Title: Atomizing apparatus
Inventor: ISHIKAWA KATSUHIKO
IPC: B05B7/04
Filed: 1992-04-13
Abstract: PURPOSE:To finely granulate atomized particles and make them uniform with air at low pressure and in a low flow rate and provide a compact atomizing apparatus capable of regulating atomizing amount in a wide range. CONSTITUTION:An air jetting hole 13 to supply air for fine granulation is formed in the outer circumference of a liquid nozzle 5 and the down stream side of a liquid jetting hole 10 and at a prescribed position A of the jetting flow of the liquid jet out of the liquid letting out hole 10. Consequently, since air flow hits directly in right angle direction to the liquid film of the liquid jet flow which is jet out of the liquid jetting out hole 10 and slows down, the relative speeds of the gas and liquid become high. Also the air flow hits the liquid film in unstable conditions at the time immediately before it is disunited, the contact conditions of the air and the liquid become good and thus the air flow rate is lowered.

Title: Sliding elastic bearer for structure
Inventor: HISHIJIMA YASUHISA
IPC: E01D19/04
Filed: 1995-03-27
Abstract: PURPOSE: To prevent the deformation of an elastic shoe by placing an intermediate plate slidable to an upper shoe fixed onto the underside of an upper structure on the elastic shoe put on a lower shoe fixed onto a lower structure while mounting a means constraining the horizontal displacement of the intermediate plate with the movement of the upper structure. CONSTITUTION: When horizontal force F such as an earthquake works to a bridge girder 1, the bridge girder 1 is moved in the direction of a bridge shaft, and horizontal force also works to an intermediate plate 20 through frictional force between a stainless plate 8 and a Teflon plate 22. The plate 20 is engaged and constrained to a side block 14 at that time, thus preventing movement. The bridge girder 1 is moved horizontally by sliding between the plates 8, 22 against frictional force, thus obviating deformation due to shearing of a rubber shoe 17. Consequently, the rubber shoe 17 having no shearing key at low cost may also be used, and is miniaturized. Accordingly, cost can be reduced, and there is no shearing key, thus lowering the quantity of the bridge girder jacked up at the time of the exchange of the Teflon plate.
