An asphalt emulsion comprising water, asphalt, (A) an emulsifier selected from the group consisting of specific aliphatic amines, aminated lignins, imidazolines having a hydrocarbon group having 7 or more carbon atoms, and amidobetaines having a hydrocarbon group having 7 or more carbon atoms, (B) a polyphenolic compound, and (C) at least one member selected from the group consisting of anionic polumeric dispersants, hydroxycarboxylic acids and/or (D) at least one member selected from the group consisting of saccharides, sugar alcohols and polyhydric alcohols, which is excellent in storage stanility, mixability with aggregate and low foaming properties of the emulsion itself, in adherence of the products of breaking thereof to aggregate, and in stripping resistance of the construction executed by the use of the emulsion.

An automatic transmission includes a casing housing a transmission mechanism and having a wall with a through-hole. A first plurality of electronic components is mounted exterior to the casing and a second plurality of electronic components is mounted on the interior of the casing. A sealed wire terminal is mounted in and closes the through-hole 21. An electronic control unit is mounted in the sealed wire terminal 22 and cables electrically connect the electronic control unit to the first and second pluralities of electronic components. The sealed wire terminal includes a seal member supporting the cables and sealing the through-hole. Thus, the automatic transmission and the electronic control unit can be combined before mounting on a vehicle.

An electronic control unit (ECU) and a position detection unit are disposed in separate chambers formed in a case. Two switch portions are separately disposed on opposite sides of a movable member of the position detection unit, thus reducing the size of the unit. The signal-related circuit that needs to be connected to the ECU for signal transmission and the drive circuit, for starting the starter motor and turning on the reverse lamps, that does not need the connection to the ECU for signal transmission, are separately disposed on the opposite sides of the movable member, that is, on the case side and a first cover side. The drive circuit is completely separated from the signal-related circuit and the ECU, thus preventing the drive circuit from electrically interfering with the signal-related circuit or the ECU.

A lockup clutch for torque converter which prevents engaging and disengaging shock when a transmission torque suddenly changes, includes a lockup clutch assembly, a lockup clutch piston operating the lockup clutch assembly, and a damper device disposed between the lockup clutch piston and an output member for absorbing changes of transmission torque occurring in association with the operation of the lockup clutch assembly. The lockup clutch piston is made of steel and has a thermally treated portion placed at a surface in contact with springs of the damper device wherein the thermally treated portion is hardened by rapid local melting with high density energy radiation such as electron beam followed by rapid cooling.
摘要:
A transport arm of a semiconductor substrate transport apparatus carries a semiconductor substrate both into and out of a semiconductor substrate processing chamber in each operation of the transport arm, shortening operation time and prolonging the operating life of the apparatus. First and second arms are rotatably mounted at the leading end of an extensible arm of the semiconductor substrate transport apparatus, each including a substrate holding portion at the leading end for supporting a semiconductor substrate. The first and second arms are turned by an arm driving device while in the semiconductor substrate processing chamber.
