Title: Optical non-linear device
Inventor: TOKUDA YASUKI
IPC: H01L31/108
Filed: 1993-03-31
Abstract: PURPOSE:To obtain carrier accumulation effect with ease and simplify device structure and hence eliminate restrictions imposed to the selection of materials by connecting an electrodes at least on one side with non-ohmic junction. CONSTITUTION:Electrodes 26 and 27 are installed to each of a p side and an n side in p-i-n structure which includes quantum well structure in an intrinsic layer 28. At least one of the electrodes 26 and 27 is coupled with non-ohmic coupling. This non-ohmic coupling can be replaced with Schotkky coupling. Non-ohmic electrode must be used for either one of the electrodes 26 and 27. This construction makes it possible to confine carriers to a satisfactory extent and simplify device structure since there is no need to form an AlAs layer or control the composition of the Al of an undoped AlGaAs confined layer and hence eliminate any materialistic restrictions.

IPC: G04C3/00
Filed: 1981-06-19
Abstract: PURPOSE:To realize the 0sec resetting with a one-touch operation for an electronic watch in which the second and minute hands are driven by different motors, by using a second position detecting circuit and a minute hand correcting circuit to set the second hand at the 0sec position with a one-touch operation as well as to give a correction to the minute hand. CONSTITUTION:When a crown 1 and a push-button 2 are pushed at one time, the 0sec resetting action starts. A main second counter circuit 14 counts the position of the second hand which is driven by the 2nd pulse motor 10 and set the motor 10 at the normal driving of 1Hz when it detect that the second hand indicated the 0sec position. The 1st pulse motor 9 which drives the hours hand  is usually driven with each 20sec. In the 0sec resetting mode, a minute hand  correcting circuit produces a correcting pulse to shift the minute hand onto the minute time in accordance with the movement of the circuit 14. Thus the minute hand is corrected to a correct minute time.

Filed: 1983-05-31
Abstract: PURPOSE:To improve the linearity by inserting a diode for preventing reverse flow to an input stage of each resistor in the DA converter using a ladder type resistance circuit network where each resistor is weighted. CONSTITUTION:Diodes D1, D2,-Dn for preventing reverse flow are inserted respectively to each input stage comprising resistors R, 1/2R-1/2<n>R in the forward direction to the current flow.
