Abstract: An integrated controller for motion control and motor control comprises a first processor, a second processor, a cache and a shared memory. The first processor is configured to run an operating system and at least perform motion control. The second processor is configured to at least perform motor control and normally not run the operating system. The cache is coupled to the first processor and the second processor. The shared memory maps onto the cache. The first processor and the second processor are configured to share the shared memory and accordingly perform data transmission via the cache during the periods of motion control and motor control. The first processor, the second processor and the cache are integrated in a same chip.

Abstract: Provided are an electrocatalyst for a fuel cell having a large amount of catalyst metal particles supported on a carbon support and maintaining a high-dispersity state and a method of preparing the same. The electrocatalyst is characterized by being composed of catalyst metal particles having a secondary structure composed of at least one kind of primary metal particles having a particle diameter of 0.1 to 1.5 nm, or the catalyst metal particles having a core-shell structure of which the core is composed of metal particles having a particle diameter of 2.0 nm or less, and carbon particles. The method of preparing the electrocatalyst, including a first loading step for producing the core of catalyst metal particles wherein distances between the particles are controlled to 2.0 nm or less on a support and a second loading step for growing the catalyst metal particles, enables the amount of metal loaded on the support to increase without causing aggregation of the catalyst metal particles in the end.
