Title: Pulse output device
Inventor: ARAYA MAMORU
IPC: H03K3/72
Filed: 1979-12-19
Abstract: PURPOSE:To remarkably reduce the overhead time by program processing and to enable the control efficiently and with less error, against the control variable requiring continuous change, by continuously changing the output pulse width for the output only with one program designation. CONSTITUTION:The designation of the number of times of output of pulses output from the 2nd counter 22 and the integration start instruction are given to the 1st counter 20. Further, the overflow signal of the 2nd counter 22 subtracts the subtraction counter 21 by one, and the content of the subtraction counter 21 is preset to the 2nd counter 22. Further, the 1st counter 20 is repetitively operated with a given time interval to convert it into the pulse width designated with the subtraction counter 21 through the set of the number of output pulses once. Moreover, the output of specified number of times stops the pulse output with the overflow signal of the 1st counter 20.

IPC: G06F3/05
Filed: 1989-06-26
Abstract: PURPOSE:To prevent a data error to be caused by the deterioration of linearity by checking the data obtained after converting the produced plural types of reference analog data into the digital data and deciding the presence or absence of deterioration of the linearity in the A/D conversion. CONSTITUTION:An A/D conversion means ADC 4 receives the selected one of plural types of reference analog signals of different levels and an input analog signal. A data comparison means 5 compares the output of the ADC 4 with the reference digital data set previously at selection of reference analog signals and decides whether the coincidence is obtained or not within a prescribed grant range. Then it is checked whether the input/output characteristic linearity of the ADC 4 is deteriorated or not. Thus it is possible to prevent the output of he wrong analog data.

Title: Image forming device
Inventor: KOSUGE AKIO
IPC: G03G15/01
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To make the device small in size and installation area, short in transfer-paper carrying path, high in image output speed and improved in transfer-paper carry performance by specifying the length of the transfer-paper carrying path, from a registration roller to the first one of image carriers where transfer paper first comes. SOLUTION: Image forming units 21B, 21M, 21Y, and 21C for forming images in a plurality of separate colors, for example Bk, M, Y, and C, are arranged in a vertical direction T. The length of the transfer-paper carrying path, from the registration roller 31 to the first-color photoreceptor (the photoreceptor to which the transfer paper first comes) 22Bk, is made shorter than half the length of the passable smallest-side transfer-paper in the direction where the paper is passed. Therefore, because even when paper which is thin or small in size is passed as the transfer paper, the front end of the transfer paper is surely carried into a nip between the carrying transfer belt 26 and the first-color photoreceptor 22Bk, the transfer-paper carry performance improves, and a trouble, such a paper jam, and image-quality degradation due to rub of an unfixed image is not caused.

IPC: B60L50/16
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To control an AC motor stably, even in a transient period in which a torque command value or the rotating speed changes rapidly. SOLUTION: Until the absolute value of a voltage command value for each phase of an AC motor is less than A/2, where A is a value equivalent to a battery voltage (S105), a control by PWM(pulse width modulation) waveform voltage is conducted (S106). When the absolute value becomes A/2 or higher, a control by rectangular wave voltage is conducted (S113). Moreover, when either one of the voltage command values for each phase exceeds a maximum voltage value Vmax which can be generated by an inverter (steps S110-S112), the torque command value T* is decreased by ΔT (S114), and the voltage command value is re-calculated (S103). That reduced torque command value T* is notified to the ECU for control of a vehicles (S115).

This signal and a loading signal L are gated by a gate 16 to display the picture at the adequate lower position on a monitor television screen 5 through a playback signal processing circuit 4. The signal L is supplied to a voltage sweeping circuit 17 to move the display signal to right successively. Thus, an error in operation and an error in video recording are prevented.
