Title: Double conversion type transmitter receiver
Inventor: KITATSUME SUSUMU
IPC: H04B1/40
Filed: 1981-06-16
Abstract: PURPOSE:To improve the frequency stability and to arbitrarily select the frequency of an oscillator, by arranging a plurality of quartz osciallators which control local oscillating circuits for a down-converter and an up-converter respectively at the same temperature. CONSTITUTION:A quartz oscillator 8 includes sub-quartz oscillators f1 and f2 respectively for reception and transmission, and the oscillators f1 and f2 are located under the same environment. Reception and transmission local oscillators 3 and 4 receive required local oscillating frequencies fL1 and fL2 from the oscillators f1 and f2 respectively and provide them to reception and transmission frequency converters 5 and 6 respectively. Through the constitution like this, the frequency stability almost the same degree as the system of a common master oscillator control can be attained. Further, no frequency limit as the use of the master oscillation is imposed, allowing to set arbitrary frequencies.

Title: Weak point pin failure detector
Inventor: HITOMI ICHIROU
IPC: G01M13/00
Filed: 1978-07-31
Abstract: PURPOSE: To surely detect the instantaneous breakage and the progression of fatigue  failure of a weak point pin by providing a hole in the weak point pin and sealing a pressure gas therein.  
     CONSTITUTION: A hollow pressure sealing hole 4 is provided across the weak point part 3' of a weak point pin 3 and a pressur detecting element 5 is disposed at one end thereof. Then, when a gas of a specified pressure is sealed in the pressure sealing hole 4 through a gas filling hole 6, the sealing gas gradually leaks through fatigue failure part A as the weak point 3' through fatigue and the fatigue failure face reaches the pressure gas sealing hole 4. Hence, by detecting the decreasing condition of the sealed gas pressure via the pressure detecting element 5, the progression of the fatigue failure is detected. On the other hand, when an abnormal pressure is exerted upon links 1,2 and the weak point part 3' breaks instantaneously, the sealed gas pressure sharply drops and the instantaneous breakage is detected

For example, a pair of baffle plates 5, 5' are disposed on both side parts of the strip S, and these are made respectively movable in the width directions by means of cylinders 6, 6' which are disposed horizontally on the outside of the side walls of the cooling zone. The unit 7 controls the cylinders 6, 6' automatically according to the signal from the sensor 4, and adjusts the spacing between the plates 5, 5' and the side surfaces of the chambers 1b, 1b. The lateral ratios of the flow rates of the gases escaping in both right and left width directions after collision against the strip S are controlled by this and the advance direction of the strip S is corrected.
