摘要： PURPOSE:To furnish a position adjusting device which is free from a positional displacement of a die due to a play of backlash or the like and enables the adjustment of the position of the die with a small force, by adjusting the position by means of an adjusting bolt on which a pressing force acts constantly. CONSTITUTION:In order to move a die 20 in the vertical direction, for instance, a fluid is removed from fluid rams 24A and 24C to move a position adjusting bolt 26A upward or downward. Thereafter the plunger 24a of the fluid ram 24A is pushed in a full stroke, and then a fluid is supplied to the fluid ram 24C to fix the die 20. A fluid pressure or the diameter of the rams is set to that thrusts PA and PC generated in the fluid rams 24A and 24C be PA>PC>P, wherein P is a force required for moving the die 20. The strokes of the fluid rams 24A and 24C are set to be larger than the strokes of position adjusting bolts 26A and 26C.

摘要： PURPOSE:To restrict a volume of nitride oxide generated by a method wherein a bypassing duct not passing in a heat exchanger device is arranged at least either one of the air duct or a discharged gas duct, and a change-over damper for controlling a volume of fluid is arranged in the duct. CONSTITUTION:A bypass duct 8 not passing in a heat exchanger 1 is arranged from a discharging gas duct 3a between the boiler 5 and the heat exchanger 1 to a discharging gas duct 3b between the boiler 5 and the chimney 7. Each of the change-over dampers 9a to 9c is fixed in each of said ducts 3a, 3b and 8. A degree of opening of each of the dampers 9a to 9c is adjusted in a range of operation of high load having a high fuel consumption of the boiler 5 in reference to a volume of nitride oxide in the chimney 7 measured by a concentrometer 10 for nitride oxide and a flow rate of fuel measured by a flow meter 11. Thereby, a volume of combustion air 17 applied for a heat exchanging in the heat exchanger 1 and a volume of discharged gas 16 are controlled, and a volume of the nitride oxide in the chimney 7 is restricted to a value lower than a desired value.

摘要： PURPOSE:To improve heat transmitting performance of a heat pipe, by ensuring adhesiveness of a wick by inserting into a heat pipe an inner pipe having a similar sectional configuration as a container and an outer diameter substantially equal to the inner diameter of the wick at the portion thereof where it is to be bent in bending a portion of the heat pipe having a wick fitted therein. CONSTITUTION:At a portion 1 of container 3 in the form of a straight pipe having a wick 2 fitted therein where it is to be bent, there is inserted a tubular member 5 which has an outer diameter substantially equal to the inner diameter of the wick 2 and a similar sectional configuration as the container 3. Then, the portion 1 of the straight pipe 3 where it is to be bent is bent into a required shape by means of a pipe bender. By thus manufacturing the heat pipe, it is enabled to ensure adhesiveness of the wick 2 to the inner wall surface of the container 3 and to prevent clogging of the pipe, so that heat transmitting performance of the heat pipe can be improved.

摘要： PURPOSE:To obtain a highly precise quantity of working liquid, prevent air penetration and make properties uniform by providing a valve at the top of an unfinished heat pipe, inserting the bottom into a working liquid inside a tank, replacing an air inside an unfinished pipe with a working liquid vapor from the valve and finally introducing the working liquid into the unfinished pipe. CONSTITUTION:A three-point valve 9 is provided at the top of an unfinished heat pipe 1 and the bottom is inserted into a working liquid inside a liquid tank 11 up to a position to meet a hermetically contained quantity. Then a working liquid vapor 5a is introduced into the unfinished pipe 1 from a channel 10a. Next, a tubular passage 10a is closed and a tubular passage 10a is opened to expose the unfinished pipe 1 to an atmosphere. Consequently the working liquid 5 inside a liquid tank 11 flows into the unfinished pipe 1, pushing up a working liquid 5a inside and discharging a vapor through a flow passage 10b. When a prearranged hermetically contained quantity is filled, a valve 9 is closed and the unfinished pipe 1 is pulled out of a liquid tank as it is. Following this procedure, the upper and lower ends are pressed, sealed and cut. In this manner, it is possible to obtain a highly precise quantity of hermetically contained working liquid, prevent air penetration and make properties uniform.

摘要： PURPOSE:To prevent the damage of the light emitting and receiving surface of a light emitting and receiving element by recessing the lens part (spherical projecting part) of a spherically pointed optical fiber to be optically coupled to this light emitting and receiving element from the connecting end face to the light emitting and receiving element. CONSTITUTION:A core part 1b at the end face 1a of the spherically pointed optical fiber 1 is formed as the spherical projecting part 2 projecting from the end face part 1c near this core part. The front end 2a of the spherical projecting part 2 is aligned to the light emitting surface 3a of a semiconductor laser (LD) 3. The end face part 1d at the outer peripheral edge exclusive of the end face 1c of the end face 1a and the end face part 3b exclusive of the light emitting surface 3 of the LD 3 are welded by using, for example, solder. The spherically pointed optical fiber 1 and the LD 3 are fixed to each other. The front end 2a of the spherical projecting part 2 is recessed from the end face part 1d at the outer peripheral edge in such a case. Then, the damage of the light emitting surface 3a by contacting of the front end 2a of the spherical projecting part 2 with the light emitting surface 3a of the LD 3 is prevented in the process of the operation to align the light emitting surface 3a and the spherical projecting part 2.
