Title: Laser welding method
Inventor: SAKA YOSHIFUMI
IPC: B23K26/21
Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To improve workability by preheating a laser beam irradiation part of an object to be welded, then welding through a laser beam irradiation, and thereby unnecessitating separate working such as providing projecting parts. SOLUTION: A welding body 17' is abutted on with a body 17a' to be welded. These 17', 17a' are for example copper plates with a low laser absorptivity (less than 10%). The laser beam irradiation part 17e of the body 17a' to be welded is preheated by an arc P to a temperature (e.g. 500 deg.) that is slightly lower than the melting temperature (e.g. 540 deg.) by the irradiation of a laser beam LB. Thus, the irradiation part 17e is sufficiently preheated first, and then the body 17a' is welded to the welding body 17'. The preheating is also desirably done by electrical resistance, continuous oscillation laser or a preheating furnace other than by the arc.; it is also advisable that a material with a high laser absorptivity is attached to the laser beam irradiation part. As a result, it greatly reduces scattering of copper materials due to spattering for example.

Title: Multiblade fan
Inventor: YOSHIHASHI ATSUSHI
IPC: F04D29/44
Filed: 1990-06-07
Abstract: PURPOSE:To improve blasting performance of a fan without changing its noise by providing a suction casing which can give a velocity component to the fluid in the direction opposite to the rotational direction of a multiblade impeller which gives mechanical energy to the fluid. CONSTITUTION:A multiblade impeller 1 produces an air blasting state in cooperation with a blow-off spiral casing 2 and a motor 3. In this case, a suction spiral casing 4 having a form similar to that of the blow-off spiral casing 2 is attached to a suction side of the multiblade impeller 1. This suction spiral casing 4 has such a spiral form that a spiral air flow is produced in the direction opposite to the rotational direction of the multiblade impeller 1. When the multiblade impeller 1 rotates, air is sucked from a suction port 5, and then flows into the multiblade impeller 1 with a velocity component opposite to the rotational direction of the impeller 1 through the suction spiral casing 4. Accordingly, the theoretical head of the fan becomes higher than that in an ordinary suction type or a forward direction spiral suction type fan. So, its blasting performance is improved.

Title: Conveyor device
Inventor: HAYASHI SHIGEKI
IPC: G03G15/00
Filed: 1990-06-07
Abstract: PURPOSE:To suppress the generation of smearing and blurring of an image caused by the scattering and movement of a toner by changing the suction force to recording paper according to the position of the recording paper on a carrier base, and weakening the suction force on the fixing side compared to the transfer side. CONSTITUTION:Each suction port 31 of triangular shape is formed in such a way that the width (the vertical direction to the conveying direction) of each suction port 31 is narrowed from the transfer side toward the fixing side. Accordingly, when recording paper 11 with an image forming toner transferred thereon at a transfer device 21a reaches a carrier base 2, the recording paper 11 is sucked by the comparatively strong and appropriate suction force, but the suction force to the recording paper 11 is weakened as the recording paper 11 approaches the fixing side from the transfer side because of the proportion of the suction port area occupying the carrier base face being decrease. As a result, when the rear end of the recording paper 11 is separated from a conveyor belt 5, the leap of the rear end part is not generated and therefore shock given to the recording paper 11 is lessened, and this results in suppressing the generation of smearing and blurring of the image caused by the scattering and movement of the still-unfixed toner on the recording paper 11.
