Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To correctly measure an object without interfering with the object, by positioning a diameter-measuring head at a center coordinate of a hole of the object which is obtained by a touch signal probe. SOLUTION: A touch signal probe 51 is set at a leading end of an arm 28 of a main body 21 of a measuring apparatus. While the main body 21 is moved in three dimensional directions, the probe 51 is inserted to a hole to be measured of an object W into touch with three points of the hole. The probe 51 outputs a touch signal when coming into touch with the hole. A coordinate value in each axial direction is read and, a center coordinate and a diameter of the hole are operated from coordinate values of the three points. Thereafter, an inner diameter-measuring head corresponding to the obtained diameter among inner diameter-measuring heads 61-63 is selected and fitted at the leading end of the arm 28. The main body 21 is moved again in three dimensional directions, and the selected and fitted measuring head is moved to the center coordinate of the hole to be measured.  After the inner diameter-measuring head is inserted into the hole to be measured, a pair of measuring elements are moved to be separated from each other and brought in touch with an inner wall of the hole. A distance of the measuring elements is measured by a measuring means, from which an inner diameter of the hole is obtained.

IPC: G01J9/00
Filed: 1990-09-25
Abstract: PURPOSE:To improve wavelength measuring precision and simplify a device by using a Cerenkov radiation type secondary higher harmonic generating element. CONSTITUTION:The light L1 from a light source 3 is entered to the light waveguide pass 2 of a Cerenkov radiation type SHG element 1 through a collimator lens 4 and a condenser lens. Thus, a secondary higher harmonic is generated by the non-linear optical effect of the SHG element 1, and the secondary higher harmonic L2 is emitted with a Cerenkov radiating angle theta from the main surface of a non-linear optical material 11. The incident light or primary light is cut by a filter 7, and only the secondary higher harmonic L2 is passed through it and entered to a position sensor 8 consisting of CCD, whereby the incident position is detected. The Cerenkov radiating angle theta can be detected from this position, and the input wavelength depending on the radiating angle can be precisely measured.

Title: Laser beam machine
Inventor: SAKURAI KAZUO
IPC: B23K26/14
Filed: 1984-12-04
Abstract: PURPOSE:To disuse the setting of the changing time of each working conditions and to shorten the machining time of a start hole by providing the pressure sensor of the assist gas inside a work head and by changing the laser beam continuously from the pulse based on the signal thereof. CONSTITUTION:The CO2 laser beam irradiated from a laser emitter is condensed on the upper face of the body 6 to be machined by a condenser lens 11 mounted in a machining head and the assist gas led from an assist gas inlet port 15 is sprayed to the body 6 to be machined via a tip nozzle 14. The pressure of the assist gas of the inside of the machining head is constant due to the gas between the body 6 to be machined and the tip nozzle 14 and the bore diameter of the tip nozzle 14 being constant at the work starting time. The assist gas pressure inside the machining head is reduced due to the assist gas being passed through a start hole 24 when it is penetrated on the body 6 to be machined by the CO2 beam of the pulse. The change in this pressure is detected by a pressure sensor 22. The signal is transmitted to a control device 7, the CO2 laser is changed from the pulse to continuation and a usual work is started.

Title: Method for processing particles using thermally fusible substance
Inventor: SAKAMOTO HIROSHI
IPC: B29B9/16
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent the adhesion to the wall or the flocculation of particles from occurring and thereby improve the yield and the uniformity of the content by loading third particles when the particles are processed like granulation or the like by making first particles adhere to each other or flocculating the first particles. SOLUTION: Raw material powder (first particles) intended for particle processing and a low melt-point substance (second particle) serving as a binder, are loaded in a container 1 simultaneously or sequentially. Further the first particles are processed by making the first particles adhere to each other and flocculating these particles with the molten or softened second particles. Further, the second particles are solidified by cooling through adding the third particles. The adhesion to the wall face and the mutual adhesion and flocculation of the particles are prevented from occurring by adding the third particles as the surface of the melt of the second particles being a factor for the adhesion is covered by the third particles.  The surface of the particles is solidified by cooling because the surface temperature of the particles in the container 1 is rapidly lowered by the heat capacity of the third particles well ahead of the wall surface temperature.

Abstract: PURPOSE:To readily collate a picture sheet with a picture receiving sheet by providing a supporting means which supports the ends of the picture sheet and picture receiving sheet on the upper part of a placing table tilting within a range of prescribed angles and which collates the picture sheet with the picture receiving sheet. CONSTITUTION:The picture receiving sheet 16 is supported on the placing table 12 by the supporting means 22, and placed thereon.

Abstract: PURPOSE:To prevent the breakage of the connection between a focus spring supporting member and a base by sticking a balancing weight member having the weight almost equal to that of a lens group, etc., to the supporting member. CONSTITUTION:The balancing weight member 8 having the weight almost equal to that of the lens group 1, focus spring 2, etc., is confronted with the member 4 for supporting and fixing the lens group 1 and focus spring 2 to balance with the weight of the lens group, etc. Accordingly, the rapid sectorial rotation due to tracking correction with the shaft as an axis and the vertical vibration of the lens group due to the focus correction have no effects on the member 4, and the tracking and focus are surely corrected. Consequently, the breakage of the focus spring supporting member is effectively prevented with this simple constitution.
