Abstract: An automatic transmission control apparatus includes a continuously variable transmission (CVT) which, in turn, includes a primary pulley, a secondary pulley, a belt stretched between the primary pulley and the secondary pulley. The control apparatus further includes a pinching pressure generator for generating a pinching pressure on the belt, a travel environment all detector for detecting the travel environment of a vehicle, a torque variation estimator for estimating the transmission torque variation during travel, and a pinching pressure changer for changing the pinching pressure based on the estimation. The pinching pressure is prevented from constantly increasing because the transmission torque variation during travel is estimated, and the pinching pressure for the belt is changed based on the estimation. Accordingly, the torque transmission efficiency can be increased, and the fuel efficiency can thus be improved.

Abstract: A method and apparatus for continuously drawing an elongated stock permit plural types of drawings within a narrower area, by a series of automated steps and permit easy adjustment of the distance between a front end position of a plug and an outlet position of a die. A holding member with plural types of dies is mounted at a central position relative to reciprocation of an elongated stock. When the elongated stock is to be moved from one side to the opposite side of the die holding member, it is passed through an elongated stock passage, not through the dies, while when the elongated stock is to be moved from the opposite side to the one side of the die holding member, it is passed through one of the plural dies. The elongated stock is reciprocated plural times between the one side and the opposite side of the die holding member and the die holding member is moved at each passage of the elongated stock through a die to change the type of die.

Abstract: A motor 12 includes a cylindrical rotor 20, a stator 19 arranged at a predetermined distance from an outer periphery of the rotor 20, and a position sensor 23 for detecting a rotational position of the rotor 20, wherein the stator 19 includes a stator core 19a and a plurality of stator windings 19b arranged along a circumferential direction of the stator core 19a at substantially equal distances from one another. A shield plate 26 for shielding magnetic flux from the stator windings 19b to the position sensor 23 is mounted against the stator core 19a. Magnetic flux from the stator windings pass through a closed loop starting from the stator windings 19b through the stator core 19a and the shield plate 26 and back to the stator windings to prevent the magnetic flux leakage from the stator windings 19b from flowing to another member. With this arrangement, the magnetic flux leakage from the stator windings does not affect the position sensor (magnetic sensor) which detects the rotational position of the rotor.

Abstract: A hydraulic accumulator is equipped with a novel shut-off valve. The shut off-valve includes a valve body having a cylindrical hollow with a valve seat surrounding one end. The main piston including a piston head has a central opening and is slidably mounted within the cylindrical hollow of the valve body. A poppet valve has a valve head which mates with the valve seat and a valve stem which extends through the central opening of the piston to guide axial movement of the poppet valve relative to the piston. A spring is mounted between the valve head and the main piston head for urging the valve head away from the piston head. A control valve moves the piston relative to the valve body between open and closed positions responsive to signals from a computer which signals valve closing upon determination that flow rate through the valve exceeds a maximum period.

Abstract: A compact apparatus and a method for generating wavelength-tunable short optical pulses, which apparatus and method can change the wavelength of generated pulses without adjustment of an optical system and enable generation of ideal femtosecond soliton pulses. The apparatus includes a short-optical-pulse source, an optical characteristic regulation unit for regulating characteristics of light output from the short-optical-pulse source, and an optical fiber for receiving input pulses from the optical characteristic regulation unit and for changing the wavelength of output pulses linearly. Short optical pulses are input to the optical fiber, so that new soliton pulses are generated in the optical fiber due to its nonlinear effect. Further, the nonlinear effect enables the wavelength of the soliton pulses to shift linearly in accordance with the intensity of input light.

Abstract: At the time of starting a vehicle, the torque capacity of a friction engagement element is made less than the torque capacity of a continuously variable transmission by setting a ratio between the pressure-receiving area of a control oil chamber (77a) of a garage shift control valve (77) and the pressure-receiving area of a feedback chamber (77d) of the valve, and a ratio between the pressure-receiving area of a control oil chamber (73a) of a secondary sheave control valve 73 and the pressure-receiving area of a feedback chamber 73d of the valve. This allows a control based on a single linear solenoid valve SLT although the control is for eliminating slip of a belt of the continuously variable transmission. Therefore, the construction of the oil pressure control apparatus is simplified so that the size and cost thereof can be reduced.

Abstract: The present invention relates to a hinge providing a specified braking force against pivotal motion between two hinged flaps. The hinge includes a bearing body, which has, at its exterior, mountings for a first flap and also a wear-resistant inner surface having slider catches at positions spaced by a specified angle on the same circumference of the inner surface. The hinge also has a shaft with a mounting at one end for a second flap. The shaft is mounted in the bearing body in a manner allowing relative turning, and also has a spring housing hole opening at its outer surface along an axis crossing at a right angle with its longitudinal axis. While turning, a coil spring, which is inserted into the spring housing hole, biases a slider radially outward from the spring housing hole.
