Title: Device to fix both ends of leader tape to reel
Inventor: KUBO YOSHIHARU
IPC: G11B23/20
Filed: 1982-06-16
Abstract: PURPOSE:To miniaturize a disk, by providing a meandering pin on a disk containing an array of plural pairs of reels where two reels make a pair on its circumference to give a zigzag movement to a leader tape, and turning a disk after cutting and fixing the leader tape to the reel. CONSTITUTION:Plural pairs of reels are attached at the circumference of a disk 3 which turns round a shaft 4, and a leader tape 2 is drawn out to the fixing position. The tape 2 is hooked to a hook pin 21 by means a meandering means 18 to give zigzag movement to the tape 2. A tentative hooking open member 9 approaches to adsorb the tape 2, and the tape 2 is cut by a cutter 6. The both ends of the cut tape 2 are fixed to the groove of a hub by means of a pressure member 8 and a clamper. When this fixing is over, the disk 3 turns by 60 deg. in the case of an example shown in the figure. Then the next pair of reels 1 comes to a position opposite to the cutter 6, and the tape 2 is cut in the same way. A set of reels 1' and 1'' at both ends of the cut tape 2 is removed, and a new pair of reels 1 is attached. This can increase the length of the tape 2 by using a miniature disk.

Title: Production of forged steel product
Inventor: TODA SHIGEYUKI
IPC: B21J5/00
Filed: 1981-07-07
Abstract: PURPOSE:To produce superior forged steel products with conserved energy by heating steel to temps. just above its Ac3 point then subjecting this steel to cooling to the temp. in the gamma recrystallization region and forging followed by cooling to the temp. in the non-recrystallization region and forging further cooling to temps. in the two phase region and forging then cooling. CONSTITUTION:The initial gamma grains obtained by heating steel to temps. just above its Ac3 point and sizing the grains thereof are cooled to the temp. in the gamma recrystallization region and are forged, whereby the grains are fined. These are cooled to the temp. in the non-recrystallization region and are forged to introduce deformation zones in the respective crystal grains so that ferrite (alpha) is dispersed and deposited with the deformation zones as nuclei. The grains are cooled to the temp. in the two phase region and are forged to apply working to the dispersed and deposited fine grains alpha so that the grain fining is more accelerated by the recrystallization of the alpha, or the formation of subgrains, the restoration of the low structure, etc. Finally, these are air cooled or cooled with spray water, after which they are allowed to cool by air, whereby the remaining relatively large gamma grains are transformed to fine pearlite, bainite or martensite.

With such a structure, the pattern on the surface protective film applied with an external force to the surface of the element is deformed and the regularity of the pattern on the portion is disordered. Accordingly, the discovery of the malfunction due to the observing inspection can be ready.

Filed: 1978-08-28
Abstract: PURPOSE: To remove damaged layer caused by etching by altering etching parameter after etching with large etching rate condition or thermally treating it.  
     CONSTITUTION: When etching with low power after etching with high power under large etching rate condition, it can etch with less damaged layer for short time. Since the etching gas pressure relates to the production of damaged layer, the etching is conducted under high pressure after etching under predetermined gas pressure of predetermined gas, it can essentially remove the damaged layer chemically. It is also effective to thermally treat it after etching to arrange the disorder of atomic array in the vicinity of the surface. These etching step is continuously or stepwisely executed under different conditions, and thermally treated at higher than 530°C. to cause effective result.
