Patent number: 9957170Abstract: A water treatment device generates a bubble in water to be treated inside a treatment tank, and treats the water to be treated through use of radicals that are generated by bubble electric discharge caused via the bubble. The water treatment device includes main electrodes for forming a main discharge area between a first main electrode and a second main electrode, auxiliary electrodes for forming a preliminary discharge area between a first auxiliary electrode and a second auxiliary electrode, and a bubble generator generating a bubble in water to be treated through use of an externally supplied gas.

Patent number: 7983075Abstract: Ferromagnetic layers have magnetizations oriented to such directions as to cancel each other, so that the net magnetization of the ferromagnetic layers is substantially zero. That is, the ferromagnetic layers are exchange-coupled with a nonmagnetic layer interposed therebetween, thereby forming an SAF structure. Since the net magnetization of the ferromagnetic layers forming the SAF structure is substantially zero, the magnetization of a recording layer is determined by the magnetization of a ferromagnetic layer. Therefore, the ferromagnetic layer is made of a CoFeB alloy having high uniaxial magnetic anisotropy, and the ferromagnetic layers are made of a CoFe alloy having a high exchange-coupling force.Type: GrantFiled: July 6, 2010Date of Patent: July 19, 2011Assignee: Renesas Electronics CorporationInventors: Takashi Takenaga, Takeharu Kuroiwa, Taisuke Furukawa, Masakazu Taki

Patent number: 7786725Abstract: A magnetic field detection apparatus capable of changing the detection range and detection sensitivity as desired for a specific application is disclosed. A magnetoresistance effect element is applied a bias magnetic field and an external magnetic field. The bias magnetic field and the external magnetic field are generated on the same straight line, and therefore the bias magnetic field functions to hamper the external magnetic field applied to the magnetoresistance effect element. Thus, the magnetization of the free layer of the magnetoresistance effect element is suppressed, and the rotational angle of the magnetized vector is reduced. As a result, the characteristic of the resistance value of the magnetoresistance effect element to the external magnetic field is shifted by an amount equivalent to the bias magnetic field.Type: GrantFiled: August 25, 2006Date of Patent: August 31, 2010Assignee: Mitsubishi Electric CorporationInventors: Taisuke Furukawa, Hiroshi Kobayashi, Takashi Takenaga, Takeharu Kuroiwa, Sadeh Beysen, Masakazu Taki
