Latest Patents

One of Tomikawa's latest patents is the "Terminal Crimped State Testing Method." This innovative method involves creating a reference waveform based on a load when a terminal is in a good crimped state. The reference waveform is divided into multiple segments to identify singular points, which are then integrated. A characteristic waveform is generated for the crimping terminal being tested, and the integrated values of the reference waveform segments are compared with those of the sample waveform segments. This process allows for stable testing of the terminal crimped state, precise defect detection, and reduced testing time.

Another significant patent is the "Method of Testing a Wire Harness Using a Multicontact Connector." This method features a connector with a first portion that varies according to the type of connector. A multicontact switch pin is fixedly arranged on a carriage base, allowing the probe pin to engage with the first portion. The continuity of the test circuits is checked to determine the position of the first portion, ensuring accurate testing of wire harnesses.
