Title: Electrostatic capacity type humidity sensor
Inventor: UEKI TOYOAKI
IPC: G01N27/22
Filed: 1987-02-07
Abstract: PURPOSE:To widen the range of impressed voltage and to prevent deterioration of a titled sensor even if a DC voltage is inadvertently impressed thereto for a long period of time by providing a gap part, etc., communicated with the outdoor air between a lower electrode and porous ceramic element formed with an upper electrode on the opposite side thereof. CONSTITUTION:The lower electrode 3, an upper electrode leading out part 4, a glass insulating and supporting layer 5, the upper electrode 6, the porous ceramic element 7 and the gap part 8, etc., are provided on an alumina substrate 1. Since the gap part 8 communicated with the outdoor air is provided on the electrode 3 and the element 7 formed with the electrode 6 on the opposite side, water molecules exist more in the gap part 8 to increase the electrostatic capacity between the electrodes when the moisture increases. Namely, the dielectric constant increases and the electric resistance of the element 7 decreases with an increase in the amt. of the water molecules and, therefore, the similar effect of a substantial decrease in the inter-electrode distance is obtd. and the electrostatic capacity increases. The range of the impressed voltage is consequently widened and the deterioration of the sensor is prevented even if the DC voltage is inadvertently impressed thereto for a long period of time.

Title: Demodulation circuit
Inventor: GOTO TOSHIHIRO
IPC: H03M1/12
Filed: 1991-01-29
Abstract: PURPOSE:To execute high-precision demodulation without using any low-pass filter which generates waveform distortion. CONSTITUTION:When an amplitude modulated signal is inputted to a double wave rectifier circuit 1, the double wave rectifier circuit 1 executes the double wave rectification of the amplitude modulated signal, and a rectified amplitude modulated signal is inputted to a monostable multivibrator circuit 2 and an A/D conversion circuit 3. After the double wave rectification, the monostable multivibrator circuit 2 is triggered based on the amplitude modulated signal and at such a time, however, since the output pulse keeping time of the monostable multivibrator circuit 2 is much shorter than the 1/2 cycle of a carrier, the output pulse of the monostable multivibrator circuit 2 becomes a clock signal having the double frequency of the carrier. The A/D conversion circuit 3 executes the sample/hold of the rectified amplitude modulated signal near the peak voltage, converts the said voltage to a digital value and outputs it.

Title: Through-type current transformer
Inventor: NOZAKI ASAJI
IPC: H01F38/28
Filed: 1984-02-20
Abstract: PURPOSE:To prevent the deterioration of error characteristics in a rated current region even on small rated primary currents by adopting a ring core constituted by combining cores of two kinds having different permeability in severally required sectional area. CONSTITUTION:A ring core 1 is formed by laminating cores of two kinds having different permeability in the annular radial direction, a core having magnetization characteristics shown in a curve (b) and high permeability mu1 is used as a section S1, and a core made of an silicon steel plate (permeability mu2) having magnetization characteristics shown in a curve (a) and high saturation flux density is adopted as a section S2. According to such constitution, most of magnetic flux PHI in the ring core 1 pass in the core S1 because of mu1>>mu2 in a rated current region, and exciting currents are reduced, thus obtaining excellent error characteristics. When overcurrents flow through a primary conductor 3, permeability mu1 is reduce while the core S1 is saturated, but magnetic flux PHI in the ring core 1 moves to the core S2 side in an overcurrent region because the saturation flux density of the core S2 is high and permeability mu2 is made larger than mu1, and the characteristics of the overcurrent region can also be satisfied.

Abstract: PURPOSE:To facilitate manufacturing and to prevent variance in gap dimension from being generated by arranging a magnetic film with high saturation magnetic flux density coming in contact with an I core, a magnetic film with low saturation magnetic flux density, and a gap film at the tips of the I core and a U core in sequence stated above. CONSTITUTION:An I type compound core structure body 10 is generated by filming the magnetic film 3 with high saturation magnetic flux density on an I core 2, and filming the magnetic film 4 with low saturation magnetic flux density on the film 3, and furthermore, filming the gap film 5 on the film 4. And after the I type compound core structure body 10 is generated, it is joined integrally with the U core with glass 6 as joining substance, and after that, post-working is executed on a sliding plane where a gap is exposed, etc. Therefore, it is not required to perform a filming process at a U core 1 side at all. In such a way, a manufacturing process can be simplified, and it is enough to form the gap film 5 only at an I core 2 side, which reduces probability to generate the dispersion.
