Title: Automatic paper feeder for large sized shredder
Inventor: TAKANO KAZUHIKO
IPC: B65H5/02
Filed: 1993-10-20
Abstract: PURPOSE:To dispense with operation monitoring and the preset feeding work of paper waste by an operator by arranging a paper amount regulating sheet on the upper face of a conveying belt conveyor and reducing the volume of paper waste thrown in a heap to a proper amount by repeating advance and retraction of a feeding belt conveyor so as to make conveying of the paper waste possible. CONSTITUTION:When paper waste 20 to be disposed is thrown in a dust box 2 and the work is started, the paper waste 20 is fed from a discharging port with its heap gradually crumbled by advancing and retracting of a feeding belt conveyor 14. Then, the paper waste 20 collides against the lowermost line of a suspended paper amount regulating sheet 13, and a part. of it is nipped between the sheet 13 and a conveying belt conveyor 3, while most of the paper waste 20 is pushed backward. As the feeding belt conveyor 14 is retracted further, only a part of the paper waste 20 is loaded on the conveying belt conveyor 3 so as to be conveyed. The volume of the paper waste 20 is finally reduced to the height less than the height of a conveying projection 7 and is conveyed, and the paper waste 20 is peeled off by a guide plate 16, and then, thrown into a large size shredder.

Title: Drum type cloth drying machine
Inventor: SATOMURA MASAFUMI
IPC: D06F58/02
Filed: 1988-11-11
Abstract: PURPOSE:To eliminate the nonuniformity of drying and to shorten a drying time by forming plural baffle members, which fall down to the lower part of a drum after an object to be dried is hung up to a prescribed height, with being extended from one end face side of the drum to the other end face side and inclining the member by a specified angle. CONSTITUTION:On the inner curved surface of a ring-shaped drum 20, three baffles are fitted and in a part which is positioned in an exhausting port 25 side, a baffle 21 is inclined by an angle, with which a rotary phase is delayed toward the rotary direction of the drum 20, in comparison with a part to be positioned in a sending-in port 24 side. Then, a baffle 22 is inclined by an angle to advance the rotary phase. A baffle 23 is fitted parallelly with a rotary shaft 26 of the drum 20. An object 27 to be dried, which is hung up by the baffle 22, moves on the baffle 22 and falls down. Then, the object is directly brought into contact with hot air from the sending-in port 24. On the other hand, an object 28 to be dried, which is hung up by the baffle 21, moves on the baffle 21 toward the exhausting port 25 in an opposite side falls down. Then, the object 28 is not directly brought into contact with the hot air. Since the object to be dried is repeatedly moved between the sending-in port 24 side and exhausting port 25 side, the nonuniformity of the drying can be eliminated.

IPC: B22D41/18
Filed: 1993-11-16
Abstract: PURPOSE:To improve thermal conduction efficiency so as to suppress the formation of half-solidified matter and to prevent the leakage of molten metal from a sealing part by forming the front end of a metering valve rod to a hemispherical shape and providing a part right above this hemispherical shape part with a reduced diameter part. CONSTITUTION:A prescribed amt. of molten metal 15a is poured from a molten metal discharge port 65 into an injection sleeve 3 while the metering valve rod 26 is held risen. The metering valve rod 26 is lowered to close the valve after completion of the pouring. A valve seat part 81 and the hemispherical shape part of the metering valve rod 26 come into contact with each other and sealing is accomplished at a sealing surface 81a at the time of valve closing. The reduced diameter part 26b is disposed between the metering valve rod 26 and the hemispherical shape part 26a, by which the half solidified matter, oxides, etc., are hardly formed on the sealing surface 81a of the valve seat part 81 as there is sufficient replenisment of heat from the molten metal 15a even if heat is radiated from the lower side of the valve seat part 81. The perfect sealing is thus executed.

IPC: G01N33/483
Filed: 1987-11-13
Abstract: PURPOSE:To accurately control the tension of tissue by visually measuring the tension added to the tissue of a soft part to be sutured or transferred during operation, by mounting two switches changed over by the control signal from a microprocessor in order to take in the offset quantity of tissue by a change in tension or temp. CONSTITUTION:At first, a switch SW1 is turned ON and a switch SW2 is turned OFF and the bending quantity of tissue corresponding to tension is electrically detected by a resistance strain gauge 1 to calculate bending quantity V0i which is, in turn, inputted to a differential amplifier 4. Next, when the switch SW1 is turned OFF and the switch SW2 is turned ON, two signal voltages inputted to the differential amplifier 4 become the same potential and the output voltage from a sample holding circuit 7 must become zero but, when there is a temp. change, said voltage does not necessarily become zero by the effect of the characteristic of an element accompanied by said temp. change. Hereupon, said value is inputted as offset quantity v1i to finish one sampling. When sampling is finished several times, the offset quantity v1i corresponding to each bending quantity V0i is removed from said quantity V0i.

Abstract: PURPOSE:To widen a measurement range to enable calculation at normal speed by providing a first address generation circuit for reading the received signal of RAM by azimuth direction, a second address generation circuit read from ROM and a cumulative multiplier. CONSTITUTION:RAM 2 stores a detected signal by all azimuth directions. An address generation circuit 3 is written into RAM 2 to give a reading address. ROM 4 stores the weight for an input signal X(m,n). An address generation circuit 5 gives a reading address ROM 4. A cumulative multiplier 6 gives (multiply) weight from ROM 4 to the input X(m,n) given by a tri-state buffer 1 to cumulate them. A timing generation circuit 7 transmits timing signals to the tri-state buffer 1, RAM 2 and the multiplier 6 respectively. By the above constitution, since a quantity of calculation on the circumference finding movement average for the thinned circumference is distributed, the whole quantity of calculation does not change even if a measurement range is widened and it is possible to process it with the use of a circuit having the conventional calculation speed.
