Title: High elasticity and low thermal expansion aluminum powdery alloy excellent in corrosion resistance
Inventor: HAYASHI MINORU
IPC: C22C21/02
Filed: 1992-05-19
Abstract: PURPOSE:To obtain an aluminum powdery alloy excellent in corrosion resistance and having high elasticity and low thermal expansion by constituting it in such a manner that it contains a specified amt. of Si, and the balance inevitable impurities. CONSTITUTION:Aluminum allay powder is constituted in such a manner that it has a chemical compsn. contg., by weight, 15 to 25% Si, and the balance Al with inevitable impurities. Si improves its rigidity and shows a remarkable effect on the deterioration in its thermal expansion coefficient, but, for obtaining >=8000kg/mm<2> rigidity and <=20X10<-6> deg.C<-1> thermal expansion coefficient, the addition of Si by >=15% is required, and furthermore, in the case of >25%, its formability and workability deteriorate though the rigidity improves and the thermal expansion deteriorates. In this way, the objective aluminum powdery allay excellent in corrosion resistance suitable as the driving parts of precision mechanical equipment as well as having high elasticity and low thermal expansion can be obtd.

Title: Vibration damping device
Inventor: IIYAMA FUMIYA
IPC: F16L3/215
Filed: 1993-05-31
Abstract: PURPOSE:To damp vibration due to an earthquake and others while allowing slow displacement against a support body of a damping object of a piping and others in which a hot temperature fluid flows. CONSTITUTION:A damper 1 and an oscillation absorber 12 are directly connected to each other on the same axial line. The damper 1 allows slow displacement due to temperature change of a piping and others but constrains sudden displacement due to oscillation of an earthquake and others. The oscillation absorber 12 is constituted so that a piston rod 16 moves to get in and out of a cylinder 13 and a rod cover 18. A visco-elastic member 19 is adhered between the piston rod 16 and a support plate 20 and fixed on the cylinder 13 and the rod cover 18. The visco-elastic member 19 has a characteristic to change a load at the time when the piston rod 16 and the rod cover 18 are relatively displaced along a hysteresis curved line against displacement. Consequently, oscillation of the earthquake and others becomes reciprocal motion against the rod cover 18 of the piston rod 16 by the damper 1, and the visco-elastic member 19 damps vibration.

IPC: H01S3/032
Filed: 1980-10-31
Abstract: PURPOSE:To make a laser beam mode uniform and stabilize laser output by a method wherein an aperture which has a diameter corresponding to that of the required laser beam is formed by fabricating a free end of a thin tube of a double composition gas laser tube. CONSTITUTION:An aperture 12c for regulating a mode is formed by fabricating a free end of a thin tube 12. The diameter of the aperture 12c is approximately 1.7- 2.0 times that of a laser beam and its center is consistent with a center axis of the thin tube 12. The free end of the thin tube 12 is previously melted symmetrically with respect to the center axis of the tube 12, so that it has a shape of the reduced aperture. Then the melted free end is ground from the end until it is fabricated to have the required diameter. With above method a discrepancy of the optical axis is eliminated, so that the uniformity of the laser beam mode can be obtained.
