Publication number: 20180164430Abstract: A sensor has an antenna. The antenna includes a radiation source and a wave guide. The radiation source is formed on a substrate. The wave guide internally propagates electromagnetic waves radiated from the radiation source and radiates the electromagnetic waves as a beam. The wave guide has a radiation-side opening in which a first direction and a second direction are orthogonal to each other, and the second direction is longer than the first direction. In a cross-sectional shape of the beam, perpendicular to a radiation direction of the beam radiated from the wave guide, a first direction and a second direction are orthogonal to each other, and the second direction is narrower than the first direction.Type: ApplicationFiled: May 13, 2016Publication date: June 14, 2018Applicant: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Akira KURIYAMA, Hideyuki NAGAISHI, Hiroshi KURODA

Publication number: 20160123261Abstract: A vehicle control apparatus that makes it possible to attempt fuel consumption improvement and exhaust gas reduction effectively without causing a sense of incompatibility in the driver is provided. When traveling following the preceding vehicle, kinetic energy required for an own vehicle in future is predicted on the basis of kinetic energy of the own vehicle, a velocity of a preceding vehicle, and a distance between the own vehicle and the preceding vehicle. It is determined whether there is kinetic energy enough for the own vehicle to be able to follow the preceding vehicle with inertial traveling, on the basis of the predicted kinetic energy and current kinetic energy. When it is determined that the kinetic energy is sufficient and the driving and traveling state of the own vehicle satisfies other traveling idling reduction conditions, control of stopping the engine is exercised.Type: ApplicationFiled: March 14, 2014Publication date: May 5, 2016Inventors: Takeo SHIBATA, Hiroshi KURODA

Patent number: 8558393Abstract: Miniaturization and acceleration of the operating speed of a System In Package (SIP) type semiconductor device in which a memory chip and a microcomputer chip are mounted over a wiring board are promoted. When mounting a microcomputer chip and a memory chip over an upper surface of a wiring board, the memory chip is disposed such that second conductive pads of the wiring board arranged along a first chip side (a side along which data system electrode pads are arranged) of the memory chip are positioned, in the plan view, in a region between an extended line of a third chip side of the microcomputer chip and an extended line of a fourth chip side of the microcomputer chip. Thus, a length of a data system wiring for coupling a data system electrode pad of the microcomputer chip with the data system electrode pad of the memory chip is minimized.Type: GrantFiled: April 9, 2012Date of Patent: October 15, 2013Assignee: Renesas Electronics CorporationInventor: Hiroshi Kuroda
