Abstract: A vehicle control device has a first calculating unit calculating a first arrival time until a vehicle reaches a lane change position where a first lane along which the vehicle is traveling and a second lane merge, or the first lane and the second lane separates, a second calculating unit calculating a second arrival time until another vehicle traveling along the second lane reaches the lane change position, and a speed control unit controlling the speed of the vehicle such that the vehicle enables to make a lane change to the second lane ahead of the other vehicle when the first arrival time is shorter than the second arrival time, and controlling the speed of the vehicle such that the vehicle enables to make a lane change to the second lane behind the other vehicle when the first arrival time is equal to or greater than the second arrival time.

Abstract: A vehicle speed control device 1 includes a lane detection unit 120 configured to detect a road outside line of a lane on which a host vehicle V is traveling, a target detection unit 121 configured to detect a target that is present outside the road outside line, and a speed control unit 123 configured to control a speed of the host vehicle V such that the host vehicle V passes a lateral side of the target at a speed lower than a speed of the host vehicle V when the target has been detected. After the host vehicle V has passed the lateral side of the target, the speed control unit 123 accelerates the host vehicle V up to the speed when the target has been detected.

Abstract: A hydraulic control apparatus is provided including: an electromagnetic valve that has an input port communicating with a supply destination unit of oil and a control port that is switched between communication and disconnection by resultant force of a hydraulic pressure of the supply destination unit and electromagnetic force; a variable displacement pump which has a suction port communicating with a supply source of the oil, an ejection port communicating with the supply destination unit, and a control chamber communicating with the control port and rotates in accordance with drive of the supply destination unit, in which an amount of the oil ejected to the supply destination unit through the ejection port changes in accordance with a pressure in the control chamber; and a control unit that controls a value of a necessary current that is caused to flow through the electromagnetic valve.

Abstract: A photosensitive polyimide resin composition has: a polyimide resin composition having a polyimide copolymer that is prepared by an imidation reaction of an acid dianhydride with a diamine; and a photosensitizer added to the polyimide resin composition. The polyimide copolymer has a polyimide constitutional unit-to-substituent ratio of 200 to 600, and the polyimide constitutional unit-to-substituent ratio is defined as C=A/B, where A represents a molecular weight of a repeating unit in a polyimide main chain constituting the polyimide copolymer, and B represents a total number of substituents in the repeating unit.
