Filed: 1985-12-09
Abstract: PURPOSE:To attain miniaturization and cost reduction, by a method wherein the memory content of a first memory means is replaced with the count value of a flaw signal detection means at each time when a probe is changed over in synchronous relation to pulse repeating frequency and the peak value of the flaw signal stored by a second memory means is renewed.

A second memory means 11 stores a flaw signal having a max. peak value with respect to each of a plurality of probes. At each time when the probes are changed over in synchronous relation to pulse repeating frequency, the memory content of the first memory means is replaced with the count value of the flaw signal detection means. When the peak value of the detected flaw signal is larger than that of the flaw signal stored by the second memory means, the peak value of the latter is renewed and, further, a digital/analogue converter 14 outputs the flaw signal stored by the second memory means while converting the same to an analogue signal.

Title: Curve conveyor
Inventor: TANAKA KIYOOMI
IPC: B65G15/02
Filed: 1994-11-11
Abstract: PURPOSE: To reduce the driving resistance of a curve conveyor, and to prolong the lifetime by forming a pinching rotor fitting member of a belt holding device from an elastic body so that the pinching rotating body can follow the snaking of a carrying belt. CONSTITUTION: A thick part 20 formed in the peripheral edge of a loop-like carrying belt 2 is held by multiple belt holding devices 3 arranged along the peripheral edge of the carrying belt 2 so as to hinder the inward movement of the carrying belt 2. In this conveyor, a main body 30, to which pinching rotors 31, 32, 33 are fitted, is made of an elastic body. In the case where the carrying belt 2 generates the meander, the external force with the meander is applied to the belt holding devices 3, and the carrying belt 2 is moved inside, resisting the pinching force of the rotors 31, 33 and 32, 33. At this stage, the main body 30 is elastically deformed and the rotor 31 or 32 follows the meander of the carrying belt 2 and displaced in relation to the rotor 33.  As a result, driving resistance of the curve conveyor is reduced, and the abrasion of the thick part 20 is reduced so as to prolong the lifetime.
