Title: Magnetostriction actuator
Inventor: KATAYAMA HIROSHI
IPC: H02N2/00
Filed: 1993-01-26
Abstract: PURPOSE:To provide a magnetostriction actuator in which a large displacement is obtained even by a weak magnetic field. CONSTITUTION:Displacement generating means 12 formed of a plurality of laminated layer films of a magnetostrictive film 14 and a non-magnetostrictive film 15 are laminated is displaced by a control magnetic field of magnetic field generating means 13. Thus, a bending deformation of a composite layer film having much larger than a displacement by magnetostrictions of the individual films 14, 15 occurs based on the difference in magnetostriction between the films 14, 15, and obtained as a ending deformation output of the means 12. Since the composite film is formed by laminating film members, material and structure strengths are improved, permeability is improved, the bending deformation occurs even by a small applying magnetic field to sensitively cope with a variation in the magnetic field. As a result, a large displacement is obtained even by a small-sized and weak magnetic field, and the means 12 can be remotely controlled by the means 13 disposed separately from the means 12.

Title: Private display unit with protection circuit
Inventor: KAWAGUCHI MASAYOSHI
IPC: G05F1/10
Filed: 1990-01-20
Abstract: PURPOSE:To prevent the destruction of a private display unit and HTU even if a DC power line is erroneously connected to the private display unit by providing an inverse voltage prevention circuit which receives a DC power output from a demander terminal unit (HTU) and prohibits conduction when the positive/negative polarities of the received DC power output are inverse. CONSTITUTION:The inverse voltage prevention circuit 14 is provided on the power input-side of the private display unit with protection circuit 7. When the DC Power source whose positive/negative polarities are inverse is connected to the inverse voltage prevention circuit 14 and the voltage in the inverse direc tion is impressed owing to the erroneous wiring of a worker, an inverse direc tion voltage is impressed on the diode 19 of the inverse voltage prevention circuit 14. Thus, a relay 20 is not exited and a contact 21 holds an open state. Consequently, the DC power output in the inverse direction form an HTU power source part 11 is prevented from being supplied to a power source part 15. Thus, the private display unit with protection circuit 7 and HTU 3 are prevented from being damaged even if the DC power lines 8a and 8b are erroneously connected to the private display unit with protection circuit 7.

Title: Battery pack
Inventor: HIRATA MASARU
IPC: G01R19/165
Filed: 1994-02-02
Abstract: PURPOSE:To break a current path immediately when a short circuit occurs between terminals so as to prevent overcurrent from flowing by providing a short-circuit detecting circuit and a switch circuit having an analog switch. CONSTITUTION:A short-circuit detecting circuit 5 is connected in series with potential at each end of a battery 2 and has two high-value resistors (r1) and (r2) that divide the potential at each end and a low-value resistor (r3) inserted into an electrical path between the battery 2 and terminals 3, 4. The comparator 13 of the circuit 5 receives the input of a dropped voltage made to appear at each end of the resistor (r3) by a current passing through the resistor and the input of a divided voltage appearing at the point of connection between the resistors (r1), (r2), and transmits a detection output when the dropped voltage exceeds the divided voltage. An analog switch 15 in a switch circuit 6 breaks the circuit in response to the detection output and, after the detection output has disappeared, automatically restores itself. Therefore, the connection between the battery 2 and the terminals 3, 4 is broken in the event of a short circuit, thus avoiding accidents and enhancing safety.

Title: Analytical method of moisture
Inventor: HAMADA HIROBUMI
IPC: G01N30/96
Filed: 1980-02-02
Abstract: PURPOSE:To enable ions to be analyzed continuously by beforehand removing org. matter prior to supplying the sample of an aqueous soln. to be analyzed to an ion- exchange chromatograph analyzer. CONSTITUTION:A liquid feed pump 3 is driven to supply a sample 1 into an adsorption tower 4. While the sample 1 flows among the resin 6 in the tower 4, only the org. matter contained in the sample 1 is adsorbed and removed by the resins 6. The sample 1 which does not contain org. matter is conducted from the tower 4 to an ion-exchange chromatograph analyzer 5, by which the ions in the sample 1 are analyzed. For example, a styrene-divinylbenzene copolymer is used for the resins 6. Since no org. matter enters the analyzer 5 in this way, the sticking of org. matter in the analyzing column of the analyzer 5 does not occur and the deterioration of the analyzing column is prevented.

Title: Controller for looper of rolling mill
Inventor: OKABE HISAO
IPC: B21B37/50
Filed: 1980-02-06
Abstract: PURPOSE:To make a looper smoothly descend to the stand-by position after the tail end of strip runs out of the rolling stand, by monitoring the variation of looper angle from the practical value when the tail end of strip approaches the first stand, and by changing over the looper from the electric current control to the position control when the foregoing variation exceeds a constant value. CONSTITUTION:The detector 25 detects the moment t1 at which the tail end of strip 3 passes over a point Pi in front of the i-th stand 1; the comparator 24 receives the rising angle theta of looper, and makes up its own reference value by adding a constant value alpha to said angle theta. Meanwhile, if the time, at which the tail end of strip 3 runs out of the i-th stand 1, is designated as t0, the value of alpha is set to a value a little larger than the value of slight variation caused by a tension control effected at ti<t<t0. When the tail end of strip 3 runs out of the stand 1, the strip 3 is released from tension between the i-th stand 1 and the (i+1)th stand 2; thereby, the looper tends to quickly rise up. However, the comparator 24 produces a signal theta>=theta1, and the change-over switch 26 changes over the constant electric current control to the position control system 20 comprising the position controller 21 and the voltage controller 22, stops the rise of looper, and returns the looper to the stand-by position.
