The directional coupler switch is configured by a parallel waveguide including a first region which is subjected to a nonlinear action and a second region which is not subjected to a nonlinear action. A dispersion relationship of the first region is varied due to the nonlinear action to switch over an exit of light entering from an input side to cause the switch to function as an optical switch. A dispersion curve of the first region has: a region of a constant frequency in one of an even mode and an odd mode which are two kinds of eigen modes of the parallel waveguide; and a region in which gradients of the two eigen modes at frequencies belonging to a region other than the region of a constant frequency are substantially equal to each other. The gradients of the two kinds of eigen modes indicate monotone decreasing or monotone increasing.

A fuel injection pump 100 comprises a thermoelement CSD 47 for advancing injection timing in a cold temperature condition. The CSD 47 uses a piston 46 for opening and closing a sub port 42 formed in a plunger barrel 8. An electronic governor 2 is provided with a mechanism for decreasing an injected fuel quantity when an engine starts in a cold temperature condition. The mechanism shifts a rack position in a fuel-decrease direction in a cold temperature condition, and switches the rack position to a normal position in a normal temperature condition. A timing TR for shifting the rack position is set before or simultaneous to a timing TC for switch-off of the CSD 47.

A frequency multiplexing control system includes a first modem unit connected to a transmission line, and a second modem unit connected to the transmission line. The first and second modem units communicate with each other via a plurality of primary channels and a secondary channel. The primary and secondary channels have different frequency bands. A plurality of signal detection units are respectively provided in the first and second modem units, to detect an abnormal primary channel and send to the second and first modem units, information concerning the abnormal primary channel via the secondary channel. A plurality of disabling units are respectively provided in the first and second modem units, to disable the abnormal primary channel in response to the received information and to send a training signal for recovering the abnormal primary channel to the transmission line.

A high precision stepping aligner includes a stage for carrying thereon an object and drivable to move the object stepwise relative to an exposing position so as to align a plurality of portions of the object in succession with the exposing position, where each of the portions is exposed to exposure light. The stage is moved stepwise first in the X-direction and then in the Y-direction. Thereafter, the stepping movement in the X-direction and the stepping movement in the Y-direction are repeated one after another so that the stage traces a substantially spiral stepping pattern. A mirror for reflecting a beam of light for positioning the stage is disposed on the stage with a heat insulating material interposed therebetween.

A start assister (10) of a fuel injection pump, comprising a piston (46) inlayed into a housing (H), an upper chamber (49) formed over the piston (46), lower chamber (48) formed under the piston (46), wherein a sub port (42) is opened and closed by sliding of the piston (46), and a fuel injection timing is advanced by closing the sub port (42). A thermo-element (61) for sliding the piston is arranged on one side of the piston (46) in sliding direction. A telescopic pin (61a) of the thermo-element (61) is arranged in a low-pressure chamber (50) divided into the upper chamber and the lower chamber, and a connection pin (62) is interposed between the telescopic pin (61a) and the piston (46).

A method of determining an optimum condition of an anti-reflective layer upon forming a resist pattern by exposure with a monochromatic light, forms the anti-reflective layer with these conditions and forms a resist pattern using a novel anti-reflective layer. The method comprises (I) forming an equi-contour line for the amount of absorbed light regarding a photoresist of an optional film thickness using the optical condition of the anti-reflective layer as a parameter, (II) conducting the same procedure as in (I) above for a plurality of resist film thicknesses, (III) finding a common region for the amount of absorbed light with respect to each of the traces obtained, thereby determining the optical condition for the anti-reflective layer, (IV) applying same procedures as described above while changing the condition of the anti-reflective layer, thereby determining the optical condition for the anti-reflective layer, and (V) determining the optimum optical condition such as the kind and the thickness of the anti-reflective layer under a certain condition of the anti-reflective layer.

摘要:
A communication system in which a plurality of multipoint connected satellite stations are connected via down line and an up line to a master station. Each of the satellite stations monitors presence or absence of occurrence of an abnormality in the down line, judges whether the abnormality is present or not and, where the abnormality is present, informs the master station of the nature of the abnormality via the up line. In turn, the master station monitors presence or absence of an alarm indicating abnormality from each of the satellite stations, judges whether the alarm is detected or not and, where the alarm is detected, reads past record information concerning abnormality detection in the satellite station concerned and information on retraining execution time, then judges whether the down line is normal or not and, where the down line is normal, sends a training signal again to the down line to retrain a MODEM corresponding to the satellite station concerned. Accordingly, it is possible to quickly restore demodulation processing by each of the satellite stations to a respective normal status after a recovery of trouble in a down line.
