Title: Printing output control system
Inventor: OKA KOJI
IPC: G06F3/12
Filed: 1989-03-09
Abstract: PURPOSE:To print out data in the best state efficiently by adjusting the order of a large amount of output data and a small amount of output data automatically and giving priority to the small amount of output data when both the data are printed out on the same printing output device. CONSTITUTION:When there is a request from a job, an adjustment program 5 compares the amount 'bi' of output data in control data in a corresponding output data group with set data B. When bi is larger than B, namely, when the amount of the output data is larger than a limited value, it is considered that the amount of the output data is large, the priority level data 'ai' that the control data includes is changed into the the lowest priority level X, and the data which are already requested and queued in order are rearranged. Thus, when the data amount of the unit data group is larger than the limited value, the priority level is lowered and then a small-amount data group is outputted automatically and preferentially, so that the data are printed out in the best state with efficiency.

Title: Gain control circuit
Inventor: ISHIZAWA HIROAKI
IPC: H03G3/10
Filed: 1984-03-27
Abstract: PURPOSE:To obtain a gain control circuit which can stabilize the gain in a short time from a switching time point of a switch, by providing switches for reduction of resistance value at both ends of a resistance connected in series to a gain changeover switch. CONSTITUTION:A switch SW2 for reduction of resistance value is connected in parallel to a resistance R3 connected in series to a gain changeover switch SW1. When either one of both switches is kept on, the other is always turned off by control. In such a constitution, the time during which the coupling capacity C is charged from an instant the SW1 is turned off is reduced extremely compared with a case where no SW2 exists. While the charging time of the coupling capacity C' is shortened also when the SW1 is turned on. Thus the response time can be accelerated when the gain of an operational amplifier is switched. This can increase simply the signal processing speed.

Title: Production of printed matter
Inventor: SHIMONISHI HIDETO
IPC: G03F1/88
Filed: 1981-04-15
Abstract: PURPOSE:To show a character which is free from the superposition of halftone spots, by converting three among four sheets of negative films that have received the color separation into positive films by coating a masking agent to  sufficiently cover the characters and patterns at the positions where the films  are opposed to each other. CONSTITUTION:In case a character 2 is shown in white on the black background, a masking agent 3 is coated over the three of four sheets of negative films that have received the color separation excepting a film used for an ink  plate so that the character 2 is covered sufficiently at the positions where the  three negative films are opposite to each other. These four negative films are  reversed to obtain positive films. Using these positive films, the normal plate making and printing are carried out to produce a printed matter. The fringe  area of the characters on the printed matter is formed by just a single color of  ink plate and has no superposition of halftone spots. As a result, a high-contrast  white character is obtained on the black background.

Title: Image processor and thresholding method for image
Inventor: IWABUCHI TAKAHIRO
IPC: H04N1/403
Filed: 1996-03-14
Abstract: PROBLEM TO BE SOLVED: To threshold process an image without causing a regular pattern or a periodic pattern such as a textile. SOLUTION: An error calculation section 18 calculates a binary error in thresholding by a thresholding section 16 and the calculation result is stored in a buffer 20. An error average calculation section 22 receives a thresholding error of a picture element in existence around an object pixel and whose thresholding has already been conducted to calculate a mean error and the result of calculation is added to multi-level data by an adder 12. A pattern decision section 24 receives only a sign of the mean error stored in the buffer 20 as a predetermined discrimination object pixel in existence around the object pixel to decide how the decision object pixel is threshold processed and revises a threshold level set to the thresholding section 16 so as to suppress production of a textile when the decision section 24 decides there is a possibility of occurrence of the textile.

Title: Stable rolling method for irregular section steel sheet
Inventor: KAKEHI NOBUO
IPC: B21B1/26
Filed: 1986-03-15
Abstract: PURPOSE:To prevent sheet biasing and to produce a product having a good shape by providing excess metal parts to both sides of a material to be rolled from which one or plural lengths of irregular section steel sheets are simultaneously rolled and providing pressing parts consisting of slopes to rolling rolls. CONSTITUTION:The irregular section steel sheet in generation is rolled of plural lengths and in the case of, for example, two lengths, the excess metal parts 8, 8' and the pressing parts 9, 9' by roll calibers are provided to the material 4 to be rolled. Since the roll surfaces are inclined, the material 4 to be rolled receives reactions F, F' in the central direction respectively at the surface edges in the stage when the excess metal parts are pressed to the pressing parts 9, 9' and are rolled. The excess metal part 8' fills tthe pressing part 9' but the excess metal part 8 does not fill the pressing part 9 if the material 4 biases to, for example, a right direction. The rolling width of the pressing parts increases from the right side and decreases from the left side. The balance between the rolling reactions f, f' of the pressing parts and the reactions F, F' is, therefore, broken, and the right side becomes larger. The self-aligning effect by which the escape of the material 4 toward the outside direction by the edge part is prevented is thus induced.

Title: Time-base compressing and expanding device
Inventor: NOCHIDA KAORU
IPC: G11C19/28
Filed: 1987-03-12
Abstract: PURPOSE:To reduce noises originating from signal charge transfer operation by driving a CCD with two two-phase transfer clock pulse signals and reading a signal out of the CCD, equalizing 1st and 3rd pulse train signals in pulse width substantially to each other, and setting the pulse width to smaller than a half as large as a smaller period between 1st and 2nd periods. CONSTITUTION:When there is transition from a write period to a read period, variation in residual charge amount at the crooked part of the charge transfer channel of the CCD 22 is obtained as variation from a residual charge amount q4 to a residual charge amount q5 by variation from pulse width tau4 to pulse width tau5 as to a clock pulse of the other phase of the two-phase transfer clock pulse signal. Then the pulse width tau3 is made smaller than a half as large as pulse width tau2 to make the pulse width tau4 larger than pulse width tau1. Consequently, the residual charge amount q4 and residual charge amount q5 are made relatively small. Therefore, noise components contained corresponding to variation in residual charge amount at the crooked part of the charge transfer channel of the CCD 22 are reduced effectively.
