Title: Optical fiber for detecting liquid
Inventor: YOSHINO TOSHIHIKO
IPC: G01V8/16
Filed: 1983-04-01
Abstract: PURPOSE:To obtain a liquid detecting optical fiber which is short in response time, capable of maintaining a high sensitivity detection in a wide temperature range, and also long in working distance by devising the thickness of a clad layer of a single mode type optical fiber. CONSTITUTION:A single mode type optical fiber 3 for detecting liquid is constituted of a quartz core 1 and a quartz clad 2. The thickness of the clad 2 is 6lambda<=T<=20lambda when it is shown by a wavelength lambda of a light emitting element. In this way, the thickness of the clad 2 is set within a range of an inequality. When the thickness of the clad 2 is prescribed in accordance with the wavelength lambda and also so as to be somewhat thin, the optical fiber 3 is apt to be influenced by the outside. Therefore, when a liquid to be detected adheres to the optical fiber 3, leakage of a light to the outside becomes large remarkably. That is to say, a liquid can be detected with high sensitivity.

Title: Circular waveguide line
Inventor: ITOU YOSHIHARU
IPC: H01Q21/00
Filed: 1984-03-24
Abstract: PURPOSE:To obtain a circular waveguide line where a signal is matched sufficiently between a feeding part and a waveguide space by providing a conical matching body while its apex is directed to the aperture in the waveguide space. CONSTITUTION:A couple of metallic disks 1, 2 are provided so as to be opposed with mutual parting, and plural slots (or slits) 1a as power radiation aperture are formed to the metallic disk 1 concentrically or in spiral. On the other hand, the metal-made matching body 5 of conical shape having a taper face of theta ( 45 deg.) is provided in the waveguide space S while its apex is directed to the aperture 2a. The bottom part of the matching body 5 is fitted to the metallic disk 1 coaxially and then the apex of the matching body 5 exists on the center axis of the aperture 2a.

Title: Detection system for sent-back tone signal
Inventor: CHIYOUNO TATSUO
IPC: H04B17/30
Filed: 1981-04-17
Abstract: PURPOSE:To monitor whether a circuit is normal or not by transmitting a monitoring tone singal from the base station of a car telephone system, sending it back to the base station from a mobile station having received the tone singal, and detecting whether the signal is received or not and whether the transmission and reception frequencies are coincident with each other by the base station. CONSTITUTION:The frequency of a clock signal from an oscillator 1 is divided by four and the resulting signal is transmitted as a monitoring signal from a terminal S. A comparison signal generator 3 which inputs the clock signal from the oscillator 1 generates a comparison signal REF having the same frequency with the transmitted signal and supplies it to a comparing circuit 4, but the phase of this REF is adjusted by the comparison signal generating circuit 3 on the basis of the comparison result of the comparing circuit 4. Namely, every time a received signal R does not rises during the low-level period of the REF, a one-clock removal signal is generated to delay the phase of the REF by one clock each. When their signals are in phase with each other for a long period, a monostable multivibrator generates an output, so that the sending-back of the tone signal is discriminated.
