Title: Breaker of permanent current in superconducting loop
Inventor: FUJIMAKI NORIO
IPC: G11C11/44
Filed: 1989-01-24
Abstract: PURPOSE:To enable the permanent current generated by the interlinkage of outer flux with a loop to be broken by a method wherein the down time constant in pulse current wave form is made smaller than the thermal time constant of the system comprising a resistor and the superconducting loop. CONSTITUTION:A resistor 22 is arranged near the part 21a of a superconducting loop 21 and then the resistor 22 is fed with a pulse current Itau from a power supply 23 through a wire 24. The down time constant tauE of the current Itau is made sufficiently smaller than the thermal time constant tauT of the system comprising the part 21a of the loop 21 and the resistor 22. Therefore, when the resistor 22 is fed with the current 14, the loop 21 is kept in the superconductive state so long as the temperature T of the loop 21 is raised not to exceed the superconduction transition point Tc but the superconductive state is ended to break the loop current IL as soon as T exceeds Tc. Consequently, any needless permanent current due to trap flux etc., can be broken without fail.

Title: Noise-reducing device for business apparatus
Inventor: YAMAGUCHI MICHIMASA
IPC: B41J29/08
Filed: 1984-02-02
Abstract: PURPOSE:To contrive reduction in noise and a smaller device, by a construction wherein an inlet to a bent passage of an interference-type soundproofing device is opened in an outlet passage so that a portion of the noise passing through the outlet passage is passed through the bent passage, whereby a direct propagating sound and a refracted propagating sound are made to interfere with each other. CONSTITUTION:The noise emitted through a printing paper outlet 4 is divided into the direct propagating sound A passing through the outlet passage 8 and the refracted propagating sound B passing through the bent passage 10 of the interference-type soundproofing device 6. In this case, since the refracted propagating sound B passes through the bent passage 10 having a length different from the length of the outlet passage 8, the phase of the sound B is shifted from the phase of the direct propagating sound A. Due to the phase shift, the sound A and the sound B interfere with each other, forming an interference sound-reducing region C. Accordingly, the noise emitted through the paper outlet 4 of the printer can be reduced.
