Title: Method and device for discriminating automatically picture classification and method and device for determining threshold for discrimination
Inventor: UZUKI KAZUYOSHI
IPC: H04N1/46
Filed: 1993-06-10
Abstract: PURPOSE:To automatically discriminate a picture read by a scanner, etc., by obtaining the average value of the chroma saturation of a prescribed number of the higher order picture elements whose chroma saturation is high among all the picture elements, and making it the upper limit value of the chroma saturation, and discriminating the picture to be a color picture when the upper limit value is over a prescribed monochromatic/color threshold, and discriminating the picture on the basis of the fractal dimension of lightness and the chroma saturation for more detailed discrimination. CONSTITUTION:The picture whose classification is unknown is read (step 4), and picture classification is discriminated automatically by using the threshold incorporated in a program (step 5). Namely, first of all, RGB of the picture is converted into hue H, the chroma saturation S, and the lightness I. Next, when the upper limit of chroma saturation S is smaller than the monochromatic/color threshold, the picture is judged to be a monochromatic picture, and the classification of a monochromatic photograph, word-processor documents, and a dot photograph can be discriminated by obtaining the fractal dimension, etc., about the lightness I. Besides, when the upper limit is larger than the monochromatic/color threshold, the picture is judged to be the color picture, and the fractal dimension, etc., about the chroma saturation is obtained. Thus, the classification of a primary color picture and a natural color picture (color photograph) can be discriminated.

Title: Computer system
Inventor: ASHIZAWA YUJI
IPC: G06F12/00
Filed: 1985-07-26
Abstract: PURPOSE:To easily rewrite an execution program at need by providing a readable/rewritable memory part in a subsystem and also providing a disconnection part which disconnects a central processing part from an internal bus line. CONSTITUTION:When the program is modified, a bus switching control part 11 controls a central processing switching part 8 on the basis of a command signal from the 1st central processing part 1 to disconnect the 2nd central processing part 4 from the internal bus line 6 and also controls a bus switching part 10 to switch the connection of the readable/writable memory part 9 from the line 6 to an external bus line 3. In this state, a new execution program is written in the memory part 9 from the processing part 1 through a line 3. The control part 11 connects the processing part 4 to the line 6 after the writing and the memory part 9 is switched to the line 6 to execute the program written on the memory part 9.

Title: Spin coater
Inventor: MORIZAKI TAKESHI
IPC: G03F7/16
Filed: 1990-06-20
Abstract: PURPOSE:To prevent the mist of a coated solution from adhering to the rear surface of a disc such as a wafer, etc., being spin-coated by a method wherein a means pouring air stream in the outer peripheral direction from the center of the disc is provided on the rear surface of said disc. CONSTITUTION:A holder 1 having the fan role pours an air stream in the outer peripheral direction of a disc 2 by the torque of the holder 1. Next, slots 14 are formed in the radial direction on the rear surface of the holder 1 so that the part between adjacent slots 14 may fill the role of blades. When the slotted holder 1 is spinned to drive the disc 2, the holder 1 itself works as a fan so as to pour the air stream running into the outer peripheral direction of the disc 2. Furthermore, the holder 1 itself may be implanted with blades instead of making it rugged for filling the role of a fan.

Title: Counter circuit
Inventor: OKINO TAKAYUKI
IPC: H03K23/58
Filed: 1982-09-22
Abstract: PURPOSE:To prevent a large counting error due to a pulse having a pulse width below a prescribed value, by inserting a monostable multivibrator to an input circuit of a clock pulse. CONSTITUTION:The monostable multivibrator 11 is inserted between a clock pulse input terminal and a counting element of a counter circuit which drive plural counting elements C1, C2, Cn in parallel with the clock pulse CLK. The monostable multivibrator 11 does not produce an output when the pulse width of the pulse CLK is a prescribed value or below, but produces a pulse having a prescribed pulse width sufficient to drive the counting elements when the pulse width of the CLK is over a prescribed value. Since the pulse having the pulse width below a prescribed value is not inputted to the plural counting elements, no large counting error due to the variance between the counting elements occurs.

Filed: 1997-06-07
Abstract: PROBLEM TO BE SOLVED: To obtain a printer in which defective printing is prevented from being carried out under a state where a correct decision can not be made for defective printing. SOLUTION: When a facsimile data is stored in a receiving memory, a decision is made (S1-S3) whether the detected voltage Voff of a light receiving element is equal to or higher than 1.5V under a state where an LED is turned off. If Voff<1.5V a decision can be made that paper jam or ink empty can not be determined because of intensive external light and a message 'under receiving...' is presented on a liquid crystal display (S5) without starting the print operation. Consequently, a user can be notified that an unprinted receiving data is present. Forced printing is started (S7-S9) when the user operates a start switch. The receiving data is eventually deleted (S11-S13) in response to a reset command.
