Title: System for searching fault point of optical fiber transmission line
Inventor: ASAHARA TADASHI
IPC: G01M11/00
Filed: 1979-04-13
Abstract: PURPOSE:To search the fault point of a transmission line which cannot be detected by the reflected light of a reflector provided at one end of the optical fiber transmission line by reciprocating a light pulse in the transmission line by the reflector and searching the point by the number of pulse at the time when the number of pulses of both ends of the transmission line is stopped counting. CONSTITUTION:An input pulse signal P1 becomes a light pulse signal moving rightwardly by a light transmitter 1, and transmitted through a directional coupler 2 to an optical fiber transmission line 3. This pulse signal is partially passed through a reflector 4 into a light receiver 5, which produces a pulse signal P2, and partially reflected by the reflector 4 to move leftwardly into a light receiver 6, which produces a pulse signal P3. The signals P3, P2 are counted in number of pulse by counters 7, 8, respectively. Assuming that the pulse repetition period of the pulse signal P1 is represented by T, the speed of the light pulse signal in the transmission line 3 is by V, a fault occurs at time t at the point X of the transmission line 3 and the counters 7, 8 stop counting at the counted values N1, N2, respectively, the distance l can be obtained by the difference N1-N2 of the counted values by the formula (1).

CONSTITUTION:A high density polyethylene layer with 0.94-0.97g/cm<3> density and 0.02-2g/10min melt index (MI) and a low density polyethylene layer with 0.915-0.934g/cm<3> density and 0.5-5.5g/10min MI are laminated in (0.5-7):1 ratio by thickness to form a packing film. At this time, to one or both of the layers is added a transmission preventive absorbing light of >=100mmu. A dark pigment such as carbon black and benzotriazole as a near ultraviolet absorber are combinedly used as the preventive. Thus, packing causing no trouble is enabled by means of an automatic packing machine.

Abstract: PROBLEM TO BE SOLVED: To simply center an inner peripheral blade by stretching the inner peripheral blade on a tension head by prescribed tension, and shaving off it by abutting a dressing stone to an eccentric part of its edge while rotating the inner peripheral blade. SOLUTION: An inner peripheral blade 18 to cut an ingot is installed on a tension head 20 of a work cutting part. At this time, the inner peripheral blade 18 is stretched out with a high tension by outer peripheral directional tension of a press ring 22 of the tension head 20. When the inner peripheral blade 18 is to be centered, the tension head 20 on which the inner peripheral blade 18 is installed is rotated by a spindle 28, and a dressing device 34 is driven. A fairing groove 40a of a dressing stone 40 is opposed to an edge 18a of the rotating inner peripheral blade 18. Next, this fairing groove 40a is abutted to the edge 18a of the inner peripheral blade by a horizontal slider 48, and is dressed. In this way, the inner peripheral blade can be efficiently centered.

Title: Paper feeding system for printer
Inventor: ARAGAKI TAKAHIKO
IPC: B41J11/26
Filed: 1985-03-07
Abstract: PURPOSE:To lengthen the service life of a platen by making the turning speed of the platen slower than the peripheral speed of a tractor. CONSTITUTION:In a paper feeding system for a printer, in which a platen 4 and a tractor 3 are driven by a paper feeding motor, the turning speed of the platen is made slower than the peripheral speed of the tractor. The inertial load JL in terms of motor shaft is represented by the formula (I), where Z1 is the number of teeth of the platen gear 1, Z2 is the number of teeth of the motor gear 2, JM is the rotor inertia of the motor, and JP is inertia of the platen. If the peripheral speed of the platen 4 is 1/4 of the feeding speed of paper, the teeth number Z1 becomes 4 times greater than the teeth number Z1' of the platen gear 1'. Therefore, the inertial ratio in terms of the motor shaft of the platen 4 is represented by the formula (2), or reduced to 1/16. The inertial load by motor shaft conversion can thus be reduced, and the service life of the platen can be lengthened.

Title: Pneumatic hammering device
Inventor: MIURA TADAHIKO
IPC: E02D7/10
Filed: 1980-04-09
Abstract: PURPOSE: To perform pile driving utilizing full energy employed, eliminating pile damaging and  reducing hammering noise by a method wherein the timing for feed and stop-feed of high pressure  gas is regulated and the use of expanding power is fully displayed.   
     CONSTITUTION: When a switch is ON, the high pressure gas enters at first into the intake tube 7a  then to the loop space 16 that is provided at the bottom of a cylinder 1' through the feeder tube 8,  pushing up the weight 3' further to the level where the intake port 7 is opened then enters to the  cylinder 1' through the tube 7. When the ram 3' is pushed up further, the circuit switch S 1  and S 2   are closed and consequently the control valve 2' is closed and the supply of high pressure gas is  suspended. The remaining high pressure gas in the cylinder 1', while expanding, pushes up the  weight 3' further to the level where the intake-exhaust hole 10 is opened, then fed to the intake  hole of the compressor P through the hole 10 while the gas is in its finish expansion stage. The gas pressure finally reaches below the atmospheric pressure inducing the open air into the cylinder,  causing the weight 3' to fall under its own weight. The gas within the cylinder 1' is compressed to  some extent being induced into the compressor P through the intake-exhaust port 10 and after the  weight 3' falls the port 10 is closed, causing the air in the cylinder 1' to be compressed again,  thereby reducing the falling speed of the weight 3'.
