Ultrasonic Bath: Automatic Washing Machine for Human From 1970

At the 1970 World Expo in Osaka, consumer electronics maker Sanyo demonstrated their vision for the future by showcasing a series of appliances they thought would populate the home of tomorrow. Included was the Ultrasonic Bath or Human In Roll-lo Bathing (HIRB), a pod-like human washing machine that cleans, massages and dries the user in a fully automated 15-minute process.

Using a ladder, the bather climbs in through an opening on top of the machine, which stands about 2 meters (6 ft) tall. Once the desired water temperature is set and the main switch is activated, the pre-rinse cycle starts, spraying the user with jets of hot water for 5 minutes.

Next, the chamber fills up with hot water for a 3-minute massage bath. High-pressure jets create a powerful whirlpool, and scores of knobby, golf ball-sized "massage balls" suspended in the water pelt the body, delivering a vigorous massage intended to stimulate blood circulation. An ultrasonic wave generator creates a ticklish cloud of tiny air bubbles that lift dirt from the skin.

The bath is then followed by a 2-minute hot rinse cycle. Finally, a 5-minute dry cycle blasts the user with warm air, while a flood of infrared and ultraviolet light destroys any lingering germs.

  7. I seldom leave a response, but after browsing through a few of the responses on this
    page "Ultrasonic Bath - Automatic Washing Machine for Human, 1970".
    I do have a couple of questions for you if you do not mind.
    Is it simply me or does it give the impression like some of the responses look like they are coming from brain dead individuals?

    :-P And, if you are posting on other places,
    I'd like to follow you. Would you list of

  8. Games are not just for kids, and there are many that are not
    for kids at all. The ubiquity and efficacy of mobile advertising, including mobile gaming, are still at the immature stage;
    I believe that the real magnitude of mobile advertising in the near
    future could be massive, exceeding current estimates.
