Abstract: PURPOSE:To enable surface wave flaw detection without using any couplant by providing a generating means for a DC magnetic field and a transmitting coil made of a zigzag conductive material and setting the transmitting coil opposite to the surface of an object to be put in an ultrasonic wave sound field. CONSTITUTION:When the transmitting coil 19 is energized by a pulse power source, alternate opposite-directional currents 23 are caused to flow to induce an eddy current 27 on the surface of an object 10 to be inspected.

Further, when a reflected wave is propagated and reaches the transmitting coil 19, a current is induced at the transmitting coil 19 according to the Fleming's right- hand rule. Thus, this transducer operates as a reversible ultrasonic wave transducer B with an electromagnetic force to perform the surface flaw detection without using any couplant.

Title: Testing method of three-phase common tank-type breaker
Inventor: IWAI HIROMI
IPC: G01R31/333
Filed: 1982-12-16
Abstract: PURPOSE:To perform economically a test, by allowing the magnitude and the phase of the current flowed to the breaking part of each phase of a sample breaker to coincide with those of an actual circuit, and applying voltages equivalent to those of the actual circuit between break contacts of the breaking part of each phase and between the breaking part and the ground. CONSTITUTION:By power-on, a three-phase current which passes through a current adjusting reactor 2 and has a prescribed magnitude is supplied to a sample breaker 4. Load-side terminals of respective phases of the breaker 4 are connected to one another, and the phase sequence of currents flowed to respective phases of the sample breaker is equal to that of the actual circuit, and this breaker is equivalent to the actual circuit completely with respect to current if the variable distortion of the current due to an arc voltage is not considered. Generally, it is unnecessary to compensate the variable distortion due to the arc voltage. Consequently, the intra-tank distribution state and the change with time of a high-temperature gas which is stored in a common tank and is discharged from the breaking part of each phase are equal to those of the actual circuit, and dielectric strengths between break contacts in breaking parts, between breaking parts, and between breaking parts and the ground are equal to those for breaking in the actual circuit. As the result, the test is performed economically.

Abstract: PURPOSE:To eliminate the unbalance by storing the 1st and 2nd transmission codes having the bipolar unbalancing in a memory having addresses 2N, 2N+1 with respect to an original code N, to output the above transmission codes stored in accordance with unbalancing. CONSTITUTION:The 1st transmission code in 6-bit having a positive unbalancing with respect to a code value N and a 3-bit weight code representing the unbalancing are stored in an address 2N of a code conversion memory 23, and the 2nd transmission code in 6-bit having a negative unbalancing and a 3-bit weight code representing the unbalancing are stored in the address 2N+1. An accumulator 25 accumulates the weight codes sequentially and outputs the LSB of the address depending on the result. Since the input code N is inputted to a high- order bit of the address, the code becomes a value 2N. Thus, a transmission code corresponding to the code N canceling the unbalance is outputted to an output register.

IPC: H01L21/205
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To suppress generation of a fine scratch and a defective part being generated at the top of an oxide plug due to chemical-mechanical polishing by depositing a spin-on glass layer on the chemically and mechanically polished oxide layer and etching back the spin-on glass layer and the oxide layer. SOLUTION: After a linear oxide layer 112 is formed on an exposed substrate surface in a trench, an oxide material is deposited into the trench and at the same time onto the substrate surface, thus forming an oxide layer. The oxide layer is partially eliminated by chemical-mechanical polishing, thus forming an oxide layer 118. Then, a thin spin-on glass layer 122 is deposited on the oxide layer 118, thus covering generated fine scratches and defective parts. Then, the spin-on glass layer 122 is etched back, thus exposing a silicon nitride layer 104, thus eliminating scratches and defective parts another generated on the surface of the oxide layer 118 and at the same time suppressing the another occurrence.

Title: Manufacture of semiconductor device
Inventor: AZUMA HIROYASU
IPC: H01L21/331
Filed: 1984-10-22
Abstract: PURPOSE:To reduce junction capacitance between an emitter and a base, and to improve performance by shortening a distance between an emitter region and a base region through self-alignment and surrounding the periphery of the emitter region by an insulating film. CONSTITUTION:A distance between an emitter region 112 and a polycrystalline silicon film 109 as a base-region extracting electrode is extremely small because it is determined in a self-alignment manner by the thickness of a silicon oxide film 106 and a silicon nitride film 107. Consequently, base resistance can be reduced excessively. Since the side surfaces of the emitter region 112 are coated with the silicon oxide film 106, an emitter-base junction is shaped only on the base of the emitter region, thus reducing junction capacitance, then also generat ing no concentration of an electric field. Accordingly, a bipolar transistor having high performance can be formed. The method can also be applied to a PNP type transistor by changing a conduction type.
