Filed: 1986-10-22
Abstract: PURPOSE:To form a highly accurate print pattern quickly with high yield, by employing a squeegee for running ink onto a material to be printed separately from a squeegee for blotting operation. CONSTITUTION:In the stage for running onto a print circuit board 10, a first squeegee 13 slides with a plate 12, and since the underface of the plate 12 is in contact with the print circuit board 10, a portion of ink 14 permeats through the plate 12 so as to form a print pattern onto the print circuit board 10.

Title: Data processor
Inventor: OKAMOTO KAZUAKI
IPC: G06F15/16
Filed: 1991-09-30
Abstract: PURPOSE:To improve the arithmetic efficiency by classifying packets inputted from a packet transfer line into packed for one-input instruction and packets for two-input instruction and preferentially processing packets for one-input instruction than packets for two-input instruction. CONSTITUTION:Packets taken in through an input/output controller 14 are divided into packets for one-input instruction and packets for two-input instruction by a branching circuit 16, and they are respectively fetched into input buffer devices 18 and 20. Packets for two-input instruction are sent to a queuing circuit 22 and are sent to a multiplexer 24 after pairing with the other party of queuing. Meanwhile, packets for one-input instruction do not pass a queuing circuit 20 from the buffer device 18 but is directly sent to the multiplexer 24 through a by-pass transfer line 26. Thus, the arithmetic efficiency is improved because packets for one-input instruction are not affected by the busy state of the queuing circuit 22.

Title: Shearing device for bar stock
Inventor: OKA TOSHIHIRO
IPC: B23D23/00
Filed: 1992-08-28
Abstract: PURPOSE:To obtain each sectional face which is highly accurate and small in level difference by combing a reverse presser and a semicircular blade into a pseudo circular blade only at the time of shearing. CONSTITUTION:A pseudo circular blade is formed by additionally applying reverse pressing force with the semicircular blade 5 of a movable cutting tool 4 combined with the bar stock support face 60 of a reverse presser 6. The pseudo circular blade holds a gap Dc over the diameter D0 of a bar stock W in the shearing direction to prevent its material from being deformed due to the rotation of the bar stock W without restraining the axial movement of the bar stock W during shearing operations. This constitution thereby allows the squareness of a sectional face to be excellent, can prevent the occurrence of tongues, hold-up cracks, collapses in the sectional face, and also can make each level difference small, even when a clearance between a fixed cutting tool 1 and the movable cutting tool 4 is small.

Force due to magnetization becomes stronger suddenly just before the maximum contraction of said spring 1 and with continuous change in its strength up to then. Namely, the extending force of said spring 1 increases suddenly just before the maximum contraction of the spring 1 and noninterruptedly up to then. Thus the spring different in its characteristics from an ordinary one can be produced.
