Abstract: PURPOSE:To prevent the film characteristic of an Al alloy film from being degraded when a Ti film used as a substratum and the Al alloy film is heated and made to flow so as to fill a connecting hole. CONSTITUTION:An interlayer insulating film 4 is formed on a first Al interconnection 3, a connecting hole which reaches the first Al interconnection 3 is formed, and a Ti film 5 and an Al alloy film 6 are formed sequentially by a sputtering method. Then, a silicon substrate 1 is heated to 450 to 500 deg.C, the Al alloy film 6 is made to flow, and the connecting hole is filled. At this time, the thickness of the Ti film 5 is set at 10% or lower of the thickness of the Al alloy film 6, and it is to be at 25nm at the maximum. Especially, in the case of the Al alloy film 6 which does not contain Si, the thickness is set at 5% or lower. Thereby, the degradation of the film characteristic of the Al alloy film due to Ti is reduced to a minimum, and the connecting hole can be filled surely.

Abstract: PROBLEM TO BE SOLVED: To enhance conductivity, decrease voltage drop caused by internal resistance, and provide a battery with high capacity and high output by arranging a positive active material, a conductor made of carbon fibers, and a binder on a current collector to form an electrode. SOLUTION: In this electrode 18, preferably, carbon fibers are made of fibrous graphite, the diameter of carbon fibers is 1-15 μm, the length is 20-100 μm, and when the total amount of a positive active material, a conductor, and a binder is 100 wt.%, the amount of the conductor is 1-10 wt%. Since the conductor 12 is fibrous, the contact surface area with a positive active material 10 and a current collector 16 is made larger compared with a granular conductor. Since the carbon fibers coming in contact with the current collector 16 are bent between the positive active materials 10 and extended to the surface of the electrode 18, sufficient current paths are produced even in the positive active material 10 not directly coming in contact with the current collector 16.  The conductivity of the positive electrode is enhanced, voltage drop caused by internal resistance is decreased, and stable, high output is obtained even at high current.

Filed: 1988-12-06
Abstract: PURPOSE:To easily measure a distance in real time by imposing frequency modulation on continuous wave laser light and finding the distance from the beat frequency between output laser light and reflected laser light from a body to be measured. CONSTITUTION:A laser light output means 111 outputs the continuous wave laser light which is frequency-modulated by a frequency modulating means 113. Part of the laser light is supplied directly to a detecting means 115 and the rest is outputted to the body 101 to be measured. Then reflected laser light reflected by the object 101 is photodetected by a photodetecting means 115. The means 115 detects the beat frequency between the outputted laser light and reflected laser light and supplies it to an arithmetic means 117. The detecting operation for the beat frequency is performed for a desired period under the control of a control means 116. The means 117 finds the distance from the beat frequency. Thus, even when the body to be measured or measuring instrument is in motion, the distance is easily measured in real time.

Title: Manufacture of silicon carbide semiconductor device
Inventor: RAJESH KUMAR
IPC: H01L21/336
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of breakdown strength in a P-N junction part by eliminating the defects of an impurity layer formed by ion implantation. SOLUTION: An impurity region 30 is formed by ion implantation of B, which are p-type impurities, to an n--type epitaxial layer 2. A surface layer part of the impurity region 30 is removed. Consequently, a surface layer part whose crystallinity is not disturbed is removed, and a part whose crystallinity is disturbed is left by ion implantation. Then, when a p-type base region 3 is formed by activating B, recrystallization occurs only from the position side of deepest ion implantation. As a result, crystal defects are not left in the p-type base region 3 and lowering of the breakdown strength in a P-N junction part of the p-type base region 3 and the n--type epitaxial layer 2 can be prevented.

Title: Coating film and method for forming same
Inventor: ARUBAATO JII TOBIN
IPC: C23C14/58
Filed: 1991-09-16
Abstract: PURPOSE: To apply an oxidation resistant face on a metal used at high temps.  
     CONSTITUTION: An oxidation resistant face having ductility is formed on titanium aluminide and a titanium alloy, and furthermore, a heat resistant metal- diffused barrier layer metallurgically compatible with the alloy substrate is introduced therein. This diffused layer is coated with an intermediate copper bonding layer. This copper layer is coated with nickel or nickel-base superalloy. If required, by using a fourth protective layer of iron-base superalloy, even if it is exposed to a high temp. environment causing oxidation, oxide scales capable of protecting can be formed. Moreover, this fourth layer can be composed of nickel aluminide which is an oxidation resistant outside layer. In this way, the oxidation resistant face can be formed on the metal used at hig temps., and furthermore, even if exposed to oxidation at high temps., the embrittlement of the alloy caused by deterioration in the mutual action between the coating film and substrate can be prevented.

Then, when an inclining cylinder 9 is worked and the end parts of the guide rails 10 are lowered to incline the guide rails 10, the press roll is rotated and moved in the transverse direction and is stopped in collision with a stopper 29.  After the press roll 5 is exchanged, the press roll 5 is rotated to the upper part of the supporting stage 30 by inclining the guide rails 10 and is elevated by means of the press cylinder 7.

Filed: 1992-11-19
Abstract: PURPOSE:To reduce the effect of disturbance, and to improve the transient characteristic of a synchronous noise by correcting a gain so that the sum of squares of an error between the waveform of the inputted synchronous noise and the output waveform of a synchronous filter. CONSTITUTION:A pulse generator 11 divides the synchronization of the inputted synchronous noise by the number N of taps of a synchronous filter 12, and generates a sampling enabling pulse, and the filter 12 successively outputs the N pieces of taps synchronously with the pulse. The output of the filter 12 is added to the noise, and a filter coefficient correcting means 13 updates the tap value of the filter 12 so that the addition error becomes small. Next, the sum of squares of the difference between the output waveform of the filter and the waveform of the input noise is searched on the assumption that each tap of the filter 12 is multiplied by a gain (g) each time the pulse generated once in one cycle of the synchronous noise from the synchronous noise generating means 14 is inputted, and a filter gain correcting means 15 decides the gain (g) so that the sum of squares becomes minimum. Thus, the transient characteristic of the synchronous noise can be improved.
