Title: Display device and method for driving same
Inventor: ANDO TETSUO
IPC: G09G3/20
Filed: 1995-03-30
Abstract: PURPOSE: To eliminate the need for a correction circuit, reduce the response speed of an element, and prevent the number of processes for manufacturing the element from increasing by controlling in proportion to a signal to be displayed a current flowing through a cathode, when a field emission current between anode and cathode is proportional to luminance. CONSTITUTION: A voltage Va F from a constant-voltage power supply 65 and a voltage Vg F from a constant voltage source 64 are applied respectively to the anode 11 and the gate electrode 13 of a display device. A relation of Va F> Vg F is satisfied. Also, a current source 63 can be voltage-controlled, so that a current value Ia is controlled in proportion to a voltage VK applied via a terminal 17. Even if the characteristic of an element (cold cathode) 16 is varied or if the characteristic of the element 16 is varied due to changes with time, etc., the voltage Vk applied to the current source 63 is set so that a current value at which the required luminance L is obtainable is set, and thus the luminance does not vary.

Title: Metallic porous body with directional open pore, and its production
Inventor: NISHI TAKASHI
IPC: B22F3/11
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a metallic porous body having uniformly dispersed directional open pores, useful for component members of metallic molds (for resin injection molding, nonferrous metal casting, or the like), fluid spray conveyance members, adsorption members, or the like. SOLUTION: The porous body is a sintered body which has a bundle-like aggregate structure formed by subjecting mutually metallic wire sticks 1 to diffusion joining and in which voids P1 among the wire sticks penetrating in the wire-axis direction are uniformly dispersed. In the case where the metallic wire sticks are hollow, the porous body can be provided with the porosity where through holes P2 resultant from the hollow holes of the wire sticks are dispersed together with the voids P1 among the wire sticks. The porous body can be produced by arranging the metallic wire sticks parallelly to each other, filling them into a capsule, and performing controlled pressurizing/heating treatment to apply diffusion joining to mutual respective outside peripheral surfaces of the metallic wire sticks. By this method, high open porosity can be provided, and further, pore diameter and porosity can be arbitrarily controlled according to the wire diameter of the wire sticks to be used, the conditions of sintering treatment, or the like.

Title: Detecting device for asleeping drive
Inventor: SEKO TAKATOSHI
IPC: B60K28/00
Filed: 1979-06-12
Abstract: PURPOSE: To facilitate the detecting of an asleeping driving operation in a vehicle having a power steering mechanism by a method wherein the asleeping driving operation is judged with a steering operation signal produced by detecting a variation in hydrualic pressure in the powder steering mechanism.  
     CONSTITUTION: When no force is applied to a steering wheel 7, hydraulic oil is returned back to an oil reservoir 1 via a pump 2, a hydraulic sensor 6, a valve 21a, a valve 21b and annular grooves 23a and 23b, and thus the sensor 6 does not detect the hydraulic pressure. In turn, when the steering wheel is turned leftwardly, for example, the hydralic oil is flowed to the pump 2, the valve 21a, an oil passage 13, a pressure chamber 3a to depress a worm gear 3c leftwardly. At this time, the sensor 6 detects a hydraulic signal variation. In response to the hydraulic signal from the sensor 6, a signal 24a is produced at comparators 25 and 26 by a steering sensor 24. When the time ranging from a starting time in which the signal 24a is exceeded over the setting value V 1  to a setting value V 2  is shorter than the predetermined value of time, the asleeping driving is detected by a circuit of judgment 31 to generate an alarm.

Title: Analoggtoodigital converter system
Inventor: UIRIAMU DEE HARISON
IPC: H03M1/00
Filed: 1980-06-05
Abstract: An analog-to-digital conversion system uses a fast analog-to-digital converter having a resolution less than the system resolution to convert the difference between a previously predicted value and the current analog value. The converted difference is summed with the predicted value to compute the actual value of the analog input signal to a resolution greater than that of the fast analog-to-digital converter. The high resolution digital value thus obtained becomes the predicted value for the next conversion. This predicted value is converted by a digital-to-analog converter having the same accuracy but not the same resolution as the system output to an analog signal which is compared with the input analog signal to obtain a difference signal. This difference signal is sampled and held to provide the input to the fast analog-to-digital converter. The system includes a gain scaling and switching circuit to compensate for errors which would occur when the difference between the true analog input and the prediction exceeds the range of the low resolution, fast analog-to-digital converter.
