Title: Synthesizer circuit and oscillation frequency control method
Inventor: SAITO SHOJI
IPC: H03L7/18
Filed: 1993-03-15
Abstract: PURPOSE:To recover an oscillating frequency getting higher in excess of a frequency division capability into a stable state. CONSTITUTION:When an oscillated frequency of a VCO 13 is increased in excess of a capability of a 1/N frequency divider 14, since no frequency division signal is outputted from the 1/N frequency divider 14, a oneshot multivibrator 21 monitors the state. When the frequency division signal is not detected even after elapse of a predetermined period, a transistor(TR) 22 is turned off with the output of the one-shot multivibrator 21 till the frequency division signal is detected. Thus, a control signal outputted from a phase comparator and charge pump circuit 11 to the VCO 13 is interrupted to forcibly decrease the oscillated frequency from the VCO 13 thereby recovering the state to a stable state.

IPC: A61L9/01
Filed: 1986-03-13
Abstract: PURPOSE:A powdery deodorant showing improved deodorizing effects on body smell such as axillary odor, body odor, etc., containing specific microcapsules obtained by covering deodorizing solid powder with an inorganic substance of wall material such as magnesium silicate, etc., as an active ingredient. CONSTITUTION:Powdery deodorant containing approximately completely spherical inorganic microcapsules having 1-10mum average particle diameter as an active component, obtained by covering solid powder having deodorizing effects as a core material with an inorganic substance selected from silica, magnesium silicate, calcium silicate and calcium carbonate as a main component of wall material. Since a great number of fine pores communicated with inner space exist in the wall material of shell consisting essentially of the inorganic substance, bed smell components are passed through the fine pores, brought into contact with the solid powder and deodorized. Furthermore, since the wall material is porous, has large specific surface area and effectively deodorizes body smell. Since the solid is not directly exposed to the outside, safety to skin irritation, etc., is also improved.

And wave of an output of the beam-receiving unit 6 is synchronously detected with an output of the beam-receiving unit 6' as a reference source. It is possible, by doing so, to measure wavelength of even a weak input beam with high accuracy.

Title: Fuel replacing method for fast reactor
Inventor: SUZUKI TOSHIYUKI
IPC: G21C19/19
Filed: 1990-03-06
Abstract: PURPOSE:To simplify fuel replacing facilities by drawing used fuel in order while a reactor upper mechanism is lifted by a specific quantity when the used fuel in the area right below the reactor upper mechanism is drawn out. CONSTITUTION:In the rear right below the reactor upper mechanism 6, the mechanism 6 is lifted by about 1m through a lift-up/down device 8. Then fuel replacing devices 17a and 17b are used to draw only the used fuel from the outer periphery to the center. At this time, the quantity of eccentricity of a gripper 27 is adjusted and at the position where the mechanism 6 is locked, a reactor core constitution element 33 is drawn out exceeding the overall length. Then the devices 17a and 17b are swiveled and the quantity of eccentricity of the gripper 27 is adjusted to perform conveyance to a fuel carry-in/out position 9. Thus, the used fuel is drawn out and while the mechanism 6 is still lifted, the devices 17a and 17b are used to charge new fuel from the outer peripheral side to the center of the reactor core 2. Thus, the mechanism 6 is only lifted by about 1m to enable the fuel replacement.
