摘要:
This invention provides an improved deflection yoke of a self-convergence system for deflecting electron beams of a color CRT with in-line electron guns for emitting the electron beams, capable of preventing both a vertical misconvergence of R/B lines and a cross-misconvergence at a low cost. The deflection yoke includes at least a pair of saddle type horizontal deflection coils. Each of the saddle type horizontal coils has two main coil sections divided by a window at a center thereof, a front rim forming a front mouth, a rear rim forming a rear mouth and, at least, a first split-winding section nearby one of the front and rear rims. Further, a second split-winding section is provided in the respective two main coil sections in a rear half of the respective two main coil sections. The second split-winding section is divided into two parts, a first coil part positioned close to the window and a second coil part positioned remote from the window, by a small opening. The first coil part has a bent part being bent toward the window to define the small opening.

A heat exchanger fin according to the invention has a multiplicity of fins arranged substantially in parallel with the direction of air flow and at least one heat transfer tube to which said fins are connected in a heat conducting relation. A multiplicity of louvers inclined by a small angle to the direction of air flow are formed in said fins.According to this construction, it is possible that the air as a whole can flow substantially straight across the heat exchanger and can strongly collide with all louvers, thereby to ensure a reduced flow resistance encountered by the air flow, as well as improved heat transfer performance of the heat exchanger.

In an anti-vibration device having a partition member dividing a fluid-sealed chamber into upside and downside, aimed at enhancing the anti-vibration performance by preventing unwanted leak of the fluid through through-holes of the partition member. To that end, the partition member is constructed of an elastic membrane partitioning the fluid-sealed chamber, and a pair of grids limiting displacements of the elastic membrane; and the elastic membrane is provided at its either surface with projecting streaks integral therewith, the projecting streaks surrounding through-holes, defined by the grids, over their whole peripheries and abutting on the grids, thereby regulating the flow of fluid among adjacent through-holes.

In a heat transfer tube for a zeotropic refrigerant mixture, the inner surface of the tube in which the zeotropic refrigerant mixture flows is formed with grooves having cross portions where the grooves intersect with each other, or the inner surface of the tube is formed with a plurality of independent projections. Thus, concentration boundary layers generated in the zeotropic refrigerant mixture are stirred to reduce the thickness of the concentration boundary layers, thereby decreasing the diffusion resistance and promoting the stirring effect. Consequently, there can be provided a heat transfer tube for a zeotropic refrigerant mixture which exhibits a high heat transfer performance, and a heat exchanger of a cross-fin tube type, a refrigerator and an air conditioner which include such heat transfer tubes.

A propylene polymer is excellent in rigidity, heat resistance, surface hardness, glossiness, transparency and impact resistance. A propylene copolymer (wherein the amount of monomer units derived from an .alpha.-olefin other than propylene is not more than 5% by mol) is excellent in transparency, rigidity, surface hardness, heat resistance, heat-sealing property, anti-blocking property, anti-bleedout property and impact strength. A propylene copolymer (wherein the amount of monomer units derived from an .alpha.-olefin other than propylene is not less than 5% by mol) is excellent in transparency, environmental aging property, and effective in improving heat-sealing property at low temperature and impact strength. A propylene elastomer is excellent in heat resistance, impact absorbing capacity, transparency, heat-sealing properties and anti-blocking properties.
