Title: Corrosion preventive method for pipeline
Inventor: KOBAYASHI RYOJI
IPC: B05D7/22
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent corrosion of pipelines with a resin coating base on a corrosion preventive function and cost performance without unifying coating materials by coating each single pipe before assembly of pipes into pipelines with a thermoplastic resin-based material and coating pipelines after pipes are assembled into pipelines with a reactively curable resin-based material. SOLUTION: The inner face of a SGP pipe 1 is blast-treated and coated with polyethylene in about 1.5mm thickness and in this case, 150mm ranges from both tip ends of the pipe are not coated. Two of such steel pipes 1 are produced and a pipeline is manufactured by connecting these two pipes by welding 4 and at that time, the steel material faces in the peripheral areas of the exposed welded parts 4 are treated by a grinder for surface preparation and further, 100mm ranges of the end parts of the inner faces coated with the polyethylene coating 2 are treated with flames to polarize their surface. After that, a thermosetting resin-based coating 3 in about 1.5mm thickness is formed in the peripheral areas of the welded parts 4 by using an epoxy resin coating material as a reactively curable resin-based coating material to complete corrosion prevention treatment.  It is preferable that 5-35vol.% of aggregate is added to the reactively curable resin-based material.

Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To restrain consumption of a current by switching one apparatus into another frequency if one frequency is used on the other apparatus for a fixed time. SOLUTION: The powers of receiving circuits 31 and 32 are turned on by interruption at an interval of five seconds by a CPU 37 for example, and whether a frequency A is received by the frequency A receiving circuit 31 or a frequency B is received by the frequency B receiving circuit 32 is judged. Then, whether an ID number received at the frequency A receiving circuit 31 and a user code previously set to the CPU 37 are identical is decided, and when it is decided 'NO', whether the same frequency is received for 24 hours is decided. Then, if it is judged 'YES', switching of frequency is performed. For example, when a state where the frequency A is received via the frequency A receiving circuit 31 but the ID numbers are unmatched is continued for 24 hours, a processing for switching the receiving circuit from frequency A into frequency B is conducted.  In this case, frequency switching circuits 33 and 36 are actuated by a ommand from the CPU 37.

Title: Formation of resist pattern
Inventor: SHIOBARA HIDESHI
IPC: H01L21/027
Filed: 1993-09-10
Abstract: PURPOSE:To obtain a pattern excellent in the dimensional stability in which the trailing of skirt is eliminated on the interface with the underlying layer by forming an antireflection film containing a substance producing an acid on a substrate through irradiation of light, and then forming a chemical amplification resist film of a resin provided with a dissolution retardant and a substance producing an acid thereon through irradiation of light. CONSTITUTION:A photosensitive antireflection film 2 containing an acid producing agent is formed on an underlying substrate 1 and then bridges are formed thermally so that it is not dissolved into a resist. A chemical amplification resist film 3 is then formed thereon and irradiated with an exposing light 4 through a mask 5. Consequently, an acid 6 is produced in the exposed region 3a on the resist film 3 and the underlying antireflection film 2. Subsequently, PEB is effected at a temperature for providing a sufficient sensitivity without decomposing a dissolution retardant and the previously produced acid is diffused into the resist film within the exposed region thus setting a solubility contrast for the developer between the exposed region 3a and unexposed region 3b. Finally, the resist film 3 is removed from the exposed region 3a through development.

Title: Picture processing controller
Inventor: KUSAKAWA MARI
IPC: H04N1/415
Filed: 1993-09-10
Abstract: PURPOSE:To utilize picture data compression processing capability of the controller optimizingly by allowing a control means to control the compression processing so as to change picture quality of a compressed picture depending on a degree of a load of a picture processing means. CONSTITUTION:A picture processing section 1 writes a value of a picture quality control parameter in response to a picture processing request number stored in a current picture memory 2 to a setting register 31 and writes it to a compression table 36 of a compression processing section 35. The processing section 35 decides a designated value of a picture processing queue corresponding to the designated value set as the initial value of the register 31 and compares it with a current picture processing request number. When they are coincident, the parameter is used to process the picture. When the processing request number is less than the designated value, the processing speed is reduced to improve the picture quality of the compressed picture and when the processing request number is more than the designated value, the picture quality control parameter is changed to improve the processing speed regardless of degrading of the picture quality. Thus, the compression processing capability is utilized optimizingly corresponding to the degree of the load.

Title: Optical scanner
Inventor: NIIKURA ISAMU
IPC: G02B5/09
Filed: 1983-11-30
Abstract: PURPOSE:To make scanning light exact and stable without using optical members having high accuracy by providing a right-angled reflection mirror on the front face of a rotary polyhedral mirror to which the ray from a light source is made incident thereto in parallel with the axial center. CONSTITUTION:The laser beam projected from a laser light source 5 is first reflected by reflecting face 1 of a rotary polyhedral mirror 2 and is then successively reflected by the reflecting faces 6, 7 of a right-angled reflection mirror 8. The beam is further reflected again by the same face 1 and is then condensed by a condenser lens 9 so that a spot 11 scans a surface 10 to be irradiated. When the revolving shaft 3 of the mirror 2 inclines, the laser beam from the source 5 changes in the reflecting direction. The incident light and the reflected light are parallel on the mirror 8 in this stage and therefore the laser light reflected again by the face 1 is made incident in the parallel state with the light projected from the source 5 to the lens 9. The spot 11 is therefore focused at the same point on the surface 10. The scanning light is thus made exact and stable without using optical members having high accuracy.
