IPC: G01N27/90
Filed: 1994-04-20
Abstract: PURPOSE:To provide an eddy current probe which can relatively enhance detection sensitivity for abnormalities such as detects existing in the back face section of an inspected metal. CONSTITUTION:A probe 10 has a detection coil 02 disposed close to the center at the inner side of an exciting coil 01. The position of the detection coil 02 is so adjusted that excellent detectability can be obtained. Both the exciting coil 01 and the detection coil 02 are connected to a flow detector via a connection cable 130. An electromagnetic field is generated by the exciting coil 01, and a magnetic field affected by eddy current within an inspected metal 110 is detected by the detection coil 02, so that voltage is thereby induced. The detection coil 02 is almost free from a magnetic field acting on the surface section of the inspected metal 110 out of magnetic fields generated by the exciting coil 01, but it is affected only by the change of a magnetic field acting on the back face section of the inspected metal 110. Therefore, a signal caused by abnormalities such as defects and the like existing in the back face section of the inspected metal, is thereby amplified respectively.

Title: Transistor amplifier circuit
Inventor: SEKI KUNIO
IPC: H03F1/42
Filed: 1978-07-07
Abstract: PURPOSE:To prevent malfunction at the time of an excessive input by extracting the output of a differential transistor amplifier from a current Miller circuit via a resistance. CONSTITUTION:Both PNP transistor Q1 and NPN transistor Q2, constituting the cascaded and modified differential transistor amplifier, are connected to Q3 and Q4 constituting the current Miller circuit via resistance R1. When input terminal IN is applied with a negative excessive input signal, resistance R1 limits an output current to the current Miller circuit, causing a voltage drop across resistance R1. The power voltage of the amplifier circuit can therefore be prevented from falling without lowering the emitter potentials of Q3 and Q4 and output transistor Q4 can also be prevented from being saturated; even at the time of an excessive input, the operations of driving transistors Q6 and Q7 can be held, so that malfunction can be prevented.

Abstract: PURPOSE:To prevent a parasitic MOS transistor from occurring without preventing high integration of a semiconductor device by forming a channel shielding wiring for applying voltage which does not form a channel in an opposite conductivity diffusion layer between the opposite conductivity type diffusion layer and the channel induction wiring. CONSTITUTION:In a lateral semiconductor device, one conductivity type diffusion layer 31 and an opposite conductivity diffusion layer 32 are formed along the surface of a substrate 33. Namely, a channel induction wiring 34 is formed on the opposite conductivity type diffusion layer 32 which is sandwiched by the conductive type diffusion layer 31 and a voltage allowing the channel of a parasitic MOS transistor to be generated at the opposite conductivity type diffusion layer 32 is applied to a channel induction wiring 34 when a voltage exceeding a certain amount is applied between the conductivity type diffusion layers 31. Then, a channel shielding wiring 35, where voltage for preventing the channel from being formed at the opposite conductivity type diffusion layer 32, is formed between the opposite conductivity type diffusion layer 32 and the channel induction wiring 34. Thus, it becomes possible to prevent the parasitic MOS transistor from occurring without interrupting high integration.

Filed: 1981-05-28
Abstract: PURPOSE:To obtain a focusing signal and a tracking signal by arranging two photodetecting elements at a center part and two larger photodetecting elements on both sides in front of or behind an imaging position, and then processing  their outputs by adding and subtraction. CONSTITUTION:A detector 8 consists of a couple of split detectors 8a and 8b having large photodetection surfaces on both sides, and a couple of split detectors 8c and 8d having small photodetection surfaces at the center part, and their boundary directions coincide with each other. In this case, the sum of outputs of the two center split detectors 8c and 8d is equal to that of the two both-side split detectors 8a and 8b at a focusing position. As a disck deviates from a focusing state and moves away from an objective lens, a light spot on the detector 8 becomes smaller, and as the disk comes closer and closer to the lens, the spot becomes larger and larger. Thus, the output difference VF is obtained correspondingly. The VT includes a track shift signal.

Filed: 1979-06-30
Abstract: PURPOSE: To realize the simultaneous writing of the data into two output/input devices without reading the data double out of the main unit but by installing plural units of interfaces plus the means which sets and stores the working mode.  
     CONSTITUTION: FF41, 42 and 43 indicate the double-write mode, the slave mode and the lock mode each. When module M1 is under the slave mode, M1 takes the data on bus 51 into data buffer 32 via multiplexer 31 and by data delay signal 53 sent from M2 in case FF43 is set. Then if data request signal 12 is given from the input/output device through interface 3, the head data of buffer 32 is put on bus 11. And signal 12 is sent to M2 in the form of signal 22. On the contrary, signal 52 is sent from M2 based on the data request signal sent from the input/output device which is connected to M2. And when both signals 12 and 52 are "ON", data delay signal 13 is sent to the input/output device. Then when signal 12 becomes "ON" again, the data on bus 11 is switched to repeat the same action.
