  • Patent number: 6367101
    Abstract: This invention provides an automatic hair washer that is capable of preventing the hairs of the person under hair washing from being attached to the internal wall of the cistern as well as the hairs of the person under hair washing being tangled with each other during the hair washing. By providing a hair receiver having an arch-shaped or ring-shaped hair receiving part, which collects and hangs the hair of the person under hair washing, it is possible to prevent the hair of the person under hair washing from being attached to the internal wall of the sink. Since they are collected by the hair receiver, the tangling of the hair of the person under hair washing by the showers spouted during the hair washing can be prevented.

  • Patent number: 6364517
    Abstract: A device which can reduce the workload on operators during replenishment and stocktaking of drugs stored in a drug dispenser. The drug dispenser has a memory for storing data on the initial number of drugs in each of the drug feeders, a processor for calculating the number of drugs currently remaining in each drug feeder by subtracting the number of drugs discharged from each feeder from the initial number of drugs in each drug feeder, and a display for displaying the name of drugs if the number of drugs currently remaining in any drug feeder is smaller than a predetermined value. With this arrangement, an operator can easily see which drug feeders are short of drugs without directly checking the respective feeders by removing them from shelves. The workload on operators for drug replenishment is thus reduced.
