  • Patent number: 5813497
    Abstract: An apparatus (2) for serving and displaying food including a continuous watercourse (4) with food carriers (8) carrying various food trays. Patrons sit around a periphery of the watercourse. The food carriers are removably attached to an endless line (10) underneath the water by flexible wires (30) so that each food carrier is independently removable from the said watercourse. In addition, the flexible wires are positioned along the endless line so as to maintain a predetermined spacing between the food carriers in the watercourse. This predetermined spacing gives the patron adequate time to select sushi from adjacent food carriers and also gives the sushi chef adequate time to add sushi to adjacent food carriers.

  • Patent number: 5707164
    Abstract: An applicator or a tail clicking structure used in various modes of the applicators includes: a barrel cylinder storing a liquid in its inside; a clicking portion formed at the tail; a valve rod connected to the front end of a small-diameter pipe which is connected at its rear end to the clicking portion; a valve seat which is fixed at the front end opening of the barrel cylinder and slidably holds the valve rod at a position behind a large-diameter portion so that the large-diameter portion abuts or separates from the seat. The applicator further includes: a valve spring which is abutted at its rear end against the large-diameter portion so as to urge the valve rod backward; a spring receiver which is fitted into the front part of the valve seat so as to support the front end of the valve spring and has a guide hole for guiding the front end of the valve rod; and a pen tip to which the liquid inside the barrel cylinder is supplied during clicking operations.
