Title: Phase-locked loop circuit
Inventor: MAEDA MINORU
IPC: H03L7/08
Filed: 2000-02-25
Abstract: PROBLEM TO BE SOLVED: To suppress generation of spurious noise in the frequency and higher harmonic wave components of the frequency which uses the divider switching repeating frequency in a frequency synthesizer using fractional frequency division control technology. SOLUTION: In the PLL frequency synthesizer having a fractional frequency divider circuit capable of providing an average frequency dividing number (N+L/A) (N, L and A are integers) by switching the frequency dividing ratio of a variable frequency divider, when control is performed so as not to continue the same frequency dividing ratio more than two or three times by switching the frequency divider each time there is a output from the frequency divider, the fundamental wave and low-order higher harmonics wave components are decreased, however a high-order higher harmonic wave component are increased in the frequency and the higher harmonics wave component thereof defining frequency divider switching as the repeating cycle.  Since the high-order higher harmonic wave component can be easily removed by the LPF (loop filter) of a PLL, the frequency synthesizer having the fractional frequency divider circuit with less spurious noise can be provided.

Title: Coordinate inputting/detecting device and electronic blackboard system and position deviation correcting method for light receiving element and storage medium
Inventor: TAKEGAWA KENICHI
IPC: B43L1/04
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of the erroneous detection of position coordinates into which an instructing means is inserted due to the deviation of the mounting position (angle) of a light receiving element. SOLUTION: The waveform of a light reception signal corresponding to the intensity distribution of lights received by a light receiving element in a prescribed timing is compared with a reference waveform, and when it is judged that the waveform is not coincided with the reference waveform (Y of S9), it is judged that position deviation is generated in the light receiving element due to vibration or impact. Then, a reference waveform storing means (S2) is again carried out so that at a new reference waveform can be stored in a waveform storage part.  Thus, the waveform of the light reception signal corresponding to the intensity distribution of the lights received by the light receiving element in which the position deviation is generated is defined as the reference waveform so that any deviation can be prevented from being generated in a position relation between the peak point of the intensity distribution of the lights generated by a reference mark being the reference of position coordinate detection in a coordinate detecting means (S7) and the peak point of the intensity distribution of lights corresponding to an instructing means inserted into a coordinate inputting/detecting area. Thus, it is possible to prevent the generation of the erroneous detection of the position coordinates into which the instructing means is inserted.
