Patent JP-S4719353-A (JP)
IPC: H02H3/093
Filed: 1971-02-18
Abstract: An overcurrent protective circuit or means comprising static solid state non-linear elements connected in parallel with an input signal conditioning means such that an overload current in a protected circuit is sensed by the input signal conditioning means and then converted into a signal which is applied simultaneously to each of the non-linear elements. An output current which is directly proportional to or varies with the value of overcurrent in the protected circuit is generated by each non-linear element after the overload current exceeds predetermined values which may be different for the respective non-linear elements. The output from each of the non-linear elements, is supplied to a corresponding associated modulating means such as an oscillator, multivibrator or current generator. These modulating means combine to generate a current signal that is proportional to the overload current in the protected circuit raised to some power N where N is related to the number of modulating means. This current is then applied to charge a capacitor which effectively integrates the current with respect to time. Integration converts the charging current into a voltage signal which is directly proportional to the Nth power of the overload current in the protected circuit. The voltage signal is then compared with a reference or threshold voltage in a trigger circuit and when it exceeds the reference voltage, a signal is generated by the trigger circuit which actuates a circuit breaker tripping means causing the circuit breaker protecting the aforementioned circuit to open or trip.

Title: Detection of broken bulb filament
Inventor: MATSUI HIDEJI
IPC: H01K3/00
Filed: 1990-01-25
Abstract: PURPOSE:To detect a broken filament in either case that a bulb is on or off by discriminating a voltage across a detecting resistance by means of a comparator through a current flowing the detecting resistance when the bulb is on and detecting the broken filament through voltage detection when the bulb is off. CONSTITUTION:For example, when flicker signals are input to the gate G of a field effect transistor(FET) 3 so that the input of the FET 3 is at an H level, the FET 3 is ON to light on a bulb 1 and if the bulb 1 is in a normal condition the drain D-side point A of the FET 3 is at a L level and the output terminal B of a comparator 4 is at an H level, and when the gate G of the FET 3 is at a L level the FET 3 is OFF to light off the bulb 1 but the drain D-side point A of the FET 3 is at an H level, so that output signals are obtained in both cases. When the broken filament of the bulb 1 occurs, both of the drain D-side point A of the FET 3 and the output-side point B of the comparator 4 are at an L level regardless of the condition of the FET 3, so that output signals are not obtained in both cases. It is thus possible to detect the broken filament in either case that the bulb is on or off.

Title: Bilateral t gate
Inventor: YAMAKAWA RETSU
IPC: H03K17/693
Filed: 1985-01-30
Abstract: PURPOSE:To attain the bilateral flow of the voltage of current signals by having comparison the currents delivered from plural current sources and a selection circuit respectively and delivering a control signal which turns on one of plural switches in response to the result of said comparison. CONSTITUTION:A current mirror 31 is turned on when a current I1 larger than a current I2, while a current mirror 32 produces a sucking output current I2. Therefore the voltage of a high level is impressed to the gate of an N-MOS FET forming a floating switch 1F. Thus this FET is turned on and therefore the current J of a current source 2 is detected through a terminal 4 in the form of the output voltage I0. When the current I1 is smaller than the current I2, the mirror 32 is turned on. While the mirror 31 produces a discharge output current I1. Thus the FET of the switch 1F is kept off and the output current I0 is equal to 0. As a result, a T gate has the bilateral properties and its field of applications is increased.

Abstract: PURPOSE:To obtain a horizontal resistor with a good transmission efficiency without reducing a storage capacity too much even in the case of a small amount of transmission charge, by additionally implanting an n-type impurity into the whole area in the horizontal transmission direction and into a part of the area in a direction perpendicular to the horizontal transmission direction. CONSTITUTION:First, an n-type impurity is implanted into a p-type semiconductor substrate 11 to form a channel area. Then, an n-type impurity is additionally implanted into the whole area in the horizontal transmission direction and part of the area in a direction perpendicular to the horizontal transmission direction, where a first layer polysilicon 12 is sticked. After self-alignment of this polysilicon layer, an additional n-type impurity is implanted, where the second layer polysilicon 13 is sticked. Now, an n13' and n<+>14 areas exist under the polysilicon 12, and an n<+>15 and n<++>16 areas exist under the polysilicon 13. By this, a transmission charge is stored to be transmitted afterward in the area 14 under the polysilicon 12 and the area 16 under the polysilicon 13 when the amount of a transmission charge is small. Since an additional n-type impurity is implanted only into a part of the area, a storage capacity is not reduced so much.

Abstract: PURPOSE:To grind a work with a prescribed working precision independently of the abrasion of a plug gauge by installing a work dimension measuring device for measuring the dimension of a work after working and a working time adjusting means and continuing the working during the calculated time after the plug gauge is inserted into the next work. CONSTITUTION:After the inner surface of a work 2 is ground to the dimension of a plug gauge 1, and said gauge 1 is fitted into the work 2, the work 2 is delivered. The inside diameter of the work 2 is measured by a working dimension measuring device 3, and the abrasion quantity of the plug gauge 1 is input into a working time adjusting means 4. When the plug gauge 1 is worn out and the above-described measurement value becomes less than a prescribed dimension, the additional working time after the gauge 1 is fitted into the work 2 is calculated and memorized by the working time adjusting means 4. In the grinding for the next work, the adjusting means 4 instructs the additional work for the calculated working time after the gauge 1 is fitted into the work. Therefore, the grinding shortage due to the abrasion of the plug gauge 1 is corrected.
