IPC: G01N27/72
Filed: 1995-02-01
Abstract: PURPOSE: To obtain a metal detection apparatus by which the occurrence frequency of a malfunction is reduced without increasing costs by a method wherein a metal detection means is operated for only a definite time since an object, to be detected, being conveyed has been recognized on the upstream side of the metal detection means. CONSTITUTION: In a metal detection means 1, an upper-part head 3 in which a receiving coil is housed and a lower-part head 5 in which a transmitting coil is housed are fixed by keeping a definite distance by means of a liner 6. One pair of photo-sensors 4 which recognize an object, to be detected, being conveyed are mounted on, and attached to, the upstream side of the liner 6. A lever 16 by which the object 9, to be detected, in which a metal has been detected, is discharged to the outside of a belt conveyor 10 is installed on the downstream side of the detection means 1. A detection-effective-time timer part, a conveyor speed data part, a set data part, a discharge-delay timer part and the like are installed in a RAM for a control part installed inside a control box 8.  The tip part of the object 9 to be detected operates the discharge lever 16 while a point of time recognized by the sensors 4 is used as a reference. As a result, the object, to be detected, in which the metal has been added can be excluded accurately irrespective of the added position and the size of the metal 17.

Title: Non-contact end face type mechanical seal
Inventor: SHIMIZU TADAYUKI
IPC: F16J15/34
Filed: 1989-03-03
Abstract: PURPOSE:To secure non-contact between seal end faces even at low rotating speed or generation of outside high distortion on seal end faces by forming two kinds of spiral grooves on the seal end face so that they are different as to length, width, and depth, and arranged from sealing fluid side peripheral edge as the start point. CONSTITUTION:At rotation of a rotating shaft A, as a first and second spiral grooves 11..., 12... are formed, from the outer circumference side to the inner circumference side of a rotating seal ring 1, into turning spirals in the reverse direction against rotation of the shaft A, sealing fluid smoothly flows in the grooves 11..., 21.... Hereafter, the rotating seal ring 1 and stationary seal ring 4 become non-contact at their end faces by spreading action, and as the grooves 21... are wide and extend only up to 40% of the width (b) of the seal face, dynamic pressure surely generates even at outside high distortion of the seal end face. Further, at low rotating speed, the static pressure effect due to the sealing fluid in the grooves 11..., 12... assists the dynamic pressure effect due to the sealing fluid invaded in the grooves 21, hence non-contact condition between the seal end faces can be secured.
