  • Patent number: 11530758
    Abstract: In a vacuum ejector provided with a seal valve mechanism between a vacuum generation mechanism and a break flow path, the seal valve mechanism includes a valve plug that is biased toward a sealing opening from the break flow path side to block the seal opening, and is configured to open the seal opening by moving the valve plug away from the seal opening using a piston portion that operates according to supply air supplied from the vacuum generation mechanism.

  • Publication number: 20220355790
    Abstract: In a system, a parallel-parking number that is the number of the parking spaces aligned in the parallel-parking direction is acquired for each parking area. A vacancy number that is the number of vacant parking spaces is acquired for each parking area. Based on the parallel-parking number, a vacancy number threshold value is calculated that is a threshold value of the vacancy number for calculating a priority of each parking area, in one of which an automated-parking-target vehicle is to be parked. The priorities are calculated such that the priority of a parking area with the vacancy number equal to or larger than the vacancy number threshold value is higher than the priority of a parking area with the vacancy number smaller than the vacancy number threshold value. The automated-parking-target vehicle is caused to park preferentially in a parking space in the parking area with the higher priority.

  • Patent number: 11266280
    Abstract: A needle screw fitted to a compressed fluid supply part that is provided on a nozzle main body of a dust removing device adjusts the jet flow rate of a first compressed fluid from a jet nozzle by adjusting the flow path area of a first fluid supply path. Meanwhile, the suction flow rate of a second compressed fluid to be discharged into a discharge flow path is adjusted by adjusting the flow path area of a second fluid supply path by turning a nozzle main body-side adjustment screw that is provided on the nozzle main body and a suction nozzle-side adjustment screw that is provided on a suction nozzle.

  • Patent number: 10358750
    Abstract: A wear-resistant cloth has high wear resistance and is capable of exerting a long-term sliding property even under high-load environment as compared with conventional cloths. A wear-resistant multilayer fabric includes a sliding fabric and a base fabric. The sliding fabric includes polytetrafluoroethylene fibers A, the base fabric includes fibers B having creep ratio in a standard state and under 20% load of breaking strength, the creep ratio being lower than creep ratio of the polytetrafluoroethylene fibers, and the sliding fabric and the base fabric have mutual warps and/or wefts that are mutually entangled for bonding.

  • Patent number: 9657608
    Abstract: A valve timing varying device includes a housing rotor (20) composed of a front side housing member (22) and a rear side housing member (21), a vane rotor (30), and an urging spring (40) for rotationally urging the vane rotor in one direction with respect to the housing rotor. The urging spring has a coil part, a first end provided outside in a radial direction with respect to the coil part, and a second end provided inside in the radial direction with respect to the coil part. The front side housing member has a first latching concave part for latching the first end on an inside wall face. The vane rotor has an accommodation concave part for accommodating at least a part of the coil part at the front end side, and a second latching concave part for latching the second end in an area facing an opening.
