Abstract: PURPOSE:To form a diffusion layer uniformly with excellent reproducibility, and to obtain a semiconductor memory having superior yield on manufacture and high reliability by shaping the N-type diffusion layer by arsenic or antimony to the side surface section or base section of a small hole in which a charger storage section is formed. CONSTITUTION:A field oxide film 2 for isolating elements is shaped to a P-type semiconductor substrate 1, an N-type impurity 4 is introduced selectively to the surface of the substrate in a charge storage region through ion implantation by utilizing a photo-resist, the photo-resist is removed, and a small hole is formed through a reactive ion etching method while using a photo-resist 11 patterned again as a mask. An N-type impurity diffusion layer 4 is shaped to the surface of the substrate in the side surface and base of the small hole through thermal diffusion employing an silica film containing arsenic or antimony as a diffusion source. A capacitance insulating film 3 is formed to the surface of the substrate in a capacitance section, and a capacitance electrode 5 is buried into the small hole. A gate oxide film 6 is shaped. The surface of the capacitance electrode 5 is coated with a thick insulating film at that time. A word line 7 is formed, and an N-type impurity diffusion layer 8 connected to a bit line is shaped.

Title: Manufacture of semiconductor device
Inventor: ITAGAKI MASAYA
IPC: H01L21/318
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the peeling of a polyimide film formed on a silicon nitride film which is to be caused by heat treatment, by forming a photosensitive polyamide acid film, in the state that the contact angle of the silicon nitride film formed on a semiconductor substrate satisfies a specified condition. SOLUTION: After a bonding pad 2 is formed on a silicon substrate 1, a silicon nitride film 3 is formed on the whole surface. The contact angle θ of the silicon nitride film 3 is measured by using pure water as a reagent. When the contact angle θ satisfies the condition 20 deg.<=θ<=70 deg., a photosensitive polyamide acid film 4A is immediately formed. When θ<20 deg. or θ>70 deg., the surface of the silicon nitride film 3 is etched by about 5nm by a sputtering method using inert gas like Ar gas, or the silicon nitride film 3 is again thinnly grown. Thereby the condition that the contact angle θ is 20 deg.<=θ<=70 deg. is satisfied, and then the film 4A is formed. As a result, when a polyimide film 4B is formed by heat-treating the film 4A, the film 4b is not peeled from the silicon nitride film 3, because adhesion is improved.

Title: Production of continuously cast ingot having good surface characteristic
Inventor: SHIRAISHI AIMEI
IPC: B22D11/111
Filed: 1985-02-22
Abstract: PURPOSE:To prevent surface flawing with a steel of which the Cp value calculated by the specific equation has a prescribed value by using casting powder contg. C at a high ratio to adjust the Cp value in the surface layer part of an ingot to a specific range. CONSTITUTION:The integranular cracking of the continuously cast ingot is largely affected by the grain size of austenite (gamma) grains and the formation of the coarse austenite (gamma) grains during solidifying and cooling accelerates considerably the intergranular cracking of the ingot. The carbon equiv. Cp of the steel contg. Mn, Ni, Ca and N is calculated by the equation. The Cp value in the surface layer part of the ingot is adjusted to the range higher than 0.23 by using the casting powder having >=(5-6%) and up to about 20% content of C with the steel of which the Cp value is in a 0.13-0.23 range. The Cp value in the surface layer part of the ingot moves to a range where the cracking arises to the smaller extent. The cracking of the ingot is thus prevented.

Title: Multi-station transmission system
Inventor: KAGE GOUZOU
IPC: H04B7/06
Filed: 1978-03-24
Abstract: PURPOSE:To make a high-stability oscillator needless in each transmission station by fluctuating the amplitude of transmission power in respect to time in the multi- station transmission system where the same information signal is transmitted from an antenna at the same frequency approximately. CONSTITUTION:Transmission stations 2 and 3 transmit FM modulation waves; and when transmission information signal x1 from center station 1 is high-level, the wave of a higher frequency is transmitted. Signals x14 and x15 from square wave oscillator circuit 19 are different from each other in polarity by inverter 11, and currents from power supply circuits 6 and 9 of transmission stations 2 and 3 are supplied intermittently to high frequency amplifiers 7 and 10 with different polarities. Transmission radio waves f2 and f3 from antennas 16 and 17 become as shown in figures (c) and (e), and receiving station receices always one of waves f2 and f3. Then, since only one of them is received, influences of interference is eliminated, and demodulation signal x4 can be obtained normally. As a result, a special high-stability oscillator is needless in the transmission station, and the power consumption quantity of the transmission station can be reduced because of intermittent transmission.

Abstract: PURPOSE: To improve the operation efficiency by making the time limit up to the feed of a wire for welding and the stop of an output voltage by a detection signal earlier than normal welding completion, by detecting the buckling of a wire during welding operation.  
     CONSTITUTION: On the completion of normal welding, wire feed stop instruction signal source 1 stops the feed of a wire for welding simultaneously with the inputting of a torch switch signal. Then, time limit circuit 3 stops the supply of an output voltage through output voltage stop instruction signal source 2 a certain time later. On the other hand, a wire buckling prevention device operates during the welding operation to input an operation signal and at the same time, wire feed stop instruction signal source 1 operates to stop the feed of the wire for welding. Then, time limit circuit 4 stops the supply of the output voltage through output voltage stop instruction signal source 2 a certain time later. The delay time of this time limit circuit 4 is shorter than that of time limit circuit 3, so that the feed of the wire and the supply of the voltage will be stopped earlier than normal welding completion.
