Title: Electron emission element and manufacture thereof
Inventor: SAITO NOBUYUKI
IPC: H01J9/02
Filed: 1988-08-24
Abstract: PURPOSE:To reduce variations in characteristic, control the shape of an element, and prolong element-life by changing the density distribution of fine grains of a high resistance part in the direction of opposed electrodes. CONSTITUTION:Electrodes 1 and 2 consisting of a low resistor for application of voltages are provided on an insulating material such as glass, quartz, etc., spaced a micro-interval apart, and fine grains 6 are formed as an electron emission part between the electrodes so that the grains have the density distribution in the direction between the opposed electrodes. In this instance, the fine grains 6 are some 10Angstrom -some mum in diameter, and the interval between each fine grain is formed in the range from some 10Angstrom to 2mum. An electron emission element is manufactured by electrically charging the fine grains 6 came flying on the element and depositing the fine grains while electrical potential whose positive or negative value is equal to that of the fine grains is applied to the electrodes 1, 2. There is thus no need for performing forming treatment.

Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To obtain a unit for recovering an ink jet head clogged with ink which is applicable to oil ink without requiring any check valve or one way clutch. SOLUTION: Driving force is transmitted from a drive source 1 such that an ink suction pump is engaged with a pump drive gear 6 to perform suction in response to the rotation of a paper feed roller (drive source) 1 in the first direction. Planetary gear mechanisms 2, 3 are disengaged from the pump drive gear 6 in response to the rotation of the drive source 1 in the second direction. The passage between an ink reservoir 11 and an ink discharge tank 15 is interrupted to enclose the ink sump 11 while being interlocked with the engagement of the planetary gear mechanisms 2, 3 and the pump drive gear 6. The passage between the ink reservoir 11 and the ink discharge tank 15 is then opened while being interlocked with the disengagement of the planetary gear mechanism and the pump drive gear 6 and the ink is fed from the ink sump to the discharge ink tank.

Abstract: PURPOSE:To attain reproduction surely in response to characteristics by using a frequency of a synchronizing signal in an FM luminance signal recorded at each recording standard to discriminate the standards of recording thereby switching automatically the characteristics of a reproducing signal processing system and omitting the operation for each recording standard. CONSTITUTION:A reproducing video signal (a) is fed to a filter 24 set so that a synchronizing signal subjected to FM modulation in the video signal of a recording standard passes through from an input terminal 21, a synchronizing signal (b) is separated and rectified by a rectifier circuit 25. Portions other than the synchronizing signal portion are excluded by using the same frequency as the synchronizing signal (b) to supply the synchronizing signal (d) from an input terminal 22 to a gate 26 as a gate pulse thereby driving an FF27. A head switching signal (f) is applied to a reset pulse generating circuit 28 from an input terminal 23 to reset the FF27 at each field.

Title: Solid-state image sensing device
Inventor: MAEDA HIDEO
IPC: H04N5/355
Filed: 1987-08-24
Abstract: PURPOSE:To prevent the output of a false signal a by excess charges, to expand the degree of freedom of signal reading timing and to attain the ease of the variation of characteristics by directly joining a channel region and a common region and forming a transfer path for storage charges in an SIT. CONSTITUTION:An SIT 118 is composed of a source SA in an N<+> region, a storage gate GA for a P<+> region 112 and drains DA in N<+> regions 106, 108, and connected respectively to electrodes TSA, TGA and TDA as mentioned above. On the other hand, a current path shown by the arrow FA by an opening 116 for the drains DA is represented by a P-N-P transistor 120. Consequently, the excess storage of charges to a gate for the SIT is prevented even when there is light incidence more than the quantity of light saturated by shaping the discharge path FA for storage charges in the SIT 118, thus obviating the output of a false signal from the SIT by excess charges. One part of charges toward the gate for the SIT is discharged by applying proper bias voltage to the main electrode side of such an equivalent transistor, thus varying photoelectric transfer characteristics.
