Title: Method for driving liquid crystal element
Inventor: NOGUCHI KOJI
IPC: G09G3/36
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent a frame frequency from lowering and to prevent a display from becoming dark. SOLUTION: When an active matrix type liquid crystal panel P is driven, a picture is displayed by applying a gate voltage Vg to the gate electrode 5a of a TFT 5 for every frame and also by applying a write voltage +VD or -VD to the source electrode 5b of the FTF 5. Then, the frame frequency is prevented from lowering and the display is prevented from becoming dark by performing such a display without applying a reset voltage to the panel P.

Title: Japanese language word processor
Inventor: YAMAZAKI MIKIHIKO
IPC: G06F17/21
Filed: 1987-10-26
Abstract: PURPOSE:To relax limitation on activity environment and to easily generate a document in Japanese language by using a word processor input device only to store data before being KANA (Japanese syllabary)-KANJI (Chinese character)-converted on a storage part being set loadably/unloadably freely. CONSTITUTION:The storage part 3 is loaded on an input device 20, and a sentence desired to be generated is inputted sequentially by using a keyboard 1. At this time, a control part 4 performs control to monitor-display key input information from the keyboard 1 on a display unit 2 and the control to store the data before KANA-KANJI conversion generated according to the key input information. Therefore, it follows that the data before applying the KANA- KANJI conversion is stored in the storage part 3. In such a way, it is possible to miniaturize a portable word processor input device to the one carried by a single hand, and to input the sentence thought in a car or on a road at that time and at that place, and to relax the limitation on the activity environment of the word processor.

Title: Driving method of ferroelectric liquid crystal cell
Inventor: KAWAGISHI HIDEYUKI
IPC: G09G3/18
Filed: 1986-11-14
Abstract: PURPOSE:To prevent a ferroelectric liquid crystal cell from deterioration of bistability by impressing an electric field having the same intensity as the reverse electric field due to the spontaneous polarization of the liquid crystal molecule on the opposite direction from outside in the nondisplay stage of the ferroelectric liquid crystal cell. CONSTITUTION:Two substrates 11 having each two pairs of electrodes 12 and orientation film 13 are laid to face oppositely to each other. During this stage, a liquid crystal cell is constructed by packing ferroelectric liquid crystals 14 having the axes or orientation almost same in the stage of impressing electric field and in the stage of nonimpressing the electric field. An electric field V0 having almost equal intensity to the reverse electric field 16 but directing toward opposite direction to each other is applied for the purpose of eliminating the reverse electric field 16 due to the spontaneous polarization 15 of the liquid crystal molecule in the stage of nondisplay of the cell. By this method, adverse effect on the liquid crystal molecule is prevented by eliminating uneven distribution of ions in the nondisplay stage. Since the electric voltage is impressed from outside, deterioration of the difference of threshold value and bistability are prevented even if the cell is allowed to stand for a long time.

Abstract: PURPOSE:To reduce the man-hour for adjustment by controlling a phase inver sion circuit by the detected phase difference of a phase difference detecting circuit and setting the output potential of a comparator at the positive or nega tive potential in accordance with the detected phase difference. CONSTITUTION:The signals L+R and L-R received by a radar antenna are respectively dropped by the 1st and 2nd mixer circuits 1 and 2, are amplified by the 1st IF circuits 3 and 4, are dropped again by the 2nd mixer circuits 5 and 6, are amplified by the prescribed rate by the 2nd IF circuits 7 and 8 and are respectively detected 11 and 12. The two detected 11, 12 signals are compared 10 of the level thereof by which the level difference is detected and outputted 13. On the other hand, the output signals of the circuits 1 and 2 are respectively brought to the specified levels by limiter circuits 14 and 15 and the phase difference of both signals is detected 16. A circuit 13 is so operated that the output signal of the circuit 10 attains negative potential when the detected phase difference is advanced than the phase of the detected 16 signal of the L antanna and attains positive potential in the opposite case. The level difference signal of the angle difference is thus controlled to the negative or positive potential by which the direction is obtd.

Title: Xerographic apparatus with non-friction type cleaner
Inventor: UIRIAMU ERU GOOFU
IPC: G03G21/10
Filed: 1989-10-17
Abstract: PURPOSE: To remove residual toner by small frictional force by driving a cleaning member so that electric field may be generated on a charge holding surface, separating the residual toner from the charge holding surface and forming toner cloud. CONSTITUTION: A conductive cleaning member 102 is adjacently arranged to cross the charge holding surface, and the AC voltage 108 of selected frequency is impressed on the member 102 in order to generate the alternating electric field on the edge 106 of a blade adjacent to the charge holding surface. The toner near to the member 102 forms the toner cloud jumping from the charge holding surface and vibrated in accordance with the generated electric field. Since the toner fiercely shaken causes much collision between toner particles so as to shake the toner held on the surface, the removal of the toner from the surface is much more accelerated. Then, the toner held on the surface is electrostatically and mechanically removed. The life of the cleaning device with AC bias prolonged because of slight surface contact.

Title: Semiconductor device and its manufacture
Inventor: MURAKAMI TOMOYASU
IPC: H01L23/522
Filed: 1991-10-18
Abstract: PURPOSE:To enable a contact resistance between a diffusion layer which is formed on a semiconductor substrate and a wiring metal to be reduced. CONSTITUTION:A first n-type diffusion layer 5 is formed on a silicon substrate, an insulation film 2 is deposited, and then a connection hole 3 is provided on the first n-type diffusion layer 5. Then, a polycrystalline silicon 7 with recessed and projecting parts is deposited on the first n-type diffusion layer 5 and then the recessed and projecting parts are formed on the first n-type diffusion layer by performing etching simultaneously on the polycrystalline silicon 7 and one portion of the first n-type diffusion layer 5. Further, an ion 9 such as arsenic ion is ion-implanted to a substrate at a proper angle, thus enabling the second n-type diffusion layer 8 to be formed. After this, a metal wiring layer 4 is formed by the sputtering method etc. By forming recessed and projecting parts on a surface of the diffusion layer, a contact area between the diffusion layer and the metal wiring layer is increased and the contact resistance can be reduced. Also, by forming the second n-type diffusion layer, breakdown of a junction due to thinning of the first n-type diffusion layer can be prevented.

Title: Logical gate drive control circuit
Inventor: ISHII TOSHIO
IPC: H03K19/086
Filed: 1986-11-14
Abstract: PURPOSE:To prevent thermal runaway of an ECL logical gate circuit by providing a temperature response circuit so as to decrease a control potential of a transistor (TR) applying constant voltage drive to a constant current TR being a component of an ECL logical gate circuit at a specific temperature or over. CONSTITUTION:Since no current flows to the temperature response circuit 3 through a resistor R4 from a high potential power supply Vcc of the bias circuit 2, the bias circuit 2 acts like a conventional constant voltage generating circuit to control the current flowing through the constant current TR Q4 of the ECL logical gate circuit 1 so as to keep the output amplitude constant. On the other hand, if the operating temperature rises abnormally to, e.g., 150 deg.C, the bias current drive TR Q4 is turned off by the operation of the temperature response circuit 3 and the output voltage of the bias circuit 2 is decreased. Thus, the gate current flowing to the constant current TR QG4 of the ECL logical gate circuit 1 is zero and the total current of the ECL logical gate circuit 1 is decreased.
