IPC: H01L21/822
Filed: 1984-03-23
Abstract: PURPOSE:To contrive reduction in element area by a method wherein the gate part of a controlling transistor is buried in a substrate without increasing the element area. CONSTITUTION:The part where an N type Si layer 2, a P type Si substrate 1 and a P type Si layer 5 are overlapped constitutes a capacitor to be used for accumulation of electricity. As this capacitor is increased in size in proportion to the area indicated by the product of the circumferential length of a pole-formed part and the height of the overlapped layers 2 and 5 and the sum of the cross-sectional area of the pole-formed part, a sufficient accumulation capacitance can be obtained by increasing the height of the overlapped layers 2 and 5 even when the area of the layer 2 is reduced. Also, a P type layer 3 constitutes the channel part of a controlling transistor (TR), and an N type Si layer 7 is used as a gate electrode and it is buried in an insulator 6 through the intermediary of a thin insulating layer in such a manner that the layer 7 will be overlapped on the P type layer 3 of the pole-formed region and the N type layers 2 and 4 located on both sides of the layer 3. The layers 2 and 4 correspond to the drain and source electrodes of the TR. If the standard of design is set at F, 2FX3F which is 6F in other words is obtained in the highest density state, thereby enabling to make the element area smaller in size, if the above-mentioned structure is used.

Filed: 1987-03-13
Abstract: PURPOSE:To automatically stop the shifting of a processing part immediately after completion of the processing so as to improve the work efficiency by placing a clutch, which operates by the load generated against the shifting by thread pitches at the collision of the processing part and the stopper, in a rotor forming thread pitches. CONSTITUTION:The processing part 6 is shifted in the axis center direction by pressing a nut 7 by a bolt 8 with the driving of a motor so as to perform bevel processing to a pipe 13 with a bite 13 at the processing part 6. When this processing part 6 has shifted to the specified position, the processing pert 6 collides against a stopper 15 and a large load is generated to the shifting by thread pitches. By this load, a ball clutch 9 placed between the bolt 8 and a sprocket gear 10 operates, whereby the connection between this bolt 8 and the sprocket gear 10 is released. As a result, even if a disc 5 is rotated further by the motor 2, this torque is not transmitted to the bolt 8 and the bolt 8 ceases to press the nut 7 and the shift of the processing part by thread pitches stops and the bevel processing for the pipe 13 ceases to advance.

Title: Electromagnetic acoustic transoucer
Inventor: MORIMOTO KAZUO
IPC: G01N29/04
Filed: 1982-04-06
Abstract: PURPOSE:To enable the generation of an SH wave efficiently over the entire circumferential wall of a thin tube without rotating the thin tube etc. by generating the ultrasonic wave (SH wave) simultaneously over the entire circumferential wall of the capillary. CONSTITUTION:An electromagnetic acoustic transducer EMAT11 is first disposed in the prescribed region in a thin tube 4. When high frequency current J is flowed to a coil 14 in this state, eddy current I in parallel with the axial direction of the tube is generated in the wall part of the thin tube 4. The magnetic flux B in parallel with the radial direction of the thin tube 4 is generated in the wall part of the thin tube 4 by the other core 12 and a permanent magnet 13, and Lorentz force F is generated. The SH wave is generated in the axial direction in the wall part of the thin tube 4 by the force F and eventually the SH wave is generated in the entire circumferential wall of the thin tube 4. The SH wave reflects a defective part or the like and returns to the transducer. The wave is converted to an electric signal, whereby the flaw detection of the thin tube 4 is made possible. The SH wave is thus generated efficiently in the entire circumferential wall of the thin tube without rotating the thin tube, etc. by the above-mentioned method.
