Abstract: A product weight calculation system includes an accommodation section, a door portion that switches between a closed state and an open state, a weight detector that detects a weight of the products accommodated in the accommodation section and outputs an output value, a door detector that detects a state of the door portion, and a product weight calculation unit that calculates a weight value of a product taken out from the accommodation section based on a difference between a first output value and a second output value when an output value of the weight detector decreases from the first output value and becomes the second output value in a case where it is determined from a detection result of the door detector that the door portion is transitioned from the open state to the closed state, and sets an output value after the calculation as a new first output value.

Abstract: A label-affixing machine affixes a label, which is conveyed by a label conveying body, to the back surface of a product being conveyed. The label-affixing machine includes a label holding unit configured to hold a label so that an adhesive surface of the label faces outward, a pressing mechanism configured to press a label conveying body, which is disposed on a side facing the label holding unit, against the adhesive surface of the held label by moving the label conveying body toward the label holding unit, and a controller that controls the drive of the label conveying body and the pressing mechanism to affix the label to the back surface of the product.

Abstract: Provided is a stretch wrapping machine that can stably convey film even in a case where, for the purpose of wrapping, a holding component that holds the film is provided separately from belts for conveyance. The stretch wrapping machine is equipped with conveyance devices (22) having belt conveyance units and belt pressing mechanisms, a clamp device (23), a wrapping station, and a control device (9). At the wrapping station, product is pushed against film held by the clamp device (23), and the product is wrapped by the film. The belt conveyance units have upper belts and lower belts that sandwich end portions of the film. Pressing members (221e) of the belt pressing mechanisms apply force to the upper belts so that the force with which the upper belts and the lower belts sandwich the film increases.

Abstract: A power steering apparatus includes a worm gear that transmits a rotational force of an electric motor to a steering mechanism through engagement of a worm shaft and a worm wheel and a backlash adjustment mechanism that reduces backlash between the worm shaft and the worm wheel. The backlash adjustment mechanism has a ball bearing mounted to the worm shaft, a slider movable in a movement direction substantially perpendicular to a rotation axis of the worm shaft, a first sliding surface provided on an outer circumferential side of an outer race of the ball bearing, and a second sliding surface provided on the slider and brought in sliding contact with the first sliding surface such that forward movement of the slider in the movement direction causes relative sliding of the first and second sliding surfaces to bring the worm shaft closer to the worm wheel.

Abstract: In a power steering device employing both a worm speed reducer and a backlash adjuster for a worm gear of the speed reducer, the backlash adjuster has a slider configured to be movable in a longitudinal direction of a worm shaft, and a biasing member configured to bias the slider toward one side of the longitudinal direction of the worm shaft. Also provided is a guide member configured to bias the worm shaft in a direction for meshing with a worm wheel by a movement of the worm shaft in the meshing direction that the worm shaft approaches a rotation center of the worm wheel with a movement of the slider toward the one side of the longitudinal direction, and also configured to restrict a movement of the worm shaft in a direction opposite to the meshing direction of the worm shaft.

Abstract: An electric power steering device includes a rack bar; a pinion shaft meshing with the rack bar; a worm wheel provided on the pinion shaft; a worm shaft meshing with the worm wheel; an electric motor provided on the worm shaft; a first housing accommodating at least a part of the rack bar and the pinion shaft and includes a first bolt boss formed with a through-hole; a second housing; and a bolt. The second housing includes a worm-wheel accommodating portion accommodating the worm wheel, and a second bolt boss provided to have a shorter distance to the first housing than that of the worm-wheel accommodating portion, and formed with a female-threaded portion. The second bolt boss is opposed to the first bolt boss to cause the female-threaded portion to be continuous with the through-hole of the first bolt boss. The bolt fastens the first housing to the second housing.

Abstract: In a power steering system of this invention, a control valve is provided for supplying working fluid to a power cylinder by an amount proportional to a steering effort supplied to an input shaft and obstructing supply of working fluid to the power cylinder when a steering wheel is in a neutral position. A conversion mechanism which includes an operation rod (operating device) capable of operating the control valve is provided for converting the steering effort supplied to the input shaft to displacement of the operation rod. A directional control valve is provided which is disposed between the control valve and the power cylinder for switching supply of working fluid from one of cylinder chambers of the power cylinder to the other according to the direction of the steering effort on the input shaft while controlling discharge of working fluid from the cylinder chambers.
