Title: Semiconductor photo detector
Inventor: YASUDA KAZUTO
IPC: H01L31/107
Filed: 1983-01-27
Abstract: PURPOSE:To increase the speed of response, and to improve modulation frequency-output current characteristics of an optical input signal by reducing or halting the velocity of flow of carriers generated by a hetero-epitaxial junction of a semiconductor photo detector. CONSTITUTION:The forbidden band width of an N type In1-xGaxAsyP1-y layer 13 (where x=y/ 2.197 and y=approximately 0.25 or 0.7) grown on an N<+> type InP substrate 11 has an intermediate value among both an N type In0.53 Ga0.47As light absorption layer 14 and an N<+> type InP buffer layer 12 and the substrate 11. When bias voltage is applied, the maximum energy level E2 of a conduction band in the N type In0.53Ga0.47As light absorption layer 14 is made equal to or lower than the minimum energy level E1 of a conduction band in the N<+> type InP buffer layer 12 under the state of operation of a light-receptor by selecting the thickness of the N type In1-xGaxAsyP1-y layer 13 in the energy bands of these each layer. Accordingly, most of electrons proceeding toward an N side electrode 20 are injected to the N type InP buffer 12 at high speed because the energy bands of these three layers are positioned.

Title: Electromagnetic actuator driving circuit, electromagnetic actuator device, video tape recorder, and projection video displaying device
Inventor: KOJIMA MASANORI
IPC: H02P25/098
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain a driving circuit which is improved in braking ability by negatively feeding back the terminal voltage of an electromagnetic actuator to a driving current control circuit and, at the same time, controlling the driving current of the driving circuit by positively feeding back the terminal current to the driving current. SOLUTION: A driving circuit 100 incorporates a feedback circuit 34 and the feeding- back amount of a voltage varies depending upon the mutual conductance 1/Rf of a current source 31 (where, Rf is the internal impedance of the current source 31) and, in addition, depending upon the product of the converting sensitivity H of a current detector 40 and the inverse number Rf of the mutual conductance of the current source 31. When the mechanical resonance frequency is sufficiently higher than the cut-off frequency of the high-pass filter of a feedback circuit 34, a capacitor 41 is considered to be short-circuiting and an electromagnetic actuator can be braked at an arbitrary Q-value obtained by speed feedback by forming the feedback loop of the circuit 34 and calculating the Q-value, and deciding the feeding-back amount of the speed by selecting (H-1)Rf value.  Therefore, a driving circuit having a high braking ability can be obtained.
