A pad clip for a disc brake apparatus is provided with a sandwiching portion for sandwiching a projecting portion formed in a support member of the disc brake apparatus. The sandwiching portion includes an upper hold piece, a lower hold piece, and a connecting piece for connecting the upper hold piece and lower hold piece to each other. The upper hold piece includes a hold claw having a leading end urged toward an upper surface of the projecting portion and in contact with a vertically extending wall surface of a recessed groove formed in the projecting portion, and a spring piece for urging the hold claw. When the sandwiching portion sandwiches the projecting portion, the spring piece is not in contact with the upper surface of the projecting portion.

The invention discloses an optical deorbit method for tethered towing of space debris and belongs to the field of spacecraft attitude and orbit dynamics and control. The implementation method includes: establishing a coupling dynamics model of the in-plane orbit of a tethered towing system through a Lagrange method; solving the optimal fuel problem of transfer orbit by adopting an optimization method for orbit transfer and ensuring a wide range of optimal orbit transfer of the tethered towing while system stabilizing the altitude of tethered towing system; at the end of towing, controlling thedebris by swinging and releasing to enable the debris to gain the maximum initial velocity and fly to the farther orbit, and completing the debris removal task while reducing fuel consumption duringthe debris removal process. With the method, wide range optimal orbit transfer of the tethered towing system can be guaranteed, and meanwhile, the attitude of the tethered towing system can be kept stable to remove the space debris stably; besides, the final swing control makes the debris fly further into the orbit, and fuel consumption during the debris removal process is reduced.

A seatbelt mechanism (S) comprises a chip anchor (12) disposed to one of right and left sides of a seat bottom (3) of the vehicle seat (1) and coupled to a tip end of the seatbelt (10), and a tongue anchor (14) disposed to the other of the right and left sides of the seat bottom (3) and engaged with a tongue plate (13) disposed to an intermediate portion of the seatbelt (10). A pretensioner mechanism (21) moves both the chip anchor (12) and the tongue anchor (14) substantially at the same time to actively tenses the seatbelt (10) when the vehicle collision occurs. A moving distance of the chip anchor (12) is substantially equal to a moving distance of the tongue anchor (14).

An inkjet printer includes: an inkjet head including nozzles and a nozzle surface tilted in a tilt direction with respect to a horizontal plane; a purging unit configured to discharge ink from the nozzles and attach the discharged ink to the nozzle surface; and a wiper configured to wipe the nozzle surface in a wiping direction orthogonal to the tilt direction. At least a portion of the wiper including an end of the wiper on a lower side in the tilt direction is tilted or curved toward a downstream side in the wiping direction toward the lower side in the tilt direction. The portion of the wiper is configured to wipe the nozzle surface while pushing the ink attached to the nozzle surface from the lower side to an upper side in the tilt direction.

A fuel tank opening and closing device is equipped with a flap valve mechanism arranged inside the tank opening forming member, having an opening and closing member for which the inlet is opened and closed by being pressed by the tip of the fueling nozzle, a shaft provided at the tip of the opening and closing member, and a bearing mechanism provided on the tank opening forming member for supporting the shaft so as to be rotatable. The bearing mechanism has a shaft support recess in which the shaft is inserted and a plurality of shaft restriction projections provided projecting from the wall surface of the shaft support recess, and the shaft restricting projections have a cross section arc shaped shaft support surface such that there is contact with a portion of the outer periphery of the shaft.

A flying head slider includes a slider body. The upstream or leading end of a bottom surface on the slider body is defined along a first datum line extending in the lateral direction of the slider body. The first datum line may be set perpendicular to the longitudinal centerline of the slider body. The upstream or leading end of the front air bearing surface is defined along a second datum line intersecting the first datum line at a predetermined inclined angle. As the incidence angle of an airflow colliding against a step defined at the leading end of the front air bearing surface gets decreased, the pitch angle of the slider body also gets decreased in the flying head slider during flight.
