A process card 12 is housed in a card container 7 through an insertion port 14 which is open sideways by allowing an engagement section 11 to be deformed upward against elasticity. Pull out can be prevented by returning the engagement section 11 to the original state by the force of elasticity. The carrier vessel 1 which is transferred to a receiving base 38 is adapted to correct its positional deviation in automatic mode by a receiving apparatus 40 and supported thereby. Stock is checked for by operating a stock sensor 41. Then, a card sensor 42 operates. If the process card is properly set, no light will enter the card sensor 42, which indicates that the card is properly set. It is, therefore, possible to detect easily whether or not the card is properly set.

Abstract: PURPOSE:To provide a saw with high performance by forming a blade plate into a wavy shape, and making it wind left and right by means of a saw setting machine, and further grinding off a part of the tip outer surface of each blade piece. CONSTITUTION:A great number of blade pieces 3 are made in a grinding manner on a plane blade plate 1, and each blade piece 3 is allowed to-wind left and right by the use of a saw setting machine for projecting the tip part 3a sideways and making it a saw blade 2, and thereafter the blade plate 1 corresponding to the saw blade 2 is subjected to a wavy process. In this fashion, the directions of each blade piece 3 lying in front and in the rear change slightly gradually and thus the width of the blade changes slightly, as a result, spring effects exert on the cutting surface and saw blade, so that the cutting speed can be made high. On the side surface of each blade piece, a longitudinally straight side blade 4a intersecting the tip blade 3b of the blade piece is formed, thereby improving the rectilinear movement during cutting and raising the cutting speed, furthermore, reducing scratches to the cutting surface and therefore rendering the finish of the cut surface excellent, and also improving the radiation of frictional heat in the blade plate.

Title: Forging method of stepped shaft material
Inventor: ONO SHINICHI
IPC: B21J5/06
Filed: 1993-09-06
Abstract: PURPOSE:To provide the forging method not causing large tensile stress in a stepped shaft material. CONSTITUTION:In the forging method of a stepped shaft material, which has a tapered part 1b connecting a large diameter part la and small diameter part 1c, is forged in a range of d/D <=0.6 with taking D for a diameter of the large diameter part 1a and d for the small diameter part 1c, L as taken for a length in the axial direction of the tapered part 1b is set in a range of 0.5D<=L<=0.7D. During tap finish forging of the small diameter part, tensile stress is prevented from being produced near the surface part of the large diameter part 1a adjacent to the tapered part 1b, preventing tensile stress from generating crack defect at this part. As a result, rejection after forging is eliminated, further, the thermal stress at subsequent heat treatment process is not concentrated in this part, preventing crack. Further, the cracking in use as a final product is greatly reduced.
