Title: Photosensitive composition
Inventor: KUSUFUJI TAKESHI
IPC: G03F7/00
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To obtain a water-soluble or water-dispersible photosensitive compsn. which does not cause dropping of PVA in a hardened part during development with water, by constituting the compsn. of a vinylalcohol-based polymer having specified double bonds, unsatd. monomers having ethylene-type double bonds, and a photopolymn. initiator. SOLUTION: This photosensitive compsn. contains a vinylalcohol polymer having double bonds expressed by the formula, unsatd. monomers having ethylene-type double bonds, and a photopolymn. initiator. In the formula, A is a <=20C hydrocarbon group having ethylene type unsatd. double bonds which may be interrupted by oxygen atoms, nitrogen atoms or sulfur atoms. The upper limit of the carbon number of the hydrocarbon group is <=20, and preferably <=15, and more preferably <=10. The PVA used for this photosensitive compsn. is selected so as to use the reaction of aromatic amino groups and unsatd. monomers having epoxy groups and ethylene-type double bonds. Since the reaction is efficiently carried out in water, the PVA itself can be used as a photosensitive compsn.

Title: Semiconductor integrated circuit
Inventor: SEKIDO SAIKICHI
IPC: G01R31/3185
Filed: 1988-08-12
Abstract: PURPOSE:To reduce the number of signals exclusively for selection of functions by enabling the selection of functions in three or four ways with respect to each of input signals for the selection of functions. CONSTITUTION:When a reset input signal-R is at a low level as indicated by settings (a) and (b), outputs of NAND circuits 5 and 7 attain a high level and a function specifying signal F1 and a function specifying signal F2 become the same in the level as a signal S. For example, when the set input signal-R is at a high level and a function selection input signal S is a pulse input as indicated by a setting (e), flip flops 2 and 3 are both set and both the function specifying signals F1 and F2 attain a high level. In other words, the combination of the signals F1 and F2 differs depending on whether the function selection input signal S is at a high level or a pulse input, thereby enabling the selection of functions is three ways by one selection input signal.
