Title: Liquid crystal display device
Inventor: MATSUMOTO TOSHIO
IPC: G09G3/36
Filed: 1989-11-30
Abstract: PURPOSE:To improve vertical resolution and to prevent flicker from being generated by inverting a polarity for every two fields concerning a video signal to be supplied to a data signal line and applying the signal to the data signal line while further changing the polarity for each horizontal scanning period as well. CONSTITUTION:A polarity inversion reference signal generating circuit is provided in a timing control circuit 12 so as to output an inversion reference signal to a polarity inversion timing control signal line 17 and to control the operation of a video signal polarity inverting circuit 11. A flip-flop 22 divides the frequency of a horizontal synchronizing signal and outputs a signal inverting the polarity for each horizontal scanning period. Parts 23 and 24 twice divide the frequency of the vertical synchronizing signal and output the signal inverting the polarity for each frame. These two signals are inputted to an exclusive OR gate 25 and the signal inverting the polarity for each horizontal scanning period and each frame can be obtained. Thus, a required data signal can be obtained on a data signal line 7 and a picture can be displayed without flicker.

IPC: H04W52/02
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce the current consumption in an area in which a public mode is in-zone and a private mode is out-zone. SOLUTION: A mobile terminal 1 discriminates a mode where a terminal 1 itself is placed (step S21), and in a simultaneous wait mode, whether or not the public mode is in-zone is discriminated (step S22), and when the public mode is an in-zone, the retrieval of the private mode is proceeded (step S23).

Title: Digital timing discriminator and method for discrimination of frequency
Inventor: BEERUUZU ABUDEI
IPC: H03K5/26
Filed: 1991-11-05
Abstract: PURPOSE: To detect the frequency of a data input signal with a superior precision by monitoring a counted value for a prescribed frequency threshold. CONSTITUTION: The operation of a frequency discriminator circuit 10 gives a logical '1' output signal in an output 46, if the frequency of the data input signal applied to an input 12 is higher than a prescribed frequency threshold. The prescribed frequency threshold is determined by the frequency of a reference signal applied to an input 28 and the counted value monitored by decoding circuits 32 and 34. The output signal in the output 46 goes to logical '0', when the frequency of the data input signal is made lower than the frequency threshold. That is, the output signal is kept in the first logical state to indicate that the frequency of the data input signal is higher than the prescribed frequency threshold, if the counted value is reset by the data input signal before reaching a prescribed value. The signal is switched to a second logical state to indicate that the frequency of the data input signal is lower than the prescribed frequency threshold, if the counted value reaches the prescribed counted value before a reception of the reset signal.

Title: Optical disk
Inventor: TODE YUKARI
IPC: G11B7/2405
Filed: 1990-11-19
Abstract: PURPOSE:To obtain an excellent warpage preventing effect by forming a warpage preventing film having special x indicated by SiNx on an opposite side surface of a board to the surface formed with a recording film. CONSTITUTION:An SiN1.1 enhancement layer 2, a TbFeCo magnetic layer 3, an SiN1.1 protective layer 4, an epoxy resin protective layer 5 and an SiN1.1 dielectric protective layer 6 are sequentially laminated. Thus, when a warpage preventive film in which x indicated by the SiNx satisfies x < 4/3, is formed on an opposite side surface to a recording film, a film having an expansion coefficient equivalent to that of the recording film is formed on the surface of a board opposite to the recording film, and a symmetrical structure is formed at both sides of the board. Thus, even if environmental temperature is varied and thermal expansions occur, phenomena occurring at both sides of the board are equivalent, the variations cancel each other to prevent warpage deformation of a disk.

Title: Treatment of wastewater from paper manufacturing
Inventor: HATANO HITOSHI
IPC: C02F1/56
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To make treated water reusable and lower the load of the wastewater treatment thereafter by using a chelating polymer flocculant of maceration and steam maceration wastewater in paper manufacturing process and adjusting the wastewater neutral or acidic. SOLUTION: After waste paper 6 is macerated by a macerator 1, a chelating polymer flocculant 2 is added to control pH at neutral or lower. In this case, the addition amount is preferably controlled to adjust the pH around 6. After that, the resultant macerated waste paper is washed in a concentrated wastewater washing apparatus (a thickener) 3 and divided to a paper manufacturing substance 4 and washing wastewater 5. By such treatment, COD and BD in the wastewater are significantly lowered and pH adjustment is made unnecessary and the SS and the COD values in the separated water is remarkably decreased and flocculation and precipitation treatment is easily carried out, so that repeat use of the treated water is made possible. Further, dewatering efficiency of cellulose is greatly increased and recovery efficiency is heightened. Furthermore, PVA is made reusable.  As the chelating polymer flocculant 2, a mixture of a chlorine type inorganic flocculant and a polyamine type flocculant is especially preferable.

Abstract: PROBLEM TO BE SOLVED: To obtain a product having a pattern with variegated gradations in a natural matter such as a marble-like pattern or the like by a method wherein a cellulose-based powdered or granular material-containing thermoplastic resin composition is heated so as to thermally discolor its surface and then compression-molded. SOLUTION: A cellulose-based powdered or granular material-containing thermoplastic resin composition is plasticized and charged in lumps in some part in an open mold. Next, further, the thermoplastic resin composition is charged in lumps in another part in the same mold. After an arbitrary number of times of the operations just mentioned above are repeated, heating temperature and hour are held until the color of the surface of the thermoplastic resin composition changes. Next, the resultant composition is pressed so as to form a molding. The cellulose-based powdered or granular material-containing thermoplastic resin composition may well be a resin having two or more colors in advance. After sheets individually made of respective single colors are formed and thermally discolored, the sheets are piled up and compression-molded so as to allow to manufacture a molding.

IPC: F41F3/04
Filed: 1987-12-15
Abstract: PURPOSE: To simplify the entire mechanism constitution, without needing a special power source, and execute an efficient opening operation with a min. propelling force by constituting so as to obtain a force required for opening a front cap from the propelling force of an airframe. CONSTITUTION: When an airframe is launched from a still state by a launching instruction, a protrusion 5 on the airframe pushes one end of an acting force output mechanism 6 as shown by arrow A, thereby the acting force output mechanism 6 rotates counterclockwise to pull an acting force transmission mechanism 7 coupled with the other end of the acting force output mechanism 6 as shown by arrow B, and a lever of an opening operation mechanism 8 turns to open a front cap 9. Since the force for opening the front cap 9 is obtd. from the propelling force of the airframe, any special power source is not needed and the entire mechanism constitution can be simplified. The propelling force converted to an acting force of an effective varying pattern according to the load curve during icing or freezing is taken out, an efficient opening operation can be made by a min. propelling force.
