IPC: G09G3/28
Filed: 1995-03-09
Abstract: PURPOSE: To provide the plasma display provided with a digitizer to be used for inputting picture information, etc., prevented from a burn-in phenomenon. CONSTITUTION: A pen coordinate signal S1 indicating the position on the digitizer 2 of a pen 1 is inputted to an integration circuit 4 via an amplifier 3 and is integrated to be made to be a pen coordinate signal S2, which is binarized in a Schmitt circuit 5. A re-triggerable monostable multivibrator (MM) 6 is triggered by the output S3 and when the cycle of the signal S3 is longer than a set time constant, the inverted output S4 becomes a logic 1. This output S4 is inputted to a MPU 7 and when the S4 is the logic 1, the MPU 7 outputs a display inversion signal S5 by regarding that a pen input is not present during a time longer than the period set in the re-triggerable MM 6. A video signal is inverted to be reverse-displayed on a display part 9 by controlling the inversion control circuit 8 of a plasma display by this signal 5.  Thus, the light emitting efficiency of the screen of the plasma display is averaged.

Title: Line decoder circuit for nonvolatile memory
Inventor: ATSUMI SHIGERU
IPC: G11C11/407
Filed: 1985-03-13
Abstract: PURPOSE:To reduce power consumption and to provide a high speed operation by impressing a word line selection signal-fi to the gate of a P-channel transistor for load. CONSTITUTION:In a line decoder circuit, the word line non-select state occurs in the following two cases: (1) the word line select signal fi is '0' and one of decoder select signals gi-gk is '0' and (2) the signal fi is '1' and all of the signals gi-gk are '1'. Also, in the word line select state, the signal fi is '0' and all of the signals gi-gk are '1'. In the word line select state, the P- channel transistor 15 is completely off, the direct current path is not formed resulting in saving in power consumption. In a NAND circuit 1, only the VDD side transistor is on when the output is '1', while only the VSS side transistor is on when the output is at '0' level so that the direct current path is not formed. Thus, power consumption is reduced while the high speed operation is also becomes possible.

IPC: C21C1/02
Filed: 1993-02-16
Abstract: PURPOSE:To obtain a low Si.low S.high Mn molten iron by executing smelting reduction to a Mn ore, increasing Mn concn. in the molten iron and progressing desiliconizing and desulfurizing reactions at the same time. CONSTITUTION:Into the high Si molten iron tapped from a blast furnace, lime is added at 4-10kg/ton of molten iron in a unit requirement from the upper part. Further, the mixed material of the lime and powdery Mn ore so as to be 2.5-4.0 basicity including the lime is blown into the molten metal together with carbonaceous material, and the smelting reduction of the Mn ore with Si in the molten iron is progressed at the same time of the desulfurizing treatment.

Title: Squirrel-cage induction synchronous motor
Inventor: MORIYAMA KAZUYOSHI
IPC: H02K19/14
Filed: 1987-03-06
Abstract: PURPOSE:To improve the synchronous characteristic and to increase the synchronizing torque of a squirrel-cage induction synchronous motor by narrowing a magnetic path of teeth of recess poles only at the part of the tooth corresponding to the inner slots of double squirrel-cage slots. CONSTITUTION:Double squirrel-cage slots 2, 2' are formed on the outer periphery of a rotor core 1, slits 3 are formed, and projecting and recess poles 4, 5 are formed. The slot 2' formed at the pole 5 is widely formed in width at the inside with respect to the slot 2 formed at the pole 4, thereby narrowing the width of the tooth 6 to narrow the magnetic path of this part. Thus, the difference of the magnetic resistance of the magnetic path 8 of the pole 5 from the magnetic path 6 of the pole 4 is increased to increase a synchronous torque. Since the magnetic flux passes the outer periphery to generate a torque at the conductor in the outer slot at the time of starting, the starting characteristic is not reduced thereby.
