Title: Magnetic bubble element
Inventor: HIROSHIMA MINORU
IPC: G11C19/08
Filed: 1978-09-06
Abstract: PURPOSE: To widen the margin of a bias magnetic field by stabilizing operation characteristics of a transfer line by providing a transfer-line element, having a function of elongating bubbles in a bubble transfer direction, to a boundary moving to a part where there is no conductor pattern.  
     CONSTITUTION: Transfer-line element 11 where magnetic bubble Bubl is expanded when passing in magnetic-bubble transfer direction P through step Dout at a boundary moving from a part with conductor loop 2 to a part without it. Element 11 is widened in area to increase in volume, preferably in a width direction perpendicular to a transfer direction. For the purpose, height (h) of element 11 should be greater than height (h') of normal transfer-line element 10. As a result, when the transfer-line element is positioned at step part Dout, the margin of the bias magnetic field is prevented from lessening and the transfer operation is also prevented from becoming unstable easily.

IPC: H05B3/10
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To efficiently and uniformly heat up the whole of a heating roller to the surface temperature of the heating roller obtained when warming-up is finished by one heating lamp having such wattage that it can be actuated even by an inexpensive and compact power source by turning off a heating means for a prescribed period and moving the heat of the high temperature part of the heating roller to the low temperature part. SOLUTION: The heating roller 9 consists of a supporting part and a driving part so that it can be rotated at a fixed position. The heater lamp 10 inserted in the roller 9 is fixed by the supporting part. Then, when power is supplied by a power supply part, the lamp 10 is turned on to heat the roller 9. Before the surface temperature of the roller 9 arrives at the prescribed temperature, the lamp 10 is turned off for the prescribed period and the heat of the high temperature part of the roller 9 is moved to the low temperature part. This means, the surface temperature of the central part of of the roller 9 is lowered but those of the end parts of the roller 9 are raised while the lamp 10 is turned off. Thus, the temperature distribution of the roller 9 in the shaft direction can be nearly uniformized.

Title: Brake device in tape recorder
Inventor: SAWADA TAKASHI
IPC: G11B15/665
Filed: 1989-04-28
Abstract: PURPOSE:To stabilize brake torque against a reel base by forming a brake surface of a brake arm into a curved surface protruding to the side of abutting on a braked surface of the reel base. CONSTITUTION:When the reel base 4 is slightly smaller than designed dimensions, a contact point between a brake pad (brake surface) 23 and the braked surface 4c which does not follow the brake arm 21 in its clockwise turn is shifted out. Now, since this surface-contact state is the curved surface, they are kept in an approximately uniform state. Consequently, even when variations exist between the brake surface 23 of the brake arm 21 and the braked surface 4c of the reel base 4, the contact state between the brake surface 23 and the braked surface 4c of the reel base can be made approximately constant.
