Filed: 1988-06-16
Abstract: PURPOSE:To make it possible to obtain the most excellent defect detecting capability at remote and close flaw detecting distances each, by making the width of a first piezoelectric transducer large, and making the width of an nth piezoelectric transducer small. CONSTITUTION:When a flaw in a body under test 6 is detected with an array type probe 5 at a slant angle, the sum of a distance W1 between the probe 5 and the body under test 6 and the propagating distance W2 of an ultrasonic wave in the body under test 6 is considerably larger than the sum of the distance W3 between the probe 5 and the body under test 6 and the propagating distance W4 of the ultrasonic wave in the body under test 6. In the aligning direction from a piezoelectric transducer 1-1 to a piezoelectric transducer 1-n in the probe 5, a width d1 is changed into a width dn in an arithmetic series pattern. At the same time, in the longitudinal direction of the piezoelectric transducer, a length L1 which is approximate to a width D1 of the piezoelectric transducer in the first group is linearly changed into a length Ln which is approximate to a width Dn of the piezoelectric transducer in the Nth group. The sizes of an electrode 3 described above are provided. Therefore, the scanning of an ultrasonic wave beam and the change in beam patterns can be performed at the same time only by shifting the positions of transmission and reception without changing the combination number from the piezoelectric transducer 1-1 to the piezoelectric transducer 1-n along the piezoelectric transducer D1 to the piezoelectric transducer Dn.

Filed: 1982-08-27
Abstract: PURPOSE:To improve the accuracy of calculation of an absolute speed of a target when own vessel makes a turning movement, by calculating a sideslip speed of own vessel by using the factor of shift of the course of own vessel. CONSTITUTION:A target observation device 1 measures a distance, azimuth and elevation to a target, and delivers the results to a relative speed calculating device 7. In this device, an information on the position of the target based on polar coordinates is converted into a positional information based on orthogonal coordinates using own vessel F as the origin, and then differentiated, whereby the relative speed of the target is calculated. The course A of own vessel measured by an own vessel course measurer 3 is differentiated by an own vessel course shift factor calculating device 4, and the shift factor of the course of own vessel thus calculated is multiplied by a parameter determined for each vessel. Thereby a sideslip speed C is calculated in a sldeslip speed calculating device 5. In an own vessel speed calculating device 6, the speed of own vessel resolved into the same system of orthogonal coordinates as used in the relative speed calculating device 7 is calculated from the heating speed B of own vessel measured by own vessel heading speed measurer 2, the sideslip speed C calculated by the sideslip speed calculating device 5 and the course A of own vessel measured by the own vessel course measurer 3.

Title: Semiconductor pressure sensor
Inventor: KOIKE YASUHIRO
IPC: G01L9/04
Filed: 1989-06-12
Abstract: PURPOSE:To make it possible to use a sensor under high pressure by using one surface of a semiconductor element as a pressure receiving surface on which external pressure is applied, providing a pressure sensitive element on the rear surface of the element, bonding a supporting member having a through hole to the rear surface of the semiconductor element, and taking out the output of the pressure sensitive element by way of the through hole. CONSTITUTION:Two diaphragms 22 are formed on a lower surface 21a of a semiconductor pressure sensitive element 21. Strain gages 23 are formed on a region 21b which is held with the diaphragms 22. Said semiconductor pressure sensitive element 21 is bonded to a stage 25 having a through hole 25a. When external pressure is applied on an upper surface 21c of the semiconductor pressure sensitive element 21, the semiconductor pressure sensitive element 21 receives strain. The strain causes the change in resistance value of each strain gage 23. At this time, the pressure (a) which is applied on the pressure receiving surface 21c of the semiconductor pressure sensitive element 21 acts on the bonding surface of the stage 25 as the stress in the compressing direction. The stress in the direction for peeling the bonding surface does not act on. Therefore, this sensor can be used even under high pressure.

Title: High speed transmission connector
Inventor: NAGASE KAZUHISA
IPC: H01R13/658
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To constitute a pseudo coaxial in all parts within a connector, and improve high frequency characteristic more by forming a ground terminal so that the circumference of one signal terminal is surrounded by four ground terminals. SOLUTION: Between both printed circuit boards to be connected by a male connector and a female connector, terminals 4 and 3 are arranged so as to surround an optional signal terminal 4 which four ground terminals 3 around it.

IPC: B29C65/56
Filed: 1986-06-27
Abstract: PURPOSE:To obtain a fast-heating resin processing heater, which can directly contact with resin to be processed and has a long service life and eliminate the need of an extra means for cooling and solidifying the resin by a structure wherein electrically-conductive ceramic excellent in high-temperature durability such as oxidation resistance, corrosion resistance or the like and high-temperature strength is employed. CONSTITUTION:A high-temperature member consisting of electrically-conductive ceramic 11, which is produced by mixing and sintering high resistance ceramic and low resistance ceramic, is brought into direct contact with resin or material to be processed under the state that the heat is generated in the member by energizing. Silicon carbide, aluminum oxide or the like, which is excellent in high-temperature durability, is employed as the high resistance ceramic component. Highly heat resistant high melting point compound such as zirconium boride, titanium boride, hafnium boride or tantalum boride is employed as the low resistance ceramic component. Accordingly, because the resin is directly heated by the high temperature member, the title heater is excellent in fast-heating. In addition, almost no change in the characteristics of the heater occurs after repeated use and consequently the service life of the heater is long. The integration of the electrically-conductive ceramic 11 with insulating ceramic 12 is preferable for increasing the strength of the heater as the structure for forming circuitry demands.
