  • Patent number: 9422760
    Abstract: A protector with a sensor is installed on a sliding door for detecting an alien substance by touch between two core wires in a hollow part. In a terminal part of the protector with the sensor, the core wires drawn out are connected with a resistor or leads joined with a control unit. A primary seal is formed by injection molding for coating wire connection parts and another end side of an insert and a secondary seal is formed by the injection molding for coating a part formed with the primary seal for forming an external shape of a product.

  • Patent number: 5952993
    Abstract: A virtual object display apparatus displays the action of an object at high speed. An environment information memory section stores environment information of a plurality of objects in a virtual space. A view information memory section stores view information of an extent of a view area of the virtual space. A visibility decision section determine whether each of the plurality of objects is visible in the view area in accordance with the environment information and the view information. An motion generation section generates motion for each of the objects in the virtual space in accordance with a decision result of the visibility decision section. A display section displays the motion of each of the objects generated by the action generation section.

  • Patent number: 5768565
    Abstract: An operation verification apparatus verifies the operation ability of an object for a user's operation. In the operation verification apparatus, an operation-imagination memory section stores operation-imagination information corresponding to a figure of each object in a three-dimensional virtual environment. The operation-imagination information is information relating to an operation method which a user imagines from the figure of a corresponding object. An environment information memory section stores environment information which includes position data and figure data of each object. An operation generation section generates operation method data for the object on which the user operates in accordance with the operation-imagination information and the environment information. A movable region memory section stores movable region data relating to a movable region within which each object can move in the virtual environment.
