Title: Semiconductor memory device
Inventor: KIHARA YUJI
IPC: G11C11/41
Filed: 1988-12-09
Abstract: PURPOSE:To quickly activate a word line by giving an activating signal to divided word line means through a transmission gate means. CONSTITUTION:When a word line WL00 is activated, a preword line RGSL is set to the high level by a row decoder 3. A signal B0X0 in the high level and a signal, the inverse of B0X0 in the low level are given to a transmission gate 15, and the gate 15 is turned on. The line WL00 is set to the high level through the gate 15 by the voltage from the RGSL. The voltage level of a word line signal is given to the line WL00 without the loss. Consequently, the driving capability of a memory cell is satisfactorily displayed. The voltage rise speed of the line WL00 is not reduced. Since one line RGSL has lines WL00 and WL01, the total sum of parasitic capacity between the line RGSL and a bit line 10 is equal to (the total number of word line) X C X 1/2 to prevent a bad influence due to the parasitic capacity. Thus, divided word line means are quickly activated.

Inventor: NAKANO YOSHIAKI
IPC: B23K9/038
Filed: 1991-11-27
Abstract: PURPOSE:To provide the one-side butt welding method of deformed bars capable of welding deformed bars even in a narrow place where the direction to insert a welding wire into groove space is limited to the specific direction and maintaining specific strength even when defects are caused on a rear side part for the welding wire insertion port side. CONSTITUTION:In the welding wire insertion port side, weld metal 3a is built-up in the area between horizontal ribs nearest from the groove face of respective deformed bars 1a and 1b. In this case, the weld metal 3a is built-up higher than the horizontal ribs 2 in the area more than 1/4 of the outer circumference of the bar 3. Even when the defects such as undercuts and overlaps are caused, rupture due to stress concentration can be avoided. As a result, it is not necessary to cut off and rework a joint when the defects are caused and welding work and designing of arrangement of bars are facilitated.

Filed: 1989-12-01
Abstract: PURPOSE:To prevent a sense of displeasure given to an operator and the acquisition of an undersired line by restoring forcibly the line when a fault takes place in a power supply of a facsimile equipment during facsimile reception. CONSTITUTION:When a power failure such as interruption of power supply of a facsimile equipment 40 or a power output decrease to a level at which the equipment 40 is not normally operated takes place, the abnormality in a power unit is detected by a power supply output detector 34 via a FAX interface 33 and the result is informed to control section 32.

Title: Recognition apparatus with voice response
Inventor: KANEUCHI KUNIYASU
IPC: G10L15/04
Filed: 1987-12-10
Abstract: PURPOSE: To inform a speaker of misdetection and enable reregistration by indicating which voice section the misdetection is caused in when the difference in length between voice sections detected by two feature quantity extraction part is larger than a predetermined threshold value. CONSTITUTION: A voice for standard pattern generation when inputted to a microphone 11 is converted into an electric signal, which is inputted to the feature quantity extraction parts 12 and 13 respectively.

Filed: 1992-11-24
Abstract: PURPOSE:To make possible control with high accuracy even to a non-linear controlled system by defining identification signals as plural number of signals that all the range of controlled system are divided into plural points and performing a pseudo linear identification from control constant based on plural responses. CONSTITUTION:An indentification signal generation part 2 equally divides a space from the lowest static value to the highest static value of a controlled system into N intervals at a range being regarded as a linear and outputs very small identification signals to N identifying signals. Two degree of freedom PID constant determination part 3 calculates PID control constants corresponding to N identifying signals. The two degree of freedom PID determination part 3 compares the sizes of three control constants which are successively adjacent with each other of the PID control constant, eliminates the medium if the difference is within a prescribed range and determines the PID control constant at the further intermediate point when the difference is different, exceeding the prescribed range. A state quantum-PID constant conversion part 17 performs a state quantum/PID constant conversion. A PID constant interpolation part 18 converts plural control constants to an unequivocal curve for all the states of a process.
