Title: Pll circuit
Inventor: SUGIMOTO TOSHIRO
IPC: H03L7/14
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To instantaneously match a frequency division clock phase with a reference clock phase in a transient state at the time of the interruption restoration of reference clocks and power ON clear time. SOLUTION: Relating to this circuit, the output of a voltage controlled oscillator(VCO) 11 is frequency-divided into a reference clock frequency in a frequency division counter 12, the phase error of frequency division clocks and the reference clocks is obtained in a phase comparator 13 and the VCO 11 is controlled so as to eliminate the phase error. In this case, in the case of phase-delaying the frequency division clocks in a phase delay circuit 21 and supplying them to the phase comparator, differentiation pulses are generated by differentiating the reference clocks by the output timing of the VCO 11 by a differentiator 221, the input interruption/restoration of the reference clocks are detected in the clock interruption/restoration detection circuit 23 and the restoration detection output and power ON clear signals are monitored in a control circuit 222.  Then, at the time of restoration detection or power ON clear signal input, preset signals are supplied to the frequency division counter 12 at the timing of the differentiation pulses and the phase in a pull-in completion state is attained.

Title: Toothpaste
Inventor: INOUE KENJI
IPC: A61K8/46
Filed: 1980-02-14
Abstract: PURPOSE:A toothpaste composition having improved foaming properties preventing the change in taste of food after cleaning the teeth caused by a foaming agent, obtained by adding a specific ratio of a sodium alkyl sulfate, specified nonionic surface active agent and amino acid type surface active agent as a foaming agent to a toothpaste composition. CONSTITUTION:0.4-5.0wt% based on total amount of toothpaste composition nonionic surface active agent, 0.02-0.2pt.wt. based on 1pt.wt. nonionic surface active agent of sodium alkyl sulfate, and 0.05-2.0pts.wt. N-long-chain acylamino acid or its salt are blended with a toothpaste composition. The nonionic surface active agent is selected from the group consisting of a sucrose ester, polyoxyethylene stearyl alcohol ether, etc. Though the sodium alkyl sulfate has improved foaming properties, it has drawbacks such as changing the taste of a food after the use of toothpaste. The use of the surface active agent together with the sodium alkyl sulfate reduces the amount of the sodium alkyl sulfate used, so that the defects can be prevented.

Title: Synchronism detection device for orthogonal frequency division multiplex receiver
Inventor: MIYANO TAKESHI
IPC: H04L7/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous synchronism for multi-path phasing by switching a synchronizing signal from a detection edge into a pulse signal with a synchronism non-detection signal so as to execute demodulation. SOLUTION: A synchronism detection part 9 is connected to an edge detector 7 and a gate signal generator 8. When the edge is detected in a gate period, a synchronism detection signal is outputted. When the edge is not detected in the gate period, the synchronism non-detection signal is outputted. A switch 10 selected the output of the edge detector 7 and the pulse signal output of the gate signal generator 8. The output of the edge detector 7 is switched to the pulse signal output of the gate signal generator 8 with the synchronism non-detection signal of the synchronism detection part 9, and it is outputted to a demodulator 4 as a frame head. Namely, an operation load is reduced and erroneous synchronism is reduced since the judgment of pull-in is an operation at every frame synchronism. Thus, the precision of synchronism improves and the operation which is always stable can be obtained.
