Abstract: An image recording method and an image recording apparatus using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the image recording method, the ink is subjected to a pattern of pH change to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the pH change pattern.
Abstract: A laminated window is prepared by applying an ultraviolet curable acrylate resin to a transparent rigid outer layer. The acrylate is carried in a solvent that swells a plastic surface of the outer layer to promote adhesion. After evaporating substantially all of the solvent the base coat is exposed to ultraviolet radiation to polymerize the acrylate. An electrically conductive metal layer is deposited on a portion of the base coat. When this is completed the window may be laminated with a conventional interlayer and rigid transparent inner layer.

Abstract: The invention is directred to an electric heating in a bread toaster, comprising an insulating body (11) and heat conductor portions (14, 14') which may be arranged on both the front part and the back of the insulating body (11) and are pressed thereagainst by mounting strips (21). To compensate for uneven browning of the article to be toasted--which is caused by the bread toaster being cooled by an air current entering at its bottom and subsequently flowing mainly in the area of the center axis (X) of the insulating body (11)--, it is suggested to provide the mounting strips (21) on the insulating body (11) spaced from one center aixs (X) and thus substantially outside the range of action of the air current.
Abstract: The present invention relates to the field of electro-thermal conversion material and its products, made by semiconductor material. The process of making the electrothermal conversion material is as follows: a liquor is composed by dissolving two kinds of chloride (tin tetrachloride, etc.) in ethyl alcohol or carbinol, and another liquor, ammonium fluoride. After atomization of these two liquors, under the condition of high temperature, high valent metal oxide, low valent metal oxide and metal single substance etc, the metals of which correspond to the two kinds of chloride, deposit onto the surface of the high-temperature-resistant insulating material, forming a conductive semiconductor membrane.
Abstract: A variable resistor whose resistance is adjustable by rotating a rotor on an insulating substrate having an arcuate resistive element. The rotor is formed of an insulating resin and includes an inner skirt and an outer skirt extending from a bottom surface thereof. The inner skirt contacts the upper surface of the insulating substrate inside the arcuate resistive element. A metallic slider is integrated with the rotor by insert molding. The slider comprises a base formed of a metal plate folded at least into two, and arms having contacts at the tips thereof for slidably contacting the resistive element on the insulating substrate. The arms are folded along lines which are parallel to a line extending from the center of the base to the contacts of the arms to cause the contacts to project toward the insulating substrate. One of the metal plates forming the base cooperates with the inner and outer skirts of the rotor to seal a space accommodating the resistive element and the arms of the slider.
Abstract: Information is recorded with one or more elongate thermal recording heads on a recording medium advancing at least intermittently on a recording medium support. Such recording head or heads are being pressed against the recording medium at the recording medium support by at least two biasing devices spaced along such elongate thermal recording head or heads. These two biasing devices are balanced relative to each other opposite the elongate thermal recording head or heads, as seen from the recording medium support. Different characteristics of the biasing devices are thus compensated opposite the elongate thermal recording head or heads, as seen from said recording medium support. Forces acting at one end of an elongate thermal recording head, or acting on one of the recording heads, against either of the biasing devices are transmitted via both biasing devices to an opposite end of that elongate thermal recording head or to the other of two elongate thermal recording heads.

Abstract: An image forming apparatus makes use of a photosensitive sheet having a surface coated with microcapsules encapsulating a light-curable agent and a colorless dye and an image transfer sheet having one surface coated with a developing agent having an chromogenic effect on the encapsulated colorless dye. When these sheets are superposed one on top of the other and transported to and pressed together between a pair of pressure rollers, the image transfer sheet is transported to the pressure rollers by making an angle greater than 0.5.degree. with the axial direction of these rollers.

Abstract: A thermal printing head in accordance with the present invention has a substrate formed of an electrical insulator, heating elements formed on the substrate, and conductive layers formed on the part of the heating elements that is adjacent to and on either side of heat generating portions of the heating elements. The resistivity of heating elements is set at a value of not less than 1000 .mu..OMEGA..cm and, simultaneously, the thickness of conductive layers is set at a value of not more than 300 nm. By virtue of this arrangement, it is possible to reduce the distance between the heat generating portions of the head and the printing paper or ink sheet, and the thin conductive layers contribute to minimizing diffusion of the heat. The thermal printing head is therefore capable of efficiently and accurately transferring heat generated by the heat generating portions to the printing paper or ink sheet.
Abstract: This is a structure of, and method for preparation of, molybdenum resistors in a superconductor integrated circuit. It utilizes a pattern superconductor film; applying an aluminum film on the patterned superconductor film; and then applying a molybdenum film on the aluminum film to provide an aluminum-molybdenum, etch-stop interface; applying a patterned resist film on the molybdenum film; etching the exposed molybdenum film to expose a portion of the aluminum-molybdenum, etch-stop interface; and oxidizing the exposed aluminum-molybdenum, etch-stop interface. The aluminum-molybdenum etch stop interface protects the patterned superconductor film and the support (including any other underlayers) and increases processing margins for the etch time.
Abstract: A compact, handy type facsimile machine includes a light source for illuminating an original, a line image sensor for optically reading the original, a condensation sensor for detecting formation of water droplets by condensation on the image sensor, and a control circuit for activating the light source when the condensation sensor has detected the formation of water droplets by condensation on the image sensor. Thus, upon occurrence of condensation, the condensation sensor generates a detection signal, and, in response thereto, the light source is lit to produce heat which then causes the water droplets formed on the image sensor to disappear. Upon disappearance of such water droplets, the control circuit deactivates the light source if there is no original to be read.
