Abstract: A screw compressor for compressing a working medium sucked through a suction opening and discharging the compressed working medium through a delivery opening, wherein the screw compressor includes: a male rotor and a female rotor that rotate while meshing with each other; a casing that houses the male rotor and the female rotor and is provided with a bore which forms a working chamber designed, together with the male rotor and the female rotor, to compress the working medium; a drive unit that rotationally drives at least one of the male rotor and the female rotor; a working chamber closing unit that forms a suction port for sucking the working medium into the working chamber and closes the working chamber when the working chamber reaches a specified capacity; and a suction space that connects the suction opening and the suction port to allow communication therebetween, wherein an open space that connects the suction opening and the suction port to allow communication therebetween is provided between a shaft

Abstract: An electric power steering apparatus arranged in the vicinity of a heat source mounted on a vehicle includes: a rack shaft that turns a road wheel; an output shaft provided with a pinion gear engaged with a rack gear of the rack shaft; a worm wheel provided on the output shaft; a worm shaft engaged with the worm wheel; an electric motor that drives the worm shaft; and a controller that controls driving of the electric motor, and wherein at least a part of the controller is arranged on the opposite side of the heat source such that a rack housing is sandwiched between at least a part of the controller and the heat source, the rack housing accommodating the rack shaft.

Abstract: An electronic display device includes a plurality of displays, a sub-memory, and a control circuit. The displays display content. The sub-memory temporarily stores image information of images to be displayed on the displays. The control circuit controls presentation on the displays. Further, upon updating images displayed on the displays, the control circuit rewrites the image information stored in the sub-memory in advance into the image information of the image currently displayed on the display to be updated.

Abstract: A steering device with an impact absorbing mechanism includes an upper column tube configured to support a steering shaft, a lower column tube configured to be movable relative to the upper column tube and an upper fixing bracket to be coupled to the upper column tube and including a cut on the side of a steering wheel. The impact absorbing mechanism includes a bracket fixing portion fixed to the upper fixing bracket, a capsule portion fixed to a vehicle body and engaged with the cut, and a breaking portion connecting the bracket fixing portion and the capsule portion and configured to be broken by relative movements of the upper fixing bracket and the capsule portion. A connected position of the breaking portion to the capsule portion is near a front side of the vehicle body.

Abstract: An impact absorbing device includes an impact absorbing plate provided integrally with the second column tube, the impact absorbing plate being configured to absorb the impact energy, and a pressing member provided integrally with the first column tube, the pressing member being configured to generate deformation resistance by pressing and deforming the impact absorbing plate. A guide hole extending in the axial direction of the steering shaft is formed on the impact absorbing plate, and a guide that relatively moves along the guide hole upon relative movement in the axial direction of the first column tube and the second column tube is provided integrally with the first column tube.
