  • Patent number: 11617233
    Abstract: A thermal insulation structure for a vehicle window device is provided with a heater is disposed on a vehicle interior side, a heat-receiving component that is provided between the window and the heater, and that, by receiving heat from the heater, imparts radiant heat to the window, and a thermal insulation layer that is provided at a surface of the heater on an opposite side from the heat-receiving component, wherein the thermal insulation layer is formed by mutually superimposing a plurality of thermal insulation materials, and of the plurality of thermal insulation materials, a thermal insulation material on a closest side to the heater has greater heat resistance than a thermal insulation material on a furthest side from the heater, and the thermal insulation material on the furthest side from the heater has a lower thermal conductivity than the thermal insulation material on the closest side to the heater.

  • Publication number: 20210092803
    Abstract: A sheet heater comprises a sheet form heating unit configured from a wire heater. The heating unit comprises a first heating unit positioned along a peripheral edge of the area subject to heating, and a second heating unit positioned at an area surrounded by the first heating unit. The second heating unit comprises a plurality of meandering parts, with mutually adjacent meandering parts overlapping each other in the meandering direction. In the heating unit, the width (WL) of the wire heater is greater than the width (WP) between mutually adjacent wire heaters.

  • Patent number: 5278643
    Abstract: A monitoring apparatus in a game hall where a large number of game machines are disposed in lines includes a monitoring video camera, preset monitoring condition memories, drivers, abnormality sensors, a judgement processor and a monitor. The monitoring video camera includes a zoom lens, and is installed at a position for monitoring at least two of the game machines simultaneously. The preset monitoring condition memories store preset monitoring conditions of the monitoring video camera for taking a close-up of each of the game machines through the zoom lens. The drivers set the monitoring video camera according to the preset monitoring conditions and the abnormality sensors monitor a game situation. The judgment processor analyzes information based on the abnormality sensors and upon deciding that an abnormal state exists, controls the driver so as to set the monitoring video camera according to the preset monitoring conditions for the game machine corresponding to the abnormal state.
