Title: Semiconductor photodetector device and method of manufacturing the same
Inventor: TAKAOKA KEIJI
IPC: H01L31/0304
Filed: 1990-01-12
Granted: 1993-09-21
Abstract: Abstract of the Disclosure Disclosed are an avalanche photodiode and a manufacturing method thereof.  An n?-type InGaAs light absorption layer and n?-type InP window layer are formed on an n-type InP substrate by crystal growth, in the order mentioned.  A depression is formed in a selected surface portion of the window layer, and n-type impurities are doped into the bottom of the depression, to thereby form an n-type high concentration region.  Further, n?-type crystal-grown InP layer is formed in the depression in such a way as to fill the depression.  A guard ring is formed around the depression by the doping of p-type impuri-ties.  By doping p-type impurities into the window layer, a p-type high concentration region is formed in the window layer in a manner completely surrounding the interface between the n-type high concentration region and the crystal-grown InP layer.  The n-type and p-type high concentration regions define a junction serving as a light-receiving region.  Since the inter-face of the crystal-grown InP layer, which may not have a satisfactory crystalline structure, is located within the p-type high concentration region, that interface is not supplied with a high electric field during use.          Accordingly, the performance of the avalanche photodiode is not influenced by the interface.

Title: Amplifier device with coupled surface emitting grating
Inventor: TODA MINORU
IPC: H01S5/00
Filed: 1990-03-15
Granted: 2000-05-02
Abstract: A surface emitting grating is coupled to an optical amplifier and has grating elements tilted non-normal relative to the amplifier optical axis. The angle of tilt in one embodiment is such that the grating reflections are refracted out of the amplifier region. The amplifier may have a tilted light receiving end serving as an input port in a second embodiment to cause internal reflections from the grating to be reflected to an amplifier boundary at an angle greater than the critical angle to cause the reflections to pass out of the amplifier region.      In the latter embodiment, the grating tilt angle is minimized to reduce the surface emission beam ankle tilt from the normal to a relatively small angle.

Title: Alternate destination call redirection for telecommunications systems
Inventor: FREY ALAN E
IPC: H04M3/54
Filed: 1990-08-13
Granted: 1994-06-21
Abstract: ALTERNATE DESTINATION CALL REDIRECTION    FOR TELECOMMUNICATIONS SYSTEMS Abstract This invention relates to apparatus and methods for redirecting calls from a first choice destination to some alternate destination if the call cannot be conveniently completed to the first destination. A call is initially extended through a toll network toward the first destination; if the toll network is congested and cannot reach an egress switch to access the first destination, or if a local exchange network connecting the first destination to the toll network is congested, or if a firstdestination PBX cannot be reached from the toll or local network because all access channels thereto are blocked, or if the first destination PBX is congested or attendants are unavailable, an indication that the call cannot be completed to the first destination is sent back to the ingress switch to the toll network for that call. The call is then redirected from the ingress switch of the toll network to an alternate destination. In some cases, this alternate destination may be the same as the first destination but accessed from a different egress switch of the toll network. Advantageously, this arrangement allows calls to be completed to an alternate destination regardless of the reason why the call cannot be completed to the first choice destination. If the first choice destination is a program-controlled PBX, the PBX can be programmed to reject certain types of calls according to the traffic load being handled by the PBX and the particular staffing available at a certain time. Thus, for example, the PBX could be arranged to accept calls for new orders but to redirect calls requesting information about shipments if the staffing of the first choice destination is relatively low. The reason for rejection can be used for altering the choice of an alternate destination or for canceling a potential redirection.

Title: Process and device for elimination or reducing harmonics and/or resonance oscillations
Inventor: STEMMLER HERBERT
IPC: H02M5/45
Filed: 1991-11-25
Granted: 2000-08-01
Abstract: Process and device for eliminating or reducing harmonics and/or resonance oscillations An a.c. machine (7) with, connected in parallel thereto, a capacitor bank (CR, CS, CT), which are fed by a converter (1 - 4) with a d.c. intermediate circuit, form a resonant system which is excited by the rectangular current of an inverter (4) of the converter. In this case, there is superimposition of the fundamentals and the normal harmonics in the machine voltage and in the machine current of an additional harmonic with the frequency of the resonance point. In the lower speed range of the a.c. machine (7), this excitation is eliminated by an optimum operating sequence of current gaps, which are generated inside a current block by means of a quenching circuit (3).      Current gaps are generated at the start and end of each current block for the purpose of damping the 11th and 13th harmonic, and in the middle of the current block for the purpose of damping the 7th harmonic. A turn-on angle basic value signal (.alpha.M) is modified by a turn-on angle differential signal (.DELTA..alpha.M) for the purpose of damping the 5th harmonic, in particular an exciting or available harmonic being controlled to 0 or in the vicinity of 0.
