IPC: A61B5/05
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To enable to quickly measure human body impedance simply only by touching electrodes by both hands, by equipping a mutually insulated pair of electrode pairs on both sides of a box to compose four terminal electrodes and measuring human body impedance by touching both hands to the four terminal electrodes. SOLUTION: On measurement of human body impedance, right and left hands are put on hand touching parts HL, HR of a control box 11 to simultaneously touch both palms onto power supply side electrodes HL1, HR1 and detect side electrodes HL2, HR2. When an AC voltage is applied to the power supply side electrodes HL1, HR1 in that condition, an AC potential is generated between the detect side electrodes HL2, HR2 via both hands. The AC potential is converted into a DC voltage, the wave form is shaped, and the level and the offset are adjusted, and then the DC voltage is inputted to CPU to calculate human body impedance. At that time, output characteristics of the detect side circuit are preliminarily calibrated for correction of measurement errors by aging changes and temperature properties of the element comprising the measure.

Title: Driving circuit for display device
Inventor: KAWAGUCHI HIROSHI
IPC: G02F1/133
Filed: 1993-11-18
Abstract: PURPOSE:To improve display dignity by imparting a display correction signal with a large amplitude to a pixel electrode in a vertical fly-back blanking period of a video signal when a picture is dark, an a correction pixel is required to be made dark. CONSTITUTION:When a discrimination circuit 17 judges that the whole picture is dark, switches an analog switch 15 based on a vertical fly-back blanking period discrimination signal C when the video signal A is in the vertical fly-back blanking period, and conducts a terminal 15b for the display correction signal instead of the terminal 15a for the video signal conducting until then. Thus, the display correction signal B is imparted to the pixel electrode of a liquid crystal display device 10 instead of the video signal A in the vertical fly-back blanking period. The display correction signal B is selected to a voltage waveform with amplitude as larger as possible. When the display correction signal B is imparted to the correction pixel, since the liquid crystal display device 10 is driven by a normally white mode, the transmissivity of light is lowered than a normal pixel in a defect pixel, and the picture becomes dark.

Filed: 1992-10-28
Abstract: PURPOSE:To reduce the possibility of malfunctions of electronic equipment due to static electricity by providing an IC having a pad between a pad which becomes the active side of an IC pad and a switch pad serving as an input line. CONSTITUTION:One end of an input line 4 is connected to a switch SW and the other end is connected to a circuit 1.

Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To provide a process for lowering the content of amines produced as by-products in decomposing a polyurethane and contained in a large amount in a regenerated polyol. SOLUTION: By reacting amines produced as by-products in decomposing a polyurethane by glycolysis and contained in a large amount in a regenerated polyol with an epoxy compound, the amines can be efficiently converted into hydroxy compounds that are quite nonproblematic even if they are present in the regenerated polyol.
