Abstract: A vacuum forming method of forming a decorative film in close contact with a surface of an adherend in a forming space, by using a vacuum forming machine having the forming space seal-formed by a lower box and an upper box, includes: a pressure adjusting process of decompressing a lower division of the forming space sealed to have a lower pressure than an upper division of the forming space so as to produce a pressure difference between the divided forming spaces, thereby setting the pressure in the vicinity of the surface of the adherend lower pressure than that of the periphery thereof; a pressure releasing process of releasing the pressure difference after the forming process; and an extracting process of extracting a formed product. A lower end portion of the upper box is provided with a jig which suppresses lifting of the decorative film.

Abstract: A scrambling/descrambling apparatus has a data memory for storing a data word, a bit invert flag, and numerical data. A bit shift operating section performs, on receiving a bit of data to be outputted or a bit of input data, a bit shift operation with that bit and stores resultant data in the data memory in the form of a first data word. A randomizing/derandomizing section randomizes or derandomizes the input data by using the first data word and based on a generating polynomial and, depending on a state represented by the bit invert flag, inverts the bit of the data to be outputted to develop output data. A count processing section increments or decrements the numerical value stored in the data memory and, depending on the numerical value, selectively sets the bit invert flag to a predetermined state. A count controlling section replaces the numerical value with a predetermined initial value on the basis of the first data word and bit invert flag.
