Latest Patents

One of his latest patents is a "System for generating stitch pattern signals for electronic sewing." This system includes a read-only memory that stores output data related to the stitching movement of the needle for various stitch patterns. It also features order instructing data that specifies the sequence in which the output data is to be read. The system is designed to alternate the stitching and feeding timings in relation to the machine's main shaft, allowing for the repeated reading of stored data to form symmetric stitch patterns.

Another significant patent is the "Pattern generating system for use in electronic sewing machines." This system stores output-oriented data regarding the amount of bight or feed for a stitch pattern in a static memory. The data is organized to distinguish between bight and feed information, and it is connected to a microcomputer that controls the indexing and output of the data to a drive unit. This innovative design allows for the exchange of static memory with different stitch pattern data.
