Latest Patents

One of Takeda's latest patents is an "Automatic switching method of a right of management/control." This invention provides an automatic method for switching the management/control rights for a shared-storage unit among multiple service processors in a cluster-coupled system. The process involves registering the physical number of the service processor that acquires the management/control right and establishing a communication line among all service processors. When a first cluster detects a power-off or hang-up message, it determines a new physical number for the service processor based on a predetermined decision theory.

Another notable patent is the "Variable delay gate circuit." This invention pertains to a gate circuit device used in integrated circuit testers, allowing for the variable setting of signal propagation delay times. The device includes a gate circuit with emitter-coupled transistors and a constant current source transistor. It controls the signal propagation delay time by regulating either voltage or current in response to a control current, thereby enhancing the testing capabilities of various integrated circuits.
