Title: Thermal head
Inventor: ITOU HIROSHI
IPC: B41J2/35
Filed: 1984-03-13
Abstract: PURPOSE:To prevent possible uneven printing density by making the resistance value distribution of heating resistors lower gradually away from the power source of the common electrode. CONSTITUTION:In a plurality of heating resistors divided into blocks each 224 pieces, the resistance value distribution of the heating resistors 51-5n is made lower gradually away from terminals 2a and 2b, that is, toward the center thereof as shown by the solid line (d). An electrode conductor 2 is formed by thick film technology or thin film technology. On the other hand, the heating resistors 5 is also formed by employing the widely accepted conventional thick film technology or thin film technology. In the case of a thick film type thermal head, printing conditions of a resisting paste are changed to make the width of the heating resistors 51-5n larger toward the center. In the case of a thin film type thermal head, a so-called one-point radiation is done with an evaporation source brought closer to an insulating substrate in the sputtering to make the amount of evaporation larger toward the center.

IPC: F16L1/00
Filed: 1993-02-15
Abstract: PURPOSE:To prevent a synthetic resin pipe adapted to be inserted in a pipe line so as to form an inner pipe, from being deformed, and to enhance the pressure resistance by holding the pipe in a flat folded condition before it is inserted into the pipe line so as to prevent the pipe from being formed in a permanent recess-like cross-sectional shape. CONSTITUTION:In order to manufacture an inner pipe in a pipe line, at first a pipe 5 made of a hard thermoplastic synthetic resin and extrusion-molded in a cylindrical shape, is folded in a flat shape at a temperature around the viscut softening temperature of the resin. Then, the pipe 5 is then heated up to a temperature which is sufficiently lower than the viscut softening point and at which the pipe 5 may be deformed, so as to be curved into a V-like or U-like cross-sectional shape while the flat-folded condition is sustained. Then, the curved pipe 5 is inserted into the pipe line 9, and is heated up to a temperature higher than the temperature at which the pipe 5 is curved while an internal pressure is effected so as to inflate the pipe 5 in order to from an inner pipe in the pipe line 9. With this arrangement, the pipe 5 is held in a flat folded condition just before the insertion of the pipe 5 into the pipe line 9. Thereby it is possible to eliminate such a problem that the pipe 5 is formed in a recess-like cross-sectional shape.

Abstract: PURPOSE:To offer the method of forming a direct contact, by which a silicon semiconductor substrate is not shaved when a polycrystalline silicon layer constituting the direct contact is etched. CONSTITUTION:The formation method of a direct contact adopts a system that a blocking layer consisting of a high-melting point metal layer is installed on an oxide layer superposed on one part of a selective oxide layer for isolation use for preventing an electrical continuity from being stopped by forming a recess or the like due to anisotropic etching, for example, between an impurity diffused layer, which is generated along the surface of a semiconductor substrate to be formed with an element aiming at a high-speed efficiency like a Bi-CMOS integrated circuit, and a channel layer, for example. Thereby, as the recess which is formed in an insular region at the time of the etching can be prevented from being formed and a continuity of the impurity diffused layer is ensured, the characteristics of the element which adopts a shallow junction system can be reliably guaranteed.

A layer of oxides of three alkaline earth metals, which contains the same oxides as the former layer and contains 0.05-1wt% of ZrC, is provided on the layer 2. The Ni, Co or the like is thus added to the layer 2 to prevent its electric conductivity from falling due to SiO2, MgO or the like produced by the reduction of the alkaline earth metal oxide. The ZrC reduces the alkaline earth metal oxides on the boundary of the layer 2 and the latter alkaline earth metal oxide layer to emit enough electrons. A cathode of higher performance than a conventional cathode is thus provided for a television cathode-ray tube or the like.
