Title: Level conversion circuit
Inventor: SUGIZAKI SHIRO
IPC: H03K19/0185
Filed: 1988-12-02
Abstract: PURPOSE:To attain stable level conversion without malfunction even in the presence of temperature fluctuation by providing a temperature compensation circuit section and deviating a gate-source voltage of a transistor(TR) for a current source in a direction cancelling the fluctuation of a threshold level of a logical inversion section due to temperature fluctuation. CONSTITUTION:If a forward drop voltage of diodes D1, D2 change respectively by -VT due to temperature rise, A level of a point B being a source electrode of a TR QD is fluctuated by 2X(-VT). Thus, the logical threshold level in the case of inputting a level of a point A is fluctuated by 2X(-VT). In this case, A gate-source voltage VGS of a TR QC is biased to be changed by 2XVT in a direction to cancel the fluctuation 2X(-VT) of the logical threshold level due to the said temperature rise. Thus, the fluctuation of 2X(-VT) of the potential at the point A due to the fluctuation of the said VGS is cancelled out and the fluctuation of the logical threshold value is suppressed. Thus, the signal subject to level conversion being outputted to an output terminal 2 is extracted as a signal whose temperature fluctuation is compensated.

Title: Differentiation method of sensitive skin
Inventor: KASHIBUCHI NOBUO
IPC: G01N1/04
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To achieve an effective differentiation of a sensitive skin ideal in the judgment for the selection of a cosmetic product and the prevention of skin troubles by using a specific area of corneocyte as index based on the comparison of the size of the corneocyte with the standard size of the corneocyte determined in terms of age. SOLUTION: There is a better linear relationship between two variables related to the normal corneocyte and the age and hence, the standard area of the normal corneocyte can be expressed by a function of the age. As the standard corneocyt contains season as factor, the season is incorporated as factor to allow the calculation of a correct standard area of the corneocyte. In the differentiation of a sensitive skin, the measured area of a corneocyte of an examinee is compared with the standard area of the corneocyte calculated as base. When the area of the examinee is almost the same as the standard area of the corneocyte, ordinary skin is presented. When the measured area of the corneocyte is smaller than the standard area thereof, sensitive skin is determined.
