摘要： Provided is a method for removing noise of a positron emission tomography (PET) signal in a PET-magnetic resonance imaging (MRI) fusion device without using an MRI radio frequency (RF) shield that degrades image quality. The method includes: receiving a PET output signal from a PET-MRI fusion device and performing analog filtering by removing noise components due to an RF pulse frequency based on the relationship between the frequency of the PET output signal and a magnetic resonance (MR) RF frequency (Larmor frequency); and converting the filtered signal into a digital signal through sampling. The method allows acquisition of molecular-level images without declined performance of a PET detector in MRI environment.

摘要： A vehicle engine (70) is connected with a belt-type continuously variable transmission (1) via a clutch (32). The transmission (1) transmits torque via a belt (43) between a pair of pulleys (41, 42), and varies the transmission torque according to a supply of oil pressure. The clutch (32) engages by means of oil pressure supplied as a shift lever is changed over from a neutral range to a drive range. An oil pressure supplying device (10, 44, 45, 46) supplies the oil pressure required to transmit torque between the belt (43) and the pulleys (41, 42), and the oil pressure for engaging the clutch (32). Slippage between the belt (43) and the pulleys (41, 42) is prevented during engagement of the clutch (32) by restricting the output torque of the engine (70) over a predetermined period of time.

摘要： An abnormal oil pressure reduction determining device has an oil pressure sensor which detects a real oil pressure, a sensor which detects a vehicle running state, and a controller which sets an oil pressure command value for an oil pressure control mechanism. The controller computes the lower limiting oil pressure which is possible in the present vehicle running state, and when the real oil pressure is less than this lower limiting oil pressure and the pressure difference between the real oil pressure and oil pressure command value exceeds a reference value, determines that there is an abnormal pressure reduction due to a fault in the oil pressure control mechanism. Even if the oil pressure of the transmission has dropped abnormally due to some reason, the abnormal oil pressure reduction determining device determines the situation without fail.

摘要： A vehicle is provided with an engine (1), an automatic transmission (2) connected to the engine (1), a detection device (21–24, 31) which detects an operating state of the transmission (2), and a torque regulating mechanism (1a, 1b, 1c) which regulates a torque of the engine. When the operating state of the transmission (2) is in a predetermined drive state and the torque of the engine (1) is to be reduced, a selection is made, based on the operating state of the transmission (2), between a first torque reduction control whereby the torque of the engine (1) is reduced rapidly and temporarily, and a second torque reduction control whereby the torque of the engine (1) is reduced continuously, and more smoothly than in the first torque reduction control. The torque of the engine (1) is then reduced by the selected one of the first torque reduction control and the second torque reduction control.
