Patent number: 10597301Abstract: A high-concentration ammonia production method includes: synthesizing ammonia through electrolysis using water and nitrogen as raw materials; subjecting a resultant generation gas to treatment using an ammonia separation membrane or an ammonia PSA to separate the generation gas into high-concentration ammonia and a residual gas; recycling the residual gas as a nitrogen gas raw material of an ammonia synthesis reactor, and liquefying the high-concentration ammonia recovered through the ammonia separation membrane or the ammonia PSA; and subjecting an unliquefied gas separated from liquefied ammonia to the treatment using the ammonia separation membrane or the ammonia PSA again. According to the present disclosure, ammonia is synthesized by adopting an electrolysis method in which the synthesized ammonia substantially does not contain hydrogen, in combination with ammonia separation and recovery treatment using membrane separation or PSA.Type: GrantFiled: March 3, 2016Date of Patent: March 24, 2020Assignee: JGC CORPORATIONInventors: Tsutomu Kawasaki, Yoshiyuki Watanabe

Patent number: 10351011Abstract: An electric vehicle includes: a rotating electric machine; a photovoltaic cell; a first electricity storage device that is charged with electricity output from the photovoltaic cell; a second electricity storage device that is chargeable with electricity generated by the rotating electric machine, and serves as a power source for generating driving force of the vehicle; and a control device. The control device either prohibits charging the first electricity storage device or lowers an upper limit value of an SOC of the first electricity storage device while the control device is executing second charge control of charging the second electricity storage device with generated electricity generated by the rotating electric machine.Type: GrantFiled: January 3, 2018Date of Patent: July 16, 2019Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kazuki Kubo, Kiyohito Machida, Tsutomu Kawasaki

Patent number: 5360544Abstract: A deproteinization filler comprises an aggregate of hydroxyapatite fibers having a three dimensional network structure. The mean radius of pores defined by the aggregate is approximately 0.02 .mu.m to approximately 0.08 .mu.m, the specific surface of the aggregate is approximately 25 m.sup.2 /g to approximately 65 m.sup.2 /g and the mean diameter of particles defined by the aggregate is approximately 1 .mu.m to approximately 30 .mu.m. The filler is produced by a given method. The filler may be contained in a throwaway cartridge.Type: GrantFiled: November 13, 1992Date of Patent: November 1, 1994Assignees: Central Glass Company, Limited, Koken Co., Ltd., Moritex CorporationInventors: Yasuji Nakaso, Tsutomu Kawasaki, Wataru Kobayashi, Keiko Gondo, Hiroshi Iwase

Patent number: 4874511Abstract: In an adsorbent for use in chromatography comprised of secondary particles formed by aggregation of primary particles in the form of fine crystals of hydroxyapatite, the aggregated primary particles are sintered so as to be bonded together. The adsorbent is produced by heating the secondary particles at a temperature not lower than 300.degree. C. and not higher than the decomposition temperature thereof, and has significantly improved repetitive using properties. In a column system for use in chromatography, there are provided a main column packed with the above described adsorbent and a precolumn packed with a second adsorbent comprised of conventional hydroxyapatite particles. This column has also a significantly improved repetitive using properties.Type: GrantFiled: October 19, 1988Date of Patent: October 17, 1989Assignee: Koken Co., Ltd.Inventors: Tsutomu Kawasaki, Wataru Kobayashi

Patent number: 4709281Abstract: A flexible magnetic disk, rotatably housed in an apertured envelope to make up a disk cartridge, is loaded through an entrance slot in the housing of the apparatus to a preassigned position for data transfer with a pair of transducer heads on its opposite sides. Upon subsequent manipulation of a clamp know, one of the transducer heads is sprung into forced contact with the other transducer head via the magnetic disk therebetween. In order to avoid the direct contact of the two transducer heads as a result of the user's tampering with the clamp knob when the disk cartridge is not loaded in the apparatus, a head control mechanism is provided for holding the transducer heads away from each other when the disk cartridge is not loaded, even if the clamp assembly is then actuated inadvertently.Type: GrantFiled: June 19, 1985Date of Patent: November 24, 1987Assignee: Teac CorporationInventors: Kazuhiko Inoue, Tsutomu Kawasaki, Toshio Ihana

Patent number: 4694361Abstract: A clamp assembly is rotatably mounted to the dital end of a clamp arm proximally pivoted to the frame of the apparatus. The clamp arm is pivotable between an unclamping position, where the clamp assembly is away from a motor driven hub to allow the loading and unloading of a flexible magnetic disk in cartridge form, and a clamping position where the clamp assembly engages between itself and the drive hub the magnetic disk in a position for data transfer with a transducer head or a pair of such heads. The clamp arm is sprung from the clamping toward the unclamping position. Operatively engaged at a first end with the clamp arm is a clamp lever which is actuated as by a hand operated clamp knob for moving the clamp arm from the unclamping to the clamping position against the spring force. For simpler construction and easier assemblage, the clamp lever is made of sheet metal and formed to include a support portion bent right angularly from its second end.Type: GrantFiled: April 1, 1986Date of Patent: September 15, 1987Assignee: Teac CorporationInventors: Isamu Tsuchiya, Tsutomu Kawasaki, Yoshiaki Sakai
