IPC: G09G3/36
Filed: 1989-01-25
Abstract: PURPOSE:To release the concentration of electric fields to an electrode edge part or electrode interval part and to remove a crosstalk, and to make a uniform display by forming picture element electrodes and counter electrodes in the recessed parts of substrates respectively. CONSTITUTION:Many 1st electrodes 12 and 2nd island-shaped electrodes which are connected to the 1st electrodes 12 through nonlinear resistance elements 11 are formed in the recessed parts 13 of a substrate 14. On the other hand, 3rd electrodes 17 as the counter electrodes are formed in the recessed parts 18 of a substrate 16. In a liquid crystal display device, a voltage which varies according to a display pattern is applied between picture element electrodes or counter signal electrodes and the liquid crystal of the electrode edge part performs nonuniform display operation, but a projection part of >=1mum is formed between adjacent electrodes, so the electric field concentration in liquid crystal is released to remove the crosstalk, thereby obtaining a uniform display state.

Title: Measuring apparatus for moisture content of grain in dryer
Inventor: HARUNA SHIGEAKI
IPC: G01N27/04
Filed: 1980-02-14
Abstract: PURPOSE:To reduce an influence of measuring irregularity and to improve measuring accuracy, by shortening operating period of moisture meter in case when measured value is abnormal and measuring again without waiting a normal measuring interval. CONSTITUTION:The computer C is connected to the moisture meter A. The data voltage Es of the meter A is converted into the measured moisture content Ms of digital quantity in the conversion part C1. Said moisture content Ms is compared with calculated moisture content up to the last time in the discriminating part C2 and when the moisture content Ms is smaller than the calculated moisture content, the calculted moisture content Msn of this time is computed by the operating part C3 from a prescribed related expression. In case of containing a high moisture such as green rice, abnormally higher value than that of measured value is sometimes obtained. At this time, the signal t3 shortening a working period, is outputted from the control part C5 and measurement is performed over again. When the value of Ms is smaller than that of the last Msn, the moisture content Msn of this time is computed as a normal value and is displayed on the display part B. Hereby, the measuring irregularity is eliminated and accuracy is improved.

Abstract: PURPOSE:To restrain the generation of bending of a filament, and obtain a stable FD dimension by welding the filament when it is subjected to an optimal load while changing a load continuously or in stages. CONSTITUTION:When a negative electrode body structure is manufactured, first of all, a load to be applied to a terminal 4 is changed continuously or in stages according to a wire diameter of the terminal 4, and is set at an optimal load for a cathode filament 3, that is, a load is applied to the terminal 4 in such a degree as not to cause bending in the filament 3, and the filament 3 is brought into close contact with a positioning jig 8. In this case, a driving shaft 11 is rotated by a motor 11, and a prescribed load is applied to the terminal 4 through a support lever 12 and pressure sensor 13. Thereby, since the bending is not caused in the filament 3, a stable FD (a distance up to the filament 3 from a surface of a focusing electrode 1) dimension is obtained. That is, since the filament is welded when it is subjected to the optimal load, assembling accuracy can be improved.

Title: Error diffusion processing device of display device
Inventor: ONODERA JUNICHI
IPC: G09G3/296
Filed: 1995-01-06
Abstract: PURPOSE: To make the switching noise inconspicuous especially at low levels in a pseudocontour preventing device which renews the brightness characteristics of luminescence for each frame to conduct error diffusion. CONSTITUTION: In a device which adds a reproduction error having occurred before the original pixel to a quantized and inputted original pixel image signal and obtains diffusion output signals to conduct pseudo half-tone display by an error diffusion circuit 11, the error diffusion circuit 11 applies error diffusion processing to the luminescence brightness characteristics of the quantity of brightness deviation at the levels excluding low levels renewed every moment by a brightness deviation calculating section 24 and that of the quantity of fixed brightness deviation preset by a fixed constant generating section 27 and outputs the results to the PDP. For this reason, even when the luminescence brightness characteristic varies depending on the data to be displayed, it is not forcibly adjusted to the typical luminescence characteristic.  Consequently it can adapt sufficiently to the gradation characteristic also for the data changing every moment and prevent generation of noise since a fixed constant is inputted at a low level.

Title: Viscous fluid coupling
Inventor: TAKAHASHI HIDEAKI
IPC: F16D35/02
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To ensure a desired pump function and form an outer peripheral face of a rotor simultaneously with the molding of the rotor by providing a plurality of projection parts on the outer peripheral face of the rotor and forming a side face of the projection in the direction of rotor rotation into a trapezoidal shape which is inclined from one face side which opposes to a projection on outer periphery of an operation chamber toward the direction of rotation of the rotor over the other face side thereof. SOLUTION: A plurality of projection parts 14b are formed continuously in the peripheral direction on an outer peripheral face of a rotor. The projection part 14b has a trapezoidal shape in which a side face in the direction of rotation of the rotor is inclined from one face side which opposes to a projection piece 13a toward the direction of rotation of the rotor over the other face side there. Consequently, sufficient rise of pressure is obtained due to the collision of viscous fluid against the projection piece 13a, and viscous fluid is discharged into a storage chamber through a through hole 13b so that a desired pump function is obtained due to a pump mechanism.  Since the trapezoidal projection part 14b does not obstruct the removal of dies when the rotor is molded by die casting by using a metallic material such as aluminum, it does not necessitate post-machining and can be molded simultaneously when the rotor is molded.

CONSTITUTION:A signal whose phase of a carrier is deviated by a prescribed value is outputted from a clock synchronizing device 7 in a relay station, the signal is inputted to a semiconductor switch 13 through a phase shifter 10 and an attenuator 11, applied to a local oscillator of a transmitter 4, where frequency modulation is applied. Furthermore, an interrupt control signal inserted in the relay station compares a carrier from a host terminal station outputted to an FM demodulator 6 of the relay station being the subsequent station with the carrier from the relay station, the carrier modulated by the local oscillator of the transmitter 4 of the relay station is adjusted by the phase shifter 10 and the attenuator 11 in the same level in opposite phase with no signal given thereto. Thus, biphase modulation waves opposite to each other in a given time slot are formed, the establishment of carrier synchronization is not required and a control signal is sent at a high speed.

Title: Fm transmitter-receiver
Inventor: KASUGA OSAMU
IPC: H04B1/50
Filed: 1988-01-29
Abstract: PURPOSE:To reduce the cost of a whole system by highly stabilizing the trans mission frequency of plural slave radio stations by accompanying the high stabilization of the transmitting frequency of a master radio station. CONSTITUTION:An FM signal fR, whose central frequency is enough highly stable, to be received from the master radio station through an antenna 7 is mixed with the output signal fL of a local oscillator 11 by a mixer 10 and goes to an IF signal. The IF signal fIF is demodulated by an FM demodulator 14 and outputted to an output terminal 2. Next, a base band signal to be input ted from an input terminal 1 is modulated by an FM modulator 3 and transmit ted from the antenna 7 as a transmission frequency fT. On the other hand, the base band signal is mixed with the receiving signal fR by the mixer 10 and inputted to an FM detector 15 as an ¦fT-fR¦. Then, the signal is passed through a direct current amplifier 16 and added to the bias terminal of the FM modulator 3 so that the error component of the fT can be removed. Thus, since the transmission frequency can be stabilized by utilizing a sufficiently stable receiving frequency from the master radio station, the cost rationalization of the whole system can be contrived.
