Patent number: 9297991Abstract: Standing wave-generating planar wave illumination units generate two light-wave planar waves using light from a light source assembly and irradiate a sample surface with a standing wave produced by interference of the planar waves on the sample surface. A bias planar wave illumination unit generates a bias planar wave using light from the light source assembly and irradiates the sample surface with the wave. The bias planar wave is synchronized with the standing wave to alternately oscillate to positive and negative with an equal electric field displacement irrespective of the position on the sample surface across a reference time specified in advance when the displacement of the standing wave has a value “0” at the respective positions on the sample surface, and oscillates at a bias amplitude specified in advance to raise the displacement of the standing wave on the sample surface to only a positive or negative displacement.Type: GrantFiled: February 25, 2013Date of Patent: March 29, 2016Assignees: THE UNIVERSITY OF TOKYO, NATIONAL UNIVERSITY CORPORATION SHIZUOKA UNIVERSITYInventors: Satoru Takahashi, Kiyoshi Takamasu, Ryota Kudo, Shin Usuki

Patent number: 9275497Abstract: Surface form data as an object to which a grain is applied is inputted to a data input part. A plane polygon forming part projects a borderline of the surface form data on an x-y plane and changes the borderline to poly-lines to form a two-dimensional polygon mesh having the borderline as an outer edge. A three-dimensional polygon forming part connects together intersections of straight lines extending to a z-axis direction from apexes of the polygon mesh and the original surface form data to obtain a three-dimensional polygon mesh and further make the mesh uniform. A grain forming part obtains an amount of displacement from texture data corresponding to the apex of the three-dimensional polygon mesh through a texture model formed and deformed in a texture model deforming part to set polygon data obtained by connecting together the apexes respectively displaced in normal directions as the surface processed data.Type: GrantFiled: February 26, 2010Date of Patent: March 1, 2016Assignees: CALSONIC KANSEI CORPORATION, National University Corporation Shizuoka UniversityInventors: Mamoru Kikuta, Kenjiro Miura, Daijiro Uzuyama, Kenji Takahashi

Patent number: 9236879Abstract: According to this A/D converter, a first A/D conversion operation for performing integral A/D conversion and a second A/D conversion operation for performing cyclic A/D conversion are realized based on control of operational procedures in a same circuit configuration. Moreover, in the first A/D conversion operation, since a capacity of a capacitor used in the integration of an output signal is greater than a capacity of a capacitor used for storing an input analog signal and a standard reference voltage, the analog signal that is input in the integral A/D conversion is attenuated according to the capacity ratio and subject to sampling and integration. Consequently, the voltage range of the analog signal that is output in the integral A/D conversion also decreases according to the capacity ratio of the capacitors, and the A/D converter can be therefore constructed with a single-ended configuration.Type: GrantFiled: February 17, 2012Date of Patent: January 12, 2016Assignee: NATIONAL UNIVERSITY CORPORATION SHIZUOKA UNIVERSITYInventor: Shoji Kawahito

Patent number: 9202902Abstract: A semiconductor element encompasses a charge-transfer path defined in a semiconductor region (34.35), configured to transfer signal charges, (b) a pair of first field-control electrodes (42a, 42b) laminated via an insulating film on the semiconductor region so as to sandwich the charge-transfer path in between, and a pair of second field-control electrodes (43a, 43b) arranged separately from and adjacently to the first field-control electrodes (42a, 42b). By applying field-control voltages differing from each other, to the first and second field-control electrodes (43a, 43b), a depleted potential in the charge-transfer path is changed, and a movement of the signal charges transferring in the semiconductor region is controlled. Because electric field can be made constant over a long distance along the charge-transfer direction, a semiconductor element and a solid-state imaging device, in which problems caused by interface defects and the like are avoided, can be provided.Type: GrantFiled: August 1, 2013Date of Patent: December 1, 2015Assignee: National University Corporation Shizuoka UniversityInventor: Shoji Kawahito
