摘要： PURPOSE:To make preparation of a molding part easy by a method wherein a molding part which molds a surface excepting an irregular form part of a resin body and an irregular form part corresponding to the irregular form part of the resin body of the molding part are buried freely detach-ably in a surface composing a cavity of a metal mold. CONSTITUTION:A top force 11 is composed of a proper body 13 having a molded surface 13a of a spherical form which molds a surface excepting a three-dimensional projection part 3 of an insulation spacer 1, and four nests 14 which are buried in the molded surface to mold the three-dimensional irregular form part 3 of the spacer 1. A bottom force 12 is composed of a proper body 18 having a molded surface 18a of the spherical form which molds a rear surface excepting the projection part 3 of the spacer 1, and four nests 19 as a three-dimensional projection molding part which molds the rear surface of the projection part 3. The nests 14, 19 are respectively fit freely detachably in an upper force proper body 13 and a bottom force proper body 18 with bolts. Then, only the proper bodies 13, 18 are two-dimentionally worked, and only the nests are three-dimensionally worked. Therefore, the proper bodies 13, 18 and the nests 13, 18 are separately two-dimensionally and three dimentionally worked, and the working will be simplified.

摘要： PURPOSE:To surely prevent a blade section from coming out of an end plate coupling groove at the bottom section due to the molding contraction of the blade section, also prevent the occurrence of a gap between the coupling groove and the bottom section of the blade due to thermal influence during actual compression operations with the leak of gas reduced, and thereby enhance compression efficiency and reliability. CONSTITUTION:A scroll is made up of the end plate section K of a metallic disc for one side surface of which a scroll shaped coupling groove 20 is provided, and of a blade section T made of synthetic resin the bottom section 21 of which is coupled with the coupling groove wherein the most of the section is injection molded in such a way as to be projected in a scroll shape out of the end plate section. The cross sectional shape of the coupling groove 20 and the end plate bottom section coupled with the coupling groove is formed into an inverse taper where the groove width is expanded toward the groove bottom surface from the groove open section.

摘要： PURPOSE:To automatically analyze the kind of foreign matter without supplying a current to a liquid crystal cell by irradiating the transparent substrate of the liquid crystal cell with laser beam to detect the position of foreign matter and irradiating the foreign matter with ultraviolet rays on the basis of the positional data thereof to detect the fluorescence emitted from the foreign matter. CONSTITUTION:A measuring liquid crystal cell 3 is placed on a positioning mechanism 7 to be moved and the entire surface of the cell 3 is irradiated with laser beam 1. The laser beam 1 transmitted through the cell 3 is incident to a photodetector 5. The image data thereof is sent to an image processor 15 and a computer 20 through a television camera 14 to obtain the positional data of foreign matter to be stored in a memory 22. Next, on the positional data of the memory 22, the cell 3 is moved to the position of a broken line to selectively irradiate the position where the foreign matter is present with ultraviolet rays. The microscopic image due to the weak fluorescence generated by this irradiation is caught by a fluorescence microscope 17 and the kind of the foreign matter is judged by the image processor 15 through the camera 14.

摘要： PURPOSE:To enhance the accuracy of a scroll lap by accommodating an end plate having a scroll groove in a metal mold and forming a scroll lap by injection molding from the back surface side of this end plate. CONSTITUTION:An end plate 12 of a disc-type is accommodated in a metal mold 11. A scroll groove 13 consisting of the combination of an involute or a circular arc is formed beforehand on one side surface of this end plate 12. A filler hole 14 is formed on the back surface side of the end plate 12 in the nearly central position of the total length of the scroll groove 13. Under this condition, a scroll lap 16 is formed by injection molding from the back surface side of the end plate 12 through the filler hole 14. The scroll lap 16 is formed with good accuracy because of no obstruction caused by the filler hole 14 and a gas vent hole 15.

摘要： PURPOSE:To secure a scroll blade without heat deformation by forming a projection on a surface opposite to a recess formed on at least one of the both contact faces of a grooved plate and a support plate, and by pressing the projection to be fit into the recess so as to fix the grooved plate to the support plate. CONSTITUTION:The projection 1c of a grooved plate 1 is pressed to be fit into the recess 3b of a grooved plate 3, and the projection 3c of the grooved plate 3 is pressed to be fit into the recess 5b of a support plate 5, and then the projection 5c of the support plate 5 is pressed to be inserted into the through hole 7d of a support plate 7. Then the grooved plates 1, 3 and the support plates 5, 7 are stuck together so as to form a groove where a lap is stored, and a rotary lap is pressed to be inserted into the groove. Consequently, a rotary scroll and a fixed scroll can be joined together without heating, so that a scroll without heat deformation can be secured. Also, when oil is adopted as a lubricant, as the oil gathers within a recess 1b, the effect of lubrication can be improved.

摘要： PURPOSE:To easily and rapidly determine copper peroxide (Cu ) by decomposing a sample to be analyzed with an inorg. acid added with an Fe ion soln. and titrating the unreacted Fe ions in the resultant sample soln. with a standard oxidation soln. CONSTITUTION:Gaseous N2 is fed from an inert gas supplying device 3 into a analyzing vessel 1 to replace the air with the gaseous N2. This supply is continued until the titration ends. A prescribed amt. of the ground analysis sample is then weighed into the vessel 1. The standard Fe ion liquid and the inorg. acid are then added thereto and the soln. is heated to at least >=30 deg.C on a hot plate 2 which is a heat source to decompose the oxide superconductor. Then, part of the instantaneously dissolved Cu ions react with the Fe ions to form Cu . The unreacted Fe ion remaining in the resultant sample soln. are thereafter titrated with the standard oxidizing liquid, by which the copper peroxide (Cu ) in the oxide superconductor is determined.

摘要： PURPOSE:To improve accuracy in sensitiveness of a fluorescent X-ray analysis by providing a removable filter made of a material whose atomic number is smaller than an anode material or a compound whose constituent's average atomic number is smaller than the same. CONSTITUTION:When X-rays (continuous X-ray and characteristic X-ray of a target 2 material) generated when an anode (target) 2 is irradiated with an electron ray passes through a Be aperture 3 and a filter 4, the most parts are absorbed by the material of the filter 4, and then the characteristic X-ray of the constituent element is generated. In this case the characteristic X-ray effectively energize the filter material 4 to give a strong characteristic X-ray by using, as the constituent of the filter 4, a proper element whose atomic number is smaller than that of the target member 2. It is thus possible to obtain an improved excitation condition easily in a fluorescent X-ray analysis, and to improve the accuracy in sensitiveness of the analysis.
