摘要： In a compass sensor unit, an azimuth data computing method is carried out by the steps of: inputting a signal from a geomagnetic sensor to measure magnetic field; determining whether to store measurement data of the magnetic field based on a distance from the last stored measurement data; calculating an offset value based on the stored data; making a comparison for each component of a plurality of measurement data used for calculating the offset value, and judging the offset value to be valid when a difference between the maximum and minimum values of each component is a given value or more; updating the already stored offset value to the offset value judged to be valid; and correcting newly provided measurement data by the updated offset value to compute azimuth data.

摘要： An ultrasonic transducer is provided at the distal end of a sheath included in an inserting portion of an ultrasonic probe for performing ultrasonic diagnosis. The ultrasonic transducer can transmit and receive ultrasound through an acoustic window 38 facing against the ultrasonic transducer through an acoustic medium filled around the ultrasonic transducer. At least the acoustic window is formed of a resin including a mixture of polyamide block and polyether ester block copolymer resin and polyurethane. Thus, multiple reflection, for example, can be reduced in the vicinity of the acoustic windows. Furthermore, the sheath portion may be formed of the same resin. Thus, the sheath portion can be inserted through an endoscope channel, for example, smoothly with less buckling.

摘要： A ferroelectric memory device according to the present invention includes memory cells. Each memory cell is constructed such that a lower electrode is formed on a silicon substrate, a ferroelectric capacitor having a hysteresis characteristic with at least two non-linear characteristic portions is formed on the lower electrode, and an upper electrode is formed on the ferroelectric capacitor. The memory cells are arranged in a matrix and are provided with a column switching controller and a row switching controller. These controllers are connected via a switching circuit to a write circuit, a read circuit and a detector. When a voltage lower than a coercive voltage is applied to the memory cells, the data storage states of the memory cells are discriminated on the basis of the difference in differential dielectric constants between "1" and "0", thus reading out the data in a non-destructive manner. In the ferroelectric memory device with this structure, an asymmetrical amplitude waveform voltage of a positive voltage lower than a coercive voltage and a negative voltage of an amplitude smaller than the amplitude of the positive voltage is applied to the ferroelectric film on which data is recorded, thereby reading out the data in a non-destructive manner.

摘要： A first ferroelectric capacitor has a ferroelectric member having a film thickness and an area, and electrodes formed on both major surfaces of the member, respectively. Thus, the first ferroelectric capacitor has a polarization. A second ferroelectric capacitor has a ferroelectric member having a film thickness and an area, and electrodes formed on both major surfaces of the member, respectively. Thus, the second ferroelectric capacitor has a polarization. The first and second ferroelectric capacitors are connected parallel to each other, thereby forming a ferroelectric memory device. Since the ferroelectric memory device uses the synthesized hysteresis characteristics of the two ferroelectric capacitors of different coercive field values, it can use multi-value data, and perform nondestructive readout of data stored in the capacitors.
