Company patents
CKD CORPORATION
CKD CORPORATION's patent strategy reveals a surprising shift away from several core manufacturing areas, with Packaging Machines seeing a 100.0% decline in 2026 so far and Welding & Soldering also dropping 100.0% in the same period. While 'Valves' remains their largest category at 33.0% of their portfolio, the significant 100.0% year-over-year growth in 'Material & Chemical Analysis' in 2024 suggests an emerging focus on materials science, despite a subsequent decline in 2025 and 2026.

Valves specifically designed for managing fluid power in hydraulic or pneumatic systems, including components for pressure regulation, flow direction, and system centering.
Integration of inspection apparatuses and digital printing units directly into packaging machines to monitor quality, apply information, or decorate packages during the continuous packaging process.
Systems that employ imaging and image processing to automatically detect defects, verify states, or ensure quality control in manufactured goods, printed materials, or industrial processes.
Specialized valve designs for domestic and commercial applications involving water distribution, temperature control, and air conditioning, often focusing on integration, materials, and specific flow characteristics.
Technologies and methods for securely closing, sealing, and maintaining the integrity of packages, including heat sealing, vacuum sealing, strapping, and specialized closure units, often involving material interaction and atmosphere control.
Methods and apparatuses for creating unique package structures, such as recesses in specific materials, blister packages, or single-dose units, and for controlled dispensing of products from storage into these containers.
Techniques and systems for measuring three-dimensional shapes, depths, or surface profiles using optical principles, including diffraction, interferometry, structured light, and imaging.
Incorporating sensors and processing capabilities directly into valve systems to monitor operational state, detect malfunctions, measure flow parameters, or verify proper installation.
Valves engineered to automatically open or close based on pressure differentials, preventing over-pressurization, controlling flow direction, or suppressing backflow in fluid systems.
Technologies for non-contact measurement of distance, position, or 3D properties of a target object, often involving active emission and detection of light or radio frequency waves, including target tracking.
Mechanisms allowing rapid, secure, and often sealed attachment and detachment of pipes, tubes, or hoses, frequently featuring locking, sealing, and release components for efficient assembly and maintenance.
Couplings and fittings designed for specific fluid properties (e.g., cryogenic, chemical, medical, high-pressure) or requiring aseptic conditions, low-spill characteristics, or antimicrobial features to ensure safety and integrity.
Manufacturing processes and material compositions for creating electronic circuits on flexible or conformable substrates, enabling novel form factors, enhanced durability, and new applications beyond rigid PCBs.
Systems and methods for automated substrate transport, precise positioning, temperature regulation, and chamber environment management to ensure process stability, uniformity, and yield in semiconductor manufacturing.
Tubes, hoses, or ducts incorporating additional components or features beyond simple fluid conveyance, such as embedded electronics (sensors, heaters), structural reinforcement, or segregated compartments for cable routing.
Systems and methods for accurately measuring and compensating for position, orientation, and movement errors in mechanical systems, often for manufacturing, robotics, or optical alignment.
Techniques for precise material removal, pattern shaping, and controlling etch selectivity or uniformity, often involving plasma, wet chemistry, or directed beams to achieve desired features on semiconductor substrates.
Systems and methods for repairing, reinforcing, or isolating existing pipes, often involving internal lining, curing processes, or sealing techniques without extensive excavation or replacement.
Design and features of welding and soldering tools, fixtures, and accessories that enhance user safety, ergonomics, operational efficiency, and precise workpiece manipulation, including protective equipment and clamping mechanisms.
