Latest Patents

Kanbara’s listed patents include two automatic analyzer inventions.

“Automatic Analyzer and Rack Transfer Device” describes a system for moving specimen-holding racks to one or more analysis units. A rotating rack standby disk holds multiple waiting racks, while a dedicated reciprocating transfer line connects each analysis unit to the disk. The system transfers one rack at a time and returns it to the disk after specimen sampling and processing, providing a consistent approach as the number of analysis units changes.

“Automatic Analyzer” concerns ultrasonic agitation of samples and reagents in a reaction container. A piezoelectric transducer generates the ultrasonic waves, and a power supply applies a voltage frequency-modulated across a selected range. The analyzer then measures the reaction product and analyzes sample components. The described design aims to simplify adjustment of the agitation system and support reliable results despite differences in the frequency characteristics of ultrasonic-wave generators.
