Filed: 1986-11-10
Abstract: PURPOSE:To reduce the producing days of a product by interposing a joint plate with the specific plate thickness difference between preceding and succeeding steel bands and then, welding the joint plate to the respective steel bands. CONSTITUTION:A magnet conveyor 6 is arranged with respect to a joint plate charging device 5 and differential rolls 1 and 7 and a threading guide 3 for the upper pass are arranged respectively. The rear end of the preceding steel band while being passed through the upper pass 14 is stopped at a (y) part in a welding machine and the joint part 4 is supplied onto the conveyor 6. Next, the joint plate 4 is welded to the rear end of the preceding steel band and continuously, the succeeding steel band on standby on the lower pass 15 is superposed on the edge of the joint plate 4 to perform the welding. The differences in the plate thickness among the joint plate 4 and the respective steel bands are set within 0.25mm respectively. Since the continuous joining of the steel bands is stabilized and the effective setting of a plate passing schedule is made possible, the producing days of the steel bands can be reduced by this method.

Title: Fuel injection engine
Inventor: SHIOBARA SHOICHI
IPC: F02D41/04
Filed: 1989-10-18
Abstract: PURPOSE:To highly accurately control a small injection amount without using a high accurate injection valve by changing a valve opening time in accordance with an intake air amount, in the predetermined operational condition, and a number of injection times in a plurality of cycles, in the other operational condition, so as to control the injection amount. CONSTITUTION:In a predetermined operational condition, for instance, at the time of high and intermediate load operations, because of both a large injection amount and a long injection time width, injection valves 40a, 40b are enabled to follow-up open-close timing with injection performed intermittently one time or a plurality of times in the determined timing in 1 cycle of an engine 10. At the time of high speed and high load operation, the improvement of fuel consumption is contrived by reducing the respective injection amount. On the other hand, at the time of load operation with a throttle opening in not more than a fixed value, an injection time, determined by a control unit 62, is decreased. At the time of the low load operation where the throttle opening is decreased to not more than the predetermined value, injection is performed by thinning its number of times without corresponding to 1 cycle of the engine 10 in a range of high speed side from the predetermined speed lower than an idling speed.

Title: Soldering method for work with bump
Inventor: NAGAFUKU HIDEKI
IPC: B23K31/02
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a method for soldering a work with bump on the pad of the work with satisfactory conduction, so that a solder bridge does not occur without using flux. SOLUTION: A work 1 with bump is vacuum-sucked to a head and a bump 2 is pressed to a solder part 12 on a pad 11 of a work 10. Then, a projection part 3 of the bump 2 partially destroys an oxide film 15 and is abutted on the melted solder part 12. Then, it settles down on the pad 11. Then, the melted solder part 12 is cooled and solidified, and the bump 2 is bonded on the pad 11. Since the oxide film 15 covers the surface of the solder part 12 as a hard shell, the solder of the solder part 12 does not flow to a side, even if the bump 2 is pressed against strongly, and a solder bridge does not occur.
