Patent JP-H0412585-A (JP)
Title: Semiconductor laser
Inventor: YAMAMOTO EIJI
IPC: H01S5/026
Filed: 1990-05-01
Abstract: PURPOSE:To improve oscillation threshold current and modulation characteristics, by reducing reactive current caused by a parasitic p-n junction, by using a high resistive layer or a p-n junction. CONSTITUTION:High resistive layers 14, 15 are formed between a buried layer 7 and a buffer layer 2 and between the buried layer 7 and a clad layer 6, respectively. When this semiconductor laser is operated, carrier is injected into an active layer 5, by the current flowing from an electrode 11 to an electrode 12 through a contact layer 8, the clad layer 6, the active layer 5, the buried layer 7, and a contact layer 9. By the current flowing from an electrode 13 to the electrode 12 through the buffer layer 2, a modulation layer 3, an isolation layer 4, the buried layer 7, and the contact layer 9, the carrier concentration of the modulation layer 3 is controlled, and the refractive index and the absorption coefficient are changed by plasma effect, thus modulating the laser light. Thereby the useless current caused by a parasitic p-n junction is decreased, oscillation threshold is reduced, and modulation performance is improved.

Title: Current transformer protecting device
Inventor: SHIGENOBU MASAHIRO
IPC: H02H7/04
Filed: 1977-09-27
Abstract: PURPOSE: To provide the subject device wherein a discharge gap is used as a protecting device, whereby any abnormal voltage caused by the opening trouble of a secondary circuit of the current transformer is suppressed and simultaneously the secondary circuit of the current transformer is short-circuited accurately protect the current transformer.  
     CONSTITUTION: The fitting terminals 30 and 31 of the protecting device are connected to the secondry terminals 4 and 5 of the current transformer. By opening the secondary circuit an abnormal voltage is generated between the terminals 4 and 5. This voltage is discharged in the discharge gap formed by a movable electrode 13 and a fixed electrode 14. By the discharge energy generated upon this occasion the temperature of a solder 22 joining the electrode 13 and a metal wire 15 to the movable electrode 13 is increased to release the fixture of the metal wire 15. For this reason, a coil spring 16 which has accumulated energy by the tension of the metal wire 15 tends to be restored to its original position. Hence, the electrode 13 is moved toward the electrode 14, and both electrodes are brought into contact with each other to short-circuit the terminals 4 and 5 by the protecting device

Filed: 1991-04-19
Abstract: PURPOSE:To enhance the clamp holding ability in a spring clamp provided with a device for holding a tool holder in a clamped state even when larger unclamping force than clamping spring force acts on the tool holder in a machining center. CONSTITUTION:A draw bar 28 supported in a main spindle 24 is driven upward by clamping spring force, while the draw bar is driven downward to be unclamped by an output part 35 of a pneumatic/hydraulic booster. A piston 11 is inserted into a cylinder 10 fixed to the upper part of a main spindle 24 to form a liquid sealing chamber 12 to the lower side of the piston 11, and the piston 11 is fixed to the draw bar 28. When the draw bar 28 is held in a clamped state, a check valve 56 is closed to seal oil L in the liquid sealing chamber 12.

Abstract: PURPOSE:To make uniform combustion condition in a gas turbine, by calculating deviation of combustion gas temperature in a plurality of combustors, and controlling flow-rate adjust valves provided in fuel supply pipes of the combustors and designed to be independently operated so as to reduce the deviation to zero. CONSTITUTION:Fuel supply pipes 31 connecting a fuel dividing pipe 30 with fuel nozzles 3 include independent fuel-flow adjust valves 32 on the way thereof.

Fuel independently control device 107 receives respective fuel gas temperature signals 106 to carry out operation. If deviation of the fuel gas temperatures is out of the range of continuation of combustor operation, the control device 107 generates a fuel-cut signal 105 to close a fuel-cut valve 12. On the contrary, if deviation of the fuel gas temperatures is in the range of continuation of combustor operation, the control device 107 determines whether or not the deviation is in an allowable limit, and if it exceeds the allowable limit, the control device 107 generates respective fuel independently control signals 108 to open or close the independent fuel-flow adjust valves 32. Thus, combustion condition of the gas turbine may be made uniform.

When the load (d) enters the prescribed range, the estimated value theta and P are defined as the initial values, and a forgetting coefficient lambdamin is set and identified. The coefficient lambda is gradually approximated to 1 as shown in an equation I (mu: constant small enough compared with 1 like 10<-3>, etc.) and the data set in the prescribed load range are regarded as important. Then the relevant value is defined as an identification parameter as long as the load (d) is kept within a range of a fixed disturbance level and at the same time the estimated parameter theta is converged.
