摘要： Disilane Si.sub.2 H.sub.6 is obtained with good yield by reduction reaction of Si.sub.2 Cl.sub.6 with a mixture of LiH and LiAlH.sub.4 in an organic liquid medium such as n-butyl ether. Usually the reaction temperature is -25.degree. C. to 50.degree. C. A suitable range of the mole ratio of LiH to LiAlH.sub.4 is from 0.8 to 40. It is impracticable to reduce Si.sub.2 Cl.sub.6 to Si.sub.2 H.sub.6 by using LiH alone as the reducing agent, but the reaction proceeds smoothly when a LiH/LiAlH.sub.4 mixture is used. The use of the mixture is economically advantageous over the use of expensive LiAlH.sub.4 alone.

摘要： A pattern memory for use in a thermal printer system stores a temperature-compensated pattern of a character to be printed on recording paper using a thermal print head having a plurality of heat-producing elements arranged in a single array is provided. The pattern is defined in the form of a dot matrix, each dot containing two or more binary data, each of which, if having a predetermined one of the two possible states, is associated with a predetermined activation time period for activating one of the heat-producing elements. The binary state of each of the two or more data in each dot is determined such that a level of heat produced by any of the heat-producing elements may be maintained at constant. In one embodiment having two binary data in each dot, the pattern is determined such that the one of the two data of a dot has "0" and the other has "1" if this dot is to be printed for a second time or more by the same heat-producing element in succession.
摘要翻译：在热敏打印机系统中使用的图案存储器使用具有排列成单个阵列的多个发热元件的热敏打印头来存储待印刷的字符的温度补偿图案。该图案以点阵的形式定义，每个点包含两个或更多个二进制数据，每个二进制数据如果具有两个可能状态中的预定的一个状态，则与预定的激活时间段相关联，以激活热中的一个生产要素。确定每个点中两个或更多个数据中的每一个的二进制状态，使得由任何发热元件产生的热量水平可以保持恒定。在每个点中具有两个二进制数据的一个实施例中，如果要将该点打印第二次或更多，则确定该点的两个数据中的一个数据为“0”，另一个具有“1” 由相同的发热元件连续地进行。

摘要： A thermal print head driving system supplies a predetermined number of driving pulses to each of a plurality of heat-producing elements arranged in a line to record a single dot of desired tone. The pulse width of driving pulse is controlled in accordance with the temperature at or in the vicinity of the heat-producing elements thereby allowing to maintain the density level of desired tone at constant. In another aspect of the present invention, it is so structured that driving pulses may be applied to the heat-producing elements in a continuous manner without producing a cooling period during switching between tone levels. In a further aspect of the present invention, it is so structured that a predetermined number of driving pulses for each of predetermined number of tone levels is altered in consideration of the data in at least one of preceding recording lines, thereby allowing to carry out a high speed recording operation without causing fluctuations in predetermined tone density level.
摘要翻译：热打印头驱动系统向排列成一行的多个发热元件中的每一个提供预定数量的驱动脉冲，以记录所需色调的单个点。驱动脉冲的脉冲宽度根据发热元件处或附近的温度来控制，从而允许将期望的色调的浓度水平保持在恒定值。在本发明的另一方面，其结构使得驱动脉冲可以以连续的方式施加到发热元件，而不会在音调电平之间切换期间产生冷却时段。在本发明的另一方面，其结构使得考虑到至少一个先前的记录线中的数据，改变预定数量的音调电平中的每一个的预定数量的驱动脉冲，从而允许执行高速记录操作，而不会引起预定的音调密度级别的波动。

摘要： A thermal recording system includes a thermal print head provided with a plurality of electrical resistors arranged in the form of a single row and selectively activated when an activation pulse is supplied, a brute supply for supplying a power supply voltage to the resistors and a pulse generator for controlling the duration of the activation pulse in accordance with the level of the power supply voltage actually applied to the resistors. The pulse generator controls the pulse width of the activation pulse so as to maintain substantially constant the activation energy defined as a product of (power supply voltage actually applied).sup.2 and (pulse width of activation pulse).
