Title: Cylindrical vibration isolating mount
Inventor: NAGAI HIROAKI
IPC: B60G7/02
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To stabilize the vibration isolating performance while preventing a remarkable rise of a dynamic spring constant even in the case of a different initial load by providing an inner diameter dimension changing part at axial intermediate part of an outer cylinder member, and setting a large inner diameter dimension at a tip of the outer cylinder member in a direction of the movement of a shaft member due to the initial load. SOLUTION: An initial load P due to a dead weight of a body is applied in the axial direction between an inner and an outer cylindrical metals 12, 14. The inner cylindrical metal 12 is relatively displaced downward in the axial direction in relation to the outer cylindrical metal 14. A main body rubber elasticity 15 is relatively displaced downward in the axial direction in relation to the outer cylindrical metal 14 from a small diameter cylindrical part 30 of the outer cylindrical metal 14 to an intermediate tapered cylindrical part 28 formed with a distance between opposite surfaces of the inner and the outer cylindrical metals 12, 14 in the radial direction larger than that of the small diameter cylindrical part 30, and furthermore, toward a large diameter cylindrical part 32.  As a result, a remarkable change such as a rise of a static spring coefficient and a dynamic spring coefficient of the main body rubber elasticity 15 with the input of an axial load is reduced or avoided, and the vibration isolating performance is stabilized even in the condition that the initial load is input and a different initial load is input.

Title: Melting device and melting method
Inventor: HASHIDA SHIGEO
IPC: F27B1/08
Filed: 1988-09-30
Abstract: PURPOSE:To reduce and melt minute grains of oxides such as iron sand to obtain the highly pure cast iron and facilitate the adjustment of the composition of carbon content by disposing an electromagnetic coil around the external surface of the furnace wall to subject a heater to electromagnetic induction heating. CONSTITUTION:The furnace body 1 is lined with ceramic refractory material, and the power having an intermediate frequency range is applied to an electromagnetic coil 2. Lumps 4 of black lead which is electrically conductive and refractory are induction-heated by the electromagnetic coil 2. The material 5 is melted by the radiation heat from the black lead lumps 4 and a small quantity of high-temperature gas which is generated by the reduction of the oxides, and is heated and reduced as it drops through the gaps between the black lead lumps 4 to be discharged from the outlet 3. Even if the material 5 is in the form of powder which can not normally be used or if it has been oxidized, it can be efficiently melted. When the grain size of the material 5 is suitable for the induction heating, the material itself generates heat due to the electromagnetic induction, resulting in the efficient melting. Since the preheating range of material is short, the time between the feeding of material and the discharge of molten metal also becomes short, and the adjustment of the contents can be facilitated.

Abstract: PURPOSE:To increase the dust collection amount per unit volume, by applying charge to the dust in dust-containing gas in the upstream side of dielectric boddies using corona discharge and collecting dust on the surfaces of the dielectric bodies by the electric fields between the dielectric bodies. CONSTITUTION:When the voltage of a power source 7 is applied to an electric field applying electrode 4, an external electric field is applied to the whole of the dielectric bodies 5 between the electric field applying electrode 4 and an earth electrode 3.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to well control light transmittance over the entire part of an optical filter by providing the inside surface of a cell with >=1 projecting parts. SOLUTION: The plural granular projecting parts 7 are formed by sputtering, vapor deposition, etc., on the surfaces of a first ITO electrode 4 and second ITO electrode 5 formed on the main surface of a first transparent substrate 1. The surface-to-surface contact of the ITO electrodes 4, 5 and the second transparent substrate 2 is prevented by forming such projecting parts 7 even if the inside surfaces of the cell are brought near to each other by the deformation of the cell by an atm. pressure change or temp. change, etc., and the trouble, etc., at the time of assembly. Namely, the projecting parts 7 and the main surface of the second transparent substrate 2 come into point-to-point contact when the inside surfaces of the cell approach each other. The surface-to-surface contact of the ITO electrodes 4, 5 and the second transparent substrate 2 is thus prevented.  Such projecting parts 7 scatter the incident light from outside and attenuate the incident light from outside. Further, the surface areas of the electrode parts increases and, therefore, the light shieldability at the time of control of the light transmittance by this optical filter is improved.
