Abstract: When an input value is a standard value which is smaller than a maximum value (for example, 230), all pixels of a screen matrix is printed with the same output value (for example, 195), when the input value is within the range not more than the standard value, the output value is limited to not more than 195, and number of the pixels is changed so as to express graduation. In the range where the input value exceeds the standard value, the graduation is expressed by changing the output value of each pixel in the range above 195 while printing all the pixels of the screen.

Abstract translation: 当输入值是小于最大值（例如230）的标准值时，当输入值在该范围内时，屏幕矩阵的所有像素都以相同的输出值（例如195）打印 不超过标准值，输出值被限制在不大于195，并且像素的数量被改变以便表示刻度。 在输入值超过标准值的范围内，通过在打印屏幕的所有像素的同时改变195以上范围内的每个像素的输出值来表示刻度。

Abstract: A rod-shaped light guide includes an end face to which light is incident, a bottom plane on which a scattering pattern to scatter light incident to the end face is formed, and a light emitting portion located to be opposite to the bottom plane and emitting light outside. The light emitting portion is formed as a first plane and a second plane connected to each other. The first plane is formed to be smaller than the second plane so that the cross section thereof perpendicular to the longitudinal direction is asymmetrical.
