  • Publication number: 20150168269
    Abstract: An event is classified as a fault of hardware or a fault of a system or a control system. When the event is classified as the fault of the hardware, the event is expanded into lower events, physical quantities of the event and the lower events are acquired, and it is examined whether the event is expanded properly or not based on relationship between the physical quantity of the event and the physical quantities of the lower events. When the event is classified as the fault of the system or the control system, a block diagram of the system or the control system is created, and the event is expanded into the lower events based on input/output relationship in the block diagram of the system or the control system.

  • Patent number: 8157105
    Abstract: An oil strainer includes a body which has lower and upper walls and an inside space between the lower and upper walls, a filter substantially horizontally disposed within the body so as to divide the inside space into lower and upper space sections, an outlet port provided on the upper wall of the body and communicated with the upper space section, and an inlet port provided on the lower wall of the body and communicated with the lower space section. The lower wall includes a first area in which an inlet port periphery of the inlet port is disposed, and a second area separate from the first area. A vertical distance between the filter and the lower wall in the first area is smaller than a vertical distance between the filter and the lower wall in the second area.
