Title: Transponder, element and transponder
Inventor: HATTORI YASUSHI
IPC: G01S13/76
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To provide the transponder element and transponder which eliminate the consumption of a storage battery except when a transponder signal is transmitted. SOLUTION: The transponder element 11A operates with the electric energy obtained from a receive electromagnetic wave except when an interrogation signal is received and when the transponder signal for decoding is transmitted and operates with the electric power supplied from the storage battery 13 when the transponder signal is sent by turning on an FET 243. Thus, the transponder signal is sent by receiving the electric power from the storage battery 13 only when the transponder signal is sent, so the consumption of the storage battery 13 is reducible. Further, the transmission output of the transponder signal can be increased as compared with a case wherein the element is driven only with the energy of the receive electromagnetic wave without using the storage battery 13, so the communication distance can be increased.

Abstract: PROBLEM TO BE SOLVED: To cope with the soldered surface, in the spite of its being located on the back side or the surface side by forming in a cylinder in which a contact part is installed on the inside, a small diameter part is formed at one end and a large diameter part having a flange is formed at the other end, and a level difference part is formed between them. SOLUTION: A small diameter part 15 is formed at one end of a connecting member 14, a large diameter part having a flange 16 formed at the other end. Four curved contact parts having elasticity are formed on the inside. The connecting member 14 is passed through the through-hole of a circuit board 3 and inserted until a level difference part comes in contact with the surrounding of the through-hole, and soldering is conducted from the back side or the surface side. Since the small diameter part 15 is closed, solder does not enter the connecting member 14. Since the flange part 16 side is closed with a thin elastic member 20 such as silicone rubber, penetration of solder caused by the scattering of the solder is prevented.  By installing a projection in a fixing component itself to the circuit board 3, fixing height is made constant, independently of the back side or surface side of the circuit board.

Abstract: PURPOSE:To judge a result of the inspection of the internal structure of a concrete building with a high reliability by setting a reference surface in a concrete main body of a concrete test piece. CONSTITUTION:At least one reference surface 111 is set in a concrete main body 11 of a concrete test piece 1. Inside of the main body 11 is perfectly filled with concrete. An object 12 to be detected is formed of two reinforcements 121, 122. Sensors 21, 22 (ultrasonic sensor or the like) detect the position of the object 12 viewed from the reference surface. The data related to the physical quantity such as depth W1, W2 and diameters d1, d2 of the reinforcements 121, 122 and a space D1 between them viewed from the reference surface is thereby obtained. Since the physical quantity of the reinforcements 121, 122 is obtained on the basis of the manufacturing condition of the test piece 1, a reference data can be obtained. This reference data is compared with the data, which is obtained by practically breaking a concrete building for inspection, so as to judge that an embedded object to be detected satisfies the requirements or not.
