Title: Mode locking laser device
Inventor: MAACHIN II FUAAMAN
IPC: H01S3/06
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To enable a mode-locked double clad fiber laser excited by a wide band diode laser array to generate pulses of the order of picoseconds or femtoseconds. SOLUTION: 560fsec pulses of maximum power 40pJ and wavelength 1560nm are generated by an Er/Yb fiber oscillator 101. 170fsec pulses of 50pJ can be generated in a cavity which is compensated for dispersion. A negative chirp fiber Bragg grating 105 is added so as to improve a cavity in dispersion controllability, whereby pulses of maximum power 1nJ and width 3psec can be generated. A saturated absorber 118 is used to make an oscillator start generating pulses, and a nonlinear polarization development is used for shaping pulses in a normal state.

Title: Four-wheel steering system
Inventor: CHIKUMA ISAMU
IPC: B62D6/00
Filed: 1990-09-07
Abstract: PURPOSE:To simplify a steering system in structure by imparting a steering angle to each rear wheel by means of what is called a compliance steering mechanism which electrically controls the steering angle impartation to the rear wheels only in the case where travel speed is relatively low, and at time of high speed running, imparting the steering angle to the rear wheels on the basis of centrifugal force. CONSTITUTION:In a rear-wheel steering mechanism which installs a worm 21 tight to an output shaft being rotated and driven by an electric motor 19 via a solenoid clutch 31 and displaces a rear-wheel output shaft 11 over in the axial direction by means of rotation of the output shaft 20, current-energization for the electric motor 19 is controlled by a controller 24 inputting each output signal out of a steering angle sensor 8 and a car speed sensor 23. In this case, impartation of a steering angle to each rear wheel 9 by the motor 19 is carried out only when car speed is less than the specified value, and when a vehicle travels beyond the fixed speed, the steering angle is made so as to be imparted to the rear wheels 9 with the same phase as the front wheels on the basis of centrifugal force at time of a course alteration being performed. In brief, the rear-wheel output shaft 11 is supported on a housing clamped to a car body free of some displacement over in the axial direction and in an elastic manner.

Abstract: PURPOSE:To enhance combustion efficiency of materials to be incinerated and minimize the amount of smoke to be discharged outside a main body. CONSTITUTION:When it is necessary to burn an incinerated material T under the condition that the incinerated material T is laid out in a furnace chamber 3, fresh open air is introduced into the furnace chamber 3 from an open air inlet 7 and the air is heated by the combustion of the incinerated material T and passes through an outlet 8 of a partitioning wall and exhausted from a stack 9 by way of a smoke induction chamber 4. The fresh air from the open air inlet 7 is controlled by an open air quantity control device S so as to adjust the open air quantity flowing into the furnace chamber 3. The pressure equilibrium inside the furnace chamber 3, the smoke induction chamber 4 is controlled due to this result so that there remains no incombustible waste. An imperfect combustion gas may be generated during the combustion of incinerated material introduced into the smoke induction chamber 4. However, the combustion takes place inside the smoke induction chamber. This construction makes it possible to minimize the smoke quantity exhausted outside from the stack.
