A hydraulic circuit includes a first oil path, a second oil path, a hydraulic control circuit, a third oil path, a check valve, and a relief valve. The first oil path links to a discharge port of a first oil pump. The second oil path links to a discharge port of a second oil pump. In the hydraulic control circuit, a first regulator valve is disposed downstream of a confluence point of the first oil path and the second oil path. The third oil path connects a suction port of the first oil pump and a strainer. The check valve is provided in the third oil path and restricts a movement of oil toward the strainer side. The relief valve is provided in the third oil path and discharges oil in the third oil path to an outside when a pressure in the third oil path exceeds a reference pressure.

Hydraulic circuit

A hydraulic control device for a hydraulic actuation machine including a main oil pump configured to supply oil to the hydraulic actuation machine, a sub oil pump configured to temporarily supply oil to the hydraulic actuation machine based on a drive request so as to compensate for an oil shortfall when supply of oil from the main oil pump to the hydraulic actuation machine is stopped or insufficient, and a drive unit configured to drive the sub oil pump, wherein when an elapsed time elapsed from a time point when the sub oil pump is driven reaches a predetermined time, the hydraulic control device generates an air discharge command for discharging air accumulated in the sub oil pump and outputs the air discharge command to the drive unit, and the drive unit drives the sub oil pump to discharge the air accumulated in the sub oil pump based on the output air discharge command.

Hydraulic control device for hydraulic actuation machine, hydraulic control method for hydraulic actuation machine, and non-transitory computer-readable medium

An infrared projector including: a light source which radiates an infrared ray; and an emitter which emits visible light when exposed to infrared light, wherein the emitter is provided on a position where the infrared ray radiated from the light source reaches.

Infrared projector

A display system for a vehicle is provided with a sensor sensing a traveling condition of a vehicle, an image pick-up device executing an image pick-up to take an image of an outside of the vehicle, a display displaying the image taken by the image pick-up device, an image irregularity determination section determining whether there is an image irregularity or not in the image taken by the image pick-up device based on the traveling condition of the vehicle sensed by the sensor, and a display control section executing a display control processing with respect to one of the image still containing the image irregularity and the image previously picked up and not containing the image irregularity when the image irregularity determination section determines that there is the image irregularity in the image.

Display system for vehicle and method of controlling the same

An object detection apparatus has a laser radar and near infrared ray projector. The projector has a near infrared ray projecting lens, a laser oscillator, a laser receiver and a swivel actuator. The laser oscillator emits a laser beam, while the swivel actuator scans the laser beam in a laser scanning range. A laser receiver receives the laser beam reflected on an object. The near infrared ray projecting lens diverges the laser beam and projects a near infrared ray into a range including the laser scanning range and a near infrared ray projecting range. The near infrared camera obtains an infrared image by receiving a near infrared ray reflected on the object. An electronic control unit calculates object information based on the received laser beam when detecting an object and causes the near infrared ray to be projected to obtain the infrared image when acquiring the infrared image.

Object detection apparatus, especially for vehicles

In an system in which a night vision image photographed with an infrared camera installed at a vehicle is displayed at a head-up display, the display state of the night vision image displayed at the head-up display is changed as a high beam switch enters an ON state to allow the driver to check the image of the field far ahead on the head-up display.

On-vehicle night vision camera system, display device and display method

This communication game system comprises a client systemand a game server systemfor communicating with the client system. The game server systemcomprises a databasefor storing group information which relates a plurality of client systems to each other as a battle group. The game server systemis structured to decide a battle combination among the client systemsbelonging to the same battle group, to perform a battle by managing the sending and receiving of data between the client systems determined by the above-mentioned combination, and to decide the next combination in accordance with the results of the battle. Each client systemhas its own character select function and chat function when watching games.
