Title: Developing device
Inventor: SAITO TETSUO
IPC: G03G15/08
Filed: 1991-04-19
Abstract: PURPOSE:To provide a developing device properly detecting a residual toner inside via a change in electrostatic capacity, without having a problem such as the void of an image. CONSTITUTION:In the developing device arranged in parallel with a developer carrier and having a residual toner detecting means 20 detecting the residual toner by the change in the electrostatic capacity with respect to the developer carrier, the width L2 of the main detecting part 20a of the residual toner detecting means 20 is set narrower than the maximum paper passing width L1 of a transfer material in a paper passing possible width. The presence of the residual toner inside the developing device is detected by the main detecting part 20a, so that even if an image is consecutively formed on a small sized transfer material, the main detecting part 20a can surely detect the lack of the toner inside the developing device, on the paper passing part of the transfer material.

Title: Error correction and parallel check for product code
Inventor: ZOOK CHRISTOPHER P
IPC: G06F11/00
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a method of a P/Q decoder for generating a CRC syndrome concurrently with the correction of a product code. SOLUTION: A P/Q encoder/decoder 2 has a buffer 26 for storing read/write data, a controller 28 for arbitrating its access, a primary ECC/syndrome generator 29, a (Reed-Solomon) error corrector 30, and a secondary ECC generator/ correction checker (CRC) 32. When data are completely processed by using the primary ECC, for a multilayer error detection/correction EDAC, the check syndrome generated by the secondary ECC immediately checks the validity of correction, so that an unwanted path is removed when the uncorrectable error is not found after P or Q path end. When a code word having no error is skipped during the repeated paths of multidimensional primary ECC, the check syndrome of the secondary ECC compensates skipped data bytes.

Title: Method and apparatus for automatically determining type of print head installed in laser printer
Inventor: CLARKE CYRUS BRADFORD
IPC: G02B26/10
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To detect the type of laser printer head among more than one type installed in a laser printer by generating an electric output signal every time when a periodic optical energy is received and operating the time interval of continuous reception of the electric output signal. SOLUTION: At the time of determining the type of a print head installed in a laser printer 10 compatible with more than one type of print head, an operating system measures the 'lock' frequency of a print head by detecting the time interval of HSYNC pulse signal, e.g. an HSYNC photosensor signal, being fed back in order to synchronizing the position of a laser relative to that page at a common given frequency of an input reference clock. A time interval to be detected by the system is then determined by dividing the pulse frequency of the HSYNC signal and the type of an installed print head is determined from the time interval thus determined.
