Title: Shadow mask, method of manufacturing the shadow mask, and display
Inventor: SUZUKI KATSUMI
IPC: H01L51/50
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To manufacture a shadow mask of high accuracy with high numerical aperture. SOLUTION: A shadow mask forming region 12 with a thickness of dozens of micrometers is formed at the center part of a (110) Si single crystal substrate 21 so as to leave an Si frame 11 at the periphery. A thermally oxidized SiO2 film 22 is formed on the front and rear of the (110) Si single crystal substrate 21 using a thermal oxidation method. A resist pattern is then formed on the surface side (the upper face in Fig. 2(b)) of the thermally oxidized SiO2 film 22 using the usual photolithographic technique, and dry etching is carried out using the resist pattern as a protective film to form a SiO2 pattern 22a. A through hole 23 is formed by etching Si using the SiO2 pattern 22a as the protective film. The thermally oxidized SiO2 film 22 which becomes unnecessary is etched and removed using fluoric acid to obtain the shadow mask 24.

Title: Image recorder
Inventor: YAGI KEIICHI
IPC: B41J2/01
Filed: 2001-05-09
Abstract: PROBLEM TO BE SOLVED: To provide an image recorder for recording high quality images speedily. SOLUTION: An ink jet printer 10 has an infrared sensor 26 set to the side face of a carriage 12. The density on a platen is detected by the infrared sensor 26 when the carriage 12 is scanned together with a recording head 14 during printing. Based on the density detected a mask for allowing a control unit 50 to pass/not to pass a printing signal is formed. Hence, even when a paper deviates in a horizontal scanning direction, the platen is prevented from being contaminated because ink drops are prevented from being discharged onto the platen.  Since the infrared sensor 26 is set to the upstream side in a transfer direction with respect to a printing region of the recording head 14, a width of the paper can be detected before printing by simply transferring the paper to the downstream side in the transfer direction (without being transferred in the opposite direction), thus enabling speedy imaging.
