IPC: A61F15/02
Filed: 1991-04-17
Abstract: PURPOSE:To obtain the ultrasonic cutter of a simple construction which can safely and easily cut a fixing material by providing a cutting edge only at the side face of a cutting blade, and forming the tip of the cutting blade round without providing the cutting edge thereon. CONSTITUTION:The cutting blade 4 is inserted into a deep groove formed at the front end of a horn 7 and is securely fixed by a set screw 14. The cutting blade is replaced when needed. The cutting edge is provided only at the side face 4A of the cutting blade 4. The tip 4B is formed round and has no cutting edge. Then, even if the cutting blade 4 sinks and its tip 4B touches the skin at the time of cutting, the tip does not damage the skin at all and the cutting operation can be smoothly continued without allowing the cutting blade to be entangled with the under winding material applied on the inner side of gypsum. Since the entire part of the cutting blade is exposed, the cutting is easy.

Filed: 1994-04-28
Abstract: PURPOSE:To provide the operation device with excellent responsiveness for the operation by the operator by using a transfer means to transfer a numerical value detected by a tilt detection means to an image generator. CONSTITUTION:When the operator commands turning to the right, for example, since a housing is turned right relatively with respect to a rotor 153 of an angle detector while the rotor 153 is directed in a gravity direction, light receiving sections 157, 159 generate sequentially pulses and a left right phase detector generates a phase signal representing a right rotation (forward rotation) based on the sequence of generation of the pulses, and gives pulses from the light receiving sections 157, 159 to an up-down counter as an addition command signal. The up-down counter executes addition operation for each input pulse to count a count proportional to a turning angle of the housing. When a numerical value of an electric signal in response to a tilt angle of the operation section to the rotor 153 is transferred to an image generator by a transfer means, the image transfer device generates an image signal for displaying a changed image.

Abstract: PROBLEM TO BE SOLVED: To prevent a mixed material from sticking to a vibration board, by attaching a gas cylinder to rolling compaction tamper used for asphalt pavement and equipping a burner in the vibration board to heat the vibration board at a high temperature. SOLUTION: A small gas cylinder 2 is attached to a rolling compaction tamper used for asphalt pavement. A burner is equipped at the upper part of a vibration board 3 and a plurality of suction/exhaust gas inlets/outlets are formed at the side of the vibration board 3. When using the rolling compaction tamper, the burner is ignited at first and after the high temperature of the vibration board 3 has been made sure, the engine is driven to start rolling compaction. Since the paved mixed material gets hot in some extent, it is not necessary to continuously burn the vibration board 3 by the burner and hence the flame of burner is made strong or weak in accordance with the condition or stopped at times. In this way, the mixed material is completely prevented from sticking to the vibration board.  And labors applying oil are not required and the pavement surface is not damaged by dropping oil on the road surface.

Filed: 1993-05-18
Abstract: PURPOSE:To enable a vacuum cleaner to be operated according to procedures set out in a manual by transmitting switch information entered by a user through a hose grip section to a cleaner body via an infrared ray. CONSTITUTION:An operation code is transmitted from the infrared emitting diodes 106 and 107 of a grip section control circuit 101, when an operation switch 127 is pressed, and reaches the infrared receiving photodiode 114 of a cleaner body. A microcomputer 113, then, recognizes that the switch 127 is pressed. Thereafter, the computer 113 stops the operation of an electric blower 116 under operation, or starts the operation thereof when the blower 116 is at rest. Furthermore, the computer 113, upon judging that an up-switch 126 is pressed, holds the state of the blower 116, when the blower 115 is at rest. Also, when the blower 116 is under operation, a rate for reducing a phase time and a judgement frequency are adjusted, thereby increasing input to the blower 116 approximately linearly. When the computer 113 recognizes that a down- switch 125 is pressed, a rate for extending a phase time and a judgement frequency are adjusted, thereby enabling the input to be reduced approximately linearly.
