摘要： PROBLEM TO BE SOLVED: To enable the surface treatment for modifying, by using ions, the inside surface of a pit formed in a part (e.g. a bearing of a small-size motor) to be easily, efficiently, and stably conducted. SOLUTION: The inside surface 4b of the pit 4a arranged apart from an ion introduction end is subjected to a surface treatment by introducing ions into the pit 4a while at least a part of the pit 4A is kept blocked up. Ions incident into the pit 4a accumulate on the surface of an insulating material 10. As a result, the electric field becomes large, and since newly incident ions, after reaching the vicinity of the surface of the insulating material 10, are led to the inside surface 4b, the collision ratio of ions to the inside surface 4b becomes high.

摘要： PROBLEM TO BE SOLVED: To prevent any bit column which is the same as a frame synchronizing code (m bits) from being generated, even when performing XOR arithmetic operations with a scramble code, when the frame synchronizing code is used from the scramble code, and to obtain secrecy of data by sharing the scramble code by a transmitter and a receiver. SOLUTION: A transmitter 1 and a receiver 21 are respectively provided with a synchronizing code storing means 2 and 22 for storing m-bit frame synchronizing codes and scramble code generating means 3 and 23 for generating scramble codes from the frame synchronizing codes. The transmitter 1 performs exclusive OR operation on the transmission data added with an error correction code using a BCH (n, k) code by using the scramble code, and outputs a transmission signal. At this point, the code length of the scramble code is set so as to be made equal to the code length n of the BCH code.

摘要： PROBLEM TO BE SOLVED: To obtain a color wheel device to be used for an image generating device and having filter segments less in wind-ripping pound and free from being damaged even in a ultrahigh rotation state. SOLUTION: In the color wheel device, interference filters are applied (by forming films) on the front and back faces of a disk type single substrate so as to constitute the filter segments by the synthesis of the interference filters on the front and back faces. The obtained color wheel produces little frictional sound with air and is safe by eliminating the level difference on the seams on the substrate.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of the same bit stream as that in a frame synchronization code even when a scramble code and data are XORed in the case that the frame synchronization code (in m-bits) is used for the scramble code and to obtain the secrecy of the data by allowing only a transmitter and receiver to share the scramble code. SOLUTION: Each of the transmitter and the receiver is provided with a synchronization code storage means that stores the frame synchronization code in m-bits and with a scramble code generating means that generates a scramble code from this frame synchronization code, and the transmitter applies an exclusive OR arithmetic operation to transmission data with an error correction code employing BCH (n, k) code added to them by using the scramble code and outputs a transmission signal. In this case, a code length (m) of the scramble code is set to be equal to the code length (n) of the BCH code.

摘要： PROBLEM TO BE SOLVED: To reduce dust generated by the exposure of a film deposited on a deposition preventive board to plasma and to improve the yield of the device by allowing only the part remarkable in the increase of temp. in the deposition preventive board with a jacket structure and introducing high temp. liq. therein. SOLUTION: A deposition preventive board 12 is loaded around a substrate 1 and a planar target 2 in such a manner that a film is not deposited on a chamber 8. The deposition preventive board 12 has a cooling jacket part 16, and in which high temp. liq. can be introduced. Desirably, the lower limit of the temp. of the liq. to be introduced is controlled to 50 deg.C, and the upper limit is controlled to 80 to 85% of the decomposing temp. of the material of the planar target 2. Hot water heated at 70 deg.C is introduced into the cooling jacket part 16, and reactive gas such as argon and oxygen is introduced therein via a valve 7. With zinc sulfate+quartz weak in bonding strength as the planar target 2, discharge is executed by high frequency magnetron sputtering. Since its temp. does not reach the decomposing temp. of the material owing to the cooling effect, the film stuck to the deposition preventive board 12 is not decomposed, the desorption of the film caused by film stress and thermal stress is reduce as well, and dust is reduce.

摘要： PROBLEM TO BE SOLVED: To surely transmit information from a center to an information terminal in a house. SOLUTION: This system is equipped with a radio equipment slave machine A11 which communicates information by a radio connected to facility equipment 10 installed outdoor, an information terminal 12 equipped with a radio equipment slave machine B13 which is provided in a house and communicates with the facility equipment 10 by the radio, and a radio equipment master machine 9 which performs information communication by a radio circuit with a radio equipment slave machine A connected to the facility equipment 10. Thus, since it is possible to bidirectionally communicate with a center without depending upon kinds of wire communication line at a user house such as an analog telephone line, a digital telephone line, a CATV or no telephone line, it is possible to surely transmit an information message from the center to an information terminal of the house.

摘要： PROBLEM TO BE SOLVED: To improve the uniformity of the thickness of a film on a substrate and to prolong the service life of a target by oppositely arranging a substrate and a planar target in a film forming chamber, placing their centers on the same axis and introducing sputtering gases from plural gas introducing ports therein in such a manner that the amounts thereof to be introduced are respectively controllable. SOLUTION: In a chamber provided with a chimney 16 for preventing sticking and connected to a vacuum pump 8, a circular substrate 1 and a planar target 2 are oppositely arranged, and the respective centers are placed on a center axis C. This chamber 7 is provided with sputtering gas introducing ports 18 at >=3 places, from which sputtering gases are introduced through mass flow controllers 5' and 5" and valves 6' and 6". Then, voltage is applied from a high voltage power source 10 to an electrode 9 provided with a magnet placed with a target 2. In this way, plasma is generated, and the target 2 is sputtered to form a thin film on a substrate 1. At this time, while flow rate set value in the mass flow controllers 5' and 5" is changed from the initial stage of the use of the target 2 to the end of the life, the amounts of the gases to be introduced are controlled.
