Title: Optical branching circuit
Inventor: SATOU TOYOSAKU
IPC: G02B6/122
Filed: 1979-08-16
Abstract: PURPOSE:To achieve highly reliable optical branching circuit having excellent branching property, by forming light guide paths upon the substrate made of either plastics or glass, etc., by the photographic means, using photosensitive resin having higher refractive index than said substrate, and also by forming optical branching circuit by covering the light guide paths with transparent material having lower refractive index than said paths. CONSTITUTION:Smooth substrate 1 made of either transparent resin, glass or quartz glass, is coated with photosensitive resin such as polyester base or polyurethane base, and covered with ''MYLER (R)'', and the glass mask is tightly set over said surface, and the resin is then hardened by irradiation of ultraviolet rays. Light guide paths 2 are then formed by alkal etching. Optical fibers 4-51 are then coupled together by having respective axes aligned along the side surfaces of said light guide paths 2 which are then covered entirely with transparent material 3 such as setting resin having lower refractive index than the photosensitive resin. After hardening, the optical branching circuit is thus accomplished. Accordingly, highly reliable optical branching circuit having excellent branching propertu is realized.

IPC: H03F1/52
Filed: 1988-04-26
Abstract: PURPOSE:To prevent the occurrence of an abnormal waveform even with an inductive reactance loaded to the circuit by operating a protection circuit only at a prescribed case. CONSTITUTION:If, e.g., a noninverting output terminal 6 is short-circuited to a negative power supply terminal 9, a short-circuit current flows to a transistor(TR) 1 but does not flow to a TR 4, then TRs 24, 37, 49 to 52 are conductive, a drive current of the TRs 1 to 4 is limited and the destruction is prevented. In case of normal operation, since an identical current flows to the TRs 1, 4 and the TRs 2, 3 even if the phase of the output current differs, no difference is caused in the base voltage of the TRs 21, 22 and the TRs 30, 31, a TR 37 is not operated and no protection is implemented. Thus, no unrequired protection is executed even with an inductive load and no abnormal waveform is caused between the noninverting output terminal 6 and an inverting output terminal 7.
