摘要:
A micro-channel device provided in a solution analysis system using pressure liquid feed comprises a plurality of straight-line channels and curved channels connecting the ends of the neighboring straight-line channels. The width w of each curved channel is smaller than the width t of each straight-line channel. The radius of curvature r of each curved channel is set so that the value of a expressed by formula (1) is equal to or smaller than the value of a at a local maximum point of the theoretical step height H expressed by formula (2) and based on the shape of the curved channel. a=w/r (1) H = u c w 2 64 γ D m × a 2 ( a + 2 ) a + 1 ( 2 ) Where, w is a width of the curved channel, uc is a channel passing speed of a solution in the curved channel, γ is a molecular diffusion inhibition factor by basic members present in the curved channel, and Dm is a molecular diffusion coefficient of the solution.

An inverter device that controls a motor using a signal from a position sensor for detecting a rotor rotational position of the motor includes an initial adjustment unit that outputs a phase of current for designating a motor rotational position by rotating the motor in a clockwise direction of the motor and a phase of current for designating the motor rotational position by rotating the motor in a counter-clockwise direction of the motor.
摘要:
A first analyzing step is a step that conducts numerical analysis of a flow field but does not conduct numerical analysis of a temperature field in a state in which a motor rotor is rotating. The second analyzing step is a step that conducts numerical analysis of both the flow field and the temperature field after the first analyzing step ends. Accordingly, before numerical analysis of the flow field and numerical analysis of the temperature field are conducted together, numerical analysis is conducted first on the flow field in first analyzing step before it is conducted on the temperature field. As a result, compared with when the second analyzing step is executed from the beginning without conducting the first analyzing step, the calculation load of the numerical analysis on an electronic calculator can be reduced, which enables the time that it takes to conduct the numerical analysis to be shortened.

A communication device is driven by an on-demand driver installed in an apparatus that includes an on-demand driver generating program that generates the on-demand driver for the communication device based on device information of the communication device. The communication device includes a memory unit that stores therein the device information of the communication device, a responding unit that, in response to a request for obtaining the device information from the on-demand driver generating program, sends the device information stored in the memory unit to the apparatus, and an updating unit that is used in externally updating the device information stored in the memory unit.
摘要:
The state monitoring apparatus includes a high-voltage side monitoring section having monitoring units assigned to respective unit batteries and a low-voltage side monitoring section having a control device. The monitoring units measures the voltages of the unit batteries upon reception of a voltage measurement command transmitted from the control device, and determines whether or not the measured voltages are within a predetermined range. This determination is transmitted to the control device. If this determination is negative, the control device limits a charge/discharge current of the assembled battery, and then causes the monitoring units to transmit the measured voltages.

摘要:
A vehicle power supply apparatus has first and second engine-driven electrical generators and first and second storage batteries, the first generator supplying a stable voltage to the first battery and a first set of loads, and the second generator supplying the second battery and a second set of loads, which can tolerate supply voltage variations. Operation of the second generator and charging/discharging of the second battery are controlled to maintain the total engine torque applied to the generators at a level whereby fuel consumption is reduced, while the supply voltage of the variation-tolerant loads is allowed to vary substantially.

摘要:
In an A/D converting apparatus, a converting unit has an input terminal and an input-output characteristic. The input-output characteristic has temperature dependence, and the converting unit carries out a process of converting an input voltage signal to digital data. A temperature determining unit has information representing a relationship between a variable of an output of the converting unit and a variable of a temperature around the converting unit according to the temperature dependence of the input-output characteristic of the converting unit. When the specified voltage is applied to the input terminal of the converting unit, the temperature determining unit determines a value of the temperature around the converting unit based on the information and the specified voltage. A reducing unit reduces temperature dependence of the process of converting an input voltage signal to digital data based on the determined value of the temperature around the converting unit.
