  • Patent number: 10553063
    Abstract: A coin validation device that is implemented in a coin handling machine which stores therein a deposited coin on a denomination-by-denomination basis and which pays out stored coin in response to a disbursement instruction, the coin validation device, includes: a carrier that carries the deposited coin in a horizontally-fallen state in one direction; and a discriminator that identifies authenticity and denominations of the coin carried in the one direction by the carrier. Further, the carrier carries a coin, which is discriminated as a counterfeit coin by the discriminator, in another direction opposite to the one direction.

  • Patent number: 5770631
    Abstract: A process is disclosed for the production of connected microgel particles. According to the process, starting microgel particles having particle sizes of 100-0.01 .mu.m and a particle size distribution whose standard deviation is not greater than 100% of a mean particle size of the starting microgel particles are dispersed in a matrix component. The starting microgel particles are soaked with a monomer. The monomer is then polymerized, whereby the starting microgels are connected together. Also disclosed is an article comprising a base material and a layer of such connected microgel particles formed on a surface of the base material.
