Title: Fluid sealing vibrationproofing unit
Inventor: YODA NORIO
IPC: F16M7/00
Filed: 1989-03-18
Abstract: PURPOSE:To increase a loss factor in a low-frequency region for a vibrationproofing unit having a first orifice structure partitioned by first and second liquid chambers by arranging a second orifice structure by which a flow rate in a circular orifice of the first orifice structure is controlled according to the size of a certain orifice diameter length maintained, in the first liquid chamber. CONSTITUTION:When low-frequency vibration of large amplitude is applied between first and second substrates 1, 3, difference in liquid operation is caused between first and second liquid chambers 21, 23, whereby a first orifice structure 11 is fluctuated due to the deformation of a third elastic body 20, and a liquid flow rate in a circular orifice 15 is increased due to a contracted vein effect of an orifice 35d of large diameter in second orifice structure 35, and liquid flows drastically, the liquid in the circular orifice 15 being defined as a primary mass. The low-frequency vibration of large amplitude can thus be absorbed. By varying the length of diameter L of the orifice 35d, resonance frequency of the vibration input between the substrates 1 and 3 can be varied.

Title: Method for fixing light-irradiated image deposited on glass surface
Inventor: MARUNO SHIGEO
IPC: G03C5/56
Filed: 1981-05-06
Abstract: PURPOSE:To obtain a light recording material capable of repeating regeneration and erasion, by irradiating the surface of a Ge-S type glass containing a specified proportion of Ge, and silver with light in order to deposit a thin metallic film onto the surface, and fixing the light-irradiated image on the irradiated part. CONSTITUTION:A glass plate containing 17-30atomic %, and silver in addition is sealed  in a transparent sealed tube evacuated to <=10<-3>mm.Hg, for example, so as to give Ge22S45Ag33, melted in a melting furnace heated to 800-1,000 deg.C for about 8hr and stirred. A block of glass quenched in water is taken out, sliced to about 3mm. width, the surface is mirror polished, and a plate 5 for use in image irradiation is thus obtained. The plate 5 is exposed to light emitted from a high-pressure mercury arc lamp, converged with a lens system 2, and passed through a thermal ray cut filter 3 and, for example, a circular mask pattern 4 to form the silver image 2 of the pattern 4 on the surface 1 of the plate 5 as shown in the figure. When the image 2 is irradiated with the light more intense than said light, the silver diffuses into the inner part of the glass and disappears. When the plate 5 is covered with 50-30nm thick gold or the like, the image 2 is fixed so as not to disappear. Since the thickness of silver of the image 2 is about 300nm, the plate 5 can be reused by polishing and removing it.
