IPC: H01S5/00
Filed: 1981-11-11
Abstract: PURPOSE:To obtain the laser in which a lateral mode oscillation is controlled in excellent reproducibility by a method wherein a convexed region is provided on the surface of an InP substrate having a (100) surface, while said convexed region is converted to a concavity by performing a meltback, convexed regions are generated on both sides of the concavity, a photo waveguide region is formed on either of the concavity or the convexity, and the damaged layer due to heat on the surface of the substrate is eliminated. CONSTITUTION:A mesa stripe 10 is formed on the surface of the InP substrate 1, having the surface (100) or that which is approximate to it, in parallel to (100) direction, and said mesa stripe 10 is meltbacked at 630 deg.C using an In solution (d) wherein P is melted in a non-saturated state. Through these procedures, a groove is formed corresponding to the position of the stripe 10 by performing a meltback at a slow speed, and mesa stripes 12 and 13, which were turned to a convexed shape on the circumference of the groove, are formed. Subsequently, on the whole surface including said mesa stripes 12 and 13, an n type InP buffer layer, a non-doped InGaAsP active layer, a p type InP clad layer, an n type InGaAsP cap layer and the like are laminated, a liquid-phase epitaxial growing process is performed, and the desired laser element is obtained.

Title: Level measuring apparatus having frequency selectivity
Inventor: KASHIWAGI TOSHIHIRO
IPC: G01R29/08
Filed: 1983-09-30
Abstract: PURPOSE:To allow at least one harmonic wave signal to be present in a band pass filter and to automatically perform accurate calibration, by widening spectrum intervals of harmonic wave components outputted from a pulse generator. CONSTITUTION:The oscillation frequency of a local oscillator 5 is automatically set by CPU14 so as to be capable of receiving a signal nearest to receiving frequency among harmonics f1, f2...fn outputted from a standard pulse signal generator 11. That is, among harmonics f1, f2...fn outputted from the generator 11, for example, f3-f8 entering a selected frequency band width BW1 are received but the output levels thereof come to max. values when the harmonic f5 is received at the center of a passing band width BW2. Therefore, CPU14 sets local oscillation frequency so as to bring one harmonic wave signal to the center of the band width BW2. By this method, only one harmonic wave signal is present in a band pass filter and accurate calibration can be performed.

Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of a transition response, when a system is switched from a pull-in operation to a synchronism holding operation by writing a register data value which an initialization circuit calculates in a delay register at the same time as the change of a filter coefficient. SOLUTION: An initialization circuit 40 connected to delay registers 11 and 12, and coefficient multipliers 23 and 24 calculates the data value of the delay register after a change from the data value in the delay register before the change of a coefficient and from filter coefficient values b1 and b2, before and after the change and writes the calculated data value into the delay register so as to set an initial value. When the ratio R of the present delay register data vale is obtained, the input data values A and B and a convergence value are learnt. Even if a filter coefficient value b' is changed, the register convergence value at that time is obtained. By setting the coefficient is switched and the delay register, a transition response which occurs, when only the coefficient is switched, can be avoided.

Title: Order signal transmitting system
Inventor: SUGAWARA MASATOMO
IPC: H04B17/40
Filed: 1990-07-10
Abstract: PURPOSE:To prevent the transmission quality of a main signal from being deteriorated even when an order signal is transmitted by respectively providing specified comparing means and gate means at intermediate repeater stations. CONSTITUTION:At the intermediate repeater station, the order signal from a high-order station is distributed. One distributed order signal is branched at the station itself, and the other order signal is transmitted to a low-order station after superimposing the order signal from the station itself. In this case, when it is detected that the maximum amplitude value of the other order signal is out of a set range, a comparing means 3 transmits a corresponding compared result, and a gate means 4 blocks the passage of the order signal from the station itself by using an impressed control signal and transmits only the order signal from the high-order station to the low-order station. Thus, even when the order signal is transmitted, the transmission quality of the main signal can be prevented from being deteriorated.
