Title: Production of silicate glass having high transmission
Inventor: NISHIZAKI KENICHI
IPC: C03B5/08
Filed: 1984-10-23
Abstract: PURPOSE:In melting silicate glass raw material in a platinum container and molding it, silicate glass having low dissolution of platinum and high transmission is obtained, by carrying out melting and molding in a CO2 atmosphere. CONSTITUTION:The glass 3 having a composition of 31wt% SiO2, 2wt% K2O, 1wt% Na2O, 65wt% PbO, and 1wt% TiO2 is put in the platinum container 2, and placed in the glass melting furnace 1. While the glass is being melted, the CO2 gas 6 is continuously made to flow through the heat-resistant pipe 4 such as quartz pipe, etc., into the furnace 1 at a rate of about 10l/min. Admixture of water into the molten glass can be prevented by setting the desiccant 5 in the middle of the pipe 4. The glass obtained by melting in this way shows >=80% transmission at 423mm wavelength, while glass obtained by melting in an atmospheric pressure has the same transmission at 433mm wavelength.

Title: Semiconductor device
Inventor: INAGI TATSUYA
IPC: H01L23/495
Filed: 1982-12-17
Abstract: PURPOSE:To improve mounting density while inhibiting even the bending of leads by making only the lead width of the end pins of the dual lead type flat package type semiconductor device larger than other lead width only by specific quantities and making spaces among each lead sufficiently larger than the lead width of the end pins. CONSTITUTION:The device is applied and an effect is displayed when the leads are bent remarkably. Consequently, the thickness of the leads is made 0.2mm. or less and lead width except the end pins is made approximately 0.43mm.. The lead width of the end pins has strength through which a bending can be inhibited, and must be kept within a range in which a hindrance is not generated on the improvement of mounting density. The lead width of the end pins is made larger than other lead width only by 0.05-0.1mm. in this respect. The bending of these end pin themselves can be inhibited because the strength of the end pins 11', 21', 31', 41' is increased. The bending of internal leads 12, 13...22, 32, 33...42 can also be inhibited by a guard effect by these end pins because the strength of the end pins 11', 21', 31', 41' is increased.

Abstract: PROBLEM TO BE SOLVED: To highly accurately estimate a fatigue life of a copper material, by obtaining a number of repetition (N) with the use of a specific formula before the copper material breaks when a repetitive stress changing vibrations is applied to the copper material. SOLUTION: Each of a plurality of repetitive stresses is substituted in σof an equation N=(1000/σ)<6.0> or N=(2000/σ)<4.7> or N=(3000/σ)<4.2> , and resulting values N are added, so that a number of breaking repetition of a copper material before the copper material breaks is obtained. Specifically, an axis of ordinate in an S-N curve of a test piece indicates a stress amplitude σ and an axis of abscissa indicates the number of repetition N before the test piece breaks. Both are displayed in logarithmic scales. A break number of repetition when the stress amplitude changes can be obtained if straight lines (B), (C), (D) are used as S-N curves. A fatigue life can accordingly be estimated highly accurately, which enhances a safety factor of products and reduces costs and size.

Filed: 1986-09-19
Abstract: PURPOSE:To improve the accuracy of the operating point of the device for preventing incomplete combustion by separately detecting the electromotive force of a main thermocouple and that of a reverse bias thermocouple. CONSTITUTION:When a current flows from a power source 11 to a control part 15 simultaneously with an igniting operation, an oscillator 16 outputs an AC signal, a main thermocouple 2 is heated by a pilot burner 1, to generate an electromotive force, and the voltage thereof becomes higher than a reference voltage of a reference voltage circuit A17, an AC signal is transmitted from a comparator circuit A18 to a comparator circuit B20. In this case, when the electromotive force of the reverse bias thermocouple 5 is lower than the reference voltage of the reference voltage circuit B19, the AC signal is transmitted to a solenoid valve driving circuit 14, and the solenoid valve 7 is put into an opened state, thus continuing the combustion. At the time of oxygen deficiency, when the electromotive force of the main thermcouple 2 is lowered to a value lower than the reference voltage, the comparator circuit A18 stops AC transmission, and the solenoid valve 7 is closed to stop the combustion. At the time of clogging of fins, when the electromotive force of the reverse bias thermocouple 5 rises up and reaches a value higher than the reference voltage, the comparator circuit B20 stops the AC transmission, and as a result the solenoid valve 7 is closed to stop the combustion and prevent the incomplete combustion.
