Abstract: A transmission is provided having a dual clutch, to achieve torque flow through a countershaft gearing arrangement. The countershaft gearing arrangement includes a plurality of co-planar gear sets having gears that are selectively connectable to a plurality of countershafts. At least one transfer gear set transfers torque from the counter shafts to an output shaft. The output shaft is connected to a final drive unit that has a final drive unit output shaft that is transverse to an input member connected at one end to a torque converter and at the other end to the dual clutch.

Abstract: A turbine combustion chamber is provided with deflectors on the cold side generating vortices in a secondary gas flow into the chamber, thereby confining the flame front under variable operating conditions and cooling the chamber walls. The high-speed cantilever shaft has a longitudinal duct and an array of fine orifices in the wall of the shaft for directing pressurized oil jets that impinge on the shaft bearings with little relative speed to increasing wetting of the bearing components. Oil is supplied to the duct by means of a positive-displacement pump directly driven by the output shaft. The pump output pressure is monitored to signal the end of the start-up sequence when the turbine reaches sufficient speed. The turbo-engine further includes devices for decoupling vibrations between the three systems thereof, including a loosely-mounted removable spline pivotable at both ends for coupling the high-speed shaft to the step-down gearbox.
Abstract: There is provided a method for producing a silver powder having excellent dispersibility and capable of forming a paste which do not form suspended matters by phase separation and which is printed on a substrate to form a film having a uniform thickness. In this method, an alkali or a complexing agent is added to an aqueous silver salt containing solution to form a silver oxide containing slurry or an aqueous silver complex salt containing solution. After or before silver particles are deposited by reduction by adding a reducing agent to the silver oxide containing slurry or aqueous silver complex salt containing solution while stirring it, at least one chelating agent selected from the group consisting of compounds having an azole structure, dicarboxylic acids, hydroxy carboxylic acids and salts thereof is added to a silver power containing slurry solution as a dispersing agent.
Abstract: An electric power apparatus and a power transmitting apparatus of an electric vehicle are each constructed as a unit structure to improve the overall range and reliability of the electric vehicle. In the electric vehicle including, as a power system, a battery power supply, a motor, and a controller for controlling rotation of the motor, an electric power unit comprises a plurality of storage cells making up the battery power supply, a case housing the storage cells, a motor driving circuit and a charger both mounted on the case, a plate substrate covering the storage cells, and sockets for connecting respective terminals of the storage cells, the motor driving circuit and the charger.
Abstract: A jaw clutch coupling mechanism in which spline grooves serving as ball drop-in portions of the clutch are provided with a semi-spherical ball support recess to be engaged with a steel ball by way of linear or surface contact for enhancing the strength of the jaw clutch. A stopper is provided in the shift lever link mechanism to hold the shift lever securely in the forward, neutral or reverse position, and a shock absorber is provided in association with the shifter arm of the jaw clutch to dampen the shocks of engagement of the clutch, ensuring a better feeling in shift lever operations.
Abstract: A drive device for a two-shaft extruding machine whereby the directions of relative rotation of the two screw shafts of the machine can be rapidly changed without having to manually change a gear. The drive device includes a first shaft, a second shaft disposed coaxially with the first screw shaft and rotatable integrally therewith, a third shaft disposed coaxially with the intermediate shaft and rotatable integrally therewith, a first gear rotatable integrally with the first shaft, a second gear rotatable integrally with the second shaft and meshed with the first gear, a third gear rotatably supported on the third shaft and meshed with the first gear, and a fourth gear rotatable integrally with the second shaft and a fifth gear rotatably supported on the third shaft and meshed with the fourth gear. A claw clutch is provided for rotatably coupling a selected one of the third and fifth gear to the third shaft.
Abstract: A zero backlash shiftable transmission includes an input shaft and an output shaft coupled through a gear network that is preloaded with a spring arrangement to eliminate the backlash from the engaged surfaces of the gear teeth. There are three positions and no neutral. In the first position a tapered clutch arrangement engages the input shaft directly with the output shaft. In the second or shift position, the clutch engages both the input shaft and the output shaft while the transmission is slowed or stopped for shifting. In the third position, the clutch engages the input shaft with the output shaft through the preloaded gear network. The tapered clutch arrangement provides locked clutch coupling in the first and third positions and provides tolerance for shifting without completely releasing either the input shaft or the output shaft in the shift position.
Abstract: A modified manual synchronized automobile transmission for use in racing cars eliminates second gear and imparts initial rotary motion from the engine to the output shaft via a by-pass of gearing including a normally disengaged clutch. Brief engagement of the clutch causes power to feed through this by-pass gear train for just so long as the clutch is engaged and, depending on the setting of interlocked collar selector forks, will cause reverse motion of forward motion in low gear. When the car is in racing modality and moving forward in low gear, it is then possible, without further reference to the clutch, to place the main gear train in direct drive, linking the main drive shaft of the motor and the output shaft of the transmission to achieve "lock up". The invention obviates the need for a flywheel. The invention may be practiced by physical modification of an existing manual synchronized transmission.
Abstract: This invention provides an improved automotive transmission, particularly for highway trucks, wherein an overdrive condition of the transmission may be obtained by extension of the normal H-shaped shifting pattern of the gear shift lever. A direct drive condition of the transmission is obtained when the gear shift lever is in the forward position of the last lateral leg of an extended H shift pattern and the overdrive condition is obtained when the gear shift lever is in the rearward position of such last leg of the shifting pattern, thus requiring no unusual shifting movements on the part of the operator to effect the conversion of the transmission into the overdrive condition.
