IPC: H03M1/68
Filed: 1978-12-20
Abstract: PURPOSE: To obtain high resolution covering the entire variation range by connecting attenuators to output sides of all of D/A converters except one and then by adding the output of one D/A converter to the output of each attenuator.  
     CONSTITUTION: Digital input 1 is distributed by digital resolving unit 2 to coarse- adjustment D/A converter 3a and fine-adjustment D/A converter 3b corresponding to the number of bits of the input and then converted into analog values respectively. The output of converter 3b is attenuated by analog attenuator 4 according to the distribution ratio and then added to the output of converter 3a by adder 5 to obtain analog output 6. Further, the attenuation rate of attenuator 4 is made greater than the resolution of converter 3a to give hysteresis characteristics to digital inputs to converters 3a and 3b by distributor 2. As a result, even if output 6 would be discontinuous due to the error of converter 3a, converter 3b has upper and lower margins of variation width, so that a fixed value can be obtained.

IPC: H01S5/00
Filed: 1985-07-18
Abstract: PURPOSE:To enable the high-speed direct modulation by maintaining the high efficiency by arranging a reverse applied bias junction and a forward applied bias P-N hetero junction which is different from in a light emitting region, in a buried layer and providing a groove which reaches the reverse bias P-N junction, in the buried layer. CONSTITUTION:A light emitting region (width Wa) of mesa stripe form including a light emitting layer 3 is embedded with semiconductor layers of a P-type layer 6, an N-type layer 7, a P-type layer 8, and an N-type layer 13. The layers 6 and 7 form a reverse applied bias P-N junction. Furthermore, a groove which reaches at least said reverse applied bias junction (the layers 6 and 7) is formed in the buried layer and the buried layer comprises a forward applied bias P-N hetero junction which is different from a P-N hetero junction in the light emitting region composed of the layers 6 and 13. Consequently, a minute leakage current DELTAI flows through the hetero junction of the layers 6 and 13 and the large leakage current flowing the reverse applied bias P-N junction of the layers 6 and 7 is prevented. Accordingly, the high- efficiency operation of laser can be maintained. Also, the whole width Wt of the reverse applied bias P-N junction can be reduced and the remarkable reduction of the junction capacity becomes possible.

Title: Controller for engine
Inventor: HIRAKI HIKOSABURO
IPC: F02D45/00
Filed: 1986-07-04
Abstract: PURPOSE:To avoid the reduction of working efficiency due to the reduction of car speed by increasing the engine output when the load of a working machine increases and the working speed of the working machine is less than a prescribed value, even if an operating lever on the working machine is operated over a prescribed value. CONSTITUTION:A controller 7 reads the allowable max injection quantity corresponding to the number of revolution from the signal N of an engine revolution sensor 3. When the signal of a lever operating quantity sensor 4 on a working machine exceeds a prescribed value and the speed of the working machine which is obtained from the signal of a working machine position detecting sensor 6 does not reach a prescribed value, the controller 7 outputs the second aimed injection quantity which is obtained by increasing the allowable max injection quantity by a prescribed injection quantity, and feedback-controls a control rack 8 by the signal. Since the injection quantity is increased over the allowable max injection quantity, also the engine output is increased over the stationary allowable output, and the car speed is not reduced. When The lever operating quantity does not reach a prescribed value, and the speed of the working machine reach a prescribed value, the injection quantity is not increased.

Title: Brake system for self-reversible diesel engine
Inventor: ANDOU KOUTAROU
IPC: F02D27/02
Filed: 1978-12-22
Abstract: PURPOSE: To stop the movement of ship promptly at reversing rotation of engine, through provision of an air release valve and a brake valve which function such that air in cylinder effects negative work to engine during its idling rotation after fuel supply is interrupted and thereby shorten the time required for lowering the revolutional speed of engine to a level capable of injecting brake air.  
     CONSTITUTION: In stopping movement of a ship in motion rapidly, fuel supply to main engine is stopped at first and brake valve 8 is then opened. Thereupon, air is supplied to a starting air control valve 6 through air passage 13, so that valve 6 is operated in relation with the position of starting cam 7. Resultantly, control air is supplied to the top portion of starting cam 5 from the time when piston is located near the top dead point to the time when it is moved to about 120° position after the top dead point, and starting valve 5 is opened for releasing compressed air in cylinder 3 to the atmosphere via release valve 9. This causes rapid drop of the revolutional speed of engine. When the revolutional speed of engine is dropped to a level capable of actuating brake air, cam shaft is shifted to its reversing position and starting air is supplied to cylinder 3 as brake air with valve 9 being closed and starting-air control valve 1 being opened.
