Title: Foreign matter collision diagnosis device for rotary machine
Inventor: YANAGIBASHI MINORU
IPC: G01H17/00
Filed: 1986-04-11
Abstract: PURPOSE:To immediately diagnose a foreign matter collision by detecting a collision sound by an acoustic sensor provided to a baring part and processing its output signal. CONSTITUTION:The output of the acoustic sensor 1 is amplified 2 and detected 3. When a small foreign grain strikes on a rotary blade, an acoustic signal due to the collision is generated, a mean value circuit 4 converts the output of an amplifying circuit 2 into a mean value, and a V/F converter 5 outputs pulses proportional to a voltage value; and a counter 6a outputs a DC voltage proportional to counted values and a standard device 7a outputs a signal for operating an alarm 10a when the output of the counter 6a exceeds a standard value. Then if a large foreign grain strikes, an impulsive waveform is generated, detected 3, and compared 8 with a threshold voltage, and a signal exceeding a voltage E is converted into a pulse signal as the output of the comparator 8, thereby outputting a signal for operating an alarm 10c through a counter 6b and a standard device 7b. The outputs of small-grain and large- grain collision detecting circuits 20 and 30 are inputted to a small- and large-grain simultaneous generating and detecting circuit 40 and an alarm is generated 10b when the AND result is satisfied.

Inventor: SASAMOTO TAKAO
IPC: B65B7/14
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To stably fix a tube-fixing shaft onto a tube-fixing base and facilitate the detachment of the tube-fixing shaft as well. SOLUTION: This tube-fixing shaft 63 comprises a first fittable shaft 85, a fittable groove 87, and a second fittable shaft 89, and a tube-fixing hole 59 comprises a first fittable hole 69, a projection 73, and a second fittable hole 75. A gap between the second fittable shaft and second fittable hole after fitting is smaller than a gap between the first fittable shaft and first fittable hole after fitting. By fitting the fittable groove 87 and projection 73 together, and also fitting the second fittable shaft 89 and second fittable hole 75 together, the tube-fixing shaft 63 can surely be fixed to a tube-fixing base 59. Additionally, because the inside diameter of the first fittable hole 69 is larger than the outside diameter of the second fittable shaft 89, the detachment of the tube-fixing shaft 63 from the tube-fixing base 59 can be made easy.

Abstract: PURPOSE:To safely produce the low-loss optical coupler by selecting the heating temp. and heating time of the plural optical fibers to substantially expand the core diameter of the respective optical fibers in the case of welding the side faces of the optical fibers to each other and stretching the same. CONSTITUTION:The heating temp. and heating time are so selected that dopants are diffused by the heating and the outside diameter of the cores 11 of the optical fibers 101 to 103 is substantially expanded in the case of aligning the axial directions of the plural optical fibers 101 to 103, disposing the side faces thereof so as to circumscribe each other, heating the side faces thereof to fuse the side faces to each other, stretching the fibers. Namely, the fibers are so heated that the dopants previously compounded for the purpose of a refractive index adjustment are diffused into one of the cores 11 or clads 12 or into each other, by which the core diameter is substantially increased and the thickness of the clads 12 is reduced. The thickness of the clad layers 12 existing between the respective optical fibers 101 to 103 is reduced after the welding and stretching without executing the treatment to previously remove the clads 12 by chemicals, etc. The loss of light signals is thus lowered.

Title: Regenerative capsule
Inventor: YAMAGUCHI TOSHIHIRO
IPC: F28D20/00
Filed: 1983-05-12
Abstract: PURPOSE:To prevent regenerative material from being over-cooled, by providing an element made of shape memory alloy, which is transformed at the solidifying point of regenerative material or at the temperature slightly lower than that point when the temperature in the material is decreasing, and is returned to the initial shape at the temperature higher than the solidifying point when the temperature is increasing, in the regenerative material. CONSTITUTION:When a regenerative capsule 1 is cooled down and the temperature is lowered down to the solidifying point or the temperature slightly lower than that point, a stirring element 5 is transformed to produce what is like a swirl flow in a regenerative material 4, so that the regenerative material 4 starts solidifying and is turned into a solid as shown in the figure tau3. The shape transformable temperature of shape memory alloy is higher (t2'>t1') when it is increasing, than the case when it is decreasing, so that the alloy is transformed after the regenerative material 4 is completely liquefied when the material is melted. Further effect can be expected if the capsule is composed of an element 5 supported by a support rod 6 as shown in the figure 1'.

Filed: 1979-07-03
Abstract: PURPOSE: To make possible the automatic reversion of the ordinary ink ribbon by reversing the ribbon by a spring force at the final end thereof after the stoppage of the ribbon feed drive source at the ink ribbon feeder of the impact type printer.  
     CONSTITUTION: As the ink ribbon 1 being delivered from the right ribbon spool approaches its end, the eyelet for detecting the end is sent out. The eyelet catches the bar 6b at the tip of the ribbon end detecting lever 4b and turns it counterclockwise. Consequently, the detention lever 7 shifts to the right so that the post 7b is positioned at the right of the post 10a. The drive gear 17 is halted and as the bias force of the detention spring 13 exceeds the friction force in the meshing of the gears, the gear meshing control lever 10 turns counterclockwise causing the crown gears 15b to be meshed with the driven gear 19b thereby inverting the ribbon feeding.
