IPC: H02N2/00
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a piezoelectric actuator having, no vibration attenuation in a boundary layer of a vibrator and satisfactory propagating efficiency of a vibration energy. SOLUTION: This piezoelectric actuator comprises at least a movable body 11, a vibrator 12 and a pressurizing mechanism. As the vibrator 12, a piezoelectric material is used.

Title: Wafer conveying vehicle
Inventor: KABATA KAZUO
IPC: H01L21/677
Filed: 1987-11-13
Abstract: PURPOSE:To stop a wafer conveying vehicle when the air around the vehicle contains many dusts and to prevent dusts from adhering to a wafer by employing a dust measuring instrument and a travel controller when the wafer is conveyed by the vehicle. CONSTITUTION:A wafer conveying vehicle 1 travels by carrying a wafer 7 thereon. When the vehicle 1 travels, a dust measuring instrument 2 intakes the air from a suction pipe 3 to measure the dusts in the air, and outputs the measured value of the dusts through an output cable 4 to a travel controller 5. The controller 5 judges whether the dusts of the air in the environment in which the vehicle 1 travels are adhered to the wafer 7 or not from the measured value of the dusts from the instrument 2 to contaminate the wafer 7. If the controller 5 judges that the dusts in the air in the environment in which the vehicle 1 travels are adhered to the wafer 7 to contaminate the wafer 7, the controller 5 generates a control command to a driver 8 through a wafer conveying vehicle travel control cable 6 to stop the vehicle 1, thereby preventing the dusts from adhering to the wafer 7.

IPC: F41B6/00
Filed: 1988-11-14
Abstract: PURPOSE: To ensure quick firing by feeding a large current to a rail and an armature in order to launch a projectile from shooting port, recovering post- launch rail inductive energy and transferring it to a generator. CONSTITUTION: When the rotor 30 of a homopolar generator 22 is driven through a turbine with a launching switch 26 being closed and a specified rotational speed is reached, energy is stored temporarily in an inductor 24. When a launching level is reached, the switch 26 is opened to commutate a current to rails 10, 11 through a conductive armature 40 thus accelerating a projectile and launching it from a shooting port 13. Subsequently, the switch 26 is closed to interrupt storage inductances 24A, 24B from the rail and post-launch rail inductive energy is recovered through a winding 44 interlinking the rails 10, 11 before being returned back to the generator 22 through a cable 50 and a control switching means 52. Consequently, both quick firing and launching at a relatively long interval can be carried out without requiring a large capacitive storage means.
