Title: Manufacture of mask for short wave length lithography
Inventor: KOBAYASHI SHUNICHI
IPC: G03F1/80
Filed: 1986-04-17
Abstract: PURPOSE:To simplify a process face while thinning the thickness of an silicon nitride film at a position where X-rays are transmitted, and to prevent the deterioration of a contrast by growing the silicon nitride film only by one process. CONSTITUTION:A predetermined mask pattern 11 is formed on the surface of an silicon base 10 constituting a susceptor by a heavy metal, such as gold, tantalum, etc. Silicon nitride films 12, 13 in thickness of approximately 1mum are grown on both the surface and back of the silicon base 10 through a CVD method, etc. including the mask pattern 11. The silicon nitride film 13 at a position opposite to said mask pattern 11 in the back of the silicon base 10 in which there is no said mask pattern 11 is removed selectively through etching to bore a window 14. The base 10 exposed from the window 14 is removed through etching, using the silicon nitride film 12 left on the back of the silicon base 10 as a mask, thus forming a cross section to a bridge shape. The etching process is executed until the base silicon 10 is removed completely and the mask pattern 11 under a buried state in the silicon nitride film 12 on the surface of said base 10 is exposed from the back.

Title: Image recording device
Inventor: SAITOU SUSUMU
IPC: H04N1/23
Filed: 1983-05-19
Abstract: PURPOSE:To improve the resolution of an image and a recording speed by constituting a means which drive control electrodes for controlling the scattering of toner according image information in such a way that plural control electrodes corresponding to interlaced picture elements are driven at the same time. CONSTITUTION:When image information on one scanning line is set in each driving circuit 11, a timing circuit 12 supplies a driving timing signal to odd- numbered driving circuits 11 through a signal line 13a. Corresponding control electrodes 5 of the driving circuits 11 supplied with the signal are driven to record corresponding picture elements. Then, the timing circuit 12 supplies the driving timing signal to even-numbered driving circuits 11 through the other signal line 13b at a time. pairs of corresponding control electrodes 5 of driving circuits 11 supplied with the signal are driven to record corresponding picture elements, thus completing the recording of one scanning line. Thus, interlaced control electrodes are driven at different timing simultaneously, so the resolution and recording speed are improved.

Title: Master plate for electrophotographic planographic printing plate
Inventor: KATO EIICHI
IPC: G03G5/05
Filed: 1988-04-13
Abstract: PURPOSE:To enable the uniform and good desensitization of a nonimage part even if an etching processing speed is increased by granulating a resin having a functional group which forms a carboxyl group by decomposition and using the formed particles separately from a binder resin for photoconductive zinc oxide. CONSTITUTION:The resin particles contg. at least one kind of the polymer component contg. at least one kind of the functional group forming at least one carboxyl group by decomposition are incorporated into a photoconductive layer. The resin particles are dispersed in the state of particles into the photoconductive layer separately from the binder resin of the photoconductive zinc oxide. Since the resin having the functional group is dispersed in the state of the particles, the specific surface area increases and the contact of a desensitizing liquid and the binder and eventually the reaction thereof are not hindered. The desensitization of the nonimage part is thereby sufficiently executed even if the etching treatment speed is increased.
