Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To lessen the load of a general control means for a printer by executing speed control of a carriage drive motor through a hard logic circuit. SOLUTION: At the time of accelerating or decelerating a carriage drive motor 25, a pulse width control circuit 65 forms a pulse of predetermined duty ratio based on a duty ratio data for acceleration or deceleration received from a controller 40 comprising a CPU. When a carriage reaches a constant speed, a switch 64 is turned and a hard logic circuit 60 generates a duty ratio data for constant speed. More specifically, a detector circuit 61 detects the period of pulses outputted from an encoder 27 and a photosensor 28, a duty ratio operating circuit 63 generates a duty ratio data through PID(proportional, differentiating and integrating operation components) control and the pulse width control circuit 65 outputs a pulse of predetermined duty ratio. Respective coefficients for PID control are previously stored in a coefficient data memory circuit 62 from the controller 40.

Title: Digital type waveform signal generator
Inventor: YOSHIDA TAKUMI
IPC: H02M7/48
Filed: 1987-09-22
Abstract: PURPOSE:To improve the resolution of an output frequency without increasing the frequency of a reference clock signal by improving the set resolution of a frequency dividing ratio. CONSTITUTION:A frequency dividing ratio is set at a numerical value operated down to the first decimal place in the sexadecimal notation by a frequency dividing ratio setter 3. Then, the integer part n1 of said numerical value is inputted to an adder 14 and the decimal part M/16 (M is a value in the first decimal place), to an interpolation table ROM 15. The ROM 15 outputs the decimal part M/16 to a shift register 16. Said shift register 16 outputs a given bit of data to the adder 14 at the time of renewing an output signal to a waveform signal corresponding to each time section. Subsequently, said adder 14 adds the integer part n1 of the set value of said frequency dividing ratio and 1 bit of data inputted from the shift register 16 and outputs the added value as the frequency dividing ratio for a frequency divider 2. When the frequency of a reference clock signal is fCLK, an output frequency f0 is given by the equation shown on the right side. In this manner, it is possible to improve the accuracy of said output frequency.

Title: Spread spectrum communication equipment and system and interference reduction method in spread spectrum communication system
Inventor: PIITAA JIYON HOWAITO
IPC: H04B1/69
Filed: 1993-09-24
Abstract: PURPOSE:To eliminate the need of filtering by using waveform sets including plural amplitude signals equal to each other substantially by arranging at a prescribed interval so as to spread the input and to encode the signal thereby making the spectrum flat. CONSTITUTION:A frequency interdigital spread spectrum waveform is generated by using a RAM lookup table driving a D/A converter DAC. The sample of the generated spectrum waveform is stored in a RAM/ROM. Then data in response to the waveform including plural amplitude signals equal to substantially by arranging at a prescribed interval according to the clock from the RAM/ ROM are outputted. Then a low pass filter is used to eliminate an useless high frequency component and the result is converted into an analog signal and each signal is coded by spreading the information signal. Thus, the spread spectrum communication system is obtained, in which the spectrum is made flat and no filtering is required.

Accordingly, the contaminat hardly sticks to it, and the see-through performance of the translucent plate 3 is maintained in the good condition for a long term.

Filed: 1987-09-24
Abstract: PURPOSE:To diagnose the system of an extended station without interrupting the working of a LAN system by transferring a diagnosing frame produced newly at the side of the extended station to an existing station for execution of the LAN system. CONSTITUTION:When a new station is extended to a LAN, a diagnosising frame containing the diagnosing identification information on the addresses of its own station and the remote side station is sent to an existing station from the extended station 1.
