Patent JP-H0487565-A (JP)
Title: Switching regulator
Inventor: FUKUCHI TAKESHI
IPC: H02M1/00
Filed: 1990-07-25
Abstract: PURPOSE:To improve power factor by finding the average of currents passed through a switching element and, when the average is not higher than a specified value, turning on a bypass switch, otherwise, turning off a bypass switch. CONSTITUTION:A current detector (a) continuously finds the average of currents passed through a switching element 11. When the current detection value is not larger than a specified value, a bypass switch controller 7 of a comparatively small output current in stand-by or normal operation turns on a bypass switch 5, short-circuits both terminals of a choke coil 4, and acts as a capacitor input type device. When its output current becomes larger and the current detection value is larger than a specified value, it turns off the bypass switch 5 and acts as a choke input device. Thereby power factor at the time of large output is improved.

Abstract: PURPOSE:To attain a noise barless varying speed reproduction by writing and reading a reproduction signal at the clock of the prescribed frequency in and from a field memory every (n-1) fields or every field at the time of reproducing the signal at n-fold or 1/n-fold speed. CONSTITUTION:At the time of reproduction at n-fold speed, changeover switches 3 and 4 are connected to the side of P.B, and a reproduction signal is transmit ted to a switch 12 through reproduction amplifiers 10 and 11. The switch 12 is alternately switched by an HSW signal, and the reproduction signals of one field are written in a field memory circuit 13 at the clock of a frequency nf1 (f1: frequency of video signal) every (n-1)fields. Data in a memory 13 is read out at the clok of the frequency f1 to obtain a video signal through a reproduc tion luminance signal processing circuit 14 and a preproduction chrominance signal processing circuit 15. At the time of reproduction at 1/n-fold speed, all fields of the reproducing signals are written in the memory 13 at the clock of the frequency f1/n every field, and read out at the clock of the frequency f1, thereby obtaining a video signal. Thus the video signal free from a noise bar can be obtained.

Abstract: PURPOSE:To accurately grasp a heart beat condition by providing a control means for indicating an impedance pulse wave when the detection of pressure pulse waves on the portion to which an electrode is attached becomes abnormal. CONSTITUTION:A pulse wave detecting probe 12 is fixed onto the artery 10 on the wrist by means of a supporting band 14 and, as pressure pulse waves are detected, the pressure pulse waves and the pressure P1 in a housing 16 are stored by a RAM.

Then, the actual highest blood pressure value H and lowest blood pressure value L are determined and stored and, as the measurement of a blood pressure value is completed, at the point of time when pressure pulse waves of (n) in number are stored, the average value of the amplitude value thereof and the average value of the amplitude value of impedance pulse waves are calculated and compared to judge the abnormality of pressure pulse waves. When the pressure pulse waves are judged to be abnormal, the highest value mImax of an impedance pulse wave MI1 and the lowest value mImin of the impedance pulse wave MI1 detected from a differential amplifier are determined to calculated the highest blood pressure value and the lowest pressure value. Hence, the heart beat can be accurately grasped.
