Patent number: 11941985Abstract: Disclosed is a vehicular environment estimation device capable of accurately estimating a travel environment around own vehicle on the basis of a predicted route of a mobile object or the like, which is moving in a blind area. A vehicular environment estimation device that is mounted in the own vehicle detects a behavior of another vehicle in the vicinity of the own vehicle, and estimates a travel environment, which affects the traveling of another vehicle, on the basis of the behavior of another vehicle. For example, the presence of another vehicle, which is traveling in a blind area, is estimated on the basis of the behavior of another vehicle. Therefore, it is possible to estimate a vehicle travel environment that cannot be recognized by the own vehicle but can be recognized by another vehicle in the vicinity of the own vehicle.Type: GrantFiled: November 5, 2021Date of Patent: March 26, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Katsuhiro Sakai, Hiromitsu Urano, Toshiki Kindo

Publication number: 20200103868Abstract: A machining assist system includes a knowledge database, a receiver, a control unit, and a display. The knowledge database stores various pieces of information indicative of know-how concerning a machining method and a machining facility. The receiver receives a question. The control unit executes a driving solver and a solution-providing solver so as to search the knowledge database using a search condition based on the question and derive a response. The display presents the response. The response includes a plurality of measures, priorities assigned to the measures, and progress information indicative of a search process and a search route. The search process includes a plurality of factors to be used to derive the measures. The search route is a link between the factors. The search process and the search route are visually presented on the display.Type: ApplicationFiled: September 24, 2019Publication date: April 2, 2020Applicant: JTEKT CorporationInventors: Hiroshi Kojima, Yoshihiko Yamada, Takayuki Azuma, Toshiki Sakai, Shigetoshi Noritake, Kazunari Teramoto

Publication number: 20170257797Abstract: The exemplary embodiments enables flexible audio services to be provided in a radio communication system in which a base station is shared by a plurality of communication providers. A radio communication system includes: a first user equipment configured to store information for identifying a first communication operator for a first communication; a second user equipment configured to store information for identifying a second communication operator for a second communication; and a base station. The base station is configured to execute the first communication and the second communication, measure a radio resource used in the base station, compare, when the radio resource exceeds a predetermined threshold value, a control level of the base station with at least one of a control level of the first communication or a control level of the second communication.Type: ApplicationFiled: September 1, 2015Publication date: September 7, 2017Applicant: NEC CorporationInventor: Toshiki SAKAI

Patent number: 9446499Abstract: A truing device is supported so as to be elastically movable in the Z-axis direction, which is parallel to a grinding wheel rotational axis, and elastically movable in the X-axis direction in which a grinding wheel cuts into the truing device, and includes a movement restriction device that controls prohibition and permission of elastic movement. The method includes: causing a surface of the grinding wheel to contact the truing device in the X-axis direction; and correcting a shape of the grinding wheel when the grinding wheel cuts into the truing device until the amount of elastic movement of the truing device in the X-axis direction reaches a first predetermined amount, by controlling the movement restriction device to prohibit elastic movement of the truing device, and thereafter causing the grinding wheel to further cut into the truing device in the X-axis direction by a second predetermined amount.Type: GrantFiled: March 13, 2015Date of Patent: September 20, 2016Assignee: JTEKT CORPORATIONInventors: Naoto Ono, Satoshi Okubo, Toshiki Sakai

Patent number: 9254549Abstract: A grinding machine includes: a grinding wheel of which movement in an X direction and a Z direction is controlled and that grinds a workpiece; and a truing unit that is installed at a predetermined position and that trues a machining surface of the grinding wheel. The truing unit includes: a movable table that is installed to be movable in the X direction relative to a support member; a truer that is rotatably installed in the movable table and that trues the machining surface of the grinding wheel; and an X-direction pressing mechanism that presses the truer in the X direction along with the movable table.Type: GrantFiled: April 28, 2014Date of Patent: February 9, 2016Assignee: JTEKT CorporationInventors: Toshiki Sakai, Satoshi Okubo, Shinji Soma, Naoto Ono

Patent number: 9238297Abstract: In a machining method of supporting a workpiece having a cylindrical machined portion such that the workpiece is rotatable and feeding a grinding wheel in a radial direction, a start diameter that is a diameter including a measurement start point on a surface of the machined portion is measured, and, after the measurement start point passes through a machining application portion, an end diameter that is a diameter including a measurement end point is measured. An actual grinding depth at the time when the measurement start point is machined is computed by the equation, U=|D0?D1|, a runout of the machined portion is computed from a relative difference in the actual grinding depth (U) between positions of the machined portion in a rotational direction, and infeed control of the grinding wheel is executed such that the runout is removed.Type: GrantFiled: November 20, 2012Date of Patent: January 19, 2016Assignee: JTEKT CORPORATIONInventors: Toshiki Sakai, Masashi Yoritsune, Yasuo Niino

Publication number: 20100220649Abstract: If a packet received from a communication terminal is larger in size than a maximum transmission unit used between a wireless base station and a gateway apparatus and also if it cannot be fragmented, an echo request packet of a size not larger than the maximum transmission unit is generated and transmitted to the gateway apparatus. Thereafter, if an echo reply packet corresponding to the echo request packet is received from the gateway apparatus, an ICMP data packet including the value of the maximum transmission unit is generated and transmitted to the communication terminal.Type: ApplicationFiled: August 20, 2009Publication date: September 2, 2010Inventor: TOSHIKI SAKAI
