Abstract: Provided is a fat and/or oil composition for heat cooking, comprising a fat and/or oil, and an alkali metal soap of a saturated fatty acid having from 4 to 16 carbon numbers, wherein an alkali metal content in the fat and/or oil composition for heat cooking is from 0.1 to 5.0 mass ppm, and a method of preparing the same. Also provided is a method of preventing deterioration of a fat and/or oil for heat cooking caused by heating, comprising the step of adding an alkali metal soap of a saturated fatty acid having from 4 to 16 carbon numbers to the fat and/or oil for heat cooking to produce an alkali metal content in the fat and/or oil composition for heat cooking of from 0.1 to 5.0 mass ppm.

Abstract: A texture automatic monitoring system for measuring surface texture of a road surface compacted by a road roller is measured by texture measurement equipment mounted on the road roller. The road surface texture measurement equipment comprises a height measurement instrument disposed on the compaction roller that measures height from the road surface, a moving distance detecting instrument that generates a signal corresponding to the moving distance of the road roller, a data processing unit that calculates the moving distance of the road roller based on the moving distance detecting signal, and calculates one or more road surface property values indicating the road surface texture by using the measured value of the height acquired from the height measurement instrument and the calculated moving distance, and a displaying unit which displays the calculated road surface property value.

Abstract: When gear ratio is abnormally increased due to failure of a secondary pulley rotation sensor or slip in a V belt, demand torque of an engine is rapidly reduced, and after upper limit regulation of a target secondary pulley pressure is performed for a second predetermined time, control of the target secondary pulley pressure according to an output torque of the engine is performed. Thereby, since an actual torque of the engine does not exceed a belt capacity capable of holding a belt by a secondary pulley pressure which is actually generated, when the secondary pulley rotation sensor fails, no slip occurs in the V belt.

Abstract: The shift control apparatus for a continuously-variable transmission includes a primary pulley; a secondary pulley connected with the primary pulley by a belt; a shift actuator that varies a speed ratio; a line pressure adjusting that adjusts a line pressure; a secondary-pressure adjusting section that adjusts a secondary pressure; and a control section that controls the shift actuator, the line pressure adjusting section, and the secondary-pressure adjusting section. Moreover, the control section includes a fail determining section that determines whether the shift actuator is under a failed condition.

Abstract: A hydraulic pressure control device is provide for a belt type continuously variable transmission that appropriately controls hydraulic pressure supplied to each pulley. The hydraulic pressure control device has a positive input torque calculation section that calculates a positive input torque that is inputted to a primary pulley from an engine; a negative input torque calculation section that calculates a negative input torque based on the calculated speed ratio and the positive input torque; and a hydraulic pressure regulation section that calculates a hydraulic pressure of hydraulic fluid supplied to each pulley depending on the sum of the positive input torque and the negative input torque and controls hydraulic pressure to each the pulley to the calculated hydraulic pressure.

Abstract: A transmission controller commands a demand torque of an engine to an engine controller according to an actual secondary pulley pressure that is detected by a secondary pulley pressure sensor when a vehicle speed is 0 km/h and a state wherein gear ratio is equal to or higher than a predetermined gear ratio is continued for a first predetermined time or more. Thereby, since an input torque corresponding to a secondary pulley pressure which is actually generated is inputted to a primary pulley even when a failure occurs in the secondary pulley rotation sensor, engine performance of a vehicle can be ensured.
