Patent JP-H0473038-A (JP)
Title: Refractometer
Inventor: KOBAYAKAWA YOSHI
IPC: A61B3/10
Filed: 1990-07-13
Abstract: PURPOSE:To enable highly accurate measurement while keeping a person to be inspected from being bothered by projecting a luminous flux from a direction eccentric with respect to an optical axis of a lens for measuring an eye refraction value to receive the reflected luminous flux from the eyeground on a photoelectric sensor through the lens. CONSTITUTION:Luminous flux from a light source 1 travels on an optical path L1 and is projected to an eyeground Er passing the center of a pupil Ep of an eve E to be inspected through a lens 2, an opening of a stop 3, a bored mirror 4, a mirror 5 and an objective lens 6. The reflected luminous flux from the eyeground Er is reflected with the mirror 4 and then, separated from an optical axis 02 with a separation prism 9 through a stop 7 and a lens 8. Six luminous fluxes are projected to a image sensor 10 and a refraction value is calculated from positions of the fluxes. At this point, the eye E to be inspected stares at a target 12 with a direction of eyesight thereof aligning the optical axis 01, but it is kept from being bothered by the luminous flux from a light source 1 as an optical path L1 of the luminous flux from the light source 1 does not align the optical axis 01. Difference of an optical path L2 of the reflected luminous flux from the optical path L1 allows the preventing of the reflected luminous flux with the objective lens 6 from being received on the image sensor 10.

Abstract: PURPOSE:To make it possible to impress three kinds of pulses on one electrode by a circuit having a simple constitution by connecting a transistor for making a row electrode on which three kinds of voltage pulses are impressed to be zero potential and the transistor for impressing a maintenance voltage pulse width all the row electrodes through diodes. CONSTITUTION:In the case of impressing a maintenance pulse voltage on even- numbered row electrodes S2, S4,..., and Sm-1, only an N channel FET(TR2) is turned on, and the other FETs are turned off. In order to independently give a scanning pulse or an erasing pulse on respective even-numbered row electrodes S2, S4,..., and Sm-1, only the one out of the N channel FETs (TRA2, TRA4,..., and TRAm-1) is turned on, and all the other FETs are turned off. In the case of requiring to output the maintenance pulse voltage, a scanning pulse voltage, or an erasing pulse voltage, a P channel FET(TR1) is turned off. Thus, the three kinds of pulses are easily impressed by surely performing the operation.

Abstract: PROBLEM TO BE SOLVED: To form an excellent gate oxide film by thermal oxidation method, by inserting a substrate into an oxidizing furnace so that the surface temperature of a substrate where a silicon film is made may go up at a specified temperature rise speed or under. SOLUTION: An Si film 1-2 of a nonsingle crystalline semiconductor film is grown on insulating amorphous material 1-1. Then, a gate oxide film 1-4 is made by thermal oxidation method, but at this time, the temperature of an oxidizing furnace for insertion is set to an ultralow temperature of, for example, 600 deg.C. Then, the substrate insertion speed is set so that the temperature rise speed at the surface of the substrate until reach to the center of the oxidizing furnace of the substrate may be 20 deg.C/min. or under. After that, the temperature of oxidizing furnace is raised to a specified oxidation temperature at a temperature rise speed of 20 deg.C/min. or under.

Title: Receiving device
Inventor: SUGIYAMA TAKATOSHI
IPC: H04B1/26
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To receive a superimposed transmission signal and to prevent the omission of information or the interrupt of communication by detecting the presence or absence of a large power signal contained in the received signals and changing the amplification factor of a small power signal as a constant amplitude based on the detection result. SOLUTION: A receiving device 8 inputs the signals received via a nonlinear transmission line 3 to a large power signal extractor 7, a large power signal detector 4 and a small power signal extractor 5. The detector 4 detects the presence or absence of a large power signal contained in the received signals and outputs the detection information. Then a level controller 6 amplifies the amplitude of the output signal of the extractor 5 by a degree equivalent to the suppression level of the small power signal based on the detection information outputted from the gate signal generator of the detector 4 only when a large power signal exists. Thus, the controller 6 instantaneously decides a constant amplitude of the small power signal.  As a result, a constant amplitude is secured for the small power signal existing in a section where a large power signal is included and also for the small power signal existing in a section where no large power signal is included.

Abstract: PURPOSE:To form a good toner image, to improve transfer efficiency and to obtain copies having high image quality, by applying AC voltages having a phase between a photosensitive drum and peripheral devices, and acting periodic electrostatic forces upon a developer. CONSTITUTION:The output of the DC bias circuit 14 of an AC electric power source circuit 11 is connected to a photosensitive drum 1, a corona discharger 4, etc. and an AC voltage V1 is applied. The other end side of a transformer 17 is connected to a sleeve 9, etc. of a developing device, and an AC voltage V2 differing in phase by 180 deg. from the voltage V1 is applied. Therefore, mutual electrostatic forces are generated between the drum 1 and the sleeve 9, and the electrostatic forces act upon the developer in superposition with the electrostatic force of the latent images. According to the combined forces thereof, the developer 10 is oscillated by which good toner images are formed. Owing to the effect of the electrostatic forces generated like AC, transfer efficiency is considerably improved as compared to the prior art. Thus copying having high quality is obtained.
