Title: Avalanche diode
Inventor: TAKESHIMA MASUMI
IPC: H01L29/864
Filed: 1977-10-18
Abstract: PURPOSE: To establish the oscillation of high efficiency with lower operation voltage than conventional GaAs homo junction diodes, by forming the hetero junction diode taking the drift region to GaAs and the avalanche region as Fe.  
     CONSTITUTION:  On the n ++  GaAs 1, the n Ge layer 4 and p ++  Ge layer 5 of 0.1 to 0.3μm, and n +  GaAs layer 3 1 to 10μm including donor of concentration 1×(10 14  to 10 15 ) are formed. When the inverse voltage is applied to the diode, avalanche is caused from the crystal internal electric field, causing microwave oscillation. When the DC voltage drop is Va for the avalanche region and Vd for the drift region, the oscillation efficiency of diode is increased as smaller Va/Vd. When the drift region is nGaAs, the efficiency is expressed as η=2/πx (Vd/Va+Vd). When Ge-GaAs hetero junction, Va/Vd≈1.1η≈0.3, and the operation voltage is less than conventional methods and the oscillation of high efficiency can be made

Filed: 1988-05-25
Abstract: PURPOSE:To suppress the deterioration in the reception sensitivity due to extinction ratio and optical fiber transmission waveform distortion by providing an optical filter to eliminate an optical spectrum corresponding to off-level of light intensity into an optical transmission line. CONSTITUTION:An optical filter 3 is inserted in the system, only an optical spectrum corresponding to the on-level is segmented and the optical spectrum corresponding to the off-level is eliminated. The optical spectrum corresponding to the off-level is eliminated in the optical pulse waveform as shown in figure (a) to eliminate the luminous intensity of off-level, the extinction ratio is takes large sufficiently and the deterioration in the reception sensitivity is avoided. Moreover, the off-level is decreased, then the optical intensity amplitude is increased by the decrease and a large luminous intensity amplitude is obtained by a small modulation current amplitude. Furthermore, the optical spectrum is a single peak narrow spectrum in existence in the wavelength corresponding to the on-level as shown in figure (b), then the optical fiber transmission distortion is reduced largely.

IPC: B60C11/11
Filed: 1982-07-21
Abstract: PURPOSE:To suppress abnormal abrasion without reducing performance of traction by parallelizing side walls of longitudinal grooves with each other on the periphery of the tread.
