Abstract: PURPOSE:To produce the subject raw material rod which is excellent without cracking and breaking the rod by kneading polycrystalline ferrite powder and binder and molding and sintering the mixture by using a sintered body which has a specific outside diameter and is formed with a hole having a specific inside diameter/outside diameter ratio. CONSTITUTION:The polycrystalline ferrite powder and the high-viscosity cellulose binder are added and kneaded at 1-10 pts.wt. ratio per 100 pts.wt. raw material and the mixture is molded and sintered by using the sintered body which has <=80mmphi outside diameter and 1/2-1/10 inside diameter/outside diameter ratio to produce the raw material rod for production of the ferrite single crystal in case of continuously producing the largesized and long-sized ferrite single crystal by using the raw material rod consisting of the sintered body. The excellent long-sized raw material rod is obtd. without cracking and breaking the rod. The fluctuation in characteristic by the compsn. segregation in the longitudinal direction of the crystal and the formation of the larger size crystal which are heretofore considered difficult with a Bridgman method are enabled by using this raw material rod. The capacity of single crystal production is thereby improved and the cost is reduced.

Title: Signal propagating circuit
Inventor: YAMAZAKI SHIGEO
IPC: G06F3/00
Filed: 1990-03-27
Abstract: PURPOSE:To decrease the calorific value as the whole device without depending on a circuit element by decreasing the time when all of driving circuits of a data bus, etc., which necessitate especially a large current are operated simultaneously. CONSTITUTION:Driving circuits 11 - 18 are placed so that the polarity of output signals is inverted alternately, and on an input circuit 20 side, as for negative signals 301-303, 305 and 307, they are received by receiving circuits 21, 23, 25 and 27 having a positive input. Also, as for driving circuits 12, 14, 16 and 18 in which the polarity of the output signal becomes positive, receiving circuits 22, 24, 26 and 28 having the negative input polarity are combined. Accordingly, when a logic circuit does not operate, all turning circuits do not operate simultaneously. Moreover, output signals 201-208 are handled as signals of negative logic in a logic circuit part of the inside. In such a way, since the heating value is suppressed, the use of a circuit element whose calorific value is smaller is made unnecessary.

Abstract: PURPOSE:To efficiently coat even the inner surface of a drum-shaped part similarly as the outer surface by projecting a deflecting means in the inner surface of the drum- shaped part joined to the outer surface of a wheel cover from the direction reverse to the spray direction and deflecting misty coating to the outside of the radial direction of the drum-shaped part by this deflecting means. CONSTITUTION:A deflecting means 12 described hereunder is provided to the inner surface 4 of a drum-shaped part 3 which continues to the outer surface 2 of a wheel cover 1 having a through-hole for a wheel nut. The deflecting means 12 is projected from the direction reverse to the spray direction Y so that it is not brought into contact with the inner surface 4 of the drum-shaped part. By this constitution, a spray gun 5 is moved and a coated film layer is efficiently formed on the outer surface 2 orthogonal to the advancing direction Y of coating. Simultaneously, the misty coating advanced to the inner surface 4 of the drum-shaped part is deflected to the direction nearly orthogonal to this advancing direction, namely toward the outside of the radial direction by the deflecting means 12. Misty coating is allowed to collide against even the inner surface 4 nearly orthogonally without waste.

Title: In-tube inspection instrument
Inventor: NAGAI SHINICHI
IPC: G01B21/00
Filed: 1987-03-31
Abstract: PURPOSE:To push a detection pig smoothly even in a pipe to be inspected which includes a vertical part by providing the detection pig with a buoyancy generating means. CONSTITUTION:Wheels 2a and 2b of the detection pig 1 are normally pressed against the pipe P to be inspected by shafts 3a and 3b with proper force and the driving wheel 2a is driven by a motor M. The pig 1, therefore, moves in the pipe P and a detecting means 54 performs inspection in the pipe. At this time, the rotation signal of the motor M and an electric signal for a means 54 are sent to and received from a control circuit 7 through a cable 53. Those correspond to a case wherein the pig 1 is at a position (a) within a nearly horizontal constant range. When the pig 1 is at a position (b) or (c), the constant range is exceeded and the pig is put in the antigravitational direction and begins to slip, so gas with low specific gravity is injected into balloons 5a and 5b from the circuit 7 through a gas cable 6. The movement of the pig 1 in the antigravitational direction is accelerated and made smooth by the buoyance generated by the injection. Then, when the pig returns to the case of the position (a), the circuit collects the gap and the balloons 5a and 5b are put back in storage tools 4a and 4b.

Abstract: PURPOSE:To efficiently and exactly measure the surface orientability of a high-polymer material having various shapes and smooth surface by projecting the light past a polarizer to the smooth surface of the high-polymer material from an approximately perpendicular direction and measuring the wavelength dispersion of the reflectivity of the polarized light. CONSTITUTION:The light past the polarizer is projected to the smooth surface of the high- polymer material from the approximately perpendicular direction.

The result of the measurement is converted to the wavelength dispersion of a refractive index n or absorption coefft. K in accordance with the equation I and the equation II or the equation III [where omega, omega0 are the frequencies of the light, R(omega) is the reflectivity at the frequency omega]. The peak value of the absorption coefft. K or the difference between the max. value and min. value in the wavelength dispersion of the refractive index n is detected and the absorption intensity in the respective polarization directions is determined. An orientation coefft. f is determined in accordance with the equation IV and the equation V (where D is the ratio of the absorption intensity, D0=2cot<2>gamma, gamma is the angle between the transition moment and high-polymer chain) from the resulted absorption intensity.
