Title: Manufacture of semiconductor device
Inventor: SAITO SATOSHI
IPC: H01L21/3205
Filed: 1989-05-29
Abstract: PURPOSE:To isolate Al, Si from high melting point metal, silicide, to prevent precipitation of ternary alloy and Si and to realize a low resistance contact with heat resistance by employing the high melting point metal and silicide on the contact face with an Si substrate, and inserting an insulating film to Al alloy of its upper layer. CONSTITUTION:TiW, TiN, etc., of high melting point metal is employed as a barrier metal layer 3 in contact with an Si board 1 in the bottom of a contact hole 2a, and an SiO2 film 4b made by rotatably coating with SOG on an Al layer 6 of its upper layer. Accordingly, the layer 3 can be isolated from an Al alloy film 6, and further an impurity diffused layer 1a can be isolated in the hole 2a, thereby preventing ternary alloy of Al-W-Si or Al-Ti-Si from forming on the layer 3. Since the layer 3 is formed to be thick, it can prevent a junction from damaging due to suction of Si of the substrate 1 of its base, thereby performing flattening of the hole after metal wiring.

Title: Metallizing method of ceramic substrate
Inventor: KAWAHARA TOMOYUKI
IPC: C04B41/90
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To provide a metallizing method of a ceramic substrate for forming a metallic layer on the surface of a surface roughened ceramic substrate after surface roughening the surface of a sintered ceramic substrate with an acidic solution or an alkaline solution and a method capable of obtaining the metallic layer having strong adhesion and small variation in the adhesion due to the difference in the location. SOLUTION: After the surface of the ceramic substrate is roughened with the acidic solution or the alkaline solution, an under layer containing Cu and Bi or Cu and V is formed on the roughened surface of the ceramic substrate. Next, the ceramic substrate on which the under layer is formed is heated at a specific temp. range of 600-880 deg.C in an acidic atmosphere and copper oxide existing on the surface of the ceramic substrate is removed by etching to form the metallic layer on the surface of the ceramic substrate.

Title: Slit exposure optical device
Inventor: NAGOSHI MITSURU
IPC: G03B27/50
Filed: 1981-08-31
Abstract: PURPOSE:To allow movable bases of a light weight to follow up a track surface perfectly by inclining the stretching direction of a wire to be put on the movable bases with respect to the track surface thereby generating the components of force pressing the movable bases toward the track surface. CONSTITUTION:Since the installation positions of stationary pulleys 1, 2 are selected in the positions slightly lower than the wire mounting point (a) of the 1st movable base D and the wire winding point (b) of a movable pulley 3, an angle theta1 is formed between the track surface of a guiding member B and the part 6a of a driving wire 6, and an angle theta2 is formed between the track surface and the part 6b of the wire 6; therefore the components of force of the tension T of the wire 6 act downward upon the base D and the base E respectively, by which the bases are pressed to the members B, C. Thus even when the bases D, E are made light in weight, the bases do not float from the members B, C during moving.

Title: Manufacture of semiconductor device and the semiconductor device
Inventor: OZAKI KATSUYA
IPC: H01L21/78
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To prevent generation of shortcircuits due to contact between a bonding wire and a metallic layer by forming a metallic layer selectively inside an isolation groove through an electroless plating method using a catalyst layer, formed in a bottom inside an isolation groove and forming an upper end of a metallic layer lower than an end part of an opening part of an isolation groove. SOLUTION: A catalyst layer 3 on a photoresist layer 2 is removed, and the catalyst layer 3 is left selectively only at the bottom of a first isolation groove 1a. When a GaAs substrate 1 is immersed in an Ni-electroless plating solution, since the rear and the side of the GaAs substrate 1 are far from the catalyst layer 3 which is generated source for atomic hydrogen, hydrogen is not supplied. Therefore, a plating layer is not formed, and an Ni-plating layer 4 can be selectively formed only in an area near the catalyst layer 3, whereto atomic hydrogen is supplied. Thereby, the upper end of the Ni-plating layer 4 is lower than an end part of an opening part 1a, and shortcircuit to the Ni- plating layer 4 can be prevented, even when the surface of the GaAs substrate 1 is subjected to wire bonding.

At the time of injection molding operation when size of a current to the heater 5 is switched over to (heavy) of a heavy current, an amount of radiation through a heater 5a in a linear state (alpha) of the conical part 1 of the tip becomes great. Since solidified or semisolidified stock resin faces on the gate part 1 is a small quantity, the same is melted immediately, what is called the gate becomes closed and injection molding of the stock resin within the cavity is performed. When amount of electrification to the heater 5 is made small again after the injection molding operation, the resin in the gate part 1 is solidified or semisolidified and what is called the gate becomes closed.

Title: Method of supplying internal combustion engine with fuel and engine using the method
Inventor: JIYAN EMIIRU AMEDEI REDERE
IPC: F02M31/16
Filed: 1983-07-27
Abstract: It has been found possible to achieve fuel savings by heating diesel fuel prior to injection to higher temperatures than those currently used, and in particular, for practical reasons, to temperatures in the range 70 DEG  C. to 120 DEG  C. However, to obtain the saving it is necessary to simultaneously modify the volumetric flow rate of fuel in order to maintain its mass flow rate in spite of two factors which tend to reduce the effective mass flow rate with increasing temperature, namely: volumetric expansion; and increased fluidity. Not only is fuel saved by heating to such temperatures, but the maximum power and torque which an engine is capable of delivering are also increased.

Title: Post-attaching seat cover for air bag module equipped seat
Inventor: ITO MINORU
IPC: B60R21/20
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To sew the margin of a together-sewing part as a breaking part to be loosened out and broken by expansion of an air bag, by sewing together the together-sewing parts between a front cloth part and a side cloth part in an air bag module equipping side to be stronger than other general parts and to have tensile strength stronger than that of cloth. SOLUTION: A together-sewing part 3 of a front cloth part 1 and a side cloth part 2 in an air bag module equipping side is sewn with a thick thread, about >=8 of yarn number count, with tensile strength higher than the cloth of a general part using a sewing machine. Since sewing margins 1', 2' for the together-sewing part 3 receive tensile force higher than that margins of other parts receive, the sewing margins 1', 1' of the together-sewing part 3 can be formed as breaking parts to be loosen out and broken by expansion pressure of the air bag though the cover whole parts bear the expansion pressure of the air bag. Consequently the degree of loosening out against the tensile strength of the together-sewn part 3 can be properly adjusted.

IPC: G06F11/10
Filed: 1979-10-25
Abstract: PURPOSE: To make an error in a picture inconspicuous through a simple constitution of circuit and without installing the 1-line delay circuit or the mean value forming circuit, etc., by giving an interpolation to the uncorrectable data with the data which are lower by a line in terms of the space of a field.  
     CONSTITUTION: The video signals converted into the digital signals are formed into blocks, supplied to the input terminals 12A and 12B of the stored digital video signals of 2 channels from the record system and then supplied to the waveform shaping circuit 14 via the regenerating amplifier 13 each. Thus the regenerated signal is turned into the pulse signal, and at the same time the regenerated bit clock is extracted. The data series receive a serial-parallel conversion by the next regenerating processor, and the data and the block synchronous signal are extracted. Thus the data with the time fluctuation eliminated are delivered from the time base collector 16. These output data are supplied to the error correcting decoder 18 via the interchanger 17, and thus each channel data which is regenerated intermittently by the decoder 18 is made continuous via the field memory and then returned to the original tray via the time axis extending circuit 19. In such way, the error of a regenerated picture is made inconspicuous.
