Title: Area bump array package, electronic part and bump formation
Inventor: MISHIMA HIDETAKE
IPC: H01L23/12
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent or reduce bump connection defect in an area bump array package. SOLUTION: A bump 35 used as a terminal in an area bump array package is formed to a column, a cone or a truncated pyramid whose arrangement surface vertical direction size is large when compared to a sphere of almost the same volume. When reflow for forming connection by a bump 35 is finished, a resin board 32 sinks. Since an amount δ2 of the sinking includes sinking due to deformation of the bump 35, it is larger than a sinking amount δ1 produced when a spherical bump is used. Since a sinking amount increases from δ1 to δ2 , large warp of the resin board 32, etc., can be absorbed and connection defect relating to the bump 35 can be eliminated or reduced.

Title: Swirl type intake air port with deflector for engine
Inventor: KIOKA SEIJI
IPC: F02B31/00
Filed: 1993-01-22
Abstract: PURPOSE:To perform the proper generation of an intake air swirl during low speed operation and prevent lowering of charging efficiency. CONSTITUTION:A swirl chamber 3 is linearly communicated with the tip part 2 of the intake air port 1 of an engine E. A ridge part 7 is formed in a vertically running state at a part nipped between an intake air port tip part 2 and a swirl chamber 3 and a deflector 10 is vertically rockably supported to the lower wall 8 of the intake air port 1, the ridge part 7 is sharply pointed, and a lower part 14 is gently rounded. Since, during low speed operation, the deflector 10 is displaced to the pointed upper part 13 of an edge from the ridge part 7, the generation of intake air resistance owing to a swirl is more reduced compared with a conventional type, and lowering of the charging efficiency of an engine is prevented from occurring.

Title: Floor nozzle for vacuum cleaner
Inventor: KATO KIMINORI
IPC: A47L9/02
Filed: 1992-02-14
Abstract: PURPOSE:To obtain a floor nozzle which enables reduction in operating force thereof without cleaning over the direction of rotation of a motor. CONSTITUTION:A drive roller 6 is mounted on a rotating shaft 3 of a motor 6 and an intermediate roller 7 which approaches or separates from the drive roller 6 abutting on a wheel 5 is pivoted on a rotating shaft 8 of the wheel 5 free to oscillate. A contact 10 with a tip part 11 contacting a floor is mounted on an oscillation lever 9. The contact 10 tilts backward with a floor nozzle advancing and the intermediate roller 7 abuts the drive roller 6. The rotation of the drive roller 6 is transmitted to the wheel 5 through the intermediate roller 7 to allow the reducing of an operating force for advancing the floor nozzle. In retraction, the contact 10 tilts forward to make the intermediate roller 7 separate from the drive roller 6. This eliminates forcible operation to retract against a torque of the motor.

Title: Weighing and packaging device
Inventor: OSHIMA YASUSHI
IPC: B65B1/32
Filed: 1987-02-09
Abstract: PURPOSE:To enable high-accuracy combinational weighing operation with small- sized constitution by supplying an article to only a linear feeder where the article is supplied to its weighing tank out of linear feeders. CONSTITUTION:Articles are supplied onto the linear feeders 36a and 36b and chute plates 42a and 42b respectively. When a linear feeder 36a corresponding to an empty weighing tank 12a vibrates in this state to supply an article to the empty weighing tank 12a, the chute plate 42a extending from the linear feeder 36a vibrates together with the linear feeder 36a and supplies the article to the linear feeder 36a. The chute plate 42b extending from the linear feeder 36b which does not vibrate, on the other hand, does not vibrate naturally, so no article is supplied to the linear feeder 36b. Thus, while the selected article is discharged and a new article is supplied and weighed, combinational arithmetic based upon the weighed value of an article which is not selected is performed, so the high-accuracy weighing operation is carried out.
