Patent number: 8357272Abstract: A quantum dot manipulating method and a generation/manipulation apparatus are provided which can control the size of a large number of generated quantum dots on or below the order of percent which is required for optical applications of the dots. Quantum dots are generated by shining a dot production laser (4a) onto a solid object (3) in a quantum dot production/manipulation apparatus (1) containing superfluid helium (7) therein. A dot manipulation laser (5a) is shone onto the generated quantum dots to manipulate the quantum dots.Type: GrantFiled: February 25, 2009Date of Patent: January 22, 2013Assignee: Japan Science and Technology AgencyInventors: Tadashi Itoh, Masaaki Ashida, Hajime Ishihara, Takuya Iida

Patent number: 7683457Abstract: A CaF2 buffer layer (3) is formed on a CaF2 (111) substrate (2) by an MBE method. Furthermore, a CuCl thin film is grown on the CaF2 buffer layer (3) by the MBE method while irradiating it with an electron beam to form an electro beam irradiation film (1a). Subsequently, a CuCl thin film is grown by the MBE method without the irradiation of electron beam to form an electron beam non-irradiation film (1b), thereby thus forming a CuCl thin film (a) including the electron beam irradiation film (1a) and the electron beam non-irradiation film (1b). Consequently, a CuCl thin film (1) exhibiting high planarity and crystallinity can be formed.Type: GrantFiled: November 30, 2004Date of Patent: March 23, 2010Assignee: Japan Science & Technology AgencyInventors: Tadashi Itoh, Masaaki Ashida

Patent number: 7683361Abstract: A method for generating a quantum-entangled photon pair is such that a biexciton in such a state that the angular momentum is 0 is generated through two-photon resonance induced by irradiating a semiconductor substance, e.g., CuCl, with two parent photons (angular frequency ?i). A photon pair is then generated by splitting the biexciton thus generated simultaneously into two photons (angular frequencies ?s and ?s?). Since the photon pair is generated by splitting such biexciton having an angular momentum of 0, it has a quantum entanglement with regard to polarization. Since the photon thus generated has a wavelength substantially equal to that of the parent photons, photons of shorter wavelength in a quantum entangled state can be generated.Type: GrantFiled: November 2, 2004Date of Patent: March 23, 2010Assignee: Japan Science & Technology AgencyInventors: Keiichi Edamatsu, Tadashi Itoh

Patent number: 5596747Abstract: A database operation control system includes a database checker, a database saver, a database diagnoser, a logical image creator, a database creator, and a database restorer. The database checker checks an access time taken for retrieval processing, and records an access time increase in an access time record file. The database saver saves data from the database to a save file. The database diagnoser compares the access time increase with a reorganization start increase as a reference value obtained from the access time record file to diagnose whether recognition is necessary, and informs the database saver of the necessity of the execution of reorganization processing of the database, if it is determined that reorganization is required. The logical image creator decomposes data of the save file into logical units to create logical images, and stores them in a logical image file. The database creator creates a restoration file. The database restorer restores data from the restoration file to the database.Type: GrantFiled: June 1, 1995Date of Patent: January 21, 1997Assignee: NEC CorporationInventors: Nobue Katabami, Tadashi Itoh, Yasutomo Takahashi

Patent number: 4598299Abstract: A deflection control ink jet recording apparatus is capable of compensating for dislocation of dots at all the deflection steps. A deflection amount is adjusted with respect to two points to determine a correlationship between the amplification gain, charge code and deflection amount, so that an amplification gain and a charge code free from dislocation is set for each deflection step. A charge code compensation value is detected to add it to or subtract it from a predetermined charge code assigned to each deflection step, thereby setting a charge voltage code to be assigned to each deflection step in a printout operation.Type: GrantFiled: November 9, 1983Date of Patent: July 1, 1986Assignee: Ricoh Company, Ltd.Inventors: Takahisa Koike, Takao Fukazawa, Kazumi Ishima, Toshiharu Murai, Tadashi Itoh, Toshifumi Kato, Koichiro Jinnai

Patent number: 4595948Abstract: An ink jet head prints an image by superposing individual dot matrices of at least two colors. A computing unit receives electrical input signals representing the image and generates and feeds corresponding electrical signals representing the individual matrices of the at least two colors to the head means for printing. The computing means includes matrix generator means for generating the matrices in such a manner that the total number of dots to be printed in all of the matrices is limited to a first predetermined value which is less than the maximum possible total number of dots which can be printed in all of said individual dot matrices, and the total number of dots to be printed in the matrices which are formed by superposed dots of different colors is limited to a second predetermined value which is less than said first predetermined value.Type: GrantFiled: October 12, 1983Date of Patent: June 17, 1986Assignee: Ricoh Company, Ltd.Inventors: Tadashi Itoh, Toshiharu Murai, Koichiro Jinnai, Kazumi Ishima, Takahisa Koike, Toshifumi Kato, Takao Fukazawa
