Title: Image forming device
Inventor: HAYASHI KOJI
IPC: G03G15/06
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To provide a high-quality image by correcting edge enhancement or edge breaks caused by development bias fluctuation in a small scale circuit by changing the image processing parameters of an image signal processing means corresponding to the feature amount of a development bias. SOLUTION: The image processing parameter of a scanner/IPU part is changed, corresponding to the feature amount of the development bias. Therefore, in the scanner/IPU part, an MTF filter 405 functions especially as a parameter changing means. Then, processing for changing a spatial filter coefficient to the side of edge enhancement can be executed, by changing a filter coefficient in order from filter 1 to filter 4, when matrix-shaped spatial filters 1 to 4 are prepared in the MTF filter 405. Thus, the change in the image quality caused by the change of development bias can be suppressed and image can be formed with optimum conditions at all times.

Title: Method and device for exfoliating thin segment
Inventor: FUJIMURA ISAO
IPC: H01L21/304
Filed: 1988-06-21
Abstract: PURPOSE:To exfoliate a semiconductor wafer from an abrasive board and hold it with catches by inserting two or more catches being distance-adjustable from both surfaces of a semiconductor wafer, between the semiconductor wafer and the abrasive board. CONSTITUTION:A catch 10 is moved backward so that the distance between catches 10 and 11 may become larger than a semiconductor wafer 21 by rotating the knob 5. After that, the catches 10 and 11 are applied to an abrasive board 22. Then, the distance between catches 10, 11 is narrowed by rotating the knob 5 reversely, and the periphery of the wafer 21 is grasped. As the distance between the catches 10, 11 is made narrower, exfoliation occurs inside wax 13 at the peripheral part of the wafer 21 grasped with the catches, in a state that the wax 13 softened with the inclined planes of the catches 10, 11 attaches to the wafer 21. This makes the wafer 21 exfoliate from the abrasive board 22 and the wafer 21 is held with the catches 10, 11.

Filed: 1987-06-19
Abstract: PURPOSE:To compress the scale of a circuit, by providing a preset fixed signal generating means, a select means which replaces a reception fixed signal by a preset fixed signal, and a cyclic redundancy check operation/decision means. CONSTITUTION:The titled circuit is constituted of the preset fixed signal generating means 10 which generates the preset fixed signal, the select means which replaces the reception fixed signal by the preset fixed signal at the means 10, and a decision means 12 which performs the cyclic redundancy check (CRC) arithmetic operation of a signal constituted of the preset fixed signal outputted from the means 11 and a reception varing signal and decides the presence/ absence of a reception signal. When the preset fixed signal is different from the reception fixed signal, it is possible to decide the invalidity of the reception signal by performing the CRC arithmetic operation by the CRC arithmetic operation decision means 12. Therefore, since it is enough to provide only a decision part for a CRC arithmetic operation part as circuit constitution, thereby, the scale of the circuit can be compressed.
