the titled fiber causing hardly deterioration due to repeated bending, by using a solid soln. consisting of a specified mol% of CsBr and the balance CsI as a material. CONSTITUTION:A fiber for transmitting infrared light is made of a solid soln. consisting of CsBr and CsI. The CsBr content is >=95mol% or <=13mol%. The fiber is superior to a fiber made of a simple solid soln. of CsBr or CsI. Since the solid soln. consisting of CsBr and CsI has higher hardness and an extended elastic limit, the deterioration of the fiber due to plastic deformation is reduced when the fiber is repeatedly bent at curvature in a fixed range. It is made unnecessary to use an atmosphere of gaseous halogen or gaseous hydrogen halide requiring troublesome handling when a quartz boat which is advantageous to the manufacture of a high=purity ingot by melting is used.
