Title: Phase lock detecting circuit
Inventor: TANIGUCHI TERUTAKA
IPC: H03L7/089
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To attain phase lock detection for a PLL circuit which is packaged into one from which the inside intermediate generation signal cannot be extracted. SOLUTION: An input reference signal 32 to an integrated PLL circuit 30 is inputted to a counting period generating circuit 42, and a counting period signal pulse having pulse length which is prescribed times as long as the cycle is generated synchronously with this. An output signal counter 44 uses this counting period signal pulse as an enable signal, and counts the number of waves of an output signal 34, outputted from the integrated PLL circuit 30 in the pulse period. A reference count value which is preliminarily decided based on the design values of the time length of the counting period signal pulse and a frequency conversion rate in the integrated PLL circuit 30 is set in a count value comparator circuit 48.  A lock-judging circuit 46 judges the state of the phase lock between the input and output signals of the integrated PLL circuit 30 from the size of the reference count value and an output count value measured by the output signal counter 44.

Title: Protecting circuit of loudspeaker
Inventor: HACHIMAN YASUROU
IPC: H04R3/00
Filed: 1981-08-20
Abstract: PURPOSE:To protect a tweeter from the overload, by connecting a lamp having the internal resistance smaller enough than that of the tweeter in series to the tweeter. CONSTITUTION:A lamp PL1 has the internal resistance smaller enough than that of a tweeter SP1. Thus the PL1 is virtually no function as an attenuator to the tweeter driving current if the tweeter driving voltage, i.e., the lamp application voltage is less than a certain level. While the voltage higher than a certain level is applied to the PL1 by synchronizing an FM tuner with the inter-station level and then applying the inter-station noise to the SP1. As a result, the internal resistance of the PL1 increases suddenly and functions as an attenuator to the driving current of the SP1. In other words, the increase of te internal resistance which is caused by the heat of the PL1 is carried remarkably suddenly in comparing to SP1. As a result, the combined resistance of the PL1 and a voice coil is greatly increased, and the increase can be reduced for the current which flows to the SP1 in the overload mode.
