When the control device determines that the level Ge of the slapping sound is a determination value Gc or more, it discontinues the warm-up promotion processing and starts to operate the pump 30.

摘要： PROBLEM TO BE SOLVED: To surely deliver a rod-shaped work one by one in a correct posture. SOLUTION: A work carrying pair 6 is formed by a fixed wall 3 which is faced to a work waiting part 1 and supports a work W from the side, and a movable rod 4 which slides in the vertical direction on the side of the fixed wall 3 and supports the work W from the lower side. The work carrying pair 6 is tilted toward the work waiting part 1. A plurality of work carrying pairs are arranged in a hierarchy so that the movable rod 4 on the upper layer is slidable on the fixed wall 3 on the lower layer. The fixed wall 3 is covered over an upper end face 4a of the movable rod 4. Similarly, the movable rod 4 is covered over an upper end face 3a of the fixed wall 3. When the work is lifted by the movable rod 4, the center of gravity of unnecessary works and works of defective posture is shifted from the upper end face, and dropped downward. The center of gravity of only the works loaded on the upper end face 4a in the desired posture is kept and the work is prevented from being dropped. Thus, the work can be delivered successively one by one in a correct posture.

摘要： PROBLEM TO BE SOLVED: To improve productivity. SOLUTION: A torsion bar 10 is inserted in a conductor 12. At that time, a clearance between an outer diameter of an end portion 10A of the torsion bar 10 and an end portion 12A of the conductor 12 takes the minimum value that is easy to be practically inserted. Next, an end portion 14A of an output shaft 14 is fitted with the end portion 12A of the conductor 12. At that time, a press-in tightening margin of the outer diameter of the end portion 12A of the conductor 12 and the end portion 14A of the output shaft 14 is made to be 3% to 15% of the outer diameter in the end portion 12A of the conductor 12. Consequently, the end portion 14A of the output shaft 14 is pressed in and fitted with the end portion 12A of the conductor 12, and simultaneously the end portion 12A of the conductor 12 is decreased in diameter and fitted with the end portion 10A of the torsion bar 10. Therefore, the torsion bar 10, the conductor 12, and the output shaft 14 can be fitted with each other at a time. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To prevent generation of excessive piston slap due to local thermal deformation of a cylinder when cooling capability is temporarily reduced by stopping circulation of a cooling water during engine warming-up in a cooling device of an internal combustion engine.SOLUTION: A pump control unit 410 of a control device 40 stops the driving of a pump 30 by releasing a clutch 31 when a cooling water temperature detected by a water temperature sensor 51 is equal to or less than a determination water temperature to stop circulation of the cooling water in a cooling water path 20. A signal processing unit 420 of the control device 40 extracts a signal component of a frequency band of piston slap from a detection signal of a knocking sensor 52 through a variable band filter 421. When the pump control unit 410 determines that the signal component is equal to or more than the determination level, the pump control unit causes the cooling water to circulate in the cooling water path 20 so that a cylinder 12 is cooled by bringing the clutch 31 into an engagement state to bring the pump 30 into a driving state.
