Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, a transmission mechanism, a movement regulating portion, a contact mechanism, and a first biasing portion. The movement regulating portion enables movement of a lever body to a second position when an end of the operation unit on a housing portion side is positioned at an initial position, and disables movement of the lever body to the second position when the end of the operation unit on the housing portion side is positioned closer to an operation surface than the initial position in a movable direction. The first biasing portion biases the plunger from an operating position toward a return position.

Abstract: A push button switch may include a housing, an operation unit, and, a lock lever unit. A lever body of the lock lever unit may have a locking portion capable of locking one end of a long jig in an extending direction. The housing may have a fulcrum projection that contacts an intermediate portion of the jig having the one end locked to a locking portion when the lever body is moved using the jig, and serves as a rotation fulcrum of the jig.

Abstract: A control device for controlling an engine provided with a fuel pump including a pressurizing chamber, a plunger inserted into the pressurizing chamber and which changes a volume of the pressurizing chamber, and an on-off valve configured to open and close a suction port, is provided. When a pressurizing cycle consists of a period of pressurizing stroke in which the volume of the pressurizing chamber is reduced to allow fuel to be pressurized and a period of suction stroke in which the volume of the pressurizing chamber is increased to allow fuel to be drawn into the pressurizing chamber, a closing cycle of the on-off valve is controlled so that a ratio of the closing cycle to the pressurizing cycle becomes smaller in a second combustion mode where a partial compression-ignition combustion is performed than in a first combustion mode where SI combustion is performed.

Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism integrates a deposition amount of deposits per unit time, and estimates a deposition amount of deposits on an injection hole of the fuel injection valve. The controller causes the fuel pressure adjustment mechanism to increase a fuel pressure, when the estimated deposition amount exceeds a predetermined value, and corrects the unit deposition amount acquired by the deposition amount estimation according to the set fuel injection timing of the fuel injection valve. The controller corrects such that as compared with the unit deposition amount when the fuel injection timing is set to a first timing away from a top dead center of the piston by a first period, the unit deposition amount decreases when the fuel injection timing is set to a second timing away by a second period longer than the first period.

Abstract: A push-button switch may include a housing, a plunger, an operation unit, a transmission mechanism, a contact mechanism, and a biasing portion. The plunger may have a first plunger that is disposed in series with the first plunger. The first plunger and the second plunger may be movable independently of each other. The contact mechanism may be configured to be opened/closed by movement of the second plunger.

Abstract: A terminal block includes a display-use moveable member which has a main body portion that can reciprocate in the direction intersecting a terminal connection surface and a contact moveable portion that extends along a guide surface, has a first end portion in an extension direction that is disposed so as to come into contact with a conductor portion in an electric wire passage portion and move in a first direction away from the terminal connection surface, and has a second end portion in the extension direction that is connected to the main body portion, and moves in an array direction in response to movement of the first end portion in the first direction to move the main body portion in a second direction toward the terminal connection surface.

Abstract: A push-button switch may include a housing, an operation unit, a lock lever unit, and a biasing portion. A lever support portion may be connected to the operation unit so as to be movable together with the operation unit when a lever body is positioned at a second position. The housing may have a deformation portion that, when the operation unit is pulled in an opening direction when the lever body is positioned at the second position, deforms the lever body so as to be capable of releasing the pressing to the lever body by a holding unit.

Abstract: A controller for controlling a fuel injection valve and a fuel pressure adjustment mechanism sets an air-fuel ratio of a fuel-air mixture to be generated within a combustion chamber to be equal to or leaner than a theoretical air-fuel ratio, based on an operating condition of an engine; drives the fuel injection valve, based on the set air-fuel ratio; estimates a deposition amount of deposits on an injection hole of the fuel injection valve, based on an operating condition of the engine; causes the fuel pressure adjustment mechanism to increase the fuel pressure, when the estimated deposition amount of deposits exceeds a predetermined value; and restricts the fuel pressure from increasing, even when the estimated deposition amount of deposits exceeds the predetermined value, as long as the fuel-air ratio is set to an air-fuel ratio leaner than the theoretical fuel-air ratio.
