Title: Image forming apparatus
Inventor: GOTO MASAHIRO
IPC: G03G15/16
Filed: 2001-04-06
Abstract: PROBLEM TO BE SOLVED: To optimally transfer an image regardless of the resistance value of recording material and an image pattern. SOLUTION: Transfer bias is corrected from VT0 to VT1 in accordance with a current (resistance value of recording material) flowing to a high-voltage power source circuit when the leading margin part of the recording material is positioned at a transfer nip part between a photoreceptor drum and a transfer roller. Generally speaking, time when the leading margin part is positioned at the transfer nip part is short (T3 to T4) and the resistance value of the recording material is not accurately detected, so that the transfer bias can not be appropriately corrected. Then, a transfer current is monitored further after the correction, whereby the transfer bias is corrected in accordance with the toner amount of the recording material. Thus, optimum constant-voltage control is performed thereafter.  The toner amount of the recording material is obtained based on the exposure time of a laser beam scanner and a developing current during developing.

Title: Check valve
Inventor: WATANABE SEIICHI
IPC: F16K15/02
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To reduce the backflow of a cooling medium without increasing the number of parts. SOLUTION: When a caulking tool 60 is moved down, a tapered face 61 first contacts the outer periphery face of a cylindrical end portion 18 to thrust the cylindrical end portion 18 to the center side in the radial direction. This thrust causes the plastic deformation of the cylindrical end portion 18 to be pulled to the center side and then permits the upper face of the cylindrical end portion 18 in flat press contact with a bottom face 64 to be caulked and a stopper 5 to be fixed to a body. Although an O-ring is arranged in a valve 2, there is no C-ring for fixing the stopper 5 with caulking operation, resulting in no increase in the number of parts.

Title: General-purpose driver server
Inventor: KANEVSKY DIMITRI
IPC: G06F17/30
Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a substitute driver located at a designated server over the Internet. SOLUTION: When a substitute driver having compatibility over the Internet converts a floppy disk incompatible with a computer, a special general purpose bit reader has to be prepared in a server. Instead of this, a bit reader can be arranged in a user computer and connected to a global server. In this case, all files can be accessed via the Internet. Thus, data can be read and written to/from a disk formatted by a different operating system. In order to carry out an application incompatible with an operating system on a computer, where the disk is inserted, a database server which stores the database for applications of different kinds of operating systems retrieves a similar application with a general-purpose driver on the server.
