Abstract: An automatic frequency control circuit mounted on a mobile station in mobile communication.  The automatic frequency control circuit performs feedback control of an oscillation frequency of a local oscillator used in conversion of a reception frequency to an intermediate frequency signal in response to the count result of the frequency of the intermediate frequency signal.  If a receiver is not in the hand-off state, counting is performed for comparatively long time, if in the hand-off state, counting is performed for comparatively short time conforming to required stabilization performance at hand off.  Occurrence of variations in count values caused by fading is detected, and only the count values worthy of trust are used as a base of control.  A level drop caused by fading is compensated by self-oscillation.

Granted: 1997-05-06
Abstract: The invention relates to a hollow injection-molding method of forming a hollow portion in molten resin in a mold cavity by introducing a pressurized fluid, and also to a pressurized fluid introducing and discharging apparatus therefor, and has an object of eliminating the backflow of the molten resin to a pressurized fluid passage and surly introducing and rapidly discharging the pressurized fluid.    A gap between a cylindrical sleeve and a shaft core inserted into the sleeve is used as the pressurized fluid passage.  The front end of the shaft core is projected into a mold so as to be beyond the sleeve, and the projection portion of the shaft core is used as a guide face.  By sliding the shaft core, the state of an opening portion of the pressurized fluid passage in the side of the mold is changed from a narrowed state where the pressurized fluid can pass through the opening portion but the molten resin cannot enter the opening portion, to a widened state or vice versa.    The width of the opening portion of the pressurized fluid passage in the side of the mold is changed by sliding the shaft core, whereby the backflow of the molten resin is prevented from occurring and the pressurized fluid can be rapidly discharged.  The provision of the guide face allows the pressurized fluid to be surely introduced.

Title: Process for vitrifying asbestos containing waste, infectious waste, toxic materials and radioactive waste
Inventor: MOHR ROBERT KURT
IPC: C03B5/027
Filed: 1992-08-07
Granted: 2003-01-21
Abstract: Material, such as, for example, sealed double bags of as-bestos (24) containing waste or ash from infectious waste or toxic material or radioactive waste, is transferred into a glass melt of a furnace (10). Gas bubbles released into the melt form a gas curtain (12) which causes enhanced mixing of the materi-al to accelerate the dissolution of the components of the added material (7). The presence of the gas bubbles (12) reduces the cross section of the molten glass (32) through which current passes, which in tum increases the electrical resistance of the glass melt (32) or power density at constant current. A highly oxidizing hot region is produced under the location where the material is introduced into the furnace (10). Drawn off glass is shaped and quenched into at least two sizes of approximate spheres (23). The spheres (23) are cooled sufficiently fast to be thermally tempered and have a surface compressive strength le-vel above 5000 psi.

Abstract: In a PWM inverter using a three-arm modulation method, the apparatus and method are for controlling the current without missing the zero vector by switching the method to a two-arm modulation method near the voltage saturation. A PWM inverter using a three-arm modulation method comprises a timing data generating unit (32) which generates the timing data for the three-arm modulation based on the voltage vector times T.lambda., Tµ, and To from a PWM pattern operating unit (31), a timing changeover switch (33) which switches over this timing data to each phase time, and a timing data generating unit (41) which generates the timing data for the two-arm modulation from the voltage vector times. The zero vector time To is compared with the set value K,Tdly for the dead time comperisation by a comparison circuit (45) having the so-called hysteresis. Thus, if the zero vector time becomes short, the data generated by the timing data generating unit (41) are output to the timing change-over switch (33) by a modulation changeover switch (47) so that the PWM pattern is for the two-arm modulation method.
