Title: Non-volatile semiconductor memory cell
Inventor: MORI YASUHIRO
IPC: H01L21/8247
Filed: 1993-01-12
Abstract: PURPOSE:To accelerate the writing rate by a method wherein the floating gate of a non-volatile semiconductor cell is composed of multiple layers including single phase of high melting point metallic layer or the high melting point metallic layer itself. CONSTITUTION:After the formation of element separating regions 3 on a P type silicon substrate 17 a gate oxide film 2 is formed. Next, an Mo layer 4a is formed on the gate oxide film 2. The Mo layer 4a formed at this time becomes one layer of a floating gate to form a polysilicon layer 4b thereon to become another layer of the floating gate. The floating gate 4 is composed of these Mo layer 4a and polysilicon layer 4b. Through these procedures, a stress is easily imposed on the gate oxide film 2 beneath the Mo layer 4a so that the threshold voltage Vth shifting rate may be accelerated thereby enabling the writing rare to be accelerated.

Abstract: PURPOSE:To prevent the sagging down of a surface copper layer at the cutting part of a dumet wire when it is welded, in the slug lead which is formed by welding one end part of the dumet wire and one end part of a lead wire, by performing an area decreasing machining of the dumet wire at a specifiedd rate or less before the welding. CONSTITUTION:In order to obtain one raw material having a diameter of D= 0.8mm., which constitutes the slug lead A, the raw dumet wire of 0.8-0.84mm.phi is used. The surface reducing machining of 10% or less is performed by a low angle die whose angle is 2 deg.-6 deg.. In order to obtain the slug lead A, the dumet wire 1, whose surface reducting has finished, is cut as a stud. Even though the dumet wire 1 is welded to the lead wire 2, since the surface copper layer of the dumet wire is hardened by the surface reducing machining, a cut diameter ratio alpha/D becomes 99% or more, and the slant of a semiconductor element 3 and the cracks of sealing glass due to the sagging down of the cut part can be prevented.

Title: Device for identifying broadcasting signals
Inventor: YAMADA YOSHINOBU
IPC: H04N5/44
Filed: 1984-01-12
Abstract: PURPOSE:To identify a broadcasting signal by returning a high binary output to a low binary output and by returning a high binary output to a low one, when that the signals are not being inputted in the desired time is confirmed. CONSTITUTION:An oscillating circuit 1 is adjustable in its reacting time to signals and higher the oscillating frequency is, faster the reacting time. A counter 2 counts the output of the circuit 1 and decides a time to maintain an output signals (d). At a time (a), because the count value is initialized by a pulse (e) from an AND gate 4 before the count value of the counter 2 is full, no pulse (f) occurs, but at a time beta, the count value is made full, thus producing a pulse (f). This pulse (f) changes the output signal (d) of a latch circit 5 from a high output to a low output, and an initial signal pulse (g) is inputted, then the output signal goes to low to be released.

Abstract: PURPOSE:To reduce the voltage standing wave of an output terminal for a branching device of the common hearing system of a TV receiver, by connecting the polarities of the primary and secondary windings of a transformer adverse to each other and grounding the output terminal via a capacitor to compensating a delay of position. CONSTITUTION:An end of a primary coil 9 of a transformer 8 is connected to an input terminal 2, and the other end of the coil 9 is connected to another output terminla 4. An end of a secondary coil 10 is connected to a branching output terminal 6, and the other end of the coil 10 is grounded. If the noise, etc. is given to the terminal 6, this noise flows toward an arrow mark 11 via a resistance R1 and the coil 9. At the same time, the noise given from a load 7 and to be applied to the terminal 6 flows to the coil 10 and in an adverse direction to the arrow 12. This noise induces the voltage adverse to the arrow 11 at the coil 9 and is eliminated by the coil 9. As a result, no noise is delivered to a load 5 from the terminal 4, and furthermore the voltage standing wave is reduced at the terminal 4 since an end of a capacitor CO is grounded to compensate a delay of phase.

Title: Flexible hose
Inventor: ANN BESHIE
IPC: F16L11/08
Filed: 1985-01-17
Abstract: A flexible, very high pressure hose as a flexible conducting member in hydraulic systems. The wall of the hose contains filamentary load-carrying cords which are embedded in two or more layers. The load-carrying cords are combined to form a plurality of strips which cross one another or are braided with one another. The present invention deviates from the heretofore known symmetrical arrangement where the strips of a given layer have the same number of load-carrying cords in both directions, and instead provides an asymmetrical layer construction including strips which in one direction have a different number of load-carrying cords than do the strips which extend in the opposite direction. While the local resistance to pressure remains the same, the advantages of the present invention are distinct improvements, primarily in the flexibility and the service life of the novel hoses.

Abstract: PURPOSE:To obtain an excellent anti-scratching property and frictional characteristic by laminating thermoplastic resin containing particles at least on one surface, and permitting the relation between the particle size and the lamination thickness, and the radius of curvature in projection tips to be in a specific range. CONSTITUTION:The film is formed such that thermoplastic resin A containing particles is laminated at least on one surface, and they are biaxially oriented thereafter.
