Patent number: 7704380Abstract: In accordance with the present invention, a method of removing sulfide(s), which is safe, is effective over long periods at low cost, and exerts no adverse influences on the environment. The present invention relates to a method of removing sulfide(s), characterized in that a medium containing sulfide(s), including hydrogen sulfide and mercaptan(s), is allowed to come into contact with 2-bromo-2-nitropropane-1,3-diyl diacetate. Also, the present invention relates to the method, wherein the medium is a solid, liquid, or gas. In accordance with the present invention, sulfide(s), including hydrogen sulfide and mercaptan(s), can efficiently be treated so that they may be removed at low cost without the need for large-capacity equipment. In addition, the present invention can be safely practiced because there is no generation of byproducts that irritate the skin.Type: GrantFiled: April 5, 2005Date of Patent: April 27, 2010Assignee: K•I Chemical Industry Co., Ltd.Inventors: Toshihiko Shibata, Syoji Fukuyama

Patent number: 4939785Abstract: In a radio communication network system for use in carrying out communication with a plurality of radio telephone sets in a service zone by the use of a control channel and a plurality of speech channels, a connecting equipment unit (CE) is selectively operable in cooperation with a radio control unit (RCU) in a speech mode of forming a speech path through a selected one of the speech channels and an additional mode of selectively monitoring the control and the speech channels. The additional mode may be divided into first and second control modes for allowing and rejecting reception of a call with the control channel monitored, respectively. Alternatively, either a rest mode or a combination of rest and initial program loading modes may be added to the additional mode. A plurality of the connecting equipment units may be located in a single service zone and selectively put into the speech and the additional modes with only one of the connecting equipment units kept in the first control mode.Type: GrantFiled: May 31, 1988Date of Patent: July 3, 1990Assignees: Nippon Telegraph and Telephone Corp., Matsushita Communication Industrial Co., Ltd., NEC Corp.Inventors: Yoshitoshi Murata, Masahiko Hirono, Toshihiko Shibata, Fumio Suzuki, Mitsuo Sato, Tadao Hashimoto

Patent number: 4843622Abstract: For use in a mobile radio telephone network including radio telephone sets movable in an area divided into a predetermined number of zones, a communication control system includes a searching arrangement (25, 33) for searching one (15') of radio communication devices of the network as a searched communication device that is assigned to a present one of the zones into which a specific one (11') of the radio telephone sets has moved from a previous one of the zones. For operation of the searching arrangement, a communicating arrangement (22, 25, 32) of the system sends a call signal to a specific one of the radio communication devices that is assigned to the previous zone to transmit the call signal to the specific telephone set and receives a response signal transmitted from the specific telephone set if the specific telephone set were in the previous zone.Type: GrantFiled: April 4, 1988Date of Patent: June 27, 1989Assignees: NEC Corporation, Kabushiki Kaisha Toshiba, Matsushita Communication Industrial Co., Ltd., Nippon Telegraph and Telephone CorporationInventors: Akio Yotsutani, Yukihiro Sako, Toshihiko Shibata, Yoshitoshi Murata

Patent number: 4465382Abstract: When a steel sheet or the like is heated in a furnace to a temperature somewhat higher than the room temperature and is still or moved, its temperature can be measured by detecting the radiant energy therefrom. The measurement is normally difficult due to the influence of background noise of radiant energy from the surroundings, change of the transmittance factor of the environment or atmosphere for radiant energy, and change of the emissivity of the object to be measured.Type: GrantFiled: March 2, 1981Date of Patent: August 14, 1984Assignee: Nippon Steel CorporationInventors: Tohru Iuchi, Kunitoshi Watanabe, Toshihiko Shibata, Tetsuro Kawamura
