Filed: 1990-05-17
Abstract: PURPOSE:To eliminate the generation of the problem of aerodynamic interference between fore wing and rear wing and permit the control of desired motion by a method wherein a missile is provided with a steering wing, provided before a center of gravity, and a propulsion device, provided after the center of gravity and capable of changing the direction of a thrust, whereby the missile is provided with only the steering wing as the wing therefor. CONSTITUTION:The main body 12 of a missile effects horizontal flight by a method wherein a lift is generated by operating a steering wing 1 before a center of gravity 3 by a servomotor 5 and two-dimensional nozzles 8 are operated to direct the thrust T of an engine 4 downward properly while the sum of vertical components of the lift and the thrust is balanced with the weight of the missile. The missile 12 is ascended or descended by changing the lift of the steering wing 1 and the vertical component of the thrust T of the engine 4 in the same phase without changing the attitude of the missile 12. Further, the lift of the steering wing 1 and the vertical component of the thrust T of the engine 4 are changed in reverse phase to change the attitude of the missile and effect up-and-down movement with a small turning radius. The thrust T of the engine 4 is not affected by the back wash of the steering wing 1 and the control of the flight of the missile 12 can be effected correctly and easily.

Title: Semiconductor laser device
Inventor: SHIMIZU YUUICHI
IPC: H01S5/00
Filed: 1983-07-11
Abstract: PURPOSE:To obtain a semiconductor laser device of low noise with small fluctuation of light output by forming a striped current injection region having a part interrupted at the center. CONSTITUTION:The center of a striped Zn diffused region formed on a groove 2 is interrupted. The light generated from an active layer 4 of a current injection region is absorbed to a substrate 1 since clad layers 3 are thin at both sides of the groove 2. Thus, high and low effective refractive index distributions are formed on the groove 2 of the substrate 1 and at both sides along the P-N junction surface of the layer 4, and a basic lateral mode oscillation can be stabilized. The light generated from the layer 4 is propagated in parallel with a current injection region 7 to be amplified to obtain a gain by the injected current. However, since the region 7 is interrupted at the center, the oscillated state having large amplitude at the center as the beat state of two longitudinal modes cannot increase its loss. Thus, the stabilization of the basic lateral mode oscillation and two longitudinal mode oscillation can be suppressed, and single longitudinal mode oscillation can be always obtained.

Title: Machining method
Inventor: NAKANISHI MOTOYASU
IPC: B23B1/00
Filed: 1987-05-23
Abstract: PURPOSE:To enable machined surfaces of a thin thickness cylindrical object to be smoothly finished preventing generation of a chatter, by inserting a gel-state substance layer into a workpiece to be deformed thereafter and machining the workpiece in a condition that this gel-state substance layer is adapted to the internal peripheral wall of the workpiece, in the case of machining a drum or the like for a copying machine. CONSTITUTION:Before a workpiece A is machined, removing an end piece 13 and inserting pressing pieces 14 and gel-state substance layers 15 into internal peripheral space of the thin thickness workpiece A from the side of a shaft-shaped part 161 of a core metal shaft 16, a base piece 12 is fitted to an internal peripheral wall. And mounting the end piece 13 to be placed in the shaft-shaped part 161, the workpiece A clamps its base end by a chuck B in such a manner as to hold the base piece 12 to be placed therebetween, pressing a tailstock C to the end piece 13 from the opposite side. This pressing force deforms the layer 15 in such a manner as to be crushed, but the layer 15, restricting its deformation in the axial direction, generates the deformation in the diametric direction. As the result, the layer 15 is adapted in its peripheral part to the internal peripheral wall of the workpiece. Next when a tool is pressed by rotating a main spindle, generated vibration is transmitted to the layer 15, but an applied vibrative wave, while deforming a gel-state substance, is rapidly separated and changed into a fine state, being converted into heat or the like and absorbed.

Title: D/a conversion circuit
Inventor: ISO YOSHIMI
IPC: H03M1/10
Filed: 1990-05-18
Abstract: PURPOSE:To turn a conversion linearity to be in an ideal state by using a system which doesn't switch the current source of a most significant bit(MSB) near at an output midpoint of a D/A converter. CONSTITUTION:This circuit is equipped with a data conversion circuit 1, a current output type D/A converter 2, an analog switch 3, a current inversion circuit 4, a current/voltage converter 5 and a voltage outputting terminal 6. The data conversion circuit 1 converts an input digital data corresponding to the value of the MSB of the data and outputs the value from the second bit to a least significant bit(LSB) to the D/A converter 2 and at the same time switches the analog switch 3. Therefore, it is possible to prevent the weighted current source from switching near at the midpoint and to prevent a big error from outputting. Thus, it is possible to relize the D/A converter whose linearity is satisfactory.
