Title: Light emitting element
Inventor: HISHIDA YUJI
IPC: H01S5/00
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a light emitting element, the light emitting wavelength of which can be changed over a wide range without changing the characteristic of the element other than the light emitting wavelength. SOLUTION: A light emitting element is provided with a light emitting section composed of an n-type clad layer 6, a light emitting layer 7, a p-type clad layer 8, and a wavelength converting section composed of an optically pumped n-i-p-i laminated light emitting layer 4. The light emitting layer 4 is formed by alternately laminating a plurality of p-type GaN layers and a plurality of n-type GaN layers upon another. When a voltage is applied across an electrode 9 for driving light emitting section and a common electrode 10, the light emitting layer 7 emits light. The light emitted from the layer 7 is absorbed by the light emitting layer 4 and luminous recombination takes place. When a voltage is applied across the common electrode 10 and an electrode 11 for changing wavelength, and external electric field is applied upon the light emitting layer 4.  The energy of the light generated by the luminous recombination varies depending upon the magnitude or presence/absence of the external electric field.

Title: Optical transmission and reception system and optical reception device
Inventor: FUJITA SHOICHI
IPC: H04B10/077
Filed: 1994-04-07
Abstract: PURPOSE:To automatically optimize the distortion according to the optical input signal level by multiplying and sending two pilot signals with dissimilar frequencies and extracting the mutual modulation distortion component to be generated. CONSTITUTION:A distortion control circuit 14 extracts the mutual modulation distortion component to be generated by pilot signal for two distortion monitor and outputs a signal representing the level value of the mutual modulation distortion component. When an optical input signal 2 becomes higher, a level control circuit 8 reduces the gain of a 2nd gain variable amplifier 4 to keep the level value of a transmission signal 6 constant. At the same time, a distortion control circuit 14 increases and decreases the gain of the 1st gain variable amplifier 3 so that the level value of the mutual modulation distortion component in the transmission signal 6 becomes the level value corresponding to a reference voltage 17. In this case, the gain distribution rate to the 1st amplifier 3 and to the 2nd amplifier 4 is changed and the energy level diagram in the optical receiver is changed. Thus, even when the signal 2 is changed, the energy level diagram in the optical receiving device is automatically changed according to the distortion level of the transmission signal 6 and the transmission distortion is optimized at all times.

IPC: G05D3/12
Filed: 1980-05-27
Abstract: PURPOSE:To detect an overbraking state easily by processing a position signal, outputted as pulses during forward and backward movements, a direction control signal and a position mode signal. CONSTITUTION:In a printer on a digital servo system, pulse signals B and A generated every time a movable member moves forth and back by some extent are inputted to up/down counter 1. The output of the counter 1 is supplied to a dead zone setting circuit 2. The circuit 2 outputs a logic H signal X for seven states in decimal notation or a logic H signal Y for eight states. For example, a direction control signal E having logic H when the movable member moves forth, a position mode signal C indicating a position control area, and a reset signal D are inputted and while the signals C and E are logic H, the signal is not effective. In this case, if the signal is at any position other than logic H and the signal A generates a pulse, a storing circuit 100 outputs a signal T with logic L. When the signal E' of the signal E and the signal C are logic H and the signal D is not effective, if the signal Y is at any position other than logic H and the signal B generates a pulse, a storing circuit 200 outputs a signal U with logic L.
