Title: Method for introducing rod-like part into hole
Inventor: AOYAMA YOSHITAKA
IPC: B23P19/02
Filed: 1988-04-16
Abstract: PURPOSE:To introduce a rod-like part into a hole correctly by putting the rod- like part to face a guide pin inserted in a hole at a correct position by means of a transfer rod, magnetizing the guide pin to suck the rod-like part, and then making it retreat. CONSTITUTION:A guide pin 2 is inserted into a fixed electrode 1 and a hole 7 in a steel plate part 6 by a pushing force of a spring 8. A rod-like part 9 is held by a transfer rod 11 at its flange part 10 to be positioned at a correct position (just over the pin 2). In this condition, a magnetic force is applied to the guide pin 2 by upward motion of a magnet 16, so the rod-like part 9 is sucked by the guide pin 2. The guide pin 2 is moved down as it is sucked, so the rod-like part 9 is inserted into the hole 7 smoothly, and the steel plate 6 and the flange 10 are welded to be fixed to each other. Because the rod-like part 9 is transferred to the correct position and then sucked, it is introduced into the hole correctly.

IPC: F16B39/00
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To prevent worsening of flatness of a flange surface when a serration for a bolt is press-fitted in a flange. SOLUTION: This tightening structure is such that a bolt 5 in which a serration 7 is formed in a part in an axial direction of an outer peripheral surface 6 is press-fitted into a bolt hole 3 formed in the flange part 2 of a mounting member 1. The serration 7 is spaced away from the two end faces 2A and 2B of the flange part 2 by first and second distances D and C, and the first and second distances D and C exceed 13% of the thickness A of the flange part 2. Thus, the serration 7 presses a bolt hole inner peripheral surface 13 only in the region, spaced far away from the two end faces 2A and 2B, of the flange part 2.

Title: Recognition system for transmitting multiple address signal
Inventor: IWANO TATSUYA
IPC: H04L12/42
Filed: 1989-04-13
Abstract: PURPOSE:To prevent the induction of the congestion of a transmitting source processor by sequentially recognizing the transmission of a multiple address signal between adjacent processors. CONSTITUTION:When congestion occurs in a slave processors 30 and a reception buffer for multiple address 104 does not become vacant, a negative response informing the effect that the multiple address signal cannot be taken is transmitted with respect to the reception of the multiple address signal from a response frame transmission circuit 106. In the master processor 20 of the adjacent processor which has received the negative response, a reset signal is not outputted from an address control filed detection circuit 102 to a multiple address transmission flag flip flop 113. Thus, a supervisory timer 115 is timed out and the multiple address signal remained in the reception buffer for multiple address 104 is retransmitted. Thus, it is prevented that the response is concentrated on the transmitting source processor and that it comes to the congested state.
