Patent number: 10858328Abstract: According to the present invention, there is provided means for suppressing the occurrence of corrosion on the inner tube side in a heat exchanger and enabling continuous production for a long time period in a process for producing ethylene oxide. An embodiment of the present invention relates to a method for producing ethylene oxide, the method including: supplying a raw material gas including ethylene, molecular oxygen, and a chlorine compound to an ethylene oxidation reactor; subjecting ethylene and molecular oxygen in the raw material gas to catalytic vapor phase oxidation in the ethylene oxidation reactor in the presence of a silver catalyst, and thereby producing a gas including ethylene oxide, water, and a chlorine compound; and cooling a gas to be cooled including water and the chlorine compound using a heat exchanger.Type: GrantFiled: March 30, 2017Date of Patent: December 8, 2020Assignee: NIPPON SHOKUBAI CO., LTD.Inventors: Shingo Iguchi, Hideto Suzuki

Patent number: 10079087Abstract: In the dither current power supply control method, in order to prevent occurrence of a difference between the target average current and the detected average current, which is caused when a medium current (I0) between a dither large current (I2) and a dither small current (I1) and a waveform average (Ia) of the dither current are different from each other depending on a response time difference (a?b) between a rise time (b) and a fall time (a) of the dither current, negative feedback control is carried out by using a command medium current corresponding to the target average current corrected by a correction parameter based on experimentally measured data, thereby suppressing occurrence of a transient fluctuation error by the negative feedback control, so that a highly precise and stable load current is acquired.Type: GrantFiled: February 11, 2016Date of Patent: September 18, 2018Assignee: Mitsubishi Electric CorporationInventors: Shuichi Matsumoto, Masato Nakanishi, Shingo Iguchi, Hiroyuki Arita, Tomoaki Ogata

Patent number: 9972928Abstract: A plurality of pairs of contact terminals accommodated in a card edge connector include back surface members having one ends to which lead wires are connected and another ends being folded to form movable members. Until a circuit board of a control unit is inserted, end portions of the movable members are held in conductive contact with each other. When the circuit board is inserted, the movable members are separated and brought into contact with copper foil terminals. When the circuit board is removed, the movable members plastically deform and are opposed to each other with an initial gap smaller than a thickness dimension of the circuit board. With this arrangement, wiring inspection may be performed with opposed movable members shorted to one another, but for subsequent circuit board insertion at the second or subsequent insertion and removal of the circuit board, the movable members will be slightly separated by a gap to suppress slide abrasion during insertion.Type: GrantFiled: August 9, 2017Date of Patent: May 15, 2018Assignee: Mitsubishi Electric CorporationInventors: Shozo Kanzaki, Fumiaki Arimai, Hiroyoshi Nishizaki, Masato Nakanishi, Shingo Iguchi

Patent number: 8469336Abstract: A valve assembly in which, even if a housing corrodes, application of a radially inward compression force to a heat-resistant filter can be suppressed. The valve assembly includes the housing having a gas path and a valve shaft hole, a valve having a valve shaft movably inserted in the valve shaft hole and also having a valve element connected to the valve shaft, and tubular heat-resistant filters installed between the inner peripheral surface of the valve shaft hole and the outer peripheral surface of the valve shaft and capturing dust in exhaust gas. The housing is made of cast iron. The valve assembly further has reinforcement collars installed between the inner peripheral surface of the valve shaft hole and the outer peripheral surfaces of the heat-resistant filters. The reinforcement collars have higher rigidity than the heat-resistant filters. At least the surfaces of the reinforcement collars are made of a high corrosion resistant material having higher corrosion resistance than the cast iron.Type: GrantFiled: October 1, 2008Date of Patent: June 25, 2013Assignee: Taiho Kogyo Co., Ltd.Inventors: Katsumi Nakamura, Shingo Iguchi
