Abstract: An alloy-coated boiler part is furnished with a melted coating of alloy material excellent in erosion/corrosion resistance when joined by welding, and free from thermal shock cracking. Super alloy coating (15) is applied over rapid temperature rise region width (C), where thermal shock cracking may occur at a welding operation, at end portions subjected to weld joint including the vicinity. Self-fluxing alloy coating (16) is applied on remaining regions other than the rapid temperature rise region width (C). While over a half proportion of each of the alloy coatings (15, 16) occupied by an Ni-enriched Ni—Cr component, the super alloy coating (15) has the contents of B and Si suppressed to equal or less than 0.1% and equal or less than 0.5%, respectively, and in the self-fluxing alloy coating (16), the content of each of B and Si is in the range of 1 to 5%.

Abstract: A pulse tube refrigerator that is small in size and free from vibration and electric noise. A pulse tube refrigerator (1) has a pulse tube, a cool storage unit connected to the low-temperature side of the pulse tube, a vibration generator connected to the high-temperature side of the cool storage unit, and a reservoir with an orifice, connected to the high-temperature side of the pulse tube. The vibration generator is a thermally driven pressure wave generator having thermal drive tubes (heat exchangers (4-4a) for heat radiation), a phase shifter (7), and a return path (6). Sufficiently heating a heat exchanger (3) for heating causes self-exciting vibration to be generated in a work transmission tube (5), and work is returned to the thermal drive tubes through the phase shifter (7) and the return path (6) arranged on the work output side of the work transmission tube (5).

Abstract: In the pressure oscillation generator 1, self-excited vibration is generated in a work transfer tube 30 by heating a heat input section 22 and also a resonator 50 is resonated, and when a work is inputted into a heat exchanger 20, the work is amplified by the heat exchanger 20, and is transferred to the heat transfer tube 30 and is then outputted to an output section 40. Because of the configuration, an outputted work can be amplified to a work larger than the inputted work, so that, by using a portion of the outputted work as energy for driving the cylinder 10, the pressure oscillation generator 1 can continuously be driven only by heating and without using electric energy generated by a large scale solar system or the like, which enables substantial size reduction of the pressure oscillation generator 1.

The beam receiving section is formed by a device, such as a semiconductor position sensitive detector, which is capable of producing an output which varies according to a reflected beam brightness and reflected beam receiving position (which reflects the height level of the reflection surface). On the basis of the output of the beam receiving section, reflected beam brightness information and height level information at respective positions on the inspection surface are prepared. From the reflected beam brightness information at the respective positions, an existing region of each of the lands on the inspection surface can be fixed.

Abstract: A method of applying a film, preferably of PET, to a surface, preferably the front surface of the panel of a CRT. Resin is first applied to the surface in a predetermined pattern. The film is then pressed against a part of the surface near one edge of it by a roller. The roller is then moved across the surface to press the film onto the resin. The pressure exerted by the roller is reduced in the middle of the surface as compared with that exerted at the edge. Two different pressures may be used in the middle part.
