摘要： PURPOSE:To attain drying at an average speed for the entire part at the drying process after rinsing by providing a pseudo pattern provided to a close contact type line sensor to a thin wiring pattern pattern so as to eliminate dense and thin parts of the pattern thereby uniformizing the pattern. CONSTITUTION:A pseudo pattern 4 is formed by means of the lithography technology being the known pattern forming method by using the same mask pattern as for a conductor thin film layer 12 and a lower electrode pattern and a wire pattern 3 for a picture element 1 formed in advance on an insulation substrate 6. Through the constitution above, a chevron shaped pseudo pattern, in this embodiment, is formed between wiring pattern groups 3 at both ends of each drive system IC 2 and all patterns are formed dense other than the surrounding of the picture element 1. Thus, the residua at drying are moved from the surrounding to the pseudo pattern and the residua around the picture element (lower electrode) are remarkably reduced in comparison with the case without the pseudo pattern.

摘要： PURPOSE:To prevent the quality of a picture from deteriorating by forming an adhesive layer made of any of molybdenum, titanium, nickel, chromium or their alloy on the uppermost layer of a common electrode in contact with a wear resistant protective layer. CONSTITUTION:After many heat generating resistors 21 and wirings 30 are formed in one row in a direction perpendicular to this sheet face on the high resistance board 10 of a heat sensitive recording head, a protective layer 40 is formed, four layers of lower layer chromium 51 having good adhesive properties with a lower layer metal, copper 52 of one of solder connecting metal layers, gold 53 for improving solderability by preventing the surface of the copper from oxidizing, and an upper layer chromium 54 having satisfactory adhesive properties with the gold and silicon nitride are formed by a sputtering method continuously in the same chamber, and a common electrode 50 to be connected to external wirings and a heat generating resistor driving IC connecting electrode 60 are formed. As a result, even after a silicon nitride film 71 of a common wear resistant protective layer is formed on the electrode 50 and the resistor 21 by a plasma CVD method, it can prevent the film 71 on the electrode 50 from peeling and prevent the quality of an image from decreasing.

摘要： PURPOSE:To permit the density of color to be controlled by the amount of energy charged in thermal transfer recording by providing plural heating resistors, capable of forming one dot and having different widths, connected in parallel. CONSTITUTION:A resistor 2 consists of plural resistors 21, 22, 23, 24, and 25 which are connected in parallel. The central resistor 23 of resistor 2 is made wider and the resistors on both sides are made narrower. When direct current is applied across electrodes 1, the current flows in a concentrated manner in the central portion in an early stage and as time passes color region is widened by the heating of sides. By the combined use of the increase on decrease in color or transfer regions and the gradation of area, a gradation can be obtained without lowering resolution.

摘要： PURPOSE:To achieve both clear image quality and prolonging the useful life of heating resistors, by a method wherein an electric current passed to heating resistors for developing the color of a thermal recording paper is divided into a plurality of parts for recording of a single dot, and a current passing time for the first section is set to be longer than that for the other sections. CONSTITUTION:The electric current passed to the heating resistors is divided into several - several tens of parts, and the current passing time for the first section is set to be longer than that for the second and later sections. Preferably, for example, the current passing time for the first section is set to be 0.25ms, and thereafter, an OFF period of 60mus and an ON period of 20mus are repeated 9 times. Accordingly, the curve of the temperature of the heating resistors against the current passing time becomes trapezoidal in shape, so that the maximum temperature reached can be lowered, as compared with that for a triangular temperature curve obtained in conventional cases of a single passage of electric current.
摘要翻译：目的：为了实现清晰的图像质量和延长加热电阻器的使用寿命，通过一种方法，其中传递到用于显影热敏记录纸的颜色的加热电阻器的电流被划分成用于记录单个点的多个部分并且将第一部分的电流通过时间设置为比其他部分的电流通过时间长。构成：传递到加热电阻器的电流分为几十个部分，第一部分的电流通过时间设置为比第二部分和后续部分的电流通过时间长。优选地，例如，将第一部分的电流通过时间设定为0.25ms，此后重复9次关闭周期为60mus，ON周期为20mus。因此，加热电阻器的温度相对于电流通过时间的曲线在形状上变为梯形，从而与单次电通过的常规情况下获得的三角温度曲线相比，达到的最高温度可以降低当前。

摘要： PURPOSE:To solve the difficulty of pattern alignment and improve the yield of thermal heads by providing dimensional allowances to the patterns of a heating element forming photo mask and the patterns of an electrode forming photo mask. CONSTITUTION:A Ta2N film is formed on a high resistance substrate and photo resist is exposed by using a heating resistor forming photo mask of a pattern width W1 and integroove spacing G1, whereby the shaded light transmission parts are sensitized. When the resist is removed after the etching, the Ta2N film remains as the patterns of the heating resistors 3 as shown by shaded line. Next. a NiCr-Au film is evaporated thereon and the photo resist is exposed by using an electrode photo mask of a pattern width W2 smaller than the width W1 and of an interpattern spacing G2 smaller than the spacing G1, whereby the shaded light transmission parts are sensitized. When the resist is removed after the etching, the NiCr-Au film remains like the shading as the patterns of the electrodes 4, whereby the heating resistor patterns and lead wire patterns are formed.
