Title: Method for forming aluminum wiring
Inventor: KONDO HIDEKAZU
IPC: H01L21/205
Filed: 1993-03-31
Abstract: PURPOSE:To form an improved aluminum wiring film without forming an ultra- high vacuum state by reducing the pressure inside a reaction container and then prescribing the atmosphere inside a reaction container before film formation so that the partial pressure of a mixed gas consisting of carbon, oxygen, and nitrogen contained inside a residual gas which remains inside the reaction con tainer is less than a specific value. CONSTITUTION:The inside of a reaction container 10 and a transport chamber is set to an ultra-high vacuum of 1X10<-11> Torr or less. After this, various kinds of gases such as the air dry air, and pure argon are sealed in. Then, the gas inside the reaction container 10 is evacuated to a constant pressure by an exhaust device 15 which is constituted of a turbo molecular pump or an ultra-high vacuum pump such as titanium sublimation pump. After that, vaporized DMAH is introduced into the reaction container 10 as a feed gas. After that, film formation is performed. By defining the atmosphere inside the reaction container before film formation in this manner. an improved aluminum wiring film can be formed.

Title: Bulk material storage installation provided with delivery device
Inventor: IIO MIKIO
IPC: B65G65/48
Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the bite of bulk material by forming space hard for bulk material to fall in, in a shift place from a hopper-shaped inclined part to a low flat end part so that the wheel tip of a delivery machine passes through this space part. SOLUTION: A wheel 18 is formed in such a diameter that blades 20 are extended across inclined part extended faces A on the inside of raised parts 4 of a storage tank 1 and that the tips are close to the raised parts 4. As bulk material is discharged, bulk material in an upper layer falls in order on a flat end part 2b, but bulk material falling along the inclined part 2a radially falls into space B of triangular cross section formed by the inclined part extended face A and the raised part 4, after passing the lower end of the inclined part 2a.  Accordingly, the bulk material hardly falls into particularly a part close to the raised part 4 in the space B which the tip of the blade 20 passes through so that there is little possibility of a bite even in case a clearance between the blade 20 and a bottom wall 2 is extremely small in a boundary part between the inclined part 2a and the flat end part 2b.

Title: Semiconductor device
Inventor: MINAMI HIROYUKI
IPC: H01L29/812
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To increase the height from a semiconductor substrate to the upper part of a gate electrode and to reduce gate-source and gate-drier capocitances, by providing a source electrode and a drain electrode on a semiconductor substrate, and constructing a gate electrode located therebetween into an inverted step type cross sectional shape. SOLUTION: A Y shaped cross sectional gate electrode 6 has an inverted step type where a cross sectional shape is gradually increased stepwise in the width toward the upper portion, and includes a lower electrode part 6a fixed to a semiconductor substrate and having width L1 (gate length), a middle electrode part 6b having slightly wider width L3, and an upper electrode part 6c having further wider width L2. Thus, an adjustment of the cross section ensures to form arbitrarily lower gate electrode. The height from the semiconductor substrate 1 to the upper electrode part 6 of the Y shaped cross sectional electrode 6 can be increased to the height corresponding to the total thickness of the resist 2 and the resist 3, and hence gate-source capacitance and gate-drain capacitance can be reduced.

Title: Level comparator
Inventor: HARA MASAO
IPC: H03K3/037
Filed: 1979-06-12
Abstract: PURPOSE: To accomplish accurate level comparison with a simple circuit by switching the high and low level states of the output through the varying of the power source voltage.  
     CONSTITUTION: The terminals 13W15 are respectively connected to the terminals 20W22. Then, when the commercial power source is connected between input terminals 9 and 10, the pulsating current of the charging circuit 7 is applied to the battery checker as the power source voltage. Consequently, the threshhold voltage fluctuates repeatedly with respect to the reference voltage and thus, the input of the S terminal repeates the low and high level states. On the other hand, as the R terminal 34 is grounded through the resistances 25 and 26, it maintains the low level state while the Q terminal moves to the high level state to turn on the light emitting diode 29. Then, when the receiving terminals 17 and 18 of the battery 19 are connected to the connection terminals 11 and 12, a given charging current flows through the battery while the pulsating currange from the charging circuit 7 is smoothed. Thus, the Q terminal is maintained at the H-level state.

Filed: 1983-04-27
Abstract: PURPOSE:To find a zero cross point precisely even when a sampling rate is long by approximating a sine wave signal by a cubic equation, and substituting three sampled values in this cubic equation and performing processing. CONSTITUTION:A sine wave signal y=Asinomegax is represented as a cubic approximate equation y=A(omegax-omega<2>x<3>/6). Then, coordinates x0 and y0, x1 and y1, x2 and y2 of sampling points where three successive sampled values y0, y1, and y2 are different in sign from those of other two sampled values. Then, those three coordinates are inserted in the cubic equation. The distance or time between a zero cross point and the coordinate x0 is calculated from three approximate equations obtained as mentioned above to calculate the position of the zero cross point. Thus, the zero cross point is found precisely even when the sampling rate is long.
