Abstract: PURPOSE:To improve the lightness (brightness) by dividing a 4th grid of a CRT into two, prolonging an electron beam subject to electrostatic deflection striking on a fluorescent face and sampling and holding a video signal for the period. CONSTITUTION:A cathode ray tube 16 is provided with a couple of electrodes G4a, G4b able to control an electron beam 1 in the horizontal direction of a picture and position information detection means 27, 28 able to detect an electron beam radiation position, and a deflection voltage control means 24 controls an electrostatic deflection voltage supplied to a couple of electrodes G4a, G4b so as to allow the electron beam 1 to strike on prescribed fluorescent body faces R1, G1, B1 consecutively for a prescribed time. While the electron beam strikes on the fluorescent body faces R1, G1, B1 based on the detection output signal from a position information detection means 28, sample and hold means 13, 14, 22 hold the level of the inputted video signal. Thus, the time when the electron beam 1 strikes on a fluorescent body PC is prolonged and the brightness of the CRT for HDT is improved considerably without deteriorating the resolution.

Title: Image forming device
Inventor: ASHIBE TSUNENORI
IPC: G03G5/147
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To prevent the unevenness of an image at a wavy part and to prevent the tension member mark or the shrink mark of the finally obtained image by providing surface waviness having specified wavelength on the surface of an intermediate transfer drum and setting the average waveheight of the surface waviness to be equal to or under a specified value. SOLUTION: The average waveheight of the surface waviness of the surface of an intermediate transfer drum 30, that is, the surface waviness of the drum 30 having the surface waviness whose average wavelength is >=0.1mm and <3mm is set to <=10μm. Thus, the difference of distance that toner is moved from the surface of a photoreceptor drum 1 being a 1st image carrier to the drum 30 is reduced between the projected part and the recessed part of the waviness of the drum 30. Therefore, irregular transfer at the primary transfer time is reduced and the retransfer of the projected part at the second primary transfer time is eliminated, so that the tension member mark is reduced. Furthermore, faulty cleaning caused by the toner remaining in the recessed part after secondary transfer is reduced.

IPC: B60W10/10
Filed: 1987-06-02
Abstract: PURPOSE:To improve the durability of frictional engaging devices by providing a means of detecting whether a vehicle is traveling on a traffic-snarled road or not and a means of varying at least the gear-change point of shift-up from the first gear stage to the second gear stage of a gear-change map to the higher speed side at the time of traveling on a traffic-snarled road. CONSTITUTION:When a vehicle is judged to be traveling on a traffic-snarled road, at least the gear-change point of shift-up from the first-gear stage to the second-gear stage is varied to a higher speed side. As a result, the frequency of gear change between the first-gear stage and the second-gear stage during the traffic-snarled road traveling can be greatly reduced, improving maneuverability. And, further, since the frequency of gear change is reduced, the durability of frictional engaging devices can be naturally improved for that amount.

IPC: H05B41/32
Filed: 1980-10-03
Abstract: PURPOSE:To increase the accuracy of flash control and at the same time to reduce the effect to the flash duration, by invalidating the working of an impe dance element for suppression of discharge current after the lapse of a prescribed period from the start of flash. CONSTITUTION:When a trigger switch 12 is closed, a main SCR15 conducts via a capacitor 10. Then a flash tube 14 emits the light by the current discharged from a main capacitor 6. This current is suppressed by a coil 23 which is connected in sereis between the tube 14 and the capacitor 6 forming an impedance element, and as a result the flash light emission is controlled with high accuracy and with good rise. On the other hand, the Zener voltage is produced from a Zener diode 17 by the voltage induced from the coil 23. Then an SCR22 conducts via a delaying circuit comprising a resistance 18 and a capacitor 20 and after the lapse of a prescribed period from the start of flash. The coil 23 is invalidated by the short circuit to reduce the abnormal effect by which the flash duration is increased, etc.

Title: Semiconductor memory
Inventor: SUZUKI MAKOTO
IPC: G11C11/34
Filed: 1988-06-08
Abstract: PURPOSE:To perform fast reading by obtaining voltage information by permitting the read current of a memory cell to flow from a data line to a common data line via a selection circuit, and permitting it to flow on a connected load circuit. CONSTITUTION:PMOSFETs M17-M20 are turned ON only in a reading state where decoder output the inverse of Y1 or the inverse of Yn is set at an 'L' and a write signal WE at the 'L', and information which appears on the data line D1 or the inverse of D1, or Dn or the inverse of Dn is transmitted to the common data line CD3 or the inverse of CD3. In such a way, the information in the memory cell is read out and transmitted at high speed with the read current itself. The loads M21-M24 of the data line are turned ON at the time of performing the non-selection of a pair of data lines (columns) and a write operation, which raises the potential of the data line. The source potential of the loads M21-M24 are decreased by VBE lower than the base bias VB of bipolar elements Q3 and Q4 in a common data line load circuit by diodes 15 and 16, and thereby, read delay due to remarkable change at the time of switching the pair of data lines to selection can be prevented from being generated. A voltage with a phase opposite to that of the gates of the PMOSFETs M17-M20 is impressed on the gates of the loads M21-M24. By employing such constitution, a RAM operated at high speed and with low power consumption can be obtained.
