IPC: H01L21/66
Filed: 1989-03-23
Abstract: PURPOSE:To accurately measure an impurity concentration and the like in an impurity region to be analyzed without being influenced by an impurity region in a circumference by a method wherein, while the impurity region to be analyzed directly under a protective film is being eliminated one after another by primary ions, a concentration and the like of a substance contained in the impurity region to be analyzed are measured. CONSTITUTION:The surface of an impurity region 13 to be analyzed in the central part other than an impurity region 12 in a circumference of a semiconductor substrate 11 is covered with a protective film 14a. When primary ions 15 are radiated in this state, the protective film 14a and the impurity region 12 in the circumference are eliminated by an ion sputtering operation. When the primary ions are radiated in succession, a residue of the protective film 14b is removed and the impurity region 13 in the center as a region to be analyzed is started to be eliminated. At this time, a value amount of secondary ions in an impurity substance emitted from the surface of a specimen is analyzed; an impurity concentration in the impurity region 13 in the center and its depth are measured. Thereby, it is possible to accurately measure a concentration or the like in the impurity region to be analyzed without being influenced by the region in the circumference.

Title: Cylinder draw die and its forming method
Inventor: OOSAWA SHIGERU
IPC: B21D22/26
Filed: 1981-05-15
Abstract: PURPOSE:To resolve the interference between the recess part of a cylinder and a ring, which is fitted to a draw die holder, and to improve the precision of working, by shaping the recess part and a projecting part of the cylinder in the upper  part and the lower part of the ring respectively. CONSTITUTION:When a round work W1 is set on a ring 12 and an upper die 13 is pressed downward, the outside circumferential edge is formed to a cylindrical shape in a circumferetial taper part C higher than the center of the ring 12, and simultaneously, a recess part is formed by a shaping projecting part B projecting toward the inside. When the upper die 13 is pressed downward furthermore, the outside circumferential edge of the cylinder forms a projecting part in a part A from the taper part C to the lower part of the ring 12. At this time, since each recess part of the cylinder formed by the shaping projecting part B is moved from the center of the ring 12 to the lower part and reaches the part, where the diameter of the ring is expanded, from a slope part B1, each shaped recess part of the cylinder does not interfere in the ring 12 itself.

Abstract: PURPOSE:To attain small size and low cost of the equipment by providing a comparison section comparing a read data of an actuator varied with an original carried to a read position with a preceding data and detecting the tip of the original from a change in the read data. CONSTITUTION:An actuator 10 is provided freely turnably this side of a slit 7, pressed by an original 3 carried to a read position 6 and part of the actuator appears on the slit 7. Then the actuator 10 appearing on the slit 7 is read by a read sensor 9 similarly as the original 3 and the read data is sent to a comparison section 11. The comparison section 11 compares the read data from the read sensor 9 with the preceding data and detects the tip of the original 3 from the change in the read data. Thus, since the tip of the original 3 is detected without providing any sensor on an original running path 5, the size of the equipment is reduced and the cost is reduced.

IPC: B24B13/00
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To shorten a machining time and reduce the occurrence of wear of a grinding wheel by a method wherein a grinding wheel spindle part and a work spindle part are arranged, a work slide table part is moved in parallel to the rotary shaft of a work spindle part, and a work is pressed against a form grinding wheel to form the work in an aspherical shape. SOLUTION: When aspherical machining is applied on a glass lens, a work 19 is first fixed at a work chuck part 23. Meanwhile, a form grinding wheel 39 on which a grinding wheel surface having a shape conforming to that of a glass lens is formed is locked at a grinding wheel spindle part 41 by means of a screw. The mounting angle of the work 19 is regulated by rotation of a work tilt table part 27 and a relation to a contact surface between the form grinding wheel 39 and the work 19 is regulated through movement of a grinding wheel shift table part 45.  After a work spindle part 25 and the grinding wheel spindle part 41 are rotated, machining is effected by moving a work slide table part 29 during a time starting from a machining origin at which processing resistance begins to be detected by a processing resistance detecting part 47 and ending in a processing set value set by a control part 15.

Abstract: PURPOSE:To improve temperature efficiency and obtain the heat exchanger having no biased flow of fluid in two-phase flow by a method wherein a plurality of fin members, having plural pieces of long holes, and a plurality of spacer members, having two pieces of holes, are laminated alternately and the holes of both members are communicated to form the flow path of heat exchanging fluids. CONSTITUTION:The fin member 10 is provided with long holes 11 with a space in the direction of flow of the other heat exchanging fluid upon laminating it while the spacer member 12 is provided with a pair of holes 13 with a space shorter than the length of the long holes provided on the fin member 10. The fin member 10 and the spacer member 12 are laminated so that the long holes 11 of the member 10 are communicated with the holes 13 of the member 12 and the communication can be isolated from the outside thereof while the holes 13 and a part of the long holes 11 forms headers 14, 15. Fluid A flows into the heat exchanger from the header 14 at the outlet side of the fluid B, is distributed into the long holes 11 and is collected into the header 15 to flow it out. In this case, the fluid A exchanges it's heat with the other fluid B in the condition of counter-flow since the long holes 11 become the principal heat exchanging section. Accordingly, the temperature efficiency may be improved and there may be no biased flow of two-phase fluid.

Abstract: PURPOSE: To enhance turbine efficiency by computing the diameter of a turbine rotor and a casing in steady state based on the measured values of operation conditions of a gas turbine engine and computing the desired clearance between the rotor and casing based on the engine speed. CONSTITUTION: A turbo-fan aircraft engine combusts fuel in a combustor 12 with supply of compressed air compressed by a booster compressor 6 and a high pressure compressor 9, drives a high pressure turbine 15 with the high pressure gas generated thereby, and rotates the high pressure compressor 9 connected thereto.
