Inventor: FUJINO SHINJI
IPC: B65H27/00
Filed: 1994-09-06
Abstract: PURPOSE: To enable the conveyance of a low tension member, by the inexpensive equipment, by externally installing an outer cylinder in free revolution, keeping a prescribed gap, for an inner cylinder fixed in a nonrevolutlon state having a plurality of through holes on the whole length and supplying fluid into a gap through the through holes from the inside space of the inner cylinder. CONSTITUTION: When air is supplied into an inside space 4 in the direction of arrow 21 from an air feeding device 17, air is discharged into the gap 22 between an inner cylinder 2 and an outer cylinder 19, passing through a through hole 6, and discharged from the passages 23 and 24 which are formed from both the end parts of the outer cylinder 19 and the pressure adjusting rings 11 and 12. A static pressure is generated in the gap 22, and the outer cylinder 19 is floated up and supported by this static pressure. Since air is discharged in each equal quantity from the passages 23 and 24, the outer cylinder 19 is floated up and supported from the inner cylinder 2 at the position where each interval from the passages 23 and 24 becomes equal.  Since the outer cylinder 19 is free of the resistance which obstructs revolution, stable transfer is secured free from the breakage of the low tension material such as a metal foil sheet and a film.

Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To read even a bar code of high density distant from a scanner by varying the oscillation speed of an oscillatory mirror and then setting a proper scanning speed corresponding to the distance between the read bar code and scanner. SOLUTION: A rotator 11 is composed partially of a permanent magnet and rotates with the magnetic field of a driving coil 10. A reflector is provided in front of the rotator 11. A frame 12 supports the rotator 11 rotatably. A spiral spring 13 has its one end fixed to the rotator 11 and the other end fixed to the frame 12. This spiral spring 13 allows the rotator 11 have a natural oscillation frequency in its rotating direction. Then a link driving shaft is moved along its axis and then a link arm can have its arm expanded and contracted around an axis of rotation. In this case, the moment of inertia of the rotator 1 is changed by an inertial moment varying part 14 and the arm of the link arm is put away from the axis of rotation to increase the moment of inertia. Consequently, the laser light scanning speed decreases.

Title: Distributor
Inventor: IDE SHINICHI
IPC: F25B41/00
Filed: 1989-08-18
Abstract: PURPOSE:To even out the distribution of refrigerant by forming a refrigerant distributor part into which an inflow pipe having a small orifice for ejecting refrigerant is fitted and by raising from said tubular part at each hole for attaching an outflow pipe a flange on the outer side of which the outflow pipe is fitted. CONSTITUTION:Refrigerant B consisting of a two-phase flow of gas B1 and B2 flows into a distributor 13 from an inflow pipe 16 through a small orifice 15. The throttling effect of the small orifice 15 causes the two-phase flow to form a jet in which the gas B1 and the liquid B2 are mixed. The refrigerant ejected impinges against a substantially hemispherical impingement wall 17 so that the gas and the liquid are mixed further to form their uniform mixture inside the distributor 13. The refrigerant B spreads radially along the substantially hemispherical impingement wall 17 and branches into outflow pipes 21 attached to a tubular part 18 and flows out. The inside of the distributor 13 is small in volume so that the possibility of the liquid or the gas staying stagnant in part inside the distributor 13 is reduced. A flange is raised from each hole 19 for attaching an outflow pipe and the outflow pipe 21 is fitted on the outer side of the flange so that refrigerant B branches out uniformly without obstruction when it flows out.

Abstract: PURPOSE:To perform size comparing with no error between complements of both inputs in terms of display by inputting the bits except the code bits of integers X and Y to either one of both inputs of the comparator with the bits except the code bits of integers Y and X inputted to the other input of the comparator respectively, and deciding the relation of size. CONSTITUTION:The complement of 2 is displayed and the difference is decided by comparison between two binary integers X and Y showing the positive and negative values with use of code bits. In this case, a code bit X15 of an integer X and the bits Y0 - Y14 except the code bits of an integer Y are inputted to either one of two inputs of a code non-integer comparating circuit 10 together with a code bit Y15 of an integer Y and bits X0 - X14 except the code bits of an integer X inputted to the other input of the comparator 10 respectively. Thus the difference of value is decided between both inputs. In such a constitution, the decision is reversed with MSB = 1 and a negative number, then it coincids with the accurate result of decision. As a result, the size comparison is accurately performed.
