Title: Switch circuit and its control method
Inventor: TAKAHASHI YASUSHI
IPC: H04Q3/52
Filed: 1987-01-28
Abstract: PURPOSE:To prevent the increase of a signal delay even for a junction line in the switch circuit of two plates constitution by connecting one or more inputs of the space switch of a first switch to the output of the space switch of a second switch, and collecting junction line signals at the specified output terminal of the space switch. CONSTITUTION:For instance, data are stored in respective read address memories beforehand so that signals adopting a junction among the input signals of B side are outputted to the output ports 6-1, 6-2 of a S-switch by a T-switch 7 and the S-switch 6. Among the input signals, a1, b1, c1 are the junction line signals. The input ports 6-1, 6-2 are connected to the input ports 3-1, 3-2 of the S-switch 3. The signal from A side is connected to the input port 3-3 through the T-switch 12. The signals, inputted to the input ports 3-1, 3-2 and 3-3, are lineset by the S-switch 3 and the T-switch 4, and outputted to B side. Thus, even the signal of the junction line passes through only two steps of the T- switch, and the delay is suppressed.

Title: Spread spectrum signal demodulation circuit and demodulator using same

Filed: 1990-01-26
Abstract: PURPOSE:To prevent mis-discrimination of synchronization by discriminating the synchronization state based on a ratio of outputs passing through a 1st filter means having a nearly equal pass band width to a band width of an information signal and a 2nd filter means having a broader band width respectively. CONSTITUTION:A 1st filter means 7 having a nearly equal pass band width to a band width of an information signal and a 2nd filter means 8 having a wider band width than the pass band width of the 1st filter means 7 are connected to an output terminal of a multiplier means 5. Then a discrimination means 11 discriminates the synchronization state based on the ratio of outputs from the 1st filter means 7 and the 2nd filter means 8. Thus, even when a fluctuation of an input level or a change in the synchronization state takes place, no mis-discrimination takes place. Moreover, since the AGC (automatic gain control) is automatically switched in response to synchronization or asynchronization, the circuit design is implemented independently and the degree of freedom of the design is enhanced.

Abstract: PURPOSE:To protect a diffraction grating against deformation caused by a thermal treatment process by a method wherein an AlP crystal layer is formed on an AlGaInP crystal layer provided onto a semiconductor substrate, grooves are selectively provided so deep as to reach to the AlGaInP crystal to form a diffraction grating. CONSTITUTION:A P-type AlGaInP guide layer 4 is formed, for instance, as thick as 0.1mum or so, and a P-type AlP deformation preventing thin film 5 is formed, for instance, as thick as 50Angstrom  or so through an MOVPE method. A resist film 6 is formed in stripes at a regular interval of 2700Angstrom  through a photolithography technique. A partial chemical etching is carried out using the resist film 6 as a mask. The resist film 6 is adequately set in pitch of stripes and etching depth so as to form a diffraction grating 7 possessed of optional period and depth. Therefore, as a diffraction grating has a deformation preventive thin film at its top, it can be prevented from being deformed even if a second clad layer 8 is formed on its top through an MOVPE method, because an AlP crystal is hardly dissociated in a heat treatment as atoms of a III and a V group are strongly combined together in it.
