摘要:
A suspension device for front wheels in automotive vehicles having front drive shafts of mutually different shaft length, in which unbalanced rotatory moment to be imparted to the king pin means at the left and right sides of the wheels caused by a difference in the angles of inclination at the left and right drive shafts is compensated by providing a difference in the center offset quantities at both left and right wheels.
摘要:
The coating composition is prepared by partial co-hydrolysis and co-condensation of a mixture comprising an organotrialkoxysilane or its combination with a tetraalkoxysilane, a fluoroalkylalkoxysilane and a hydroxy-endblocked diorganopolysiloxane in the presence of an acid catalyst. The organopolysiloxanes thus prepared are suitable for coating plastic surfaces to produce a coating on the surfaces, the cured coating film having hardness as well as flexibility sufficient to ensure a very strong resistance to swelling, dissolution or corrosion by attacks of solvents and chemicals.

A leak detecting system for a transpiration purge system including a fuel tank 1 and a canister 13 includes a jet pump 8, which leads the atmosphere into the fuel tank 1 using a return flow of excess fuel of fuel pumped to an internal combustion engine, internal pressure measuring means 15, and fuel volume detecting means 18. After supplying the air from pressurizing means for a predetermined time, the leak detecting system judges that a leak is present when a holding pressure measurement value in a state in which the transpiration purge system is closed is lower than a decompression calculation value calculated from a pressurization measurement value, an air volume, and a leak hole diameter.
摘要:
In a memory cell array, a plurality of memory cells having ferroelectric capacitors are arranged. A plurality of sense amplifier circuits amplifies the potential of the bit line of each memory cell. A column decoder outputs activation signals to activate the sense amplifier circuits. Timing adjusting circuits have a ferroelectric capacitor for timing adjustment in transmitting the activation signals output from the column decoder to the sense amplifier circuits.
摘要:
A fuel supply apparatus having a fuel pressure regulator (60) for regulating the pressure of fuel discharged from a fuel pump (4) to a predetermined pressure, the fuel pressure regulator (60) including: a first chamber (62), formed in a case (61), into which fuel discharged from the fuel pump (4) flows, and a second chamber (63), into which the fuel flows via the first chamber (62); a fuel limiting means (64) disposed between the first chamber (62) and the second chamber (63), for limiting fuel flowing from the first chamber (62) into the second chamber (63); a pilot valve unit (65) having a passageway for opening to discharge fuel tank (2), when the fuel pressure in the second chamber (63) is more than a first set pressure (Pp); and a main valve unit (66) having a passageway for opening to discharge fuel into the fuel tank (2) when the fuel pressure in the first chamber (62) is equal to a second set pressure (Pm) between the first set pressure (Pp) and the predetermined pressure (Pi), whereby, in cases where returning flow volume drops, the pressure of the fuel delivered under pressure to the injector does not drop.
摘要:
A fuel supply system in which a fuel filter has a large filtration area is obtained without increasing an outer diameter of the fuel supply system and an outer diameter of a tank hole through which a pump module is inserted in a fuel tank. The fuel supply system comprises a fuel pump 5, a fuel pressure regulator 9 for regulating pressure of fuel, and a fuel filter 6 having a hollow cylindrical filter case 7for filtering the fuel, and in which the filter case 7 has a holding hole 7a for holding the fuel pump, a center line CL1 of the holding hole is eccentric with respect to a center line CL2 of the filter case 7 by a predetermined distance M, and a first enlarged space portion S1 in which fuel system parts such as fuel pressure regulator 9 are accommodated is formed at a part surrounded by an outer circumferential portion of the fuel pump 5 and an outer circumferential portion of the filter case 7.
