IPC: H04N9/64
Filed: 1986-11-10
Abstract: PURPOSE:To prevent degrading of S/N because of mixing noise from a chrominance signal system into the illuminance signal of a composite color television signal by adding a base noise clipping circuit to eliminate low-level chrominance signals to the circuit of the chrominance signal system. CONSTITUTION:In the base noise clipping circuit 7, a carrier chrominance signal is amplitude-amplified by an amplifier 9a, and by a limiter circuit 9 in the following stage, only such signal components, for instance, as equal to or lower than a slicing level Th are extracted. In thus extracted low level signals, noise components are included together with chrominance signal components. These low-level components are phase-inverted by an inverter circuit 9c in the following stage, then attenuated to a suitable level by an attenuator R2, and supplied to an adding circuit 9d. In such a manner, the low-level components are eliminated from the carrier chrominance signal supplied to the adding circuit 9d and a new carrier chrominance signal is thus formed. Accordingly, this signal is synthesized with the illuminance signal components by an adding circuit 10. As a result, the S/N of an illuminance signal can be upgraded.

Title: Fusion splicing method of single mode optical fibers
Inventor: WATANABE KO
IPC: G02B6/38
Filed: 1984-12-17
Abstract: PURPOSE:To prevent the increase in loss by pulling back optical fibers after a pushing stage then ending heating so that the once microbent cores are pulled to extend straightforward even if the eccentricity of the cores is large. CONSTITUTION:The cores are centered while the end faces of the optical fibers 10 are slightly apart from each other, then arc discharge is started and the fibers 10 are slightly advanced to bring the end faces into contact with each other and further the fibers are pushed toward each other. The heating is continued for the time t1 after pushing to the prescribed extent. The once pushed fibers are then pulled back. The extent of the pull back is made slightly larger than the extent of the push. Then the microbent cores 12 are pulled to extend and are thereby straightened. The extent of the pull back is made about half the extent of the push if the eccentricity of the cores 12 is small. The extent of the pull can be increased to about 3 times the extent of the push when the eccentricity is extremely large. The heating is continued for the time t2 after the pull back by the prescribed extent and thereafter the discharge is ended. The increase in loss is prevented in the above-mentioned manner.

Title: Page printer
Inventor: MATSUZAWA KUNIHIKO
IPC: B41J2/51
Filed: 1990-10-03
Abstract: PURPOSE:To prevent the generation of a drawing error by controlling a page printer so that printing is performed at the printing speed printable on one page of paper calculated from the quantity of image data when it is discriminated that the image data from a host apparatus can not be printed on one page of paper at set predetermined printing speed. CONSTITUTION:When the image data sent from a host apparatus is stored in a data buffer 2, a drawing quantity limit judging part 8 calculates the quantity of the data stored in the data buffer 2 on the basis of the data from a drawing part 3 to judge whether the data can be normally printed on one page of paper. When the data is judged to be incapable of being normally printed, this state is informed to a printing speed calculating part 9 and printing speed is calculated by the printing speed calculating part 9 so as to be capable of normally printing the data on one page of the paper. The printing speed is transmitted to a printing speed control part 11 through a printing speed transmission part 10 and the printing speed control part 11 controls the printing speed in a printing part 7 so as to set the same to the calculated printing speed. Even when drawing speed is changed by the quantity of the image data, it is prevented that the drawing speed becomes slower than the printing speed and the generation of a drawing error can be prevented.

IPC: B60W10/10
Filed: 1987-10-20
Abstract: PURPOSE:To prevent both drop and blowing up of engine speed by increasing an increment value of an intake air quantity as the engine speed increases at the time of switching from the no-running range to a running range of an automatic transmission. CONSTITUTION:An engine control unit 15 comprises an increment means 23 for increasing an intake air quantity supplied to an engine 1 when an automatic transmission 20 switches its function to a running range and an increment value setting means 24 for increasing an increment value of the intake air quantity caused by the increment means 23 as the engine speed increases. When the automatic transmission 20 switches its action from the no-running range to the running range. An increment of the intake air quantity caused by these means 23, 24 is to be realized by controlling a bypass air quantity owing to the control of a control valve 9. Thus, the intake air quantity can be properly regulated in response to the engine speed, at the time of switching to a running range, which may change depending upon the extent of stepping on a pedal just before the above switching.

Filed: 1999-09-20
Abstract: PROBLEM TO BE SOLVED: To improve visibility in the case of confirming a visitor who has made a calling operation, while the resident went out and is absent from the house. SOLUTION: A display device 24 displays the image of a visitor photographed by a camera 11 of an entrance slave set 1, when a control section 20 is set to an at-home mode through the operation of an operation section 22 of an indoor master set 2. When the control section 20 is set to a visit mode, the image is stored in an image memory 26 as a still image via an image recognition section 25. A binary processing section of the image recognition section 2 outputs white pixels to a centroid measurement section, when each frame of the image of the visitor is within all RGB ranges by referring to a threshold preset to prescribed ranges of R (Rlow-Rhigh), G (Glow-Ghigh), and B (Blow- Bhigh).  The centroid measurement section calculates a centroid of the received white level areas, calculates an evaluation value, whose value is highest in the image where an upper half of the visitor's body is in existence in the middle of the screen for each frame and stores only one image into the image memory, every time the maximum value is updated.
