Title: Heat transfer pipe
Inventor: ITOU MASAAKI
IPC: F28F1/40
Filed: 1981-08-10
Abstract: PURPOSE: To increase the heat transfer efficiency of the heat transfer pipe and to reduce a pressure loss by a method wherein a spiral groove is formed on the wall of the heat transfer pipe and the depth, the pitch, the sectional configuration and the angle of inclination of the groove with respect to the axis of the pipe are specified.  
     CONSTITUTION: The spiral groove 2 is formed on the inner wall surface of the heat transfer pipe 1. In this case, the depth of the groove 2 is made to be of 0.02W 0.2mm, the pitch thereof to be of 0.1W0.5mm and the angle β of inclination thereof with respect to the axis of the pipe to be of 4W15°. Further, in case the groove 2 is V-shaped in configuration, the vertical angle is made smaller than an acute angle while in case it is U-shaped in configuration, the ratio of its length is larger than 0.4. Consequently, the transfer of a liquid in the groove is made easily due to the surface tension of the liquid which makes it possible to obtain a high heat transfer efficiency in cooperation with the effect of increasing the sectional area of the heat transfer surface. Further, as the liquid smoothes the groove by covering same, the pressure loss is reduced to the same level as in the case of the conventional smooth pipe.

Title: Method for estimating core position of multiple optical fiber and alignment method
Inventor: KUBO TOSHIKI
IPC: G02B6/40
Filed: 1996-04-22
Abstract: PROBLEM TO BE SOLVED: To deal with optical fibers having large eccentricity as well by integrally aligning the cores of the multiple optical fibers and aligning the central positions of the cores with images of a low magnification which allow the observation of the whole of the multiple optical fiber but do not allow the observation of the cores. SOLUTION: The eccentricity rates ΔL, ΔR between the left and right optical fibers are first determined by observing the fibers at the high magnification (a). Next, the magnification is changed over to the low magnification so that all the fibers can be simultaneously observed (b). The fibers are thereafter discretely so aligned that the misalignment of the center 100 between the outside diameters of the left and right fibers attains ΔL-ΔR with the left fiber as a reference. The relation between the left and right fibers is made like (d) although the fibers are actually invisible. The core positions are thus aligned.

Title: Freezer and method for adjusting its freezing capacity
Inventor: HIGO MORINAGA
IPC: F25B9/02
Filed: 1990-05-15
Abstract: PURPOSE:To get an efficient maximum freezing capacity of a freezer by a method wherein the freezer is provided with a suction pressure and a discharging pressure control means for a compressor for use in controlling an amount of refrigrant in a cycle and capable of changing a compressing level while a compression ratio of the refrigerant compressor installed in the cycle being kept constant or substantially constant. CONSTITUTION:When an expansion turbine inlet temperature is kept constant, an expansion turbine processing amount is proportional to an expansion turbine inlet pressure, i.e., a compressor discharging pressure and at the same time a compressor air volume is proportional to the suction pressure. Accordingly, if the compression ratio of compressor 2 is kept constant, it becomes possible to make the compressor processing air volume when the suction pressure is reduced coincide with the expansion turbine processing amount when the discharging pressure is reduced and thus it is also possible to get a compressor driving power and a cold in correspondence with the case in which a required freezing load is reduced under a normal operation. That is, when a pre-cooling operation is carried out, a valve 11a if herium gas feeding circuit 11 is opened, herium is fed from a tank 10 into a main circuit 9, a discharging pressure is increased and a pressure level in the main circuit 9 is increased. A cooling capacity in a freezer 1 is taken out in its maximum amount so as to shorten the pre-cooling time.
