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:
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.
摘要:
In a voltage detecting apparatus, a voltage controlled oscillator, when an input voltage is applied thereto, outputs a signal with a logical value that is periodically inverted. A detector counts a number of logical inversion of the output signal from the voltage controlled oscillator over an interval between edges of pulses of a pulse signal to thereby generate, based on the counted number of logical inversion, digital data as a detected result of the input voltage. A determiner determines whether a reduction of a time required to detect the input voltage is higher in priority than an increase of a resolution of detection of the input voltage. A variably setting unit variably sets a frequency of the pulse signal based on a result of the determination of whether the reduction of the time required to detect the input voltage is higher in priority than the increase of the resolution of detection of the input voltage.

A first bit-sequence, which is to be transmitted from a control section to an authentication chip according to an encoding scheme that transmits each one and zero by a pulse with a width of 200 μsec and 100 μsec respectively, is converted to a second bit-sequence to be transmitted according to NRZ encoding. The converted second bit-sequence is stored in a register with the MSB of the second bit-sequence aligned in the MSB of the register. Timing to set the pulse width for transmission of a one or zero by NRZ encoding is performed repeatedly, and at the start of each timed interval, the signal transmission level output to the authentication chip is set corresponding to the value of the bit stored in the MSB of the register. After setting the signal transmission level, the register is shifted left one bit.

Provided is an aligning method capable of setting a sample observation unit such as an optical microscope to a probe microscope observation position at high precision. A sample having a known structure is used in advance. A surface of the sample and a shape of a cantilever provided with a probe are observed using the sample observation unit such as the optical microscope. A sample observation position and a probe position which are obtained using the sample observation unit are verified, and a relative positional relationship therebetween is recorded. Then, a first mark indicating a position of the cantilever and a second mark which is displayed in conjunction with the first mark and has the relative positional relationship with the first mark are produced to align the sample relative to the second mark.
