Title: Picture recorder
Inventor: SEKIZAWA HIDEKAZU
IPC: H04N1/41
Filed: 1993-09-24
Abstract: PURPOSE:To realize the reduction of a picture memory and efficient transmission even at the time of printing a multilevel color of high picture quality by storing picture data in the compressed state and expanding it in accordance with the printing speed. CONSTITUTION:An RGB or Lab signal is inputted from an input part 101. In the case of RGB, it is first subjected to color conversion to Lab of CIE and is next subjected to picture compression by a color conversion and picture compressing part 102. Compressed picture data is recorded in picture memories, namely, a luminance memory 103, a color difference 1 memory 104, and a color difference 2 memory 105. Stored picture data is subjected to expansion processing and color conversion by parts 106 to 109 which reproduce respective printing color signals. Reproduced color signals Y, M, C, and K are successively recorded on recording paper by recording parts 111 to 114 of the four continuous drum recording type. A sensor is arranged which detects that recording paper passes from each of recording parts 111 to 114, and expansion and conversion parts 106 and 109 are operated based on passage of the paper by the control signal of a recording control part 110.

Title: Inspecting method for lsi
Inventor: HAMADA HIROYUKI
IPC: H01L21/66
Filed: 1993-09-24
Abstract: PURPOSE:To visualize a wiring potential in an image with a good contrast by a method wherein electron beams are continuously cast on an LSI chip to alternately change a potential to a low potential and a high potential like pulses, a time when the low potential is held is made longer than a time when the high potential is held, and a secondary electron detected in a state of the high potential after the low potential is formed in an image. CONSTITUTION:A potential of a wiring of an LSI covered with a passivation film as an insulating film is changed alternately to a low and a high potentials like pulses and, electron beams are continuously cast on the LSI. A time when the wiring potential is low, is kept long, thereby making a potential on the insulating film close to V0. Moreover, a time when the wiring potential is high, is made short not to let the potential on the insulating film approach V0. When the cycle is continued, the potential on the insulating film when the wiring potential is low, becomes close to V0, and a difference of the potential on the insulating film when the wiring potential is high, from V0 is close to an amplitude of the wiring potential. Therefore, the state of the high potential can be formed into an image with a good contrast if photographed at this occasion. Accordingly, a troubled point of the LSI is easily discovered.
