  • Publication number: 20010044894
    Abstract: A plurality of application servers, a client, an integrated authentication server and a security information management server are connected to a network. A user having different combinations of user ID's and passwords or certificates for a plurality of kinds of services processed by the plurality of application servers makes requests for services to the individual application servers through the client by using a common integrated certificate. An application server receiving the integrated certificate from the client transfers it to the integrated authentication server. The integrated authentication server checks information of the security information management server to decide whether the right of the user to access the service is valid and when valid, transmits to the application server a combination of a user ID of the user and a password or a certificate concerning the service.

  • Patent number: 5943710
    Abstract: The invention provides a water jet generating a system capable of applying water jet massage while a bather takes a bath by generating water jet at an appropriate pressure. More specifically, water is sucked in from a water source or a bathtub by a pump, and water jet is spouted out at an appropriate pressure through water jet spouting means or a nozzle so as to generate water jet in the bathtub. The water jet can beat at the surface of the body of the bather, and a complex stimuli caused by thermal effect of water or hot water and pressure of water jet and friction occurring between the water jet and the skin of the bather can be applied to the skin of the bather, attaining massaging effects of the water jet with ease.

  • Patent number: 5918326
    Abstract: A water jet massaging system is capable of applying water jet massage while a bather is taking a bath by producing a water jet at an appropriate pressure, and having enhanced operability by preventing sticking of a water intake and a nozzle to the body of the bather. More specifically, water is sucked in from a water source by a pump, and water jet at an appropriate pressure is injected through a nozzle so as to beat at the surface of the body of the bather, attaining massaging effects of water jet with ease. Further, the water intake is provided with passages for water flow to prevent blockage of water flow, and the nozzle is provided with an inclined surface on the side opposite the body to slow down velocity of water flow, preventing a sticking phenomenon.

  • Patent number: 4139803
    Abstract: In conjunction with an AC plasma display panel a light detecting pen is employed to designate coordinate points on the panel. Circuitry is employed to scan the electrodes of the panel with sustain voltage pulses at predetermined intervals and determine the coincidence of a selectively applied sustain voltage pulse with light detected by the light pen to indicate the location of the light pen with respect to the panel. A negative scanning method is also disclosed wherein coincidence between a sustain voltage pulse which is selectively not applied and the non-detection of light indicates the location.
