摘要:
An actinic energy ray curable adhesive contains a urethane resin (D) and a epoxy resin (E). The urethane resin (D) is prepared by reacting a diol ingredient (A1) having no (meth)acryloyl group, an optional diol ingredient (A2) having no (meth)acryloyl group, no carbonate structure and no alicyclic structure, a polyol ingredient (B) having a (meth)acryloyl group and two or more hydroxyl groups in a molecule, and a polyisocyanate ingredient (C) together. The ingredient (A1) is selected from a diol (a1) having a carbonate structure and an alicyclic structure in a molecule, a combination of a diol (a2) having no alicyclic structure but having a carbonate structure, and a diol (a3) having no carbonate structure but having an alicyclic structure, and a combination of a diol (a1) and at least one of the diol (a2) and the diol (a3).

A speed change control system for an automatic transmission for motor vehicles having a planetary gear mechanism and a brake band for altering the transmission ratio. The system is to tighten gradually the brake band. The system comprises a servo-piston, a piston rod secured to the servo-piston and to the brake band, and an accumulator piston axially slidably disposed in the bore of the servo-piston. The servo-piston is biased by a first spring for returning the servo-piston for releasing the brake band, and the accumulator piston is biased by a second spring. Apply side and release side oil chambers are formed on opposite sides of the servo-piston, and an accumulator oil chamber is formed by the accumulator piston in the bore. Pressure oil is applied to the apply side oil chamber, so that the servo-piston moves in a brake band engagement direction against the first spring. After that, the accumulator piston moves a predetermined stroke against the second spring. Thereafter, the accumulator piston engages with the servo-piston, so that both pistons move together for tightening the brake band.
摘要:
An automatic transmission with a torque converter for use with an internal combustion engine in which the ignition timing is changed over to an advancing timing region or a retarding timing region in response to the operating condition of the engine. Two different speed shifting characteristics are provided in response to whether the ignition timing is in the advancing timing region or in the retarding timing region. In addition, the two speed shifting characteristics are changed over to each other according to the two ignition timing characteristics.
摘要:
A system for controlling a power transmission of a four-wheel drive vehicle powered by an engine. The system is provided with a transmission for transmitting a power of the engine to main wheels, a clutch for selectively transmitting the power to auxiliary wheels, a vehicle speed sensor for sensing the speed of the vehicle and for producing a vehicle speed signal dependent on the speed, a steering angle sensor for sensing the steering angle of the vehicle and for producing a steering angle signal dependent on the steering angle. A control circuit is provided to compare the vehicle speed signal and steering angle signal with reference values and judge whether the condition is in the range of conditions causing tight corner braking and to produce a clutch signal. A switch is responsive to the clutch signal for disengaging the clutch, whereby the four-wheel drive is changed to the two-wheel drive.

A power transmission control system for a four-wheel drive vehicle powered by an engine has a transmission for transmitting the power of the engine to main driving wheels of the four-wheel drive vehicle, and a clutch for transmitting the power to auxiliary driving wheels. A hydraulic circuit for operating the clutch and a solenoid operated valve are provided for operating the clutch.Speed sensors are provided for detecting speeds of the main and auxiliary driving wheels in order to detect the slipping of wheels and vehicle speed.A steering angle is sensed for detecting a large steering angle. An electric circuit is provided to respond to the output of the speed sensors at slipping for engaging the clutch and to respond to large steering angle at low vehicle speed for disengaging the clutch for providing two-wheel driving.
