Title: Detector of metal
Inventor: TARUI MASAHIRO
IPC: G01V3/08
Filed: 1983-07-22
Abstract: PURPOSE:To detect a metal in high sensitivity with a simple detecting circuit by arranging >= a pair of hall devices to which a bias current having the same frequency as an alternating field is supplied, in an advancing direction of a body to be inspected in said magnetic field. CONSTITUTION:An AC source 13 supplies alternating current to the hall devices 11a-11b through an alternating field generator 10 and phase shifters 14, 15. The bias current of each hall device is in-phase and anti-phase at the devices 11a, 11b respectively against the magnetic field, and is shifted by 90 deg. and 270 deg. at the devices 12a, 12b. If magnetic metal is contained in the body W to be inspected, a difference occurs in the outputs of the devices 11a, 11b, and an output from an arithmetic amplifier 16B is compared with a fixed voltage by a comparator 18B through a low-pass filter 17B to detect the metal. If nonmagnetic metal is contained in the body W, since the phase of the magnetic field is varied and the phases of the output voltages of the devices 12a, 12b are varied, said metal can be detected similarly by adding these output.

Title: Lifting table holding mechanism
Inventor: ONO TAKASHI
IPC: E04H4/00
Filed: 1993-06-03
Abstract: PURPOSE:To hold a lifting table automatically at an elevated position by a lifting table holding mechanism comprising an upper and a lower member pivotally joined to the lifting table and a fixed table, a control means for controlling the turning of the upper and the lower member in one direction, and a joint moving means for horizontally moving the joint of the upper and the lower member. CONSTITUTION:When a lifting table 3 is elevated by a lifting means, a joint pin 5a is positioned at a small distance from a vertical line V on the side opposite the side of a stopper bracket 10 with respect to the vertical line V. Then, the operating rod of a cylinder actuator 12 is retracted to turn a lower member 4 clockwise to shift the joint pin 5a to the other side; consequently, an upper member 11 is displaced by a small distance beta and the side surface 1a of the upper member 1 comes into contact with the stopper bracket 10 to hold the members 1 and 4 in positions slightly tilted toward the stopper bracket 10. The lifting table 3 is held at the elevated position even if load L is exerted on the lifting table 3 because the stopper bracket 10 and the members 1 and 4 bear the load L. The cylinder actuator 12 need not apply any force to the lower member 4, which saves power.

Abstract: PURPOSE:To reduce the size of a swivel joint by a method wherein cylinders for tilt, an angle, and a dozer are controlled through a single control valve. CONSTITUTION:When a running two-speed switch 30', a switch 45 for tilt, and a switch 46 for an angle are all switched OFF, an electromagnetic switching valve 29' for running two-speed is brought into one-speed in a tank communicating oil passage position during running. Further, since an electromagnetic switching valve 40 for outputting a tilt angle pilot pressure is in a cutoff oil passage position, a three-position pilot switching valve 36 is located in a dozer control position. In which case, when a control valve 44 is operated as a running stop state is produced or a on-speed running is carried out, a main pressure oil from a pump 25 is fed to a dozer cylinder 5 through the positions of a valve 44, a swivel joint 48, and a switching valve 36. When only the switch 45 is brought into an ON-state, the switching valve 36 is switched to a tilt control position through the switching valve 40 and a switching valve 38 for a low pressure and a middle pressure pilot pressure by means of a low pilot pressure.
