Abstract: A compound of the formula (I): wherein Ring A is substituted or unsubstituted pyridine ring, Y is substituted or unsubstituted alkyl, etc., R1 is hydrogen, or substituted or unsubstituted alkyl, etc., R2 is hydrogen or lower alkyl, R3 is lower alkyl, Z is 1) —D1—Q [D1 is direct bond or divalent C1-8 hydrocarbon, etc., Q is hydroxy, carboxyl, etc.], or 2) —D2M—E—W [D2 is direct bond or divalent C1-8 hydrocarbon, etc., M is oxygen, sulfur, etc., E is direct bond or divalent C1-8 hydrocarbon, etc., W is hydroxyl, carboxyl, etc.], or a prodrug thereof, or a pharmaceutically acceptable salt of the same, which exhibits acyl-CoA: cholesterol acyl transferase (ACAT) inhibitory activity, and is useful as an agent for treatment of hyperlipidemia and atherosclerosis.

Abstract: A controller in which a starting state is detected for the controller to control a displacement varying mechanism of the pump by the detected result of the starting state to minimize the discharge capacity of the pump, thereby minimizing the driving load of the pump. In this manner, the starting properties of the engine are improved to reduce consumption of energy at the starting time.

Abstract: A controller for a hydraulic fluid flow control apparatus determines a quantity necessary for loading/unloading operations according to a signal from a lever operating degree detector, and controls a variable displacement type hydraulic pump to obtain the quantity. Accordingly, unnecessary hydraulic fluid flow in the hydraulic apparatus is reduced. The controller determines when a vehicle is stopped according to a signal from a clutch ON-OFF detector or a neutral sensor, and can raise the rpm of an engine. Therefore, when the loading/unloading operations are being executed while the vehicle is stopped, there is no need to operate the accelerator pedal.
