Abstract: PURPOSE:To open or lock a door without using a key by connecting a lock operation piece to a lock mechanism to enable the operation of a lock piece by operating the lock operation piece. CONSTITUTION:A first contact point 15 and a second contact point 16 are attached to the rear side of a scale (12) of a dial 12 constituting a switch element 14 and the rear side of a scale (0) of a dial 13 respectively, so that both the contact points make contact with each other to deliver a lock command signal when both of the scales are set. And upon receipt of the signal, a joining element 52 is joined to a fixed element 51 so that a locking shaft 41 can be rotated by the rotational operation of a lock operation piece 10 without using a key K. As a result, on the basis of an operation simiar to the case that a locked condition is released by the use of the key K, by inserting a lock piece 45 to the end surface of a lock body 8 from a door body 3, a locked condition can be released and if a reverse operation is conducted under that condition, a door 2 can be put into a locked state with respect to the door body 3.

Title: Torque sensor
Inventor: NORO EIKI
IPC: G01D5/20
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To correct temperature with a simple configuration without requiring a temperature sensor by using a voltage detection means for correcting the temperature of a deviation voltage based on the addition value of each transition response voltage from two reference resistors. SOLUTION: Detection coils 3A and 3B are symmetrically arranged at upper and lower parts in displacement directions X1 and X2 of a core 2. According to displacement, each of inductances L1 and L2 is differentially changed, and a reference resistor RF is connected to each one end of terminals S1 and S2 in series. Each of the other ends is commonly connected to a pulse power supply 4, and the other end of the reference resistor RF is grounded. The electrically equivalent circuits are bridge circuits 5. Transition response voltages VSI and VS2 are generated at the terminals S1 and S2, respectively, and the difference is calculated, thus obtaining a deviation voltage corresponding to the displacement of the core 2.  According to the addition value of the transition response voltages VS1 and VS2 at arbitrary temperature when torque is not applied, a value where a reference addition value at reference temperature is subtracted is multiplied by a constant coefficient as a temperature correction value to correct the temperature.

Title: Forced commutation circuit for thyristor switch
Inventor: KAWABATA TAKAO
IPC: H02M1/06
Filed: 1980-03-24
Abstract: PURPOSE:To perform a commutation reliably by a method wherein a commutator capacitor is discharged and the current drop at the main diode and a commutation reactor is applied as the inverse bias of a thyristor switch. CONSTITUTION:When the thyristor T1 to be used for commutation is turned to an ON position, the charge being charged to the commutation capacitor C1 discharges through a thyristor switch TH1 and a load current IL is eliminated. At this time, as the inductance component in series to the thyristor switch TH1 becomes relatively small, the commutation current IC, which eliminates the load current IL rises to IL quickly, then flows in a sine-wave form through the intermediary of the thyristor T1, the commutation reactor L10 and the diode D1, and at this time, the voltage VC of the commutation capacitor C1 is turned to a cosine-wave form and then inverted, and applied to the thyristor switch TH1, thereby enabling to give an inverse bias between t0 and t2 and to perform a commutation reliably.

Title: Induction device and switching power supply device using the same
Inventor: SAITO MASARU
IPC: H01F27/24
Filed: 1990-02-19
Abstract: PURPOSE:To assure the conversion operations during the low and high loading times by a method wherein the title induction device where a filler scattering the powder of a mild magnetic body in a non-magnetic base material is inserted into a core gap is used as a transformer or a choke. CONSTITUTION:As for the powder of mild magnetic body, mechanically crushed ferrite particles in higher permeability than that of a core 12 material are used while as for the basic material, an epoxy resin is used to scatter said particles in liquid epoxy resin, etc., and then heated and solidified to form a filler 16. During the lower loading time in mild magnetic field using winding current, the higher inductance is given by the powder of mild magnetic body contained in the filler 16. Since said particles are scattered in the filler 16, the magnetic flux will not be concentrated so that the magnetism of the powder of the mild magnetic body may not be lost by the overheating so as to assure the high inductance during the low loading time. On the other hand, when the magnetic field is intensified, the volume of the magnetic body contained in the filler 16 is smaller than that of the core 12 so that the particles of the magnetic body may cause the magnetic saturation however, the non-magnetic basic material contained in the filler 16 offers a firm magnetic resistance not to cause the magnetic saturation up to the marginal operation point during the high loading time.

SOLUTION: At the time of discharging a green compact from the die 10 by pulling down of the die 10, the tooth parts of the green compact are screwed with the helical tooth profile grooves 11 of the die 10 and, therefore, the green compact is extruded while the green compact is rotated along these tooth profile grooves 11. Namely, when a die plate 51 is lowered from the state of (c), the die 10 freely rotatably mounted at the die plate descends while rotating at the lead equal to the lead of the tooth profile grooves 11 of the die while the helical grooves 12 of its lower part are guided by the helices 22 of a punching bench 21. Then, the tooth parts of the green compact are smoothly detached while relatively rotating along the tooth profile grooves 11 and, therefore, the occurrence of the damage of the green compact accompanying the extrusion is averted.
