Inventor: MIYAZAKI KENICHI
IPC: E04B1/342
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To variably change three-dimensional shape of a structure by vertically jointing layers constituted of a plurality of modules through a slide mechanism, and installing a propulsion mechanism whose respective modules displace in the horizontal direction. SOLUTION: This shape-variable structure by contour module integration is provided with a plurality of vertical layers constituted of a plurality of modules 1 on the same plane, and the modules 1, 1 of the vertical layers are jointed to each other vertically with a slide mechanism 2. The respective modules 1 are provided with a propulsion mechanism 3 which moves in the horizontal direction at every module layer. When the propulsion mechanism 3 is driven, only the module 1 of one layer moves inwards and outwards in the radial direction, independent of the vertical layers, in a jointed condition to the nearest upper and lower modules and in a closed-curve arrangement condition. In such a movement of the module 1, all modules on the same horizontal plane move uniformly at only one layer, so that its closed curve expands or contracts.  It is thus possible to three-dimentionally deform the whole structure in various patterns.

Title: Paper sheet stacker
Inventor: ARIGA TOSHIO
IPC: B65H29/40
Filed: 1985-09-30
Abstract: PURPOSE:To stack paper sheets always with the end faces of them being aligned with each other by forming the wedge-like terminal end side of a blade groove. CONSTITUTION:When the transferred leading ends of paper sheets P entering blade grooves 18 with high speed reach intersection portions 41 of blade 17 and a disk 40, said ends bite like a wedge into the intersection portion 41 and the surplus energy will be consumed to deform the paper sheet P in the blade groove 18. When said end abuts against a guide member 30 as the impellers 15, 15 are rotated, the impellers 15, 15 keep rotating while the transfer of the paper sheets P is impeded so that the paper sheets P are removed from the blade grooves 18 to be eventually dropped and stacked on a receiving-stacking plate 32. Here, since said end is held by the intersection portion 41 right before it reaches the guide member 30 it is not repelled when it collides with the guide member 30, so that the paper sheets can be dropped along the guide member 30.

Title: Line driver circuit
Inventor: IIZUKA EIJI
IPC: H03K19/0175
Filed: 1988-08-31
Abstract: PURPOSE:To match an output impedance to the characteristic impedance of a transmission cable by executing the complementary turning-on/off operation of two switching elements for the generation of a pulse signal. CONSTITUTION:Switching elements 10 and 12 execute the complementary turning-on/off operation and a current flows through the switching element, which is in a turning-on condition, a pulse transformer 14 and a resistor 16. The pulse signal of an amplitude Vcc/n is generated in the secondary side of the pulse transformer 14 and sent to the transmission cable. When the transmission cable is released, the output impedance of a line driver circuit, which is matched to the characteristic impedance of the transmission cable, becomes infinite and the current does not flow to the pulse transformer 14. A voltage in the intermediate tap of the primary side coil of the pulse transformer 14 tries to be boosted up to the level of a power source voltage Vcc, however, the voltage in the intermediate tap is clamped by a Zener voltage since there is a Zener diode 18.
