    摘要： Materials having different compositions are arranged to prepare a molded form in which the sound velocity characteristic is varied from high frequency to low frequency from the center toward the periphery. An ultrasonic wave-radiating face of the molded form and the back face of the ultrasonic wave-radiating face are arranged in parallel to each other to prepare a transducer in which the center region can transmit/receive high-frequency ultrasonic waves and the periphery region can transmit/receive low-frequency ultrasonic waves.

    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： An upper electrode of a capacitor has a two-layer structure of first and second upper electrodes. A gate electrode of a MOS field effect transistor and a fuse are formed by patterning conductive layers used to form the lower electrode, first upper electrode and second upper electrode of the capacitor. In forming a capacitor and a fuse on a semiconductor substrate by a conventional method, at least three etching masks are selectively used to pattern respective layers to form the capacitor and fuse before wiring connection. The number of etching masks can be reduced in manufacturing a semiconductor device having capacitors, fuses and MOS field effect transistors so that the number of processes can be reduced and it becomes easy to improve the productivity and reduce the manufacture cost.

    摘要： An identification mark constituted of irregularities is formed on the surface of a wafer, which is sealed with a resin layer and a dicing tape may be adhered to the backside. Multiple infrared units irradiate infrared rays towards the surface of the wafer from the backside thereof, wherein they transmit through the wafer and are then reflected at the interface between the resin layer and the surface of the wafer, thus producing reflected rays. An image pickup device picks up an image of the interface including the identification mark based on reflected rays. Optical axes of the infrared units extend to cross the surface of the wafer in different directions; hence, the image pickup device receives only a part of reflected rays, which are reflected at the interface in a prescribed direction. A polarizer can be arranged in proximity to the infrared unit or the image pickup device.

    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： With regard to the geomagnetic sensor 1, the control logic circuit 11 conducts control of the geomagnetic sensor 1. When the geomagnetic sensor 1 is installed in a cell phone device, the control logic circuit 11 reads the measurement values pertaining to the ambient magnetic field from the geomagnetic sensor circuit 12, obtains the offset value from the pertinent measurement values, and stores it in the fuse memory 13. At times of measurement by the geomagnetic sensor 1, the control logic circuit 11 reads the offset value from the fuse memory 13, and corrects the measurement values of the geomagnetic sensor 12 using the pertinent value. With regard to the temperature sensor 201, the control logic circuit 211 conducts control of the temperature sensor 201. During preparation of the temperature sensor 201, the control logic circuit 211 reads the result of measurement of the property pertaining to the ambient temperature from the temperature sensor circuit 212, obtains the initial value and correction value from the result, and stores the pertinent values in the fuse memory 213. At times of operation of the temperature sensor 201, the control logic circuit 211 reads the initial value and correction value from the fuse memory 213, and corrects the measurement values of the temperature sensor circuit 212 using the pertinent values. The correction coefficients a11-a22 of the magnetic sensors are measured during LSI shipment inspection. The correction data D1-D4 obtained from these correction coefficients a11-a22 are written into the fuse memory 315. The control circuit 308 inputs the detection outputs Sx and Sy of the magnetic sensors 310 and 311 to the internal register during geomagnetism detection. The correction data D1-D4 is read from the fuse memory 315. Detection outputs Sx and Sy are corrected using formulas (309) to (312).
