Title: Polyolefin coated aluminum alloy laminate
Inventor: NAGURA TAICHIRO
IPC: B32B15/08
Filed: 1987-09-22
Abstract: PURPOSE:To increase adhesive propertied and corrosion resistance between respective layers by flame spraying pure aluminum to a rough surface treated aluminum alloy layer and then treating the pure aluminum layer with alkali, and then coating the same with a polyolefin layer. CONSTITUTION:Pure aluminum is flame sprayed to a rough surface treated aluminum alloy layer, and then polyolefin is applied on said alkali treated pure aluminum layer to form an aluminum alloy laminated material coated with polyolefin. Since uniform coating is difficult if the coating thickness formed by spraying pure aluminum is too thin, it is proper to make the thickness of 50-200mum. The alkali treatment of the pure aluminum layer can be carried out by, for instance, immersing the pure aluminum layer into caustic soda solution. Coating the pure aluminum layer with polyolefin can be carried out by the polyolefin extrusion coating method or the like.

IPC: C03B19/02
Filed: 1992-09-09
Abstract: PURPOSE:To obtain a definite high gain in broader wavelength area than that in the present circumstances by containing a specific amount of chlorine in a core part, in a optical wave guide of fluoride glass consisting of a ZBLAN- based fluoride glass and containing praseodymium (Pr) at least in the core part. CONSTITUTION:Fluorine as a constituent anion of a ZBLAN-based fluoride glass doped with Pr, concretely PrF is substituted with chlorine so as to contain 2-15mol% in a core part to prepare the objective optical wave guide. Thereby, wavelength area of signal light whose gain value is >=90% of the maximum gain value becomes broader than the wavelength range of 1300-1310mum in the present circumstances. For example, the ZBLAN-based fluoride glass containing Pr, concretely PrF3 and PbF2 is produced as follows. The chlorine concentration is controlled by substituting a part of BaF2 in the raw material with BaCl2. The substituted material is melted to prepare a rod for the core part. A pipe for clad is separately prepared by using ZBLAN-based fluoride glass doped with Hf, specifically HfF3 and the core part is inserted into the pipe for clad.

Title: Position detector
Inventor: OKUYA NORIO
IPC: G01D5/36
Filed: 1986-10-09
Abstract: PURPOSE:To obtain the title detector capable of being easily made large-scaled and made low in resolving power, by arranging the periodic slits on a slit plate so as to allow the same to cross the moving direction of the slit plate at a predetermined angle. CONSTITUTION:The light emitted from a light source 11 becomes parallel luminous flux by a collimator lens 12 to irradiate a moving slit plate 13. A large number of slits 18, 19 are respectively arranged on the slit plate 13 and a fixed slit plate 14 at an interval P at an angle theta with respect to the moving direction of the slit plate 13 so as to be symmetric in the direction crossing the moving direction. The light transmitting through the slits 18 irradiates the slit plate 13 and the light transmitting through the slits 19 irradiates a light detector 15. By this mechanism, the cycle T of the change in the quantity of light with the movement of the slit plate 13 becomes T=P/sintheta in the moving quantity of the slit plate 13 with respect to the interval P and, as the angle theta is made smaller, the cycle T becomes larger regardless of the slit interval P and the same effect as a large slit interval is obtained while the small slit interval is kept intact and, therefore, a position can be stably detected with high accuracy.
