Abstract: PURPOSE:To automatically detect a halftone screen area included in a document original at high speed and to remove halftone screen information while preserving character information by pickin-up a small dot constituting the halftone screen area from inputted decument image data and evading half-tone dot meshing information within the half-tone screen area from document image data. CONSTITUTION:The document image original is inputted from a scanner and stored in an image memory as document image data. A central atithmetic processor reads a halftone screen area processing program from a processing program storage ROM, executes the pick-up processing of the halftone screen area as against document image data in a work area RAM. Concretely, a threshold value corresponding to a character size used in the document to be processed is set so that only halftone screen dot information in the document image is picked-up as the small dot. At this time, a rectangular coordinate picked-up as the halftone screen area by RAM is also held. Then, character recognition is processed by pattern matching, etc.

Title: Information processor
Inventor: ITO YASUNOBU
IPC: G11B19/28
Filed: 1994-09-01
Abstract: PURPOSE: To enhance response of an information processor by reading out information quickly without sacrifice of durability of a mechanism for driving a memory medium. CONSTITUTION: When predetermined conditions are satisfied, a request for doubling the driving speed of a drive motor 56 rotating at a normal speed is delivered. Consequently, the drive motor 56 is driven at a double speed thus rotating a disc 52 at a double speed. Data is read out at high rate from the disc 52 rotating at a double speed and when a predetermined time elapses after the predetermined conditions are satisfied, the drive motor 56 is switched to a steady speed. When the predetermined conditions are not satisfied, data is read in under a state where the drive motor 56 is rotary driven at a steady speed to rotate the disc 52 at a normal speed. Since the drive motor 56 is driven with a double speed only when it is required, response of an information processor can be enhanced without sacrifice of durability of the drive motor 56.

Title: Resist process and multilayered resist film
Inventor: NAKANO HIROYUKI
IPC: G03F7/11
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To obtain a resistance film of exact pattern by interposing a barrier layer, which shuts off the chemical interaction of an antireflection film and the resist film, between these films, thereby preventing the cross interference of the resist and the antireflection film. SOLUTION: The resist film 21, the barrier film 22 and the antireflection film 23 are laminated, successively from a substrate 11 side, on a substrate 11. This barrier film 22 is formed in order to avoid the direct contact of the resist film 21 and the antireflection film 23 in order to prevent the crossreaction of these films. Since the barrier film 22 is formed on the resist, the barrier film preferably has the transparency to an exposing wavelength. If the film has a high acidity, the resist is adversely affected and, therefore, the film close to be neutral is preferable. Further, the pH of the liquid compsn. to be used at the time of application is preferably in a range of 5 to 9 as this film is the ground surface for application and when the influence on the resist film reacting with the acid is taken into consideration.

Title: Amplifier device
Inventor: MIKAMURA YASUKI
IPC: H03F1/32
Filed: 1989-09-11
Abstract: PURPOSE:To obtain an output signal with less distortion even when a large photocurrent comes by shifting a level with a shift circuit so that an output signal of an integration circuit opens a gate circuit when an input signal of a transimpedance type amplifier is larger than a prescribed value and forming a shunt. CONSTITUTION:When an input optical current iPD coming to a transimpedance type amplifier 2 is increased, its output voltage Vout is decreased accordingly. The output voltage Vout is shifted up to an input level of an inversion circuit 102 by a level shift/buffer circuit 101. Then a signal inverted by the inversion circuit 102 is increased resulting from the phase inversion as the input optical current iPD increases. Thus, the FETQ5 is conductive when the average value of the light power made incident in the photodiode 1 exceeds a prescribed value by selecting properly a threshold voltage of the FETQ5 to a value and a shunt branching part of the input optical current iPD is formed.
