Abstract: A method to control valves in a cylinder operating in a multi-stroke cylinder mode. Valves are controlled to improve engine emissions as operating conditions vary.
Abstract: A plurality of coils wound around a stator magnetic-pole core are connected together and connected to output wires by use of a bus bar. The bus bar having a generally cylindrical body portion is disposed at one axial end of the stator magnetic-pole core, around which the coils are wound such that clearances are formed within magnetic-pole core slots, with an axial clearance formed between the bus bar and the coils. The body portion has such a radial dimension that at least a portion of the clearances within the magnetic-pole core slots is left uncovered. Air holes are formed in the motor housing on opposite sides of the stator magnetic-pole core to thereby form cooling air passages extending through the magnetic-pole core slots.
Abstract: A pressure-resistant tank for liquids includes a plurality of differently shaped diecast parts (1, 2) made of a first aluminum alloy (cast alloy). The diecast parts (1, 2) are connected by means of a closed weld seam welded with an electron beam with the use of a second aluminum alloy (wrought alloy). The second aluminum alloy has especially a hydrogen content of less than 0.2 mL per 100 g of wrought alloy. The tank for liquids is especially an anesthetic tank and the anesthetic is desflurane.

Abstract: A base side connecting mechanism (30) comprises a holder (40), a plug metal (50) and a sleeve (70). The plug metal (50) has a shaft (51) and a lock pin (52) projecting from the shaft (51) in a radial direction. The sleeve (70) is disposed to move slidingly along an axial direction of the shaft (51), is supported by the plug metal (50) through a wave washer (60), and receives biasing power toward an antenna mast (100) side. A mast side connecting mechanism (120) comprises a circular cylinder portion (121). The circular cylinder portion (121) is formed to press the sleeve (70) along the axial direction and has loosely penetrated portions (124, 125) in which the lock pin (52) can move along a circumferential direction and in which other end portions are large-diameter.
