A vehicle seat, in which an occupant of a vehicle is to be seated, includes one or more vibration application units and a vibration application control processor. The one or more vibration application units are each configured to apply vibration to a portion of the vehicle seat. The portion is to be in contact with the occupant. The vibration application control processor is configured to cause each of the one or more vibration application units to vibrate with a vibration application waveform. The vibration application waveform includes a frequency component that is higher than or equal to 100 hertz and lower than or equal to 300 hertz and has an amplitude that varies in accordance with acceleration acting on the vehicle.

Vehicle seat

An electric power steering system includes an electric actuator, a current indication value generation unit, an actuator control unit, and a noise signal generation unit. The electric actuator is configured to apply assist force to a steering device. The steering device is configured to turn a steering wheel of a vehicle. The current indication value generation unit is configured to generate a current indication value in accordance with a target value of the assist force. The actuator control unit is configured to supply electric power to the electric actuator in accordance with the current indication value. The noise signal generation unit is configured to add a noise signal to the current indication value. The noise signal has a dominant frequency that is a frequency matching a control clock frequency of the vehicle or a harmonic component of the control clock frequency.

Electric power steering system

An accelerator pedal apparatus in which an acceleration operation for a vehicle is to be performed by a pedal configured to be operated by a foot includes a vibration application unit and a vibration application control processor. The vibration application unit is configured to apply vibration to the pedal. The vibration application control processor is configured to cause the vibration application unit to apply the vibration to the pedal with a vibration application waveform including one or both of a frequency component that is higher than or equal to 10 hertz and lower than or equal to 50 hertz and a frequency component that is higher than or equal to 100 hertz and lower than or equal to 300 hertz.

A fluid sterilization module includes an inner cylinder forming a processing flow path extending in a longitudinal direction, a first chamber communicating with the processing flow path via an opening on one end side of the inner cylinder, an inflow portion allowing an object to flow in the first chamber, an outflow portion allowing the object having passed through the processing flow path to flow out from an other end side of the inner cylinder, and a light emitting element facing an opening on the other end side of the processing flow path and irradiating the object passing through the processing flow path with ultraviolet light along the longitudinal direction. The first chamber has an inner volume equal to or more than &#x2154; of the cube of an equivalent inner diameter of the processing flow path and equal to or less than 3 times of inner volume of the processing flow path.

Ultraviolet light irradiation device

An ultraviolet irradiation device having higher processability and interfacial adhesiveness, and allowing downsizing is provided. The ultraviolet irradiation device includes an enclosure configured to include a hollow portion being formed inside and being capable of introducing an irradiation object, an outer periphery of the enclosure being covered by a covering portion, and a light source configured to be arranged in an area not covered by the covering portion of the enclosure and project light toward the hollow portion. The covering portion is formed of thermoplastic resin fiber. Processability and interfacial adhesiveness can be improved by forming the covering portion with thermoplastic resin fiber. Consequently, a structure advantageous for downsizing of the ultraviolet irradiation device is provided.

Ultraviolet irradiation device

A fluid sterilization module includes an inner cylinder forming a processing flow path, a case portion in which the inner cylinder is accommodated, a member provided between an outer circumferential surface of the inner cylinder and an inner circumferential surface the case portion, a first chamber located in a region on a side of one end portion of the inner cylinder with respect to the member, in a gap between the inner cylinder and the case portion, a second chamber located in a region on a side of the other end portion of the inner cylinder with respect to the member, and a light emitting element provided in at least one of the one end portion and the other end portion of the inner cylinder, and configured to emit ultraviolet light to the object passing through the processing flow path.

In a sub-frame module that is used to attach a set of left and right wheels in pair to a vehicle body, a sub-frame attached to the vehicle body and left and right hub carriers, to which the left and right wheels in pair are attached, are connected by left and right link arms to be capable of swinging. A stabilizer is laid across the left and right rear link arms, and a holder that holds the stabilizer is supported by an vehicle body side member that is provided in a bush attached to the vehicle body. The holder is fixed to the vehicle body by attaching the vehicle body side member to the vehicle body.
