Abstract: PURPOSE:To prevent oscillation at the time of backing up a slope so as to enhance travelling by actuating the actuator for operating of a damping force adjusting shock absorber so as to increase damping force when a vehicle goes back on an upward slope. CONSTITUTION:When a slope sensor M4 detects that a vehicle is on an upward slope and a reverse switch M5 detects that the shift position of a gearbox is in a reverse position, a damping force control mean M6 outputs a control signal to an actuator M2 based on these detected signals so as to increase the damping force of a shock absorber M3. With this arrangement, the actuator M2 increases the damping force of the shock absorber M3. With this structure, the vehicle can travel stably without generating oscillation at the time of backing up a slope.

Abstract: PURPOSE:To simplify the circuit constitution and to attain inexpensive configuration by employing a common level frequency detection circuit of a MODEM to detect a DT, a BT and of a telephone set side to detect a CI when a telephone line is changed over to the telephone set side or the MODEM side. CONSTITUTION:For example, in the case of automatic transmission, a control section 24 selects a CML relay 1 to the position of a facsimile equipment. Then an input to a level frequency detection circuit 12 is thrown to the position of the facsimile equipment so as to detect a DT/BT by using a changeover switch 11. In the case of the automatic reception, the changeover switch 11 is thrown to the position such that the input of the level frequency detection circuit 12 is thrown to the position of the telephone set. The control section 24 throws the CML relay 1 to the position of the facsimile equipment when the CI is detected. Thus, the one level frequency detection circuit 12 detect the DT/BT and the CI by switching the changeover switch 11 in response to the CML relay 1.

Abstract: PROBLEM TO BE SOLVED: To surely and inexpensively perform fine circular arc machining for a gear side face by arranging a buff drive shaft and a workpiece drive shaft nearly perpendicularly to each other, inclining the workpiece drive shaft upward from a horizontal line and constituting a workpiece holder of a flexible member or a member in which friction easily occurs. SOLUTION: A buff drive shaft 9 is protruded from a drive motor in a lateral direction. A buff 1 composed of a brush or the like is fixed in its tip. A workpiece drive shaft 6 for driving a workpiece holder 2 against the buff drive shaft 9 arranged horizontally is supported by an angle (a) in which the workpiece holder 2 is slight upward from a horizontal line. Since the workpiece holder 2 is made of a flexible material or a member having large friction resistance, when the workpiece holder 2 is rotated, the inner periphery of the workpiece holder 2 and an internal gear 3 are rotated. Since a contact area between the workpiece holder 2 and the internal gear 3 is small, a frictional force rotation is realized.
