Title: Power saving frequency synthesiser with fast pull-in feature
Inventor: SATO MASUJIRO
IPC: H03L7/14
Filed: 1992-08-21
Abstract: In a frequency synthesizer, a first, variable frequency divider 3 and a second frequency divider 5 are activated in response to a periodic power activation pulse. The first frequency divider is driven by a voltage-controlled oscillator 1 and the second frequency divider is driven by a reference frequency oscillator 7. A timing difference between the outputs of the first and second frequency dividers is detected and converted to a frequency-domain control signal for coupling to the voltage-controlled oscillator. Since the timing difference is converted to a frequency domain signal, the VCO is stabilized once there is a substantial frequency match between the first and second frequency dividers. Since the VCO can be stabilized thereafter, the frequency dividers can be deactivated when the detected timing difference is reduced to an acceptable value and are allowed to remain inactive until the synthesizer is activated again by the next activation pulse. <IMAGE>

Title: Controlling washing period according to turbidity change
Inventor: WADA MASATSUGU
IPC: D06F34/22
Filed: 1993-10-14
Abstract: In a control device for an automatic washing machine, a first change in the turbidity of a wash liquid is detected. A time period of the wash step is determined on the basis of the detected change of turbidity. The wash step is completed upon lapse of the determined time period of the rate of change in the turbidity of the wash liquid in a short period upon lapse of the wash step time period is at a predetermined value or below. When the turbidity change rate is above the predetermined value, the wash step time period is extended. The period of extended time may be selected in accordance with the first change in the turbidity. The period of time over which the first change in turbidity is measured corresponds to the time required for detergent to dissolve.

Title: Transmission system performance test using pseudo-random patterns
Inventor: NEGI KEIJI
IPC: H04B1/7073
Filed: 1995-06-19
Abstract: A testing device is provided to test performance of transmission systems such as communication devices and transmission lines by transmitting and receiving specific patterns called pseudo-random patterns (i.e., PN patterns). A receiver unit of the testing device provides a synchronization detecting circuit. The synchronization detecting circuit comprises a pseudo-random-pattern creating circuit 4, a first coincidence detecting block 1-1, 2-1, 3-1, a second coincidence detecting block 1-2, 2-2, 3-2 and an OR circuit 5. The first coincidence detecting block detects coincidence between a receiving-data input 6, a first detected-pattern input 7-1 and a pseudo-random pattern created by the pseudo-random-pattern creating circuit so as to produce a first coincidence detecting signal. The second coincidence detecting block detects coincidence between the receiving-data input, a second detected-pattern input 7-2 and the pseudo-random pattern so as to produce a second coincidence detecting signal. The first and second coincidence detecting signals are applied to the OR circuit, by which a synchronous detection signal is produced. Thus, synchronization between the receiving-data input and pseudo-random pattern is detected by the synchronous detection signal. Incidentally, each of the first and second detected-pattern inputs receives the pseudo-random pattern transmitted thereto through the transmission system; and the second detected-pattern input is delayed behind the first detected-pattern input by 'm' bits (where 'm' is an integer which is determined in advance). <IMAGE>
