  • Publication number: 20220139587
    Abstract: To provide an iodine trapping apparatus capable of trapping organic iodine in a wide temperature range with high efficiency. The iodine trapping apparatus includes a first trapping agent 2 capable of trapping organic iodine in a gas in a nuclear power structure main body. The first trapping agent 2 contains a generating and trapping component which generates an iodide ion (I?) from organic iodine (RI) and traps the generated iodide ion, and a generating component which is different from the generating and trapping component, generates an iodide ion from the organic iodine at least at 100° C. to 130° C., and traps the generated iodide ion in the generating and trapping component.

  • Publication number: 20220139586
    Abstract: As an organic iodine remover that removes organic iodine in a containment vessel of a nuclear reactor, an organic agent (for example, an ionic liquid, an interfacial active agent, a quaternary salt, or a phase transfer catalyst) having a function of dissolving and decomposing the organic iodine and retaining iodine is used. The organic iodine remover is a substance composed of a cation and an anion. The organic iodine remover is, in particular, an organic iodine remover in which, in a structure of the cation of the organic agent, carbon or oxygen is bonded to, via a single bond, to a phosphorus element, a sulfur element or a nitrogen element, the number of carbon chains is 2 or more, and an anionic structure is configured with a substance with high nucleophilicity. By using such an organic agent, the organic iodine is removed with an efficiency of 99% or more.

  • Publication number: 20220051813
    Abstract: An organic iodine trapping apparatus and method efficiently traps organic iodine in a nuclear reactor container vessel. A liquid vessel contains a non-volatile liquid (e.g., ionic liquid or interfacial active agent solution) capable of decomposing organic iodine. An introduction pipe introduces a fluid containing organic iodine in the nuclear reactor container vessel to the non-volatile liquid. The non-volatile liquid is heated by heat in the nuclear reactor container vessel or reaction heat of the fluid in the nuclear reactor container vessel. Then, the trapping apparatus decomposes and traps the organic iodine. The organic iodine trapping method includes heating a non-volatile liquid capable of decomposing organic iodine by heat in the nuclear reactor container vessel or reaction heat of fluid in the nuclear reactor container vessel; making the fluid containing organic iodine pass through the heated non-volatile liquid; and decomposing and trapping the organic iodine in the non-volatile liquid.

  • Publication number: 20210260959
    Abstract: Coolant flowing from a compressor passes through a heat exchanger and opening-degree adjustable type of expansion valves for heating, and an external heat exchanger. The coolant passing through the external heat exchanger is capable of passing through an expansion valve and a heat exchanger for cooling, and an expansion valve and a heat exchanger for cooling a battery. A grille shutter to change an introduction state of traveling air is provided in front of the external heat exchanger. When pressure of the coolant (particularly, pressure of the coolant at a timing after the coolant passes through the external heat exchanger) is a specified pressure or lower, the grille shutter is closed, whereby the heat-exchange performance of the external heat exchanger is lowered.

  • Publication number: 20210261195
    Abstract: Provided is a suspension subframe structure that can activate a load path using an extension frame in an impact while avoiding increase in vehicle weight and also enables a suspension subframe to disengage from a vehicle body when an impact load is too large to be absorbed by the extension frame alone. The suspension subframe structure of the present invention includes a suspension subframe 110 that supports a suspension member 60 for a front wheel. The suspension subframe 110 includes: a body 111 that transmits an impact load input from a vehicle front side toward a vehicle rear side; a fixed portion 124 disposed near the body 111 and fixed to a vehicle body; and a connection portion 121 connecting the fixed portion 124 to the body 111. The connection portion 121 is provided with fragile portions 121f, 122g having a lower strength against a load in a vehicle front-rear direction than the body 111 and the fixed portion 124.

  • Publication number: 20210245649
    Abstract: A ramp system for a vehicle includes a control device. Using an obstacle detection device, the control device determines whether an obstacle exists within a ramp extension area. Upon determining that an obstacle exists within the ramp extension area, the control device causes a vehicle to move to a location in which no obstacle exists within the ramp extension area.

  • Patent number: 10790163
    Abstract: In a method for manufacturing a semiconductor sensor, an upper mold has a pair of projections on a wall surface opposing to side surfaces of a semiconductor chip in a first cavity and at positions closest to a second cavity. The projections project so as to reduce the space between the side surfaces of the semiconductor chip and the upper mold, so that a flow of a resin material from a first cavity to a second cavity is delayed. The resin material is filled in the first cavity prior to the second cavity. After a portion of a film corresponding to the first cavity is entirely brought into close contact with the upper mold, the resin material is filled in the second cavity.
