Patent JP-H01221963-A (JP)
Title: Printer
Inventor: YOKOI TAKAAKI
IPC: H04L13/08
Filed: 1988-02-29
Abstract: PURPOSE:To set a reception interval at a time fitted in the actual operation of a printer and to prevent a receivable time from being continued for a long period by deciding the reception interval from a host device by a reception buffer and the number of pages waiting for output. CONSTITUTION:Data sent from the host device is received at a reception part 11 in the control part 1 of a printer, and it is stored in the reception buffer 12. Also, an edit circuit part 13 takes out reception data from the oldest one in the buffer 12 sequentially, and after being converted to the data possible to be printed by a print output part 2, it is stored in a page buffer 14. When the edit is completed at the edit circuit part 13, a page count value is increased by one. Also, one is subtracted from the data of a page when the data of one page is delivered to the print output part 2, and the reception part 11 refers to the page count value, and calculates a time required for the ejection of all data, and a result in which the number of vacant bytes in the buffer 12 is divided is supplied to a timer 15, and when the timer 15 completes counting, the reception part 11 is started up.

Title: Light quantity control system in image input device
Inventor: HOUKI YOUJI
IPC: G03B27/72
Filed: 1979-04-17
Abstract: PURPOSE: To obtain always equal image signals despite the change in scanning speed by so constituting the system that an image sensor is provided in a read head and the intensity of the light of a light source is controlled by the magnitude of the integrated time of the light received thereby.  
     CONSTITUTION: A read head 5 is built in with an image sensor 2. A counter 15 outputs a pulse signal to reset an integrator 17 when it counts the pulses of a speed detector 9 to the specified value. When the scanning speed of the read head 5 is nearly normal, the output of the integrator 17 reaches nearly the normal value and the voltage of a lamp 4 assumes a standard value. However, if the scanning speed lowers owing to cause such as friction, the pulse interval of the output pulse train of the speed detector 9 becomes wider and the time when the counter 15 counts the specified pulses becomes longer. As a result of this, when the output of the integrator 17 exceeds the normal value, the lamp voltage becomes lower by this excess portion and the intensity of the light of the lamp 4 is weakened correspondingly. Thus, even if the scanning speed changes, always equal image signals may be obtained.

Title: Power source and method of suppressing radiating electromagnetic disturbance for power source
Inventor: AASAA JIYAIGA BURATSUKU
IPC: H02M3/28
Filed: 1991-02-21
Abstract: PURPOSE: To suppress a high-frequency electromagnetic radiated interference in a switching mode power supply. CONSTITUTION: The present invention minimizes EMI, by dividing a parallel electric connection between the diodes connected to the secondary coil of an orthogonal switching mode power supply circuit. A conductor 32 is serially connected to a diode 36 to give a first impedance, and a conductor 34 is also serially connected to a diode 38 to give a second impedance. The conductors 32, 34 have a stray inductance, a resistor and a capacitor. These have a control circuit network themselves. The present invention reduces radiated EMI by utilizing an impedance of the secondary coil 30 and difference of the electrical characteristics of the conductor itself. The function for effectively controlling the radiated EMI can be obtained by individually adjusting each impedance.

Abstract: PURPOSE:To provide a gate electrode and wiring, where hillocks are hard to occur and which are flat and are easy to be anodized, by adding Cu or Ni to Al. CONSTITUTION:As the material used for a gate electrode and wiring, an electrode material mainly composed of Al is used, and as an additive metal, Cu and Ni are selected. Cu is effective for electromigration, and Ni has an effect on suppression of hillock generation. As the result of having investigated the surface roughness by the addition of Cu or Ni to Al, which becomes the criteria of hillock, and the value of sheet resistance, which causes signal delay, by experimentation, it was found that Al-1wt.%Cu or Al-3wt.%Ni was much better in surface roughness than an electrode, where Si is added to Al, that the sheet resistance value of Al-1wt.%Cu was much better than Al-1wt.%Si or Al-3wt.% Ni, and that the anode oxide film of Al-1wt.%Cu fulfilled the mechanism as an insulating film enough. Accordingly, it can be flattened by preventing the hillock, using an At-Cu material, where 1% Cu is added to Al, for a gate electrode or wiring.

Abstract: PURPOSE:To restrain the effective channel length from shortening by a method wherein an electrode connecting to at least a storage electrode for capacitor out of the electrodes of MOS type transistor for memory cell is covered with a mask. CONSTITUTION:An electrode 16 connecting to at least a storage electrode 14 for capacitor out of the electrodes of MOS type N channel transistor for memory cell is covered with a mask covering a P type transistor part in ambient circuit during phosphorus ion implanting process for the formation of N<->region in LDD(lightly doped drain) structure of the N channel transistor.

However, the impurities are diffused from the contact part of the storage electrode 14 for capacitor with a cell transistor during the process after the formation of said electrode 14 so as to form the phosphorus diffused region in the peripheral part of an N<+> diffused region. Through these procedures, the phosphorus concentration in the region near the channel is lowered to restrain the effective gate length from shortening.
