Title: Intercom system
Inventor: FUJITA MINORU
IPC: H03G3/32
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of howling in the case of conducting a two-way speech. SOLUTION: A sound quality (pressure versus frequency of sound) characteristic of a signal received from a visitor and picked up by a slave set microphone 10 of an intercom slave set 1 is adjusted via a reception operational amplifier 23 of an interphone master set 2, in a way that the sound volume of the received sound increases as the sound frequency gets higher.  Thus, the user can easily hear a received sound with a high frequency sounded from a receiver 20a of a handset 20, a sound quality (pressure versus frequency of sound) characteristic of a transmission operational amplifier 25 is switched, as soon as that of the reception operational amplifier 23 is switched so as to adjust a sound volume of a transmission sound from a resident and picked up by a master set microphone 20b of the handset 20, in such a way that the sound volume of the transmission sound sounded by a loudspeaker 11 of the intercom slave set 1 decreases as the sound frequency of the transmission signal becomes higher, thereby preventing occurrence of howling in the case of conducting a two-way speech.

Abstract: PURPOSE:To attain low power consumption and high frequency processing by synthesizing an output from an in-phase component modulation mixer with an output from a quadrature component modulation mixer via a resistive 2-terminal circuit network and a capacitive 2-terminal circuit network respectively. CONSTITUTION:The output terminal of a 1st mixer 2 for in-phase component modulation is connected to a modulation wave output terminal 6 via resistive 2-terminal circuit network 4. On the other hand, the output terminal of a 2nd mixer for the quadrature component modulation is connected to a modulation wave output terminal 6 via the capacitive 2-terminal circuit network 5. The outputs from the 1st and 2nd mixers are synthesized via the resistive 2-terminal circuit network and the capacitive 2-terminal circuit network respectively and a modulation wave output is obtained. As a result, even when there is any error in the resistance and the capacitance of circuit components in the resistive 2-terminal circuit network and the capacitive 2-terminal circuit network, the phase difference between the in-phase component and the quadrature component at the modulation wave output is kept to 90 deg. and the process for phase adjustment is not required. Thus, a high speed frequency divider or the like is not required and low power consumption and high frequency processing are attained.

Filed: 1992-09-26
Abstract: PURPOSE:To make the regulation of a shim coil current suitable for an analytical purpose of every kind possible by regulating the shim current so that the noticeable peak of a resonance spectrum becomes the shape suitable for the analytical purpose on the basis of the actually measured value of the noticeable peak. CONSTITUTION:The resonance spectrum data of a sample is collected and four kinds of predetermined index values are calculated with respect to the resonance line indicated from the obtained spectrum data. Next, weighting is applied to the index values to obtain a synthetic evaluation value. Supposing that an objective value is set to the synthetic evaluation value, there are a system confirming whether a calculated evaluation value is within the objective value and a system confirming whether the difference between the current evaluation value and the previous evaluation value is within the objective value on the basis of the magnitude relation with the previous synthetic evaluation value but any evaluation system is arbitrarily used and one evaluation system is selected from a plurality of the evaluation systems. Finally, the control of a shim coil current is performed on the basis of the result of this synthetic evaluation to judge that the shim coil current finally reaches an object and the regulation of the shim coil current is completed.

IPC: G01L1/12
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To prevent adverse effect based on the charge of magnetic permeability associated with from conversion by providing magnetic anisotropy in a helical direction by means of residual stress based on plastic deformation which does not bring an actual macroscopic from change on the surface of a rotary shaft. SOLUTION: The cylindrical shaft 2 having at least ferromagnetic and magnetic distortion areas formed of ferromagnetic and magnetic distortion materials has a pair of peripheral bands, namely, circular bands 6 and 8 detached in a shaft direction and magnetic stress anisotropy in the symmetrical helical direction of the angular direction ±θ of the axes of easy magnetization is given to the bands. When torque is added to the shaft 2, stress anisotropy generated from it is asymmetrically connected with static anisotropy which is intentionally penetrated into the bands and therefore a difference is generated in the responses of the two bands against equal shaft direction magnetized force. Consequently, torque is sensed by using the difference of the shaft direction magnetic permeability of the two bands.
