Title: Wheel conveyor
Inventor: FUTAKI AKIRA
IPC: B65G13/11
Filed: 1986-12-18
Abstract: PURPOSE:To simplify assembling, by bending the opposite end sections of the upper face of a frame into U-shape then forming a wheel shaft fitting groove in the inside face and a shaft end section engaging means on the outside face thereby receiving a wheel shaft. CONSTITUTION:A wheel 3 is fixed to a wheel shaft 4 which is inserted into a supporting groove 5 in a frame 1. Here, the end section of the shaft 4 is fitted while riding across a projection 6 of the frame 1 under resilient state. Consequently, the shaft 4 is supported rotatably in the supporting groove 5 with upward motion thereof being blocked. With such arrangement, a wheel conveyor can be assembled as a sub-assembly where the wheel is fixed previously to the supporting shaft. As a result, number of parts can be reduced and assembling is simplified.

IPC: B23Q15/00
Filed: 1991-10-24
Abstract: PURPOSE:To prevent cutting-in caused by an end mill, and also, to prevent a command operation of the end mill from drawing a turning-back locus by constituting the end mill so that a grid point in a flat end mill tool radius on a flat part from a grid point of a connecting part of the flat part and a slant part is not outputted as cutting data except the connecting part.

In this regard, each point in a specific check path (i) and its normal vector are shown. In such a state, for instance, when a tool radius (D/2) is set to 2-3 folds of an interval between a point and a point, a point which is not outputted as NC data generating data, that is, a point to be thinned out becomes points 12, 13 in the case of (A), there is no point in the case of (B) and (C), and it becomes points 45, 46 in the case of (D). Other points than these points are all outputted. In such a way, a tool on a moving path causes no cutting-in on the slant face, nor advancing while tracing a turning-back locus.
