A wiring substrate is provided with a support substrate (), an insulating layer (), and a wiring layer (). The support substrate () is formed with a hole () including an opening portion in one surface of the support substrate (). The insulating layer () is formed on a surface of the support substrate () opposite to the one surface thereof including the opening portion. The wiring layer () includes a wiring pattern of a predetermined structure on the insulating layer (). Further, an orthographic projection to be obtained when the wiring pattern is projected on a predetermined surface of the support substrate (), and an orthographic projection to be obtained when the hole () is projected on the predetermined surface of the support substrate () include a shared portion.

Wiring substrate and manufacturing method thereof

A system that affords synchronization signals for adjusting the skew in parallel transmission without producing data overhead to enable high-efficiency large-capacity transmission. On a transmitter side, a transmitter outputs two wavelengths. The transmitter transmits the data signals for transmission as it switches from a first wave length to a second wavelength at a certain synchronization timing. A wavelength filter separates a first wavelength and a second wavelength on a receiving side at the pre-stages of receivers receiving the data signals of the respective transmission paths. Data D and D , separated in association with the first and second wave lengths, are stored in buffers B , B to detect oncoming of data signals with maximum delay in the respective transmission paths. The data are output simultaneously from the second buffer B to the respective transmission paths in a timing of the data having the maximum delay.

Parallel transmission method and system

The present invention provide a pigment composition and a method for producing same at low cost, which has the same or more excellent quality compared with those produced by a salt milling process which has been commonly used. The pigment composition is produced by dry-milling a pigment in the presence of a surfactant and a water-soluble resin, said surfactant and said water-soluble resin being contained in amounts of 1 to 20% by weight and 2 to 50% by weight respectively based on an amount of the pigment. The pigment composition according to the present invention is readily dispersed into an aqueous system to obtain an aqueous pigment dispersion.

Pigment composition and aqueous pigment dispersion prepared therefrom

A process for the production of an aluminum phthalocyanine composition or a halogenated aluminum phthalocyanine composition in high yield and purity is provided which entails bringing a molten salt of aluminum chloride and/or aluminum bromide and a phthalocyanine compound having a central element other than aluminum into contact with each other in a predetermined temperature range thereby to substitute aluminum for the central element. Alternatively, the process involves conducting the aforementioned step, and introducing a halogen into the resultant reaction mixture.

Process for the production of aluminum phthalocyanine composition

A process for producing a polyhalogenated phthalocyanine containing not more than 0.02 part by weight of water-insoluble inorganic impurities derived from aluminum chloride per 100 parts by weight of phthalocyanine before halogenation, which comprises the following steps A, B and C;

Process for producing polyhalogenated phthalocyanine

A process for producing a pigment composition containing a highly halogenated copper phthalocyanine, produced by halogenation of copper phthalocyanine in the presence of chlorosulfonic acid, titanium tetrachloride or a mixture of titanium tetrachloride with aluminum chloride, a highly halogenated copper phthalocyanine produced by halogenation of a copper phthalocyanine in a solid powder state, or a highly halogenated copper phthalocyanine produced by cyclization. The composition further contains at least one highly halogenated different-metalo-phthalocyanine selected from highly halogenated metalo-phthalocyanines each of which has Al, Mg, Si, Ti, V, Mn, Fe, Co, Ni, Zn, Ge or Sn as a central metal.
