Abstract: PURPOSE:To increase the processing speed by summing points of characters included in a character candidate string correspondingly to each word and narrowing down words to a smaller number of words based on the frequency in this summing and discriminating coincident/nonconcident parts of characters to perform recollation of words. CONSTITUTION:Evaluation values which are given to characters coinciding with each candidate word are summed to a pertinent evaluation value table 12 by an evaluation value summing processing part 20, and the frequency in summing of the evaluation value for each word is counted and its value of the frequency in summing is stored in a summing frequency count totalizing table 15. A sort processing part 3 sorts candidate words obtained as the output of the evaluation value summing processing part 2 in the descending order of evaluation values, and the candidate word having the largest evaluation value is outputted as the collation output by a discrimination processing part 4. Thus, the number of candidate words as the object of recollation processing is reduced to increase the processing speed.

Abstract: PURPOSE:To decrease change with time of the discharge current from an output capacitor by decreasing the level of an output line to a set voltage being smaller than the high potential power voltage VDD and higher than vOH when the output line potential is the potential VOH guaranteed as a high logic output. CONSTITUTION:Suppose that an integrated circuit is accessed at a prescribed time T11, then a switch drive pulse signal is applied to a node N4 for times T12-T13 and an N-channel TR TN is turned on. A voltage 2.5V slightly higher than three times the threshold voltage appears at N TRs TN1-TN3 of a constant voltage circuit 15 as a constant voltage output. Then the voltage at a node N3 is decreased gradually up to 2.5V, but since the voltage is higher than a VOH potential, the other semiconductor 10 sense it as 1. At a time T14 when an actual is outputted, since the output voltage is already at 2.5V, the other device 10 senses it as the output of 0 data by having only to change the voltage by 1.7V till 0.8V. Thus, even if the output voltage is lowered at a slow speed, the output elay is unchanged and no care for malfunction is caused.

Abstract: PURPOSE: To reduce concentrations of NOx and CO in an exhaust gas without the use of any reducing catalyst by adjusting the ratio of an oxidizing agent in an combustion chamber so as to decrease the concentration of NOx in the exhaust gas to an allowable value and causing the activity of an oxidizing catalyst carried in a heat accumulating body to oxidize CO. CONSTITUTION: A through hole 1a, through which a burner nozzle 2 extends, is formed centrally in a heat accumulating body 1 which is secured to a wall portion of a combustion chamber to have a gas permeability. On the other hand, a cylindrical-shaped burner hood 3 is mounted on a side of the heat accumulating body 1 toward the combustion chamber or a high temperature side thereof. The heat of an exhaust gas discharged from the combustion chamber is accumulated in the heat accumulating body 1 to preheat an oxidizing agent supplied to the combustion chamber. In this case, the ratio of the oxidizing agent in the combustion chamber is adjusted so as to decreased the concentration of NOx in the exhaust gas to an allowable value. Then the heat accumulating body is made to carry an oxidizing catalyst to cause the activity of the oxidizing catalyst to oxidize CO in the exhaust gas.  Therefore, the concentration of CO is reduced to an allowable value.

Filed: 1989-11-10
Abstract: PURPOSE:To switch a test mode and a normal mode without adding any test pin by constituting a mode switching means by using only an existent clear terminal and a clock terminal. CONSTITUTION:When a CLK input is held at an earth potential in a period wherein the negative of CLR input is at the earth potential, D flip-flop 5 is reset and the S input of an R-S latch 4 falls to the earth potential; and then the Q output of the R-S latch 4 is held at the earth potential until the -CLR input varies from a source potential to the earth potential again. The above- mentioned mode is the normal mode and in this mode, the circuit operates as a 12-bit counter. In the test mode, on the other hand, the Q output of the R-S latch 4 is held at the source potential after the negative of CLR input varies from the earth potential to the source potential. When the Q output of the R-S latch 4 is at the source potential, a 4-bit counter 1 performs counting operation simultaneously. Then when the R1 input of the R-S latch 4 falls to the source potential, the Q output of the R-S latch 4 falls to the earth potential and the circuit shown in a figure operates as the normal 12-bit counter.

Abstract: PROBLEM TO BE SOLVED: To obtain stable developing characteristic against temperature fluctuation by performing control that the temperature of a high-resistance roller having little irregular resistance is kept constant. SOLUTION: A mixer 14 stirring and carrying toner (t), a supply roller 15 supplying the stirred and carried toner (t), and further a developing roller 4 functioning as a developing member supplying the supplied toner (t) to a photoreceptor 1 are disposed inside a developing device 11.

The temperature of the photoreceptor 1 rises by generated heat by a heater 5 and simultaneously the temperature of the roller 4 coming in contact with the photoreceptor 1 rises. A temperature sensor 6 detecting the temperature of a shaft 16 is attached to one end of the shaft 16, and output from the heater 5 of the photoreceptor 1 is controlled by a controller 7 according to a detection signal therefrom.  Thus, the ion conductive developing member whose resistance value becomes unstable is always used in stable temperature environment and the developing characteristic is stabilized.

Title: Method for controlling revolving speed of floppy disk
Inventor: SAKASHITA SHIGEO
IPC: G11B19/28
Filed: 1986-12-10
Abstract: PURPOSE:To reduce a read data error rate by controlling a disk revolving speed so that the data window signal is in synchronism with a reference frequency. CONSTITUTION:A read information signal 8 is inputted to a variable frequency oscillator (VFO circuit) 2 through the head output 1. A phase detector 4 compares the phase of a data window signal 9 outputted from the VFO 2 with that of a reference frequency 10 outputted from a reference oscillator 3. Then the signal 9 and the frequency 10 are integrated by an integration circuit 5 to undergo the conversion of voltage and amplified by an amplifier 6. Thus the revolving speed of a DC motor 7 is controlled. The frequency of the signal 8 is changed by said control of the revolving speed and therefore the frequency of the signal 9 is also changed. Thus the control value of the motor 7 is changed. In such a way, the pulse width of the signal 9 can be kept at a fixed level and the read data error factor is reduced.
