Title: Method for removing photoresist material in original position
Inventor: TEI RYUICHI
IPC: G03F7/42
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to remove a photoresist material in an original position by etching a target by use of a pattern on the photoresist material on an etching machine, removing part of the photoresist by use of a plasma and removing the entire photoresist by use of a solvent. SOLUTION: The step of patterning and forming a complementary type metal oxidized film semiconductor (CMOS) photosensor 10 and the stage of removing a completely dried photoresist layer 24 are executed on the same etching so as to eliminate the need for transferring the CMOS photosensor 10 onto another etching machine. The production time for forming the CMOS photosensor 10 is thereby saved. Further, the external influences from the environment decrease. The oxygen plasma in the original position is given in order to remove the portion of the dried photoresist layer 24 during executing the pattern forming step. The solvent is thereafter used in order to effectively removing another photoresist layer 24 on the polyacrylate layer of the CMOS photosensor 10.

Filed: 1991-05-31
Abstract: PURPOSE:To watch a desired program without requiring waiting time by separating and extracting a text signal from a receiving signal by a text signal separation circuit and storing the extracted character signal in a non-volatile magnetooptical disk. CONSTITUTION:An antenna 1 is connected to a channel selection/demodulation circuit 2 and serves to demodulae the video signal of a selected channel. A synchronizing separation circuit 3 separates a horizontal synchronizing signal from a video signal and generates a reference clock for waveform equalization and text signal separation. On the other hand, a waveform equalization circuit 4 forms the waveform of the video signal while referring to the reference clock and outputs it to a text signal separation circuit 5. The text signal separation circuit 5 separates the text signal according to the reference clock and stores it in a buffer area 6-1 provided within a magnetooptical disk 6. The magnetooptical disk 6 is provided with the buffer rear 6-1 and a storage area 6-2. Thus, much television teletext broadcasting can be stored over a long period of time.

IPC: G06F3/12
Filed: 1985-06-14
Abstract: PURPOSE:To execute partial printing from an optional line of a displayed document by forming a partial printing mode in addition to a normal printing mode. CONSTITUTION:When a character code is inputted by an operator through a keyboard 12 in a document formation mode, a document formed under control by a CPU 10 is displayed on a display unit 13.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To automatically return an active latch to its normal position by closing a door even if the active latch takes an abnormal position by making a contact surface between a latch lever and the active latch slant. SOLUTION: A latch 1 for selectively taking an opening state, a half closed state or a full closed state for a door is maintained in its position by a pole 8.

Title: Method for measuring thickness of sio2 film
Inventor: USUKI TOMOAKI
IPC: G01N9/24
Filed: 1990-05-18
Abstract: PURPOSE:To make it possible to compute the thickness of a film by using the total strength of the spectrum of a specified wafer and the strength of the spectrum in the 0-value state, when the film of an SiO2 film which is formed on the surface of a Si substrate is obtained by a photoelectron spectroscopy method. CONSTITUTION:AlKalpha and MgKalpha are used as X-ray sources, and a Si wafer having a thin SiO2 film is measured. Then, the peak area strengths of the spectrums of Si2p and Si2s under the states including the 0-value state and oxidized state become constant regardless of the thickness of the oxide film when the thickness of a carbon-based film at the outermost surface is constant (including the case without any film at all). This fact indicates that the values of Isi-M and Isi-Mexp(-t'/lambda'sintheta) agrees with the peak area strengths of Si2p or Si2s under the states including the 0-value state and the oxidized state which are measured with a sample having the oxide film. The fact also means that the values are obtained without considering the measurement of the Si spectrum of a clean surface and the carbon film at the outermost surface. The thickness of the oxide film is readily obtained based on these numerical values and the strength of the metal component of the Si spectrum which is measured in an actual sample.

Filed: 1993-05-31
Abstract: PURPOSE:To realize high orientability and to obtain a high modulation degree by sealing a liquid crystal between IR transmission plates, providing the liquid crystal side surfaces of these IR transmission plates with parallel arranged grid-like gold electrodes and arranging the IR transmission plates in such a manner that these electrodes intersect orthogonally with each other. CONSTITUTION:The IR transmission plates 1 have the parallel arranged grid-like gold electrode 2 and function as polarizing plates and oriented films. Incident light is polarized by the parallel arranged grid-like gold electrode 2 and is double refracted and optically rotated within the liquid crystal layer. The liquid crystal molecules change their direction by 90 deg.. IF rays are optically rotated and passed therethrough. Then, a second polarizing plate is in relation to be arranged in intersecting orthogonally with a first polarizing plate. On the other hand, the liquid crystal is arranged by directing its major axis toward the progressing direction of the IF rays if a voltage is applied to the parallel arranged grid-like gold electrode 2 and, therefore, the IR rays are no longer optically rotated and the direction of the axis of polarization passes the inside of the liquid crystal. The second polarizing plate is arranged orthogonally with the first plate and, therefore, the IR rays can no longer pass this plate.

Abstract: PURPOSE:To realize a tracer control to a curved surface by a floating mechanism using software without using any sensor. CONSTITUTION:A tool coordinate system Ot-XYZ is set so that a Z axis can be directed toward a center Of of a face plate. A tool I is in contact with the surface GAMMAto be copied at all times and propagates power each other. A robot RB is taught to be moved at velocity (v) in the direction of a double arrow H. The force of each axis Jj is calculated from the product of position deviation and position gain, a vector with this power as components as many as the number of axes, this vector is transformed to the vector of a three-dimensional space, and a normal vector <N> on the surface GAMMA at that position is decided. The posture of the robot is controlled without changing the position gain so that the direction of the vector <N> can be matched with the direction of the Z axis. Next, respective axial position gains that the force in the direction of the vector <N> becomes a fixed value W, are obtained by fixing the position deviation, and matched with that value. Further, a tangential direction at that position is obtained, the target moving position of the robot RB is decided, each axial position deviation adding amount required for applying the velocity (v) is calculated, and it is added to the position deviation counting part of a position control loop.
