Abstract: A connector assembly comprises a first connector and a second connector matable with the first connector in a mating direction. The first connector includes a housing and a slider held by the housing and slidable with respect to the housing in a direction intersecting the mating direction. The slider has a slider backlash restraining device disposed on an inner wall. The slider slides in a first direction to cause the second connector to move in the mating direction and slides in a second direction opposite to the first direction to cause the second connector to move in a direction opposite to the mating direction. The second connector has a connector backlash restraining device disposed on an outer wall of the second connector. The slider backlash restraining device abuts the connector backlash restraining device when the first connector is mated with the second connector.

Abstract: A crankshaft structure includes a crank pin section, a crank journal section, and a counter weight section arranged between the crank pin section and the crank journal section in a direction of a crankshaft. A crank arm section connecting the crank pin section and the crank journal section is formed with each of lateral edge portions extending substantially along a circumscribed tangential line connecting a base of the crank pin section and a base of the crank journal section when viewed in the direction of the crankshaft. Each of the lateral edge portions of the crank arm section includes an edge groove having a length extending between a central axis of the crank pin section and a central axis of the crank journal section when viewed in a direction to cross the crankshaft. The edge groove has a groove bottom portion formed between two reinforcing ribs.

Abstract: A therapy planning device includes: a condition acquiring unit configured to acquire therapy conditions including a position of an affected area, a necessary dose for the affected area, and a threshold dose for an area other than the affected area; a first planning unit configured to plan a first irradiation of irradiating a first irradiation field including the entire affected area to radiation; and a second planning unit configured to make a therapy plan satisfying the therapy conditions in combination of the first irradiation planned by the first planning unit and irradiation of an irradiation field including only part of the affected area.

Abstract: A valve train of an internal combustion engine having a swing of a link mechanism that is stabilized to stabilize the operating characteristics of an engine valve. A camshaft is provided together with a valve operating cam pivotally supported by the camshaft so as to operatively open and close an engine valve. A link mechanism allows a drive cam rotated integrally with the camshaft to swing the valve operating cam, and a drive mechanism swings the link mechanism, wherein opening and closing of the engine valve are started in a buffer section of the valve operating cam, and opening/closing timing of the engine valve is controlled by the drive mechanism swinging the valve operating cam via the link mechanism, without the provision of a buffer transition section and a buffer constant-speed section encountered at the time of transiting from a base circle to a cam lobe of the drive cam.

Abstract: A fatigue safety factor testing apparatus includes a FEM calculating section, a normalized stress calculating section and a fatigue safety factor calculating section. The FEM calculating section carries out a FEM calculation to meshes of a part to calculate a stress of each of the meshes of the part. The normalized stress calculating section calculates a normalized stress of a stress applied to each of the meshes with respect to a fatigue limit as a function of a temperature and material of each of the meshes. The fatigue safety factor calculating section calculates a fatigue safety factor of each of the meshes based on a normalized fatigue limit obtained by normalizing the fatigue limit and the normalized stress.
