Title: Fixing device
Inventor: YURA JUN
IPC: H05B3/00
Filed: 2001-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a fixing device suitable for a color image forming device whose rising time is short by reducing the heat capacity of a heating member while securing the contact area of the heating member with a fixing belt. SOLUTION: The endless fixing belt 2 is sufficiently heated by the heating member 3 constituted by using a surface heating element on the upstream side of a nip between a pressure roller 5 and the belt 2, and an image is fixed at the nip by the belt 2 heated to specified temperature, then only the belt having the small heat capacity existing on a surface layer is heated so that the rise time is shortened by as long as time obtained because the elastic layer 4b of a fixing roller 4 is not heated. Since the image is fixed at the nip after the belt 2 is sufficiently heated by the member 3, the temperature is instantaneously recovered even when the temperature of the belt 2 is lowered at paper passing time, temperature stability becomes excellent, and the fixing property and the gloss of a fixed image are stabilized.  Since the member 3 is the surface heating element, the heat capacity is reduced and responsiveness is improved. By arranging the member 3 proximately to the roller 4, space saving and the reduction of cost are realized.

Title: Substrate processing apparatus
Inventor: MOTOMURA MASAHIRO
IPC: C23F1/08
Filed: 2001-05-25
Abstract: PROBLEM TO BE SOLVED: To provide a substrate processing apparatus which is able to restrain the transfer of a particle when lifting a substrate from a deionized water. SOLUTION: A carrier robot TR conveys a plurality of substrates W to each processing tank (chemical tanks CB1 and CB2, water washing tanks WB1 and WB2, multi-function tank MB and a low pressure drying part LPD) as lots. The conveying order is decided in advance, and a surface washing processing of a substrate W with SC2 (hydrochloric hydrogen preoxide mixed water solution) is conducted before a surface processing with hydrofluoric acid. By doing so, a chelate-forming metal adhered to the substrate W is dissolved by acid. As a result, a metal ion, and a silicon oxide, which is an etching residue, do not combine together even when a etching processing of a silicon oxide film is conducted by soaking the substrate W into the hydrofluoric acid; the forming of particles can be prevented; and the particle transfer when lifting the substrate W from the deionized water can be restrained.
