Abstract:
A semiconductor integrated circuit device is provided to reduce the adverse effect of PWM noise occurring in a PWM driving section on an analog voltage processing section in an IC, in which digital and analog circuits are combined on a single chip. A sampling signal generation circuit outputs a sampling signal St to an A/D converter at a predetermined time when “delay time td+allowance time ta” has elapsed from a start signal Sp. The delay time td is shorter than “the minimum time width of H level of PWM signal SPWM1−allowance time ta”. The delay time td is also time from the variation of level of the PWM signal SPWM1 to actual variation in the passage of current through a power section.
Abstract:
A memory control apparatus for controlling the operation of a memory array in a serial memory employs a command control section for registering the bits of an instruction which is received as an externally supplied set of serial data in conjunction with a corresponding series of cycles of a clock signal, with each set of serial data formatted as a command data portion preceded by a start bit, whereby the shifting of the start bit into the MSB stage of the shift register is detected and used to terminate supplying the clock signal to the shift register, thereby eliminating the use of a counter circuit. Any additional clock signal cycle following shifting of the start bit into the MSB stage of the shift register is detected, so that operating errors caused by noise in the received clock signal can be reliably eliminated.

A production system including a production line having a series of pieces of production equipment each of which has a parts supply unit. The production system includes: an NC management apparatus that is connected with each piece of the production equipment via a local-area network and acquires therefrom NC data used for operating each piece of the production equipment; and a scheduling apparatus that generates a production schedule and transmits the generated production schedule to the NC management apparatus via the local-area network. Here, the NC management apparatus generates, for each piece of the production equipment, data that is required to perform production according to the production schedule, obtains, for each piece of the production equipment, values that represent differences between current NC data that has been most recently acciuired and the generated data, and outputs the values.
Abstract:
In an A/D conversion device, one level shift circuit shifts an input voltage to the low potential side by Vt1, and another level shift circuit shifts the input voltage to the high potential side by Vt2. A multiplexer selects either of the shifted voltages to an A/D converter. In a correction mode, a correction data holding circuit holds values of reference voltages that are also A/D converted after being passed through the one level shift circuit and values of reference voltages that are A/D converted by being passed through the other level shift circuit, as correction values. A correction control circuit corrects the A/D converted value using the correction values.

Abstract:
A waveform shaping apparatus includes a comparing device for comparing a sensor output signal with a threshold voltage to convert the sensor output signal into a waveform shaped signal. The comparing device outputs the waveform shaped signal. The waveform shaping apparatus also includes a frequency-to-voltage converting device for generating the threshold voltage in response to a frequency of the output signal from the comparing device. In the frequency-to-voltage converting device, a clock signal is generated in response to the output signal from the comparing device. The clock signal has a period proportional to a period of the output signal from the comparing device. A counting device is operative for counting pulses in the clock signal generated by the clock signal generating device for every given period, and outputting a signal representing a counted pulse number depending on the frequency of the output signal from the comparing device. A D/A converting device is operative for converting the output signal from the counting device into a voltage signal which depends on the counted pulse number. The threshold voltage is generated in response to the voltage signal generated by the D/A converting device.
