Abstract:
PROBLEM TO BE SOLVED: To accomplish a base station system in which a sending time for a radio wave of an illegal frequency or a radio wave of an excessive output can be suppressed to a minimum by suppressing a transmission output from a radio transmitting/receiving section immediately when a frequency variation of a reproduction clock signal occurs in the radio transmitting/receiving section. SOLUTION: A reproduction clock signal included in an optical signal sent through an optical transmission line is detected by a deserializing section 203 and converted into a signal of a lower frequency by a mixing section 216, the frequency variation of the frequency-converted reproduction clock signal is detected by a detection section 219 via an HPF section 218 and replaced with a DC voltage variation, the frequency variation is detected in comparison with a reference voltage by a comparison control section 220 and if the frequency variation is detected, the transmission output is reduced in a radio transmission processing section 205.

PROBLEM TO BE SOLVED: To provide a PLL circuit which prevents loss of data or sequence processing even if a reference clock fluctuates during PLL operation. SOLUTION: The PLL control circuit which outputs a PLL clock in response to the reference clock is provided with a frequency adjusting circuit 45 for performing frequency adjustment so that the frequency of the PLL is substantially constant, even when the reference clock fluctuates. The frequency adjusting circuit 45 changes a set value of a counter for deciding the frequency of the PLL clock in accordance with the change of the reference clock frequency.

PROBLEM TO BE SOLVED: To provide a pointing device which generates a fixed control signal regardless of an operating direction, and prevents the generation of a control signal due to any erroneous operation, and also to provide electronic equipment capable of moving an object to be controlled on a display picture at a speed corresponding to the moving quantity of an operating part regardless of the direction. SOLUTION: When a point where the moving quantity of a slide key 1 is zero is defined as an origin, and the maximum value and minimum value of moving quantity when the slide key 1 is moved until butted to an opening peripheral edge are respectively defined as max-max and min_max, an arithmetic part 4 sets the strength of a control signal as zero when the slide key 1 is positioned in a circular area whose radius is the n/N times of max_max (n and N are arbitrary positive integers and n is less than N) with the original point as a center, and sets the strength of a control signal as strength corresponding to the moving quantity of the slide key 1 when the slide key 1 is positioned in a circular area whose radius is more than n/N times of the max_max and not more than min-max, and sets it as the same strength as the moving quantity of the slide key 1 is min_max when the slide key 1 is positioned in the area whose radius which is more than min_max.

PROBLEM TO BE SOLVED: To provide the manufacturing method of a thin film transistor, suppressing a back gate effect by the charge-up of an oriented film and a spacer at the upper part of the TFT, and to prevent the voltage-holding defect of a pixel electrode part. SOLUTION: After forming semiconductor layers 4a and 4b via a gate insulating film 3 on an insulation substrate 1, the semiconductor layers 4a and 4b are patterned and a channel part is formed. Then, a passivation insulation film 7, covering the semiconductor layers 4a and 4b, is formed. After the formation of the channel part and before the formation of the passivation insulation film 7, a first plasma treatment 16 is executed by using a first gas (gaseous oxygen, for instance) and a second plasma treatment 17 is executed further by using a second gas (gaseous hydrogen, for instance).

Abstract:
PROBLEM TO BE SOLVED: To provide a resource assigning method which is economical and is easy for designing and to provide a wireless base station apparatus. SOLUTION: When a call connection request is given to a call processing control part 4, the call processing control part 4 multicasts a resource assignment request message to a signal processing card 51 and a signal processing card 52. The signal processing cards 51 and 52 receiving the resource assignment request retrieve as to whether there is a required spare resource in their own cards and transmit a resource assignment response message showing the acceptance/rejection of resource assignment to the call processing control part 4. The call processing control part 4 receiving the resource assignment response transmits a resource assignment processing message to a signal processing card which has transmitted the resource assignment response showing resource assignment acceptance which is first received, and makes the signal processing card perform resource assignment.
