Filed: 1988-04-27
Abstract: PURPOSE:To reduce the rotating vibration of a motor by opening a hole at front and rear side plates, and using them bearings for supporting the rotation and thrust of the output shaft of the motor. CONSTITUTION:A stepping motor has a motor output shaft 21, a front side plate 22 and a rear side plate 26, and also outer and inner yokes 23, 24. The yokes 23, 24 are formed in a predetermined toothform and set to a predetermined number of teeth to match the stepping angles, opposed at a predetermined angle, and the conductions of coils 25, 25a are sequentially switched by a step signal to rotate a rotor. In this case, bearings 22a, 26a of the shaft 21 are provided by means such as barring at the centers of the plates 22, 26. Thus, since the centering of the shaft 21 is determined only by the assembling accuracy of the plates 22, 26 and the hole inner diameter, its centering is facilitated.

Abstract: PURPOSE:To obtain stable substrate potential without consuming unnecessary currents by controlling charging and discharging capability by a MOSFET at output nodes for NOT circuits at each step of a ring oscillator by an oscillation frequency control circuit on the basis of an output signal from a substrate-potential detecting circuit. CONSTITUTION:NOT circuits by MOSFETs 115, 116 are connected in parallel with NOT circuits 113 at several step of a ring oscillator 101, and currents flowing through the MOSFETs 115, 116 are limited by gates 114, 117. A signal 107 is connected to the gate 114 and the NOT signal 108 of the signal 107 to the gate 117.

When the potential of the substrate 106 is lowered, on the contrary, the signal 107 is at low potential and the signal 108 is at high potential, currents flowing through the gates 114, 117 are limited, the oscillation frequency of the oscillator 101 is lowered, and potential generated in the circuit 102 is elevated.

Title: Rotary tiller
Inventor: TAKEUCHI MASASHI
IPC: A01B33/10
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To prevent the winding of grasses on tilling tines and tilling shafts, and at the same time, to solve troubles caused by collisions of tilling tines against obstacles buried in soil. SOLUTION: Each set of a normally rotating tilling shaft 34 and oppositely rotating tilling shaft 46 extends in the left or the right direction from a mission case 13. On each set of shafts, tilling tines 49a to 49f are placed, and also disk shaped dividing boards 50a to 50c are placed in such a manner that they touch the front ends of the tilling tines 49a to 49f. Due to the dividing boards 50a to 50c, the winding of grasses on the tilling tines and the tilling shafts can be prevented, and at the same time, when the dividing boards 50a to 50c touch obstacles such as stones or wood pieces buried in soil, the machine body is pushed up to result in the prevention of the collision of tilling tines 49a to 49f against such obstacles.  This can prevent the trouble of giving foreign feeling to the operator attributable to the sudden changes of the driving force or resisting force of the machine body caused by the reaction of the rotating tilling tines 49a to 49f received from the obstacles.

IPC: G03G21/00
Filed: 1980-08-01
Abstract: PURPOSE:To prevent sticking of toner without reducing a cleaning capability by regulating a quantity and a polarity of electricity charging on a cleaning brush. CONSTITUTION:For example, a lower side cleaning brush 4 is charged with electricity of positive polarity through a conductive member 8c which is provided in one side of an insulating member 8a of a center flicker bar 8, then toner stuck on a photosensitive drum 1 is sucked electrostatically, and, at the same time, is made to cleaning by napping 4a. Since repulsive actions among remained toners are generated by an upper cleaning brush 4 charged with electricity through a conductive member 8b of the bar 8 applied high DC voltage of negative polarity, the remained toner is cleaned well by the same way as above. The removed toner from the drum is conveyed without sticking and piling at any part by electrostatic oscillation of sheets 6a, 7a of electrostatic curtains, which are prepared on the inner surfaces of an  upper-and a lower housing 6, 7, and by a blowing action of the brushes 4. Further,  the brushes destaticized through the sheets 6a, 7a are charged with electricity again  by the flicker bar 8.

IPC: H04N1/028
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To prevent lowering in the output level of a photoelectric transform signal ant at the same time to increase the reading speed by controlling the quantity of irradiated light in response to the set resolution of a sensor unit containing a photoelectric transducer which can perform the switching between the 1st and 2nd resolution levels via a resolution switching means. SOLUTION: The photodetectors a1-d1 carry out the photoelectric transform via the photodiodes Pd-a to Pd-d and generate the optical carriers. These optical carriers transform the electric charge into the voltage via the MOS source followers M3a-M3d and transfers the voltage to the storage capacitors Ca-Cd by a signal transfer pulse ϕT and with coincidence of all pixels. Then the read pulses ϕa1-ϕd1 which are sequentially set at high levels are read in sequence out of a shift register 11 and the read switches M1a-M1d are turned on. Then the signal voltage is read out to a common communication line 14 as the division of capacity. In a high resolution mode, the pulses ϕa1-ϕd1 are sequentially turned on, and the adjacent two bits are simultaneously turned on in a low resolution mode.
