摘要:
A novel photosensitive resin composition, which has fairly high sensitivity to light and developable with water comprising of essential components a resin represented by the general formula (I), ##STR1## wherein X, which may be present or absent, represents acetic acid when present, Y stands for a group containing carbon-carbon double bond(s) represented by the formula (II), ##STR2## n is an integer of 10 or greater, more than 0 and less than 1, and t is 0 or 1, and a sodium or potassium salt of 4,4'-diazidostilbene-2,2'-disulfonic acid represented by the general formula (IV), ##STR3## wherein z stands for sodium atom or potassium atom; or the resin represented by the general formula (I), the sodium or potassium salt of 4,4'-diazidostilbene-2,2'-disulfonic acid represented by the general formula (IV), and an aromatic ketone represented by the general formula (V), ##STR4## wherein G stands for hydrogen atom or an amino group or dialkylamino group represented by the general formula (VI), ##STR5## where u is 0, 1 or 2.
摘要:
A functional resin derived from a polyallylamine or polyvinylamine and having unsaturated C.dbd.C bonds such as allyl groups at terminals of side chains has good coating properties and strong adhesiveness to a substrate, thus can be used as protective films for various substrates, coating compositions and adhesives.
摘要:
In a process for producing a polymer of monoallylamine comprising polymerizing monoallylamine, the polymerization is carried out using as a monomer inorganic acid salts (e.g., hydrochloride, sulfate, etc.) of monoallylamine in the presence of an azo type radical initiator.By the process, polymers of monoallylamine having a high degree of polymerization can be obtained in high yield.
摘要:
A process for producing a novel photosensitive resin having cinnamic groups, comprising reacting a polyallylamine represented by the general formula (I) ##STR1## (wherein n is at least 10) or an inorganic acid salt thereof with a compound having a cinnamic group in the presence of a solvent. The process is free from drawbacks as experienced in the production of a conventional photosensitive resin (e.g. polyvinyl cinnamate), such as formation of by-products during the polymerization of a monomer (e.g. vinyl cinnamate).

A fluid bearing apparatus includes a housing 7 which has a cylindrical shape having a fixing face 7c for fixing the outer circumferential surface 8b of a bearing sleeve 8, and axial circulation grooves 7d for bringing both end faces 8c, 8d of the bearing sleeve 8 into circulation on the inner periphery by forging. A groove molding portion 18a2 is provided on the outer circumference of a rod 18 which serves as a forming mold for the inner periphery of the housing 7, and the circulation grooves 7d are formed by forging with this groove molding portion 18a2. Moreover, after a sealing face 107d and a cylindrical outer circumferential surface 107e provided on the outer periphery of the housing 107 are formed by forging, an inner circumferential surface 107c is formed by forging.

A motor 1 for traveling is attached to a frame 6 of a vehicle via mounts 3, 4 and 5 absorbing vibration. An air compressor 10 and an air compressor driving motor 11 are attached with respect to said motor 1 for traveling. The mounts 3, 4 and 5 are placed to be shared mounts absorbing vibration of the motor 1 for traveling, the air compressor 10 and the air compressor driving motor 11.
摘要:
A water saving device comprising a plate member which is sandwiched within and maintained within a joint portion of a tap water line and divides the tap water line across the line of water flow. A main body block is bolted to one side of the plate member along the axis of and positioned in the middle of tap water line. The plate and the main body block each has a plurality of water saving holes arranged circumferentially so that the number of opposing holes in the plate and the main body block which are aligned to allow water flow therethrough can be changed by relative rotation of the plate member with the main body block around bolt 13.
