IPC: H02K15/03
Filed: 1988-06-23
Abstract: PURPOSE:To obtain a small and highly efficient motor at low cost by employing rear earth element-transition metal-boron as basic composition and subjecting the composition to hot machining. CONSTITUTION:Rear earth elements, transition metal and boron are weighed at specific ratios and cast in an induction furnace, then a cast ingot 201 is covered with a pure iron sheath 202. Then it is passed through a caliver roller comprising a convex upper roller 301 and a concave lower roller 302 corresponding to the curvature of the permanent magnet for generator and subjected to hot rolling under the temperature of 950 deg.C thus producing an anisotropic magnet. Thereafter, the permanent magnet is subjected to a thermal treatment under the temperature of 1000 deg.C for 24 hours thus producing a permanent magnet associated with the sheath 202. Since the pure iron sheath 202 is used as a yoke 102 and integrated with the permanent magnet 101, the border between the permanent magnet 101 and the yoke 102 is jointed in solid state thus providing a sufficient adhesion.

Title: Digital phase-locked loop circuit
Inventor: DESOR HANS-JUERGEN
IPC: H04N9/87
Filed: 1991-06-27
Abstract: PURPOSE: To provide a digital phase-locked loop circuit capable of being securely and stably operated, even if an aperiodic synchronization pulse is generated and accurately addressing horizontal frequency video signal processing operation with the phase of a digital oscillator. CONSTITUTION: To adjust a period of a digital oscillator 10 to a nominal period determined by synchronization pulses which are generated periodically, a processor 100 compares the actual phase of the digital oscillator 10 with a set at the control clock rate of the periodic synchronization pulses. After the digital oscillator 10 has been synchronized with the nominal period, the processor 100 makes a phase comparison in the signal sequence of line cycles which are a half as long as the digital oscillator output signal. The digital oscillator output signal is sent out to a correcting device 110 to generate an address phase signal, which is synchronized with the digital oscillator output signal.  Therefore, an address phase signal is shifted by only one cycle of the signal sequence of one half of the line cycles with respect to the digital oscillator output signal with the aperiodic synchronization pulses.

Since the org. compd. having the tetrazole ring has a short pi conjugation length, the absorption wavelength end is as short as <=400nm. The method for synthesizing the tetrazole ring; for example, 1-hydroxtetrazole, is executed by dissolving disodium tetrazole-5- carboxylate under stirring in pure water and adding hydrochloric acid to the soln. to effect reaction. The reacted product is filtered and is refined by recrystallization with n-butanol. An Nd:YAG laser (1064nm) is made incident on the 1-hydrotetrazole of a white powder crystal form synthesized in such a manner, by which SHG (second harmonic generation) is observed.

In case the frequency of the crystal 11 changes by the aging characteristics and the frequency of the VCO15 is set at H shown in a figure, the variable resistance RV is changed to vary the DC voltage applied to the diode 14. Then the capacity C2 is changed to C2', and the frequency of a VCO15 is changed so that the microwave frequency obtained by multiplying and synthesized the VCO frequency is set at G shown in the figure. Thus an atomic resonance frequency is locked in again and the VCO15 delivers a stable frequency.
