Abstract: <P>PROBLEM TO BE SOLVED: To provide a wiring board and a method of manufacturing the same which is capable of preventing corrosion of vias.  <P>SOLUTION: The wiring board 100 is a multilayer wiring board which consists of multilayer sections 1 and 2, and a core section 3. The multilayer section 1 is formed with vias 71, having a bottom with the core section 3 being the bottom, while the multilayer section 2 is formed with vias 72, having a bottom with the core section 3 being a bottom. The wiring board 100 is formed with a through-via 6. Each conductor layer is properly patterned. In the wiring board 100, a plating layer on the wall faces of the vias 71 and 72 having a bottom is formed by Au which is an anti-corrosive metal. Therefore, even if a liquid sticks to the inside of the vias from cleaning or the like, the plating layer will hardly corrode.  <P>COPYRIGHT: (C)2003,JPO

IPC: G03G21/18
Filed: 2002-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cartridge and an image forming apparatus by which a recorded image quality is prevented from being deteriorated accompanying using of non genuine toner.  <P>SOLUTION: When a detection signal showing the presence of toner is inputted from a photoelectric sensor 65, an MPU 11 on the side of a composite machine 1 sends a flag release asking signal for asking whether the toner lacking flag of a RAM 113 is released or not to an MPU 111. When a response signal showing that the toner lacking flag is not released is inputted from the MPU 111, the MPU 11 sends a control signal for inhibiting the recording operation of a recording part 15 to the MPU 111. As a result, the MPU 111 stops the recording operation of the recording part 15. Consequently, the recording image quality is prevented from being deteriorated accompanying using of the non genuine toner.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-02-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a coating processing device and a substrate treatment device using the same, capable of processing coating of substrates precisely and of processing substrate jointly with external devices efficiently.  <P>SOLUTION: An application dedicated unit 16 applies a coating to the top surface of a substrate W and a cleaning dedicated unit 17 cleans the rear surface of the substrate W and removes the stain of the applied liquid (photoresist liquid) from the same in a cleaning process (back cleaning process). Since the spinning chuck for the cleaning dedicated unit 17 is smaller is diameter than that for the application dedicated unit 16, stain removing capability is enhanced because the area sucked and held by the cleaning dedicated unit 17 is smaller than that sucked and held by the application dedicated unit 16. As the result, liquid application to the substrate W is performed with enhanced precision.  <P>COPYRIGHT: (C)2003,JPO
