摘要：リアル・タイム・クロックのブラウンアウト検知の方法および装置である。全地球測位システム（「ＧＰＳ」）受信機の幾つかの構成部品が電力を落とされている間、低電力リアル・タイム・クロック（ＲＴＣ）は、受信機の時刻を継続的に保持する。様々な実施形態で、ブラウンアウト検知回路はＲＴＣクロック・サイクルの喪失を検知する。ＲＴＣクロック・サイクルの喪失が所定のしきい値を超えて、それによりＲＴＣがＧＰＳナビゲーションにおいて信頼できなくなると、ＲＴＣステータス信号がそのことを示す。

摘要： PURPOSE:To provide a melody generation device capable of performing exercise while enjoying by giving a sound according to the required acoustic data from the acoustic data of plural kinds of melodies. CONSTITUTION:This device is constituted so that when a melody selection switch 3 is operated, an address signal of an address counter 2 is revised, and the acoustic data of the melody according to the revised address signal are read out from an acoustic data storage circuit 1 at a read pitch set by a read pitch specifying circuit 4, and the acoustic data of the read melody are converted into an analog signal by a D/A conversion circuit 6, and the converted signal is amplified by an amplifier 7 according to the volume set by a volume adjusting circuit 13 to be emitted as sound from a speaker 8.

摘要： PURPOSE:To obtain a pace generator which can output a desires pace automatically without interrupting the motion of a user while reducing power consumption. CONSTITUTION:A walking detecting means 103 detects walking and outputs a walking signal to a walking pace operating means 104. According to the period of the walking signal, the operating means 104 operates a pace and stores it in a walking pace memory means 105. A pace comparing means 106 compares a set pace stored in a pace data memory means 107 with the walking pace stored in the memory means 105 and outputs a pace generation command to a pace signal generating means 109 if the walking pace deviates a range preset for the set pace. The means 109 generates a pace signal corresponding to the set pace and delivers a pace signal to a pace output means 110 thus producing a pace.

摘要： PURPOSE:To provide a clock supply circuit which detects the ringing of an output clock signal basing on the error signal produced between a source clock signal and the output clock signal of the clock supply circuit and then automatically select a damping resistance to minimize the ringing. CONSTITUTION:An error signal extracting means 6 extracts a difference signal produced between the source clock signal of a clock oscillator 2 and the clock signal of an output terminal 5 of a clock supply circuit. The comparator means 14 and 17 compare an error signal 6a with threshold voltage levels 15 and 16 via peak value detector means 8 and 9 and peak value storing means 10 and 11, respectively. Then, a damping resistance selecting means 20 is controlled basing on the results of comparison of both means 14 and 17. Thus, the optimum one is selected out of a group 4 of damping resistances.

摘要： PURPOSE:To obtain a hydraulic clock which displays at a high accuracy with a small motive power by controlling a motor by detecting the hydraulic turbine rotating error from the index pulse of the rotating speed of a hydraulic turbine and the standard pulse of a standard clock, and increasing or decreasing the water volume in a water reservoir so as to correct the error. CONSTITUTION:A water level sensor 54 detects the water level of a water reservoir 3, and when the water level reaches a specific height or higher, or less than a specific amount, a motor 52 is stopped, and the pumping up of the water by a water supply pump 53 is stopped. And an index pulse generated by a rotation speed detector 46, and a standard pulse generated by a standard clock 44 are compared, so as to detect an error of the rotating speed of a hydraulic turbine 2, and the drive of the motor 52 is controlled depending on this error, to increase or decrease the water amount in the water reservoir 3, so as to correct the error. Consequently, the error can be corrected by a small motive power, and a highly accurate display can be made.
