Abstract: When a vehicle starts, a surrounding state is securely provided to a driver. When a vehicle operation detector detects that there is a possibility that a parked vehicle starts, a vehicle surrounding state recognizer recognizes a state of surrounding of the vehicle based on images imaged by a plurality of cameras imaging a plurality of different areas of the surrounding of the vehicle. A parking style determiner determines a parking style executed in parking at a position where the vehicle now parks based on a recognition result of the vehicle surrounding state recognizer. A monitoring area setter sets a monitoring area where a driver is required to pay attention when the vehicle is started based on a determination result of the parking style determiner. A vehicle surrounding state provider provides a driver with information provision in the monitoring area.

Abstract: A geometric compression ratio in an engine main body 1 is set to 15 or less. Injection control means (ECU 40) performs a main injection of injecting fuel near a compression top dead center, and a preceding injection prior to the main injection at a specific region of predetermined load within an operating region on a relatively low-speed side. The injection control means performs, as the preceding injection, a pilot injection of performing injection at a timing such that at least part of a fuel spray reaches outside a cavity 31 on a top face of a piston, and a pre-injection of injecting fuel at a predetermined timing after the pilot injection, to suppress thereby ignition of the fuel injected by the pilot injection and shorten an ignition delay of the fuel injected by the main injection.

Abstract: A scale inhibition method for injecting an alkaline agent and a chelating agent into a fluid containing at least silica and calcium ions, and inhibiting generation of scale, includes feeding the chelating agent and the alkaline agent into piping channeling the fluid, mixing the fluid while causing the fluid to flow in a chemical-mixing part provided in the piping, and when either a pressure difference between the pressures or a flow rate difference between the rates of fluid flow at an inlet and an outlet of the chemical-mixing part exceeds a preset upper threshold, increasing the amount of the chelating agent fed, and feeding the chelating agent at an increased feed amount until the pressure difference or flow rate difference falls below a preset lower threshold.

Abstract: A polishing estimation/evaluation device includes a dividing unit, an overpolished area extracting unit, and a dummy modifying unit. The dividing unit divides a layout of an integrated circuit into a plurality of partial areas. The overpolished area extracting unit refers to an overpolishing condition indicating whether overpolishing occurs in a vicinity of a partial area based on a wiring density in the partial area and a wiring density in surrounding areas of the partial area, and extracts a partial area where the overpolishing occurs from the plurality of partial areas obtained by the division by the dividing unit. The dummy modifying unit modifies dummy wiring in the partial area where the overpolishing occurs extracted by the overpolished area extracting unit and/or dummy wiring in surrounding areas of the partial area to reduce the number of partial areas where the overpolishing occurs.
