Filed: 1980-05-06
Abstract: PURPOSE: To raise the junction with soil of a three dimensional network structure to be used for strengthening the slope or in the drainage by forming large numbers  of synthetic polymer filaments having a specific diameter into an irregularly looped and netted mat shape.  
     CONSTITUTION: A netted mat is constructed by a method in which synthetic polymer filaments having a diameter of 0.1W1.5m/m are each crossed with one another into irregular loops 3, the structure 1 thus obtained is stretched from its one end to the other end while bending it in the thickwise direction, and then intersections 4 are bonded at each point. On the surface of the structure 1, large numbers of furrows 6 and ridges 5 bending and stretching in almost right-angle direction are formed. These furrows 6 and the ridges 5 are formed into ridges 5' and furrows 6' when turned inside out, and the ridges 5 on the surface appear to be stepped form from above. Thus, when the structure 1 is laid on the slope, and frictional couplement between the structure 1 and soil is made better and the slope can therefore be strengthened.

Title: Rotation detecting method and apparatus
Inventor: KOBAYASHI SHINYA
IPC: H02P3/08
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To surely detect stop of rotation by detecting a rotation signal of which level changes depending on rotation to judge rotation is stopped when the level of the rotation signal does not change for the predetermined period. SOLUTION: When a rotation detection gear 3 rotates due to rotation of a motor 2, a microswitch 4 repeats ON/OFF conditions by means of a rotation detecting gear 3. The microswitch 4 generates a pule signal which becomes low and high levels to supply this signal to a motor controller 5. When the predetermined period has passed after an output level does not change, a drive mechanism 9 is fixed and thereby the rotation detecting gear 3 does not rotate and thereby the motor 2 can be judged in the locked condition. Therefore, the motor is judged in the locked condition. Since stop of rotation of motor is judged when the level of the rotation signal does not change for the predetermined period, stop of rotation can surely be detected.

Abstract: PURPOSE:To improve a storage device of floating gate structure in reliability, where a silicon nitride tunneling insulating film is used, by a method wherein an acid resistant mask layer is locally formed only on a part that serves as a tunneling region of the surface of a diffusion layer. CONSTITUTION:N-type diffusion layers 2, 3, and 4 are formed on a P-type silicon substrate 1, and then a thin silicon oxide film 12 and a thin silicon nitride film 13 are successively formed thereon. Then, an etching process is carried out so as to leave the silicon nitride film 13 and the silicon oxide film 12 unremoved only on a part which is to serve as a tunneling region above the N-type diffusion layer. An oxidation process is executed to form a thick silicon oxide film 14 on a part other than the tunneling region. In the oxidation process, the upper part of the silicon nitride film 13 is oxidized to a some extent and a thin silicon oxide film 15 is formed. A process follows, where a floating gate electrode 8 and a selection gate electrode 9 are formed of a polysilicon film doped with phosphorus at the same time. In succession, silicon oxide film 10 is formed on the electrode 8. Then, a control gate electrode 11 is formed of a polysilicon film doped with phosphorus, and thus a semiconductor storage device of floating gate type is realized.
