Rotating cylinder type compressor

A rotating cylinder type compressor includes: a cylinder having a cylindrical shape and rotating about a central axis; a first rotor and a second rotor each having a cylindrical shape and rotating about an eccentric axis eccentric to the central axis of the cylinder; a shaft; a first vane; and a second vane. The first vane is slidably fitted to a first groove portion defined in the first rotor to define a first compression chamber. ... Nippon Soken Inc

Valve timing adjustment device

A planetary rotor includes: a planetary gear engaged with a driving rotor and a driven rotor on an eccentric side; and a single sequence type planetary bearing having an outer ring held by the planetary gear, an inner ring supported by a planetary carrier in the radial direction and receiving a restoring force from an elastic component, and a plurality of spherical rolling elements interposed between the outer ring and the inner ring. The outer ring is arranged to form a rolling contact part in contact with the spherical rolling element on the eccentric side, with a contact angle to a specific side in the axial direction. ... Nippon Soken Inc

Carrier apparatus

Driving wheels and non-driving wheels are installed to a lower portion of a case body. The driving wheels are driven by drive devices, respectively. ... Nippon Soken Inc

Flow rate measuring device

The present disclosure provides a flow rate measuring device for measuring a flow rate of a main flow flowing through a duct. The flow rate measuring device includes a bypass passage, a blow rate sensor, and a measurement body. ... Nippon Soken Inc

Lane keeping control system

A road-surface-condition estimation device is configured by a tire-side device and a vehicle-side device so as to grasp a road surface condition based on road surface condition data transmitted from a tire-side device. As a result, the road surface condition or a road surface μ of a traveling road surface of a vehicle can be accurately detected, and a more accurate lane keeping control can be performed according to the detection result. ... Nippon Soken Inc

Ultrasonic object detection apparatus

An obstacle detection apparatus includes: a transceiver transmitting a transmission wave and receiving an ultrasonic wave; a transmission controller; a receiver circuit detecting a signal level of a receiving wave; a distance calculator sequentially calculating a distance to an object reflecting the transmission wave; a memory storing the distance to the object; an obstacle determination device determining whether the object is an obstacle; and a reception level monitoring device monitoring the signal level of the receiving wave before the transmission wave being transmitted. When the signal level exceeds a predetermined threshold, the obstacle determination device sets a first number of determination data elements to an increased number of determinations for a predetermined period to be used for determining whether the object is the obstacle, as being larger than a second number of determination data elements used when the signal level does not exceed the predetermined threshold.. ... Nippon Soken Inc

Collective antenna device

A collective antenna device includes: a case having a gradually rising part in which spatial height increases continuously toward a rear part; a ground plate that is accommodated at a bottom part of the case; a first antenna element that is accommodated in the case and configured for a first frequency; and a second antenna element that is accommodated in the case and configured for a second frequency higher than the first frequency. The second element is accommodated in the case such that the second antenna element is located below or behind the gradually rising part and also located behind the first antenna element. ... Nippon Soken Inc

Relay device

A relay device includes a communication signal relay unit for relaying a communication signal and a wake-up signal relay unit for relaying, by bypassing the communication signal relay unit, a wake-up signal that is transmitted using a frequency band which is lower than a communication frequency band used in transmitting the communication signal. The communication signal relay unit includes a low frequency wave attenuation unit for attenuating a signal with a frequency band lower than the communication frequency band. ... Nippon Soken Inc

Diagnostic device

An ac component Δi addition unit of a diagnostic device superimposes an alternating current on an output current of a fuel cell. A zn calculation unit calculates a cell impedance with respect to the alternating current with regard to any of a plurality of cells. ... Nippon Soken Inc

Cylinder-rotation-type compressor

A cylinder-rotation-type compressor includes a discharge valve that is disposed in a cylinder and configured by a reed valve, a valve body portion that closes a discharge hole provided in the cylinder, and a support portion that couples the valve body portion with a fixing portion fixed to the cylinder. A shape of the valve body portion and a shape of the support portion are substantially symmetrical with respect to a line segment extending in a radial direction of a rotating axis. ... Nippon Soken Inc

Control system and mobile device

A control system includes: a transmission device that transmits a plurality of signals having different frequencies from one of a first communication unit mounted in a vehicle and a second communication unit mounted in a mobile device carried by a user in such a manner that the plurality of signals are combined to generate a predetermined composite signal in an area located at a distance from the first communication unit, the distance being not more than a predetermined distance; and a permission device that permits a predetermined action of the vehicle when the predetermined composite signal generated in the area from the plurality of signals transmitted by the transmission device is detected and an authentication signal transmitted by the second communication unit is authenticated as an authorized authentication signal for the vehicle.. . ...
