    • A prediction error calculation part calculates a prediction error for each input data. A prediction error encoding part generates a prediction error code by encoding the value of the prediction error. A run-length counting part counts the run-length of the prediction error. When the value of the prediction error changes, a run-length encoding part generates a run-length code by encoding the run-length counted. A code connecting part generates a connected code by connecting the run-length code to the prediction error code of a corresponding prediction error. When the value of the prediction error is a particular value, a prediction error checking part selects a connected code for the prediction error, as an output code. When the value of the prediction error is a different value, the prediction error checking part selects a prediction error code for the prediction error, as an output code. A code output part outputs the output code selected.
    • 预测误差计算部分计算每个输入数据的预测误差。 预测误差编码部分通过对预测误差的值进行编码来生成预测误差码。 运行长度计数部分计算预测误差的运行长度。 当预测误差的值改变时,游程长度编码部分通过对所计数的游程进行编码来生成游程长度代码。 代码连接部分通过将游程长度代码连接到相应的预测误差的预测误差代码来生成连接的代码。 当预测误差的值是特定值时,预测误差检查部分选择用于预测误差的连接代码作为输出代码。 当预测误差的值是不同的值时,预测误差检查部分作为输出代码选择预测误差的预测误差代码。 代码输出部分输出所选择的输出代码。

    • A resin product has a body made of a resin. The body has an outer surface including an ornamental surface and an unornamental surface, a first area defined on the outer surface, and a chemical plating layer and an electroplating layer respectively formed on the first area. A process for producing the resin product comprises the step of making a first boundary along a contour of the first area located on the ornamental surface, and the step of making a second boundary along a contour of the first area located on the unornamental surface. The step of making the second boundary includes forming a resist layer on the unornamental surface. The resist layer has a resistivity to a chemical plating solution for making the chemical plating layer. The process also includes the step of forming the chemical plating layer on the outer surface of the body except a part of the first boundary and the resist layer by chemical plating the body, and the step of selectively forming the electroplating layer on the chemical plating layer within the first area.

    • Contoured step sections and contoured grooves along the step sections are formed on a grille body. The grille body is subjected to chemical plating. Since the grooves have narrow bottoms, the bottoms remain unplated, so that a chemical plating layer is formed on the entire surface of the grille body except for the bottoms. The grille body having the chemical plating layer formed thereon is then subjected to an electroplating step having a plurality of steps. An undercoat plating layer is formed on the chemical plating layer formed on the portions where decorative plating is to be applied. The chemical plating layer formed on the portions where no decorative plating is to be applied is dissolved with a predetermined solution. Subsequently, a general electroplating layer is formed on the undercoat plating layer. Thus, the chemical plating layer and the electroplating layers are formed only on the to-be-plated portions. The plated portions are covered with an electroforming mask, and a coating is applied onto the exposed portions to form a coating layer, where the edges of the electroforming mask can be registered with the edges of the plating layer. Accordingly, the boundaries between the coating layer and the plating layer can clearly be defined.
    • 在格栅体上形成沿着台阶部分的轮廓台阶部分和轮廓的凹槽。 格栅体进行化学镀。 由于凹槽具有窄的底部,底部保持未镀层,所以除了底部之外,在格栅体的整个表面上形成化学镀层。 其上形成有化学镀层的格栅体然后进行具有多个步骤的电镀步骤。 在形成在要施加装饰性电镀部分的化学镀层上形成底涂层。 用规定的溶液溶解在不施加装饰电镀的部分上形成的化学镀层。 随后,在底涂层上形成一般电镀层。 因此,化学镀层和电镀层仅形成在被镀层部分上。 电镀部分被电铸掩模覆盖,并且将涂层施加到暴露部分上以形成涂层,其中电铸掩模的边缘可以与镀层的边缘对准。 因此,可以清楚地限定涂层和镀层之间的边界。
