Title: Fat thickness measuring apparatus
Inventor: TAKEMORI YOSHIO
IPC: G01B17/02
Filed: 1984-02-28
Abstract: PURPOSE:To enable the measurement of the thickness of fat accurately with an extremely simple operation by arranging a plurality of pressure detectors in the perimeter of a measuring probe and bringing the measuring probe to the surface to be measured at the right angle thereto and under a fixed pressure. CONSTITUTION:Pressure-sensitive bars 5 are inserted slidably through three points at an equal angle centered on a probe 1 with an ultrasonic wave transmitter/receiver 3 fixed. When the probe 1 is abutted on the skin, the heads of the pressure-sensitive bars 5 get in contact with the surface of the skin and slid back compressing a spring 8. As a conductor 14 moves simultaneously while plugs 12 and 13 get in contact with the conductor 14, a switch is turned ON. As a specified pressure is applied evenly to the pressure-sensitive bars 5, the tip of the probe 1 sinks into the skin by a certain depth and the center thereof gets vertical to the surface of the skin. Then, switches of the pressure-sensitive bars 5 turned ON simultaneously to operate a starting circuit and the transmitter/receiver 3 emits an ultrasonic wave to the skin. Among the ultrasonic waves incident on the skin, reflected waves alone from the boundary between the fat layer and the muscular layer are selected and measured.

Title: All-purpose working machine
Inventor: FUKUCHI MIKIO
IPC: B24B23/03
Filed: 1984-03-02
Abstract: PURPOSE:To alleviate the fatigue of an operator and as well to aim at enhancing the accuracy and efficiency of working, by providing an actuator for reciprocatingly rotating a pair of long shafts provided at their tip ends with working tools in the direction in which they moves to and away from each other, and as well by providing an operation handle to the long shafts. CONSTITUTION:In order to carry out a derusting process, the operator opens a shut-off valve 11 while holding an operation handle 1 to operate rotary tools 4 so that rotary working parts 4a are driven, and makes them touch on a surface to be ground. Then a shut-off control valve 12 is opened to acruate a cylinder device 7 for reciprocatingly rotating long shafts 3. Accordingly, the rotary working parts 4a performing sector-like motion while moving to and from each other, carry out the derusting process in a wide area without the long shafts 3 being swung to left and right in lage degrees. During this process reaction forces produced upon high rotational speed operation of the working parts 4a are cancelled out with each other since the long shafts are in pair, and therefore, the fatigue of the operator may be alleviated. Further, the long shafts 3 may be held with an optional angle therebetween, and therefore, two fillet weld beads opposed to each other may be derusted at one time by making the distance between both rotary tools 4 coincident with that between the fillet beads.
