Title: Unidirectional clutch
Inventor: NAGATANI SHUICHI
IPC: F16D41/07
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To eliminate locking failure by making tilting force to tilt sprags in a direction to bite into between inner and outer rings on a contact point with a guide surface of each of the sprags larger than friction force between the sprags working on the contact point and the guide surface. SOLUTION: A sprag 5 transmits torque by receiving pressing force F1 of a plate spring 6 and tilting in a direction to bite into between inner and outer rings 1, 2 at the time of increasing angular speed. At the time of reducing the angular speed, the sprag 5 tilts in a direction to slide on the inner and outer rings 1, 2, blocks torque transmission, the sprag 5 bites into between a guide surface 8 and the plate spring 6, and tilting in the biting direction is restrained by friction force F3 between the sprag 5 and the guide surface 8 working on a contact point Q with the guide surface 8 at the time of increasing the angular speed next time.  At this time, tilting force F2 in the tangential direction to tilt the sprag 5 in the biting direction by receiving the pressing force F1 on the contact point Q works, and it is larger than the friction force F3, and the sprag 5 can tilt in the biting direction between the inner and outer rings 1, 2. Consequently, it is possible to eliminate locking failure at the time of increasing the angular speed.

With regard to each of the X and the Y directions, increments DEX, DEY of a radial square error in the case a picture drawing point moves by a one-picture element portion are derived by a first means A. Subsequently, radial square errors e1 = e0 + DEX, e2 = e0 + DEY, and e3 = e0 + EDX + DEY of each point P1 - P3 are derived. In three adjacent points P1 - P3, the point whose absolute value is the smallest is derived by a second means B, and it becomes the next picture drawing point.

Title: Method for converting oxide into metal
Inventor: SASAHIRA AKIRA
IPC: G21C19/44
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To convert an oxide into a metal by performing cathode reduction with the oxide as a cathode in place of the reduction of an oxide by metal lithium. SOLUTION: Li2 O is added to molten salt by a charge machine 7. Voltage is applied to a carbon anode and basket by an electrolysis power source 8, while an anode rotation device 6 rotates a carbon anode. When voltage is applied so as to make the basket negative potential lower than the carbon anode, oxide acts as a cathode, and the oxide is converted into a metal by chemical reaction to produce Li2 O. Since the carbon anode is rotated by the anode rotation device 6, convection produces toward the carbon anode from the bottom center of an electrolytic cell, and produced Li2 O is carried to an anode. On the anode, Li2 O is decomposed by chemical reaction and concentration of Li2 O is held constant. Reduction reaction of PuO2 +C→Pu+CO2 is electro- chemically performed, and conversion to the metal of the oxide is performed.

Then the size of the shape memory alloy 2 is expanded by the body temperature, the polymer 3 is also expanded as time lapses, resulting that the polymer 1 is fitted closely to the ear. Thus, the leakage of sound is less and the signal is reproduced up to low frequencies.
