Title: Higher harmonic overcurrent relay
Inventor: NAKAJIMA YASUO
IPC: G01R19/08
Filed: 1990-02-08
Abstract: PURPOSE:To simplify the circuitry by determining a ratio between a value obtained by converting the basic wave component extracted from a current to be detected into an average value with a value obtained by converting the higher harmonic component into an average value, and comparing thus determined ratio with a predetermined operation set value. CONSTITUTION:A basic wave component is extracted from a current to be detected, i.e., an input current 1, through a basic wave bandpass filter 16 and then the basic wave component is rectified and smoothed 17 thus determining an average value. The basic wave component is then subtracted 18 from the input current 1 to produce a higher harmonic component, which is then rectified and smoothed 19 thus determining an average value. The average value of the higher harmonic component is then divided by the average value of the basic component thus determining the ratio of the higher harmonic component. Thus determined ratio is then compared 6 with a reference value in an operation setter 5, and a comparator 6 produces an output when the reference value is exceeded. A time limit circuit 7 provides relay outputs 9, such as make/ breake operation of relay contacts at a predetermined time limit, based on outputs from the comparator 6 and a time limit setter 8. Consequently, it is not required to arrange a higher harmonic overcurrent relay for every capacitor bank.

Title: Paper-feeding mechanism
Inventor: YOSHIKAWA JIYUNICHI
IPC: B41J11/38
Filed: 1983-02-25
Abstract: PURPOSE:To remarkably simplify construction and markedly reduce structural hunting at fitting parts, by a method wherein displacements due to ON/OFF operations are absorbed by utilizing a minutely stretchable and contractable property of a belt form body. CONSTITUTION:When a platen knob 7 is pushed in the direction of an arrow 19, a projected part 7-a thereof moves an outer transmitting member 11 in the direction of the arrow 19 against a spring 18, thereby releasing the engagement of tooth parts 11-b, 16-a of a clutch, resulting in an OFF condition wherein no torque is transmitted. In this case, a timing belt 10 is diaplaced following up to the member 11, resulting in a stretched condition. On the other hand, an increase in the length of the belt is extremely minute, and the belt is elastic, so that no trouble is generated. In this condition, a paper is fed by a minute amount by rotating the platen knob 7 by a minute amount. This is effected by transmitting a torque to an inner transmitting member 16 by a rotation stopper 7-c of the platen knob 7 and rotating a platen shaft 2-a.

Abstract: PURPOSE:To raise the probability of attainment of a well-focused photograph by designating a specified limited distance range on the occasion that any ripple caused by an illuminating light source is contained in a reflected light even when no reflected light is detected by a distance-measuring element. CONSTITUTION:When the ripple of the reflected light is detected through the intermediary of a photodiode 9 and a root-point detecting circuit 53 during a prescribed period when a switch 51 is closed at the 2nd pressing stage of a shutter SB and the output of a monostable multivibrator 52 turns to be at a low level, the output of FF55 is reversed to be at a high level, whereby reading of memory circuits 21-24 corresponding to photodiodes 5-8 for measuring light and distance is conducted. And, when none of diodes 5-8 detect the reflected light, an AND gate 27 is opened through the intermediary of an exclusive OR gate 26 and a compensating distance signal given by the diode 9 through the intermediary of a memory circuit 25 is given to a decoder 30. Then, in the case when no reflected light is detected by the distance-measuring element and a ripple light is detected, the distance is determined not to be infinite remoteness but to be in the specified distance, and thus the probability of attainment of the well-focused photograph can be raised.

Title: Fault detecting device for solar battery
Inventor: SAKATA SUEO
IPC: H01L31/04
Filed: 1982-02-26
Abstract: PURPOSE:To obtain the fault detecting device for the solar batteries, which can detect faulty position quickly, by grounding a neutal point of a generating block, and detecting the current flowing between the neutral point and the ground. CONSTITUTION:Eo is a voltage across each block. The voltages of solar battery panels 1 are synthesized on both sides of the neutral points X other than a block A1, and the voltage of Eo/2 is obtained. The neutral point x is grounded through a resistance Z=gamma/(m-1), with the internal impedance of a relay being neglected. When the fault is not present, the potential of the neutral point X1 of the block A1 is also Eo/2, and a current does not flow through a relay 9. When a short- circuit occurs at a point Y between the solar battery panels P1 and P2, a closed loop is formed through the shorted point Y, the panel P2... the neutal point X1,  a resistor 8, and the relay 9. The current IR flowing the relay 9 is shown by the expression in the Figure. When a short circuit occurs at a point separated by one panel from X1, the current becomes IR=Eo/n.gamma. The relay 9 is made to be operated at this value.
