Title: Decoder circuit
Inventor: HIGUCHI HIROSHI
IPC: G11C11/413
Filed: 1989-04-26
Abstract: PURPOSE:To shorten the delay time in decoders and to improve the address access speed by installing at least more than two predecoder circuits to which the same input signals are inputted in common, connecting plural logic circuits to subsequent stages and divisionally driving the circuits in the subsequent stages. CONSTITUTION:The common address signals from an address buffer, a1 and a2, for example, are inputted to respective predecoders PDC1-PDCn having the same constitution by the elements of the same size. Then, (m) decoders DEC1l- DEC1m-DECnl-DECnm of the same constitution are respectively connected to the subsequent stages of respective predecoders PDC1-PDCn. The output signals of DEC1l-DECnm are supplied to a load driver and a column switch. Thus, the input capacity of the decoders in the subsequent stages goes to 1/n, and the length of wiring connecting the predecoders and the decoders in the subsequent stages become short. Then, wiring resistances and wiring capacity become small and the delay time of the decoders is shortened.

Title: Medium feed roller mechanism
Inventor: INOUE HIROYUKI
IPC: B41J13/076
Filed: 1983-06-10
Abstract: PURPOSE:To keep off a lag for delivery of an original in time of starting as well as to prevent the original from overrunning in time of stoppage, by install ing a tubular member being longer than the circumferential length of a driven roller, in the outside of this driven roller, while specifying each friction factor in both its inner and outer circumferential surfaces. CONSTITUTION:In case of a medium feed mechanism consisting of a driven roller 200 opposed via a driving roller 100 and a medium 10, a tubular member 300 whose inner circumferential length is longer than outer circumferential length of the roller 200 is installed in the outside of the roller 200. When a friction factor lying between the outer circumferential surface of this member 300 and the surface of the medium 10 is set down to mu1 while another friction factor lying between the inner circumerential surface of the member 300 and the roller 200 to mu2, it is made so as to keep their relations as in an expression mu1>mu2, while an outer surface of the member 300 corresponding to a position where the roller 200 comes into contact with an inner surface of the member 300 is also made contact with the roller 100. With this constitution, since substantial turning moment in the driven roller is able to be made smaller, a lag for delivery of an original in time of starting as well as overrunning in the original in time of stoppage both can be prevented from occurring.

Filed: 1984-05-23
Abstract: PURPOSE:To prevent to the utmost the titled appliance from vibrating by a structure wherein an opening eccentric to the appliance plug side is provided on a heat shielding plate opposing to a fan motor. CONSTITUTION:An opening 13 is provided on a heat shielding plate 6 so as to be opposing to a fan motor 9.

IPC: G01G3/02
Filed: 1986-05-07
Abstract: PURPOSE:To obtain an indication without a shift error even though a plurality of load cells or levers are not used by providing displacement quantity detecting means for measuring the displacement of a specific point on a platform and equidistant from three or more supports. CONSTITUTION:A platform 1 is supported by compression springs 21-24 at four corners. These springs have the same elastic characteristics and spaces between the adjacent springs are equal to one another. A specific point 3 on the reverse side of the platform 1, said point 3 being equidistant from the the springs 21-24, moves in accordance with an applied load. When a load N is applied to the center of the platform 1, the quarter of the load N is applied to each of the springs 21-24, which is compressed by a distance P and the platform 1 moves. When the load N is applied to a position above a middle point between the springs 21 and 24, the half of the load N is applied to each of the springs 21 and 24 to compress it by 2P and no load is applied to the springs 22 and 23, so that the compression displacements thereof are zero and a space Q between the point 3 and a fixed side does not change. Accordingly, by determining weighed value information by measuring the displacement of the point 3, an indication without a shift error can be obtained.

Abstract: PURPOSE:To air-condition effectively a room utilizing geothermal heat, by positioning under a floor plate a container whose upper opening is covered with the floor plate and whose sides and bottom are insulated and which is filled with a heat accumulating material, and circulating a fluid through the container and a pile body buried in the ground. CONSTITUTION:When air is forced into the pile body 2 by a fan F, the air flows down an outer stream passage A2 around a conduit member 12 so that the heat of the air is exhanged with the heat of the ground which will be on the order of about 15 deg.C, then rises in an inner stream passage A1 in the conduit member 12, and is discharged via a discharge pipe 15 from outlets 13 into the container 5. Then after the heat of the air is exchanged with the heat of the heat accumulating material 4, the air is circulated via suction inlets 16 and a suction pipe 17 to the pile body 2. Thus the temperature in the container is kept approximately at the same as in the ground. Consequently, since, in winter, the heat accumulating material 4 is kept at relatively high temperatures, while, in summer, it is kept at low temperatures, heating and cooling can be effected through the floor plate 3. Thus, air-conditioning can be effectively realized using the heat in the ground.
