Abstract: A fuel supply device includes an inlet pipe, a first end of the inlet pipe configured to be connected to an oil supply port and a second end of the inlet pipe configured to be connected to a fuel tank and an air flow path, an upstream side end of the air flow path configured to be open to the outside and a downstream side end of the air flow path configured to be connected to the fuel tank. The air flow path includes a negative pressure valve configured to move a valve body to open a valve port when the pressure in the fuel tank becomes a negative pressure and an air filter disposed upstream of the negative pressure valve.

Abstract: A fuel supply device includes a valve body and a filter unit accommodating an air filter and a valve cap are attached to a tubular portion provided on a side surface of an inlet pipe. When a fuel tank has a negative pressure, the valve body opens and the negative pressure is eliminated by clean atmospheric air introduction. A projection portion is provided on the filter unit side of the valve body. Accordingly, attachment of the valve body into the tubular portion and attachment of the tubular portion and the filter unit are reliably performed, the reliability of valve body opening and closing is improved, and attachment workability is improved.

Abstract: A rotary piston engine mounted on a vehicle is provided. The engine includes a rotary piston engine body mounted on the vehicle in an orientation where an output shaft of the rotary piston engine body extends substantially horizontally, an intake passage connected with an intake port formed in the rotary piston engine body, and an exhaust passage connected with an exhaust port formed in the rotary piston engine body. When the rotary piston engine is seen along the output shaft, the intake port is formed in a lower part of the rotary piston engine body and the exhaust port is formed in an upper part of the rotary piston engine body. The intake passage is disposed on one side of the rotary piston engine body and the exhaust passage is disposed above the rotary piston engine body.

Abstract: In an information processing system, a management apparatus reads all data from a storage device connected to an information processing apparatus, and stores the data as one image file in a backup storage device. A virus detection apparatus performs a virus detection process on the image file stored in the backup storage device in response to a request from the management apparatus, and if a computer virus is detected, performs a virus removal process on the image file. When the virus removal process is completed, the management apparatus reads and writes the image file from the backup storage device back to the storage device.

Abstract: A residual value of goods based on data is forecast based on a secondhand price database storing transaction data including the residual value of objects and age of the objects. A standardized forecast residual value is calculated for a prescribed future time based on the standardized residual value. The standardized residual value is calculated by modifying a residual value of the object included in the transaction data stored in the secondhand price database based on attribute values of a prescribed attribute of the object included in the transaction data. A non-standardized forecast residual value is determined by making adjustments corresponding to the attribute values of the object of which the residual value will be forecast.

Abstract: A portable power supply is foldable around a hinge. The portable power supply is provided at a side end surface of a solar cell module with a handle, and is provided at a side end surface of a solar cell module with a handle. The portable power supply is configured such that, when the portable power supply is in a folded position, an opening in the handle overlaps with an opening in the handle. According to this structure, the portable power supply can be easily carried, and can include the solar cell module having a light receiving surface, of which direction can be easily changed.

Abstract: Provided is technology for enabling an accurate forecasting of a residual value of goods based on data showing the similar trend, without making reduction of the number of data caused by ramification, when the subject goods have an attribute that may largely affect the residual value thereof. In order to achieve the above, the system according to the present invention comprises a secondhand price database storing transaction data including the residual value of the object and the elapsed year of the object etc.
