Title: High output pulse laser device
Inventor: SAKAI TATSUHIKO
IPC: H01S3/08
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To improve the matching of an injected pulse laser beam with the beam mode of an unstable resonator by matching the direction of the injected beam with the beam divergence direction of the unstable resonator. SOLUTION: At least one total reflection mirror 8 is disposed along the way of a positive branch unstable resonator. In this case, a pulse laser injecting hole 5 is not disposed in resonator mirrors 1 and 2, but is disposed in the mirror 8. The direction in which a pulse beam is injected is oriented in the direction in which an instability beam is diverged. According to this configuration, the injected beam has its diverging direction matched with the diverging direction of the unstable resonator, and thus the propagation mode of the injected beam matches with the beam mode of the unstable resonator as much as possible. As a result, efficient amplification can be implemented. Further, this configuration allows a compact device to have a comparatively long resonator length, and hence is suitable for large-output, practical device applications.

Title: Unmanned vehicle
Inventor: MOCHIZUKI HIROBUMI
IPC: A63B55/60
Filed: 1994-08-09
Abstract: PURPOSE:To reduce the burden of a remote operator of an unmanned vehicle that has both autonomous travel and remote operation modes. CONSTITUTION:A CPU 111 detects the position and the state of an unmanned vehicle by various sensors 121-125 and calculates the steering angle and the regulation value concerning the speed of the vehicle based on the detected position and state of the vehicle. In an autonomous travel mode, the steering angle and the target operation value of the traveling speed of the vehicle are calculated based on the traveling route and the position of the vehicle. Then the target operation value is regulated by the regulation value so that the instruction operation value is decided. In a remote operation mode, the instruction operation value given from a remote operation device is regulated by the preceding regulation value. Thus the steering angle and the traveling speed of the vehicle are controlled based on the regulated instruction operation value in both modes. Therefore the regulation is carried out for operation of the vehicle even in a remote operation mode in the same way as the autonomous travel mode. Then inadequate operation for the vehicle is prevented.

Abstract: PURPOSE:To increase the stroke of a piston with no largeness in size further with a large eccentric amount of an eccentric disk by eccentrically forming an eccentric disk mounting part in a shaft of an electric motor to the same direction to the eccentric direction of the eccentric disk. CONSTITUTION:An eccentric disk mounting part 5 is integrally formed on a shaft 3 with a fixed distance eccentrically apart in the same direction to an eccentric disk 6. A flywheel 6a is integrally formed with the eccentric disk 6, and the eccentric disk mounting part 5 is inserted into a hole 7 of the disk 6 and fixed to it by a key 12 and a bolt 13.

Abstract: PURPOSE:To form a contact-wired part of low resistance by applying a CVD metallic film directly to the bottom of an opening without an intermediary of polysilicon CONSTITUTION:After the first polysilicon film 12 has been applying to an SiO2 layer deposited on a semicondcutor substrate 10, a contact hole 13 is made. The surface of this assembly is covered with an SiO2 film 14 and the second polysilicon film 15 is deposited additionally on the surface by means of chemical vapor deposition. If the polysilicon film 15 and the SiO2 film 14 are etched by performing RIE to the assembly, the Si substrate is exposed at the bottom of the contact hole. Then, a tungsten film 16 is formed by coating through chemical vapor deposition. An Al layer 17 is deposited and the wiring of an integrated circuit is completed. Because the Al layer 17 is reinforced with the tungsten film, the wired part is never cut. Because no polysilicon layer is present between the upper film and the Si substrate, the contact resistance value becomes sufficiently low.
