Title: Ribbon cartridge
Inventor: OKAMOTO ARATA
IPC: B41J32/02
Filed: 1979-11-08
Abstract: PURPOSE: To stabilize tensile force of the exposed portion of the ribbon drawn out of a cartridge by applying to the exposed portion of the ribbon drawn out of a cartridge a tensile force due to the difference between the circumferential speeds of the storing roller and the supplying roller when printing.  
     CONSTITUTION: A drive roller shaft 37 in a cartridge 20 is rotated at a given speed by a driving shaft 46 in a ribbon-driving unit 43. The rotation of the drive roller 37 is transmitted to a driven roller shaft 49 by a belt 42. Thus, a ribbon 28 is drawn out of a main storage chamber 22 by a drive roller 33, and fed into the main storage chamber 22 by a driven roller 35. Because the circumferential speeds of the drive roller 33 and the driven roller 35 are set so that the latter is higher than the former, the ribbon 28 travels with its exposed portion 28A kept tense between a pair of guide members 24 and 25.

Title: Superconductive induction motor
Inventor: IMAI ISATO
IPC: H02K17/02
Filed: 1987-06-12
Abstract: PURPOSE:To obtain an induction motor of high efficiency, by using a temperature characteristic of a superconductive material, in which starting is performed in a normal conducting state to suppress the starting current, and by lowering the temperature of a conductor in high speed to bring it into superconducting state. CONSTITUTION:A stator winding 2, a rotor end ring 4 and a bar 5 of a squirrel cage induction motor are made of a superconductive material. In starting the motor, it is in the normal conducting region. When the starting is finished and after it comes into a steady state, the stator winding 2, rotor end ring 4 and bar 5 are cooled so that it becomes superconducting state. As a result, as the primary and the secondary resistance will be zero ohm, the primary and secondary copper loss will be zero watt and the efficiency is improved. In starting the motor, since the starting is performed in the normal conducting state, no remarkable difference is found in the conventional induction motor and the starting current. Any one of the conductors among the stator winding 2, the end ring 4 and the bar 5 can be made of the superconductive material.

Title: Automatic control circuit of electrolytic protection
Inventor: YAMAGUCHI SUSUMU
IPC: C23F13/00
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To safely and surely execute electrolytic protection for a long period of time by switching to a circuit which directly inputs a protective potential to a comparison terminal of a comparator or inputs the same to the comparison terminal of the comparator by switching of a timer relay, in switching of protective energization to a protective electrode by a relay controller. SOLUTION: A timer 4 repetitively operates a timer relay 5 by a duty ratio of a long time and a short time, executes the protective energization at the time of the long time, stops the energization at the time of the short time, measures the protective potential and executes potential comparison. If the protective potential is higher than a reference potential 31 at the time of the protective potential comparison, the control relay 7 operates to stop the energization and, thereafter, even if the switching contact of the timer relay 5 changes over to the protective energization side, the comparison of the protective potential is continued and the protective energization is not executed.  When, however, the protective potential falls below the reference potential 31 before the next protective potential comparison by the timer relay 5, the comparator 1 reacts immediately and activates the control relay 7, thereby starting the protective energization.

Wire electrodes 5, as anode, provided at the top end of the nozzle 4 and the frame 3 as cathode are then energized. The current density is increased in the central part of the frame 3 where the two wire electrodes 5 are not shielded by the smallest diameter part 7; therefore, the plating thickness increases in said part. The current density decreases in the outside peripheral part of the frame 3 where one of the electrodes 5 is shielded by the smallest diameter part 7, and therefore, the plating thickness decreases.

Filed: 1990-06-04
Abstract: PURPOSE:To prevent the material fatigue of a hung spring by detecting the non- equilibratory weight on the hung spring, so as to compensate the non-euqilibrium of the hung length of each hung spring. CONSTITUTION:When the hung length of a hung spring 11 by a winder 12 is in a non-equilibratory state, and when the hung length of the hung spring 11 connected with an equilibrium maintaining means 15 is shorter than the other hung springs 11, an overload is given to the hung spring 11, and a rotor 18 that winds in the hung spring 11 wound by the spring force of a spring 19 of the equilibrium maintaining means 15, is rotated against the spring force, and the hung spring 11 is unwound thereby, and the hung length of the hung spring 11 becomes thus longer. When the hung length of the hung spring 11 connected with the equilibrium maintaining means 15 is longer than the other hung springs 11, the load given to the hung spring 11 is reduced, and the rotor 18 is rotated by the spring force of the equilibrium maintaining means 15, and the hung spring 11 is wound by the spring force, and the hung length of the hung spring 11 thus becomes shorter. The elevated body is thus maintained in a horiozontal state, and an overload is not given to the hung spring 11 for a long period of time, and the generation of the material fatigue of the hung spring 11 is thus prevented.
