Title: Method for quantitative analysis of carbon
Inventor: TANIGUCHI HIROSHI
IPC: G01N23/22
Filed: 1985-09-06
Abstract: PURPOSE:To accurately calculate the quantity of carbon, by using diamond and graphite as standard specimens and calculating a diamond ratio and a graphite ratio from the secondary radiation measuring signal of an unknown specimen according to a predetermined formula. CONSTITUTION:Both of diamond and graphite are used as standard specimens and secondary rediation measuring signals obtained when radioactive rays were irradiated are calculated with respect to diamond, graphite and an unknown specimen. For example, the peak position (a) of diamond, the peak position (b) of graphite and the peak position (c) of the unknown specimen are calculated from the signal wave forms of said measuring signals. Next, the diamond ratio and graphite ratio of carbon in the unknown specimen are calculated from the peak positions and, further, the intensities of the carbon signals of diamond and graphite are measured and the carbon composition value of the unknown specimen is calculated from said intensity values according to a predetermined formula. Because diamond and graphite are used as standard specimens, the content of carbon in the unknown specimen can be accurately calculated.

Title: Transmission line switching system
Inventor: IYAMA HIROYUKI
IPC: H04Q3/52
Filed: 1992-07-24
Abstract: PURPOSE:To secure exchange service for a subscriber at early stages by switching a subscriber line connected to a faulty exchange to a spare exchange side when it is judged that it is hard to restore the exchange due to the significant fault of a telephone exchange. CONSTITUTION:For example, when the significant fault occurs in an SWE 11, an SBY 10 succeeds call processing from an SOB 61 via an RT 51 and an optical cable 41. In other words, a time slot (pass) between ports (a) and (b) shown in continuous line is switched to the pass between the ports (a) and (c) shown in broken line in a TDS 31. When it is judged that the faulty state of the SWE 11 will continue for a long time by a maintenance engineer, a control signal is inputted from a CLT 32, and the pass from the optical cable 41 is switched from the pass between the ports (a) and (b) to the one between the ports (a) and (c).

Thus, a pulse width discriminating section 8 comprising a pulse width count section 11 and a CPU12 discriminates whether the data content is ''0'' or ''1'' by the CPU12 by counting the pulse width of the ''H'' and ''L'' period of the voltage level data to form transmission date. A return signal is extracted by a current transformer CT as a changing point detecting signal and outputted as a changing point detecting pulse by a return current changing point detecting section 6. Further, the current level data is formed, the pulse width is discriminated by a pulse width discriminating section 10 and the return data is formed.

Title: Ultrasonic wire boding method
Inventor: OISHI TOSHIHIKO
IPC: H01L21/607
Filed: 1990-07-26
Abstract: PURPOSE:To enhance strength at the bonding neck part and to reduce the area necessary for bonding by gradually increasing the load and ultrasonic power to be applied at the time of bonding. CONSTITUTION:A wedge 9 lowers and stops when an A wire 10a comes into contact with a semiconductor chip 11. Load and ultrasonic power are then increased gradually thus bonding the A wire 10a to the semiconductor chip 11. Since the initial contact area 12 is reduced drastically, collapse width required for achieving same bonding strength as conventional one can be made narrower. In other words, noncontact area, i.e., initial contact area, is reduced by gradually increasing the load and the ultrasonic power at the time of wire bonding.
