Abstract: PURPOSE:To eliminate useless controls by configurating a suspension device with a ground clearance adjustment mechanism in such a manner that the adjustment of ground control is not permitted when the spring constant is hard or is to be hardened while the spring constant is adjustable. CONSTITUTION:Signals from a ground clearance sensor 24, a car speed sensor 26, a steering handle angular acceleration sensor 28, an acceleration sensor 30, and an accel opening sensor 32 are inputted into CPU34 permitting a motor 36 and a compressor 38 to be operated.

Also the spring constant can be softened by connecting both the reservoirs 20a and 20b with an actuator 46 operated, and can be hardened with both the reservoirs disconnected. In this case, the spring constant control actuator 46 is operated by CPU34 when the spring constant is hard, and a ground clearance adjust mechanism 36 and 40 is operated by CPU when the spring constant is soft and no hardening is required. This configuration eliminates useless controls.

Abstract: PURPOSE:To attain the fine adjustment and high-speed cutting job in simple constitution and at the same time to facilitate the change of the noncircular data by reading out the commanded voltage and corrected voltage data corresponding to the work rotational angle, and controlling the displacement of an additional shaft for cutting byte. CONSTITUTION:A single rotation signal produced from a synchronizing signal generator 1 and the serial pulses are supplied to a noncircular cutting work 2. Then the angle of the work 2 is applied to a processor 9 from an angle position generator 3. Thus a command function part 7 of the processor 9 reads out the commanded voltage data corresponding to the rotational angle of a memory 6 and controls the displacement of an additional shaft of a cutting tool 5 via a drive part 10 and an actuator 11. In case the rotational angle has no change, the displacement value of the additional shaft obtained by the actuator 11 and a displacement detector 4 is fed back. Then the command displacement data on the memory 6 and the corrected voltage data corresponding to the temperature, etc., accordant with an error against the feedback displacement value are read out of the memory 6 by the processor 9 via a corrected function part 8 and supplied to the part 10. Thus it is possible to attain the fine adjustment and the high-speed cutting jobs in a simple constitution requiring no cam for stylus and also to facilitate the change of the noncircular data.

Title: Apparatus and method for mounting conductive balls
Inventor: ARIKADO KAZUO
IPC: B23P21/00
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To reliably detect the pick up error of conductive balls when the balls in a feeder are picked up by vacuum to suction holes at the lower face of a vacuum head and mounted on a work. SOLUTION: With moving a vacuum head 11 to a substrate, a light is irradiated on the head 11 from a light source 40. If an optical sensor 35 detects the leaking light, some suction hole 33 has not sucked the ball and this is judged to be a pick up error. The light passing near the inner wall 31a of the head 11 is reflected at a light reflective part a of the inner wall 31a toward a collector element 34 and applied to the sensor 35. Thus the pick up error of the suction holes 33 near the inner wall 31a can be reliably detected.
