Title: Discharged paper sheet stacker for image forming device
Inventor: KATO YASUO
IPC: B65H31/24
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To smoothly perform paper discharge operation and accurate image forming by drawing out only the stacker on the last stage and preventing paper sheets to collide against a stopper on the stacker in regard to an image forming device having movable stackers for stacking and storing paper sheets discharged from an image forming device body composed of a plurality of members and having them slide between the storage position where the stackers are laid on the top of another and the position from where they are drawn out in consecutive order. SOLUTION: With a first and a second movable stackers 72, 78 stored under a device body, the second movable stacker 78 only can not be drawn out because a protrusion 78a of the second movable stacker 78 fits into the lock 76b of a lever member 76. The lever member 76 may face a cutout 75a by, first, pulling out the first movable stacker 72 from the device body along a rail member 75.

IPC: G06F17/16
Filed: 1989-06-09
Abstract: PURPOSE:To omit a multiplication part for reduction of the cost of a vector arithmetic unit by using a multiplication part and a pair of addition/subtraction parts where the output of one of these two parts can be selected as the input of the other and connecting the multiplication part directly to one of both addition/subtraction parts when a composite arithmetic is requested to the addition/subtraction after multiplication with the other addition/subtraction part set opposite to another addition/subtraction request. CONSTITUTION:The parallel processes are carried out with high efficiency and a small hardware quantity among the multiplication operations, the multiplication and addition/subtraction composite arithmetic operations, and the addition/subtraction operations by noting a fact that the number of continuous multiplication instructions is small and the number of continuous composite arithmetic instructions of multiplication and addition/subtraction and addition/ subtraction instructions is large respectively. That is, a multiplexer 4 selects the multiplication result A*B or an input C and adds it to one of both inputs of a 1st addition/subtraction part ADD-1. Meanwhile a multiplexer 5 selects the result A*B or an input E and adds it to one of both inputs of a 2nd addition part ADD-2. At the part ADD-1 the addition/subtraction is carried out between the multiplexer 4 and an input D and the result of this arithmetic is added to one of both inputs of a multiplexer 6. In the same way, the addition/subtraction is carried out between the output of the multiplexer 5 and an input F at the 2nd part ADD-2 respectively.

IPC: G01N35/00
Filed: 1981-09-18
Abstract: PURPOSE:To improve the safeness of operation of the titled device by fitting a slip clatch between a driving motor for respective driving sources of XY axis driving mechanism and a force transmitting sprocket. CONSTITUTION:The rotational shaft of a driving motor 1 drives a gear box 3 and an encoder/tachometer 2 simultaneously to control the moving distance and moving speed in the X and Y axial directions. A block OP injects reagents or subjects and detects optical responses from their products. After the speed of the motor 1 has been reduced down to a prescribed rotational ratio by the gear box 3, the sprocket 4 is rotated by the motor 1. If a malfunction or unnatural force is generated, the rotation of the motor 1 is separated from that of the sprocket 4 by a slip clatch 5 as a buffer mechanism and the motor 1 is stopped. When the sprocket 4 is rotated, two belts 7 are driven through the rotation of the driving shaft 8 of the Y axis and a belt 6 is directly driven. The movement of the belts 7 is interlocked with a Y moving stage 11' and the belt 6 with an optical injecting mechanism.

IPC: H03F1/02
Filed: 1978-11-25
Abstract: PURPOSE:To lessen the power loss of the amplifier circuit by providing the AC stable power source which is controlled by the output signal or the signal in which the negative feedback signal is piled on the DC signal and then driving the power amplifier circuit with the output of the power source. CONSTITUTION:The voltage conversion is given to the AC power source via transformer 2, and the AC power source is converted into the plus and minus DC voltage via rectifier circuit 101. Then power amplifier circuit 102 is driven via AC stable power circuit 103. Reference voltage supply terminals 12a and 12b of circuit 103 receive supply of the output signal of circuit 102 or the signal in which the negative feedback signal is piled on the DC voltage, and thus the output of circuit 102 is controlled. The fluctuation of the power voltage and the dispersion of the winding ratio of transformer 2 are absorbed by circuit 103 to supply the fixed voltage to circuit 102 at all times. As a result, the power loss can be reduced at circuit 102, which results in reduction of the thermal feedback from the final-step power part of the power amplifier circuit to the first-step amplification part. Thus a power amplifying IC is obtained with a high fidelity of the signal amplification.

Abstract: PURPOSE:To easily detect a position of a mobile station by providing an output of distance information from a stationary station to a mobile station and posi tion information of the mobile station comprising information of the directivity of an antenna. CONSTITUTION:A mobile station 7 detects a reply signal when a call signal from a base station is directed to the mobile station 7. A radio base station 1 uses a beam control section 2 to control a beam control antenna 5 thereby directing the beam in a direction in which a signal from the mobile station 7 is received with highest strength and fixing. In this state, the radio base station 1 emits a radio wave to the mobile station 7. Upon the receipt of a radio wave from the radio base station 1, the mobile station 7 emits a radio wave to the radio base station 1 after the lapse of a prescribed time (A). Then the radio base station 1 uses a communication range measurement section 3 to obtain a delay time based on a time when the radio base station 1 emits a radio wave and an arrival time of a reply signal from the mobile station 7 and calculate a half of a value subtracting processing time (A) from the time and the distance (L) up to the mobile station 7 is calculated from the value and the luminous flux.
