IPC: H01F7/18
Filed: 1990-05-30
Abstract: PURPOSE: To prevent induction of spurious voltage and power loss at the stationary time of an electromagnetic actuator by turning on a first transistor(Tr) in a transistor Tr bridge on and operating a second Tr in linear mode. CONSTITUTION: The coil 1 of an electromagnetic actuator is connected in series with a resistor 2 and connected with a Tr bridge 3 comprising a combination of Tr 6, 10, 14, 17. The resistor 2 is connected, at the opposite ends thereof, with analog comparators 22. When a reference voltage Vc is fed to an input 25, an error voltage from a subtractor 24 is outputted through an amplifier 27 to a point 28. When the error voltage is positive, the Tr 6, 17 are turned off while the Tr 10 is turned on and the Tr 14 operates in linear mode in proportion to the error voltage. When the error voltage is negative, the Tr 10, 14 are turned off while the Tr 6 is turned on and the Tr 17 operates in linear mode in proportion to the error voltage. When the error voltage is 0, current flowing through the coil 1 goes 0.

Title: Controlling method for roll temperature of continuous annealing furnace
Inventor: NITOU TAKASHI
IPC: C21D1/00
Filed: 1979-10-31
Abstract: PURPOSE:To manufacture annealed steel sheet having good shape and high quality, by making the temp. of steel sheet at a guide roll for the steel sheet approach to the estimated temp. of a roll by heaters for heating roll. CONSTITUTION:The temp. of steel sheet 10 at every positions in the first cooling zone 16 are estimated by the calculation of the rate-controlling factor of a continuous annealing furnace. A heater 62 heats each roll in order to equalize the temp. of steel sheet 10 to the estimated temp., hereby the differences between temp. of the steel sheet 10 and the temp. of each roll is kept very small. The temp. of the roll after heated and the temp. of steel sheet are detected respectively by thermometers, and the difference from the estimated sheet temp. is calculated by a learning unit 54 and is fed to a precessor 44. As a result, the current of the heater 62 is suitably controlled because the difference between the estimated steel sheet temp. by learning control and the actual steel sheet temp. becomes smaller. When the annealing specifications such as the size or the heat pattern of the steel sheet is changed, the roll temp. is changed rapidly, hereby annealing operation is performed in a good yield.

Title: Wavelength conversion element
Inventor: OKAMOTO SOUTA
IPC: G02F1/37
Filed: 1992-06-02
Abstract: PURPOSE:To relieve phase matching conditions by forming an additive layer of the film thickness changing in a waveguide direction on a waveguide and changing the waveguide parameter of the waveguide in a waveguide direction. CONSTITUTION:The waveguide 3 for light is formed across a main surface 2 on an element substrate 1 consisting of a nonlinear optical material. Polarization inversion layers 4 in which spontaneous polarization is inverted along the waveguide direction are formed on the waveguide 3. The additive layer is formed in the upper part of the waveguide 3. The additive layer is formed to the thickness which is smallest at the incident end face 3a of the waveguide 3, increases along the waveguide 3 and is largest at the exit end face 3b. Then, the effective refractive index of the waveguide 3 changes toward the exit end face 3b along the waveguide direction from the incident end face 3a. Namely, the wavelength permissible width at which the second harmonic wave is excited is set wider than the conventional permissible width of the wavelength and, therefore, the phase matching conditions by pseudo transfer matching are satisfied in any region within the waveguide 3 even if the wavelength of the input waves fluctuates more than heretofore.
