Title: Measuring method of minute displacement and apparatus therefor
Inventor: YOSHITAKE YASUHIRO
IPC: G01B11/00
Filed: 1990-11-09
Abstract: PURPOSE:To measure a minute displacement with reduced influences of the distribution of the air density by a method wherein the light is incident with about 1/2 the primary angle of diffraction to a diffraction grating, the generated diffraction light, regularly reflected light and a light of a different wavelength are subjected to heterodyning interference thereby to generate a measuring signal and a reference signal, and the phase difference of the signals is obtained. CONSTITUTION:A light projected from a linear polarizing laser 11 is divided into three. Two of the luminous fluxes are brought into a diffraction grating 7 as a light LB1 with approximately 1/2 the primary angle of diffraction, so that the primary diffraction light and regularly reflecting light are generated. The other luminous flux is divided into two as a light LB2 while the wavelength is made slightly different. When the primary diffraction light and regularly reflected light of the light LB1 and the light LB2 are subjected to heterodyning interference, a measuring signal and a reference signal are optically detected at 91, 92. The phase difference of the signals is obtained. In this manner, the optical path of the light LB1 for forming the measuring signal is made close to the optical path of the light LB1 for obtaining the reference signal, and also the optical path of the light LB2 for the two signals is rendered close. Accordingly, it becomes possible to measure the displacement hardly influenced by the distribution of the air density.

Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain an element having stabilized performance even if the size of individual element is reduced to limit the width of the active region by making thick the pad oxide in an NMOS forming region and making thin the pad oxide in a PMOS forming region. SOLUTION: After removing an initial oxide 32 and a first oxide 36, a first oxide 38 and a second photosensitive film 39 are deposited sequentially on the entire surface. After the second photosensitive film 39 is exposed and developed selectively to remove the upper side of an n-type well 35, the first oxide 38 is etched selectively using the second photosensitive film 39 as a mask and then the second photosensitive film 39 is removed. Subsequently, a second pad oxide 40 is grown on the entire surface of a semiconductor substrate 31 including the selectively etched first oxide 38. Since the first and second pad oxides are laminated on a p-type well 37, it become thicker than the pad oxide on the n-type well 35.

Title: Ink jet recording method
Inventor: ROBAATO ENU JIYOONZU
IPC: C09D11/00
Filed: 1996-11-14
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording method comprising jetting ink drops from an orifice according to the recording signals to thereby form an image on a recording medium, wherein a plurality of specified substances and colorants are added to the ink used to make it possible for the ink to give an image having quality equivalent to that obtained by a xerographic image formation method.  
     SOLUTION: A liquid vehicle, toner particles and a colorant are added to the ink used. Namely, an ink composition is produced by a combination of a formulation and production method for a xerographic toner with formulation and production method for an ink jet recording ink. For example, a latex emulsion of a styrene/butyl acrylate/acrylic acid copolymer is produced by emulsion polymerization. This emulsion is mixed with a colorant, and toner particles are agglomerated and united in this emulsion to form a dispersion of toner particles. The diameter of the toner particles is reduced to form an ink composition.

Filed: 1988-11-30
Abstract: PURPOSE:To enable a mode to be established automatically according to a service form of reading or printing by a method wherein a mode establishing operation means establishing a functional mode on a reading surface or a printing surface when the functional mode thereon is pushed down, is free to access a body and protrudes outward. CONSTITUTION:A first and a second buttons 6, 7 are positioned in depressed positions 21, 22 formed on faces 2, 3 of a body 1, and a top part 23 of the body slightly protrudes from the surfaces 2, 3. When an image is read, a hollow drum 4 is conformed to an image on a copy 31 to be read via a contact plate 5. Since the first button takes refuge in the depressed position 21 of the body 1 with the copy 31 at that time, a switch turns on and a reading mode is automatically established. Then, when the body 1 is turned over to be placed on transfer paper in the case of printing operation, the second button 7 turns a microswitch 29 on this time to establish a printing mode automatically.

IPC: G01N21/956
Filed: 1987-12-02
Abstract: PURPOSE:To enable the accurate diagnosis of abnormality without suffering the effects of expansion, contraction, positional slippage and a quantum error of a substrate, by conducting self-diagnosis of a pattern inspecting means on the basis of a stable image signal for self-diagnosis. CONSTITUTION:At the time of ordinary pattern inspection, a switch 5 incorporated in a pattern inspecting apparatus 3 is changed over onto the contacts (a) and (a') sides, and image signals obtained by picking up substrate patterns 1 and 1' by TV cameras 2 and 2' are connected to the apparatus 3, so as to conduct the inspection of the patterns. At the time of self-diagnosis, the switch is changed over onto the contacts (b) and (b') sides, and a pattern generator 6 outputs an image which is free from expansion, contraction, positional slippage, etc. This image is binary-coded correctly, since it is a digitized image pattern signal obtained by reading and outputting in a prescribed cycle an image pattern stored in a pattern memory. Accordingly, it is possible to conduct self-diagnosis before the inspection of the substrate patterns and thereby to diagnose an abnormality operation for feature extraction and the like.

Title: Pressure sensor
Inventor: OKANO HIDEO
IPC: G01L9/00
Filed: 1988-12-02
Abstract: PURPOSE:To increase the output change rate to a pressure change by inserting a pair of FETs between the bridge circuit and constant current circuit of a pressure-sensitive element and applying the output voltage of the bridge circuit to the gates of the respective FETs in a crossing state. CONSTITUTION:When the resistance values of resistors R1, R3 are reduced and those of resistors R2, R4 are increased by the change of the pressure applied to a bridge circuit, the voltage E1 of an output terminal 15 is increased and the voltage E2 of an output terminal 16 is reduced. The passing current 12 of an FET 12 is increased by the increase of the voltage E1 of the terminal 15 and the passing current 11 of an FET 11 is reduced by the reduction of the voltage E2 of the terminal 16. As a result, the voltage E1 is increased by the reduction of the current I1 and the voltage E2 is reduced by the increase of the current I2 and both voltages become equilibrium in this state. Therefore, the output voltage of a sensor is increased synergistically and can be taken out as sufficiently large output even when amplifying circuit is not provided.
