摘要:
Selective connection of a first pair of output openings or a second pair of output openings opening in different directions with pipe fittings and closing of unused openings with closing plugs are facilitated by the use of a, substantially U-shaped removable stopper pin whose legs are inserted into the corresponding legs of fit-in grooves on both sides of the output openings and engaged with engaging grooves around the periphery of the pipe fittings and closing plugs.

A safe, double solenoid type electromagnetic valve which can be used as a single solenoid type electromagnetic valve and in which a main valve member does not change from one change-over position to another even when electric power is supplied to two pilot valves at the same time. A first piston is disposed at one end of the main valve member while second and third pistons are disposed at the opposite end. The first and second pistons have the same diameter while the third piston is smaller in diameter than the first two. Two solenoid mechanisms are provided for making a pilot fluid operate on the first piston as well as the second and third pistons. A change over device is also provided which is able to change over the operation from a first situation where the pilot fluid is allowed to operate on both the second and third pistons to a second situation wherein the pilot fluid is allowed to work only on the third piston.

The present invention realizes an efficient superscalar instruction issue and low power consumption at an instruction set including instructions with prefixes. An instruction fetch unit is adopted which determines whether an instruction code is of a prefix code or an instruction code other than it, and outputs the result of determination and the 16-bit instruction code. Along with it, decoders each of which decodes the instruction code, based on the result of determination, and decoders each of which decodes the prefix code, are disposed separately. Further, a prefix is supplied to each decoder prior to a fixed-length instruction code like 16 bits modified with it. A fixed-length instruction code following the prefix code is supplied to each decoder of the same pipeline as the decoder for the prefix code.

A starter for an internal combustion engine includes a power transmission mechanism. The power transmission mechanism has an outer race plate fastened to a crankshaft, and a ring gear coupled to a rotational shaft of an electric motor for starting the engine. The power transmission mechanism further has a one-way clutch for permitting torque transmission only from the ring gear to the outer race plate, and two sealing members. Lubricant is supplied from the cylinder block to the interior of the power transmission mechanism for lubricating the power transmission mechanism. The outer race plate has a groove on its contact surface of a contact portion between the crankshaft and the outer race plate. The groove extends in the entire circumferential direction of the crankshaft. This maintains the coupling strength between the outer race plate and the crankshaft, while enhancing the sealing performance of the power transmission mechanism.
