Title: Flaw detecting element for eddy current flaw detection device
Inventor: ARAKI YASUO
IPC: G01N27/90
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To easily detect the direction of a detect being present in a metal to-be-tested and obtain much information on the defect for accurately repairing and drastically reducing period. SOLUTION: In a flaw detecting element, two square coils 2 and 3 which cross at right angle are provided inside an excitation coil 103. By constituting the flaw detecting element as in the above, eddy current in the metal to-be-tested 110 is generated concentrically with the excitation coil 103 and the influence of eddy current which changes depending on the direction of defect can occur only in either detection coil 2 or 3 determined by the direction of defect. Therefore, by configuring two detection coils so that each outputs the difference each other, the direction where a signal is generated becomes opposite to the direction of defect, thus judging the direction of defect from that (polarity) of the detected signal.

This cell is cooled down to room temp. at a prescribed rate after the injection. The monomer is polymerized by irradiating the monomer with light, such as UV rays, at the temp. at which the liquid crystal compsn. exhibits a smectic phase in this stage. The mixture in the cell is heated again up to the temp. at which the liquid crystal compsn. exhibits a phase on the higher temp. side than the smectic phase after the formation of the monomer. The cell is thereafter cooled down to room temp. at the prescribed rate.  The restrainings of the polymer by the interaction between the polymer and oriented films 7, 8 and between the polymer and the liquid crystal molecules, respectively, are released by executing such stages.

Title: Coil bobbin for indicating instrument
Inventor: OIKE YUKIO
IPC: G01R5/16
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To enhance the productivity by providing protrusions and recesses for preventing slippage of conductor at least partially in the outer surface of casing and preventing slippage of the conductor at the initial stage of winding thereby preventing breakage of the conductor due to removal from a coil bobbin. SOLUTION: Winding protrusions 2C function to prevent a conductor from slipping in the direction perpendicular to (lateral direction on the drawing) the winding direction of conductor (vertical direction on the drawing). Since the winding protrusions 2C are provided on the side face of a second coil bobbin body 2A, the conductor does not slip at the start of winding even if a coil bobbin body having substantially disc-like shape is employed in order to increase the number of turns per the volume of apparatus. Since high tension is not applied to the conductor at the time of winding, the conductor is protected against breakage.

Title: Vibration isolator
Inventor: NAKAJIMA ZENJI
IPC: H02M3/335
Filed: 1990-11-30
Abstract: PURPOSE:To damp a large vibration out of a vibro-source by interposing a vibration isolator made up of an actuator generating a mechanical vibration and a widening mechanism for this amplitude, between at least two adjacent cylinders set up in a bush. CONSTITUTION:The same phase electric signal is inputted into each of actuators 62, 63, 64 and these actuators expand or contract with the same phase. When the first actuator 62 is expanded by input of the electric signal, a first flat piston 67 shifts downward, transferring some pressure to a liquid in a first liquid chamber 72, and a first T-shaped piston 68 is largely shifted, thereby pushing up the second actuator 63. In this case, this second actuator 63 itself also receives the electric signal input and expands to some extent. With this action repeated, an output piston 75 moves so largely. In brief, there is formed a widening mechanism 76 widening the amplitude of mechanical vibrations in these three actuators 62, 63, 64 connected in series. With this constitution, a large vibration in an engine can be neutralized by a counter vibration of a vibration isolator 60.
