摘要:
A device which reduces beat distortion caused by crosstalk between subchannel signals in a multichannel sound system. To effect reduced beat distortion, one component present in both the sum and difference subchannel is attenuated before the subchannels are modulated.

An optical record disc is provided having a guide signal pit previously formed on a base plate for reading out a tracking information by a laser beam. A reflection film is coated on the base plate including the guide signal pit portion, and the record blank portion. A record layer of a removing type is formed over the reflection film. The record layer has a uniform thickness over the record layer and a uniform thickness, of substantially smaller dimension over the guide signal pit portion.
摘要:
An object of the present invention is to provide a method for producing a resin-coated sliding member wherein the method ensures the productivity and at the same time enables the recycling of the solvent so as to be friendly to the environment. According to the present invention, included are a coating step in which a porous sintered layer prepared by sintering on a back metal is impregnated with a solvent-containing resin composition, a heating step to heat the solvent and the resin composition and a collecting step to collect the solvent wherein the vaporized solvent is sucked, liquefied and collected; and hence even when a solvent having a high boiling point and a low vapor pressure is used, the solvent can be collected efficiently by applying a low energy, and the collected solvent is recycled so as to be friendly to the environment and to enable the reduction of the consumed raw materials.

The present invention provides a method for producing a resin-coated sliding member in which problems such as blistering do not occur even if drying of the solvent is carried out rapidly, and in which quality is also stabilized. The method includes an impregnating step for impregnating a solvent-containing resin composition by a resin impregnating apparatus 12 into a porous sintered layer sintered on a back metal 11, a drying step for drying with a drying furnace 13 the solvent in the resin composition impregnated in the porous sintered layer using an electromagnetic wave oscillator which radiates electromagnetic waves in a wavelength region which is easily absorbed in the solvent, and a baking step for baking with a baking furnace 14 the resin composition impregnated in the porous sintered layer.
