Filed: 1994-04-20
Abstract: PURPOSE:To suppress unnecessary radiation from the liquid crystal display device by providing a liquid crystal panel with metallic films or conductive films along some or all of the respective peripheral sides. CONSTITUTION:A lower glass substrate 5 and a source driver TCP 2 as an IC for liquid crystal driving are connected to the liquid crystal panel 1a, and this source driver TCP 2 and the connection part of the lower glass substrate 5 have the metallic films 6 for shielding formed on the opposite-side surface of a substrate where a reverse polarizing plate 8 is present.

Title: Method of feeding synthetic fiber yarn to rotary nip roller
Inventor: IMAIZUMI TAKASHI
IPC: B65H51/32
Filed: 1984-04-24
Abstract: PURPOSE:To remarkably reduce the generation of wear of a rotary nip roller by setting the traverse of one cycle as a traverse diagram having a large peak and a small peak. CONSTITUTION:A traverse diagram having at least two kinds of amplitudes, large peak and small peak is incorporated in a cam. Therefore, the conventional eccentric cam is combined to suitably select the diagram. These two diagrams are alternately conducted, so that the turn portions of the large peaks are intermittent to remarkably reduce the occurrence of wear of the turn portions. In case of traversing a yarn on entry side of a rotary nip roller in the axial direction of the rotary nip roller, the yarn is shifted for the traverse width at substantially equal intervals on the roller, so that the wear of the nip rubber roller 9 is uniform laterally. Thus, the wear can be remarkably reduced as compared with the conventional method using fixed cycle.

Abstract: PURPOSE:To improve the controllability of a threshold voltage value, by forming a P-base and an N<+> source with a nitride film as a mask, thereafter removing the nitride film, and implanting ions in the entire surface or in only a part of the place, where the nitride film has been located. CONSTITUTION:On a semiconductor substrate 1, an oxide film 2 and a nitride film 3 are grown. Patterning is performed by a photolithography technology using resist 4. Thereafter, with the nitride film 3 as a mask, an impurity region 5, whose conductivity type is reverse with respect to that of the semiconductor substrate and an impurity region 6 having the same conductivity as that of the semiconductor substrate are formed. At a part beneath the nitride film 3, which is oxidized with the nitride film 3 as a mask, an oxide film is not grown. Therefore, a recess shape (bird's beak) is formed. Then, the nitride film 3 is removed. An impurity region 15, whose conductivity is reverse with respect to the substrate is formed on the entire part or a part of the place, where the nitride film has been located. Then, a gate electrode 8, a source elecrtrode 13 and a drain electrode 11 are formed sequentially, and a vertical type field effect transistor is formed. Since the threshold voltage value can be determined by the impurity region 15, control accuracy is improved.

Title: Combustion sensing device
Inventor: MORI KEIICHI
IPC: F23N5/12
Filed: 1985-04-18
Abstract: PURPOSE:To enable a positive sensing of a deterioration of insulation of flame rod sensor by a method wherein AC voltage is applied across the electrodes of the flame rod sensor, an electric current in a resistor connected in series with the flame rod sensor is measured by an electric current measuring circuit, and in the electric current measuring circuit, an electric current value is measured when a voltage is applied to the flame rod sensor in a positive direction and a loading direction in synchronism with AC voltage. CONSTITUTION:An electric current If+ of a flame ion current If flowing in a flame rod sensor 10 in a positive direction shows a variation in response to a state of combustion in a burner. The electric current If- in a negative direction normally shows a quite low value due to a characteristic of smoothing characteristic of the flame. However, when its insulating characteristic is deteriorated due to an adhesion of carbon, etc. to the flame rod 12, the valve of If- will be increased. An output lg from a calculation amplifier 16 is made such that the electric current If is converted to a voltage value from a minus potential of DC power supply 17 in cynchronism with a switching AC voltage lAC. The potential lg is varied in response to a state of combustion and a controller may perform various controls. The value lg- corresponding to the electric current If- is increased due to a deterioration in insulation of the flame rod sensor 10 and then a negative current sensing circuit 20 may determine the deterioration of insulation.

Title: Multiplier
Inventor: NAKAGAWA TATSUO
IPC: H03K5/00
Filed: 1989-03-31
Abstract: PURPOSE:To double an input clock frequency by taking an exclusive OR between an input clock and a retarded clock through the control of the delay quantity. CONSTITUTION:Assuming a pulse width of an input clock 10 as '4' and a clock delay means 1 retards a half of the input clock with a delay amount 3. When the delay is too small, since the delay of the retarded clock 20 is '1' with respect to the pulse width 4, the output clock 30 of an EX-OR gate has a duty ratio <=50%. Thus, the width of a pulse width signal is 6 with respect to the pulse width 4 of a pulse width signal 50, a comparison means 7 outputs a signal 90 whose delay is '-1' and an output 100 whose delay is '2' of a delay quantity latch means 8 is corrected into a correct delay '3'. When the delay is too much, the duty factor of the clock 30 is <=50% with a delay '3' of the clock 20 with respect to the width '4' of the clock 10, the means 7 outputs a signal 90 whose delay is '+1' and the output 100 whose delay is '4' is corrected into a delay '3'. Thus, the clock whose duty factor is 50% is obtained with a frequency twice the input clock frequency.
