Title: Detection of slaggy and powdery inclusions in steel by printing
Inventor: TSUCHIYA TAKEHISA
IPC: G01N31/00
Filed: 1981-10-28
Abstract: PURPOSE:To enable quick detection of slaggy and powdery inclusions without using a darkroom or any special device by a method wherein detection paper  impregnated with a color-forming mixed solution containing a derivative of a  chromotropic acid is pressed against the ground surface of a steel material and  then peeled off, and that part of the detection paper which has undergone discoloration is observed. CONSTITUTION:A color-forming mixed solution (containing 5-15% tartaric acid of 0.5-2% hydroxylamine hydrochloride) containing 0.005-0.02% derivative of a chromotropic acid (e.g. chlorophosphonazo III) is infiltrated, for instance, in photographic desilverized printing paper. After part of the solution is removed, the paper is against on the ground surface of a steel material for one minute and then peeled off. When slaggy and powdery inclusions are contained in the steel material, the color of that part of the surface of the peeled detection paper where these inclusions exist is changed into green 1 when chlorophosphonazo III is used, while the color of the other part is blue-violet 2. Thus, the inclusions can be detected quickly and simply.

Title: Waveguide coaxial converter
Inventor: HONMA KAZUO
IPC: H01P5/103
Filed: 1986-07-22
Abstract: PURPOSE: To eliminate the shifting of an insulator due to variation in ambient temperature, vibrations and a shock, an in-use direction, etc., by clamping the insulator by a conductor fixed to a center conductor and fixing it to the center conductor. CONSTITUTION:The conductor 4 is shaped annularly and fixed by being soldered to the center conductor 2b on the upper side of the insulator 3. This conductor 4 positions the center conductor 2b and supports the insulator 3. Further, an antenna part atop the center conductor 2b swells, so the insulator 3 never shifts in position downward owing to vibrations, etc. Consequently, once the passage loss is minimized by impedance adjustment, etc., the insulator 3 does not shift in position owing to variation in ambient temperature, vibrations, a shock, or in-use direction, etc., so the impedance never varies and no increase in passage loss occurs.

IPC: H03L7/12
Filed: 1986-07-25
Abstract: PURPOSE:To reduce the locking time by sweeping a VCO by 1/N only where N is an output frequency of the VCO dividing the locking range. CONSTITUTION:A phase comparator 2 compares the phase of an input carrier 1 whose frequency range is f0+ or - f with the phase of an output wave fv+ or -fr, outputs a voltage corresponding to the phase difference, the DC component is given to a loop filter 3, whose output and an output of a sweep circuit 8 comprising a low frequency oscillator are added and the result is fed to the VCO 5. The VCO 5 outputs a frequency fr in response to the applied frequency fr to a mixer 6. Thus, the locking range from the f0- f to the fo in the range fo+xf is locked by a difference component fv-fr of the output of the mixer 6, and the range from the fo to the fo+ f is locked by the sum component fv+fr of the output of the mixer 6. Thus, the locking time is reduced to a half.
