Title: Device for cutting electronic component from lead frame
Inventor: TAKAMI KATSUHIRO
IPC: H01L23/50
Filed: 1989-10-13
Abstract: PURPOSE:To make it possible to cut off selectively an arbitrary electronic component from a lead frame by a method wherein each cutter head is provided with an upper blade for cutting use to a lower blade for cutting use and an arbitrary cutter head out of the cutter heads is moved up and down during the forward movement of a reciprocating head. CONSTITUTION:A reciprocating head 5 is made to perform a forward movement at the same speed as the traveling speed of a lead frame A in the transfer direction of the frame A, that is, by a prescribed length along with the frame A and thereafter, is made to perform a return to its former position and is made to repeat this reciprocation. Whereby cutter heads 36 to 41 provided at this head 5 are also made to perform a forward movement by a prescribed length along with the frame A like the head 5 and thereafter, are made to perform a return to their positions and are made to repeat this reciprocation. Accordingly, the cutter heads 36 to 41 provided at the head 5 are made to perform a descent during the forward movement of the head 5. Thereby, electronic components which are continuously provided on the frame A can be cut off from the frame A being transferred continuously by upper blades 44 to 49 for cutting use provided at the cutter heads 36 to 41 and a lower blade 11 for cutting use.

IPC: G01N11/14
Filed: 1993-10-27
Abstract: PURPOSE:To obtain a fine evaluation measure which can estimate the workability of unvalcanized rubber by a method wherein the countraction torque of the unvulcanized rubber is stored as digital data at every prescribed sampling time, the stored data is analyzed and the characteristic value of the Mooney voscosity is found. CONSTITUTION:For example, a correlationship between the quality of the dispersion state of a filler such as carbon black or the like and the characteristic value of the Mooney voscosity added from a characteristic torque value is analyzed. That is to say, the relationship of a Mooney-viscosity change value DELTAMG in elapsed times DELTAtGX, DELTAtG until the time tG when the maximum Mooney viscosity appears next since the time tmin when the maximum Mooney viscosity first appeared, is found. Especially, regarding the same mixture of right rubber which contains a filler much, Mooney-viscosity curves of three kinds of unvalcanized rubber at G>H>J are compared with from the rubber in which a dispersion state is better. Then, it is clarified that, the larger values DELTAMG, DELTAtG of the unvulcanized rubber are as in the curve J, the worse the dispersion state is. Consequently, the values DELTAMG, DELTAtG are effective as the surface measure of the filler, and they can be used for quality control or the like.
