  • Publication number: 20240116046
    Abstract: A sensor package 10 includes a plurality of sensors 19 and a container 18. Each of the sensors 19 detects a detection target component in the fluid. The container 18 includes an inner channel 21 and a first surface os1. The plurality of sensors 19 are provided in the inner channel 21. The inner channel 21 enables the fluid to flow. An inflow opening 25 to the inner channel 21 and an outflow opening 25 from the inner channel 21 are formed on the first surface os1. An electrode group electrically connected to the plurality of sensors 19 is provided on a surface different from the first surface os1 of the container 18.

  • Patent number: 7644808
    Abstract: In an elevator door apparatus, an elevator door is capable of reciprocating between a door closure position for closing an elevator entrance and a door open position for opening the elevator entrance. The elevator door is driven by a door drive device. The door drive device is controlled by a door control device. The door control device adjusts the door open position based on control information for controlling an operation of an elevator, obtains a door opening/closing pattern for the elevator door to be opened and closed between the adjusted door open position and the door closure position, and controls the door drive device so that the elevator door is reciprocated in accordance with the obtained door opening/closing pattern.

  • Patent number: 5636715
    Abstract: The invention concerns a door structure for an elevator which allows a service engineer to easily adjust a gap between a vibration damping engaging mechanism on a cage sliding door, the width of which varies through the opening/closing operation of the cage sliding door, and each of vibration damping members spaced predetermined distances apart from both sides of the vibration damping engaging mechanism. In the door structure, the vibration damping engaging mechanism includes movable engaging vanes spaced predetermined distances apart from the vibration damping members. The movable engaging vanes are operated such that when the sliding door is present near to the full close and open positions, the spaces are larger than those when the sliding door is present in the middle of the opening/closing stroke of the sliding door.

  • Patent number: 5165505
    Abstract: The elevator landing door apparatus is provided with a door for opening and closing the doorway at an elevator landing zone, a rail for guiding the rollers of a hanger plate installed in an upright position in the upper part of the door just defined, and a sill for guiding a door shoe set in the lower part of the door laid out in the lower part of the doorway defined above. The elevator landing door apparatus is characterized in that a plate is set up in an upright position on the upper frame of three-side frames in the doorway defined above and a closure plate is set up in the upper part of the door defined above and forms an overlapping construction together with the plate when the door is shut. This closure plate is fitted out with an expansive material which expands by the effect of heat and thereby the clearance between the plate and the closure plate.

  • Patent number: 5156237
    Abstract: An apparatus operable on each elevator platform for opening or closing doors wherein the apparatus includes a pair of doors for opening or closing an inlet/outlet on the elevator platform, a rail for guiding the rolling movement of rollers carried by a hanger plate standing upright on the upper surface of each door and a door-sill arranged below said inlet/outlet for guiding the slidable movement of a door shoe at the lower end of each door. Each door is essentially composed of a door main body having a vertically extending reinforcement member for supporting the dead weight of each door and a thermal insulating panel fixedly secured to the door main body on the elevator platform side, the thermally insulating panel being filled with a thermal insulating material, and a decorative plate is adhesively secured to the front surface of the thermal insulating panel on the elevator platform side.
