Abstract: PURPOSE:To remove a residual matter (remainder) of a resist pattern on a glass substrate in order to obtain a resist pattern of a specified shape, and to avoid problems of short when the pattern is used for a liquid crystal device. CONSTITUTION:A metal thin film is formed on a glass substrate G, on which a resist film is formed. After a resist pattern is formed by photolithography, the resist is irradiated with UV rays of 0.5-20J/cm<2> in a UV irradiation chamber 1. Thereby, even when the resist pattern is formed into other than the desired shape but including a residual matter, the residual matter is removed by UV rays. Then, the metal thin film is etched in an etching room 2 to form an electrode of a specified shape.

IPC: H04N1/46
Filed: 1991-04-23
Abstract: PURPOSE:To attain color picture processing while taking human sensation into account. CONSTITUTION:An RGB color picture signal is subject to signal conversion to obtain an L,Cab,Hab system color picture signal. In the case of a skin color region, the correction quantity is decided by fuzzy inference and the correction quantity is added to an original signal as the picture processing. The corrected signal is converted into a YMC signal suitable, e.g. for color print. A membership function in the case of implementing the fuzzy inference is decided by designating a desired area for each picture implementing correction picture processing based on the color information of the designated area.

Title: Optical amplification device
Inventor: KOGA TADASHI
IPC: H01S3/10
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive, reliable optical amplification device which can prevent optical surge with a simple optical circuit. SOLUTION: An input signal light 40 is inputted to an optical input off detector 43 where the light is branched into two light signals by a CPL(coupler) 45. One of two light signals branched by the CPL 45 is input to a light receiver 46 to be converted therein to an electric signal corresponding to the branched light power. The other light signal branched by the CPL 45 is input to an optical signal cut-off section 44 as it is. The electric signal converted by the light receiver 46 is compared by a controller 48 with a predetermined value. When the electric signal is smaller than the predetermined value, the controller 48 cuts off an optical path of a SW(switch) 47 to an optical direct amplifier 42.  When the electric signal is larger than the predetermined value, the controller 48 controls connection of the optical path in such a manner that a control signal to the SW 47 varies more slowly than a time constant for constant output control of the optical direct amplification circuit 42.

Title: Manufacture of semiconductor device
Inventor: OOSONE TAKASHI
IPC: H01L21/76
Filed: 1984-05-09
Abstract: PURPOSE:To form an element isolation region having minute dimensions in simple processes, by selectively etching a first coating film and a substrate to form a recess which is filled with a second coating film, and by selectively removing the second coating film by etching to lift off the first coating film. CONSTITUTION:A recess 12 is formed by etching selectively a two-layer film 10 consisting of SiO2 and Si3N4 films, an Mo film 11 and an Si substrate 1. Conditions of RF bias spattering are properly applied for filling the recess with an SiO2 film 13 so as to have a flat surface. The SiO2 films 13 and 13' are then selectively and anisotropically etched until the side faces of the Mo film 11 are exposed. The Mo film 11 thus exposed is selectively etched by mixture liquid of (H2SO4+H2O2) so that the SiO2 film 13' is lifted off and an element isolation structure having a flat surface can be obtained. Further, an active region 1' is not damaged during the anisotropic etching of the Mo film 11 thereabove and therefore the deterioration in element characteristics can be avoided.

Title: Inverter system and its controlling
Inventor: HASEGAWA MASAYASU
IPC: H02M7/48
Filed: 1994-04-28
Abstract: PURPOSE:To prevent the stoppage of the operation of an inverter system by stopping the increase in the frequency of the A.C voltage until the D.C voltage becomes a second set voltage level which is higher than a first one when the D.C voltage drops to the first set voltage value at the acceleration of an A.C motor. CONSTITUTION:At the acceleration of an A.C motor, the current D.C voltage value is read first (S1a). Then, it is judged whether a present 'undervoltage under control' flag is on or off (S1b). When the D.C voltage level is the same as the 'undervoltage under control' level or below, the 'undervoltge under control' flat is turned on (S1f) and the previous output frequency is used as the this-time output frequency (S1i) and the increase in the output frequency of the A.C voltage is stopped until the D.C voltage increases by the hysteresis to a second set level. By this method, the stoppage of the operation of an inverter system is prevented by protection operation due to undervoltage even in the case that the line voltage is low or the capacitor of the power supply is small.

IPC: G11B15/24
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To easily extend the consecutive time of a video recording pose by the user. SOLUTION: In this video tape recorder, the video recording pose is released (ST32, 35, 36) when the consecutive time of the pose becomes 2 min and 50 sec near 3 min which is the maximum consecutive time at the time of video recording pose, and the video recording pose is reopened (ST38, 40, 30) after a lapse of 10 sec, then this process is repeated till the pose release operation is made (ST33, 39) by the user's depressing of a pose key 19a. Consequently, such an operation by the user as the video recording pose is released a little before the maximum consecutive time of the video recording pose and made again to the video recording pose after that, like the conventional practice, is unrequired, then the consecutive time of the video recording pose is easily extended by the necessary amount.
