Abstract: Of the components of an anti-friction bearing, the metallic components to be subjected to rolling friction or sliding friction, such as rolling elements, are coated with a multiplicity of metal layers by ion plating. The uppermost layer is made of soft metal with lubricating property. The solid solubility of the metal of each intermediate layer in each adjacent metal is higher than the solid solubility of the soft metal in the metal material of the component.

Abstract: A pattern generating system for use in electronic sewing machines. Output-oriented data relating to the amount of bight or feed for a stitch pattern and order instruction-oriented data relating to the order in which the output-oriented data is read out are stored in a static memory (ROM) separately in such a manner as to distinguish between the data relating to bight and the data relating to feed. The data relating to the address at which the respective head data on stitch patterns is stored is stored at specified addresses in the static memory addressed by selection instructions corresponding to the stitch patterns given as by a pattern selecting button unit. The static memory is connected to a microcomputer which performs a control operation such that it indexes the static memory, analyzes order instruction-oriented data and updates addresses or gives the output-oriented data to a drive unit which controls the amount and direction of bight and feed.

Abstract: A speed control apparatus for use with an electric sewing machine having a motor drive control device for controlling the drive of the motor. The apparatus comprises a sensing device which can be optionally touched by the operator of the sewing machine, and a sensing signal generating circuit adapted to generate a signal in response to an electric change which is caused when the human body touches the sensing device, the arrangement being such that in response to the operator of the sewing machine touching the sensing device, the sensing signal generating circuit gives a predetermined signal to the motor drive control device, thereby stopping the drive of the motor.

The bearing has improved dustproofness, leakproofness and rotation performance afforded by the seal assembly.
