Title: Method for segmenting special graphic
Inventor: SEKIGUCHI NAGISA
IPC: G06T7/00
Filed: 1992-02-27
Abstract: PURPOSE:To reduce the burden on an operator by efficiently segmenting a special graphic with less operation at the time of using a drawing automatic input device to segment the special graphic. CONSTITUTION:First, the operator designates a minimum area including the graphic to be segmented on a picture. The system of the drawing automatic input device takes out only vector elements completely included in the designated area. Next, the operator designates unnecessary vector elements shown by thick lines out of taken-out vector elements. The system deletes designated unnecessary vector elements and segments a set of remaining vector elements as graphic primitives.

Title: Automatic program searching device
Inventor: NISHIKAWA KENJI
IPC: G11B15/087
Filed: 1982-03-13
Abstract: PURPOSE:To perform program searching operation easily, by running a tape at a high speed when a tape scan switch is pressed and then performing reproduction for a specific time once an intermusic gap is detected and running the tape at the high speed again, and repeating said operation until the tape scan switch is pressed again. CONSTITUTION:When the tape scan switch 201 is pressed once, an in-tape-scan memory circuit 202 outputs an in-tape-scan signal and a generating circuit 203 for a program search signal for one piece of music controls a program searching circuit 200. The tape is run at the high speed and once an intermusic gap is detected, reproduction is started and a timer 204 is set. A time-out signal 204 is generated the specific time later and the circuit 203 is driven again. When the tape scan switch 201 is pressed during the reproduction of a desired piece of music, the in-tape-scan memory circuit 202 is placed in tape nonscan mode and the timer 204 is reset to inhibit the generating circuit 203 from operating. Consequently, this program searching device facilitates program search for desired pieces of music and is mounted suitable on a car.

Title: Optical beam light quantity correction of image forming device
Inventor: KANEKO MASARU
IPC: B41J2/44
Filed: 1989-02-22
Abstract: PURPOSE:To improve precision of input of an inspecting sensor by a method wherein sequence control which shifts to preparation for reading a second density from a point of time when no noise could be conformed in the case where detection moves from a first density to the second density, is performed. CONSTITUTION:A control system is composed of an image processing part A, a print sequence control part B, a laser diode unit part C, a high voltage power source supply part D, both detecting sensors 14, 15 of a photosensitive material peripheral part, etc. After end reading surface density (first density) of a photosensitive material part with an image density detecting sensor 14, the read input voltage is successively checked.

Title: Noise removing circuit for receiver
Inventor: MASUDA YUKIO
IPC: H04B1/10
Filed: 1987-02-25
Abstract: PURPOSE:To accurately remove a noise by executing the detection after being amplified with a high frequency amplifier for receiving a signal and further, detecting a noise component included in the A/D-converted signal after it is amplified by the high frequency amplifier for receiving a noise. CONSTITUTION:Since the high frequency amplifier 21 for receiving a signal and a high frequency amplifier 22 for receiving a noise are one and the same characteristic, a noise component (Vn+Vin) included in the digital output Fd1 of a first A/D-converter 26 becomes equal to the noise component (Vn+Vin) of a digital output Fd2 of a second A/D-converter 29. Consequently, when the exclusive OR of these Fd1 and Fd2 is obtained, a noise component Vn and an internal noise Vin included in an objective signal Vs are cancelled and only the signal component of Vs can be obtained at the digital output of a digital comparator 30. After a digital output Vs is converted to an analog signal by a D/A-converter 31, it is amplified by an output amplifier 32 and removed as the low frequency signal without having a noise.

IPC: F23D14/54
Filed: 1988-02-25
Abstract: PURPOSE:To prevent harmful matters from flying between a nozzle tip and torch head and to seal them safely and easily by melting a phenol resin and extending the melt into a thread and after spinning the thread into a string and immersing it into teflon solution to form a string packing and putting it into the annular housing section of a back nut and tightening the back nut. CONSTITUTION:A packing 16 in the shape of string is formed by twisting three pieces of strings which are made of a string of about 0.8mm diameter to be produced by spinning threads. Those threads are made by melting phenol formaldehyde resin and extending the molten resin into a thread. After the packing is immersed in teflon solution, it is dried. The packing string is cut in a length which is long enough to wind the thread round the stem 25 of a main body 1.4-2.5times. Then as a piece of the cut string is wound on the spiral groove on the stem 25 of the main body, the string is received in an annular housing 15 in a back nut 14. Next, the back nut 14 is rotated so as to tighten it and as the string body is crushed by the end face of a torch head 1, the back nut 14 is tightened by a torque of 100-150kg-cm to provide an airtight sealing between the stem 25 of the main body and torch head 1.

Abstract: PURPOSE:To improve the contacting of a cleaning blade with the surface of a photoreceptor and to reduce variance in press-contacting force, by holding the cleaning blade at an acute angle of press contacting at an uncleaned side and specifying the center position of rotation of the cleaning blade. CONSTITUTION:The blade 3 is supported by the 2nd holding part 6 through the 1st holding member 4 and the 2nd holding member 6 rotates around a rotating shaft 11 by a spring 9 locked to the end shaft part 7 of the 2nd holding member 6 to bring the blade edge into press contact with the photoreceptor 1. In this case, the uncleaned-side angle theta of press contacting at a press-contacting point Q is held to be acute and 1<=l2/l1, where l1 is the segment connecting a center O of rotation and a force point P, i.e. a press-contacting force impressing part and l2 is the segment connecting the center O of rotation and press-contacting point Q. Thus, the blade 3 contacts the surface of the photoreceptor 1 excellently and the variance in press-contacting force is minimized.

Title: Setting structure for power line

Abstract: PURPOSE:To reduce the overall width of a track without making any functional sacrifices, by forming a side wall, locking a setting device for a power line, into a concavity, while attaching the power line setting device to the said concavity. CONSTITUTION:A power line 2, being supported by an insulating material, is attached to a side wall 1 through setting devices 5 and 6. Likewise, a concave part 7 is installed in the side wall 1, while thickness in the side wall 1 where these setting devices are installed is substantially thinned as compared with other parts, but a drop in strength per unit area of the whole lot of the side wall gets off with a bit. At this time, they are set up so as to secure an insulating distance Z between a support device 4 and the side wall 1 and simultaneously an insulating distance Y of the power line itself is also secured in relation to other parts. With this constitution, width is reducible as much as a portion for depth measure M of the concave part 7 installed in the side wall. This measure M takes different values according to materials making up the side wall and/or its design. That is to say, since the measure required for a setting device part for the power line is extremely larger than the measure required for a general part of the line, this differential portion is absorbed by the side wall whereby a useless space is eliminated as a whole.
