Abstract: PURPOSE:To efficiently and economically attain the connection between communication equipments. CONSTITUTION:In the case of a digital cordless telephone system telephone terminals 202a and 202b transmits signals 16a and 16b to an antenna part 105a by using different frequencies for each call. A frequency division multiple signal 14a received by the antenna part 105a is light source-modulated by an E/O converter 103a, and an optical modulated wave 12a of a wavelength 25 is transmitted. The optical modulated wave 12a is synthesized with other optical modulated waves 12 and 12c whose wavelength is different from a data communication system and a radio LAN in multiplexer 101a, and inputted through a first optical fiber transmission line 11a to a branching filter 102c at one floor, and branched. A branched optical modulated wave 13g is converted into an electric signal by an O/E converter 104, and outputted as a radio frequency band signal 15g. The radio frequency band signal 15g is radiated as an electric wave from an antenna 105e, and received by a base station 112.

Title: Torque detector for motor-driven tool
Inventor: TOTSU KATSUYUKI
IPC: G01L3/14
Filed: 1985-12-27
Abstract: PURPOSE:To detect torque at the time of the operation of a clutch with high accuracy, by combining a torque detection mechanism with a clutch mechanism part. CONSTITUTION:When the opposite load applied to an internal gear 12 through a follower shaft 20 increases gradually, said opposite load is acted on a torque detection disc 50 through a steel sphere 32 constituting a clutch mechanism to revolve the same around a support shaft 48 and applies screw stress to a torsion bar 58. This screw is detected as a torque value through a strain gauge 60. When the opposite load transmitted to the internal gear 12 increases, a sleeve 36 is pushed down to an axial direction against the pressing force of a coil spring 40 with respect to the steel sphere constituting the clutch mechanism to allow the internal gear 12 to race and, by measuring the torque max. value at this time, it can be confirmed whether an electromotive tool completed work on the basis of a proper torque set value.

Title: Production of ferritic stainless steel excellent in high-temperature oxidation resistance
Inventor: NABESHIMA YUKI
IPC: C22C38/18
Filed: 1989-11-15
Abstract: PURPOSE:To stably produce a ferritic stainless steel excellent in high-temp. oxidation resistance by specifying CaO/Al2O3, by weight, in slag and the proportion, by weight, of (SiO2+MgO+MnO) in the slag, respectively, at the time of regulating Al content in the steel. CONSTITUTION:In the refining of a ferritic stainless steel containing >=3.0wt.% Al, Mg concentration in the steel can be lowered by reducing MgO concentration in the slag at the time of Al addition, but the increase in Si and Mn concentrations in the steel cannot be prevented, and further, a large amount of Al2O3 is formed in the course of refining and, as a result, the melting point of the slag is elevated. In order to remove the above problems, respective concentrations of SiO2 and MnO as well as the concentration of MgO in the slag are reduced and CaO/Al2O3 in the slag is regulated to 0.8-1.2, and further, the proportion of (SiO2+MgO+MnO) in the slag is regulated to <=5wt.%. By this method, stable refining can be carried out while controlling the melting point of the slag to low degree and keeping respective concentrations of Si, Mn, and Mg in the steel at low degrees.
