Title: Optical modulator
Inventor: SUSA NOBUHIKO
IPC: G02F1/17
Filed: 1990-05-02
Abstract: PURPOSE:To apply an electric field even in the presence of an electron in a normal state and to enable sufficient optical modulation by utilizing absorption between subordinate bands generated on the interface of junction (heterojunction) between semiconductors which differ in electron affinity, and varying the subordinate band interval by applying the electric field and then putting the optical modulator in operation. CONSTITUTION:The optical modulator is constituted by joining the 1st semiconductor 4 with large electron affinity and the 2nd semiconductor 3 with small electron affinity and a gate electrode 5 for applying the electric field to the interface between semiconductor heterojunction where light is made incident and semiconductor heterodyne junction provided on the side of the 2nd semiconductor 3 at right angles is provided. When a positive voltage is applied to this gate 5, the majority of the positive bias is applied to an AlInAs layer 3 to induce charges (electron) on the heterodyne junction interface. Electrons are accumulated at the ground potential (E0) and when light which has energy E1-E0 is made incident from outside, electrons are excited from the ground potential to an excitation subordinante band (E1) to absorb the light. When the intensity of the electric field which is applied to the heterojunction interface is varied, the energy E1-E0 varies. Consequently, the absorption peak wavelength of the light varies, so the optical modulation by the gate voltage becomes possible.

Title: Schmitt trigger circuit
Inventor: HABUKA TOSHITO
IPC: H03K3/3565
Filed: 1982-07-05
Abstract: PURPOSE:To set up hysteresis characteristics to a required value by connecting a gain adjusting means to a ring-like signal transmission line. CONSTITUTION:If an input signal Vin supplied to an input terminal T1 reaches a voltage higher than a high threshold level, a p-channel MOS FET M11 is turned off and an n-channel MOS FET M12 is turned on. Consequently, Vout is turned to the L level. The output signal of the L level is supplied to the gate of the MOD FETs M13, M14 of an inverter N12 through a line l1. As the result, the FET M13 is turned on and FET M14 is turned off. Therefore, the voltage of a point B is turned to the H level and fed back to the gates of the FET M11, M12 through a resistor R1 and a line l2. When an input signal Vin reaches a voltage lower than a low threshold level, similar positive feedback operation is executed. The hysteresis characteristics are determined by the resistors R1, R2.
