Title: Photosensitive composition, pattern forming method using the same, and formation of fluorescent screen
Inventor: MORISHITA HAJIME
IPC: H01L21/027
Filed: 1991-10-23
Abstract: PURPOSE:To obtain high sensitivity and to improve dispersibility in an aq. soln. by preparing a compsn. from specified copolymers and derivs. of polyvinyl alcohol having double bonds in side chains which react with these copolymers when the copolymers are photodissociated. CONSTITUTION:This photosensitive compsn. consists of copolymers and derivs. of polyvinyl alcohol having double bonds in side chains which react with these copolymers when these copolymers are photodissociated. These copolymers have at least water-insoluble insensitive monomer units and monomer units having azide groups and electrolytic functional groups. These copolymers have higher mol.wt. compared with alkali bichromate conventionally used as a photocrosslinking agent and have more photocrosslinking groups in one molecule. Since the photocrosslinking agent of this invention has high mol.wt., entanglement with acetals of polyvinyl alcohol as the base polymer is caused to improve the crosslinking efficiency of the photolyzed photocrosslinking agent to the polyvinyl alcohol. Moreover, by using acetals of polyvinyl alcohol, the compsn. is efficiently made insoluble.

Title: Paper feeder for printer
Inventor: IWAI HIROJI
IPC: B41J19/94
Filed: 1984-12-25
Abstract: PURPOSE:To contrive a reduction in size and simplification of construction of a printer, by feeding a paper by utilizing a motor for driving a rotary wheel. CONSTITUTION:When an end of an interlocking member 7 is depressed downward by an operating piece 4A, a ratchet pawl 6 movably fitted to the other end of the member 7 is moved upward to feed a ratchet wheel 5 forward by one tooth, whereby a platen 3 is rotated, and the paper is fed by an amount corresponding to the forward rotation of the wheel 5. Therefore, when the operating piece 4A is rotated plural times and the member 7 is moved up and down plural times, the ratchet wheel 5 is rotated forward by a corresponding amount to thereby feed the paper. Accordingly, since the paper is fed by utilizing the motor for driving the rotary wheel, the need for a driving motor used exclusively for feeding the paper can be eliminated, and the paper feeder can be reduced in size and simplified in construction.

Title: Emergency shutoff device for liquid storage tank
Inventor: MITSUISHI MASAHIRO
IPC: F16K17/34
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To keep a fixed quantity of liquid, such as drinking water, in a liquid storage tank even if a supply pipe and the like connected with the liquid storage tank are damaged by an earthquake. SOLUTION: In case where a supply pipe 3 and the like connected with a liquid storage tank 2 are damaged due to occurrence of an earthquake, and a liquid, such as drinking water, stored in the liquid storage tank 2 flows out from its damaged part, the level of the liquid drops as the liquid flows out, and following this a valve 4 with a float 4, which is floating on the liquid in a higher position facing the outlet port 2a of the liquid storage tank 2, also moves down. The valve 42 of the valve 4 with the float finally sits on the opening of the base end of the supply pipe 3 to close the outlet port of the liquid storage tank 2. As a result, the pressure of the liquid in the liquid storage tank 2 acts on the valve 42 closing the outlet port 2a, and it firmly presses this valve 42 into the closing position. That is, even if the supply pipe 3 and the like connected with the liquid storage tank 2 are damaged, the outflow of the liquid in the liquid storage tank 2 is securely prevented after that, as long as the liquid tank 2 is not damaged. Therefore, the fixed quantity of liquid is kept in the liquid storage tank 2.
