Title: Protective relay
Inventor: YAMAZAKI SHUJI
IPC: H02H3/32
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To perform analog input monitoring and power system protection, even if faults occur by providing input converting means which are connected to current-quantity taking-in means, and an analog input monitoring means which determines whether the values of analog current quantities detected by the input converting means or rations of the quantities of the analog currents are a specified value. SOLUTION: In an input converting means 2 of a digital relay 1 which is a protective relay, input converters are connected in parallel to the secondary circuit of a current transformer. Analog current quantities of a power system are inputted to the input converter means 2 having input converters connected in parallel. If the secondary current ratio of the current transformer is represented as K=I2/I1 at normal operation, |I1-KI1|=0 is satisfied, and analog input monitoring determines it as being 'normal'. If currents become unbalanced by a fault such as breaking of wire, etc., and if |I1-KI1|>=α, analog input monitoring detects malfunctioning.  Consequently, it is possible to perform analog input monitoring and power system protection, and to make a high reliability protective relay, even when a fault occurs in the secondary circuit of the current transformer.

IPC: H01L21/331
Filed: 1989-03-17
Abstract: PURPOSE:To realize a high speed transistor having a small effective element area, a short base running distance of carrier, small parasitic capacity between a base and a collector and a small base outer resistance by interposing an insulating layer between a first semiconductor and an electrode lead of second semiconductor. CONSTITUTION:An insulating layer 104 is interposed between a collector 101 and a base lead (an inverted L-shaped horizontal part), thereby largely reducing a parasitic capacity formed by the collector and the base lead. An effective element area is provided by the product tXl of a film thickness (t) and the width l of an element. Since an emitter 103 is formed of a thin film, an effective element area can be reduced by decreasing the thickness (t). As an alternative, an emitter 101 and a collector 103 may be formed instead.

Abstract: PURPOSE: To detect the punch hole accurately, by splitting the photo detector, excluding the field of detection receiving the leakage light flux due to meandering through the reception of output signal of the photo detector and the detector for the end, and selecting other detection field as an effective one.  
     CONSTITUTION: When a detected objective 3 is in meandering, a photo detector 2A receives the radiated light flux from a projector 1. Further, a photo detector 20A to detect the end of the detected object 3 also receives the radiated light flux from the projector 10A, the output of a logical product element 6A is at logical 0, and it is detected that the photo detector 2A receives the light flux leaked with meandering and no mis-output is produced. On the other hand, the photo detector 2B receives the radiated light flux from the projector 1 by punched holes 4. Further, since the photo detector 20B does not receive the radiated light flux of the projector 10B, an output is produced from a logical sum element 7. Accordingly, the punched holes 4 of the detected object 3 can accurately be detected.
