Title: Delay circuit
Inventor: TERADA KENJI
IPC: H01P9/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To lower the self-resonance frequency of an inductor, to prolong delay time, to increase a use frequency band, and to miniaturize a circuit. SOLUTION: As a distribution constant line for materializing an inductor, a suspended line having structure suspending a core conductor 10 over an air layer 20 via a suspend part 22 is used. Since a capacitance, obtained by serially connecting the capacitance related to the suspend part 22 and the capacitance related to the air layer 20, becomes the ground capacitance of the core conductor 10, the ground capacitance is reduced in comparison with the case of providing no air layer 20, the self-resonance frequency is increased, the inductance is increased, so that the delay time is extended, and the circuit can be easily miniaturized as result of the increased dielectric constant of a dielectric layer 18.

Title: Unit connection structure of unit housing
Inventor: HIRAHARA KAZUHIRO
IPC: E04B1/348
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To inseparably hold respective units by only mounting the upper unit on the lower unit, by providing a male connection member in the upper unit and also providing a female connection member in the lower unit respectively. SOLUTION: When the upper unit U in which an upper connection unit 20 is arranged, is put on the lower unit L in which a lower connection unit 10 is arranged, the front end of a connection pin 28 projected from the lower face of the unit U is positioned to contact the guide of the block body 14 of the unit 10. Then the block body 14 is pushed down against the urging force of a coil spring 17. In this time, since the diameter of block body 14 is freely widened or narrowed, it is expanded. And hence, the front end of the connection pin 28 slides down from the guide and enters into the inside. Since the block body 14 is urged upward by the coil spring 17, it is raised in the hollow space along the rear end of the pin 28. And hence, the block body 14 is contracted to hold the rear end of the pin 28. In this way, the units U, L are can be inseparably connected to each other.
