Abstract: PURPOSE:To provide a semiconductor device having an extremely high durability against heat cycles or against leaving it at a high temperature, by a method in which after an end of a copper based wire is melted to form a ball, the ball is reduced in a reducing gas atmosphere over a predetermined temperature and is then joined to an electrode pad. CONSTITUTION:A copper based wire 5 is cut at the outlet of the capillary 4 with gas flame poured from an oxygen-hydrogen tourch 7 to form a ball 5a at the outlet the capillary 4. Next, the capillary 4 is lowered toward an electrode pad 2A of a semiconductor chip 2 so that the copper based wire 5 can be joined to the electrode pad 2A. In this case, when the ball is formed, the ball temperature is raised over a melting temperature and the semiconductor chip 2 is heated at a desired temperature, for example 300 deg.C, by a heater 3. Since reducing gas 8 is being supplied in the space belot the movable cover 6, the surface of the ball 5a with a temperature above 200 deg.C being placed in the reducing gas 8 is in a reduced state.

Title: Sampling hold circuit
Inventor: FUKUMOTO TOSHIO
IPC: G11C27/02
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To obtain the sampling hold circuit capable of improving a noise characteristic against fluctuation in an input signal and stabilizing an output by providing switch circuits in multistage file. SOLUTION: Under the hold state of the sampling hold circuit 15 by turning off transistors(TRs) T10 and T32 with a changeover signal SH1, a fluctuation X of the input signal generated at a node c appears via a 1st differential circuit (TRs T27-T30) to become its output noise Y. This output noise Y is rather small as compared with the fluctuation X of the input signal. Consequently, noise Z in an output of a 2nd differential amplifier circuit (TRs T05-T08) to which this output noise Y is inputted becomes further smaller. Thus, by providing the differential amplifier circuits in multistage and vertical connection, the noise is greatly suppressed.

Title: Production of synthetic silica glass powder and production of silica glass molded form
Inventor: TAKAZAWA AKIHIRO
IPC: C03B8/02
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain synthetic silica glass powder by hydrolyzing an alkoxysilane wherein the system is cooled to enough low temperatures to prevent evaporated components from condensation/gelation, and by baking the resultant gel so as to suppress the development of black foreign matter and reduce bubbling in the molding process for the silica glass powder in a molten state. SOLUTION: This synthetic silica glass powder is obtained by the following process: a high-purity alkoxysilane such as tetramethoxysilane is hydrolyzed with about 1-10 equivalent times of pure water to form a sol which is then gelatinized at normal or higher temperatures; the resulting silica gel is ground and dried at about 50-200 deg.C into powder about 5-30 wt.% in liquid content and about 10-1,000 μm in particle size; the dried silica gel powder is subsequently heat-treated pref. at 300-500 deg.C or so and then baked at about 1,000-1,300 deg.C; wherein during the hydrolysis process, spots where evaporated components may condensate are cooled to <=10 deg.C (pref. <=5 deg.C or so); thereby affording the aimed synthetic silica glass powder free from any black foreign matter.  The other objective silica glass molded form with extremely low bubble generation is obtained by molding the above synthetic silica glass powder in a molten state.

Abstract: PROBLEM TO BE SOLVED: To make accurately graspable the condition of a road surface by estimating the amount of insolation that the road surface receives according to the position of a structure or the like for shielding the road surface from a solar heat and the position of the sun. SOLUTION: When the insolation from the sun 21 is shielded by a building 22, a shade 24 is generated on a road surface 23.

By measuring the latitude and longitude of the building 22, the height 26, the width 27, the depth 28 of the building 22, and distance 29 of the building 22 from the road in advance and storing them in a database 10; the shade 24 being formed at arbitrary time can be obtained.  By setting the ratio of the amount of insolation of sunshine to that of the shade 24 to the insolation shielding rate, and creating the relationship between the solar position 25 and the insolation shielding rate in advance, the amount of insolation in the shade 24 can be obtained, thus obtaining the amount of insolation at arbitrary time on an arbitrary road surface.
