Title: Method for measuring amount of solder
Inventor: ITO TOSHIHIDE
IPC: G01F17/00
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method in which the amount of spare solder can be measured precisely and simply by a method wherein the radius of curvature of the surface of the solder is found on the basis of the time difference in the detection of reflected light between a plurality of light-receiving elements installed at constant intervals in the reflection direction of laser light and a solder volume is approximately calculated on the basis of the radius of curvature and on the basis of the width and the length of a pad. SOLUTION: An optical system which comprises respective light-receiving elements 6, 7, 9 is fixed in a height of, e.g. 5 to 20 mm from a measuring face, and the elements are arranged at an interval of about 10 to 40 mm in a scanning direction. Laser light which is radiated from a laser light source 3 is condensed by a condensing lens system 4, it is passed through a route 11, the measuring face of cylindrical spare solder 13 is irradiated, and the light is reflected to a direction according to the inclination of the surface of the spare solder 13 in an irradiation point. Then, since the direction of the reflected laser light is changed according to the movement of a scanning line, it is detected by the respective light-receiving elements 6, 7, 9 only when it is reflected in a specific direction.  In a computing part, the time difference in a detection between the respective light-receiving elements 6, 7, 9 is computed, and the radius of curvature of the surface of the spare solder 13 is computed on the basis of a sweep speed. The volume of the spare solder 13 is found on the basis of the width, the length and the height, of a pad, which are found in advance.

IPC: G01N37/00
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a scanning probe microscope in which it is not required to maintain a viscoelastic substance in a semihardened state and whose resolution can be enhanced. SOLUTION: A Z-axis coarse adjusting operation which brings a probe 10 close to a region on the surface of a sample 32 on which an atomic force acts is finished. Then, a current which flows to a heating coil 16 is cut off, and a viscoelastic substance 17 is cooled spontaneously. A scanner is thermally contracted by its spontaneous cooling. However, the fine adjustment control of the scanner is maintained in a neutral state (a state that a current flowing to a voice coil 6 is zero). A voltage which corresponds to a control signal from a PI control part 43 is supplied, from a power-supply-voltage control part 44, to a sample-height adjusting device 34 which is constituted of a laminated piezoelectric ceramic or the like. The height of the sample-height adjusting device 34 is controlled in such a way that the distance between the probe 10 and the sample 32 becomes always constant.  The time elapses, a thermal equilibrium state is reached, and the contraction of the length of the scanner is stopped. Then, the sample-height adjusting device 34 is fixed so as to be changed over to the fine adjustment control of the scanner.

Title: H-steel pile cutting method
Inventor: YAMADA TAKESHI
IPC: B24C5/02
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of an extreme fluctuation in a cutting speed during cutting of an H-steel pile by a water jet. SOLUTION: A water jet 7 is injected, as shown by (a), at an inclination angle θ against the web 2 of an H-steel pile 1 to effect cutting of the H-steel pile 1. A water jet nozzle 6 is moved in a cutting direction 8 to cutting positions p1-p4. Since the web 2 is cut, as shown at (b), in a direction approximately equal to a longitudinal direction up to cutting positions p2-p3, a substantially cut thickness is increased and a cutting speed is lowered. By setting the inclination angle θ to 15 deg. or more, the apparent increase of the thickness is suppressed to 3.9 or less times. As shown at (c), when the inclination angle θ is set to 0, a cutting speed is extremely lowered in the vicinity of a cut position p13 where the web 2 is cut, and setting of a cutting condition is extremely difficult to make.
