Patent JP-H0289531-A (JP)
Title: Spin-forming method
Inventor: OCHIAI KIMIO
IPC: B21H1/04
Filed: 1988-09-21
Abstract: PURPOSE:To facilitate the maintenance of the strength of a formed product by forming a narrow part at a joint part between a stock cylinder and a plate part to be held when the stock cylinder to be formed provided on the peripheral edge of a plate part to be held is put round a forming mandrel. CONSTITUTION:For example, a rear rim stock cylinder 3 is forged or cast integrally with the rear peripheral edge of a disk part D (a plate part to be held) of the wheel stock 1 for a vehicle. A narrow part 312 is formed on the outer wall surface in the joint part between the stock cylinder 3 and the disk part D. The narrow part 312 extends in the shape of a groove over the peripheral surface of the stock cylinder 3. This stock 1 is installed on the mandrel 4, the mandrel 4 is rotated round the axis 43, the stock cylinder 3 is ironed by a rotary pressure tool 5 in the direction of an arrow and a rear rim 31, further, the wheel W are formed. In this case, since the narrow plate is formed, corrosion hardly occurs, as a result, the strength of a spin-formed product is easily kept.

Title: Soldering method of printed board and jet-flow solder bath
Inventor: ZEN MITSUO
IPC: B23K1/08
Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To attach a large amount of solder onto a television circuit and attach a small amount of solder to a video circuit by carrying out soldering in changing a flowing state of molten solder, while a printed board comes into contact with the molten solder. SOLUTION: As for a flow state of the molten solder in a jet flow solder bath 1, when a tip of a leaving side former 7 rises a little, flow rate of the molten solder flowing on the leaving side former 7 is low and a small amount of solder attaches to a printed board, and a video circuit of the first half of a printed board is soldered. When it is positioned at a peel back point, a motor 11 rotates a crank 10 and a tip of the going-out side former 7 lowers a little, thus making flow rate fast. A television circuit of the latter half of a printed board breaks away at the rapidly flowing part, and a large amount of solder is attached if a printed board is soldered.

Title: Method and device of feeding coolant during grinding work
Inventor: MARUYAMA TAKASHI
IPC: B24B55/02
Filed: 1987-09-24
Abstract: PURPOSE:To reliably feed an enough coolant to a space between a workpiece and a polishing cloth paper, to prevent the occurrence of choking with a polishing cloth paper, and to improve machining precision, by a method wherein a coolant is caused to enter from the non-contact part of the polishing cloth paper to a space between the workpiece and the contact part of the polishing cloth paper. CONSTITUTION:A work 10 is rotated in a state to press a part, in which a through-hole 68 of a polishing paper 20 is formed, against a work 10 to perform a grinding work. In this case, a coolant fed through a hose 84 fed through the through-hole (non-contact part) 68 of the polishing paper 20 to a space between the work 10 and the contact part of the polishing cloth 20. In this case, since coolant feed passages 72 and 74 are opened to projected parts 62 and 64 pressing the surroundings of the through-hole 68 against the work 10, the coolant is forced to enter between the work 10 and the polishing paper 20. The entering coolant is spread over the whole of a contact part between the polishing paper 20 and the work 10 along with rotation of the work 10 to wash out grinding powder. As a result, the occurrence of a hocking of the polishing paper 20 is reduced, and machining precision is improved.

Title: Method for supplying thread to sewing machine and latch for thread supply
Inventor: MURAGAKI RIYOUICHI
IPC: D05B53/00
Filed: 1989-09-14
Abstract: PURPOSE:To eliminate a twist while enabling, if any, the twist to be eliminated until it reaches a sewing machine by supplying a thread from a bobbin winder to the sewing machine while holding the twist or a loop produced by the twist on a latch. CONSTITUTION:A thread 19 is supplied from a bobbin winder 10 to a sewing machine 11 through a hook 18 provided above the bobbin winder 10 so that a twist loop 2 is hooked on the hook 18. The twist loop 2 thus formed is held by the hook 18, so that the thread 19 from the bobbin winder 10 is supplied while rubbing on itself in a twining part 1 formed on the lower portion of the twist loop 2. Thus, even if the twist loop 20 is produced by any twist on the thread 19 immediately after it is withdrawn from the bobbin winder 10, said loop is eliminated by passing through the twining part 1, since the twist loop 20 is gradually undone by the thread rubbing on itself when the twist loop 20 is lifted to reach the twining part 1.
