Publication number: 20220051813Abstract: 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.Type: ApplicationFiled: November 12, 2019Publication date: February 17, 2022Inventors: Sohei FUKUI, Motoi TANAKA, Masaaki TANAKA, Fumio TOTSUKA, Tomoharu HASHIMOTO, Kazuo TOMINAGA

Publication number: 20210260959Abstract: 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.Type: ApplicationFiled: December 30, 2020Publication date: August 26, 2021Applicant: MAZDA MOTOR CORPORATIONInventors: Yasuhiko NAKAHARA, Masaaki TANAKA, Taiki SHIGEMORI, Masaki NISHINO

Patent number: 10790163Abstract: 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.Type: GrantFiled: January 17, 2019Date of Patent: September 29, 2020Assignee: DENSO CORPORATIONInventor: Masaaki Tanaka
