Title: Production of oxytitanium phthalocyanine crystal
Inventor: TAKAGISHI IWAO
IPC: C09B67/50
Filed: 1991-02-01
Abstract: PURPOSE:To obtain the title crystal having a specified crystal form more easily and selectively than the prior-art process by bringing dichloro- or dibromo- titanium phthalocyanine into contact with a phenol and then with an organic solvent other than the phenol. CONSTITUTION:An oxytitanium phthalocyanine crystal is produced by bringing dichlorotitanium phthalocyanine and/or dibromo-titanium phthalocyanine into contact with a phenol and then with an organic solvent other than the phenol. This process is very advantageous for the production on an industrial scale because the oxytitanium phthalocyanine crystal of a specified crystal form can be obtained more easily and selectively than the prior-art process. The oxytitanium phthalocyanine obtained by this process has an excellent performance as a charge-generating material of an electrophotographic photoreceptor.

Filed: 1989-01-19
Abstract: PURPOSE:To obtain the regeneration signal small in lack of edges and distortion by providing a logarithmic stretcher to stretch an FM demodulating signal between an FM demodulator and a deemphasis circuit. CONSTITUTION:An FM demodulator 7 is provided to demodulate a reproducing FM signal and a logarithm stretcher 8 is provided to stretch the FM demodulating signal. Then, a deemphasis circuit 9 is provided to restore an output signal from this logarithm stretcher 8 to an original signal. Thus, at the time of reproducing, the signal to be FM-demodulated by the FM demodulator is inputted to the logarithm stretcher and stretched and after that, the signal is passed through the deemphasis circuit. Accordingly, since the signal is cut off by a clipper at the time of recording and a waveform, to which logarithm compression is executed, can be stretched, the reproducing signal of the small lack of the edge and small distortion can be obtained.

Filed: 1989-01-23
Abstract: PURPOSE: To obtain comparatively high contrast and luminance by arranging a gain reflector for reflecting light transmitted by a display medium to be varied between a light scattering state and a non-scattering state on the back of the display medium. CONSTITUTION: The display medium 12 consists of a material to be switched between the light scattering state and the non-scattering state and can display a picture with a high contrast ratio. The gain reflector 14 is used together with reference twisted nematic liquid crystal and guest/host liquid crystal and increases luminance in both the states of field impression and no impression. The effective rate of the reflector 14 depends upon the degree of parallelization of incident light, incident light to the reflector 14 in the non-scattering state is furthermore parallelized as compared with the scattering state and the effective gain can be increased more than '1'. Consequently high contrast and luminance is obtained.
