Title: Matrix display panel of uniform display
Inventor: FUJITA SHINGO
IPC: G02F1/1343
Filed: 1984-05-10
Abstract: PURPOSE:To realize the uniform display brightness by distributing the resistance in electrode lead-out parts as a function of the distance in the direction where electrode groups facing each other are arrayed thereby compensating the potential attenuation of the electrodes on the opposite sides and maintaining impressed voltage at a substantially specified voltage. CONSTITUTION:The figure shows the case in which the length of X electrodes is long and the potential attenuation by the electrode resistance at the X electrodes is considerable. The voltage to be impressed to a display medium is the difference between the X side potential and the Y side potential in a place to be looked and the voltage to be impressed to the display medium is maintained substantially constant by increasing the potential on the Y side in the potential decreased part on the X side. The quantity of the potential decrease on the X side changes with the distance from the transmision end on the X side and therefore the potential on the Y side must be correspondingly changed. The resistance in the lead-out electrode parts on the Y side is thus adjusted by changing the width and length thereof.

Abstract: PURPOSE:To enable the precise detection of the content ratio of alcohol, by providing a light-emitting element and a one-dimensional light position detecting element at one end of a light-transmitting body and by providing a plane of refraction with fuel and a plane of reflection at the other end thereof. CONSTITUTION:A light-emitting element 4 provided at one end of a light-transmitting body 1 is driven 101 to emit a light, and an emission light 14 thereof is made to be incident at an incident angle psi at a point P0 on a plane 15 of refraction at the other end of the light-transmitting body 1 through a stop 12 and a lens 13. Since this plane 15 of refraction is in contact with fuel flowing in from a fuel inlet 17, the incident light 14 is refracted at an angle chi of refraction at the point P0 due to a difference in a refractive index between the fuel and the light-transmitting body 1. Next, the refracted light is transmitted through the fuel, reflected at a point P1 on a plane 11 of reflection, refracted again into the light-transmitting body 1 at a point P2 on the plane 15 of refraction in accordance with the relation formula between the incident angle psi and the angle chi of refraction, and made to be incident on a semiconductor position detecting element 16. Then, photocurrents i1 and i2 from electrodes I1 and I2 of the element 16 are inputted to a detecting circuit 10, amplified 102 and added up 103 thereafter, and the current i2 is divided 104 by an addition value and outputted as a voltage Vout corresponding to a position signal.

Filed: 1990-04-11
Abstract: PURPOSE:To effectively carry out an advance reading job by obtaining the increment of address signals based on a data size signal and generating an advance read address signal for the next data access. CONSTITUTION:An address signal is received from a host device 1 for access of data together with a data size signal showing the size of the single unit of the access data. An address arithmetic part 20 obtains the increment of the address signals based on the output of a data size latch part 22 and generates an advance read address signal for the next data access. Thus the advance reading action is switched in response to the memory reading action of the device 1. Then the coincidence rate of addresses is improved and a mem ory is read at a high speed.

Filed: 1994-05-06
Abstract: PURPOSE:To suppress the degradation of reception characteristics caused by the leakage of transmission carriers at the time of reception with low-priced and simplified configuration at the miniaturized radio equipment. CONSTITUTION:An oscillator 1 oscillates an oscillating signal provided with a (2/3)-fold oscillation frequency as high as the local frequency of a local signal to be inputted to a quadrature modulator 6. A 1/2 frequency divider 3 divides the oscillation frequency of the oscillated signal to one half and outputs a 1/2 frequency-divided signal. A three-multiplier 4 multiplies the frequency of the 1/2 frequency-divided signal by three and outputs a signal multiplied by three. The signal multiplied by three is outputted to the orthogonal modulator 6 as the local signal. At the time of reception, the frequency dividing operation of the 1/2 frequency divider 3 is stopped but at the time of transmission, the frequency dividing operation of the 1/2 frequency divider 3 is performed and the required local signal is provided. On the other hand, a 1/ 5 frequency divider 5 divides the oscillation frequency of the oscillated signal outputted from the oscillator 1 into 5 stages and supplies the signal frequency-divided into five stages to a second mixer 25 of a receiving part as the second local signal.

Filed: 1990-04-11
Abstract: PURPOSE: To measure the thickness of a film thinner than 1μm by bridging the pole pieces of an electromagnetic sensor embedded in a shaft through a lubricant film having high permeability and detecting variation of the impedance of a coil. CONSTITUTION: An electromagnetic sensor 4 comprising an annular iron core 5 and a coil 6 is embedded in a shaft 1 and the externally extended part of the core 5 forms pole pieces 7, 8. The gap between the pole pieces 7, 8 is filled with magnetic powder, for example, and the pole pieces 7, 8 are bridged through a lubricant film 3 having high permeability. When an AC current is fed to the coil 6, a field is generated as shown by dot lines 10 and the impedance of the coil 6 depends on the thickness of the lubricant film 3 at that time. According to the method, thickness of the lubricant film 3 can be measured with high accuracy in the range of 0.1-20μm.

Abstract: PURPOSE:To raise the suction efficiency and to make the title device small in size and light in weight by setting the flow rates of sheath air and purge air to <=1/2 of a flow rate of sample air, respectively and allowing a suction side duct to suck all of the sample air. CONSTITUTION:When a vacuum pump 21 is driven, sample air containing fine grains in a measuring area is blown out of an internal nozzle 4 through a duct 6, and sucked by a suction nozzle 17.
