Title: Method for laser welding resin component and laser welding device
Inventor: SAKAGAMI YUJI
IPC: B23K26/32
Filed: 2003-05-29
Abstract: <P>PROBLEM TO BE SOLVED: To prevent a finished product which meets no required welding strength due to a gap generated in the welded part from being manufactured.  <P>SOLUTION: The joint flange part 4a of a half component 4 which absorbs a laser light 6 and a joint flange part 5a of a half component 5 which allows transmission of the laser light 6, are butted to each other and weld-joined at a joint area 9 by emitting the laser light 6. The laser welding is divided into two processes, i.e. tack welding and regular welding and in the meantime, an airtightness test is conducted. In the tack welding, when a gap G exceeds the tolerance limits G<SB>0</SB>, a compatible layer 14 is not formed and therefore, the judgement of the airtightness test results is "leakage present". Consequently, the half component 5 is rejected as a non-conforming article before applying the regular welding. On the other hand, the gap G falls within the tolerance limits G<SB>0</SB>in the tack welding, it is judged that the compatible layer 14 is formed and "no leakage is present" and therefore, the regular welding is applied for the first time.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To secure the stability of an image when the resolution of a toner image is enhanced.  <P>SOLUTION: An image forming apparatus receiving an instruction to output the changeover of the resolution makes judgement with respect to the resolution by being instructed by a user on an operation and display part or a printer driver, that means, judges whether it is 600 dpi output or 1200 dpi output (S1 and S2). In the case of 600 dpi (yes in S3), the interval of real time gradation correction is set once in every ten sheets (S4, S5 and S6), and in the case of 1200 dpi (no in S3), it is set once in every five sheets (S7, S8 and S9). Thus, the occurrence of instable output due to the changeover of the resolution from 600 dpi to 1200 dpi is evaded.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
