Inventor: MORIOKA HIROSHI
IPC: E04B1/34
Filed: 1988-07-22
Abstract: PURPOSE:To improve earthquake-proof characteristics of a building, by arranging outer steel center pillars facing to inner steel corner pillars in a super- multistoried building which has double-tube structure, and connecting the pillars together by trusses each of which has one story-height on every several stories.

Title: Brake controller of automatic door
Inventor: GOSHIMA TERUO
IPC: E05F15/00
Filed: 1984-08-31
Abstract: PURPOSE:To smoothly maintain a door operation by selecting the amplitude of a control force of brake means from next on the basis of the number of pulse signals corresponding to the braking distance of a door when the door is stopped. CONSTITUTION:A door 2 is closed at relatively low speed to a complete closure. The number of counts of a counter 9 corresponds to the zone distance for closing at relatively low speed, and corresponds indirectly to the braking distance. A computer 10 selects a duty ratio from next on the basis of the counted value of the counter 9 obtained during closing operation at relatively low speed. Accordingly, if the counted value is large, the duty ratio becomes small. Thus, a brake force is weakened, and next braking effect decreases. Thus, since the brake force corresponding to the weight of the door 2 is corrected, the braking distance is eventually substantially constant irrespective of the weight of the door 2.

Title: Printing head
Inventor: YONEDA EISAKU
IPC: B41J2/235
Filed: 1984-08-31
Abstract: PURPOSE:To provide abrasion resistance, enable noises to be absorbed and suppress attenuation of a magnetic force, by a construction wherein a vibration- damping alloy is provided between parts where mechanical contact of an electromagnet and an armature occurs, and an armature chamber is filled with a magnetic fluid. CONSTITUTION:When the armature 9 is returned from a released condition to an attracted condition, it strongly collides against an attracting surface of an iron core 6, so that the attracting surface is abraded and noise is generated. To avoid this, the vibration-damping alloy 15 consisting of a sintered non- magnetic 25Cr-20Ni austenitic steel material is fixed to the attracting surface so that it is intermediately located between the armature 9 and the attracting surface of the iron core 6. The alloy 15, because of its high damping capacity, reduces vibration and noise. In addition, the armature chamber 17 is filled with a magnetic fluid 18, whereby the magnetic force of the core 6 can be exerted on the armature 9 (with the alloy 15 therebetween) through the magnetic fluid 18. Accordingly, attenuation of the magnetic force on the armature 9 can be prevented, and a sound-deafening effect can be also expected.
