##STR1## (wherein R 1 and R 2 independently stand for at least one member selected from the class consisting of alkylene groups, substituted alkylene groups, cycloalkylene groups, substituted cycloakylene groups, arylene groups, and substituted arylene groups), is a novel diacetylene-nylon salt compound possessing two kinds of ability of solid-state polymerization, and two-dimensional macromolecular crystals are obtained by severally polymerizing the diacetylene moiety and the nylon salt moiety of the compound. A shaped article of hig rigidity is produced by filling a mold with the aforementioned salt and subjecting the salt in the mold to simultaneous application of heat and pressure.

摘要:
Cyanometallophthalocyanine crystals which are organic electroconductive crystals are produced by electrolysis of an electrolyte containing an alkali salt of dicyanometallophthalocyanine. Organic electroconductive crystals of better quality are produced by causing the cyanometallophthalocyanine crystals mentioned above to incorporate therein an electron accepting compound and an electron donating compound as doping substances.
摘要:
A thickness determination method for organic films comprises the steps of: irradiating an organic film to be measured with x-rays at a certain angle of incidence, finding an angle of reflection at which the x-ray intensity reaches a peak, and finding the thickness of the film from the angle of this peak.
摘要:
Disclosed is a novel aromatic ester compound represented by the general formula ##STR1## in which Pn is a 1,4-phenylene group, R.sup.1 is an alkyl group having 1 to 4 carbon atoms, R.sup.2 is a group selected from the group consisting of perfluoroalkyl groups having 1 to 4 carbon atoms, cyano group, nitro group, 2,2-dicyanoethenyl group and methylsulfonyl group and the subscript n is a number of 2, 3 or 4. These aromatic ester compounds are useful as a second-order non-linear optical material in the ultraviolet wavelength range so that a resin film containing the compound has a good second-order non-linear optical coefficient d.sub.33 of 2-4.times.10.sup.-9 esu.

A polymeric nonlinear optical material is produced by mixing a polyelectrolyte solution with an ionic pigment solution thereby obtaining a solution containing a composite of said polyelectrolyte and said ionic pigment, and separating said composite from said solution.
摘要:
A printing apparatus includes a plurality of inkjet print heads to which humidified air is supplied to retain the humidity in the print heads. Ink colors for the plurality of heads are arranged in a sequence corresponding to ink characteristics. The plurality of print heads are arranged in a sequence such that a print head configured to eject ink characterized by having a larger amount of volatile components evaporated within a predetermined time is located in a more upstream area.
摘要:
A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.
摘要:
A recording apparatus comprises a writing unit adapted to write data on a recording medium, a selection unit adapted to select data to be written on the recording medium from a storage medium configured to store a plurality of data, and a display control unit adapted to cause a display device to display a display screen concerning printing before the data selected by said selection unit is copied from the storage medium onto the recording medium, wherein said display control unit causes the display unit to display the display screen if there is a restriction on the number of times of copying of the data.
