The invention discloses a novel radiation-curable silicone-based release coating composition capable of giving a cured release coating film on a substrate such as a plastic resin film exhibiting excellent adhesion to a variety of substrate materials and excellent releasability. The radiation-curable releasing silicone composition of the invention comprises (A) an aromatic compound having, in a molecule, at least two cationically polymerizable organopolysiloxanyl groups such as epoxy-substituted organopolysiloxanyl groups as the silicone ingredient and (B) a photopolymerization initiator which is an onium salt compound such as diaryliodonium salt compounds.

An ink jet recording head in which a heating resistor forming a heating portion, a wiring electrically connected to the heating resistor, and a protective film formed on the heating resistor and the wiring to protect the heating resistor and the wiring are arranged on a substrate for the ink jet recording head. An ink path in communication with a discharging port for discharging ink is also formed on the substrate for the ink jet recording head. The protective film includes a first protective film layer for covering the heating resistor and the wiring, a second protective film layer formed on the first protective film layer by a material different from that of the first protective film layer and having an opening in a portion corresponding to the heating portion of the heating resistor, and a third protective film layer constructed of the same material system as the first protective film layer and covering the second protective film layer and the portion of the first protective film layer that is exposed through the opening. The second protective film layer is constructed of an inorganic material.

A substrate for use in an ink jet recording head is provided with a plurality of heat generating members for generating thermal energy to be utilized for discharging ink. The heat generating members are structured by a thin film formed by material represented by Tax Siy Rz, which has a specific resistance value of 4000 &mgr;&OHgr;·cm or less, where R is one or more kinds of elements selected from/among C, O, N, and x+y+z=100. With the structure thus arranged, the heat generating members make it possible to maintain the change of resistance values within a small amount even when used continuously for a long time, and provide recorded images of high quality with long life and reliability.

A printing head according to the present invention resets the count value of a counter in response to an externally supplied signal, and thereafter, counts a signal supplied upon input of an image signal. A decoder generates a selection signal in accordance with the count value, thereby selecting a divided heat-generating element group in units of 32 clocks. Furthermore, an electric current is supplied to heat-generating resistors which belong to the selected heat-generating element group, thereby performing a printing operation. With this printing head, a printer, which can be controlled by a smaller number of control signals, can be realized.

Proposed is an improved aqueous silicone emulsion composition for surface-release treatment comprising a vinyl-containing organopolysiloxane and an organohydrogenpolysiloxane emulsified is an aqueous medium with addition of a platinum compound as a catalyst for the hydrosilation reaction between the silicon-bonded vinyl groups and silicon-bonded hydrogen atoms. Different from conventional silicone emulsion compositions of this type having a pH value of around neutrality, the inventive silicone emulsion composition has a pH value not higher than 5 so that a quite unexpected advantage can be obtained that the stability of the emulsion composition in the curability and other properties after a long period of storage and against mechanical working can be greatly improved.

In an information signal reproducing apparatus having a reproducing head for reproducing information signals from recording tracks formed on a record bearing medium and a shifting device for shifting the reproducing head athwart the tracks, the shifting device is arranged to be operatable in a first operating mode in which the reproducing head is shifted to a predetermined extent for every first predetermined period and also in a second operating mode in which the reproducing head is shifted to the predetermined extent for every second predetermined period which is longer than the first period. The shifting device is controlled not on the basis of the output of the reproducing head in the first mode but on the basis of the output of the reproducing head in the second mode.
