Patent JP-H0837791-A (JP)
Title: Control circuit for three-phase reluctance motor
Inventor: BAN ITSUKI
IPC: H02P6/10
Filed: 1994-07-25
Abstract: PURPOSE:To obtain a control circuit by which a high-speed rotation can be performed by a method wherein, when an armature coil ia de-energized, its magnetic energy is stored in a capacitor, the high voltage of the capacitor is utilized and an armature coil to be next energized rises quickly. CONSTITUTION:When energization is stopped, magnetic energy in an armature coil 39a is carried to a capacitor 47a via diodes 21b, 21a since it is prevented from returning to DC power supply by a reverse blocking diode 49a-1, and thus a high voltage is generated. Consequently, since the magnetic energy is extinguished quickly and a current is dropped quickly, it is possible to prevent an countertorque from being generated. When transistors 20a, 20b are set conductive and the armature coil 39a is energized, an applied voltage becomes the sum of a charging voltage for the capacitor 47a and of a power supply voltage. As a result, the armature coil voltage 39a rises quickly. Thereby, the generation of a reduced torgue is eliminated. In addition, since the coil is energized substantially with square waves, an output torque is increased.

Title: Sampling probe flow sensor
Inventor: CHIMOSHII AARU FUEIBAA
IPC: G01F1/684
Filed: 1989-08-04
Abstract: PURPOSE:To protect a sensor from contaminant in fluid by constituting the above sensor from both a housing which has a region having maximum diameter in the specified position and a region having small diameter in the downstream side apart therefrom and a flow sensor element. CONSTITUTION:A main body 10 and a member 11 are together equipped with a passage described hereunder in a hole 12. This passage has a minimum cross-sectional area in a region 21 having a maximum diameter in the main body 10. The effective cross-sectional area of this passage is increased in the downstream side. Maximum flow velocity and minimum pressure are obtained in a port 24 owing to Bernoulli's effect. Further flow velocity is lowered and pressure is raised in a port 25. Flow is introduced into the port 25 reversely to the direction of flow passing through the hole 12 as shown in the arrows 34-36 by this pressure difference. Then this flow passes through a channel 26 and is discharged from the port 24. Therein the pressure difference of the parts 24, 25, namely flow velocity and flow rate of flow passing through the channel 26 are proportional to the flow rate of fluid passing through the main body 10. Therefore a sensor element in the channel 26 generates output showing flow rate passing through the hole 12. Further great particles which impart damage to a detector are inhibited from being introduced into the port 25.

Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide an electromagnetic heating cooker which prevents heating nonuniformity from occurring, by providing a device for supporting and driving a heating coil so that the center of the heating coil moves on a revolution track around the center under a supporting part of a heated pan. SOLUTION: When a motor M is turned ON, a heating coil 3 rotates along a circumference track of which center is output shaft M1 at central downward of a spherical concave and radial is length of an arm 7. At the same time, an electromagnetic unit 8 becomes in operating condition. Therefore, induced current of the heating coil 3 connected with the electromagnetic unit 8 occurs at bottom of a heated container 6 to generate heating condition.  Then, at the inner periphery, the intermediate part, and the outer periphery of the heating coil 3, respective number of magnetic flux interlinkages may be different each other, but even at this case, revolution of the heating coil 3 eliminates heating nonuniformity caused by variation of strength of the induced current In addition, a supporting shaft 71 and a central cylinder 4 as a supporting body can rotate relatively, and therefore torsion of a lead L is avoided.

IPC: H03H15/00
Filed: 1982-11-19
Abstract: PURPOSE:To shorten a convergence time by varying the tap weight coefficient of a digital transversal automatic equalizer according to the state of a line. CONSTITUTION:A signal to be equalized is applied from an input terminal. The signal is A/D-converted 1, delayed 2, and multiplied by tap coefficients, and results are integrated over the entire delay line and discriminated by a discriminator 5 to obtain a digital output. Taps are adjusted by inputting the A/D- converted signal and the error signal err which is the difference between the input and output of the discriminator 5 to a correlator 6. The correlator 6 calculates correlations of respective taps, which are averaged by an integrator 7 to obtain a tap adjustment signal. The adjustment radio based upon this tap adjustment signal is increased when an out-of-synchronism and an error rate are large to speed up the pull-in of the equalizer.
