It is an object of the invention to obtain a model formula for a circuit simulator that can be applied to a semiconductor device in which a channel length thereof becomes further shorter. A method of calculating a model formula for circuit simulation of a semiconductor device is provided. The method includes: calculating first parasitic resistance independent of gate voltage using actually measured data of the semiconductor device; calculating second parasitic resistance dependent on the gate voltage using IV characteristic of the semiconductor device from which the first parasitic resistance is removed; dividing the second parasitic resistance into channel resistance and third parasitic resistance generated under both ends of a gate length using plural kinds of diffusion resistance TEG in which the width W of each kind of diffusion resistance is the same as each other, but the length L of each kind of diffusion resistance is different from the other kinds of diffusion resistance; and obtaining an I-V characteristic formula for the semiconductor device using the third parasitic resistance as an independent characteristic.

An air passage switching device includes a case for defining an air passage, a butterfly door having a door body and a rotation shaft, a bearing part provided in the case for rotatably holding the rotation shaft, and a seal structure. The seal structure has a first seal part disposed at an outer peripheral portion of the rotation shaft to be integrally rotated with the rotation shaft, and a second seal part disposed in the case. The first seal part and the second seal part have scroll shapes centering on an axial center of the rotation shaft. The first seal part is in contact with the second seal part when the door body closes the air passage.

A first airbag apparatus of the present invention has an airbag module, which includes an airbag and an inflator, and a displacement mechanism, which displaces the airbag module. The displacement mechanism displaces the airbag module from an original position to a predetermined position when a collision of the vehicle is predicted and displaces the airbag module from the predetermined position to the original position when the predicted collision is avoided. A second airbag apparatus of the present invention has the airbag module and the displacement mechanism, which displaces a support member. The support member displaces the airbag from the original position to the predetermined position before the airbag is deployed. The deployed airbag is supported between the support body that is displaced to the predetermined position and an occupant.

In a motor driving device where a motor having a winding wire with small inductance value is driven by a digital control means comprised of control means including a current command value calculating means, a current control means and a PWM control means whose sampling periods are different from each other, when discrete signals sampled by the respective control means are zero-order-held, a motor current includes a lot of higher harmonic waves due to a quantization error, thereby increasing a motor noise. When an n-th-order hold means is provided between the respective control means with different sampling periods, the quantization error can be reduced remarkably, and thus the higher harmonic wave components included in the motor current are reduced, thereby greatly reducing the motor noise.

A data storage system comprises a temporary cache for temporarily storing data, a permanent cache for storing data for a predetermined period, and a memory selector for selectively having the temporary cache and the permanent cache store the data received by a terminal communicator. A data sorter sorts the data into temporary cache data to be stored in the temporary cache and permanent cache data to be stored in the permanent cache. In this way, it may be unnecessary to confirm whether or not the permanent cache data is updated in the permanent cache may be eliminated.

The present invention provides an iontophoresis system for non-invasively taking a physiological substance out of the living body, the system being suitably used for the mucous membrane. The present iontophoresis system non-invasively takes a physiological substance out of a living body. The system includes a plurality of electrode structures and a power supply device connected to the electrode structures. At least one of the electrode structures has a physiological substance extraction pad applied to the mucous membrane. In the present system, the time to apply electric energy to the living body by the power supply device is set between 30 seconds and 20 minutes. The physiological substance extraction pad which is provided in the electrode structure is applicable to the mucous membrane of the mouth and can be used, for example, to monitor glucose in the living body or an amount of drug administered.

According to the present invention, in cases where a CHA function and a DKA function are mounted within a single package, a battery power supply that is used during the occurrence of power supply trouble is effectively utilized so that the supply of power can be separately controlled for each function. A CHA part and DKA part are disposed in a single control package. When trouble such as a power outage is detected, the CHA part blocks access requests from the host, and initiates end processing. When the end processing of the CHA part is completed, the package internal power supply control part stops the clock supply to the CHA part. Then, when the DKA part completes destage processing, the package internal power supply control part stops the supply of power to the DKA part. The power consumption of the package is lowered in stages in accordance with the progress of the end processing.

Electroporation electrodes are laminated to a permeable membrane to form an electrode membrane. Such an electrode membrane is useful for a continuous controlled delivery of a therapeutic agent through the skin or mucosa, when placed in direct contact with the skin or mucosa and by application of electric field pulses at specified intervals. An electrode membrane can be assembled such that it incorporates an iontophoretic electrode in the same device. This device can be jointly utilized for electroporation and iontophoretic drug delivery through the skin and mucosal membrane.

The present invention provides an adhesive gel composition for iontophoretic formulations which is useful for the application through the skin or the mucosa, which excels in all of drug absorption, drug stability, gel shape retention and gel adhesion, which is easy to prepare and fill at the time of production, and which can be produced at low costs and a method for producing the same. The adhesive gel composition for iontophoretic formulations is produced by mixing an ionic synthetic polymer(s), a nonionic synthetic polymer(s), a naturally-occurring polymer(s), a polyhydric alcohol(s), a crosslinking agent(s) and a drug(s). In the production of the adhesive gel composition for iontophoretic formulations, oxygen dissolved in the gel is positively removed by carrying out replacement with nitrogen and/or vacuum kneading at the time of the ingredients are mixed and kneaded.
