Abstract: An air conditioning control device includes: an operation pattern acquiring unit to acquire operation patterns indicating an operation target air conditioner in a room; a temperature data acquiring unit to acquire temperature data indicating a temperature measured by a temperature sensor when the air conditioner is in operation: a prediction model generating unit to generate, using a control amount of the air conditioner and temperature data acquired when the air conditioner is in operation as training data, a room-temperature prediction model for predicting the temperature measured by the temperature sensor when the air conditioner are in operation; and an operation pattern selecting unit to provide the control amount of the air conditioner to the room-temperature prediction model to acquire a prediction temperature from each of the room-temperature prediction models, and selects one operation pattern from the operation patterns on the basis of the prediction temperature.

Abstract: A string-attached cap is formed by connecting one end of a belt-shaped coupling member to a cap. In the string-attached cap, the coupling member is made of flexible resin, and has a ring as its part at one end, and the ring has an engaging part which is the inner periphery of the ring, the engaging part being slidably engaged with an annular groove formed in the outer periphery of the cap.

Abstract: Fuel reservoir apparatus can maintain and control pressure within a fuel tank at a low level during an operation of an engine, and also can prevent excessive refuelling. The fuel reservoir apparatus includes the fuel tank, a canister, a fuel vapor passage, a positive pressure valve, a solenoid valve, and a closure valve. The fuel tank stores liquid fuel to be supplied to the engine of an automobile. The canister can adsorb the fuel vapor. The fuel vapor passage connects the fuel tank to the canister. The positive pressure valve is provided in the fuel vapor passage for controlling pressure within the fuel tank, using a spring force. The solenoid valve is provided in the fuel vapor passage and adapted for opening during the operation of the engine to flow the fuel vapor towards the canister. The closure valve is provided in the fuel vapor passage for closing the fuel vapor passage when fuel is supplied to the fuel tank.

Abstract: A liquid fuel storage device is provided for use with an automobile system including an engine, a fuel tank, and a canister for absorbing fuel vapor during refueling. The device includes an air bag disposed in the fuel tank and constructed and arranged to inflate to occupy a space in the fuel tank in accordance with an amount fuel remaining in the fuel tank. Piping structure communicates the fuel tank with the engine for inflating the air bag by reducing pressure in the fuel tank when the engine is started. An air introduction pipe communicates with the atmosphere and includes a first valve mechanism for introducing air into the air bag and prevents air from escaping from the air bag after inflation thereof. An air emission pipe includes a second valve mechanism, which is opened only in refueling to emit air in the air bag during refueling. The air emission pipe is connected to the canister.

Abstract: A fuel tank comprising a filler tube, a communication passage, a charcoal canister, a cover member, a first magnetic member, and a second magnetic member along with the body of the tank. The filler tube is mounted at the top of the body of the tank. The canister is installed inside the communication passage connected with the filler tube. The cover member covers the top of the filler tube. The first magnetic member is disposed inside the filler tube and has a valve portion which opens and closes the communication passage. The second magnetic member is disposed outside the filler tube, and is moved when the cover member is opened or closed. The magnetic force produced by the second magnetic member can move the first magnetic member.

Abstract: A fuel tank system has a fuel tank, a fuel charging port extending from the fuel tank and disposed in the vicinity of an outer panel of a body and a fuel lid for covering the fuel charging port. The fuel lid is mounted such that it is movable substantially horizontally relative to a portion of the outer panel of the body corresponding to the fuel charging port and that a distal end of the fuel lid is capable of moving away from the fuel charging port and the outer panel. A fuel passage having an outlet disposed on a rear surface side of said fuel lid in such a manner as to be oriented downwardly is disposed in such a manner as to extend from said fuel tank. This fuel passage allows a liquid fuel overflowing during overfueling to flow.

Abstract: The fuel cutoff valve is provided which includes a case member having an outlet opening leading to a canister, and a float member disposed within the case member. The float member is provided including a valve which has a first annular seal member sealing the periphery of the outlet opening and a second annular seal member having a smaller diameter than that of the outlet opening, and a float body vertically below the values. A through hole in formed in each seal member of the valve. When the liquid fuel flows into the case and the floats member float the first seal member seals the periphery of the outlet opening. After the liquid fuel returns to the fuel tank, the valve is first opened between the second seal member having smaller diameter and the float body. Then since the valve also falls, even if the diameter of the outlet opening is large, the fuel cutoff valve will open.

Abstract: In the evaporated fuel control system according to this invention, a plurality of evaporator lines that connect the fuel tank and the engine are provided with two canisters, that is, a first canister installed in the first evaporator line used only during fuel filling and a second canister installed in the second evaporator line. These two canisters are controlled in such a way that the first canister is communicated with the fuel tank only during fuel filling and that only when the vapor fuel can be purged into the engine, the first canister is communicated with the engine. This construction prevents the vapor fuel in the tank from leaking out into the open air when the fuel is supplied into the fuel tank. It also allows the evaporated fuel to be recovered for reuse. This construction also assures safety in the event of an accident or system failure.
