Title: Object conveying device with object floating device and conveyance of object
Inventor: HASHIMOTO YOSHIKI
IPC: B06B3/00
Filed: 1993-11-11
Abstract: PURPOSE:To reduce a size and cost in an object conveying device which conveys an object by floating it in the air by mounting a vibrating element and an ultrasonic wave exciting means for exciting it, and forming the vibrating element in such a manner as the thickness of a sound wave generated by the ultrasonic wave exciting may gradually change in a radiation direction. CONSTITUTION:This object conveying device is provided with a vibrating element 1 which is formed into a rectangular plate shape. The vibrating element 1 is fastened onto the tip of a horn 2 in its central area, for example, with screws or the like. The horn 2 is linked with a vibrator 4 which generates ultrasonic vibration as a result of being excited by an oscillator 5, and amplifies vibration generated by the vibrator 4. A plate-shaped sound wave reflection member is disposed along both the sides of a conveying route for an object 7 to be conveyed in such a manner as the thickness (t) of the vibrating element 1 may increase gradually relative to an imaginary horizontal plane 10 along a conveying direction of the object 7. It is thus possible to impact propulsion force to the object 7 in a direction from a thinner part to a thicker part of the vibrating element 1, thereby permitting the object to travel smoothly.

Abstract: PURPOSE:To thin and miniaturize the title motor, by obtaining a superconductive fixed coil, arranged on a base plate. CONSTITUTION:Cooling fluid is sealed into a low-temperature vessel 14 and a superconductive coil 16 on a ceramics plate 15 is brought into superconductive condition. A rotation control signal is inputted from a control circuit 21 into a drive circuit 23 and the phase control of a current, supplied to the superconductive coil 16, is effected by the drive circuit 23. The superconductive coil 16 generates a large field in accordance with the current to give it to a turn table 19.

In this case, when a rotation detecting signal from a rotation sensor 20, attached to a rotary shaft 18, is inputted into the control circuit 21, a control signal is inputted into the drive circuit 23 so that the rotation of the rotary shaft 18 coincides with the reference value 22 of rotation, therefore, the turn table 19 maintains a given rotation. A large rotary field is generated from the superconductive fixed coil 16 in such a manner to turn the turn table 19, therefore, the title motor 11 may be thinned and miniaturized.

Title: Intake device for engine
Inventor: MATSUO NORITAKA
IPC: F02B27/00
Filed: 1993-11-15
Abstract: PURPOSE:To eliminate torque valley (output reduction) at the time of comparatively low speed rotation by branching and opening an air mixture gas in/out branch pipe whose one end is closed, in the vicinity of an intake valve between the throttle valve and the intake valve of the intake passage of an engine, and conserving fluid motion inertia. CONSTITUTION:An intake valve 21 and an exhaust valve 22 are provided on the upper part of a combustion chamber 4 in an engine main body 1, and an intake passage 7 and an exhaust passage 9 are communicated thereto. The intake passage 7 is communicated with the throttle valve 14 of a carburetor 15 through a spacer 13. An air fuel mixture in/out branch pipe 18 is constituted in such a way that a pipe 16 is installed on the spacer 13, and a pipe 17 whose one end is closed is connected to the top end of the pipe 16. In a position where the air-fuel mixture in/out branch pipe 18 is opened to the intake passage 7, its cross sectional area is set to the minimum level, and the cross sectional area of the pipe 17 is set to a level a little larger than that. Since it is possible to make an air column in the branch pipe 18 resonant with some comparatively low speed engine rotating speed, flow motion inertia is conserved by resonance after the intake valve 21 is closed, even if the throttle valve 14 is in a low opening range. It is thus possible to eliminate reduction of engine output at the time of comparatively low speed rotation.
