Title: Manufacture of ultra-low-molecular weight polyvinyl alcohol
Inventor: OISHI TSUKASA
IPC: C08F8/12
Filed: 1987-05-09
Abstract: PURPOSE:To produce an ultra-low-molecular weight PVA having a uniform molecular weight distribution with industrial advantage, by polymerizing a vinyl acetate monomer in a solvent having a chain transfer constant Cs in a specified range with the monomer charged successively, and saponifying the resulting PVAc. CONSTITUTION:In a process of polymerizing a vinyl acetate monomer in a solvent of which chain transfer constants Cs is 2X10<-4>-200X10<-4> at the polymerization temperature (e.g., isopropanol, methyl ethyl ketone, etc.), and saponifying the resulting PVAc, the above polymerization is carried out with the vinyl acetate monomer charged successively in accordance with the polymerization rate over the main polymerization period. Thus, an ultra-low-molecular weight PVA having a uniform molecular weight distribution can be produced with industrial advantage by keeping a substantial balance between the amount of the vinyl acetate monomer to be consumed and that of the vinyl acetate monomer to be added.

Title: Ultrasonic void defect detector
Inventor: MIYAJIMA TAKESHI
IPC: G01N29/44
Filed: 1992-04-07
Abstract: PURPOSE:To separate a void defect from a normal defect by moving an ultra sonic probe from immediately above a defect to a position with a predetermined angle or more shifted, detecting center frequency of a received echo signal and determining the void defect when a shift amount from the center frequency exceeds a threshold. CONSTITUTION:When a probe 16 having received a pulse signal from a pulse 1a applies an ultrasonic beam to an object 18, its center frequency (coinciding with the maximum peak) is high at the center and lower on outer parts. Therefore if a defect echo is detected from a slant direction, it shifts from the center frequency from a case where the echo is detected from immediately above the defect. Such an echo signal is received 1b, A/D-converted 2, stored in a waveform data memory 3 and stored in a RAM 6. At the time of detecting a void, the probe 16 is separated from the defect position by 0.5 deg. or more, the echo waveform is stored in the waveform data memory 3 to make frequency of the maximum peak the center frequency, and when difference between the center frequency and a center frequency of a hammered waveform of the probe 16 is at a certain value or higher, a void defect is determined.

Abstract: PURPOSE:To prevent the generation of a wrong stop signal, by lowering the level of the control signal of a stop signal generating circuit for searching broadcasting station and the level of a reference comparison voltage when noises in a spurious disturbing wave, etc., increase. CONSTITUTION:A signal of intermediate frequency from a front end part 1 is reduced in band through a band-pass filter 2 and then inputted to a level detector 4 through an amplifier 3 to supply a control signal corresponding to the intensity of an input electric field to a voltage comparator 6.
