Patent number: 9234970Abstract: A microcontroller unit (3) measures and records a radiation exposure dose obtained from a detection output of a radiation detection unit (2), and when the radiation exposure dose or dose rate exceeds a predetermined threshold, issues a warning to the user by lighting or blinking a LED (4). The LED (4) is placed opposite a light-emitting/receiving element (62) of an electrical non-contact input device (6) provided on a display device (5), and is also used to transmit and receive recorded radiation dose data and a command or data transmitted from the non-contact input device (6). According to such a configuration, a portable radiation dosimeter that is compact and can manage the radiation exposure dose for a long term without placing a burden on the wearer can be realized.Type: GrantFiled: February 8, 2013Date of Patent: January 12, 2016Assignee: National Institute of Advanced Industrial Science and TechnologyInventor: Ryouichi Suzuki

Patent number: 8905184Abstract: An electric power steering apparatus includes a steering column that is swung around a tilting spindle during tilt adjustment, a fixing bracket that supports the steering column through the tilting spindle, and an electric motor that is supported by the steering column and used as a steering auxiliary. The fixing bracket includes a pair of side plates facing each other with the steering shaft therebetween in a vehicle width direction and a connection member through which the pair of side plates are connected together. Either one of the pair of side plates is provided with a first restraining portion that restrains the steering column from rotating in a first rotation direction around the tilting spindle. The remaining one of the pair of side plates is provided with a second restraining portion that restrains the steering column from rotating in a second rotation direction opposite to the first rotation direction.Type: GrantFiled: February 22, 2011Date of Patent: December 9, 2014Assignee: JTEKT CorporationInventors: Norio Hosomi, Tadakatsu Take, Junya Takekawa, Ryouichi Suzuki, Shuta Togashi

Patent number: 8538632Abstract: An electric power steering apparatus is provided that has a controller by which no current flows in one phase among current paths of three phases for supplying electric power from a motor driving circuit to a three-phase brushless motor and currents that have an identical absolute value and that have different signs flow in the other two phases. Thus, the status at one energization angle on the driving current waveform of the three-phase brushless motor can be given continuously and relatively-high currents can simultaneously flow in opposite directions in the contacts inserted to the two phases. By flowing of such high current in the contacts, a secure conduction check can be performed and foreign matters on the surface of the contact can be fused or thermally destroyed.Type: GrantFiled: October 21, 2008Date of Patent: September 17, 2013Assignees: JTEKT Corporation, Mitsubishi Electric CorporationInventors: Takanobu Takamatsu, Ryouichi Suzuki, Yuuichi Fukuyama, Yuji Takatsuka

Patent number: 8378561Abstract: An electron emitter includes a guard electrode 13 on the outer circumferential side of a carbon film structure 10 which is formed on a substrate 7 by plasma CVD method. This guard electrode 13 includes a curved surface portion (a curved surface portion that curves from top toward a side opposite to the film-forming direction) 13a convex in a film-forming direction of the carbon film structure 10. A curvature radius R1 of an outer-circumferential-side portion of the curved surface portion 13a is larger than or equal to a curvature radius R2 of a carbon-film-structure-side portion of the curved surface portion 13a.Type: GrantFiled: July 30, 2009Date of Patent: February 19, 2013Assignee: Life Technology Research Institute, Inc.Inventors: Yoshihisa Ishiguro, Masanori Haba, Ryouichi Suzuki

Publication number: 20120194057Abstract: Provided are an electron emitting body having a high electron beam density and an X-ray emitting device embedding the electron emitting body. The electron emitting body has a substrate, the surface of which forms a concave surface, and a carbon film comprising a large number of projections made of carbon and expanded two-dimensionally. The carbon crystal grows such that first a swell portion (22) gradually becomes larger and then a needle-like portion (23) grows from the head of the swell portion (22). The needle-like portion (23) has a graphene sheet obliquely wound therearound in a multi-layer fashion and has a hollow inside. The axis of a carbon projection (21) thus formed is substantially orthogonal to a line tangent to the concave surface (11), so that the axes of a plurality of the carbon projections (21) intersect with each other at the focal point (F) of the concave surface (11).Type: ApplicationFiled: February 23, 2010Publication date: August 2, 2012Applicant: LIFE TECHNOLOGY RESEARCH INSTITUTEInventors: Ryouichi Suzuki, Yoshihisa Ishiguro, Masanori Haba

Patent number: 6094078Abstract: A PLL circuit taking a shorter time to accomplish phase locking with reduced jitter is provided. A phase/frequency detector circuit section includes: a first phase/frequency detector having phase/frequency difference detection characteristic substantially free from a dead zone; and a second phase/frequency detector having phase/frequency difference detection characteristic with a dead zone of a predetermined width. If the phase/frequency difference between a reference signal and a signal to be compared is too small to be detected by the second phase/frequency detector, only the first phase/frequency detector detects the phase/frequency difference. On the other hand, if the phase/frequency difference between the reference signal and the signal to be compared is sufficiently large, then both the first and second phase/frequency detectors detect phase/frequency difference.Type: GrantFiled: October 19, 1998Date of Patent: July 25, 2000Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Ryouichi Suzuki
