Abstract: PURPOSE:To perform a proper driving distribution all the time as well as to make improvements in travelability, by making an estimated value in a speed difference between front and rear wheels a criterion, while letting a controller perform its control over such a driving force distribution as causing an actual value to get nearer to this estimated value. CONSTITUTION:As a transfer to be interposingly installed in the midway in a driving force transmission system for front and rear wheels 1 and 2, there is provided with a variable torque clutch 4 capable of altering a driving force distribution for these front and rear wheels 1 and 2 with controlling operation of an actuator 3. In addition, there are provided with speed sensors 5 and 6 detecting a revolving speed in a driving shaft system from this clutch 4 to these front and rear wheels 1 and 2, a steering angle sensor 7 and a car speed sensor 8. And in a controlling device 9, a front-rear shaft revolving speed difference is estimated from a steering angle signal (a) by the steering sensor 7 and a car speed signal (b) by the car speed sensor 8, making this controlling device generate such a control signal as causing an actual front-rear shaft revolving speed difference by revolving speed signals (c) and (d) out of both speed sensors 5 and 6 to get nearer to this estimated value, thus the actuator 3 is controlled.

Filed: 1985-04-26
Abstract: PURPOSE:Silicon carbide is used for the (chlorine-hydrogen) burner and silane or halogenated silane is blown into the flame to readily permit the production of silicon higher in purity than conventional products. CONSTITUTION:The precipitation of silicon is effected by blowing chlorine and hydrogen into a reactor to form a burning flame and feeding silane and/or halogenated silane into the flame where the burner is made of silicon carbide. Further, use of the reactor and other auxiliary parts made of silicon carbide is preferred, because silicon of high purity is readily obtained. Hydrogen is used in a stoichiometrically excessive amount based on the total of the silane and/or halogenated silane and chlorine.

IPC: B29C65/52
Filed: 1985-04-26
Abstract: PURPOSE:To carry out the bonding of a glass substrate with an adhesive layer having uniform thickness, by supplying an adhesive to the surface of a glass substrate placed on a table, placing another glass substrate on the adhesive and rotating the table to effect the spreading of the adhesive layer by the centrifugal force. CONSTITUTION:A glass substrate 22 to be bonded is placed on a spinner head 21 (a substrate table) facing the bonding surface upward. An adhesive 23 is supplied to the surface of the substrate 22 e.g. by dripping, and another glass substrate 24 is placed on the substrate 22 facing the bonding surface downward. The spinner head 21 is rotated at a rotational speed of preferably 1,000-3,000rpm to spread the adhesive 23 radially by the centrifugal force. A uniform adhesive layer can be formed by this procedure to give a bonded glass substrate having high flatness.

IPC: G02B23/26
Filed: 1984-05-07
Abstract: PURPOSE:To easily adjust the position of an ocular lens in an optical-axis direction by moving the ocular lens in the optical-axis direction by a diopter adjustment and moving the ocular lens to a reference position when an optical adapter is fitted. CONSTITUTION:When a diopter adjusting ring 41 is rotated, a cam tube 32 rotates together and an interlocking part 30a, i.e. an intermediate cylinder 29 and an ocular lens tube 28 move in one body according to the inclination of the cam surface 40. Then when the optical adapter is mounted on an optical adapter fitting ring 26, only the lens tube 28 moves back according to the relation between a straight guide groove 34 and a control part 30b because the backward movement of the intermediate tube 29 is controlled by the cam surface 40 of the cam tube 32 where a motion part 30a abuts if the lens tube 28 is before the reference position. On the other hand, when the lens tube 28 is behind the reference position, the lens tube 28 and intermediate tube 29 move forth through the cam opening 33 of the cam tube 32. When the optical adapter is detached, the lens tube 28 returns to the state before the optical adapter is attached with forces of the 1st and the 2nd compression coil springs 35 and 36.

IPC: H02P27/06
Filed: 1987-04-15
Abstract: PURPOSE:To suppress the rush current of load current, by controlling the load current at the time point of a peak load to be constant. CONSTITUTION:In case that a press machine 14 is driven and press working is performed, and when the pressure of the press machine 14 is worked, then a rotational speed is reduced. Along with this reduction, the load current IL of an induction motor 46 is increased. The increment of the load current IL is detected by a current detector 16, and when the detected value exceeds a previously set rating value, then by a current regulator 48, the frequency of control signal fed to a power converter 44 is lowered. As a result, the power converter 44 is pulse-width-modulation-controlled, and the load current I1 is limited to a constant value.
