Title: Display quality improving circuit for liquid crystal display
Inventor: YOKOYAMA KOZO
IPC: G09G3/36
Filed: 1990-03-09
Abstract: PURPOSE:To improve a defect in display quality due to the distortion of a driving waveform by using the output of an exclusive OR gate as a liquid crystal AC signal, repeating AC generation at intervals of plural common lines, and inverting the polarity of each frame signal alternately. CONSTITUTION:A segment driver latch signal LP is inverted by an inverter INV1 to activate the clock input terminal CK of a 1/N frequency dividing circuit 3. Further, the carry output terminal CY is inverted by an inverter INV2 and connected to a load terminal -LD to form a frequency dividing circuit which has an optional frequency division ratio. The output signal T2 of a flip- flop circuit is inputted to one terminal of an exclusive OR gate 6 and inverted and uninverted repeatedly with the liquid crystal AC signal DF connected to the other terminal to obtain an improved liquid crystal AC signal M. Further, the liquid crystal AC signal M is inverted in polarity at intervals of plural common lines and at intervals of a frame in one frame. Consequently, the defect in display quality such as a ghost is improved.

Title: Excavation controller for hydraulic shovel
Inventor: KAKUZEN MAKOTO
IPC: E02F9/20
Filed: 1991-03-22
Abstract: PURPOSE:To effectively improve controlling accuracy by controlling the drive means of an object for control out of a boom, arm and bucket so that the bucket may move keeping a relation to the face to be excavated constant in a hydraulic shovel provided with drive means of the boom, arm and bucket. CONSTITUTION:The weighing factor corresponding to the number of count of the control synchronization from the start of control is memorized in a weighing factor multiplication section 36, and the read in control deviation is multiplied by the weighing factor corresponding to the point of time of reading in, and the value obtained by this multiplication is set as a learned value. In the next step, the sum of the accumulated value of the past learned value and the learned value set by the multiplication section 36 is memorized in a memory controller 37 as a new accumulated value, and the accumulated value corresponding to the number of count, which is the sum of the number of count of control frequency and the number of time shift, is output as basic value of the quantity of learning control. By this constitution, memory capacity required for learning control can be saved keeping control accuracy high and the device cost can be reduced.

Title: Transverse electric field system active matrix type liquid crystal display device
Inventor: ANDO MASAHIKO
IPC: G02F1/136
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to avoid charge accumulation and to assure good image quality, by using holding capacitor parts having a reversible charge accumulation characteristic. SOLUTION: The holding capacitor part 112 is formed as the structure obtd. by holding a first gate insulating layer 13 as an insulating layer for a capacitor consisting of a silicon nitride film with a source electrode 18 as a source electrode for the capacitor and a gate electrode 12 as a gate executed for the capacitor. If the holding capacitor part is constituted in such a manner, the barrier effect of a second gate insulating layer 14 consisting of a silicon oxide film disappears and, therefore, the electrons implanted into the silicon nitride film (the first gate insulating layer 13) return to the semiconductor layer 15 (including drain electrode 17 and source electrode 18) side when the threshold control voltage attains zero and the charge accumulation in the holding capacitor part 112 is averted.  Accordingly, since the internal voltage occurring in the charge accumulation is no longer impressed on liquid crystals, the image defects, such as flicker and after-images, do not arise any more.

Title: Continuous suppression system for same sign
Inventor: KATOU MASAMI
IPC: H04L25/49
Filed: 1981-04-20
Abstract: PURPOSE:To prevent an output of an alarm in error by a repeater, by inserting an auxiliary code to a specific bit out of a plurality of bits if a plurality of bits of the same sign are consecutive for a prescribed number. CONSTITUTION:An excessive pulse generated by speed conversion of (n+1) to (n) to an input pulse is taken as X-bit. The input pulse is given to a memory 3 and read out in a frequency of n/(n+1) times of a clock frequency (n) of the input pulse. The X-bit is inserted to a timing position of the excessive pulse obtained in this step. The inserted X-bit is made at an inverter 5 for the opposite sign of the pulse of the n-th bit of the input pulse train. As a result, since the number of consecutive pulses of the same sign can be suppressed to (n+1) or lower, the reliability of lines is improved.

Title: Electrophotographic printer
Inventor: MIYAZAKI TORU
IPC: G03G15/00
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To maintain stable transfer performance even for a long-time printing and to realize a high-quality printing by previously measuring the changes in resistance with respect to time of a transfer circuit including a transfer roller. SOLUTION: A constant current is supplied to a transfer roller 5 from a constant current control part 13 for a fixed time before using a printer. A control part 10 measures the changes in resistance with respect to time of a transfer circuit at such a time and stores it. When transfer is actually started, a constant voltage control part 14 controls its voltage so that the changes in the resistance with respect time of the transfer circuit may be canceled. Thus, the transfer voltage of the transfer roller whose resistance changes with respect to time is stabilized and printing quality is improved.

Title: Memory control system
Inventor: KOJIMA KAZUNORI
IPC: G06F12/16
Filed: 1986-03-20
Abstract: PURPOSE:To eliminate the need for an adder circuit and to miniaturize a circuit by determining a memory board to send the timing signal of a memory based upon the capacity information of plural memory boards, the unloaded information and the designated address information. CONSTITUTION:From respective slots 1-3 to a timing control circuit 4, respective capacity information C1-C3 are inputted through pulled-up signal lines S1-S3. Consequently, even when any slot is empty and unloaded information '11' is inputted to the timing control circuit 4, therefore, a timing signal is not sent to a pertinent empty slot. Since from the loaded slot to which a memory board is inserted, the capacity information of either of '00', '10' and '01 is inputted to the timing control circuit 4, by having the meaning to the capacity information, an actual capacity is found and the timing signal is sent to the pertinent slot. Thus, an adder circuit is unnecessary and a circuit is miniaturized.

Abstract: PURPOSE:To improve efficiency in working such as a data inputting work and a data referring work, etc., by ranking plural menus which are going to be used in order of use frequency from highest one and sequentially arranging them from a first screen in order of use frequency from the highest one. CONSTITUTION:The rank of use frequency of the respective menus which are going to be used for the next working is previously decided and an operator inputs 'next working use frequency rank', for example, in order such as 8, 1, 4-9, 3 from upper order by operating numerical keys. After inputting the data of use frequency rank of the respective menus in a parameter file 19, the menus are set on a menu display field 9, for example, shown like figure by operating the command keys. Now the parameter file 19 disappears from a CRT screen 11 and it is stored in an NC device 3. Thus, four menus having higher use frequency, for example, the menus B, G, L and C are arranged on the first screen in order and four menus having next higher use frequency, for example, I, E, J and A are arranged on the second screen in order, moreover the menus K, D, H and F are arranged in order on the third screen.
